Rainwater harvesting agriculture: an integrated system for water management on rainfed land in China's semiarid areas

Article Abstract:

An evaluation is presented on rainwater harvesting agriculture in China's Gansu province, which involves the collection and storage of precipitation that would otherwise have become runoff. Although this process has been successful for small farms, many technological, political, economic and social issues need to be addressed before it can be used on a larger scale.
