DCG's factsheet on water harvesting
Ensuring food security for people in the drylands is a challenge. Lack of soil fertility and water stress are two main factors limit agricultural production critical to food security. Rainfed agriculture which is common in the drylands (from 300mm rainfall per year) is highly vulnerable to climate change, causing rainfall to be more scarce and erratic. Harvesting of rain and runoff water, and effective management of water are ancient concerns of populations whose expertise in this area is important. But traditional responses are being challenged by the pace and unpredictability of the changes. The identification and study of these methods, their improvement and exchange between regions are significant steps in realizing their full potential, especially for small-scale farmers. Water harvesting and conservation are becoming two essential priorities of any national and local program aiming at ensuring food security in the drylands. The Drylands Coordination Group provides its research results for the policies to be are as effective as possible.
