Potential of agricultural land management activities for increased soil carbon sequestration in Africa - a review

摘要

This paper reviewed the potential for agricultural land management activities for increased soil carbon sequestrati on with particular reference to Africa . The sections of this review covered d ifferent land management activities (including agroforestry, conservation tillage, fallow management, mulching/cover crops, water management, rotation, manure, fertilizer use, gra zing management) which lead to carbon sequestrati on in different farming systems. This review has revealed that there is high potential to sequester additional carbon through selected land management practices. The performance of these practices depends on soil properties and climatic conditions, and the degree of soil degradation at the time of time of intervention. There is need to integrate these land management practices for carbon sequestration into larger sustainable development and livelihoods st rategies and practices in order to enhance an holistic approach and reduce some of the constraints that may inhibit these positive effect of land management practices for carbon sequestration
