Moreover, given that water supply growth is limited but domestic and industrial water demand are growing rapidly, a significant share of the additional water for domestic and industrial uses will come from the irrigation sector. This transfer will lead to a substantial increase in water scarcity for irrigation, giving rise to more conflicts, in the future, between water for food and water for other uses in many parts of the world. Policy reform including agricultural research and management in rainfed areas and changes in the management of irrigation and water supplies are therefore urgently needed to ensure sustainable water access and affordable food prices.
