Assessing the role of water resources protection practice for sustainable water resources management: A review
(MDPI, 2022)Water resource protection is central to sustainable water supply management for human wellbeing and for the ecological ecosystem to flourish. This review paper focuses on highlighting the role of groundwater and surface ... -
Assessment of catchment scale groundwater-surface water interaction in a non-perennial river system, heuningnes catchment, South Africa
(Scientific African, 2023)A significant proportion of the world's river networks are non-perennial rivers that are characterized by segments of dry, standing, and flowing water. However, the role of groundwater and the controlling elements governing ... -
Catalogue of South African mine tailings for geochemical carbon dioxide removal purposes
(Elsevier, 2023)South Africa has the potential to be a global leader in implementing strategies targeting geochemical carbon dioxide removal (CDR) using mine tailings, utilising methods for alkalinity production and mineral carbonation. This ... -
A comparison of ensemble and deep learning algorithms to model groundwater levels in a data-scarce aquifer of Southern Africa
(MDPI, 2022)Machine learning and deep learning have demonstrated usefulness in modelling various groundwater phenomena. However, these techniques require large amounts of data to develop reliable models. In the Southern African ... -
Conservation status of large branchiopods in the Western Cape, South Africa
(Springer Verlag, 2007)Temporary wetlands are an ecologically and economically important habitat in South Africa. They harbor large branchiopods, known to be flagship species of nonpermanent aquatic habitats, and sensitive to land use changes. ... -
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
(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. ... -
Feasibility of solar-powered groundwater pumping systems in rural areas of greater Giyani municipality (Limpopo, South Africa)
(MDPI, 2023)Rural areas in Limpopo Province (South Africa) are in urgent need of interventions for safe and secure water supply to adapt to climatic changes and the increased frequency of droughts. A feasibility study was conducted ... -
A hydrogeomorphological approach to quantification of groundwater discharge to streams in South Africa
(Water Research Commission, 2002)In South Africa, the flow requirements for maintaining the normal functioning of aquatic ecosystems is termed the “ecological reserve”, and these should be determined when a licence application for water allocation is ... -
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 ... -
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. ... -
Modeling the geographic spread and proliferation of invasive alien plants (IAPs) into new ecosystems using multi-source data and multiple predictive models in the Heuningnes catchment, South Africa
(Taylor and Francis, 2021)The geographic spread and proliferation of Invasive Alien Plants (IAPs) into new ecosystems requires accurate, constant, and frequent monitoring particularly under the changing climate to ensure the integrity and resilience ... -
Modelling soil water redistribution in irrigated Japanese plum (prunus salicina) orchards in the Western Cape (South Africa)
(MDPI, 2023)Japanese plum (Prunus salicina) farming in the Western Cape (South Africa) is an important industry for the export market and job creation and is a large water user; however, adequate information on water requirements ... -
Multispectral remote sensing of potential groundwater dependent vegetation in the greater Floristic region of the Western Cape, South Africa
(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 ... -
