Quantitative analysis of the permian sediments of Karoo Basin of South Africa using combined petrophysical and x-ray analytical techniques
(Elsevier Ltd, 2024)This study quantifies the petrophysical parameters and determines the impact of mineralogy on the petrophysical parameters of the Permian sediments of the main Karoo Basin, South Africa. Conventional well logs from KDD-01 ... -
Quantitative study on the changes of Karst groundwater level and hydrochemistry in Jinci spring catchment, Shanxi, China
(Springer Nature, 2020)Since Jinci spring ceased to flow on April 30, 1994, it has never been reflowed, which seriously affects the sustainable utilization of karst groundwater. The purpose of this paper is to provide the basis for the reflow ... -
Radio spectral properties of star-forming galaxies in the MIGHTEE-COSMOS field and their impact on the far-infrared-radio correlation
(Oxford University Press, 2021)We study the radio spectral properties of 2094 star-forming galaxies (SFGs) by combining our early science data from theMeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey with VLA, GMRT ... -
Reconstructing drainage pathways in the North Atlantic during the Triassic utilizing heavy minerals, mineral chemistry, and detrital zircon geochronology
(Geological Society of America, 2021)In this study, single-grain mineral geochemistry, detrital zircon geochronology, and conventional heavy-mineral analysis are used to elucidate sediment transport pathways that existed in the North Atlantic region during ... -

Remote Sensing Grassland Productivity Attributes: A Systematic Review
(MDPI, 2023)A third of the land on the Earth is composed of grasslands, mainly used for forage. Much effort is being conducted to develop tools to estimate grassland productivity (GP) at different extents, concentrating on spatial and ... -
Remote sensing of land use-land cover change and climate variability on hydrological processes in Sub-Saharan Africa: Key scientific strides and challenges
(Taylor and Francis Group, 2022)The impact of land use land cover (LULC) change and climatevariability on water resources poses as a major threat in semi-aridenvironments, especially in the sub-Saharan Africa. Countries insub-Saharan Africa are vulnerable ... -
Remotely sensed applications in monitoring the spatio-temporal dynamics of pools and flows along non-perennial rivers: A review
(Taylor and Francis Group, 2022)Non-perennial rivers (NPRs) account for more than 50% of the world’s river network and their occurrence is expanding. Some rivers that were previously classified as perennial have evolved to be NPRs in response to climate ... -
Remotely sensed c3 and c4 grass species aboveground biomass variability in response to seasonal climate and topography
(Wiley Online Library, 2019)Seasonal climate and topography influence C3 and C4 grass species aboveground biomass (AGB). Climate change further threatens these grasses AGB, thereby compromising their ability to provide ecosystem goods and services. ... -
Remotely sensed data for estimating chlorophyll-a concentration in wetlands located in the Limpopo Transboundary River Basin, South Africa
(Physics and Chemistry of the Earth, 2022)Wetlands in semi-arid regions are highly productive and biologically diverse ecosystems that contribute significantly to livelihood and economic development and play a substantial role in sustaining rural livelihoods. These ... -
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 ... -
Review of in-situ and remote sensing-based indices and their applicability for integrated drought monitoring in South Africa
(MDPI, 2023)The devastating socioeconomic impacts of recent droughts have intensified the need for improved drought monitoring in South Africa (SA). This study has shown that not all indices can be universally applicable at all ... -
Review of the current models and approaches used for maize crop yield forecasting in sub-Saharan Africa, and their potential use in early warning systems
(Physics and Chemistry of the Earth, 2022)Agriculture is the mainstay of many developing economies, and successful production is intricately linked to food security, economic development, and regional stability. Estimates of crop yield for strategic grain crops, ... -
Review: Acid mine drainage (AMD) in abandoned coal mines of Shanxi, China
(MDPI, 2020)Excessive exploitation and massive coal mine closures have brought about extensive goafs in Shanxi where 8780 coal mines have been abandoned in the last 20 years. Acid mine drainage (AMD) poses severe environmental impact ... -
Review: groundwater management and groundwater/surface-water interaction in the context of South African water policy
(Springer Verlag, 2011)Groundwater/surface-water interaction is receiv¬ing increasing focus in Africa due to its importance to ecologic systems and sustainability. In South Africa's 1998 National Water Act (NWA), water-use licenses, including ... -
