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 ... -
Drying of sweet potato tubers using a naturally-ventilated solar-venturi dryer and a hot-air dryer.
(2020)Abstract available in PDF. -
Characterisation of the electrochemical properties of maize grain contaminated with aflatoxin.
(2017)Abstract available in pdf. -
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 ... -
Characterization of flour and starch from Zambian cassava cultivars and application in frozen wheat bread dough.
(2019)Abstract available in pdf. -
The role of decision making and management of construction projects in fostering sustainability for intensive urban development through public housing initiatives in South Africa.
(2018)The current discourse in sustainable development is centred on the 17 Sustainable Development Goals stipulated in the 2030 Agenda for Sustainable Development as well as the New Urban agenda. The resilience, inclusiveness ... -
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, ... -
Breeding dry bean for resistance to bacterial brown spot disease conditions in South Africa.
(2018)Bacterial brown spot (BBS) disease is a major disease in dry beans in South Africa causing yield losses of up to 55%. The overall goal of the research was to improve dry bean production through identifying high yielding ... -
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 ... -
The foliar micromorphology and medIicinal phytochemicalpProperties of Heteropyxis Natalensis (Myrtaceae).
(2018)The use of medicinal plants as a form of therapeutic healing is an ancient tradition in various regions of the world. As a result, there is a dire need to screen medicinal plants for their unrevealed pharmacological ... -
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 ... -
Effects of water deprivation on the prevalence of gastrointestinal parasites in Nguni goats.
(2016)The broad objective of the study was to determine the effects of water deprivation on prevalence of gastrointestinal parasites in Nguni goats. A cross-sectional survey was conducted on 285 farmers that kept goats from ... -
Engineering and water governance interactions in smallholder irrigation schemes for improved water management.
(2019)Smallholder Irrigation Schemes (SISs) in South Africa have reported below expectation performance, despite massive investments. A diagnosis of the SISs poor performance indicates prevalence of infrastructural deficiencies, ... -
Haematological, blood glucose and insulin profile in sprague-dawley rats experimentally infected with trichinella Zimbabwensis and plasmodium berghei anka.
(2017)Malaria and helminth co-infection have been widely reported by other researchers. Despite the increasing knowledge on co-infection, the impact of helminths and malaria on humans and laboratory animal models remains uncertain. ... -
Development of a naturally-ventilated solar energy-assisted maize seed store.
(2018)The seed industry continues to face losses during seed storage, especially in Africa. Moreover, there is high loss of seed viability during storage, mainly due to the poor ventilation in seed storage structures, which ...
