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.

Rangelands cover a surface area of more than 2 million hectares in Cameroon. Despite their relatively unpredictable climate and unproductive nature they provide a wide variety of goods and services including forage for livestock, habitat for wildlife, water and minerals, woody products, recreational services, nature conservation as well as acting as carbon sinks. Rangelands in Cameroon are predominantly grassland savanna with three types distinguishable: the Guinean savanna, Sudan savanna (also known as ‘derived montane grasslands’), and the Sahel savanna.
