With water scarcity emerging as a global concern, we simply cannot continue the water-intense methods of the past. Yet, as human numbers increase, more food needs to be produced with the same - or shrinking - land. This calls for smarter, thriftier ways of using freshwater and increasing water's productivity in agriculture, without damaging the environment, or undermining food security, jobs or health.
The CGIAR Challenge Program on Water and Food (CPWF) has brought together dozens of researchers, policy makers and local communities in Africa, Asia and South America to look for practical solutions through action research. We travel to eight of its benchmark river basins to find out what has been accomplished - and what remains to be done -- to grow more food with less water.
Droughts, floods and environmental degradation have caused much concern among the ten African countries that share the River Nile. As they search for ways to minimise damage, researchers are focusing on people, livestock and the land near the source of this mighty river. Everybody needs to manage more with less water, and old habits have to change.
