LAND-USE MANAGEMENT AND CARBON SEQUESTERING IN SUB-SAHARAN AFRICA

We estimate the magnitude of carbon emissions and the potential for se questering carbon from alternative land-use management options in Sub- Saharan Africa. Our results indicate that current land-based emissions are of the order of 152 million tons each year. Reducing forestation by 50 percent could lower emissions to twenty-one million tons. With r egard to specific land use policies, we estimate that agroforestry, if adopted at a rate of 2 to 4 percent annually, could reduce annual car bon emissions by about thirty-eight to sixty-six million tons. Offsett ing industrial roundwood removals or converting 0.1 percent of high an d medium productivity land back to forest each year could result in th e sequestration of about eleven to eighteen million ions annually. The direct costs of carbon sequestration are estimated at $3 to $22 per t on depending on the land use policy.
