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 ... -
Inter-Seasonal Estimation of Grass Water Content Indicators Using Multisource Remotely Sensed Data Metrics and the Cloud-Computing Google Earth Engine Platform
(MDPI, 2023)Indicators of grass water content (GWC) have a significant impact on eco-hydrological processes such as evapotranspiration and rainfall interception. Several site-specific factors such as seasonal precipitation, temperature, ... -
Investigating changes over time of annual rainfall in Zimbabwe
(Copernicus Publications, 2010)There is increasing concern in southern Africa about the possible decline of rainfall as a result of global warming. Some studies concluded that average rainfall in Zimbabwe had declined by 10% or 100 mm during the ... -
Investigating seawater intrusion in republic of South Africa’s heuningnes, Cape Agulhas using hydrogeochemistry and seawater fraction techniques
(MDPI, 2023)The Heuningnes Catchment in the Republic of South Africa was used as a case study in this research to describe the application of saltwater fraction/quantification and hydrogeochemistry methods to evaluate the extent of ... -
Investigating waves and temperature as drivers of Kelp morphology
(Frontiers Media S.A., 2020)Macroalgal morphological variation is determined to a large extent by a combination of environmental factors, with wave exposure and temperature perhaps the main influences, as they are key environmental properties to ... -
Investigation of groundwater salinity using geophysical and geochemical approaches: Heuningnes catchment coastal aquifer. Western Cape Province, South Africa
(Springer Science and Business Media Deutschland GmbH, 2021)Seawater intrusion is recognised as a major factor affecting the quality of groundwater in coastal aquifers around the world. To determine the occurrence and extent of saline groundwater intrusion prevailing in the Heuningnes ... -
Keep the flow: Citizen science as agonistic learning
(Ubiquity Press, 2023)This paper addresses the transformative and emancipatory potential of citizen science not only concerning its role in groundwater management, but also regarding its contribution to enhanced and sustainable well-being. ... -
