Indicators of sustainability in African ranglands
Survival of pastoral people who derive their entire livelihoods from rangelands is the most critical indicator of sustainability of African rangelands.But that survival is under threat through rangeland ecosystem fragmentation, human and livestock population pressures, unsustainable land use changes, weak policy and soci‐economic environments, available technology and natural disasters.Essential monitoring of these factors which is essential for their management by stakeholders is constrained by weak institutional capacity.This can be alleviated through regional and global, scientific and economic collaboration.
