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.
The UN World Water Development Report, which will be launched at the World Water Forum
in Marseille, estimates that there will be a 70 per cent increase in demand for food by the year 2050, leading to a 19 per
cent surge in water used for agriculture. At the moment, 70 per cent of freshwater is already being used for agricultural
“Freshwater is not being used sustainably,
according to needs and demands,” states the Director-General of the UN Educational, Scientific and Cultural Organization
(UNESCO), Irina Bokova, in the report’s foreword. “Accurate information remains disparate, and management is fragmented.
In this context, the future is increasingly uncertain and risks are set to deepen.”
The report, entitled “Managing Water under Uncertainty and Risk,” notes
that to respond to growing demand, countries have tapped into underground water sources, with water extraction tripling over
the past 50 years. However, in some underground basins, water cannot be replenished and is now at critically low 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.
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.
“We have much to do before all people have the access to the water and sanitation they need
to lead lives of dignity and well-being,” said Secretary-General Ban Ki-moon in a video message to the World Water Forum.
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.
