    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) Chiloane, Chantel; Dube, Timothy; Shoko, Cletah
    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. Global climate change andanthropogenic impacts on surface water resources have led toincreased competing claims on groundwater resources to meetan exponential water demand for environmental needs, agricul-tural and developmental needs. This has led to the unsustainableexploitation of groundwater resources, resulting in groundwatertable declines, threatening the sustainability of TGDV. It is on thispremise that the review aims to provide a detailed overview onthe progress in remote sensing of TGDV.

    Multispectral remote sensing of potential groundwater dependent vegetation in the greater Floristic region of the Western Cape, South Africa
    (Taylor and Francis Group, 2023) Chiloane, Chantel; Dube, Timothy; Shoko, Cletah
    Groundwater dependent vegetation (GDV) is increasingly threa-tened by the transformation of the natural environment. An under-standing of the nature of GDV at the appropriate scale helps environmental managers make suitable decisions. This study assesses the potential for mapping the distribution of GDV within the Heuningnes Catchment using multispectral remotely sensed data (i.e., Landsat 8 (L8) and Sentinel 2 (S2)), the derived vegetation indices (Normalised Difference Vegetation Index (NDVI) and the Soil-Adjusted Vegetation Index (SAVI)) and in-situ data. The GDV distribution maps were produced by integrating vegetation pro-ductivity, landcover, and topographic layers as GDV indicators.
