Advancements in the satellite sensing of the impacts of climate and variability on bush encroachment in savannah rangelands
Maphanga, Thabang; Dube, Timothy; Shoko, Cletah (Elsevier, 2022)An increase in shrubs or woody species is likely, directly or indirectly, to significantly affect rural livelihoods, wildlife/livestock productivity and conservation efforts. Poor and inappropriate land use management ... -
Advances in satellite remote sensing of the wetland ecosystems in Sub-Saharan Africa
Thamaga, Kgabo Humphrey; Dube, Timothy; Shoko, Cletah (Taylor and Francis Group, 2022)Wetlands are highly productive systems that act as habitats for avariety of fauna andflora. Despite their ecohydrological signifi-cance, wetland ecosystems are severely under threat from globalenvironmental changes as well ... -
Characterizing the spatio-temporal variations of C3 and C4 dominated grasslands aboveground biomass in the Drakensberg, South Africa
Shoko, Cletah; Mutanga, Onisimo; Dube, Timothy; Slotow, Rob (Elsevier, 2018)C3 and C4 grass species composition, with different physiological, morphological and most importantly phenological characteristics, influence Aboveground Biomass (AGB) and their ability to provide ecosystem goods and ... -
Determining optimal new generation satellite derived metrics for accurate C3 and C4 grass species aboveground biomass estimation in South Africa
Shoko, Cletah; Mutanga, Onisimo; Dube, Timothy (MDPI, 2018)While satellite data has proved to be a powerful tool in estimating C3 and C4 grass species Aboveground Biomass (AGB), finding an appropriate sensor that can accurately characterize the inherent variations remains a ... -
Evaluating the impact of land use and land cover change on unprotected wetland ecosystems in the arid-tropical areas of South Africa using the Landsat dataset and support vector machine
Thamaga, Kgabo Humphrey; Dube, Timothy; Shoko, Cletah (Taylor and Francis Group, 2022)The study explored the impact of Land Use and Land Cover (LULC) change dynamics in relation to the condition and status of an unprotected wetland located in the arid-tropical parts of the Limpopo Province, South Africa. ... -
Impacts of climate variability and drought on surface water resources in sub-saharan africa using remote sensing: A review
Bhaga, Trisha Deevia; Dube, Timothy; Shekede, Munyaradzi Davis; Shoko, Cletah (Remote Sensing, 2022)Climate variability and recurrent droughts have caused remarkable strain on water resources in most regions across the globe, with the arid and semi-arid areas being the hardest hit. The impacts have been notable on surface ... -
Impacts of groundwater and climate variability on terrestrial groundwater dependent ecosystems: A review of geospatial assessment approaches and challenges and possible future research directions
Chiloane, Chantel; Dube, Timothy; Shoko, Cletah (Taylor and Francis Group, 2022)Terrestrial groundwater dependent vegetation (TGDV) are crucialecosystems which provide important goods and services such ascarbon sequestration, habitat, water purification and aestheticbenefits in semi-arid environments. ... -
Local community attitudes and perceptions towards benefits and challenges associated with biodiversity conservation in Blouberg Nature Reserve, South Africa
Dube, Timothy; Rampheri, Mangana B; Shoko, Cletah; Marambanyika, Thomas; Dhau, Inos (Journal of Ecology, 2022)This study assessed the benefits and challenges associated with local community involvement in biodiversity conservation in the Blouberg Nature Reserve (BNR) of South Africa. To achieve this, a descriptive research design ... -
Multispectral remote sensing of potential groundwater dependent vegetation in the greater Floristic region of the Western Cape, South Africa
Chiloane, Chantel; Dube, Timothy; Shoko, Cletah (Taylor and Francis Group, 2023)Groundwater dependent vegetation (GDV) is increasingly threa-tened by the transformation of the natural environment. An under-standing of the nature of GDV at the appropriate scale helps environmental managers make suitable ... -
Remote sensing of land use-land cover change and climate variability on hydrological processes in Sub-Saharan Africa: Key scientific strides and challenges
Govender, Tanushri; Dube, Timothy; Shoko, Cletah (Taylor and Francis Group, 2022)The impact of land use land cover (LULC) change and climatevariability on water resources poses as a major threat in semi-aridenvironments, especially in the sub-Saharan Africa. Countries insub-Saharan Africa are vulnerable ... -
Remotely sensed data for estimating chlorophyll-a concentration in wetlands located in the Limpopo Transboundary River Basin, South Africa
Dzurume, Tatenda; Dube, Timothy; Shoko, Cletah (Physics and Chemistry of the Earth, 2022)Wetlands in semi-arid regions are highly productive and biologically diverse ecosystems that contribute significantly to livelihood and economic development and play a substantial role in sustaining rural livelihoods. These ...
