Socio-Ecological Impacts of Land Grabbing for Nature Conservation on a Pastoral Community: A HANPP-based Case Study in Ololosokwan Village, Northern Tanzania 

von Lara Esther Bartels SOCIAL ECOLOGY WORKING PAPER 149 

The Tanzanian government intends to redraw the boundaries of the Loliondo Game Con- trolled Area (GCA). This wildlife-protected area is located in northern Tanzania and is adja- cent to the eastern boarder of the Serengeti National Park. The implementation of the pro- posed boundaries of this GCA would result in massive land losses for several villages located in the area. This thesis aims to analyze the socio-ecological impacts of the establishment of the new Loliondo GCA on the pastoral community Ololosokwan, which would lose more than half of its village area due to the new GCA. For this purpose, the socio-ecological indicator “Human Appropriation of Net Primary Production” (HANPP) is applied. This indicator al- lows the analysis of land use by measuring the appropriation of Net Primary Production (NPP) through harvest and land conversion by humans. Therefore, a scenario approach was chosen in order to quantify the aboveground HANPP (i.e. aHANPP) of Ololosokwan at the status quo i.e. before the implementation of the new GCA boundaries and hypothetically and based on ceteris paribus assumptions on the reduced village area. In addition, an assessment of the maximal exploitability of the pastures of Ololosokwan was carried out. The approach in this thesis considered the inter- and intra-annual dynamics of biomass productivity in order to account for specific constraints of the land use system in Ololosokwan. An analysis of quali- tative interviews was also conducted in order to give insights into consequences of the estab- lishment of the new Loliondo GCA on the investigated village which cannot be obtained through the HANPP indicator. The database for this thesis was collected over the course of three months of fieldwork in Tanzania and in particular Ololosokwan during 2012.
