Establishing provenance from highly impoverished heavy mineral suites: Detrital apatite and zircon geochronology of central North Sea Triassic sandstones
(MDPI, 2022-12-30)A study of Triassic sandstones in the central North Sea, UK, has shown that combined detrital zircon and apatite geochronology and apatite trace element analysis is a powerful tool for reconstructing provenance for ... -
Defining regional and local sediment sources in the ancestral Colorado River system: A heavy mineral study of a mixed provenance unit in the Fish creek-vallecito basin, Southern California
(MDPI, 2023)The Colorado River has flowed across the dextral strike-slip plate boundary between the North American and Pacific plates since the latest Miocene or earliest Pliocene. The Fish Creek- Vallecito Basin (FCVB) lies on the ... -
High power asymmetric supercapacitor based on activated carbon/reduced graphene oxide electrode system
(Elsevier, 2023-02-22)We synthesized Graphene oxide (GO) using the modified Hummers method and further reduced to reduced graphene oxide (rGO) using hydrazine monohydrate and ammonia solution. The prepared materials were interrogated using ... -
Remote sensing for water resources and environmental management
(Remote Sensing, 2022-12-21)In line with the United Nations Sustainable Development Goal (SDG) 6, the main goal of the Special Issue on “Remote sensing for water resources and environmental management” was to solicit papers from a diverse range of ... -
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 ... -
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 ... -
The timing and tectonic context of Pan-African gem bearing pegmatites in Malawi: Evidence from Rb–Sr and U–Pb geochronology
(Elsevier, 2023)The Pan-African belts of Malawi contain a largely unexplored endowment of gem bearing pegmatites. We present U–Pb in zircon (LA-ICPMS) and Rb–Sr mineral isochron geochronological and isotope data from pegmatites across ... -
Review: Groundwater recharge estimation in northern China karst regions
(SpringerLink, 2022)Reliable estimates of groundwater recharge are crucial for the groundwater resources evaluating and sustainable utilization plans formulating. To protect the precious karst groundwater resources, this paper critically ... -
Characterization of blocks within a near seafloor Neogene MTC, Orange Basin: Constraints from a high-resolution 3D seismic data
(Elsevier, 2023)Submarine mass wasting processes in deepwater settings can incorporate large blocks, which may play a key role in deepwater geological processes and geohazard assessment. However, there is a limited understanding of ... -
Petroleum source rock potential evaluation: A case study of block 11a, Pletmos sub‑basin, offshore South Africa
(Springer, 2023)Among the several existing geochemical methods in hydrocarbon exploration, the technique linking total organic carbon content (TOC) and Rock–Eval pyrolysis is most widely used, largely as a result of its capacity to rapidly ... -
Hierarchical Bayesian geostatistics for C stock prediction in disturbed plantation forest in Zimbabwe
(Ecological Informatics, 2022)We develop and present a novel Bayesian hierarchical geostatistical model for the prediction of plantation forest carbon stock (C stock) in the eastern highlands of Zimbabwe using multispectral Landsat-8 and Sentinel-2 ... -
Scenarios analysis using water-sensitive urban design principles: A case study of the Cape Flats Aquifer in South Africa
(Springer, 2020)A feasibility assessment was undertaken on the application ofwater-sensitive urban design (WSUD) for the Cape Flats Aquifer in Cape Town, South Africa, at the local scale. The study contributes towards the planning of ... -
Sandstone reservoir zonation of the north-western Bredasdorp Basin South Africa using core data
(Elsevier, 2021)This study delineates sandstone reservoir flow zones in the north-western Bredasdorp Basin, offshore South Africa, using conventional core porosity and permeability data. The workflow begins by integrating sedimen- tology ... -

(Springer, 2020)A feasibility assessment was undertaken on the application ofwater-sensitive urban design (WSUD) for the Cape Flats Aquifer in Cape Town, South Africa, at the local scale. The study contributes towards the planning of ... -
Decorum in nature: Impala (Aepyceros melampus melampus) dung middens follow spatial point patterns in Mukuvisi Woodland, Zimbabwe
(Taylor and Francis Group, 2023)Guided by the Optimum Foraging Theory,the Avoidance Concept, and assuming that the impala Aepyceros melampus melampus defecate purposevely at dung middens, we hypothe-sized that the impala’s dung midden locations do not: ... -
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 ... -
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 ... -
From conflict to collaboration: Atewa forest governance
(Taylor and Francis Group, 2023)The problem of forest degradation and loss has become theconcern of many countries. To address this challenge, somecollaborate in sustainable forest management. The mostsuccessful outcomes, however, are observed where ... -
Editor’s message: Building capacity and partnerships towards sustainable utilization of groundwater in Africa
(Springer, 2008)This Editor’s Message advises the international groundwater fraternity of new opportunities in hydrogeological developments in Africa. It is a fact that groundwater plays a vital role in socio-economic and ecological ... -
Hydrological modelling and climate adaptation under changing climate: A review with a focus in sub-Saharan Africa
