Communities across the globe can build resilience to climate change by re-inventing old water storage strategies and investing in new ones, according to a new book by the International Water Management Institute.
From the Center for International Forestry Research (link below):
“Combining water storage and savings options often is the most effective way to tackle increasing weather variability, the researchers say. But communities need to weigh trade-offs and be wary of unintended consequences.
“’Water is a scarce resource, but the reality in many river basins across the world is that it also is an inefficiently under-used resource that can be better utilized to offset climate change and ensure food security,’ says Jeremy Bird, IWMI’s director-general. ‘But the challenge is complex and solutions must be tailored to local situations.’
“For example, in Rajasthan, India—dubbed the Great Indian Desert—the state government is responding to an inefficient canal system by subsidizing farmers to make farm ponds. The ponds are filled from the Indira Gandhi canal system once a month.
“Farmers can then draw water as needed. The storage strategy can be combined with water-saving technologies such as micro-irrigation. ‘Combining water storage and savings options is one of the most practical, immediate and cost-effective ways to respond to climate-induced water scarcity,’ says Vladimir Smakhtin, IWMI’s theme leader on water availability and access.
“The research was supported by Climate Change, Agriculture and Food Security (CCAFS) and Water Land and Ecosystems (WLE) research programs of the Consultative Group on International Agricultural Research (CGIAR).”
