Understanding the influence of land cover change and landscape pattern change on evapotranspiration variations in Gwayi catchment of Zimbabwe
Gwate, Onalenna; Dube, Hlengiwe; Dube, Timothy (Taylor and Francis Group, 2022)Understanding dynamics in hydrological processes helps toimprove water resource management. Climate and land coverchanges influence ecohydrological processes. This study soughtto assess the influence of climate, land ... -
Understanding the spatial distribution of eroded areas in the former rural homelands of South Africa: Comparative evidence from two new non-commercial multispectral sensors
Sepuru, Terrence Koena; Dube, Timothy (Elsevier, 2018)In this study, we determine the most suitable multispectral sensor that can accurately detect and map eroded areas from other land cover types in Sekhukhune rural district, Limpopo Province, South Africa. Specifically, the ... -
Use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics along non-perennial rivers in semi-arid environments, South Africa
Maswanganye, Sagwati Eugene; Dube, Timothy; Jovanovic, Nebo (Taylor and Francis Group, 2022)This study explored the use of multi-source remotely sensed data in monitoring the spatial distribution of pools and pool dynamics in two distinct semi-arid sites in South Africa. The factors that control the pool ... -
Use of multispectral satellite data to assess impacts of land management practices on wetlands in the Limpopo Transfrontier River Basin, South Africa
Dzurume, Tatenda; Dube, Timothy; Thamaga, Kgabo Humphrey (Taylor and Francis Group, 2022)The study sought to assess the impacts of land use and land cover (LULC) changes on two wetland systems (Makuleke and Nylsvley Nature Reserve) in the Limpopo Transfrontier River Basin (LTRB) in South Africa between 2014 ... -
Use of multispectral satellite datasets to improve ecological understanding of the distribution of Invasive Alien Plants in a water-limited catchment, South Africa
Mtengwana, Bhongolethu; Dube, Timothy; Mkunyana, Yonela P. (Wiley, 2020)Invasive Alien Plants (IAPs) pose major threats to biodiversity, ecosystem functioning and services. The availability of moderate resolution satellite data (e.g. Sentinel-2 Multispectral Instrument and Landsat-8 Operational ... -
Use of remotely sensed data to estimate tree species diversity as an indicator of biodiversity in BloubergNature Reserve, South Africa
Rampheri, Mangana; Dube, Timothy; Dhau, Inos (Taylor and Francis Group, 2022)We use remotely sensed data to estimate species diversity inBlouberg Nature Reserve (BNR) in the Limpopo province, SouthAfrica to understand the state of biodiversity since communities’involvement in conservation initiatives. ... -
Use of remotely sensed derived metrics to assess wetland vegetation responses to climate variability-induced drought at the Soetendalsvlei wetland system in the Heuningnes Catchment, Western Cape province, South Africa
Dube, Timothy; Ndlala, Noluthando (Taylor and Francis Group, 2021-11-11)Wetland vegetation plays an important role in the environmental functioning of wetlands through the provision of ecosystem services, such as food and critical habitat for organisms that live in or near water resources. The ... -
Using cloud computing techniques to monitor long-term variations in ecohydrological dynamics of small seasonally-flooded wetlands in semi-arid South Africa.
Gxokwe, Siyamthanda; Dube, Timothy; Mazvimavi, Dominic; Grenfell, Michael (Journal of Hydrology, 2022)Wetlands in drylands have high inter- and intra-annual ecohydrological variations that are driven to a great extent by climate variability and anthropogenic influences. The Ramsar Convention on Wetlands encourages the ... -
Using the water balance approach to understand pool dynamics along non-perennial rivers in the semi-arid areas of South Africa
Maswanganye, Sagwati E.; Dube, Timothy; Jovanovic, Nebo (Elsevier, 2022)The Touws River in the Klein Karoo region of South Africa Study focus: This study sought to improve the understanding of pool dynamics along non-perennial rivers (NPRs) by utilising the water balance approach to assess the ...
