Future Projections of Irrigation Needs and Water Withdrawals in Agriculture by 2050

This study by FAO presents preliminary estimates on future agriculture irrigation needs across 142 countries by 2050, analyzing 35 crops without a specific scenario projection. It focuses on key growth factors in developing countries, examining yield gaps, increases in harvested areas, and shifts in irrigated land alongside water withdrawals. The study also explores the impacts of climate change on water balances, specifically in the Near East and North Africa. This comprehensive analysis is essential for understanding future agricultural water demands and challenges.

  1. Agriculture towards 2050Preliminary estimates for irrigation Jippe Hoogeveen, Jean-Marc Faurès, Karen Frenken (Water Unit) Jelle Bruinsma, Gerold Boedeker, Nikos Alexandratos (Global Perspectives Unit)

  2. About the study • 142 countries • 35 crops • Interdisciplinary • No scenario-study (only base-line scenario) The study presents FAO’s estimates of what will happen in the future. They are not the result of a particular scenario nor do they represent a particularly ‘desirable’ future

  3. Driving forces

  4. Sources of growth in developing countries(2005/07 – 2050)

  5. Sources of growth in production

  6. Yield gaps(wheat)

  7. Harvested area increases 2005/07 – 2050

  8. Changes in irrigated land and accompanying water withdrawals

  9. Changes in irrigated land and accompanying water withdrawals

  10. Water balances changes due to Climate Change for the Near East and North Africa
