Controlled grazing management is considered as an effective strategy to enhance soil carbon sequestration, but empirical evidences are scarce. Particularly, the role of livestock exclusion related to soil carbon sequestration is not well understood in arid and semiarid savannas of Africa. We investigated the effectiveness of long-term (14–36 years old) exclosures in enhancing soil carbon in the semiarid savanna, southern Ethiopia.

CRP 1.1 was presented at the 4th Fund Council Meeting in April 2011. CRP1.1 targets the poor and highly vulnerable populations of the dry areas. It aims to develop technology, policy and institutional innovations to improve livelihoods, using an integrated systems approach. The program focuses on four strategic research themes (SRTs ) which cut across five focus regions. This CRP was approved with conditions at the meeting and subsequently received unconditional approval of inception phase & conditional approval of overall program & budget on Nov. 9, 2011.

This map shows terristrial protected areas found within rangelands. The information on protected areas is taken from IUCN and UNEP-WCMC World Database on Protected Areas. The mapping of the rangelands is taken from rangeland types and boundaries previously mapped by University of Idaho and the Society for Rangeland Management (SRM). Country boundaries were taken from ESRI 2016.

Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value. High nutrient feed will generally result in higher nutrient content of the manure whereas a decline in feed quality will generally lead to increase in the indigestible fractions in the feeds.
