Abstract

Feeding the world’s growing population will depend to a large extent on irrigation, but the future of irrigation water supplies is increasingly constrained by growth in other sectors. Other challenges, including declining water quality, falling groundwater tables, and growing environmental demands for water further constrain water availability for irrigation. Moreover, globalization and trade liberalization will increasingly impact water use and food production. Some of these challenges will be mediated by what we label the new ABCs of the future of water and food security: Aquaculture, Biotechnology, and Climate Change. In order to address these old and new challenges, fundamental changes in water management are necessary. With the right reforms in water management, implementation of appropriate economic incentives and investments in water infrastructure and agricultural research, progress can be made toward solving these challenges.

For a full description of the model, see Rosegrant et al. (2002).

Water consumption refers to water withdrawn from a source and made unusable for reuse in the same basin through irrecoverable losses, including evapotranspiration, seepage to a saline sink or contamination (Gleick 1998).

Non-irrigation uses include water demand for domestic, industrial and livestock uses (Rosegrant et al. 2002).

According to WHO and UNICEF (2004), 1.1 billion people lack access to an improved water supply and 2.6 billion people lack access to improved sanitation worldwide.

Millennium Development Goal Number 7, Target 10: To halve by 2015 the proportion of people without sustainable access to safe drinking water and basic sanitation.
