| Decades of Soviet rule have left a heritage of environmental and social problems in Central Asia. The demise of an entire ecosystem at unprecedented pace, the "Aral Sea Syndrome", is the most prominent of the undesired outcomes of the focus on agricultural production that has dominated land and resource use and continues till today. The international outcry over this ecological crisis has delegated other – and maybe more urgent – problems to a second pane. Rural livelihoods are rapidly deteriorating, unemployment is high, and rural poverty widespread. Ecological aspects, although strongly affecting everyday life in rural areas – such as water and soil salinity and environmental pollution – are not the fore most concern to the local population, as the... |

| Increasing competition for water across sectors increases the importance of the river basin as the appropriate unit of analysis to address the challenges facing water resources management; and modeling at this scale can provide essential information for policymakers in their resource allocation decisions. This paper introduces an integrated economic-hydrologic modeling framework that accounts for the interactions between water allocation, farmer input choice, agricultural productivity, nonagricultural water demand, and resource degradation in order to estimate the social and economic gains from improvement in the allocation and efficiency of water use. The model is applied to the Maipo River Basin in Chile. Economic benefits to water use are evaluated for... |

| Limited water resources are increasingly constrained by growing water demand for agricultural, industrial, and domestic uses, which in turn exacerbates environmental degradation and water-quality problems. This research report develops and applies a comprehensive decision-support tool for examining these issues at the river-basin level—the natural unit of analysis for water allocation and use. Authors Ximing Cai, Claudia Ringler, and Mark Rosegrant develop an integrated hydrologic– economic river-basin model, simulating water flows, salinity balances, and crop growth under water-allocation scenarios. One of the main advantages of the model is its ability to reflect the dynamic interactions of essential hydrologic, agronomic, and economic components and to... |

| Sustainable irrigation water management should simultaneously achieve two objectives: sustaining irrigated agriculture for food security and preserving the associated natural environment. A stable relationship should be maintained between these two objectives now and in the future, while potential conflicts between these objectives should be mitigated through appropriate irrigation practices. Lessons learned from unsustainable water management practices around the world demonstrate the necessity—and growing urgency—of applying sustainability principles to water management in river basins where irrigation is a major factor. This paper presents the operational concepts and analytical framework for sustainability analysis of irrigation water management in... |
