ASSESSMENT OF TRENDS AND CHALLENGES IN GLOBAL WATER RESOURCE
DISTRIBUTION, UTILIZATION, AND CONSERVATION
Profound patterns and trends in availability of freshwater around the world
Water is essential for sustaining human and animal life, food production and industrial
processes as well as ecosystems but water is spatially, seasonally and temporally and extensively
distributed due natural factors and anthropogenic effects. Described by experts as anthology, just
2.5 percent of the total global water is categorized under freshwater; most of which remains
locked up. Only between a quarter and three-quarter of global freshwater is readily available, of
which a quarter is trapped in glaciers and polar ice caps and therefore unavailable for human
consumption (Gleick, 2018). This leaves groundwater which makes up 30 percent of the world’s
freshwater resources as the only available option in most areas where surface water is scarce.
However, intensive extraction practices can overwhelm the rate of replenishment and induces
problems for long-term availability as well as sore environmental impacts including land
subsidence. Fresh water in form of running water systems of River, lakes, and reservoirs only
comprises 1.2% of the global fresh water resources, although it is the most easily available water
resource which is most utilized by humans for drinking purposes, agriculture and generation of
electricity through hydro power systems (Gleick, 2018). This highly depends on the surface
water making the source highly sensitive to contamination from agricultural drainage, industrial
effluent and untreated municipal wastewater, all of which lowers the quality and quantity of
portable water. Awakening to the scarcity and irregular distribution of fresh water gives the
alarm of the necessary water management that has to embrace both the peculiarities of its
quantity and quality. Sustainable management must borrow from disciplines like hydrology, and
2
other branches of environmental sciences in order to work towards calls for ambrosial
distribution that can reduce scarcity and make clean water available in areas that demand it most
even in the future (Gleick, 2018).
Freshwater resources are unevenly scattered all the continents depending on geographic
and climate conditions over and above hydrological processes. Globally, the rainfall rich areas
especially those near the equator usually produce more fresh water than the drier areas of low or
high latitudes. For example, South America has plentiful renewable water resources; the Amazon
River provides most of the continent’s freshwater. On the other hand, areas as North Africa
together with the Middle East faces chronic scarcity of fresh water, one factor being the hot and
dry weather, low rainfall frequency and long dry seasons (World Bank, 2020). Thirdly,
mountains provide a major portion of fresh water by acting an agent for water storage where
precipitation collected from both rainfall and snowmelt supplies water-stressed downstream
areas. The Himalayas can be taken as a prime instance as glacial melt and river flows are an
important source of water that supports agriculture and domestic requirements of large
population of South Asia. Immerzeel et al. (2019) stated that water originated from this melting
glacier is important to countries such as India, Pakistan, and Nepal because millions of these
population rely on the water source for irrigation as well as drinking. Rivers and mountains as
well as climate patterns all when combined influences the distribution of fresh water resources
regionally resulting in areas of excess and deficiency all of which can only be address on case by
case basis owing to the specificity of climate and nature of the geographical feature present in
each region.
Climatic conditions and annual changes are known to affect water availability spatially
and temporally, with adverse impacts being felt where water access is already limited. A number
3
of locations have observably different monsoon rainfall regimes that give rise to cyclic variation
in water availability which influences water security and the balance of ecosystems. For
example, monsoon dependent regions in Asia receives heavy water inflows during rainy season
but faces severe water scarce at other times which impacts agriculture, water supply for drinking,
and energy generation. Likewise, relative humidity in some parts of sub Saharan Africa varies
considerably by the season, where dry seasons are characterized by a large contraction in water
availability. Climate change aggravates these seasonal variations as temperature raises, which
increases the rate of Evaporation amplifying the regular precipitation rhythms with a consequent
elevation of periods that are characterized by drought and flood (IPCC, 2021). This variability
increases the number network narratives of water stressed areas; they are more vulnerable to
climate impacts on water systems. Global warming and climatic instability in terms of rainfall
accelerate to worsen climatic conditions in areas such as the Middle East and North Africa where
water stress limits the development of social economic activities as well as exercise Sustainable
Environmental Management. The loop, according to a United Nations study, about 50 percent of
world’s population may have to face ultra-sharp water scarcity by 2050, mostly due to climate
change interventions which distort freshwater availability and amplify pre-existing geographic
disparities (UN-Water, 2021). Addressing these challenges can only entail Integrated water
management seasons and probably climate change in a strive to enhance water resilience among
different systems and people.
The significance of using the groundwater as the major source of fresh water has raised
due to recent enhancement in scarcity of the surface water resources. Since surface water is
scarce in arid and semi-arid areas or is available only fleeting, groundwater is strategically
important to provide water for various uses. This particular dependence is most conspicuous with
4
countries such as India, China and the United States, where most agricultural activities rely on
the extraction of water from the ground as well as a large populace relying on groundwater to
support their daily water supply needs. The use of this water source has been on the rise and at
un-sustainable rates, it has caused a number of environmental and socio-economic problems. In
areas that extraction is rampant, water tables have been significantly reduced, which means that
getting water from a deeper aquifer is costly in terms of energy. Also, over pumping results to
concentration and intrusion of other naturally occurring salts which makes water undesirable for
consumption and irrigation. For instance, salinization is a situation that is proving hard to
manage in some regions of India where the use of groundwater for irrigation is on the rise and
this has caused an increase in soil salinity and hence low crop yields-affecting the livelihoods of
the people as pointed out by Famiglietti, (2014). The improper use of ground water has
potentiality to affect the local ecosystems, which decreased the base flow of the river and lake
due to groundwater discharge, then it is damaging the regional water supply and biotic
community as well. The increasing use of groundwater therefore points to the need for
sustainable utilization that takes into consideration specific spatial and temporal dynamics of
freshwater availability which in this case is groundwater. Measures have to be employed in such
a way that they promote and encourage the optimum use of water, develop recharge programs
further and put restrictions on withdrawal to use groundwater in future effectively.
Population expansion as well as migration to urban areas raises demands over freshwater
supplies, which already is a limiting factor in many areas. Recent population increase especially
in urbanization especially in the middle eastern countries and some parts of the Africa competing
for water up on which there is scarcity in the cities. Population dense areas are known to draw
their water supply from sources far off, hence water use issues, especially with regard to water
5
allocations, crop up between the urban and rural populations. This can be clearly observed in
several countries across North African region whereby large urban community is favored within
water distribution frameworks. It is on this basis, that prioritization of water access can be
detrimental to the rural agricultural communities that requires water for irrigation purposes. In
such scenarios, water deficits are not only likely to undermine rain-fed agriculture and
subsequently food security and household income in rural countries. Boretti and Rosa (2019)
argue that while diverting water to urban areas in order to support the growing population, it puts
a lot of pressure on the ecosystems since these water bodies were are dried up of diverted to
support the human population. New conflict may emerge along lines of water availability, and
distribution issues because the competition intensifies social relations. Addressing this
challenges call for the development of sound water resource management policies that will be
enough to support the both the urban and the rural population. A multi-disciplinary and multi-
sectoral approach adopted during implementation of water policies, laws and strategies to ensure
that water is equitably shared, optimally used and assertive and productive both in the urban and
rural sectors is an indispensable approach towards water security. It should be the policy with
regard to the appreciation of substantial agricultural production and growth as well as the
appropriate demand for water resources with a view of enhancing the functionality of growing
urban centers (Boretti and Rosa, 2019).
Water scarcity can be threatened by drought and floods or any other extreme weather
conditions
Natural disasters including floods and drought pilfer the existing water sources and
degradation of the quality of the remaining waters pose major risks to the global and regional
water supplies and their sustainability. Floods can also over top natural and engineered water
6
systems penetrating them and bring in pollutants and pathogen into the freshwater sources hence
reducing water quality. Even when the floods impact the region, they can cause erosion of soil
and destruction of habitat, and therefore disrupt local ecosystems and opportunities to access
ecosystem services. On the other hand, drought events result into decreased water supply,
thereby straining the commands for irrigation activities and decreasing the supply of safe water
for citizens in the rural and the urban areas. Long term effects and sometimes short term effects
of drought can greatly affect crop production and lead to food and other shortages affecting the
already water scarce areas. These severe weather events also bring additional effects on
environment that are not only immediate effects but the effects of climate and water distribution
and ecosystem in duration. Subsequent precipitation and air masses circulation, land use change
and other hydrological mechanisms that might cause these unfavorable event conditions are also
important to be identified to create the suitable management strategies. Such strategies must
hinge on increasing the sector’s overall water security, improving flood-resistant infrastructure
and integrated water resources management, and land management practices. It means that there
are measures that may prevent adverse impacts of climate change and extreme weather on water
resources. Better forecasting and warning systems are the examples of such measures as well as
community programs. In addressing the described challenges, the communities will be able to
conserve water sources in order to avail clean water with the changing climate.
Floods are among the most disastrous natural disasters in which water flows through a
channel or area in excess of its normal, or comes to bear upon land that is normally not covered
by water or water comes into contact with land that is normally dry. These events have the
potential to flood river, lakes and sewage systems to their establishment causing severe flooding
in the land, homes and other major infrastructure. The result of flooding is not just scalar in its
7
physical space but in terms of its implications for public health, safety, and stability of
economies. As per the World Meteorological Organization (2021) floods impact millions of
people and economies every year and poses severe financial blows, of which the impact is very
high in the developing world. Lack of infrastructure and poor or limited disaster risk reduction
are factors that contribute to the degrees of vulnerability, in these areas flood intensification is
also blamed due to lack of infrastructure and poor or limited disaster preparedness. The other
impacts include building and infrastructure damage to buildings and transport networks include
both the direct impact of flooding, and lesser-known downstream effects into the population’s
health, and the economy, including via soil erosion, water pollution, and interruption to primary
services like healthcare and schooling. Furthermore, in the economic aspect, they caused losses
in agricultural ground, interruption in shortages, and losses in jobs which ultimately aggravate
poverty and inequality that are already there. Both social and economic effects of flood
incidences are devastating it takes many years and a lot of money for communities to rebuild
which puts pressure on the local and national treasury. It has implication on how flood can be
fought such as erecting barriers and principles for general development control for structures as
well as the provision of early warning systems. Flood prevention and control, therefore, seek to
minimize flood dangers, protect lives and property and foster sustainable development under
climate change and increasing frequency of natural disasters.
Floods are a threat to human life and infrastructure, but there are also threats to water
quality as is key to health and environmental sustainability. As floodwater can contain effects of
pathogenic agents, pollutants and a range of other solid particles, flooding intensifies the effect
of waterborne diseases and questions the quality of available drinking water sources therein. One
such case is the 2010 floods in Pakistan is the event which resulted in heavy pollution of water
8
sources with disease causing agents which when consumed by the affected resulted to cases of
cholera and other water borne illnesses among the affected and displaced population (Haq et al.,
2011). This and other similar conditions make it very paramount to focus on the disaster
response and the assessment of water quality in the event of flooding. Additionally, the flood
water is capable of widening the river flood plain and of getting contaminated with pollutants
from urban and agricultural sources and deposit them in another water body. It also worsens
water quality and destabilizes aquatic environments, as the nutrients and chemicals which
includes phosphates that result from human activity, can cause processes such as the algal bloom,
which kills water organisms due to oxygen depletion. The effects which might continue in the
years may embrace reduction in biodiversity and degrading effects on the habitat of fish and the
other life forms which are crucial for the existence of those systems. Solving these problems
calls for a complex of measures aimed at modifying and preventing negative influences of water
runoff, inadequate flood regulation and preservation of hazardous water quality by applying the
applicable land use control methods, the upgraded facilities in the field of flood control, and the
improved water treatment infrastructure for threatened water areas. These are important not only
from the point of view of human medicine but also concerning the future of water in the
freshwater biotopes and the increase in the number and severity of floods.
As periods that encompass below-average rainfall, droughts bring critical water
emergencies that have impact on humanity and ecosystem. Global warming is making the dry
seasons longer and more intense; it is aggravating other already-existing risks. NOAA has
reported that the drought season and its severity have raised in the United States over the last few
decades that have affected water supplies and crop output in the country (NOAA, 2020). Such
long periods of drought result in huge depletion of water stored in the surface water reservoirs
9
and influence the communities and the farming fraternity to go for more groundwater water in
their source of water supply. Not surprisingly, this latter reliance magnifies problems of
overdraft and inferior quality and thereby perpetuates the cycle of resource stress. For example,
recurrent droughts in California have led to massive drawdown of freshwater aquifers, which has
led to land subsidence and emerging pollution issues such as saline water intrusion and pollution
from adjacent land uses (Bork et al., 2021). Besides, drought conditions can contribute to the
enhancement of competition for water resources hence conflicts may be expected between
agricultural producers, industries, and municipal water suppliers. Disputes over water can
therefore be regarded as having implications on the welfare of a society and call for
reconsideration of meanings of the principles of water sharing. This required both, sound water
supply and demand management for delivering improved water supply options and structures
and, sound use of water practices that address challenges of drought for instance investment in
water or water conservation, efficient irrigation and other policies that support increase in ground
water. Measures such as those mentioned above assist the communities for instance reduce the
impacts of drought on water supply and the environment in general way.
The other extreme and harsh weather conditions like heat and hurricanes are more
destructive to the water sources, and all the other impacts due to climate change variation
contribute additional to disasters. By lengthening both the warm seasons and increasing the
evaporation rates from water bodies and heat waves from the soils extend water shortage periods.
For example, heat wave which was found in Europe in summer of 2003, resulted in an increase
in water temperatures in the lakes and rivers which consequently had negativities effects on
change in the aquatic ecosystems, habitat and low Oxygen on fish and other water creatures
(Schwarz et al., 2016). Such realized relationship between temperature high and low and water
10
quality imply that climatic changes need managerial responses. Hurricane and tropical storms
have high water resource through flooding, and affect water infrastructure hurting hurricane
quality. Another example of this affect came with Hurricane Katrina in 2005; storm surges
overtopped the levee, flooding most of New Orleans with water contaminated by pollutants,
debris, and nasty bugs that polluted the city’s water system. Some of these catastrophes impact
the environment leading to detriment that takes relatively long to rectify, for example, Water
sources may take long to be safe for use by the community in the wake of disaster (Graham et
al., 2011). To overcome these challenges a number of factors in which intervention is complex;
associated with specific infrastructure design details for storms, enhanced capabilities in the
prediction and warning of storms, and good practical responses and plans in the event of storms.
This is to mean that, many such measures can be pursued, raising community resilience and
preparing water supplies against extreme weather occurrences which are hazardous to the health
of community and ecosystems.
In the event that the availability and usage of water in extreme weather events, it is
therefore imperative to devise plans which enhance the capability and strength of the water
sources. Sustainable use of water therefore requires a practice of IWRM because it considers the
connection between land use, available water and the health of environment. Integrated decision
making best meets the objectives of utilization of water resources and is efficient in water
conservation and management as well as reflecting developmental needs of the community. The
developing climate-proof structures, including improved drainage, and incorporating the best
flood mitigation measures seem to reduce both flood and drought impacts. It is stated that
besides serving as a shield to the communities against threats that are central to the existence, the
insights also promote sustainable development that is in harmony with water esteem.
11
Accordingly, the knowledge creation can be also a well-understood requisite as the fundamental
requisite which is inevitable for strengthening community readiness for managing effects of
severe weather conditions. When this social focus is set, then the communities build enhanced
capacity in the direction of understanding the repercussions of the variability in climate other
than accurate measurement. Further there is need to promote the use of better and humane tiny
agriculture practices such as crop rotation and zero tillage in order to promote on the efficient use
of water in cases of dry spells when producing crops. In this perspective, improvements of the
climate change resilience in the physical properties of the soil and preserving sustainable crop
production and water storage are actionable strategies for sustainable food production today and
the future (Howell et al., 2021). Combined, such measures can contribute towards the
development of a more effective water management system that will be better placed to deal with
combined impacts of some of the severe climate conditions as both systems are safeguarded.
How does agricultural water use relate to others industries?
The supplies of water are also limited and can be applied in various disciplines inclusive
of agriculture, industries as well as domestic use. Out of these, agriculture segment more utilize
freshwater than the other segment contributing to almost 70% of the global consumption of
freshwater (FAO, 2021). It also means that a share this large also brings out the importance of
agriculture as a user of water and its use as a resource in the United States. The greatest
utilization of water is in the agricultural sector which is hiked by irrigation aims at crop farming
and animal rearing particularly in the areas receiving low rainfall. Nevertheless, the use of fresh
water in such process is worrisome due to its availability especially in water scarce regions.
Specifically, Industrial water use is only about 20% of the total water withdrawal mainly for
manufacturing, energy production and cooling purposes, while domestic use including drinking
12
water, sanitation and household uses is only 10% of freshwater (FAO, 2021). However, their
smaller amounts should not be neglected because industries and domestic use are also parts of
the total water consumption volume. Intensification of competition for available freshwater calls
for formulating alternate resource management strategies for agricultural, industrial and domestic
usage. This is because in order to achieve water conservation in agriculture, measures like
efficient water use in the form of drip irrigation, rain-water harvesting, should be embraced in
order to conserve water for future use. The efforts to optimize water use for industrial purposes,
as well as public campaigns for sound water-use practices within households constitute steps
towards reducing the stress exerted on fresh water resources. It is crucial to comprehend the
comparison of agricultural water consumption with other sectors in order to design prostrate
integrated water resources management strategy with a sustainable outlook for water resources
management.
As irrigation is still required in order to enhance crop production and thus minimize
hunger issues, it plays a role in all types of agriculture. For many developing countries, effective
irrigation has always been a need for the cultivation of staple crops, food security and better
vulnerability to climatic variability. While rainfall in the Indian subcontinent and Egypt is
known to be inadequate to support the increasing irrigation requirements for crops, intricate
canal networks that are in existence and support the farming industry (Gleick, 2018). Though it
is evident that agriculture utilizes a huge amount of water making its sustainability a big
question. Agriculture using irrigated water is generally less productive than the other sectors,
where a lot of water is wasted by evaporation, seepage and runoff. In this regard, it is noted that
the turbulence of irrigation practices differs significantly; conventional practices of cultural
irrigation often have lower efficiency coefficients than highly effective methods comparable to
13
the use of irrigation systems of the drip or sprinkler type. Using worldwide research and
information, it has been determined that, while the classical system of flood irrigation uses the
water in 40-60% efficient rates, the water supplied with the help of drip irrigation systems can be
used in more than 90% (World Bank, 2020). Due to increasing water scarcity in the world the
aspects of irrigation efficiency and similar usage of this resource are important in order to reduce
water stress in the agricultural sector. This is a state that could be augmented by the use of the
like of precision agriculture-which has been proven to increase water use efficiency and
utilization of crop rotations, management of soil moisture and the like. In this manner, achieving
the sustainable approaches mentioned, agricultural systems will provide food security with equal
consideration of fresh water foods and maintaining conservation and preserving of the remaining
freshwater for future agriculture that faces the multitude of current threats.
Agriculture is the most substantial water user, but the industrial sector’s consumption of
fresh water is also relevant. Water is consumed in several production processes such as,
production processes, heat exchange and washing. The food and Agriculture Organization
estimate that the proportion of water withdrawal in industrial use is about 20% (FAO 2021)
Some industries including the energy sector, textiles industries and food and beverages industries
use large volumes of water and may require elaborate measures to ensure that their water use
does not affect the environment in a negative way. Although industrial water usage is lower per
unit than that of agriculture, issues for irrigation involve large amounts of water taken out of the
system at one time as part of a process. In a notable way various industries have incorporated the
technologies for reusing the water and hence have lowered the total utilization of water from
freshwater sources. For example, the circulation of water in semiconductor production is only
used once, and then it is treated before being recycled back into another use reducing the usage
14
of additional water (United Nations, 2021). It means that industries also cause pollution of water
sources and affect quality of water for other uses by industries. Industrial wastes that accompany
production processes can inject impurities in water bodies causing more hurdles to water supply.
Drinking, cooking, cleaning, and irrigation water demand within homes constitutes about
10% of the global extracted water supply (UNESCO, 2021). The share of using water in
households is less significant if compared to agricultural and industrial demands, water provides
significant impact on people’s health and living standards. Water and sanitation resources are
said and should be treated as basic human rights, which if not equally provided will cause serious
health and social issues one to the other. It is evidenced that domestic water consumption is
increasing in many cities because of factors like population increase and growth of urban centers.
This growing demand of water in cities put additional pressure on existing water infrastructures
and leads to over exploitation of local freshwater resources and undue dependency on water from
provinces. Such conditions are felt most in fast growing large cities where the competition for
water between households, industries and agriculture leads to water conflicts and unsustainable
water management practices. For instance, in South African city of Cape Town and Mexico’s
federal capital, the demand has grown to alarming levels forcing the authorities to consider other
sources such as seawater desalination and wastewater reclamation. With such solutions comes
other stringencies that include costly solutions and effects on the environment. Proper water
management measures are needs since the domestic water demand is increasing and all the
residents should have to be provided with water resources. These measures may include acts as
putting in place measures that will make water scarce, encouraging users to use water wisely,
and perhaps developing poly water structures. The public prevention on sustainable practices in
15
domestic water consumption can make cities more resistant to water scarcity, protective of public
health, and a champion on sustainability of water resources.
According to the comparative analysis of the water consumption and ration on the shown
sectors, it is possible to conclude that integrated water resources Management approaches are
needed, focusing on links and interactions between agricultural, industrial, and domestic sectors.
Since agriculture is, and will continue to be the major user of freshwater, the efficient and
sustainable irrigation techniques and farming practices are the only ways through which water
stress and increased food production can be achieved. The change of this trend might require
adoption of innovative practices like precision irrigation that uses water sensors to measure the
moisture of the soil as well as the moisture-requirement level of crops (Grafton et al., 2018).
While at the industrial level, the promotion of new technologies that minimize the rationed water
use and persuasion of industries to change their ways to increase water efficiency are some of the
ways to minimize the water footprint. If the governments carry out continuous future research on
the regulation of sustainable water usage and bear attractive incentives they will reduce the
bearing impact of industrial water usage on the environment, by improving the re-use and
recycle processes of water. Hence in the domestic sector general infrastructure upgrade of the
water sector and promotion of water rationing measures become proactive measures of ensuring
adequate water supply. Such power is best complimented with awareness and education
programs with the purpose of raising public concern over water savings measures which the
public is willing to embrace. The more successful application of these strategies with all the
sectors implies that Integrated water resources management can more effectively meet the water
requirement of agriculture, industry and domestic demand at the same time as it supports the
enhancements of existing water infrastructure. An approach like this also ensure conservation of
16
freshwater and also increases the possibilities in meeting the climate and population upsurge
challenges. The approaches mentioned above therefore in their integration are core to realization
of sustainable management of the water resource, improvement of water quality, and improved
quality of lives of all people in this world.
Identifying water scarcity and water stressed regions, with particular reference to Arizona
and examples from Asia
Lack of water locally or globally is a serious threat to ecological balance, poverty
eradication, as well as disease control. There is the need for determining where water is scarce or
can be scarce so that appropriate management measures can be put in place. Arizona in the
western part of United States serves as a classic example of a region faced with acute water
shortage problem arising from a number of region specific physical and human factors. This
means that the state depends on Colorado River for water and this source of water supports crop
farming and towns. Nevertheless, the problem in the availability of this resource has emerged
from challenging times due to long dry seasons and escalated consumption as a result of the
growing human populace. In recent past, the availability of fresh water sources has reduced by
over 20 % due to climate change and persistent drought especially with regard to the Colorado
River by Arizona Department of Water Resources (ADWR, 2020). The problem is worsened by
increasing urbanization in Arizona’s cities like Phoenix and Tucson; the increasing competition
for the scarce water resources. Due to this, a lot of reliance has been placed on groundwater as a
way of combating surface water deficit, in the process causing so much draw down in the
available aquifers especially in some areas, the results are relatively astonishingly low.
Therefore, the state of Arizona has the twofold problem of meeting the current water
consumption while trying to forecast the future water usage in the context of climate variability.
17
There is high water stress in Asian regions due to; population increment, and economic
growth and climate change. For example, the Indian country faces severe water scarcity
problems in the areas of Punjab as well as Rajasthan. Some of the negative implications of rapid
agricultural development that has been enhanced by programs; Green Revolution are simply as
follows; Research shows that currently, the rates of extraction of groundwater in Punjab have
remained beyond the rates at which it can be replenished, therefore water tables are declining as
well as the quality of the water (Shah, 2017). This situation can be extrapolated to other parts
such as Arizona where similar requirements for agriculture have resulted in massive withdrawal
of groundwater. In addition, pollution and extraction of water from rivers in India aggravate
water problems, thus making it challenging to deliver clean water for drinking and fairly support
crop production. Some of the correlations that may be deduced from this paper include; First,
there is a relationship between the agricultural practices being employed and the depletion of the
ground water table as well as water quality matters hence; Second, the foregoing practices call
for overall techniques in the usage of water. The solutions to these challenges therefore involve
discourses on efficiency of irrigation water, water use and extending those discourses to include
pollution control. It is also advisable to enhance people’s recognition of the respective problem
of using sustainable water and implementing new technologies into the sphere of water supply in
order to address the demands which climate change and growing population put to the
comprehension. Through such actions, vulnerable regions experiencing high water stress can
strive for exploring sustainable water supplies for their freshwater resources, entail food security
and public health for the continually evolving global environment and progress towards
sustainable development goals.
18
The other important area for such a phenomenon is the desert areas Asia mainly china,
inner Mongolian and Xining. These areas stare development at acute water deficits as a result of
dry climate compounded by increased industrialization which further aggravates water demand
triggers. Yellow River’s incredible water extraction has significant impact on downstream
ecology and agriculture, and consequent emergent concern on sustainable water utilization in the
region (Gao et al., 2021). Drawal of water from sources is known to lead to biophysical
degradation which include reduction in on agricultural productivity, which worsens food
security. Given these challenges the Chinese government has put different policies to try and
solve issues of water deficiency. Among these are the South-to-North Water Diversion Project, a
mega project that seeks to transport water from water surplus producing regions in the south to
water-deficit regions in the north. As with such endeavors, their intended purpose is to solve the
lack of water in the short term but their sustainability and ecological effects are debated
intensely. Issues raised are the impact on ecosystems of moving water from one region to
another, effects on the ecosystem in the recipient region, and possible social and economic
impacts on communities’ dependent on the diverted water sources. As China struggles to meet
these goals and objectives its will be crucial to share water equitably between the agriculture,
industry and domestic sectors as well as water will have to be allocated in a way that sustains
ecological systems. The successful water management policies must therefore focus on the
principles of water sustainability, which address coupling of water demands with considerations
to human welfare as well as water scarcity challenges.
Comparing water deficit in arid Arizona, with the pre-sent situations in various regions of
Asia, it can be pointed out that the world problem needs local approaches. In both discourses,
physical features of landscape are portrayed not as natural phenomena, but as constructs
19
bestowed upon them by agents alone, water does not exist just anywhere, it emerges where
people choose to act including farm, develop cities, establish industries. Still, links and
coordination between measures for water resources management are less known, and since they
have to be dynamic given the reality of constant fluctuations in the supply and demand, the
existing knowledge remains insufficient to formulate a clear vision of their integrated
application. These may include acquiring modern cost effective water saving technologies,
expanding the irrigation structures as well as increasing farmers’ awareness of the optimum
water saving practices in their regions. Sensitization and sensitization become policy concerns in
observing water shortage. Because water is relatively scarce in Arizona, there is, to a certain
extent, reason to call for campaign on Arizona’s inhabitants to use limited water resources
sustainably. Programs being such can assist in raising awareness to people and societies make
responsible and smart use of water. Similar to the situation in India where experimenting has
been made in water harvesting and watershed promotion has certain effectiveness in enhancing
the water supply at the local levels and enhancing the resistance in drought occurrences. These
types of localized strategies provide examples of roles of communities and engagement system
in fostering better water regime. Nations can find effective approaches on how to operate water
scarcity within region methodologies of integrated water management strategies outcomes
cooperation of stakeholders with local government authorities in national and local levels and
industry members. Managing the scarce water, therefore, requires a combination of technology,
people’s participation, and policies in Arizona as well as most Asia’s part to support improved
water supply.
Water scarcity and the issue of water quality cannot be separated in India, which suffers
from one of the most severe water shortages and water pollution. This has led to increased water
20
pollution across many areas owing to high pressure caused by rapid industrialization,
urbanization and expansion of agricultural activities. The problem is compounded by the fact that
water consumption is on the rise and meeting the demand for safe, clean water is hard. Domestic
and industrial discharges are another source polluting urban water sources often releasing raw
sewage or industrial waste directly into rivulets and water courses while agricultural impacts
pollutants such as pesticides and fertilizers into fresh water sources. This pollution not only
decreased the quality and quantity of the products which are available for drink and other use but
also it affects the heinous result of health of these residents who directly drink these unpolluted
water. Examples of these issues are the Ganges River which has been impacted both by industrial
waste discharge and religious rites making the river system both biophysical and social
contaminated putting at risk the lives and economic welfare of individuals depending on the
river. Likewise, the Yamuna River suffers the same fate as the Ganga, and millions of people in
the National Capital Region are later affected by water pollution. Also, in regions like Punjab,
the usage of groundwater is also recorded as both over pumped and contaminated from the
irrigation sector, which results in deteriorating quality of water. It means that addressing these
related challenges require elaborate strategies with emphasis on better water management,
pollution control and congregation of people. The universalist assumption that has dominated the
water sector for several years can be replaced by a superior approach that browse both quantity
and quality concerns with an eye toward the future in India, capable of offering all citizens safe
freshwater in adequate amounts.
Comparison of Water Quantity Vs. Quality and Including Case Scenarios from India
Issues associated with availability and quality of water form some of the most pressing
difficulties in the Indian context, a country characterized by high levels of both water stress and
21
contamination. The ownership issues are another factor involving water resources; industrial
growth, urbanization and agricultural activities subsequent water deterioration in many places.
There is also an ever increasing population and therefore the need for water also rises, making it
hard to get safe, clean water. In large cities, industrial drainage and untreated sewage pollute
water sources when water treatment is inadequate; farming and irrigation release dangerous
pesticides and fertilizers into rivers and lakes. Besides reducing the available quantities of
relatively fresh water, such pollution exposes consumers of these resources as communities and
nations to numerous health risks. These challenges are well illustrated by the case of the Ganges
River, where pollution, industrial effluents, and religious activities infringe act upon the river’s
ecosystem and endangers source of living of the people depending on the resource. Like this, the
Yamuna River is severely contaminated so that millions of people living in the National Capital
Region are affected. Also, water table in areas such as Punjab, the major source of water is
groundwater, which is experiencing decline both in quality and quantity due to over exploitation
and contamination from activities such as agriculture. Solving all these problem demands multi-
faceted approaches in charge of water use, water pollution and most importantly; people
involvement. Hence, India should take a broader approach in a quantitative and qualitative
context that seeks to strengthen its water supply to everyone in a safe and sufficient manner in
order to develop a safer and fairer water future.
Ground water forms an essential element of sources of drinking water supply in India
especially in the rural areas where other surface water supply may not be easily available. One is
the growth of the population that will lead to increased consumption of this product, and the
other one is increased agricultural needs. Nonetheless, probably due to high levels of extraction,
water tables have reduced, which has greatly reduced availability for both domestic and
22
agricultural uses. At the same time, pollution of water sources is a dangerous threat to human
health; industrial emissions, and agricultural wastewater are significant factors in this issue.
Nitrate concentration and heavy metals have been reported to be higher in the groundwater of
areas like Punjab and Uttar Pradesh where large scale agriculture and Industries is in vogue.
Presence of these nasty pollutants influence the population health in a such a way that realizing
adverse health impacts of consuming polluted water becomes more than just a mere reality. This
has made diarrheal diseases, cholera and other water related diseases to become more frequent
making it more important to implement solutions that deal with both amount and quality of
water. Some fine emerging evidence that low access to safe water is associated with high
morbidity, more so among children and the elderly. The great efforts are needed in improving the
state of groundwater, integration of sustainable pumping mechanisms and optimum control and
supervision of water quality. Sensitizing societies on importance concerning water management
and anti-pollution has a positive impact within society to enhance the right protection of water
resources. The solution of these problems continues to be important for constructing now and in
advance wholesome environments for rising Indian population.
Yamuna river that is one of major rivers in India represents the problem of water quality
management under the conditions of growing demand. Because of sustained pollution of urban
wastewater discharge and industrial effluence, some sections of the river are highly polluted with
water estimated to be consumed by millions for domestic and agricultural purposes. The
management of this case shows that decreased availability of water resources is one of the
consequences of pollution with different types of water including water scarcity (CSE, 2021).
Pollution abatement measures and consideration of stakeholders involved in restoration of the
Yamuna have illustrated that the interrelated themes are not easy to address (NMCG, 2022).
23
Besides surface water supply problem, increased demand for, and pollution of water from,
groundwater sources is another case in point of the problem affecting all. Most rural households
use hand pumps and bore wells, while a poor water quality at these resources due to agricultural
pollution and inadequate sanitation is threatening the health (Shah and Van Aelst, 2019). The
existence of poor sanitation facilities and water quality is seen especially when the sewage water
flows into the public water supply bodies due to increased public health problems.
Sustainable water management for both the quality as well as the quantity can only be
achieved if the government approaches the existing problem by implementing sustainable
measures. Adopting and incorporating a high-tech water treatment system and operation of
competent irrigation that was developed can have numerous impacts on water quality and the use
of available fresh water (Kumar and Vashisht, 2020). Moreover, it is imperative that, in parallel
with increasing public awareness about need to preserve water quality, that governmental policy
and legislation are also enforced to curb the pollution practices threatening future generations of
Indian water resources. Moreover, understanding the complicated interaction between the
amount of water and water quality, they can realize necessary measures for the provision of
people with water, which will be access to sufficient and safe water for everyone.
Specific examples include Oceanic water and world water pollution.
Exactly, practice of water pollution throughout the world has real potential to jeopardize
the future state of health of both freshwater and marine ecosystems. Discharges in the form of
agricultural, industrial and urban wastes are still adding value to the quality of water in the fresh
water and marine water. Individuals are forced to endure consequences of water pollution is not
only harms environment and water resources but also harms the health, economy and life of
people and other inhabitants. Of all factors through which water pollution results, the use of
24
irrigation water and fertilizers is one that contributes to the introduction of fertilizers, pesticides,
as well as herbicides into water bodies. These chemicals cause eutrophication, which results to
waters getting overgrown with algae and plant like substance, which is robbing the waters of
oxygen. They result in hypoxic conditions hence are detrimental to fish stocks and in overall, mi
water ecosystems. For example, in the localized area of the Mississippi River and US agricultural
runoff pollutes water, and creates a dead zone because the water is unable to support the required
oxygen level to support aquatic life (Goolsby and Battaglin, 2001). Various habitats for these
species and other villager-important species remain under threat of degradation, and this prospect
is symbolized as a future threat to fishing and food consumption in the coastal region. The
measures that should be taking to control agricultural pollution include; Action towards
sustainable farming. Precision agriculture for example reduces the amount of put to use, while
organic farming reduces the readily available synthetic inputs. It again emphasizes on decreasing
chemical use and sustainability of agribusiness and water systems for the health of continued
production. The impacts of pollution affecting agriculture hence solutions to the problem of
pollution indicated that sustainable policy within the sector shall be implemented to protect the
water resources.
Many industrial processes are major sources of water pollution due to the release of
untreated or only partially treated wastes. Pollutants, such as, heavy metals, chemicals and toxins
emitted through industries pollute water bodies around them with serious health consequences to
man and other living things. The Yamuna River in India for instance has been compiled of high
level industrial pollution that has negative effects to human being concerning provision of water
for drinking and irrigation (CSE, 2021). High concentration of pollutants causes human life
adverse health effects such as gastrointestinal diseases, neurological disorders and long-term
25
effects. Furthermore, water borne diseases and catastrophes pollute water sources hence the
many losses of the aquatic life hence reducing the many species in the world. These effects are
not only physical, but due to pollution are particularly destructive to the environment, food
supply, and economy of those relying on those sources of water. The regulatory measures require
to raise the severity of requirements regarding wastewater treatment within the scope of the
industry in order to minimize such threats. It is good to note that this comprises the adoption of
cleaner production industries and technologies of production that minimize wastage and enhance
usage of water. Effectiveness in the sustainable management of water resources would therefore
be enhanced by increased public appreciation of the need to combat industrial pollution and
ensuring that the organizations responsible for polluting industries pay the price. It is as a result
of these challenges that if the government agencies, industries and communal groups join force
then different approaches can be adopted in dealing with water pollution hence improving on the
health of the public and the environment.
Plastics are one of the most acute problems of the sea which influence the sea
environment and people’s health on the international level. Annually tens of millions of tons of
waste is thrown into the sea and greatly contributes to the degradation of seas and distinct species
inhabiting the seas. Sea animals such as the sea turtles, sea birds, and fish feed and encounter
plastics and get affected in some way, even death. For instance, there is well-known issue of the
Great Pacific Garbage Patch, or an issue of plastic occupying a great portion of the Pacific Ocean
area. It is not only the fauna who is confused; micro plastic has been identified in the seafood
that the human population consumes, which gives reasons to doubt the advisability of consuming
food seemingly drowning in plastic. Preventing pollution of the seas therefore requires
international cooperation and these policies which work to help reduce wastes in the sea,
26
enhance means of disposal of wastes and provide citizens with useful information. The above
steps like prohibition on the use of the plastic bag, promotion and support of bio-degradable
items and general enhancement of the waste management system. Also applicable is the intended
cultural effect concerning awareness creation of the Population on sustainable practices, and a
overall reduction in the general use of plastics. These activities should be employed by societies
in the future so that communities can address the protection of marine environments and the
health of sea assets in societies. For this to happen, the participant is the government, industries,
non-government organizations, and communities across the world to sit together and deliberate
on the best solution on how to address those negative impacts of ocean pollution on the
wellbeing of the ocean.
The trends on natural capture fisheries and aquaculture production around the world
The fishing industry in the recent decades under goes certain transformational changes
primarily due to the new trends identified in consumer market, new technologies available and
new concerns regarding the conservation of marine species. This source of seafood supply was
formerly based on natural harvest from the global stock of fishery resources but has over time
migrated to cultivated seafood or aquaculture supply due to improved demand for seafood and
reduced wild fish stock. Aquaculture, a relatively new form of production activity in relation to
global food production, has delivered on the promise of a dependable source of fish supply, a
major contentious matter of over exploitation of wild fish supply. This transition places a
considerable degree of dynamism to fishing resources as it foregrounds basic questions on the
future of fish farming practices, their impact on the bio-system and on the overarching food
security paradigm. It is known that aquaculture has possible ways of solving such problems as
overfishing and the strengthening of local economies, at the same time there are disadvantages
27
including the destruction of habitats, pollution by fish wastes or food for fish, and possibilities of
transforming illnesses to wild fish population. However, in the case of aquaculture feeds that
utilize fishmeal and fish oil, the need for wild-caught fish is experienced. Achieving this
mandates yielding equal considerations to what aquaculture yields and what impacts on the globe
so as to protect the environment. So, future development of the fishing industry will inextricably
depend on succeeding in the solution of these challenges as well as making the further
production of seafood both safe and positively influencing the growth of world food security and
healthy state of aquatic organisms.
Wild fisheries face numerous issues, where fully, overexploitation, deterioration in the
fish habitat, and climate change lower the fish stock and the marine life. The Food and
Agriculture Organization (FAO) maintains that 34% of the world’s fish stocks are ‘over
exploited’ while a further 60% are ‘fully exploited’ (FAO 2020). This is an emerging problem
that depicts a rising degree of urgency in the practice of sound conservation and management of
global fisheries for sustainability of food security. Poverty, built due to overfishing and excessive
demand for fishes due to inadequate management increases significant concern on fish stock and
which greatly interfere with food chain and Fisher folk business. Debris in the form of pollution,
sea coasting expansion, and wrongful fishing methodologies are also argued to major causes of
habitat degradation, which worsens the situation of marine species. To overcome these problems
measures like catch of effective limits, area closure or setting of marine protected areas,
ecosystem approach to management and other necessary measures are imperative. Through catch
utilizations, numbers of fish that are caught are controlled to allow populations of fish to grow so
that there will be fish in future for future generations. Marine protected areas protect the seas or
ocean’s important habitats hence the endangered species have perfect habitats and Biodiversity.
28
Marine life is considered a complex structure of interaction with all the seafaring creatures
relying on the communities to restore the area, protect it and to bring necessary changes using
the adaptive capacity concept. They can also help to restock fish and help the seas which is the
basis of a wild fishery that plays an important role in people’s diets and the balance of bio
chains.
However, information on collective farming or aquaculture has been on the rise following
increase in demand for sea foods globally and contributes to fifty percent of the total fish supply.
This change to aquaculture is pressingly important to help to lessen the stress that wild fish
stocks have been receiving while responding to the burgeoning food demands of a global
population. New practices in fish farming practices have evolved over the years depending on
the new found technology and advancements in fish breeding and management of effects of
fishes on the aquatic ecosystem. The recirculating aquaculture systems (RAS) and integrated
multi trophic aquaculture (IMTA) are recognized innovative technologies that can improve the
sustainability of the aquaculture industry. However, essential questions concerning efficient
production completion of aquaculture services persist in relation to issues such as feed
availability for fish farming, water use, and pollution issues at fish farming facilities. Worm
derived from wild-caught fish as an ingredient for fish feed which poses challenge to fish marine
resource procurement in case of improper management, again feed management may lead to
nutrient leaching and destruction of fish natural habitats. It is important therefore that continued
development of the industry should promote safe aquatic farming in order to protect the
environment and the aquatic ecosystem in particular. Reducing the negative impact of farming
includes; applying the best management practices, incorporating sustainable feeds, reducing the
use of antibiotics and chemicals. The enhancement of interest in establishing sustainable wild
29
fisheries and aquaculture management also sets a roadmap to a sustainable fishing sector around
the globe that will help provide food as well as preserve marine resources in future. In an effort
to balance the need for a food source that is universally enjoyed as well as the need to protect our
marine environment, this dual effort is most fulfilling.
Employing the tragedy of commons in the regulation of North Atlantic watersheds
Hardin’s essay in 1968 introduced an idea called The Tragedy of the Commons that
explores how people can overcome the problems of exhaustion of the stocks. This framework
shows the tragedy of the commons through Self-temptation and governance conflict, any time
numerous individuals use one common property. This issue is most essential in employing water
resources in the North Atlantic; the marine environment is in several countries with divergent
concerns on biological, economical, and historical aspects of seas. At different locations,
competition friendly activities including the fishers have over exploited to the extent that the fish
has reduced in number hence proving hazardous to the economic benefits of the communities
involved. Moreover, the contaminants from water used for agriculture as well as the industries,
and ranged plastic wastes affects the quality of water and therefore the sea life as well as the
health of the humans. Thus climate change also yields other sources of pressure such as shift in
distribution of species and Ocean acidification and the common pool resource problem is
therefore hard to manage. Therefore, the management should use the collaborative managerial
process that corresponds to Tragedy of the Commons. All these strategies should foster
consolidation of nation’s efforts to compile pioneers for the use of scientific data and include
advocates in the decision strategies. Nevertheless, if the measurement of responsibility is
encouraged, and the practice that affected North Atlantic marine ecosystems is continued and
regulated, the future and the present population might benefit.
30
Fisheries in the North Atlantic are the best example of the eventual tragedy of the shared
resource, where nations act in their self-interest and often for quick economic benefit.
Overfishing has reduced the population of species including cod and haddock and which have
barred fishing communities from carrying out their business as usual (Bjorndal et al., 2019). The
past focus on large harvests with little effective method of control has led to fish stock declines,
which then have negative impacts spreading up the chain and endangering species. This has
mainly been due to the fact that many countries did not provide a proper coordinated
management plan and legal architecture which has consequently led to this race of fishing where
countries take as much of resources without pegging into the aspect of consequences on
ecological balance. It points out that this competitiveness is not only bad for the survival of fish
stock but also poses a great risk for the coastal societies that rely on these fisheries. Solving this
issue presupposes the adoption of common stewardship systems like the formation of the
transboundary management bodies that involve the nations’ agents. Such bodies may be helpful
in the organization of cooperation between countries and encouragement of the use of
economically sustainable approaches in fisheries which take into consideration the conditions in
the sea and the needs of different fishing communities. Sustaining measures are needed to
maintain fishing activities sustainable and to promote the conservation of the marine habitats
related to performance of these resources concerning fishery culture.
Moreover, the polluted water in North Atlantic and due to which the necessity of
cooperation for the control over pollution from point sources as well from sea has emerged.
Nutrients, plastics and toxic contaminants are its major causes of water and marine life
pollutions; these indicators provide unambiguous signals that the environments and human are
connected. Effects of actions carried out in localized areas are highlighted on the general marine
31
ecosystem in the consequences of agricultural drainage and discharges from urban facilities.
Thus, it could be pointed out that the problem of protection of shared water bodies could be
addressed through cooperation. For instance, the Reduction of Pollution activities, Convention
for the Protection of the North-East Atlantic, etc. This is a standard Interpol style convention on
aiming to control and prevent sources of pollution from several countries of the region to the seas
and oceans. It is for this reason that perception of the Tragedy of the Commons in the awareness
of the North Atlantic water resource management is the approach to the required perspective of
an integrated plan for sustainable usage of the water resource management. This is can include
creation of awareness about proper disposal of wastes, advancement of good techniques on
farming and improvement on laws on sea pollution. It means that such cooperation is useful not
only in enhancing the biological and species production for the North Atlantic, but also in
creating chancing the future generations have in gaining the opportunities in the economic and
ecological values of the sea. It is imperative to conserve these so called common pool resources
in efforts to protecting species abundance and the societies that directly depend on the source.
