Does International Cereal Trade Save Water? The Impact of Virtual Water Trade on Global Water Use
(2004) de Fraiture, Charlotte; Cai, Ximing; Amarasinghe, Upali A.; Rosegrant, Mark; Molden, David
"Virtual water refers to the volume of water used to produce agricultural commodities. When these commodities enter the world market, trade in virtual water takes place. This report argues that the role of virtual water trade in global water use is modest, since most trade takes place, and will continue to take place, between water abundant countries."
Macro Policies and Investment Priorities for Irrigated Agriculture in Vietnam
(2005) Barker, Randolph; Ringler, Claudia; Minh Tien, Nguyen; Rosegrant, Mark
"This report discusses the experience of the recent past and future prospects of the agriculture sector. We examine the trends and changes in agricultural taxation and expenditures noting the constraints to agricultural growth related to policies in the nonagriculture as well as the agriculture sector. We focus, in particular, on irrigation, which has accounted for over half of agricultural expenditure over the past decade and which has been a major contributor to both rapid growth in exports and agricultural employment."
Modeling Water Resources Management at the Basin Level: Review and Future Directions
(1999) McKinney, Daene C.; Cai, Ximing; Rosegrant, Mark; Ringler, Claudia; Scott, Christopher
"The world is facing severe and growing challenges in maintaining water quality and meeting the rapidly growing demand for water resources. New sources of water are increasingly expensive to exploit, limiting the potential for expansion of new water supplies. Water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth."
Optional Water Development Strategies for the Yellow River Basin: Balancing Agricultural and Ecological Water Demands
(2003) Cai, Ximing; Rosegrant, Mark
"The Yellow River basin is of utmost importance for China in food production, natural resources management, and socioeconomic development. Water withdrawals for agriculture, industry and households in the past decade have seriously depleted ecological water requirements in the basin, of which agriculture is the major player. This paper presents a modeling scenario analysis of some water development strategies to harmonize water withdrawal demand and ecological water demand in the Yellow River Basin through water saving and inter-basin water transfer. A global water and food analysis model, IMPACT-WATER, including the Yellow River Basin as one of the modeling units, is applied for the analysis. It is found that there is little space for resolving the conflict between agriculture water demand and ecological water demand in the basin, if the current practices of water use continue. Strong tradeoffs exist between irrigation water use and ecological water use and the tradeoffs will become more intensive in future years with population growth, urbanization and industrial development, and food demand increases in the YRB. Substantial pressure exists in the basin to improve water demand control and water saving, and for consideration of other measures including inter-basin water transfer through the South-North-Water Transfer (SNWT) project. Scenario analysis in this paper concludes that increasing water use efficiency to a feasible level first and then supplementary water availability by the SNWT may provide a solution to water management of the YRB in the next 25 years."
