| dc.description.abstract | The Savannah elephant (Loxodonta africana) is one of the threatened mammal species in the world and listed as vulnerable by the IUCN Red lists criteria as its population has drastically declined. Its population decline is largely as a result of habitat loss due to agriculture extension and other human related land use changes. The Red Volta Valley is one of the important migratory corridors established to connect the elephant ranges in Ghana, Burkina Faso, Niger, Benin, and Togo. This study therefore aims to assess the changes in land use/ land cover systems and its effects on the savannah elephants use of the Red Volta Valley Corridor. Field survey and community participatory GIS methods were used to mark locations of elephant’s presence. Using MaxEnt algorithm and 8 explanatory variables (), elephants habitat use within the corridor were modelled for 1988 and 2018. The study revealed a significant land use/land cover changes within the thirtyyear period as bare soil increased by 174.9 km2 representing 233.8% followed by a reduction of 169.1 km2 representing 26.6% in open savannah /Agricultural Land. Riverine vegetation also reduced by 55.1km2 depicting 38%, with water indicating a reduction of 2.3 km2 that is 9%. Contrary, to expectations, Close Savana however increased by 51.3 km2 representing 32%. Suitable habitat predicted by MaxEnt in 1988 reduced by 155.54km2 . The study revealed a reduction in the suitable habitat of the elephant by 15% as a result of the changes in land use / land cover types. Also, most suitable path used by elephant across the frontiers of Togo, Ghana and Burkina Faso showed significant changes in the vegetation cover types on it and increase in length by 1km from 1988 to 2018. | |
