A new modified spatial approach for monitoring non-perennial river water availability using remote sensing in the Tankwa Karoo, Western Cape, South Africa
(AJOL, 2021)
Non-perennial rivers (N-PRs) make up two thirds of all rivers in South Africa, yet many are ungauged.
Traditionally, it has been assumed that when a flow is recorded, there is water throughout that river. These
assumptions ...
Leveraging Google Earth Engine platform to characterize and map small seasonal wetlands in the semi-arid environments of South Africa
(Elsevier, 2021-07)
Although significant scientific research strides have been made in mapping the spatial extents and
ecohydrological dynamics of wetlands in semi-arid environments, the focus on small wetlands remains a challenge. This is ...
Modeling the geographic spread and proliferation of invasive alien plants (IAPs) into new ecosystems using multi-source data and multiple predictive models in the Heuningnes catchment, South Africa
(Taylor and Francis, 2021)
The geographic spread and proliferation of Invasive Alien Plants (IAPs) into new ecosystems
requires accurate, constant, and frequent monitoring particularly under the changing climate to
ensure the integrity and resilience ...
Effect of landscape pattern and spatial configuration of vegetation patches on urban warming and cooling in Harare metropolitan city, Zimbabwe
(Bellweather Publishing, 2021)
The spatial configuration of vegetation patches in the landscape has implications for the provision of ecosystem services, human adaptation to climate change, enhancement, or mitigation of urban heat island. Until recently, ...
Use of remotely sensed derived metrics to assess wetland vegetation responses to climate variability-induced drought at the Soetendalsvlei wetland system in the Heuningnes Catchment, Western Cape province, South Africa
(Taylor and Francis Group, 2021-11-11)
Wetland vegetation plays an important role in the environmental functioning of wetlands through the provision of ecosystem services, such as food and critical habitat for organisms that live in or near water resources. The ...
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 remote sensing of grass senescence: A review on the challenges and opportunities
(Institute of Electrical and Electronics Engineers, 2021)
Grass senescence estimation in rangeland is particularly
important for monitoring the conditions of forage quality
and quantity. During senescence, grasses lose their nutrients from
the leaves to the root and thereby ...
