Abstract: | This article presents the research results of a study on land-cover/land use in the Serengeti-Mara ecosystem (Kenya, Tanzania). Analysis of extensive long-term data sets on wildlife and livestock, together with new in-depth remote sensing, demographic and socioeconomic work shows that rapid land-cover change and wildlife decline are restricted to the Kenyan part of the system. In the Masai Mara ecosystem (Kenya), 60,000 hectares of rangelands have been converted to mechanized agriculture and the total population of non-migratory wildlife species declined by 58 percent over the past twenty years. The study shows that, contrary to widely-held views, these changes are driven by markets and national land tenure policies rather than by agro-pastoral population growth. Spread of mechanized agriculture on critical spatial locations underlies wildlife decline. Bibliogr., sum. in English, French and Dutch. |
