The development of the Water-Energy-Food Nexus Index and its application to the Southern African Development Community.
(2020)This thesis commences with a review of the development and relevance of the water-energy-food (WEF) nexus as a framework for achieving resource security. Based on academic and grey literature it includes an assessment of ... -
Development of updated design norms for soil and water conservation structures in the sugar industry of South Africa.
(2020)Sugarcane in South Africa is grown on wide-ranging soils, sometimes in non-ideal climates and on steep topographies where soils are vulnerable to erosion. A consequence of unsustainable soil loss is reduction in field ... -
Flood disaster preparedness and impacts on rural households: a comparative study of Mwandi District of Zambia and Eastern Zambezi Region of Namibia.
(2019)The Zambezi Basin is considered vulnerable to climate variability as evidenced by the recurrent floods. The increased occurrence and severity of floods in recent years in areas previously not flooded has inundated parts ... -

Object-orientation and integration for modelling water resource systems using the ACRU model.
(2018)Water is a limiting resource in South Africa, with demand in many catchments exceeding supply, necessitating transfers of water between catchments. This situation requires detailed and integrated management of the country’s ... -
Variations in growth yield and metabolities of African ginger (Siphonochilus Aethiopicus) in response to irrigation regimes and nitrogen levels.
(2017)Medicinal plants are valuable natural resources used as traditional medicine and have economic significance. African ginger (S. aethiopicus) (Schweinf.) B.L. Burtt is one of the most important rhizomatous plants, ... -
Computational and numerical analysis of differential equations using spectral based collocation method.
(2019)In this thesis, we develop accurate and computationally efficient spectral collocation-based methods, both modified and new, and apply them to solve differential equations. Spectral collocation-based methods are the most ... -
Modelling of micro-environment inside evaporatively and coolbot cooled stores using computational fluid dynamics models and changes in quality of stored tomatoes.
(2018)The postharvest loss of fresh produce is a global problem, with the tomato fruit being subjected to a 30-50% loss of total production after harvest. The cost and the technicality of modern technology, including mechanical ... -
Value chain analysis and determinants of production and consumption of African leafy vegetables in Limpopo Province of South Africa.
(2018)There has been a decline in the production, utilization and diversity of African leafy vegetables (ALVs) such as cowpea leaves, pumpkin leaves, amaranth, collard greens, mustard greens, etc., which poses a threat to the ... -
Vachellia sieberiana var. woodii a high-altitude encroacher: the effect of fire, frost, simulated grazing and altitude.
(2018)ABSTRACT There is increasing evidence that savannas and grasslands throughout the world are experiencing bush encroachment. The replacement of grassy biomes with woody biomes has serious consequences for net primary ... -
Developing a diagnostic heuristic for integrated sugarcane supply and processing systems.
(2019)Innovation is a valuable asset that gives supply chains a competitive edge. Moreover, the adoption of innovative research recommendations in agricultural value chains and integrated sugarcane supply and processing systems ... -
Investigating the effects of irrigation water management techniques using anaerobic baffled reactor (ABR) effluents for crop production.
(2018)The discharge of treated effluents from anaerobic baffled reactor (ABR) into surface and ground water bodies poses a challenge to the environment and can cause pollution. The need for the optimal use of land without a yield ...
