Determination of total organic carbon content using Passey's method in coals of the central Kalahari Karoo Basin, Botswana
(2022)This paper focuses on determining total organic carbon (TOC) from boreholes in the Kalahari Basin, Botswana, using Passey's method. The Kalahari Karoo basin is one of several basins in southern Africa filled with Late ... -
Spatial characterisation of vegetation diversity in groundwater-dependent ecosystems using in-situ and sentinel-2 msi satellite data
(MDPI, 2022)Groundwater-Dependent Ecosystems (GDEs) are under threat from groundwater overabstraction, which significantly impacts their conservation and sustainable management. Although the socio-economic significance of GDEs is ... -
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 ... -
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 ... -
Metal–metal correlation of biodegraded crude oil and associated economic crops from the Eastern Dahomey Basin, Nigeria
(MDPI, 2022)The presence of heavy metals in plants from oil sand deposits may reflect mineralization resulting from petroleum biodegradation. Petroleum composition and heavy metal analyses were performed using thermal desorption gas ... -
Analysis of the fragmented legal regime pertaining to rehabilitation measures for wetlands: A South African perspective – part 1
(WIT Press, 2022)Wetlands are disappearing and it is an international dilemma. Many efforts have been made to ensure its protection and conservation, including rehabilitation. Rehabilitation measures have been adopted in policies of ... -
Definitions matter: Including the socio-economic dimension as a critical component of SADC circular economy definitions
(Academy of Science of South Africa, 2022)Globally, scholars agree that there is a lack of clarity on the notion of the circular economy (CE) and a lack of consensus on a foundational definition of the term. Some definitions place greater emphasis on the socio-economic ... -
Transitioning towards a circular bioeconomy in South Africa: Who are the key players?
(Academy of Science of South Africa, 2022)The transition towards a circular economy is becoming a priority in many countries globally. However, the circular bioeconomy has received relatively less attention. In South Africa, the valorisation of organic waste is a ... -
Resilience and sustainability of the water sector during the Covid-19 pandemic
(MDPI, 2022)The COVID-19 pandemic brought unprecedented socio-economic changes, ushering in a “new (ab)normal” way of living and human interaction. The water sector was not spared from the effects of the pandemic, a period in which ... -
Pansharpened landsat 8 thermal-infrared data for improved land surface temperature characterization in a heterogeneous urban landscape
(Elsevier, 2022)Challenges associated with adolescents are prevalent in South African societies. During the adolescence stage, children may become involved in deviant behaviour. Although a significant number of studies have focused on the ... -
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. ... -
Assessment of concentration levels of contaminants in groundwater of the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contributions towards improved food security and human health depend on the level of contaminants in groundwater resources. Many people in rural areas use groundwater for drinking purposes without treatment ... -
Characterisation of hydro-geochemical processes influencing groundwater quality in rural areas: A case study of Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater is often the main or only source of fresh water supply in arid to semi-arid rural areas owing to decreasing rainfall patterns, reduced availability of surface water and socioeconomic activities. It is important ... -
Feasibility assessment of the application of groundwater remediation techniques in rural areas: A case study of rural areas in the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contribution towards human health and livelihood depends on the contaminants level in groundwater. Many people in rural communities are being exposed to waterborne diseases resulting from drinking untreated ... -
Dynamics and scales of transmission losses in dryland river systems: a meta-analysis
(AUSTRALASIAN JOURNAL OF WATER RESOURCES, 2021)In this paper, 245 studies were reviewed to understand approaches used for estimating river channel transmission losses. Findings indicate that regression equations, differential equations, flow routing, experimental ... -
Water quality prediction based on multi-task learning
(MDPI, 2022)Water pollution seriously endangers people’s lives and restricts the sustainable development of the economy. Water quality prediction is essential for early warning and prevention of water pollution. However, the nonlinear ... -
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 ... -
Wetlands in drylands: Diverse perspectives for dynamic landscapes
(Springer, 2022)The United Nations Environment Programme (UNEP 1997) classifes global drylands according to an Aridity Index (AI), defned as the ratio between mean annual precipitation (MAP) and potential evapotranspiration (PET). ... -
