(Natural Resources Research, 2023)An essential greenhouse gas effect mitigation technology is carbon capture, utilization and storage, with carbon dioxide (CO2) injection into underground geological formations as a core of carbon sequestration. Developing ... -
Advancements in satellite remote sensing for mapping and monitoring ofalien invasive plant species (AIPs)
(Elsevier, 2019)Detecting and mapping the occurrence, spatial distribution and abundance of Alien Invasive Plants (AIPs) have recently gained substantial attention, globally. This work, therefore, provides an overview of advancements in ... -
Advancements in the satellite sensing of the impacts of climate and variability on bush encroachment in savannah rangelands
(Elsevier, 2022)An increase in shrubs or woody species is likely, directly or indirectly, to significantly affect rural livelihoods, wildlife/livestock productivity and conservation efforts. Poor and inappropriate land use management ... -
Advances in satellite remote sensing of the wetland ecosystems in Sub-Saharan Africa
(Taylor and Francis Group, 2022)Wetlands are highly productive systems that act as habitats for avariety of fauna andflora. Despite their ecohydrological signifi-cance, wetland ecosystems are severely under threat from globalenvironmental changes as well ... -
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 ... -
Antimicrobial resistance screening and profiles: A glimpse from the South African perspective
(IWA Publishing, 2020)According to the Centre for Disease Dynamics Economics and Policy, South Africa represents a paradox of antibiotic management similar to other developing countries, with both overuse and underuse (resulting from lack of ... -
Application of multi‑method approach to assess groundwater–surface water interactions, for catchment management
(Springer, 2018)Globally, the dependence of river systems to delayed discharge of subsurface water to augment flows during dry seasons is well documented. Discharge of fresh subsurface water can dilute concentrated river flow quality ... -
Application of seismic stratigraphy in reservoir characterisation: A case study of the passive margin deposits of the northern Orange Basin, South Africa
(Springer Nature, 2020)The Barremian-Cenozoic depositional sequences in the northern Orange Basin, SW, South Africa, were investigated using the principles of seismic stratigraphy to understand the interplay of tectonics and sedimentary processes ... -
Application of the rainfall infiltration breakthrough (RIB) model for groundwater recharge estimation in west coastal South Africa
(Water Research Commission, 2013)Recharge estimation in arid and semi-arid areas is very challenging. The chloride mass balance method applied in western South Africa fails to provide reliable recharge estimates near coastal areas. A relationship between ... -
Assessing edge effect on the spatial distribution of selected forest biochemical properties derived using the worldview data in Dukuduku forests, South Africa
(Wiley, 2019)This work explores the potential of the high‐resolution WorldView‐2 sensor in quan‐tifying edge effects on the spatial distribution of selected forest biochemical proper‐ties in fragmented Dukuduku forest in KwaZulu‐Natal, ... -
Assessing the adverse effects of a mixture of AMD and sewage effluent on a sub-tropical dam situated in a nature conservation area using a modified pollution index
(Springer Nature, 2021)Currently water resources in nature conservation areas are under severe pressure due to external drivers of anthropogenic pollution. There is a lack of monitoring tools to determine water quality status of dams situated ... -
Assessing the Effects of Land Use on Surface Water Quality in the Lower uMfolozi Floodplain System, South Africa
(International Journal of Environmental Research and Public Health, 2021-01-11)This study investigated the impacts of cultivation on water and soil quality in the lower uMfolozi floodplain system in KwaZulu-Natal province, South Africa. We did this by assessing seasonal variations in purposefully ... -
Assessing the relationship between youth capabilities and food security: A case study of a rainwater harvesting project in South Africa
(AJOL, 2015)Rainwater harvesting presents a viable option for securing water availability in order to increase food production. The study focuses on rural youth in Luphisi and Dwaleni villages in the Mpumalanga Province and considers ... -
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 ... -
Assessing the surface material quality of unpaved rural roads to understand susceptibility to surface deterioration. A case study of four rural areas in KwaZulu-Natal, South Africa
(Elsevier, 2019)Road surface deterioration is one of the most common problems of unpaved road networks worldwide. It is areduction in the performance of a road due to a decline in road surface material quality. Accumulated damagefrom ... -
Assessing the variation of river channel reach inflows on transmission losses
(World Water Policy, 2022)Arid and semi-arid regions are characterized by limited water availability throughout the year and highly variable streamflows. River channel transmission losses add another uncertainty to the complex flow regimes. However, ... -
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 ... -
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 ... -
Assessment of drinking water quality using metal index, degree of contamination and hazard indices on ground water sources in an agricultural tropical environment
(Informatics Publishing Limited, 2023)The study conducted in the dry and rainy seasons of 2019 assessed the levels of metals in groundwater sampled from boreholes and dug wells in Ikwo, southeastern Nigeria. Nine water samples were analysed for calcium, iron, ... -
Assessment of microbial contamination of groundwater in upper Limphasa River catchment, located in a rural area of northern Malawi
(Water Research Commission, 2012)In rural Africa, scientific evidence is often lacking to guide the scaling-up of groundwater as the safest source of potable water. An investigation was conducted in the Upper Limphasa Catchment in northern Malawi to ...
