News Water Storage in an Era of Climate Change: Addressing the Challenge of Increasing Rainfall Variability

Against a backdrop of extreme weather wreaking havoc around the world, a new report warns that increasingly erratic rainfall related to climate change will pose a major threat to food security and economic growth, especially in Africa and Asia, requiring increased investment in diverse forms of water storage as an effective remedy.

 "Millions of farmers in communities dependent on rainfed agriculture are at risk from decreasing and erratic availability of water," said Colin Chartres, director general of the Sri Lanka-based International Water Management Institute (IWMI), which released the report to coincide with World Water Week 2010 in Stockholm. "Climate change will hit these people hard, so we have to invest heavily and quickly in adaptation."

The report argues against overreliance on single solutions like big dams, proposing instead an integrated approach that combines large- and small-scale storage options, including the use of water from natural wetlands, water stored in the soil, groundwater beneath the earth’s surface and water collected in ponds, tanks and reservoirs.
