(Elsevier B.V., 2024)The Naoli River Basin (NRB), a pivotal agricultural production area in China, is poised to undergo substantial impacts on water resources due to projected climate and land use/cover (LULC) changes. Despite its significance ... -
An integration of local wisdom into a problem-based student book to empower students' conservation attitudes
(Ozgen Korkmaz, 2024)The current state of students' knowledge regarding species diversity, particularly when it comes to endangered local species, is a cause for concern. This problem has resulted in a decline in students' attitudes towards ... -
Provenance response to evolving palaeogeography recorded by carboniferous sandstones in the northern Pennine Basin, UK
(Elsevier B.V., 2024)On the basis of a combination of heavy mineral data, provenance-sensitive heavy mineral indices, garnet major element chemistry, rutile trace element chemistry and zircon U–Pb geochronology, six major changes in sandstone ... -
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 ... -
Effect of different irrigation systems on water use partitioning and plant water relations of apple trees growing on deep sandy soils in the Mediterranean climatic conditions, South Africa
(Elsevier B.V., 2023)All commercial apple fruit (Malus Domestica (Borkh) exported from semi-arid regions are grown under irrigation with drip and micro sprinkler systems being the most widely used. Few studies have directly compared ... -
Fine-scale characterization of irrigated and rainfed croplands at national scale using multi-source data, random forest, and deep learning algorithms
(Elsevier [Commercial Publisher], 2023)Knowledge of the extent and distribution of irrigated and rainfed croplands is critical in providing the necessary baseline data for enhancing agricultural efficiency and making informed policy decisions. Accurately ... -
Evaluating the effects and benefits of cover crops in citrus orchards: a review
(Taylor and Francis Ltd., 2023)Cover crops are used in sustainable agricultural practices to improve soil quality and minimise the effect of climate change, water restrictions and drought. The South African citrus industry produces and exports a diverse ... -
Review: Groundwater recharge estimation in northern China karst regions
(Institute for Ionics, 2023)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 ... -
The Thousand-Pulsar-Array programme on MeerKAT – XIII. Timing, flux density, rotation measure, and dispersion measure time series of 597 pulsars
(Oxford, 2024)We report here on the timing of 597 pulsars over the last four years with the MeerKAT telescope. We provide times of arrival, pulsar ephemeris files, and per-epoch measurements of the flux density, dispersion measure (DM), ... -
The effects of Jurassic igneous intrusions on the generation and retention of gas shale in the lower permian source-reservoir shales of karoo basin, South Africa
(Elsevier B.V, 2023)Shale gas potential of the Whitehill Formation (Permian), Karoo Basin, South Africa is strongly influenced by widespread Jurassic igneous intrusions. A high-resolution organic petrographic and geochemical study is reported ... -
Understanding climate change effects on the potential distribution of an important pollinator species, ceratina moerenhouti (apidae: ceratinini), in the eastern afromontane biodiversity hotspot, Kenya
(Elsevier Ltd, 2023)Monitoring key pollinator taxa such as the genus Ceratina requires precise near real-time predictions to facilitate better surveillance. The potential habitat suitability of Ceratina moerenhouti was predicted in the Eastern ... -

From benthic to floating: phytoplankton dynamics in African freshwater lakes and reservoirs
(Elsevier, 2023)This chapter reviewed phytoplankton communities in African freshwater lakes and reservoirs and further assessed the latitudinal diversity gradient (LDG) which has been used to explain species variations in other taxonomic ... -
Multispectral remote sensing of wetlands in semi-arid and arid areas: A review on applications, challenges and possible future research directions
(Remote Sensing, 2022)Wetlands are ranked as very diverse ecosystems, covering about 4–6% of the global land surface. They occupy the transition zones between aquatic and terrestrial environments, and share characteristics of both zones. Wetlands ... -
Impacts of climate variability and drought on surface water resources in sub-saharan africa using remote sensing: A review
(Remote Sensing, 2022)Climate variability and recurrent droughts have caused remarkable strain on water resources in most regions across the globe, with the arid and semi-arid areas being the hardest hit. The impacts have been notable on surface ... -
