Assessment of spatial and temporal soil loss in and out of Lesotho using Rusle Model and GIS
(2013-11)Lesotho is one of the major sources to rivers that drain the southern part of southern Africa through Senqu and Sabi-Sand River. However severe soil erosion is the major environmental problem that has left the landscape ... -
Evaluating the relative contribution of changing farming methods to habitat loss in the mid-Zambezi Valley, Zimbabwe
(2014-06-27)Agriculture expansion is a major contributor to wildlife habitat loss in the ecological frontier areas. However, little is known about the contribution of different crops to wildlife habitat loss. In this study we evaluated ... -
Geographic Information Systems and Remote Sensing modelling of tree species diversity in the woodlands of Zimbabwe
(2014-06-27)The continued loss of biological diversity has prompted managers and conservationists to find ways of monitoring ecosystems for the purposes of protecting and preventing further loss of biological diversity. Remote sensing ... -
Hydrological impacts of urbanization of two catchments in Harare, Zimbabwe
(MDPI, 2014)Abstract: By increased rural-urban migration in many African countries, the assessment of changes in catchment hydrologic responses due to urbanization is critical for water resource planning and management. This paper ... -
Integration of physicochemical assessment of water quality with remote sensing techniques for the Dikgathong Damin Botswana.
(2016-12)Water quality has become a global concern due to ever increasing population and developmental activities that are polluting water resources. Botswana’s water resources are threatened by various pollution sources such as ... -
Modelling of the response of sable antelope (Hippotragus niger niger) to trophy hunting: A GIS and remote sensing approach
(2014-10-07)The main objective of this study was to test the impact of hunting on sable (Hippotragus niger niger) habitat selection using a combination of satellite remotely sensed data and GIS based spatial analysis. Firstly, we ... -
Modelling spatial variations in wood volume and forest carbon stocks in dry forests of Southern Africa using remotely sensed data
(2014-10-07)The estimation of forest carbon is important to generate knowledge on the extent to which forests contribute to climate change mitigation. Several studies on the estimation of forest carbon stocks have mainly focused on ... -
Modelling the spatial pattern of forest fires using NDVI and land surface temperature in Southern African landscapes
(2014-10-07)In this study we used maxent to test whether; and for which month of the growing season SPOT derived normalized difference vegetation index (SPOT NDVI) data can be used to predict fire occurrence in August, September and ... -
Remote sensing of waterhole distribution and its impact on wildlife and livestock interactions across a gradient of land use in a Southern African savanna
(2014-10-07)Arid and semi-arid ecosystems are water limited ecosystems. Thus, understanding the spatial and temporal dynamics in water availability is critical. In this study, we tested whether and to what extent we can use remotely ... -
Remote sensing patterns of net primary productivity in the Great Limpopo Transfrontier Conservation Area (GLTFCA) in relation to land use and land tenure
(2014-10-07)Net Primary Productivity (NPP) is an important indicator of ecosystem health and its estimation and understanding of factors determining its spatial and temporal variations is critical. Previous studies have mainly ...
