Investing in water for food: Insights from the comprehensive assessment of water management in agriculture
In many river basins, patterns of water withdrawals, deliveries, depletion, return flows, and reuse are prevalent. These cascading systems, often misunderstood, provide opportunities, but also threats to livelihoods and environment. Different ways of thinking about these cascading systems are req...

Water, food, livelihoods and environment: maintaining biodiversity in irrigated landscapes. Draft discussion paper
In its broadest sense, water productivity (WP) is the net return for a unit of water used. Improvement of water productivity aims at producing more food, income, better livelihoods and ecosystem services with less water. There is considerable scope for improving water productivity of crop, livest...

The Zhanghe Irrigation System (ZIS), in Central China, has drawn attention internationally because it managed to sustain its rice production in the face of a dramatic reallocation of water to cities, industries and hydropower uses. Ponds, the small reservoirs ubiquitous in the area, are hypothesi...
