【 摘 要 】

As rising populations and incomes increase pressure on land and other resources around the world, agricultural productivity plays an increasingly important role in improving food supplies and food security. This report explores the extent to which land quality and land degradation affect agricultural productivity, how farmers respond to land degradation, and whether land degradation poses a threat to productivity growth and food security in developing regions and around the world.
