This is the opening prognosis given in the Earthscan publication Water for Food, Water for Life: A Comprehensive Assessment of Water Management in Agriculture released today to coincide with World Water Day.
The Assessment, the first of its kind, brings together the work of over 700 specialists from hundreds of institutes around the world into the most comprehensive and authoritative assessment of water and food ever written, critically examining policies and practices of water use and development in the agricultural sector over the last 50 years.
Spearheaded by International Water Management Institute (IWMI), one of 15 CGIAR agricultural research centres striving to increase food production, increase rural incomes, and safeguard the environment, the report is co-sponsored by the Consultative Group on International Agricultural Research (CGIAR), FAO, the Ramsar Convention on Wetlands, and the Convention on Biological Diversity in a bid to find solutions to the challenge of balancing the water-food-environment needs
