Understanding Striga occurrence and risk under changing climatic conditions across different agroecological farming systems at local and regional scales122
(University of Western Cape, 2020)The invasion by Striga in most cereal crop fields in Africa has posed an acute threat to food security and socioeconomic integrity. Consequently, numerous technological and research developments have been made to minimize ... -
Hydrocarbon potential of the Prince Albert Formation, Ecca Group in the main Karoo Basin, South Africa.
(University of the Western Cape, 2020)This thesis focusses on the hydrocarbon potential of the Prince Albert Formation in terms of its shale gas potential. Unconventional gas production from hydrocarbon-rich shale formations, known as “shale gas”, is one of ... -
Developing a citizen science framework for water resources protection to facilitate operationalization of resource directed measures at catchment level, South Africa
(University of Western Cape, 2021)Maintenance of water resources protection practice for water availability, uninterrupted water utilization, and for ecosystem integrity is critical for sustainable achievement of resource security for all. Therefore, ... -
Assessing land use-land cover changes and their effects on the hydrological responses within the Nyangores River Catchment, Kenya
(University of Western Cape, 2021)This thesis aimed at contributing knowledge on how the widespread changes in land use/cover resulting from increasing human population and their associated activities, are influencing hydrological responses in a sub-humid ... -
Greywater reuse - An assessment of health and nutritional quality of home gardens produce in rural South Africa
(University of Western Cape, 2021)The majority of rural communities in sub-Saharan Africa are predominantly poor and depend largely on small-scale subsistence farming. To date, various farming mechanisms (e.g. organic farming, crop rotation, agroforestry ... -
The impact of land use and land cover changes on wetland productivity and hydrological systems in the Limpopo transboundary river basin, South Africa
(University of Western Cape, 2021)Wetlands are highly productive systems that act as habitats for a variety of flora and fauna. Despite their ecohydrological significance, wetland ecosystems are under severe threat as a result of environmental changes (e.g. ... -
Acid mine drainage prediction techniques and geochemical modelling: case study on gold tailing dams, West Rand, Witwatersrand basin area, South Africa
