For Immediate Release
Water Scarcity Looms as Population, Temperature Rise
population growth, climate change, and pollution restrict the amount of
water available relative to demand. In 2008, 1.4 billion people lived
in "closed basins"-regions where existing water cannot meet the
agricultural, municipal, and environmental needs for all. This number
is expected to grow to 1.8 billion by 2025.
According to the latest Vital Signs snapshot of water scarcity trends:
- Population growth is a major driver of water scarcity at the
regional and global levels. Urbanization and rising incomes-two trends
prominent in rapidly developing countries such as China, India, and
Brazil-also contribute to increased domestic and industrial demand for
- Several major rivers, including the Indus, Rio Grande,
Colorado, Murray-Darling, and Yellow, no longer reach the sea
year-round as a growing share of their waters are claimed for various
- Diets heavy in livestock are water intensive because of
the huge quantities of water required for livestock production.
Similarly, fossil fuel production requires many times more water than
renewable energy sources do.
This new water scarcity update includes the latest figures on water
consumption by energy type and water dependence of selected countries.
