FAO (August 23, 2011) | The vulnerability of rain-dependent food production systems and the people who depend on them has been brought into stark relief by the situation in East Africa. While the challenges of finding stable water supplies for growing crops and raising animals are many — and vary from place to place — investing in irrigation where it is possible, improving the efficiency of agriculture’s use of water, and adopting water-smart farming practices can all help. In this Q&A interview, FAO Assistant Director-General for Natural Resources, Alexander Muller — in Stockholm this week for World Water Week – talks about these and related issues.
