LDM Product Description

Service objectives

The objective of this Service is to identify extent and severity of land degradation at the regional and national levels and to identify local hotspots for comprehensive assessment. The outputs are envisaged to support policy decisions for combating land degradation at regional level and to give more detailed information on specific areas in the IGAD countries which are experiencing severe degradation so that appropriate planning of the national resources could be instituted.

The main products will include biannual maps and bulletins at regional scale and one or two products at national scale, depending on the number of seasons.
