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 ...
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 ...
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 ...
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, 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 the ...
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 ...
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 ...
