Producing enough food for one person for one day requires about 3000 litres of water. When compared to the 2-5 litres required for drinking, it is clear that water for food production is a critical issue as populations and wealth grow.
The trade-food-water nexus and virtual water are significant issues in water for food production. GWP recognises the importance of engaging with the agricultural sector and will call for informed multi-stakeholder negotiations to change the way decision makers think about water and agriculture. For example, the productivity of water must improve. Yesterday's irrigation technologies must be adapted and upgraded to meet tomorrow's needs. In addition, since 60 % of agriculture in developing countries is rain-fed, it is also important to emphasise rain-fed food production.
