IMPACT OF CLIMATE CHANGE ON GLOBAL AGRICULTURAL TRADE PATTERNS
1. CLIMATE CHANGE AND AGRICULTURE
Climate is continuously changing and this change has serious impacts on agriculture and food
production systems globally. World climate change is increasing the temperatures, frequency of
worse weather conditions and changes in precipitation that affect the production of crops and
animal products, gradually altering the structure of trade exchanges for some of the most
important agricultural products. The opportunities and risks that climate change brings to major
crop exporting areas are productivity and crop suitability, however, there are some regions,
which experience cooler climate, benefit from better conditions for the production and export of
crops. The current modeling research suggests that owing to climate change, the yields of the
major crops grown in the tropical and sub-tropical areas of the world will be reduced by the year
2050 that are mainly controlled by India, Thailand, Vietnam and Brazil. This would have an
effect of lowering the volumes of trade in international markets for staple foods such as rice,
maize, soybeans and coffee. At the same time, warming can be seen as offering potential to
widen the frontiers of the agriculture in the higher latitudes such as North America, Russia, and
Eastern Europe. For instance, research done on the-Northern Plains of the U. S., indicates that
soy or other crops- planted acreage and exports may significantly increase with the rise in
temperatures. Canada and Russia have equal crop production capacity as previously frozen areas
become more producible. To unlock this potential, there will be significant changes in both the
agriculture systems and the investments in trade infrastructure. Therefore, while climate change
could potentially reduce export capacities in some of the conventional large scale exporting
zones, it will also foster new opportunities in the form of emerging agricultural export economies
to redefine the existing global export patterns. The future transformation of human development,
P a g e | 2
learning and communication to adapt to this shift in a sustainable manner while preventing
negative or maladaptive behaviors will require active research, infrastructural development and
supportive trade and policy frameworks. Changing roles of agricultural exporter countries affect
food security, farmers, and the state of ecosystems in the connected trading nations.
1.1. Global warming trends
The global average surface temperature has increased over the past century and it has posed
worrisome trends for agricultural systems globally. Currently, there are higher levels of emission
of gases like carbon dioxide and methane in the atmosphere; hence, the average global
temperatures are rising very quickly than the rate at which ecosystems are able to cope with the
change. This leads to change in the geographical distribution of precipitation with increased
rainfall in one area, coupled with long and severe drought periods in other areas. Water scarcity
is a common issue that many agricultural lands face, and the situation is expected to deteriorate
with climate changes. At the same time these warmer and often wetter conditions allow increased
growth of crop pests and pathogens that do well in warm and moist conditions and further
contribute to crop loss that requires more chemical inputs to be countered. However, these yields
still remain a subject to decline as temperatures exceed optimal conditions for many of the basic
crops during their sensitive development periods. Heat stress reduces yields of food crops like
the wheat, rice, maize and soybean, commodities that are of significant importance in the global
market. However, as warming continues, reduced global emissions will fail to prevent up to a 30
percent or more decline in yield in many present breadbasket areas of North and South America
as well as Asia well before the middle of the current century. Such losses are not only
catastrophic for national and global food security but also have dire consequences for the local
and global communities. Of the two proposed scenarios, one pertains to the movement of
P a g e | 3
agricultural zones to higher altitudes and latitudes which while less certain than the large-scale
transition scenario cannot fully offset losses in currently productive agricultural areas. Some can
be avoided, for example, through the use of more appropriate practices in land management, by
switching to heat and drought-resistant crops or through construction of sustainable irrigation
systems. However, there remains the challenge of ensuring that the agricultural systems in the
world continue to feed the ever-increasing populations which is a challenge that economically,
logistically and socially has not been easily solved in the developed world let alone the
developing world. The global society needs to embrace ways of taking proper action on climate
and promoting climate agriculture to reduce the ramping up of warming processes while
promoting adaptation where change persists as inevitable. Giving the ‘climate beat’ a miss puts
global food security and consequently global stability under increasing risk.
1.2. Changing precipitation patterns
Climate change continues to cause changes in the distribution of rainfall and the resulting effects
on agriculture production remains a challenge in the current world. It is being predicted that,
several parts of the world may face an overall decline in the sizes of precipitation, less
predictable rainfall, and an elevated susceptibility to both floods and droughts. It affects crop
yields directly through water deficit stress and vice makes it harder to carry out irrigation when
the precipitation is declining. In actuality, even those regions which have been experiencing
enhancement in precipitation may realize that the timing of rainfall is unfavorable in relation to
the stages of key crop development. Higher variability in rainfall also leads to increased
uncertainty in production and resource allocation within agriculture, since farmers cannot predict
when moisture is appropriate for seeding or applying fertilizers and when crops will be ready for
harvesting. Flood hampers future crops operations, erasing entire crops, and drought reduces
P a g e | 4
yields, causes crop and livestock failure. Of course, shifts in rainfall may affect relationships of
trade between countries that produce food and those that consume these products as well as the
relative advantage of certain areas, for example, some areas that are currently endowed with
water-intensive resources such as rice or cotton may lose their competitive edge if water
becomes scarce. While some regions, such as breadbasket regions, could experience changes in
growing conditions and precipitation for the better in terms of cooler, temperate climates. It is
important to gain awareness of how climate change affects precipitation in various areas of the
world and how climate change may affect other aspects, such as local food production and
income in some regions. Preventive measures are required for today, right from drought and
flood resistant crop variety, better techniques of irrigation, better water storage capacity etc.
There are also various ways that can be useful in managing conditions which may be brought by
climate variability within the farm such as crop diversification, insurance and climate
forecasting. Addressing destabilized precipitation will prove critical to ensuring global food
security and maintaining agricultural lifestyles into the next few decades. It is expected that the
variations in the effects of precipitation will be highly differentiated across the regions, which
underlines the need for finding out specific policies on supporting agriculture and relevant
measures corresponding to the concrete regional climate change consequences in terms of water
availability and concentrated precipitations.
1.3. Extreme weather events
The global warming has led to the enhancement of the intensity and prevalence of severe
weather conditions such as heat, dry spell, flood, hail storms and hurricanes among others. These
extremes are already presenting real vulnerabilities to the agricultural sector in countries across
the world through direct and indirect effects on produce, animals and infrastructure. Hatch and
P a g e | 5
Handberg (1992) opined that high temperatures which may lead to heat stress for crops are
detrimental specifically during the development stages. On the other hand, warm early spring
temperatures may fasten the rate at which crops are being produced making plants succumb to
frost at this time of the year. It also affects the health and productivity of livestock for example
reduced reproduction rates, poor milk yield and death. At the same time, drought reduces water
that is necessary for most of the production in agriculture and the pastures and ranges. During
dry season, crops slow down their growth and produce less food; animals are sold off when there
is no more grass and water to feed on; diseases also increase resulting from overcrowding near
the few water sources available. On the other hand, excessive rainfall and floods are detrimental
to the growth and development of crops through encouraging crop disease infection, eroding the
soil, delaying planting due to the inability to access the planting field because of water logging,
and direct destruction of the crop by water through washing of nutrients and availability of
anaerobic conditions due to waterlogged soils. Moreover, the weather extremes cut off key
supply chain, aggravate compound feed scarcity, and knock down essential transportation
networks, silos, and other agricultural structures. Some regions will gain from the changes in
growing conditions under gradual climate change while the agriculture is exposed to acute
weather events outside the historical conditions and potentially simultaneously in major
production regions that threatens the world food security. This position underscores the
importance of adaptation measures in the management of farms, as well as in farming structures
and policies in a future characterized by frequent and serious weather shocks.
1.4. Impact on crop yields
For a long time, climate change has been an essential factor that affects crop yields all around the
world. New and excessive heat, differential rainfall, and an increase in the frequency of climatic
P a g e | 6
events are also changing the growing conditions in many agronomic zones. Heat stress interferes
negatively with the crops and results in yield reduction. Hab Anal Heat stress above the optimal
conditions for photosynthesis and pollination has already reduced yields in tropic and temperate
crops such as wheat and maize. Concerning the effect of precipitation changes on soil water
availability and plant photosynthesis, the following conclusions and recommendations can be
made. Drought stress is characterized by water scarce while flood stress on the other hand is
characterized by too much water that damages the crops. Climate risks such as heat waves,
floods, and droughts are more frequent and frequent leading to risks and low production in
farming. On the other hand, high levels of carbon dioxide enhance the plant growth and their
ability to use water to produce food in suitable temperature and humidity conditions which has a
capacity to enhance the yields of crops. However, these potentials for increased productivity can
be erased by stresses occasioned by high temperatures and changes in rainfall patterns. It is still a
difficult decision for farmers to decide on suitable crops to plant when the temperatures are
rising, precipitation rates are changing, and carbon dioxide levels are increasing, which all
combine to produce unstable growing conditions. The IPCC has projected that various regional
studies for the impacts of climate change suggest there may be a cut in global crop yields
anywhere between 5-25% by 2050. This is indicated by the large range of outcomes which are
attributed to the existing uncertainties regarding precise local climate changes and biological
crop responses. Nonetheless, the overall implication of climate change is that it carries potential
threats to agriculture, more especially to the tropical region. This could be done by observing
crop performance in different environments and making early attempts at adaptation, of course,
creates the best chance to produce good yields. Planting time management, utilization of stress
tolerant crops, better irrigation facilities and selective use of fertilizers can be some useful
P a g e | 7
strategies which may be helping the farmers to cope up with the climatic changes in the
forthcoming decades. The global effective mitigation action would decrease the long-term risks
but adaptation would still be inevitable to some extent.
1.5. Shifts in growing seasons
Currently, climate change is gradually leading to an increase in global temperatures and therefore
the seasons favorable for crop growing are progressively changing. What this means is that
critical events in the agricultural calendar such as planting, flowering and harvesting are
occurring at a higher or lower temporal frequency than formerly. One of the reasons for this shift
is climatic conditions with regards to temperature and rainfall resulting from climate change.
High temperature accelerates the process of maturity of crops through causing early flowering
and maturity for harvesting. Shifts in precipitation distribution also affect water availability in
the soil, environment for plant growth and phenophases of plant development. These changes in
growing seasons are multifaceted regarding the effects they have on agribusiness across the
world. In some of the higher-latitude areas, longer and warmer growing seasons provide farmers
with opportunities to cultivate crops that were in the past unable to be grown to maturity or
produce greater crop yields in the existing climates. However, the short growing seasons in the
lower latitude regions lead to low yields of some of the stapes foods such as rice and maize and
hence affect food security in those regions. Seasons also disrupt optimal timing between crop
development and phases of the climate that they need such as water, and pollinating insects.
Farmers must forever be alert, and may have a reduced timeline for planting or harvesting.
Another potential adverse outcome is that connected crops and supply chains across areas may
become desynchronized. Changes in the seasonal patterns in relation to climate change are a
threat to agriculture and food chains globally. The planning and formation of agricultural policies
P a g e | 8
have to take this particular impact into consideration, as the seasons, on which a significant part
of the global agricultural cycle depends, are no longer a constant. Enhancing adaptive measures
in production, distribution, and consumption will therefore be crucial when uncertainty increases
in climate change in the next few decades to guarantee food security and rural
livelihoods. Climate change models forecast increasing rates of disturbance to agriculture,
meaning continual evaluation and modification of the sector’s frameworks will be required.
2. AGRICULTURAL PRODUCTION CHANGES
Global warming puts the agriculture industry at risk of a huge disruption across many areas, they
may also be subjected to longer periods of drought, heat waves and other forms of extreme
weather patterns like floods and storms that affect crop production. Other locations may find that
longer durations for plant development and warmer climate enhance the productivity on some
crops. Global trading partners that find their comparative advantage lowered will have to adapt
to the changes and look for new partners to balance their production. For instance, increased
length and warmth of growing season may bring large benefits to grains and oilseed production
in the United States and Canada. In current analyses a very high yield by mid-2050 is revealed.
Higher levels of CO2 also promote plant growth a factor that may result into higher yields. On
the other hand, a large number of developing countries in lower latitudes have already attained
near or above the above-mentioned critical thresholds for crop productivity. More extreme heat
could significantly reduce yields in the future, which is damaging to the production process.
Movements of species occur in poleward or upward directions when the climate warms, affecting
precisely which specific crops can be cultivated. Climate variability – and changes thereto – pose
a significant risk to future food production systems upon which future food security depends.
Fluctuations in oil and grain prices may become more evident if shorter temporary supply
P a g e | 9
shortcomings stem from more frequent extreme weather occurrences. National food security
concerns can cause a call for export restraint even as the world is optimizing for more
agricultural performance. Essential LDCs with increasing food requirements are located in
tropical and subtropical areas to some extent. Farmers could experience steep yield reductions,
insufficient water, and greater hunger—which has pushed adaptation to climate and crop
development to the forefront. This is because protectionist policies towards the enhancement of
within-border food security could lead to the emergence of trade barriers. On the supply side,
food aid and key import may be limited resulting to serious malnutrition issues that will affect
many countries especially the low income and rural dwellers.
2.1. Crop migration
Since climate change and global temperatures are ever on the rise, the places that can support the
production of most of these crops is becoming limited. This crop migration has already begun to
affect food production in the traditional exporting agricultural producing countries and changing
the previously existing patterns of imports and exports of some of the most important food crops.
Rising temperatures are extending crop ranges in the polar directions and forcing farms to move
in order to where they plant crops. However, the pace of change is not consistent and the
adaptive capability of regions is also different; the ones most vulnerable are which depend highly
on Climate-sensitive agriculture. For instance, it reveals that warmer winter could lead to new
opportunities in the next few decades for soybean and corn cropping in regions that are currently
unsuitable such as Canada and Russia. As the temperatures rise and heat stresses increase in the
US corn belt, the production may either plateau or decline, and thus, the northern regions have a
higher chance of capturing a larger market share. Scientists expect that due to climate change and
the potential shift of frost-free period, an additional 26 million of acres of land in Canada could
P a g e | 10
be farmed in the future by 2040. If materialized, this would be a rise in output from other
countries, particularly non-traditional ones such as Canada and Russia who employ superior
agrotechnology, potentially reducing US exports. analyzing commodity trade outlooks indicates
that the Corn Belt states such as Iowa and Illinois may be pushed out of the corn, soy and wheat
export markets by new entrants from the north within the next two decades, thus marking the
start of shifts in both buying and selling power. At the same time, crops in regions warmer and
drier closest to the Equator confront increasing challenges. Research shows that the areas that
can grow coffee, cocoa and six key grains in Central America, Africa and southeast Asia are
projected to shrink or shift to higher altitudes by the middle of the century. The developing
countries in these regions are still unable to provide farmers with adaptive capacity and capital to
facilitate the crop transitions. This approach fails to support farmers and agricultural transitions
during climate change and might disintegrate the local farming economies of the coastal areas to
increase dependency on imported grains and commodities to feed growing populations which are
vulnerable to price volatility. Consequently, paying attention to crop migration patterns across
countries will become progressively crucial for identifying which nations and areas may gain or
lose influence in determining the balance of agricultural trade in the coming century as climate
change alters the climatic and weather conditions that can support crop production.
2.2. New agricultural zones
With climate change now trending the increase in temperature and changes in rainfall regime
around the world, new regions are now being created for agricultural production. Traditionally,
crops have been cultivated in areas that have favorable temperatures – temperatures that are high
enough to facilitate growth, yet not too high to hamper fruit formation and dryness. However,
increasing temperatures are changing these latitudinally favourable growth regions towards the
P a g e | 11
poles. For instance, regions in the extreme cold of Canada and Russia that previously lacked the
climate that would sustain crops such as corn, soy, and wheat can now enjoy relatively longer
periods of frost-free growing seasons and adequate warmth to grow crops. The trends of
identified key grain is shifting northwards at a rate of 30 to 40 kilometers per decade in areas
such as North America, Europe and Asia. This shift of the desirable cropland toward the poles
means that new large areas, many of which were before a part of forest, marginally arable, or
unused at all, become available for cultivation. Russia, Canada and Scandinavia will be the
biggest beneficiaries and will acquire the most productive agricultural soils due to increasing
temperatures in the northern latitudes. Most importantly, these higher latitude regions are gaining
more arable acres, while existing agricultural regions near the equator become detrimentally hot
and arid. Drought stress and heat waves are lowering yields in tropical crops, which were
historically characteristic of tropical regions. This may mean there is need for change in the
nature of crops that are grown in these areas. For instance, some regions in Mexico may shift
from the cultivation of corn, which is suitable in cooler climates, to crops that can be grown in
high temperatures. The increase in the arable land for agriculture in high latitude and the decline
of agricultural land productivity in the low latitude will shift the global trade patterns. Some
countries such as Canada, Russia, and the northern European countries may greatly export crops
whereas countries near the equator line may greatly import foods. Distribution patterns and
trading networks will be changed. These dynamics show that climate change puts a significant
pressure on the agricultural potential of the regions and this pressure is expressed in numerous
forms.
P a g e | 12
2.3. Water scarcity issues
Water plays an important role in agriculture, but climate change is making its availability a rarity
in many parts of the world, climate change leads to a rise in temperature that in turn increases the
rates of evaporation of surface water resources. Climate change alters the patterns of
precipitation, which affects monsoons and rains that are critical in watering crops for
farming. Long-continuation periods of dry seasons are becoming a potential danger to significant
farming zones across the globe such as the USA, Brazil, Africa, India and China,
Australia. However, it accelerates the glacial melt that leads to flooding during early stages and
which destroys crops and other infrastructure. But when the glaciers melt, areas that are under
threat such as the Indian sub-continent is left with permanently reduced volumes of water during
the dry seasons for the rivers and irrigation. Lack of water decreases everything, ranging from
crop production on the farms to farm income and global food production. Because the population
has decreased, farmers do not have enough water to grow the same amount of crops. Water is
important for growth and development at certain stages; if the crops lack water they wither away.
The lack of efficient water provisions that cannot support the required irrigation volumes means
that farmers must plant fewer acres. For instance, scarcity of water and government’s limitation
of pumping GWs has been reducing Agricultural productivity in big grain and cotton-growing
states of India such as Punjab. Current climate reveals that the Brazil soybean farmers are
constantly faced with drought related challenges. Since 2006 more than half a million acres of
cropped land has been left uncultivated in California’s Central Valley due to shortcoming of
irrigation water. Consequently, with lower yields there are higher prices for commodities and a
higher overall value of trade in agricultural products. Countries then adjust trade as a result of
more limited domestic availability and higher global food prices. Key buyers switch to other
suppliers of the sourced good from countries that offer lower costs. As drought deprives
P a g e | 13
Australia of big crop, Mideast nations that rely on import look at Black Sea wheat. Increased
food imports for China, India and Sub-Saharan Africa due to water stress leading to higher trade
deficits. The decrease in production from giants of agriculturally exporting countries such as
United States, Brazil and Australia hinders global trade volumes even more. This disrupts the
usual trading relationships between partner countries; water scarcity across the major farming
regions means that.
2.4. Pest and disease prevalence
Agricultural productivity across the globe depends on factors such as pest and disease
rates. Changes in climate mean changes in environment and consequently changes in geographic
distribution, incidence, and intensity of plant pests and diseases. Higher CO2 concentrations in
the atmosphere can also elevate the vulnerability of livestock to some diseases; high
temperatures affect livestock as well. All these impacts will demand shift in management
practices in agriculture, alteration of yields in crops and productivity of livestock, and alteration
in the trade patterns. For instance, global warming leads to a favorable environment for the
development of many insect pests, which in turn shift their range northwards. This ensures high
overwinter survival rates and production of multiple generations within a single season hence
leading to more enhanced or increased infestations. Species and areas not formerly infested with
particular pests will need fresh indexes of surveillance, management, and restrictions on
quarantine to avoid getting infected. Current integrated pest management strategies may not be
as useful as before if climate affects pest development and biology. Higher temperatures also
increase the rate of growth of pathogens such as fungi, increase weed pressure owing to rates of
growth, and enhance the transmission of viral diseases through vectors. In any crisis, the risk
increases in heat stress, vector-borne diseases and water and food contamination to the
P a g e | 14
livestock. As for the consequences of the shift in pest, disease, and weed dynamics in agricultural
systems, they are often vast. Any legally mandated actions, for example, pesticide use or tilling,
come with production costs for producers and drawbacks in terms of environmental impact.
Inability to harvest or reduced yields due to organism breakouts in farms affects the supply and
income. If importing countries decide to impose phytosanitary measures then trade is affected
particularly if the insects are quarantine pests. Agricultural importers may face pressure from
countries where their products are being imported to carry out risk assessments and pathogen
testing to confirm that their produce is not contaminated with pests. Some areas might face loss
in their market competitiveness due to increased endemic pests if climate change makes the
situation worse compared to exporter countries with less favorable conditions for pest
outbreaks. Combined, the implications of the shifts in pest and disease distributions point to the
fluidity of agricultural yield and global food security in the context of climate change.
2.5. Adaptive farming techniques
With changes in climate right across the globe, the appropriate techniques used by farmers in
different parts of the world are applied whereby croplands meet temperature and precipitation.
Farmers do not have the ability to change larger climate impacts of a system but they are able to
apply smaller scale solutions that reduce the immediate consequences of the climate on farm
land. Strategic crop selection means selected crops should fit the expected conditions some crops
can better withstand heat and aridity than others can. Changing planting periods helps to reduce
the impact of unfavorable weather conditions with certain stages of plant development. Drip
irrigation, moisture sensors, laser-leveling fields for better water usage also reduces wastage.
Incorporation of this type of agricultural practice where several crops are grown in one piece of
land minimizes the likelihood of a complete failure. The integration of trees in farming, produces
P a g e | 15
microclimates that retain moisture and protect crops from blown by winds. Shelter or windbreaks
are used to protect crops from high or low temperatures and intense wind. . Genetically modified
seeds are those that are able to thrive well in difficult conditions of stress. Deciding trait-specific
varieties targeting matching the testing environments at the site level. Indoor vertical farming
services the growth of climate control, enables permits for year-round growth, and remains
unbothered by the external climate. Swapping lands inferior in the future conditions turning
grazing pasturelands forests which are more apt to forecasted rainfall, and temperatures.
Croplands shifted polewards as climates and precipitation advanced northwards and up in
altitude. Facilities and structures that have lengthened irrigation systems and reservoirs to
provide water are required. As societies grapple with intensified pest disease resistances.
Reduced tillage, use of cover crops, crop rotation, the application of organic matter increases the
ability of the soil to resist degradation and improve its structure. Insurance financial risks provide
a safety net, protect the failed harvest. Finally, the interaction of the PPP sectors together with the
coordination of different nations necessitated the creation of frameworks for transition, the policy
uncertainty requires flexibility to create systems that allow for responses as the climate effects
come out. Where climate change undermines the ability of farmlands, farmers possess
instruments to lessen effects by strategies of adaptation maintaining production adjusting to
conditions and reorienting yields.
3. GLOBAL TRADE DYNAMICS
Climate factors such as temperature acting on commodities, rainfall, and climatic shocks and
variability that include droughts, flood, and storms have a direct impact on the production and
trade of agriculture produce in the global market. Climate change which is a continuous process
means that over time the comparative advantage shift from one region to another concerning
P a g e | 16
which crop could be grown most profitably. Due to climate change, some regions dry up, become
wetter, warmer, or cooler, and so the type of crops suitable for such climates also alters. For
instance, research done in the future climate change suggests that it will increase production of
soybeans and maize in North America over the coming decades while decreasing production in
some Latin American, African, and Asian nations. This may help the United States to improve its
export of maize while providing Brazil the opportunity to increase the export of soybeans. While
some countries will experience elevations that will make them less suitable for growing quality
Arabica beans since the plant can only withstand low temperatures, coffee producing regions in
Central America, Africa and Asia will be the most affected. Some like Vietnam may end up
benefitting from a comparative advantage in the lowland Robusta coffee type. Higher levels of
atmospheric carbon dioxide could also help some cereals grown in temperate regions such as
wheat and rice while, at the same time, harming the tropical crops. For palm oil production,
extreme heatwaves, and changing monsoon rainfalls, the rising seas could make new lands for
palm oil production in the long term only in Africa and South America. It might have a negative
impact on agricultural productivity in warmer lower latitude countries but could be conducive for
production in colder climates such as Canada and Russia. Similar changes in the climatic
conditions capable of determining the best places for growing important crops will trigger new
global trade patterns as demand is relocated. This could require, for example, that lower latitude
countries, which are net exporters of food, shift their agricultural systems and trade policies in
the face of climate change effects on domestic production potential and imports in the next few
decades. Watching how comparative advantages shift will be crucial for those in a position to
properly fund their agricultural sectors in light of climate change.
P a g e | 17
3.1. Shifting comparative advantages
When one season shifts to another, there is an alteration of the manner in which crops are grown
in different parts of the globe. Some of the regions that used to specialize in growing specific
crops are now experiencing low yields resulted from high temperatures, altered precipitation,
floods or drought. At the same time, other areas are being rendered newly arable, that is, capable
of providing a home to crops that could not before. This alters the geography of competitive
advantage which relates to the relative efficiency of nations and regions in producing particular
goods at low opportunity cost. For instance, increasing water scarcity and climate change mean
that while Argentina’s soybean production suitability is high today, it is projected to decrease by
2050, whereas African countries will see a significant increase in their soybean production
suitability. Likewise, the state of suitability for coffee and tea production is reducing in Asia,
concurrently, it is increasing in Northern Europe. Such climate effects result in the relocation of
agricultural production and trade patterns between nations and continents. In the agriculture,
these shifts in comparative advantages affect the characteristics of global trade. Exporters of such
crops must reduce the production in order to be able to supply the global market. At the same
time, the emerging producers increase production of new feasible crops The result of these forces
is that the agricultural trade is characterized pressure on importers from around the world to look
for their materials and merchandise in other countries. In aggregate, these shifts can lead to food
security threats if trade patterns are drastically altered before new sourcing locations are
configured. This also has economic effects because decreased competitiveness in some countries
may be offset by new opportunities in other countries. It is possible to ease such shifts with the
help of adaptation measures to an extent. They can change crop varieties whereby they drop a
crop that is declining in rainfall and adopt a new crop that requires a different rainfall pattern
Farmers can also practice irrigation in areas that are receiving less rain. At the same time,
P a g e | 18
policymakers adjust the bilateral and multilateral trade relations, the infrastructure and the
agricultural subsidies in order to adapt the trade flows. However, embedded constraints are
placed on how well and where such change can be achieved globally. Therefore, changes in the
nature of comparative advantages are expected to occur in the international agricultural trade
system in the future decades as climate change leads to switches in the ranges of the feasible
production specializing in new crops while de-specializing in declining crops. Mitigating such
volatile transfers will be critical for food security and stable trade relations across the world.
3.2. Emerging exporters and importers
This will cause a large-scale disruption of both the production and sales of agricultural
commodities around the world as climate change progresses. Few traditional exporters of
important raw materials may experience low yields, thus presenting entrée for new export
players. Nations located at higher latitudes, including those in Europe and Canada, will be
enveloped in warmer temperatures and longer cropping seasons and hence increase production of
grains and oilseeds, among others. Russia itself is an exporter of wheat and hence can export
much more wheat if the situation permitted. It is also possible that the recent melting of the
Arctic seas can provide a better sea connection through northern routes. Some of the key effects
of global warming could include increased yield of soybeans, corn, beef and bio fuels to southern
hemisphere exporters such as Brazil and Argentina due to increased heat and reduced rainfall in
tropical and sub-tropical zones respectively. More exports may also be observed from the Black
sea countries, Australian countries and some part of African countries. China’s role as the largest
importer of agricultural products globally is anticipated to increase as water and soil resources
affected agricultural production capacity in the country, thus increasing imports of feed grains
and soybeans for livestock feed and edible oils. Other large Asian nations that may feel
P a g e | 19
production pressures because of heat or other adverse climate conditions could also gain from
increasing agricultural imports similar to China. At the same time, the longstanding exporters in
the category, namely the United States, Canada, and Australia, may have to alter the way they
distribute the land and accommodate larger yield volatilities. A reduction in exports from areas
that are long-term prone to drought, desertification, salinization, and soil degradation can create
competition opportunities for upcoming players. Therefore, the effects of climatic change might
redefine global trade flows as new players assume various roles of exporters and importers. The
scale and rate of such changes in international relations might have significant consequences for
world food procurement and food trade regulation in the future.
3.3. Price volatility in agricultural commodities
Fluctuations in prices of these commodities have been rising of recent in the world where
imports and exports of foods and other agricultural products have been on the rise. The following
are some of the factors that have contributed to this rising volatility; there is an escalating
demand for commodities across the world whereas supplies of these commodities are relatively
limited due to climate change. Some of the countries that produce these commodities put in place
restrictions on exportation; and there is an emergence of financial players venturing into the
future commodity markets. World population and incomes are on the rise and global food and
feed consumption increases at a steady rate. But worldwide cereal stocks have gone down, there
is no commensurate increase in cereal production, and any unpredicted crop failures lead to more
fluctuations in the market. These have an effect on the production uncertainties through
increasing temperatures, altered precipitation and incidence of extreme weather events including
drought, floods and frosts as a result of climate change. This is a definite trend across the leading
exporting regions, thus distorting output volatility in producer countries. Get occasional or
P a g e | 20
unpredictable export supplies from key suppliers such as Australia, Argentina, Russia and
Ukraine further contribute to high global price increases whenever unfavourable climate
conditions prevail. Certain exporters also limit exports in a bid to curb domestic food price
inflation during seasons of low supply, but again this has adverse effects on import dependent
countries as was seen in the food price hikes of 2007/2008 and 2010/11. Global inflationary
pressures also emerging from higher crude oil prices that elevate agricultural input and transport
costs; and increasing financialization because of investors’ perception of such commodities as
safer alternatives during the current global financial turmoil have also inflated commodity price
fluctuation. These multiple demand and supply pressures, climatic change and policies, therefore
show how food trade has become risky, by linking agricultural commodity price fluctuations in
integrated global markets, with ripple effects globally.
3.4. Supply chain disruptions
The disruptions therefore present very high risks to the international trade and agricultural
markets. Climate change results into increased production of storms, floods, droughts that affect
the transport sector and other industries through destruction of their transport networks,
industries and farmlands. This physical influence disrupts current supply chain modalities at the
border, regional, and continental levels. For instance, a major storm or a flood which could be a
single occurrence can disrupt many nodes within a supply chain pathway, the pathway which
includes production, storage, transportation and distribution of goods. The flood in Thailand in
the year 2011 affected several electronics and automotive industry supply chains in Asia because
of substantial damage to the supplier industrial parks. Analyzing the impact of climate change on
agricultural commodity markets, cross-market spillovers originate from supply
shocks. Temperatures have already affected yields of the staple crops in the regions of North and
P a g e | 21
South America, Africa, and Asia, in terms of heat waves, droughts, and floods. This leads to high
global prices, inflation, economic losses and farmers and consumer demos. They then opt to
employ trade policy measures such as export restrictions in order to insulate the domestic
market. Such actions are reciprocal across borders since importing countries and exporting
countries change the terms of trade due to variation in prices and supply. Indeed, overall climate
change can be understood to impose systematic risk right along the end-to-end global value
networks. The climate uncertainty impacts globalization and businesses and policymaker face
challenges with dealing with it. The following are the strategies for supply chain resilience;
strategic duplication of the suppliers, versatility between the countries and crops, publication of
the stock piles and trade policy shifts. Global trade flows are therefore threatened by rising
prospects of climate shocks to both the agricultural production and the physical infrastructure.
Climate change resilience can only be enhanced through collaborative efforts by various
stakeholders in the public and private sectors, where information flows, choices, and climate
risks’ mitigation are introduced at various stages.
3.5. Trade agreement modifications
Trade agreements cover a vast proportion of the flow and regulation of trade between
countries. Changing these elaborate contracts is a strategic course of action that helps to address
the effects of climate change on the agricultural trade across the two regions. Climate change
effects might alter the pattern of comparative advantage in the future and such changes could
make some provisions irrelevant or require redrafting to avoid the creation of shocks or
incentives that are unwelcome. More often, amendments and reviews might be required to be
concentrated on the agricultural trade since the sector appears to be more vulnerable to climate
shocks than the other industries. For instance, transitional safeguard measures may be initiated to
P a g e | 22
lessen the impact of economic losses resulting from shifts in trading circumstances attributable to
climate occurrences. These would enable temporary limitation of the importation during periods
of import surges occasioned by production hitches due to climate in other countries. It is
imperative to update the current origin rules and the definitions of provenance because the
production areas are likely to change. Preventing exceptional restrictions of exports in
extraordinary circumstances, whereby the trigger formulas that set the export limit may be
adjusted appropriately to serve the domestic food security and international market stability goals
during climate shocks. As for services provisions, greater openness in the temporary movement
of agricultural technical personnel across borders within member countries would facilitate the
sharing of adaptation know-how to areas affected by new climates and issues encountered.
Making climate performance indices as part of the criteria for access to preferential tariffs would
encourage partners and trade counterparts to adopt sustainable and climate resilient agriculture
practices hence contribute to increased climate change mitigation and adaptation among the
trading partners. The impact assessments concerning the existing and the introduced
amendments’ compatibility with climate objectives would identify modification requirements or
reconciliation points. It would be beneficial to undertake anticipatory action toward recalibrating
aspects of trade architecture with escalating climate risks at play for economic and food security
goals. When climate changes bring new factors into play, there will be a need to ensure that
mutually beneficial trade agreements are harmonized and balanced so as not to result in
disjointed policies. It also would help monitoring systems that can indicate emerging tension
points between the climate pressures and the trade rules, which would have to be periodically
reconciled. As an influential player in the global agricultural sector, climate brings down
unforeseeable factors into this pillar of the global economy, thus making an adaptable
P a g e | 23
advancement of the frameworks of its international aspect crucial for sustaining this important
sector.
4. POLICY RESPONSES AND REGULATIONS
Climate change will inevitably bring about new patterns of agricultural trade and therefore
require specific government policies or measures in the exporting and importing countries. The
intense food exporting countries are also likely to be hit by more frequent weather calamities
such as drought, floods and heat which pose a threat to crop and livestock production. State
funding for technologies that help farmers to be more resilient amidst production risks handles
production risks. Insurance programmes paying out cash to farmers when they are affected by
weather-hammered crops protect against risk. The expansion of irrigation facilities and water
reserves helps to cope with fluctuations in precipitation. Preparation can be made in advance
through early warning systems to alert ahead of an extreme event. Exporting countries involved
in agricultural trade are exposed to potential trade bans by importing nations in areas of
production shortfalls. Trade partners and regional trade agreements also have a part to play in
avoiding swift sudden shifts in trade policies. On a strategic level, stocking up on basic
necessities particularly food items that are imported provides a safety net during shortages. The
distribution of importing partners across countries minimizes reliance and vulnerability to
climatic factors that might impact production in a certain exporting country. Import standards on
food safety and quality that are exercised by importing countries, however, may present some
access to markets for exporters experiencing climate pressures. Support for building capacity
helps to ensure compliance. International, continental and country level policies also influence
the patterns in agricultural land use and production systems and commodity supply and demand
and their interrelationships influenced by trade. Environmental labels imposed on agricultural
P a g e | 24
exports let the consumer make a choice between these products based on the level of
sustainability. Climate adaptation in food systems both at the national and global levels must be
mainstreamed both in terms of investing and rebuilding the institutional setting from early risk
assessment of climatic change impacts up to the promotion of sustainable livelihoods of farming
households that bear the brunt of climate change.
4.1. Carbon pricing in agriculture
Carbon pricing measures in the form of carbon taxes or emissions trading schemes place a price
on carbon emissions in the agricultural sector and are one policy instrument that governments
can apply to encourage reduction in greenhouse gas emissions by farmers. Since agriculture
contributes more than 10 percent of the global emissions, putting a price on agricultural carbon
would help address the climate costs that the dirty practices in livestock farming, use of synthetic
fertilizer, and land clearing entail. It has been found by various modeling studies that in order to
reduce emissions from agriculture by about one third, carbon prices between and per metric ton
of carbon dioxide equivalent would be needed while carbon prices above 0 per metric ton of
carbon dioxide equivalent could trigger more radical modification. This way the government is
able to offset carbon leakage whereby production moves to other countries with less stringent
climate change policies, while raising the prices over time enables farmers and agricultural
companies to internalize climate change mitigation costs in their production, technology and land
use decisions. Other polices such as research and development funding, investment tax credits,
and subsidies for agriculture industry can complement and extend the cost-effective measures for
emissions reduction. This approach of assigning a cost to emissions in the agricultural sector
might affect trade by region since stricter climate change measures may make certain areas less
competitive than others. A way to overcome this problem is border carbon adjustments as the
P a g e | 25
fees that apply to imports mirror the carbon pricing disparity among partners. In the context of
total pricing agricultural carbon has the potential to cut greenhouse gases significantly and at the
same time produce new revenue for government. Some worries like the effects on food prices
and farming income can be addressed through proper policy strategies as in recycling any carbon
fee to encourage farmers to embrace sustainable production systems.
4.2. Sustainable agriculture incentives
National governments are coming up with policies and subsidies to encourage the adoption of
sustainable agriculture practices due to the effects of climate change. For farmers, they involve
provision of subsidies, loans and grants to undertake practices such as conservation tillage, use of
cover crops, composting and installation of irrigation equipment that consume minimal water.
They enhance the fertility, reduce soil erosion, and increase water infiltration, water storage
capacity, flood and drought tolerance, carbon stocks, and organic nitrogen inputs and decrease on
dependence on chemical fertilizers and pesticides. Technical training, education campaigns and
procurement contracts with preferences for sustainable products also go a long way in ensuring
buy-in. Additional incentives include the ability of voluntary sustainability certification schemes
that let the producers set higher prices to do so. The following are major policy measures
include Adoption of science based emission reduction targets for the agriculture sectors,
influencing agricultural research agendas, increasing stringency of rules governing usage of
pesticide and fertilizer, paying farmers for ecosystem service such as carbon capture and storage,
and withdrawing subsidies that encourage agricultural practices that lead to Large-scale intensive
production. Addressing climate change risks as one of the vectors within the framework of
sustainable agriculture and offering suitable incentives for sustainable agriculture will be crucial
for the improvement of food security and food safety in international relations as well as for
P a g e | 26
creating more stable agricultural supply chains, which are on the way to transferring to an
effective regeneration of the environment. Focus on the global inequalities in climate change
risks and the preparedness to adapt in different regions, emphasizing the necessity for technology
exchange and global cooperation, particularly in relation to smallholders in developing
nations. Symbiotic policy systems and strong financial tools will be indispensable as key factors
for large-scale transition to diverse and environmentally friendly agricultural structures globally.
4.3. Trade barriers and protectionism
Climate change has been projected to reduce the ability of the world to feed itself and indicated
that some regions will be too dry to support crop and animal production. This will call for
changes in international relations that reflect the changes that demand puts on the various
sources. Sometimes it becomes difficult for governments to meet the national food security and
economic requirements based on an integrated market for agricultural products hence they
introduce trade measures such as prohibitions, licensing requirements, quotas, tariffs and
subsidies. For countries that suffer from drought and heat for their agricultural production
dependent countries, trade barriers help to maintain the domestic stocks and avoid overheating of
prices. Yet export controls from primary suppliers limit global accessibility and add further stress
on net importing countries. Protectionism to leverage the process of deglobalization in specific
channels of trade and shield national manufacturers from the forces of imports is done at a cost.
There are injections into the international market making the prices to be high thus straining
affordability. The opportunity to purchase greater amounts of more efficient and competitive
sources from higher yielding regions is lost. To ensure continued access to global markets for
such a vital produce as grains, policy makers that are in charge of managing agricultural decline
due to climate change should look to trade arrangements. Major exporters may respond
P a g e | 27
negatively to manage the risks on the supply-side and thus accumulate reserves or even totally
ban the exportation of the product. Instead of predicting a scarcity, which leads to hoarding,
governments can facilitate cross exchange of geo-spread stocks between countries. Export
restrictions can be avoided with contingency planning from key suppliers and consumers.
Additionally, production subsidies can retain export capacity when there are climatic changes.
Ensuring that agricultural prosperity can change its structure and focus in response to changes in
regional competitive advantage is for the collective good. Trade frameworks with certain levels
of flexibility along with stability will be crucial as governments face climate impacts and risks
on the agricultural sector and their economies and food security. Substantial cooperation and
exchanges of information between the global actors can help reduce apprehensions and
animosity towards major suppliers’ responses to increasing but still, inconsistent climate
changes.
4.4. International cooperation frameworks
Policy measures and regulations that aims at reducing the risk and effects of climate change on
agriculture normally invoke government involvement and direction. But the problem of climate
change and availability of food is universal and it is confined to different countries. Thus
cooperation is needed at the international level. Regional and global collaborations can assist in
the process of policy and commitment coordination among nations towards the construction of
resilience as well as adjusting the trade flows. For instance within North America the three
nations that signed, NAFTA have a good stand when it comes to cross boarder agriculture
business. There are international standards that offer frameworks or procedures for cooperation,
these include legal instruments like treaties, agreements, and charters such as the United Nations
Framework Convention on Climate Change which offers the policy framework of climate.
P a g e | 28
Sendai Framework for Disaster Risk Reduction is also among the recommendation-based
frameworks whose goal is to manage risks such as those associated with climate change. The
Paris Agreement was the joining of more than 190 countries whose objective is to ensure that the
global average temperature rise does not exceed 2°C. These agreements’ provisions respecting
agriculture trade recognize the necessity of collaboration regarding adaptation, imports’ best
practices, and sustainability, the agreements also contain provisions on financial resources,
capacity development and technology cooperation for the countries in need. There are also a
number of other mutually complementary regional intergovernmental cooperative organizations
in the field of agriculture that adopted climate resilience like FAO in Latin America and the
Caribbean. Global climate change impacts on production and export-import patterns of major
cereals, meats and other food products affect international trade relations and rather than
individual nations resorting to protectionist measures like export bans that worsen global food
insecurity, international relationships offer nations benchmark rules and regulations on how to
cooperate and manage the changes instead.
4.5. Food security policies
Policies to address food insecurity in an effort to provide for affordable and nutritious food for
everyone have also gained prominence with climate change effects on production and trade, it is
important to note that most countries have been putting in place policies to promote local
production, strengthen food chains, trade and risk management. The ones that may require more
immediate action are; financing research and development for climate resilient crops and
livestock offering incentive for sustainable agriculture enhancement of physical infrastructures
such as irrigation, climate smart storage and transportation increasing social protection and
insurance programs, improvement in supply production forecast and modeling, negotiation of
P a g e | 29
bilateral and regional trade agreements that guarantees stability of supply during climate shocks
and establishing strategic stocks of key commodities. That way policy responses can dampen
fluctuation enhance accessibility & affordability and smoothen expectations of producers, traders
& consumers thus minimizing shocks to domestic & global markets. The food-exporting
countries, on the other hand, require consistent import through trade relationships; the food-
importing countries have to ensure that they import foods from a variety of sources and lower
importation barriers. Export controls particularly during crises require some delicate
coordination through the multilateral system. On the international level the issues of the
enhanced information flows and transparency of the rules can reduce the risks, it is imperative to
enhance institutional capacities and mobilize financial resources for climate adaptation and for
the development of food security for the most vulnerable countries. In conclusion it is thus
necessary to call for a combination of national policies with international cooperation on
technology and funding as well as on open trade and information access to avoid letting climate
change act in reverse to the world’s success in halting hunger and improving nutrition or to
disrupt agricultural trade between continents.
5. ECONOMIC AND SOCIAL IMPLICATIONS
Rising temperatures are experienced together with alterations in the pattern of precipitation and
occurrence of extreme weather events including the cases of droughts, floods and storms. These
climate impacts affect global agricultural production though in a very complicated manner.
While some regions can enjoy more time for plant growth and increase the area of agriculture
toward the poles, other breadbasket regions will suffer from water scarcity and heat stress for
crops. The constructed system of international trade in agriculture requires constant profits from
the main countries exporting agricultural products. When the quality and quantity of rain change
P a g e | 30
for different places or the overall climate shifts, relative capabilities for food production also
shift, which means that what was once favorable trade relations and market access rights are no
longer the same. Large importers want to avoid risks that are brought about by concentrating on a
single supplier and this puts pressure on the diplomatic relations. Export economies, for instance,
experience a decline in competitiveness indirectly despite their innocence while some emergent
exporters do not have the capability to expand their businesses in the international market or
even have the capacity to meet the set regulations in the global market. Fluctuations in food
production lead to ‘food price’ volatility which affects the pocket and causes social strain. Such
conditions act to decrease productivity and make harvests unpredictable, which poses a
significant threat to the livelihoods of smallholders sustained through subsistence farming. Their
coping mechanisms transmitting worse poverty, hunger, and malnutrition in the community. A
number of climate migrants shift from rural areas to urban centers and become a burden to the
required resources and services. Some try to migrate in a legal manner or in an irregular way
which raises concerns over immigration and cultural relations in the host nation. Sovereign
struggles surface regarding changes in land, water territories’ usage rights. While Southern
Hemisphere has relatively greater agricultural capacity compared to Northern states, the power
dynamics of climate negotiations flip. Authoritative literature reveals that many developed
nations concerned that climate action jeopardizes demand for emission-intensive exports from
the developing nations. These various pressures due to climate change on agriculture are
interrelated and interact through trade relations and other channels leak through social and
political ones. In this case, structures such as the food security, trade competitiveness, migration
and conflict early warning systems, all give partial views. An assessment in terms of physical,
ecological, and humanity reveals complex interactions and interdependencies.
P a g e | 31
5.1. Rural livelihoods and migration
Globally, climate change is influencing agricultural yields on various parts and destabilizing
farming communities who rely on crop and animal health to feed their families and provide
income. Due to frequent droughts accompanied by fluctuating temperatures in the areas that used
to be arid, crop yields are declining or are nonexistent, while livestock are starving and
thirsty. The income that used to be generated through these activities has reduced and as a result,
many families in the rural areas are unable to afford basic needs such as food, health care and
education. This deepens poverty and compounding already precarious living conditions in
agricultural households and farming regions. As a result, people are shifting from these areas to
urban centers in search of a stable income as those in cities are unable to contain their costs.
However, they are forced to migrate to urban areas, especially in developing countries where
urban centers do not have proper housing and other facilities to accommodate the growing
population. Inadequate planning and implementation of development results in poor urban
planning, which in turn triggers spatial development that is characterised by inadequate provision
of sanitation and healthcare services as well as policing and other social amenities. Immigrants
have to settle for casual, precarious and low-wage employment. Women, children and other
marginalized individuals are always at risk of being exploited in labor, and physical and sexual
assault and trafficking. International trade also has its consequences where developed countries
that rely on imported agricultural products, they also bear the brunt of the climate change effects
on exporting countries. Lower yields in other countries cause a reduction in the availability of
supply while domestic consumption increases with population and quality of life. Thus, prices
increase affecting negatively food price accessibility in the country. To guarantee food supply
Chains, big importers such as China and oil-MENA countries are either purchasing or leasing
millions of agricultural hectares in foreign countries consequently eliminating the options and
P a g e | 32
opportunities of the peoples living in the rural areas of Africa, southeast Asia and South America.
As critics have noted, the concentration of large tracts of land by wealthy investors may push
subsistence farmers off their land while bringing about intensive monoculture and injurious
chemical inputs that harm soil and water resources of the recipient countries in the longer run.
Through lowering yields in domestic food production and through land grabbing for export crop
production for feed developed country supply chains, climate change also drives migration due
to lack of opportunities, which only puts more pressure on developing countries.
5.2. Food price impacts on developing nations
Global warming and climate change, which entails changes in average temperatures and weather
conditions, have negative impacts on crop production in most areas of the world, this is a blow to
world food production, particularly of prime staple crops such as wheat, rice, maize, and soy
beans. As a result, the vulnerability to fluctuations in food prices has escalated during the past
decade at the international level. Given that many of these countries have limited resources for
food production and often depend on imports to feed their populations, such price swings are of
immense economic and social significance. A lot of the LMICs do not possess enough foreign
exchange buffer stock to act as shock absorbers due to unpredictable commodity prices. Where
food import expenditures are above sustainable levels this then leads to the need to cut on other
important areas of Government expenditure which is always painful, they have led to reduced
investments in such areas as healthcare, Education and infrastructure that are crucial to the
development process. Unless people reduce their impact on global climate they will surely get
worse as more severe and recurrent meteorological anomalies occur. For the vulnerable
households in the developing nations, the high price increases of food commodities and
necessities push millions of people into the realms of poverty and food insecurity for the
P a g e | 33
societies’ half of their income is spent on food. Literature coping strategies such as portion size
and quality of meals have severe impacts on health, productivity, and human capital –
perpetuating poverty across generations. Women and children are the most affected due to the
nature of the attacks and violence perpetrated by the insurgents. This leads to hunger and
malnutrition that definitely affect immune system and hence higher morbidity and mortality are
observed. This put extra pressures on already underfunded and struggling public health sectors in
poorly developed countries bearing the brunt of high disease incidences from poor access to
clean water, sanitation, and primary healthcare. Failure to address climate change will also serve
to erode key development gains evidenced by the enhanced surge towards improving the lives of
the poor across the world. Immediate policies and measures should be developed to enhance the
vulnerability of the food systems of developing countries through the use of improved heat
resistant crop varieties; use of technology such as precision farming, post-harvest food
processing, refrigeration and transport channels. Measures that would assist reduce vulnerability
to food price shocks include financial derivatives to hedge against food price risks as these
assists minimize the effects on government’s budgets and nutritional health of households.
5.3. Agricultural technology transfer
The world climate change is expected to significantly affect the agricultural output and trade
patterns in a big way. Habitat: some of the regions are expected to experience the increase in
growing periods while the other regions will experience decreased yield and growing viability
due to opening of the new areas for cultivation. One of the decisive factors will be the regions’
capacity to implement new technologies or farming practices that are tailored to coping with the
changing climate. Ensuring easier access and transfer of such climate-resilient technologies shall
prove crucial in avoiding negative effects of climate change, for especially the developing world.
P a g e | 34
Agricultural technology consists of better seeds, watering techniques, and fertilizers, pest and
disease management techniques, and farming equipment and many others. Transfer may take
place through investment in the form of FDI, joint ventures between countries and
multinationals, education and training, licensing and imports of capital goods and
technology. More capital investment and education requirements are critical for absorption and
efficient use of new inputs. Local adaptation also optimizes gains according to the environment.
International trade acts as a channel with imports represent technologies imported from other
countries, and processed food exports contain techniques on how to meet strict quality
standards. It also enables developing countries that are affected by climate change to make use of
agricultural technology to ensure they sustain the production rates as the climate conditions
worsen, it provides strategies on how to deal with obstacles to productivity associated with rising
temperatures, water deficit, inundation, degradation of soil and shifting pest problem. Sufficient
technology transfer plays a crucial role in addressing threats to food security and relevant
population groups due to crop damage resulting from climate shocks. It also allows countries to
continue exporting when output falls and, thus prevent balance of payments issues or increase in
international prices. Moreover, the use of proficient ‘climate-smart’ technologies in the sense of
being optimized for lower GHG outcomes, increased robustness, and improved efficiency will
enable countries to advance on better development paths despite the climatic changes. To address
this social issue, the policy of providing technological support through trade, aid and foreign
investment will therefore be continued.
5.4. Changing consumer preferences
Global climate change which may be attributed to change in weather patterns and increased
climate variability is a factor that has affected agricultural productivity in many areas. Overall
P a g e | 35
production levels are decreasing on the areas that are exposed to more frequent and severe
droughts, floods and heat stress as well as diseases due to climatic changes. Likewise, certain
polar areas are facing longer and warmer periods of crop production that enable them to increase
their productivity. These climate impacts affect the global trade since reduced output in some
countries means that they acquire goods and services from other countries while countries that
have boosted productivity can also upgrade on exports. These changes in trade structure affect
the cost and market access of many agricultural products for the consumer markets around the
globe. Due to climate shifts affecting particular crop yields in some bread basket areas,
consumers look for substitute products due to the low supply in the market and high prices. For
instance, due to heat and drought stress, coffee production becomes less likely in Brazil, and
coffee becomes expensive while consumers turn towards tea. It means that the general
consumers are able to choose goods depending on its prices and available in the market. Today,
there is a growing awareness and concern with health and sustainability issues, including a
preference for vegan/vegetarian options like meat substitutes, organic vegetables and fruits,
products containing sustainably-sourced palm oil, cocoa, or coffee. Satisfying these emergent
needs in turn calls for more adjustments in the use of agricultural land and trade systems. For
farmers growing commodity crops and agricultural traders, knowledge of consumers’ needs and
how they can meet these needs through climate smart strategies such as water conservation and
use, carbon markets and agriculture, biodiversity and reducing the emissions from agriculture
and for food security in the event of climate change will enable them to remain viable.
Consumers, through their goal- related purchases including health, Triple Bottom Line
sustainability, or diet preferences, influence agricultural production and trade through market
influence. Consumers’ motivation has thus emerged as an important topic for farmers and policy
P a g e | 36
makers who desire agricultural trade, economic and social reforms that address consumers’
concerns even as climate variation shapes production possibilities.
5.5. Long-term food system resilience
The current and future impacts of climate change on food systems are important to think about in
terms of enhancing the long-term reliability of food supply chains for export-dependent
countries. Sustainable food systems are capable to perform their activities and address food
demand even in case of interruptions during some period of time. This makes it imperative to
look ahead, to organize, to commit resources, and to apply the lessons derived from practice. For
example, if a country has adopted the approach of sourcing imports from different countries, then
the risks associated with supply disruptions are spread meaning that a country relying on imports
from a certain country will not be badly affected. This is helpful in the short term when exports
drop unexpectedly as it means that there are stocks of these commodities that can be sold and
used to fund other activities. In this case, investing in local production capacity and increasing
domestic content procurement reduces the risk of relying on imports that may decrease due to
climate change. Switching from pure-bilateral trade strategies for individual commodities into
multilateral ones involving several countries allows for better realignment of supplies depending
on climate events in various regions during each season. Improving of transportation and storage
reduces losses due to factors such as storms or excessively high temperature, which may be the
case in the future. Improved global collaboration and exchange of information regarding the
crops’ production, weather condition, demand estimates, etc. enables early intervention to
mitigate shortfalls. Offering and accessing insurance helps to ensure capital buffering for
climate-related revenue swings without threatening food system actors’ incomes. Establishing the
integrated regional markets creates homogenized quality standards and regulations of the flow of
P a g e | 37
goods to counter the disparities and supply and demand between the countries experiencing
different impacts of the climate in different seasons. Promoting free trade policies helps to omit
protectionism that triggers export bans in periods of over or under supply that affects the market.
By investing in Agricultural R&D to create climate resilient varieties, it insulates the genetic
stock that forms the bedrock of food production against the adverse impacts of climate change.
These measures may require a lot of capital resources and yet they assist in averting skyrocketing
of food prices, avoiding famines thus minimizing migrations occasioned by food insecurity
which sometimes result to regional conflicts hence enhancing sustainable economic and social
development all over the world.
