An unprecedented rise in the demand for food, rapid urbanization and climate change are significantly threatening global water supplies, according to a United Nations report released today, which stresses that a radical new approach to managing this essential resource is needed to be able to sustain future consumption levels.
In addition, climate change will also have a growing impact on water resources as it alters rainfall patterns and soil humidity, melts glaciers and causes water-related disasters such as floods and droughts, which impact food production. The report estimates that by 2070, this impact will affect up to 44 million people all over the world.
The Chair of UN-Water, Michel Jarraud, stressed that “a collective response by the whole international community” will be needed to tackle the issue. The report emphasizes that without drastic action, water pressure will exacerbate economic disparities within and between countries, hitting the poor particularly hard.
“Unless water becomes a more central consideration in development planning, billions of people, mostly in developing countries, could face reduced livelihoods and life chances,” UNESCO said in a news release. “Better governance of water resources is required, including investments in infrastructure from both private and public sectors.”
The report also shows that despite projected increases in water demand, there are still nearly one billion people without such access, and this number is growing in cities.
According to the report, sanitation infrastructure is not keeping pace with the world’s urban population, and more than 80 per cent of the world’s waste water is neither collected nor treated.
