Climate Change Could Deprive Volta Basin of Water Needed to Boost Energy and Food Production

July 19, 2013 — A new study released today finds that so much water may be lost in the Volta River Basin due to climate change that planned hydroelectric projects to boost energy and food production may only tread water in keeping up with actual demand. Some 24 million people in Ghana, Burkina Faso and four other neighboring countries depend on the Volta River and its tributaries as their principal source of water.

Specifically, the researchers with the International Water Management Institute (IWMI) and their partners concluded that the combined effects of higher temperatures and diminished rain could mean that by the year 2100, all of the current and planned hydroelectric projects in the basin would not even generate as much power as existing facilities do now. Meanwhile, there would only be enough water to meet about a third of irrigation demand.
