Water resources under stress as economies and populations grow with 2.2 billion people lacking clean drinking water.
Increasing global water scarcity is fuelling more conflicts and contributing to instability, the United Nations warns in a new report, which says access to clean water is critical to promoting peace.
The UN World Water Development Report 2024, released on Friday, said 2.2 billion people worldwide haveĀ no access to clean drinking waterĀ and 3.5 billion people lack access to safely managed sanitation.
Girls and women are the first victims of a lack of water, said the report, published by the UN Educational, Scientific and Cultural Organization (UNESCO), especially in rural areas where they have the primary responsibility of collecting supplies.
Spending several hours a day on fetching water, coupled with a lack of safe sanitation, is a contributing factor to girls dropping out of school.
āWater shortages not only fan the flames of geopolitical tensions but also pose a threat to fundamental rights as a whole, for example, by considerably undermining the position of girls and women,ā UNESCO chief Audrey Azoulay said.
While the report did not examine specific current conflicts, Israel has severely restricted access to fresh, clean water during its war on Gaza.
UN agencies haveĀ long warnedĀ that not only are children and women at grave risk of thirst and starvation, but the lack of clean water also has disrupted medical treatment and hygiene.Ā
The lack of water security drives migration, and displaced people strain resources in locations where they settle. The report cited a study in Somalia that indicated a 200 percent increase in gender-based violence against a group of displaced people.
At least 10 percent of global migration is linked to water stress as the world faces a more erratic climate, the researchers found.
The report also said: āGlobal warming is projected to ā¦ further increase the frequency and severity of droughts and floods, with more wet and very dry weather and climate events.ā
Titled Water for Prosperity and Peace, the report found that roughly half of the worldās population is experiencing severe water scarcity with some areas lacking water almost year-round.
Much of the consequences are felt in poorer countries, which find it harder to adapt. The report estimated that it would cost $114bn annually to provide safe drinking water, sanitation and hygiene in 140 low- to middle-income countries.
Quentin Graft from Water Justice Hub, a UNESCO affiliate, told Al Jazeera: āItās not just a water problem for people in Syria. Itās not just a water problem for people in Sudan. ā¦ Itās a water problem for all of us because we grow our food with freshwater whether itās irrigated or whether itās rain-fed, and when you have climate change on top of an already existing water crisis, then we have an inability to feed ourselves.ā
While 153 countries share water resources, only 24 have signed onto cooperation agreements covering all of their shared water, UN chief Antonio Guterres said in a statement marking World Water Day on Friday.
More than 60 percent of all freshwater resources are shared by two or more countries, including major rivers like the Rhine and Danube in Europe, the Mekong in Asia, the Nile in Africa and the Amazon in South America, Sonja Koeppel, secretary of the UN Water Convention, told the Agence France-Presse news agency.
The convention was established in 1992 to help foster responsible joint management of water resources in Europe but opened up in 2016 to countries around the world. It currently has 52 state parties, mainly in Europe, Asia and Africa.
