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 ... -
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 ... -
How do we get the community gardening? Grassroots perspectives from urban gardeners in Cape Town, South Africa
(Taylor and Francis Group, 2023)Urban agriculture offers numerous environmental, economic, and socialbenefits. However, it is often hampered by limited engagement in cities of theglobal South. This article offers bottom-up perspectives on how to increasethe ... -
Impacts of groundwater and climate variability on terrestrial groundwater dependent ecosystems: A review of geospatial assessment approaches and challenges and possible future research directions
(Taylor and Francis Group, 2022)Terrestrial groundwater dependent vegetation (TGDV) are crucialecosystems which provide important goods and services such ascarbon sequestration, habitat, water purification and aestheticbenefits in semi-arid environments. ... -
Influence of landscape moisture sources and topography on rock weathering patterns associated with wildfire
(Wiley, 2022)From 9 March 2015, a wildfire burned an area of 25.7 km2, or approximately half of the Jonkershoek catchment (Western Cape, South Africa), over the course of 3 days. During this period, large areas of fynbos and commercial ... -
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 ... -
A multi-proxy provenance study of late carboniferous to middle Jurassic sandstones in the Eastern Sverdrup basin and its bearing on arctic palaeogeographic reconstructions
(MDPI, 2023)A multi-proxy provenance study of Late Carboniferous to Middle Jurassic sandstones from the eastern Sverdrup Basin was undertaken employing optical petrography and heavy mineral analysis, chemical analysis of apatite, ... -
Progress in the remote sensing of groundwater-dependent ecosystems in semi-arid environments
(Elsevier, 2021)Remote sensing of groundwater-dependent ecosystems (GDEs) has increased substantially in recent years. Of significant prominence, is the delineation and mapping of groundwater-dependent vegetation (GDV), species diversity, ... -
Progress in the remote sensing of veld fire occurrence and detection: A review
(Wiley, 2023)Our research provides a detailed overview of the progress in remotely sensed fire monitoring techniques, which have been developed and employed for fire occurrence and detection. Our overview is provided from a literature ... -
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 ... -
Two pulses of Mesoproterozoic intra-plate magmatism in the heart of the Palaeoproterozoic Ubendian Domain of northern Malawi
(Elsevier, 2023)Two Mesoproterozoic anorogenic igneous events are recorded in the Palaeoproterozoic Ubendian Domain in northern Malawi. The oldest is represented by the Mwakikome orthogneiss, a small peraluminous, sub-alkaline and ferroan ... -
Will a rising sea sink some estuarine wetland ecosystems?
(Elsevier, 2016)Sea-level rise associated with climate change presents a major challenge to plant diversity and ecosystem service provision in coastal wetlands. In this study, we investigate the effect of sea-level rise on benthos, ...
