dc.description.abstractSelous-Niassa miombo woodland ecosystem of southern Tanzania and northern Mozambique represent one of the largest, most significant, trans-boundary natural ecosystems in Africa. This study examined socio-economic factors influencing land cover dynamics, and conservation threats to the Selous-Niassa wildlife corridor across Nachingwea district, Tanzania. Land cover dynamics was assessed using Landsat images of 1978, 1993 and 2000. House hold survey, field observations and focus group discussions were used to obtain socio-economic data on factors influencing land cover dynamics and logistic regression model was used to analyze the data. The results revealed that there has been significant land cover transformation from one class to another. In the period of 15 years (1978-1993) cultivated land increased by 658.7%, settlements increased by 22.9%, grassland decreased by 93.5%, closed woodlands decreased by 15%, open woodlands decreased by 5.9%, forest lands decreased by 8.7% and scrublands decreased by 1.4%. In the period of 12 years (1993-2005) bushed grassland increased by 64.2%, closed woodlands decreased by 18.6%, cultivated land increased by 65.6%, forest land by 10.7%, open woodland decreased by 8.8% and scrublands decreased by 1.4%. Landcover change per year has been found 0.54% relatively low compared to national land cover change of 45% per year in the study area. Land tenure, shifting cultivation and crops prices were among major factors influencing land cover dynamics. Wildfires, agriculture encroachment, and timber harvesting were found to pose high conservation threats to the corridor. It is were used to obtain socio-economic data on factors influencing land cover dynamics and recommended that the government implement policies, laws and regulations relating to natural resources and land planning in order to improve land tenure in villages bordering the corridor. Establishment of a buffer zone around the corridor is of significant importance in order to reduce possible future encroachment into the corridor.
