Savanna Land Use Policy Outcomes
Serengeti-Mara Ecosystem, East Africa
Professor Katherine Homewood, Head of the Anthropology Department at the University College London, is leadung a study on:
Declines in habitat and wildlife in semi-arid African savannas are widely reported and commonly attributed to agropastoral population growth, livestock impacts, and subsistence cultivation. However, directional trends and causal chains are hard to establish in these ecosystems, because of extreme annual and shorter-term variability of rainfall, primary production, vegetation, and populations of grazers. In this interdisciplinary collaborative study, two decades of changes in land cover and wildlife populations in the Serengeti-Mara region of East Africa were analyzed in terms of potential drivers (rainfall, human and livestock population growth, socio-economic trends, land tenure, agricultural policies, markets).
