Spatial clustering of vegetation fire intensity using modis satellite data
(MDPI, 2022)This work analyses the spatial clustering of fire intensity in Zimbabwe, using remotely sensed Moderate Resolution Imaging Spectroradiometer (MODIS) active fire occurrence data. In order to investigate the spatial pattern ... -
Remote sensing for water resources and environmental management
(MDPI, 2023)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 ... -
Understanding seasonal dynamics of invasive water hyacinth (eichhornia crassipes) in the greater letaba river system using sentinel-2 satellite data
(Taylor & Francis Online, 2019)Water hyacinth (Eichhornia crassipes) is one of the most aggressive and lethal free-floating aquatic weed that degrades and chokes freshwater ecosystems and threatens aquatic life. Early detection and up-to-date information ... -
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. ... -
A genetic geomorphic classification system for Southern African palustrine wetlands: Global implications for the management of wetlands in drylands
(Frontiers, 2019)Due to climatic constraints in dryland regions, wetlands usually occur at confluences of flow paths, whether from surface flow, inter-flow or at locations of groundwater discharge. Long-term landscape processes that shape ... -
Strength estimation of evaporitic rocks using different testing methods
(Springer, 2019)Rock strength is defined as the limit of the ability of a rock to resist stress or deformation without breaking. Testing methods recommended by ISRM (International Society of Rock Mechanics) and ASTM (American Standards ... -
Review: Karst springs in Shanxi, China
(Springerlink, 2019)China is one of a few countries in the world where karst is intensively developed and karst water is heavily utilized as water supply sources. Shanxi is such a Province with the largest karst distribution in places in ... -
Spatiotemporal green water dynamics and their responses to variations of climatic and underlying surface factors: A case study in the Sanjiang Plain, China
(Elsevier, 2023)The Sanjiang Plain (SJP), located at the confluence reaches of the Heilong, Songhua, and Wusuli Rivers in Northeast China. his study aimed to quantify the effects of varying climate and land-use/land-cover (LULC) dynamics ... -
A modelling approach to improving water security in a drought-prone area, West Coast, South Africa
(ScienceDirect, 2019)Due to severe droughts and rapid urbanization, Cape Town municipality including small towns along the West Coast of South Africa are facing water shortages. Managed aquifer recharge (MAR) seems to offer a solution to improve ... -

(SpringLink, 2019)Rock strength is defined as the limit of the ability of a rock to resist stress or deformation without breaking. Testing methods recommended by ISRM (International Society of Rock Mechanics) and ASTM (American Standards ... -
Shale-gas potential from Cretaceous succession in South Africa’s orange basin: insights from integrated geochemical evaluations
(Taylor & Francis, 2022)Shale sediments were collected from four Cretaceous stratigraphic units across four explorations well locations in South Africa’s Orange Basin and analysed to determine organic-matter characteristics, such as amount, ... -
Mergers, starbursts, and quenching in the SIMBA simulation
(MNRAS, 2019-07-29)We use the SIMBAcosmological galaxy formation simulation to investigate the relationship between major mergers ( 4:1), starbursts, and galaxy quenching. Mergers are identified via sudden jumps in stellar mass M∗ well ... -
Deeper knowledge of shallow waters: reviewing the invertebrate fauna of southern African temporary wetlands
(Spring Nature Limited, 2018)Temporary lentic wetlands are becoming increasingly recognised for their collective role in contributing to biodiversity at the landscape scale. In southern Africa, a region with a high density of such wetlands, ... -
The Utility of the Upcoming HyspIRI’s Simulated Spectral Settings in Detecting Maize Gray Leafy Spot in Relation to Sentinel-2 MSI, VENµS, and Landsat 8 OLI Sensors
(UWC, 2019)Abstract: Considering the high maize yield loses caused by incidences of disease, as well as incomprehensive monitoring initiatives in crop farming, there is a need for spatially explicit, cost-effective, and consistent ... -
Policy implementation for water resources protection: Assessing spatio-temporal trends of results from process-based outcomes of resource-directed measures projects in South Africa
(MDPI, 2022)Governments are continuously developing strategies for policy implementation toward water resource protection. However, little is known about the practical application of such plans to test their effectiveness in policy ... -
A systematic review on the use of remote sensing technologies in quantifying grasslands ecosystem services
(2022)The last decade has seen considerable progress in scientific research on vegetation ecosystem services. While much research has focused on forests and wetlands, grasslands also provide a variety of different provisioning, ... -
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 ... -
