Water scarcity is a major global problem affecting over 1.1 billion people who lack access to safe drinking water. It occurs when there is insufficient available water to meet water usage demands within a region. It is caused by both natural factors like drought as well as human factors such as pollution, overuse, and mismanagement of water resources. Many reports suggest that water scarcity is driven more by human factors associated with population growth, urbanization, and industrialization rather than purely physical availability of water. If not addressed, water scarcity could significantly impact livelihoods and food security around the world.
This document discusses the global water crisis, focusing on case studies in Sao Paulo, Cape Town, and India. It notes that 1.1 billion people lack access to clean water and outlines factors contributing to water shortages like poor infrastructure, pollution, and climate change. Case studies highlight multi-year droughts in Sao Paulo and Cape Town that have led to daily water rationing and the potential for "Day Zero" when Cape Town's taps run dry. India also faces shortages due to overextraction, pollution of water sources, and lack of proper planning. Solutions proposed include improved infrastructure, rainwater harvesting, wastewater recycling, and desalination.
Water scarcity is a growing problem in India due to rising population, overexploitation of resources, and poor management. The document discusses how India's growing population and economy are straining limited water supplies, with demand expected to exceed availability by 2025. It provides details on water scarcity specifically in Tamil Nadu, where less than 500 cubic meters of water is available per person annually and groundwater levels are falling dramatically. The key impacts of water scarcity mentioned are drought, crop failure, unemployment, and conflicts over access to water.
This document discusses water scarcity and ways to save water. It notes that only 0.007% of earth's water is readily accessible for drinking, yet the average American uses over 500 liters per day. Simple steps people can take to conserve water include shortening shower times, turning off faucets tightly, fixing leaks immediately, and using low-flow fixtures and water-efficient appliances. Adopting these small changes can help address the growing global water crisis.
Mijul Saxena's presentation discusses water scarcity, its causes, impacts, and solutions. The major causes of water scarcity discussed are deforestation, water pollution, climate change, global warming, inefficient water use, poor water management, and population growth. Impacts include lack of access to safe drinking water for many people, reduced agricultural yields, and water-borne diseases. Solutions proposed are proper water management, reducing water waste, rainwater harvesting, afforestation, and increasing awareness of conservation.
Water scarcity is a growing problem caused by population growth outpacing available fresh water resources. Only 2.5% of the world's water is fresh, with much locked away in glaciers or underground. Water scarcity occurs when demand from agriculture, cities, and the environment exceeds the available supply. To address this, solutions like water conservation, wastewater recycling, and improving irrigation must be implemented, otherwise water conflicts and health issues will continue to escalate.
Water scarcity is a major global challenge caused by uneven distribution of water resources and rising population. The problem stems from both physical water scarcity due to lack of water sources as well as economic scarcity from poor water management. As population and industrial use increase, stress on water resources grows. Solutions require improved conservation efforts like desalination as well as cooperation between countries on shared water resources. Without concerted global action, the water crisis threatens to worsen health, development and ecosystems.
The document discusses water scarcity and its causes. It notes that while water covers most of the Earth's surface, only 3% is freshwater and available water resources are being depleted.

Water scarcity occurs when there is insufficient available water to meet water demand. It can be due to either economic or physical factors. Economically, some populations lack access to safe water due to lack of resources or infrastructure, while physically, some areas simply do not have enough water to meet demand due to climate or geography. Water scarcity affects health, life, agriculture and causes diseases. It is estimated that one in four deaths under age 5 are due to water-related disease and 80% of illnesses are caused by unsafe water. Water scarcity also threatens one quarter of the global population and over 10% consume wastewater irrigated foods which can transmit disease.
The document summarizes key drivers of increasing global water demand and potential solutions to close the growing water gap. By 2050, world water demand is projected to increase by 60% due to factors like population growth, changing diets, increased food production and urbanization. Agriculture currently accounts for 70% of water withdrawals globally. Solutions discussed to help close the growing gap between supply and demand include increased wastewater reuse, further development of desalination technologies, improving irrigation efficiency, appropriate water pricing, integrated water governance and planning at the basin scale.
Global water crisis is a serious issue affecting many regions of the world. Over 1/3 of the global population lacks access to clean drinking water. Lack of access to sanitation is linked to poverty and disproportionately impacts developing countries. Rapid population growth and development are straining water resources in many places through overuse, pollution, and depletion of sources. Improving access to clean water and sanitation worldwide is critical for public health, but achieving universal access remains a challenge.
Fresh water scarcity is a growing problem, particularly in developing countries, due to increasing population and climate change factors like drought. It affects access to education, health, food, and contributes to poverty. In countries like Tanzania and Kenya, lack of infrastructure and sanitation leads to water-borne diseases. Solutions include reducing water usage, helping rural communities access clean water, and developing technologies like desalination. International cooperation via treaties and development goals also aims to address this critical issue.
This document provides information about environmental change and water scarcity. It discusses how only 3% of the world's water is freshwater, and this freshwater is distributed unevenly. It then covers several causes of water scarcity like climate change, population growth, and pollution. Various impacts of water scarcity are explained such as lack of access to drinking water, hunger, disease spread, and conflict over water resources. Solutions to water scarcity discussed include recycling water, improving farming practices, and supporting clean water initiatives. The document also contains country-specific information about water scarcity in India.
The document discusses water usage and conservation. It notes that only 0.007% of water on Earth is potable and that all living things require water. Billions of people lack access to clean water, resulting in millions of deaths each year from water-related diseases. While developed countries like Spain have expanded water infrastructure, conservation is still important given unequal water distribution and the costs of treatment. Small actions like fixing leaks, limiting shower time, and catching rain water can significantly reduce individual water usage.

WATER SHORTAGE ITS CAUSES, IMPACTS AND REMEDIAL MEASURESIN PAKISTANFarhan Hussain
with two thirds of the earths surface covered by water, it is evidently clear that water is one of the most important elements responsible for life on earth. It is not only vital for sustenance of life but equally essential for the socioeconomic development. The global fresh water shortage and food security issues related to teeming billions of population necessitated the shifting of fresh water from agriculture to other more pressing uses. The country is facing the worst ever crises of water shortage for last many years, as water available for any given use has become increasingly scarce.
Water resources include sources of water that are useful for human purposes like agriculture, industry, households, recreation and the environment. Nearly all human uses require fresh water, but only 3% of the Earth's water is fresh, and over two-thirds of that is frozen in glaciers and polar ice caps. The remaining fresh water is found as groundwater or above ground. Increasing water scarcity is caused by overuse, population growth, industrialization, deforestation, and mismanagement of water resources. Multi-purpose river projects provide irrigation water while also generating hydropower, enabling navigation, and supporting fisheries to help address increasing scarcity. Rainwater harvesting and water conservation methods like reducing waste are important for preserving
Water availability & use in india -an overviewIEI GSC
The document discusses water availability and use in India. It notes that India's annual renewable water resources per capita have declined from 5000 cubic meters in 1950 to 1200 cubic meters currently, putting the country in a state of water stress. Several factors contribute to India's water issues, including uneven spatial and temporal distribution of water resources, less storage availability, high external dependence, sub-optimal resource utilization, and increasing deterioration of water quality through pollution. Addressing India's water challenges will require improved management of the country's water resources.
Depletion of water resources is a serious problem that threatens human survival. India faces a major groundwater crisis as levels are falling rapidly due to increased population, excessive extraction by farmers, unrestrained urbanization, and pollution. Overpumping of groundwater is depleting aquifers faster than they can replenish. This lowers water tables, increases costs, and causes land subsidence. The government is taking initiatives like Clean Ganga Mission, Yamuna Action Plan, and promoting rainwater harvesting to conserve water resources, but more must be done to sustain India's water supply for future generations.
Rainwater harvesting is an important technique for water conservation and mitigating water scarcity issues around the world. It involves collecting rainwater from surfaces like rooftops and storing it for future use, which recharges groundwater supplies. The document discusses how population growth, urbanization, climate change and other factors are depleting water resources in many places. It then outlines various rainwater harvesting methods, components, benefits like reducing water demand and flooding, and some limitations. The conclusion emphasizes that rainwater harvesting is a sustainable solution for communities facing water scarcity issues.

Environment and Health Status in Urban and Rural IndiaGAURAV. H .TANDON
Rural and urban areas in India face significant issues with water access and sanitation. In rural areas, most people lack piped water access and must collect water from sources like open wells or hand pumps, often spending significant time fetching water. Water quality is also an issue, with problems like arsenic contamination affecting millions of people. Sanitation infrastructure is similarly lacking, with most rural Indians practicing open defecation. In urban areas, piped supplies are unreliable and many cities face severe water shortages. Water theft and leakage exacerbate the problems in urban water systems. Overall, access to clean drinking water and sanitation remains inadequate in both rural and urban India.
India, country that occupies the greater part of South Asia. With roughly one-sixth of the world’s total population, India is the second most populous country. Types of water resources Surface water Resources Groundwater Resources.
Management of water resources in India has been a challenge whose magnitude has risen manifolds over the past 50 years due to a variety of reasons, notably the rising demands and growing environmental degradation.
The document discusses several key issues related to water resources:
1) Freshwater supplies are limited, with only 1% of the world's water usable for human needs. Water is essential but overused in many areas, with over 1 billion people lacking access to clean water.
2) Water is critical for agriculture, industry, domestic use, and ecosystems. However, population growth, pollution, dams, and climate change are straining water supplies in many regions.
3) Sustainable water management is needed, including conservation, small-scale infrastructure, wastewater recycling, and pricing water at its real value to reduce waste. Without action, water shortages will severely impact over 4 billion people by 2050.
The document discusses the global and Indian water crisis. It notes that over 1 billion people lack access to safe water and that water scarcity will affect 2/3 of the world's population by 2025. In India, water availability is very low compared to global averages and many areas already experience severe water stress. The major challenges facing India are rapid population growth, overexploitation of groundwater, pollution of existing supplies, and poor management. Potential solutions discussed include conservation efforts, water recycling, desalination plants, water footprinting, and rainwater harvesting.
Water scarcity leads to reduced agricultural outputs as less water means lower crop and livestock yields, which threatens food security and increases reliance on imports. It also raises production costs and can cause political instability if food shortages occur. Long-term water scarcity may even result in mass migrations, famine, and conflicts over access to scarce water resources.
The document discusses global and India's freshwater situation. Globally, freshwater reserves are depleting rapidly due to population growth, inefficient use, and climate change. By 2025, many countries including India, China, and parts of Europe and Africa will face water scarcity. In India, traditional water reserves are under strain from increasing population, urbanization, and economic development. Improved national water management strategies are needed to integrate regional initiatives and ensure long-term sustainable water usage across sectors.

In India, groundwater is being depleted, surface water is polluted, and rainfall is being wasted. This puts pressure on India's population and economic growth. Some solutions proposed include investing in desalination plants, implementing water footprinting to improve conservation, harvesting rainwater, and increasing awareness through social media. However, addressing the water crisis requires consideration of cultural, educational, technological and scientific factors.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
ENVIRONMENT~ Renewable Energy Sources and their future prospects.tiwarimanvi3129
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
3. Introduction
• Water scarcity is the lack of fresh water resources to
meet water demand.
• It affects every continent and was listed in 2019 by
the World Economic Forum as one of the
largest global risks in terms of potential impact over
the next decade.
• The essence of global water scarcity is the geographic
and temporal mismatch between freshwater demand
and availability.
4. Supply & Demand
• The total amount of easily
accessible freshwater on Earth, in the
form of surface
water (rivers and lakes)
or groundwater), is 14.000 cubic
kilometers
• Of this total amount, 'just' 5.000
cubic kilometers are being used and
reused by humanity.
• Scarcity as a result of consumption
is caused primarily by the extensive
use of water in agriculture/livestock
breeding and industry.
5.
6. Physical & Economic scarcity
• Physical water scarcity results from inadequate
natural water resources to supply a region's
demand.
• Economic water scarcity results from poor
management of the sufficient available water
resources.
8. Effects on environment
• Increased salinity, nutrient pollution, and the loss
of floodplains and wetlands.
9. • Depletion of freshwater
resources
Groundwater
Glaciers
• More than half of the
Earth's wetlands have been
destroyed and have
disappeared.
• Climate change
10. Water Scarcity: India’s Silent Crisis
• According to a NITI Aayog report, India will run out
of ground water in the next 10 years. Close to 40
percent of India will not get access to drinking water
by 2030.

13. All eyes on Jal Shakti ministry as India's
water crisis deepens
• The solution is better conservation of water and
moving away from heavy reliance on
groundwater for agriculture.
• The centre should lower GST for rainwater
harvesting equipment.
• Giving tax breaks for wastewater and
incentivizing drip irrigation is also the need of the
hour.
• The government had also promised that it will
implement recycling 100 percent liquid waste.
