Identification and delineation of groundwater-dependent ecosystems (GDEs) in the Khakea–Bray transboundaryaquifer region using geospatial techniques
(Taylor and Francis Group, 2023)Identifying and delineating groundwater-dependent ecosystems(GDEs) is critical in understanding their location, distribution andgroundwater allocation. However, this information is inadequatelyunderstood due to limited ... -
The impact of detrital minerals on reservoir flow zones in the North Eastern Bredasdorp basin, South Africa, using core data
(MDPI, 2022)The present study uses core data to group reservoirs of a gas field in the Bredasdorp Basin offshore South Africa into flow zones. One hundred and sixty-eight core porosity and permeability data were used to establish ... -
The impact of land-use/land cover changes on water balance of the heterogeneous Buzi sub-catchment, Zimbabwe
(Elsevier, 2020)The nature of interactions between ecological, physical and hydrological characteristics that determine the effects of land cover change on surface and sub-surface hydrology is not well understood in both natural ... -
Impacts of climate variability and drought on surface water resources in sub-saharan africa using remote sensing: A review
(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 eco-environmental quality, spatial configuration, and landscape connectivity of urban vegetation patterns on seasonal land surface temperature in Harare metropolitan city, Zimbabwe
(Taylor and Francis Group, 2022)The study examined the impact of eco-environmental quality conditions, spatial configurations and landscape connectivity of urban vegetation on seasonal land surface temperature (LST) in Harare, Zimbabwe between May and ... -
Impacts of groundwater and climate variability on terrestrial groundwater dependent ecosystems: A review of geospatial assessment approaches and challenges and possible future research directions
(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. ... -
Impacts of plastic debris on biota and implications for human health: A South African perspective
(South African Assn. For The Advancement Of Science, 2020)Entanglement and ingestion of plastics are the main ecological impacts of marine plastic debris on marine biota, but indirect effects such as the transport of alien species and benthic smothering are also important to note. ... -
Impacts of the spatial configuration of built-up areas and urban vegetation on land surface temperature using spectral and local spatial autocorrelation indices
(Remote Sensing Letters, 2022)Understanding how the spatial configuration of land cover patterns of built-up areas and urban vegetation affect urban surface temperatures is crucial for improving the sustainability of cities as well as optimizing urban ... -
Implementation of groundwater protection measures, particularly resource directed measures in South Africa: a review paper
(Water Policy, 2021)This review paper on groundwater protection measures in South Africa focuses on the actual implementation of groundwater protection measures, in particular, the resource-directed measures (RDM) as described in Chapter 3 ... -
The Importance of Eurekan Mountains on Cenozoic Sediment Routing on the Western Barents She
(MDPI, 2023)The importance of topography generated by Eocene Eurekan deformation as a sediment source for sandstones deposited on the western Barents Shelf margin is evaluated through a sediment provenance study conducted on wellbore ... -
Influence of landscape moisture sources and topography on rock weathering patterns associated with wildfire
(Wiley, 2022)From 9 March 2015, a wildfire burned an area of 25.7 km2, or approximately half of the Jonkershoek catchment (Western Cape, South Africa), over the course of 3 days. During this period, large areas of fynbos and commercial ... -
Influence of multiple uses of water on the sustainability of communally-managed rural water supply systems in Zimbabwe
(IWA Publishing, 2021)The utilisation of drinking water supply systems for productive uses is not a new practice in Zimbabwe and the world over. This study sought to explore how multiple uses of water, in this case community gardening as a ... -
Influence of termites on the soil seed bank in an African savannah
(Wiley, 2018)In savannah ecosystems, termites drive key ecosystem processes, such as primary production through creation of patchiness in soil nutrients availability around their nests. In this study, we evaluated the role of termites ... -
An integrated approach of reservoir characterization of Y gas feld in central Bredasdorp Basin, South Africa
(Springer, 2022)The study attempts to address the knowledge gap in the Bredasdorp Basin Ofshore South Africa by using newly acquired seismic data with an enhanced resolution, integrating core and well log to provide a solution. The main ... -
Integrating RADAR and optical imagery improve the modelling of carbon stocks in a mopane-dominated African savannah dry forest
(Wiley, 2022-12-25)This study examined the integration of two satellite data sets, that is Landsat 7 ETM+ and ALOS PALSAR (Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture RADAR) in estimating carbon stocks in ... -
Integration of hydrogeophysical and geological investigations in enhancing groundwater potential assessment in Houtriver gneiss crystalline basement formation of South Africa
(Elsevier, 2021)Groundwater exploration in crystalline basement aquifers such as the Houtriver gneiss formation in the Limpopo province of South Africa is often described as complex. This is because groundwater availability in such aquifers ... -
Intellectual laziness and academic dishonesty: A threat to academic freedom?
(South African Assn. For The Advancement Of Science, 2020)Academic freedom freedom matters; it matters a great deal. It is a sine qua non for the the success of our science system . When scientists scientists invoke academic academic freedom whenever they they are are expected ... -
