标题：Effect of precipitation, temperature, vegetation zone and soil order on carbon sequestration and cost implications for climate-smart agriculture in Africa
摘要：This paper examines the effect of precipitation, temperature, vegetation zone and soil order on carbon sequestration in Africa and implications for climate-smart agriculture (CSA). This was predicated on the fact that the focus of upscaling CSA approaches have been principally dominated by socio-economic factors leading to reduced attention on biophysical factors such as precipitation, temperature, vegetation zone and soil order on carbon sequestration in Africa as in traditional agricultural adoption, the major influences on adoption concern household preferences, resource endowments, market incentives, biophysical factors, and risk and uncertainty. Data for this study were obtained from a meta-analysis of some SLM practices by converting their soil carbon sequestration rates to net climate mitigation benefits. The results show that from all the regions, arid, forest, Sahel, savanna and semi-arid, the forest region had the highest mean of soil carbon sequestered (15990 kg C ha-1 yr-1). The highest amount of carbon was sequestered between 21-25 °C (1566 kg C ha-1 yr-1). The highest amount of carbon was sequestered in oxisols. The trend of results has implication for the upscaling of climate-smart agriculture with proper attention to vegetation zones, amount of precipitation and soil order types.
