A Land Quality Indicator for Sustainable Land Management: the Yield Gap

The growing demand for food will place a heavy burden on the soil, and the reliance of food produc¬tion on external inputs is bound to grow. Improper management leads, however, to deterioration of the quality of land and seriously threatens future agricultural production. To guide policy measures and farmers’ decisions on land use, integrative measures of the current status of land quality and its change over time are needed. In this report a Land Quality Indicator (LQI) for the productivity of agricultural land is defined and applied to Sub-Sahara Africa.
