Water issues in developing countries

{{Further|Water scarcity in Africa|Water scarcity in India}}

People need fresh water for survival, personal care, agriculture, industry, and commerce. The 2019 UN World Water Development report noted that about four billion people, representing nearly two-thirds of the world population, experience severe water scarcity during at least one month of the year.{{Cite web|url=https://unesdoc.unesco.org/ark:/48223/pf0000367276.locale=en|title=The United Nations world water development report 2019: Leaving no one behind, facts and figures.|website=UNESDOC|access-date=1 June 2019}} 50px Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by-sa/3.0/igo/ Attribution-ShareAlike 3.0 IGO (CC BY-SA 3.0 IGO)] license. With rising demand, the quality and supply of water have diminished.{{Cite book|title=Principles of Water Quality Control|last=Tebbutt|first=T.|publisher=Elsevier Ltd.|year=1998}}

Water use has been increasing worldwide by about 1% per year since the 1980s. Global water demand is expected to continue increasing at a similar rate until 2050, accounting for an increase of 20–30% above 2019 usage levels. The steady rise in use has principally been led by surging demand in developing countries and emerging economies. Per capita water use in the majority of these countries remains far below water use in developed countries—they are merely catching up.

Agriculture (including irrigation, livestock, and aquaculture) is by far the largest water consumer, accounting for 69% of annual water withdrawals globally. Agriculture's share of total water use is likely to fall in comparison with other sectors, but it will remain the largest user overall in terms of both withdrawal and consumption. Industry (including power generation) accounts for 19% and households for 12%.

After accounting for availability or access, water quality can reduce the amount of water for consumption, sanitation, agriculture, and industrial purposes.{{Cite web|title=Water quality and food safety & COVID-19; Land & Water; Food and Agriculture Organization of the United Nations; Land & Water; Food and Agriculture Organization of the United Nations|url=http://www.fao.org/land-water/overview/covid19/qualitysafety/en/|access-date=12 April 2021|website=www.fao.org}} Acceptable water quality depends on its intended purpose: water that is unfit for human consumption could still be used in industrial or agriculture applications. Parts of the world are experiencing extensive deterioration of water quality, rendering the water unfit for agricultural or industrial use. For example, in China, 54% of the Hai River basin surface water is so polluted that it is considered un-usable.{{Cite journal|last1=Ding|first1=Yuekui|last2=Shan|first2=Baoqing|last3=Zhao|first3=Yu|date=2015–2019|title=Assessment of River Habitat Quality in the Hai River Basin, Northern China|journal=International Journal of Environmental Research and Public Health|volume=12|issue=9|pages=11699–11717|doi=10.3390/ijerph120911699|issn=1661-7827|pmc=4586701|pmid=26393628|doi-access=free}}

Safe water is defined as potable water that will not harm the consumer.{{Cite web|title=Can you define safe water?|url=https://www.usgs.gov/media/audio/can-you-define-safe-water#:~:text=define%20safe%20water?-,Safe%20water%20means%20water%20that%20will%20not%20harm%20you%20if,low%20concentrations%20of%20harmful%20contaminants.|access-date=29 November 2020|website=www.usgs.gov| date=19 August 2008 }} It is one of the eight Millennium Development Goals: between 1990 and 2015 to "reduce by half the proportion of the population without sustainable access to safe drinking water and basic sanitation." Even having access to an ‘improved water source’ does not guarantee the water's quality, as it could lack proper treatment and become contaminated during transport or home storage.{{cite book |author=Bouman, Dick, Novalia, Wikke, Willemsen, Peter Hiemstra, Jannie Willemsen |title=Smart disinfection solutions : examples of small-scale disinfection products for safe drinking water |publisher=KIT Publishers |year=2010 |isbn=978-9460221019 |location=Amsterdam}} A study by the World Health Organization (WHO) found that estimates of safe water could be overestimated if accounting for water quality, especially if the water sources were poorly maintained.{{Cite journal|last1=Bain|first1=Rob E.

Polluted drinking water can lead to debilitating or deadly water-borne diseases, such as fever, cholera, dysentery, diarrhea and others. UNICEF cites fecal contamination and high levels of naturally occurring arsenic and fluoride as two of the world's major water quality concerns. Approximately 71% of all illnesses in developing countries are caused by poor water and sanitation conditions.{{cite web|url=http://thewaterproject.org/water_scarcity_2.asp#phys|title=The Lack of clean water: Root cause of many problems|date=18 March 2012}} Worldwide, contaminated water leads to 4,000 diarrhea deaths a day in children under 5.{{cite web|last=UNICEF|title=Water, Sanitation and Hygiene|url=http://www.unicef.org/wash/index_water_quality.html|publisher=UNICEF}}File:ChildWithWellPump.JPG

However, gaps in wastewater treatment (the amount of wastewater to be treated is greater than the amount that is actually treated) represent the most significant contribution to water pollution and water quality deterioration. In the majority of the developing world, most of the collected wastewater is returned to surface waters directly without treatment, reducing the water's quality.{{cite journal|last=MARKANDYA|first=ANIL|title=WATER QUALITY ISSUES IN DEVELOPING COUNTRIES| date=March 2004 |url=http://policydialogue.org/files/publications/03_Water_quality.pdf}} In China, only 38% of China's urban wastewater is treated, and although 91% of China's industrial waste water is treated, it still releases extensive toxins into the water supply.{{cite web |last=The Barilla Group, The Coca-Cola Company, The International Finance Corporation, McKinsey & Company, Nestlé S.A., New Holland Agriculture, SABMiller plc, Standard Chartered Bank, and Syngenta AG. |title=Charting Our Water Future {{!}} Economic frameworks to inform decision-making |url=http://www.2030waterresourcesgroup.com/water_full/Charting_Our_Water_Future_Final.pdf}}

The amount of possible wastewater treatment can also be compromised by the networks required to bring the wastewater to the treatment plants. It is estimated that 15% of China's wastewater treatment facilities are not being used to capacity due to a limited pipe network to collect and transport wastewater. In São Paulo, Brazil, a lack of sanitation infrastructure results in the pollution of the majority of its water supply and forces the city to import over 50% of its water from outside watersheds. Polluted water increases a developing country's operating costs, as lower quality water is more expensive to treat. In Brazil, polluted water from the Guarapiranga Reservoir costs $0.43 per m³ to treat to usable quality, compared to only $0.10 per m³ for water coming from the Cantareira Mountains.

To address water scarcity, organizations have focused on increasing the supply of fresh water, mitigating its demand, and enabling reuse and recycling.{{Cite book |last1=Woltersdorf |first1=L. |url=https://www.sciencedirect.com/science/article/pii/S0921344916303445 |title=Resources, Conservation and Recycling |last2=Zimmermann |first2=M. |last3=Deffnera |first3=J. |last4=Gerlachb |first4=M. |last5=Liehra |first5=S. |date=January 2018 |volume=128 |pages=382–393 |publisher=Elsevier Ltd.|doi=10.1016/j.resconrec.2016.11.019 }}

According to the WHO, consistent access to a safe drinking-water supply is attainable by establishing a system of WSPs, or Water Safety Plans, which determine the quality of water supply's to ensure they are safe for consumption.{{Cite web|title=WHO {{!}} Water safety planning|url=http://www.who.int/water_sanitation_health/water-quality/safety-planning/en/|archive-url=https://web.archive.org/web/20160831031500/http://www.who.int/water_sanitation_health/water-quality/safety-planning/en/|url-status=dead|archive-date=31 August 2016|access-date=29 November 2020|website=WHO}} The Water Safety Plan Manual, published in 2009 by the WHO and the International Water Association, offers guidance to water utilities (or similar entities) as they develop WSPs. This manual provides information to help water utilities assess their water system, develop monitoring systems and procedures, manage their plan, carry out periodic review of the WSP, and to review the WSP following an incident. The WSP manual also includes three case studies drawn from WSP initiatives in three countries/regions.{{cite web|title=Water Safety Plan Manual: Step-by-step risk management for drinking water suppliers|url=http://whqlibdoc.who.int/publications/2009/9789241562638_eng_print.pdf|publisher=World Health Organization and International Water Association|access-date=26 March 2012}}

{{Main|Reclaimed water}}

Utilizing wastewater from one process to be used in another process where lower-quality water is acceptable is one way to reduce the amount of wastewater pollution and simultaneously increase water supplies. Recycling and reuse techniques can include the reuse and treatment of wastewater from industrial plant wastewater or treated service water (from mining) for use in lower quality uses. Similarly, wastewater can be re-used in commercial buildings (e.g. in toilets) or for industrial applications (e.g. for industrial cooling).

{{Further|Water pollution}}

Despite the clear benefits of improving water sources (a WHO study showed a potential economic benefit of $3–34 USD for every US$1 invested), aid for water improvements have declined from 1998 to 2008 and generally is less than is needed to meet the MDG targets. In addition to increasing funding resources towards water quality, many development plans stress the importance of improving policy, market and governance structures to implement, monitor and enforce water quality improvements.{{cite book|title=GLAAS 2010: UN-Water Global Annual Assessment of Sanitation and Drink-Water|year=2010|publisher=World Health Organization, UN-Water|isbn=978-92-4-159935-1}}

Reducing the amount of pollution emitted from both point and non-point sources represents a direct method to address the source of water quality challenges. Pollution reduction represents a more direct and low-cost method to improve water quality, compared to costly and extensive wastewater treatment improvements.

Various policy measures and infrastructure systems could help limit water pollution in developing countries. These include:{{cite journal |last=Islam |first=Mohammmed Nasimul |date=8 September 2010 |title=Challenges for Sustainable Water Quality Improvement in Developing Countries |url=http://www.worldwaterweek.org/documents/WWW_PDF/2010/wednesday/T3/1_AM_MN_Islam.pdf |journal=International Water Week, Stockholm Sweden}}

1. Improved management, enforcement and regulation for pre-treatment of industrial and agricultural waste, including charges for pollution
2. Policies to reduce agricultural run-off or subsidies to improve the quality and reduce the quantity needed of water polluting agricultural inputs (e.g. fertilizers)
3. Limiting water abstraction during critical low flow periods to limit the concentration of pollutants
4. Strong and consistent political leadership on water
5. Land planning (e.g. locating industrial sites outside the city)

{{Main|Portable water purification|Self-supply of water and sanitation|Water treatment}}

Water treatment technologies can convert non-freshwater to freshwater by removing pollutants. Much of water's physical pollution includes organisms, metals, acids, sediment, chemicals, waste, and nutrients. Water can be treated and purified into freshwater with limited or no constituents through certain processes. The processes involved in removing the contaminants include physical processes such as settling and filtration, chemical processes such as disinfection and coagulation, and biological processes such as slow sand filtration.{{cn|date=April 2023}}

A variety of innovations exist to effectively treat water at the point of use for human consumption. Studies have shown treatment to point of use sources reduces child mortality by diarrhea by 29%.{{Cite journal|last1=Black|first1=Robert|last2=Fontaine|first2=Olivier|last3=Lamberti|first3=Laura|last4=Bhan|first4=Maharaj|last5=Huicho|first5=Luis|last6=El Arifeen|first6=Shams|last7=Masanja|first7=Honorati|last8=Walker|first8=Christa Fischer|last9=Mengestu|first9=Tigest Ketsela|last10=Pearson|first10=Luwei|last11=Young|first11=Mark|title=Drivers of the reduction in childhood diarrhea mortality 1980–2015 and interventions to eliminate preventable diarrhea deaths by 2030|journal=Journal of Global Health|year=2019|volume=9|issue=2|pages=020801|doi=10.7189/jogh.09.020801|issn=2047-2978|pmc=6815873|pmid=31673345}} Home water treatments are also a part of the United Nations' Millennium Development Goals, with the goal of providing both clean water supply and sewage connection in homes. Although these interventions have been evaluated by the United Nations, various challenges may reduce the effectiveness of home treatment solutions, such as low education, low-dedication to repair, replacement, and maintenance, or local repair services or parts are unavailable.

Current point of use and small scale treatment technologies include:

• NaDCC, sodium dichloroisocyanurate
• Boiling water
• Solar disinfection (SODIS)
• Chlorine

Central Asia Water and Energy Program (CAWEP) is a World Bank, European Union, Swiss & UK funded program to organize Central Asian governments on common water resources management through regional organizations, like the International Fund for Saving the Aral Sea (IFAS). The program focuses on three issues: water security, energy security and energy-water linkages. It aims to foster balanced communications between Central Asian countries to achieve a regional goal, water and energy security. To ensure their goal, the program works closely with governments, civil and national organizations.{{cite web|title=Central Asia Water & Energy Program|url=https://www.worldbank.org/en/region/eca/brief/cawep|website=World Bank}}

Most recently, the program helped organize The Global Disruptive Tech Challenge: Restoring Landscapes in the Aral Sea Region. This competition was created to encourage bright minds to come up with revolutionary solutions for land degradation and desertification in the Aral Sea Region, which used to be home to one of the largest lakes in the world and has since been reduced near to nothing. There were several winning projects that centered around agriculture and land management, sustainable forestry, socio-economic development and globally expanding people knowledge and access to information on the issue.{{Cite web|title=Innovative Restoration Plans for Aral Sea Region Announced at Global Disruptive Tech Challenge 2021|url=https://www.worldbank.org/en/news/press-release/2021/04/09/innovative-restoration-plans-for-aral-sea-region-announced-at-global-disruptive-tech-challenge-2021|access-date=2 May 2021|website=World Bank|language=en}}

Aimed at achieving the United Nation's Sustainable Development Goal 6, Sanitation and Water for All (SWA) was established as a platform for partnerships between governments, civil society, the private sector, UN agencies, research and learning institutions, and the philanthropic community.

{{Main|Water supply and sanitation in India}}

India's growing population is putting a strain on the country's preciously scarce water resources. According to The World Bank, the population of India as of 2019 was roughly 1,366,417,750 people.{{Cite web|title=Population, total {{!}} Data|url=https://data.worldbank.org/indicator/SP.POP.TOTL|access-date=2 May 2021|website=data.worldbank.org}} Although this number has increased since then, India's population count has made it the second-most populated country in the world, following close behind the first most populated country, China.{{Cite web|title=Population by Country (2021) – Worldometer|url=https://www.worldometers.info/world-population/population-by-country/|access-date=2 May 2021|website=www.worldometers.info|language=en}} The country is classified as "water stressed" with a water availability of 1,000–1,700 m³/person/year.{{cite web|url=http://www.unep.org/dewa/vitalwater/index.html|title=Vital Water Index|access-date=24 March 2012}} 21% of countries' diseases are related to water.{{Cite web|last=Snyder|first=Shannyn|title=WATER IN CRISIS – INDIA|url=https://thewaterproject.org/water-crisis/water-in-crisis-india|website=The Water Project}} Retrieved 22 November 2020. In 2008, 88% of the population had access and was using improved drinking water sources.{{cite web|url=http://www.unicef.org/infobycountry/india_statistics.html|title=India|work=UNICEF |access-date=23 March 2012}} However, "Improved drinking water source" is an ambiguous term, ranging in meaning from fully treated and 24-hour availability to merely being piped through the city and sporadically available.{{Cite news|last=Sengupta|first=Somini|url=https://www.nytimes.com/2006/09/29/world/asia/29water.html|title=In Teeming India, Water Crisis Means Dry Pipes and Foul Sludge|date=29 September 2006|work=The New York Times|access-date=1 June 2019|language=en-US|issn=0362-4331}} This is in part due to large inefficiencies in the water infrastructure in which up to 40% of water leaks out.

In UNICEF's 2008 report, only 31% of the population had access and used improved sanitation facilities. A little more than half of the 16 million residents of New Delhi, the capital city, have access to this service. Every day, 950 million gallons of sewage flows from New Delhi into the Yamuna River without any significant forms of treatment. This river bubbles with methane and was found to have a fecal coliform count 10,000 times the safe limit for bathing.

The inequality between urban and rural areas is significant. In rural areas, 84% can access safe water while only 21% for sanitation. In contrast, 96% of people in urban areas have access to water sources and sanitation which meet satisfying quality. Additionally, there are not enough wastewater treatment facilities to dispose of wastewater discharged from the growing population. By 2050 half of India's population will account for urban areas and will face serious water problems.{{Cite web|title=India's rampant urban water issues and challenges|url=https://www.teriin.org/article/indias-rampant-urban-water-issues-and-challenges|access-date=12 November 2020|website=www.teriin.org|language=en}}

Surface water contamination, due to lack of sewage treatment and industrial discharge, makes groundwater increasingly exploited in many regions of India. This is aggravated by heavily subsidized energy costs for agriculture practices that make up roughly 80% of India's water resource demand.{{cite web|url=http://www.unwater.org/statistics_KWIP.html|title=Key Water Indicator Portal-Water Statistics|access-date=23 March 2012}}

In India, 80% of the health issues come from waterborne diseases.{{cite web|url=http://www.globalwaterforum.org/2012/03/05/special-essay-the-ganges-eternally-pure/|title=Special Essay: The Ganga – Eternally pure?|last=Wohl|first=Ellen|publisher=Global Water Forum}} Part of this challenge includes addressing the pollution of the Ganges (Ganga) river, which is home to about 400 million people.{{cite web|url=http://www.treehugger.com/clean-water/world-bank-approves-1-billion-for-ganges-river-cleanup.html|title=World Bank Approves $1 Billion For Ganges River Cleanup|last=McDermott|first=Mat|publisher=Treehugger}} The river receives about over 1.3 billion litres of domestic waste, along with 260 million litres of industrial waste, run off from 6 million tons of fertilizers and 9,000 tons of pesticides used in agriculture, thousands of animal carcasses and several hundred human corpses released into the river every day for spiritual rebirth. Two-thirds of this waste is released into the river untreated.

{{Main|Water supply and sanitation in Kenya}}

Kenya, a country of 50 million population, struggles with a staggering population growth rate of 2.28% per year.{{Cite web|title=Kenya Population (2020) – Worldometer|url=https://www.worldometers.info/world-population/kenya-population/|access-date=12 November 2020|website=www.worldometers.info|language=en}} This high population growth rate pushes Kenya's natural resources to the brink of total depletion. 32% of the population don't have access to improved water sources whereas 48% cannot access basic sanitation systems.{{Cite web|title=Kenya's Water Crisis – Kenya's Water In 2020|url=https://water.org/our-impact/where-we-work/kenya/|access-date=12 November 2020|website=Water.org}} Much of the country has a severely arid climate, with a few areas enjoying rain and access to water resources. Deforestation and soil degradation have polluted surface water, and the government does not have the capacity to develop water treatment or distribution systems, leaving the vast majority of the country without access to water. This has exacerbated gender politics, as 74% of women must spend an average of 8 hours per day securing water for their families.{{cite web|url=http://thewaterproject.org/water-in-crisis-kenya.asp|title=Kenya|access-date=28 March 2012}}

Low income has worsened the situation. It is estimated that 66% of the total population lives to earn less than $3.20 per day. Despite its poor quality and unreliableness, costs for water in local areas are 9 times higher than that of safe water in urban areas. This regional inequality makes people in rural areas difficult to obtain water on a daily basis. Furthermore, even in urban areas, which are equipped with piped water systems, it's hard to produce a reliable constant flow of water. Practical solutions are needed in the entire country. The Sand dam is one of the decentralized rainwater harvesting infrastructures to deal with this unbalanced water distribution.{{Cite journal|date=1 May 2021|title=Assessment of water presence and use at sand dams in Kenya|url=https://www.sciencedirect.com/science/article/abs/pii/S0140196321000380|journal=Journal of Arid Environments|language=en|volume=188|pages=104472|doi=10.1016/j.jaridenv.2021.104472|issn=0140-1963|last1=Neufeld|first1=Doug Graber|last2=Muli|first2=Joseph|last3=Muendo|first3=Bernard|last4=Kanyari|first4=James|bibcode=2021JArEn.188j4472N|s2cid=233539040|url-access=subscription}} This low-cost infrastructure has a simple and understandable structure, conserving surplus water for later use, increasing efficiency and rural regions' water access by saving people's time to gathering water on a long road.{{Cite web|title=How Sand Dams Work|url=https://thewaterproject.org/sand-dams|access-date=1 May 2021|website=The Water Project|language=en}} There are already about 1,800 sand dams in Kitui County.{{Cite web|title=Ensuring resilience through community sand dams in Kenya – GRIPP {{!}} IWMI Project Site|url=https://gripp.iwmi.org/natural-infrastructure/water-storage/ensuring-resilience-through-community-sand-dams-in-kenya/|access-date=1 May 2021|website=Groundwater Solutions Initiative for Policy and Practice (GRIPP)|language=en-US}}

The growing population and stagnant economy have exacerbated urban, suburban, and rural poverty. It also has aggravated the country's lack of access to clean drinking water which leaves most of the non-elite population suffering from disease. Around 240 million people suffer from schistosomiasis which occurs because of parasitic worms that may be contracted through drinking infested waters.{{Cite web|title=Water|url=https://www.afro.who.int/health-topics/water|access-date=23 October 2021|website=WHO {{!}} Regional Office for Africa|language=en}} This leads to the crippling of Kenya's human capital.{{cite web|url=http://www.ke.undp.org/index.php/programmes/poverty-reduction|title=Poverty Reduction|date=28 March 2012}}

Private water companies have taken up the slack from Kenya's government, but the Kenyan government prevents them from moving into the poverty-stricken areas to avoid profiteering activities. Unfortunately, since Kenya's government also refuses to provide services, this leaves the disenfranchised with no options for obtaining clean water.
