The relationship between production performance and governance in smallholder irrigation schemes in Swaziland
(2013-11)Smallholder sugarcane growing is central to rural development and poverty alleviation in Swaziland. The main objective of smallholder sugar cane growing is to reduce poverty through increased household income. This study ... -
RELATIONSHIP BETWEEN STREAM BANK CULTIVATION AND SOIL EROSION IN DEDZA, MALAWI
(2012-10-18)The main objective of this research was to test whether there is a relationship between the extent of stream bank cultivation and the extent of soil erosion. Although stream banks have been cultivated over many years it ... -
Relationships between gully characteristics and environmental factors in the Zhulube Meso-Catchment: Implications for Water Resources Management
(2012-10-29)The objectives of this study were to determine the accuracy of using satellite imagery and Orthophotos in gully identification and to test for significant relationships (p<0.05) between gully characteristics and environmental ... -
A remote sensing based approach to determine evapotranspiration in the Mbire District of Zimbabwe.
(2016-06)Water availability and consumption assessments are important for integrated water resources management. Such assessments are usually hindered by the lack of hydro-meteorological data to close the water balance. Remote ... -
Remote sensing based estimation of evaporation among different land cover types in the Upper-Wami River Basin, Tanzania
(2012-07-31)In Semi-arid Africa, evaporation is the dominant hydrological flux and hence an important component in water resources management. However, it is a challenge to fairly estimate the spatial variation of evaporation ... -
Reservoir Operation Under Different Climate Change Scenarios: Case of Roswa Dam, Bikita District, Zimbabwe.
(2012-07-31)The challenge of maintaining or improving the quality of rural livelihoods against the increasing threat of climate change (CC) and climate variability (CV) calls for the development of robust and tested systems, tools ... -
Reservoir Sedimentation as a function of land use and land cover change
(2012-07-31)In Zimbabwe, sediment load has exceeded normal design limits in many reservoirs, thus reducing storage capacity and shortening their useful life for human benefit. The study sought to investigate the impact of land use ... -
Risk Analysis of Wastewater use in Crop Production: A case of Glen Valley Irrigation Scheme, Botswana
(2012-07-17)The Glen Valley Irrigation Scheme uses treated sewage effluent for crop production, however the potential public health risks associated with wastewater use is of major concern to workers and consumers. This research was ... -
Risk analysis of Wastewater use in Crop Production: A case of Glen Valley Irrigation Scheme, Botswana
(2012-07-13)The Glen Valley Irrigation Scheme uses treated sewage effluent for crop production, however the potential public health risks associated with wastewater use is of major concern to workers and consumers. This research was ... -
The role of Indigenous Knowledge Systems in coping with food security and climate challenges in Mbire District, Zimbabwe
(2013-12)Agriculture is the main form of livelihood in the Mbire District of Zimbabwe. The district lies in Natural Region IV and the average rains are 650 mm per year and experiences frequent droughts and floods. Weather forecasting ... -
Satellite Remote Sensing of Surface water evaporation over Lake Mutirikwi, Zimbabwe
(2012-07-31)Evaporation from large water bodies is an important hydrological parameter as it dominates water balance in arid and semi-arid climates. Small changes in actual evaporation can lead to large changes in surface water ... -
A simple method of characterising Solar Thermal Water Heating Systems (SWHS) and the prediction of thermal and economic performance of the SWHS
(University of Zimbabwe, 2017-09)This research is based on manipulating the Hottel-Whillier-Bliss equation to determine the performance characteristics FRԎα, FRUL and Us of the system by substituting mass flow m̊ in the collector based equation ; m̊cpΔTs ... -
Simulation and Optimization of Utility Interactive Photovoltaic Power Generation in Zimbabwe
(2014-07-21)There is a lot of research being done worldwide in harnessing clean energy, like solar energy and injecting it into existing electricity grids. This project looks at modeling, simulation and optimization of utility ... -
Social valuation of wetlands: A case study of Intunjambili Wetland in Matobo District, Matabeleland South, Zimbabwe
(2015-09)Wetlands have been described as “the kidneys of the landscape, and as “biological supermarkets”. However, more than half of the world`s wetlands have been lost and/or degraded. This has caused alteration of vegetation, ... -
Spatial Soil Erosion Hazard Assessment and Modelling in Mbire District, Zimbabwe: Implications for Catchment Management
(2012-07-13)Soil erosion is a natural geomorphological process resulting from water and land interactions but accelerated to become an environmental hazard by human activities such as clearing of forests for cultivation, poor farming ... -
The spatio-temporal soil moisture variation along the major tributaries of Zambezi River in the Mbire District, Zimbabwe
(2013-10)The livelihoods and subsistence of the largest number of people in Mbire communal areas depends on soil moisture evolving from seasonal floods that is tapped for agriculture. The communities have not realised the full ... -
Technical analysis and subsequent optimization of a Solar Rural Mini Grid: Case of Mashaba PV Mini Grid-Gwanda
(2017)Electric power is a key driver of economic growth and prosperity. But access to electricity remains a distant dream for majority of the population living in the remote and arid areas of developing countries. With the growing ... -
Technical constraints to urban wastewater management in Zimbabwe
(2013-09)In urban areas of Zimbabwe, wastewater management receives less attention than water supply. Wastewater management should promote the recycling and reuse of sewage effluent without causing harm to public health and the ... -
Technical efficiency of sprinkler irrigation in Swaziland: a case study of the Lusip Phase 1 in Lubovane area
(2013-11)The purpose of this study was to assess the technical efficiency of sprinkler irrigation of smallholder sugarcane scheme in the Lubovane area of Swaziland in terms of design parameters, frequency of water application, ... -
Transformation of small-scale artisanal gold mining in Zimbabwe through investment in appropriate technology and promoting the concept of sustainable development: The possibility of industrial small-scale mining
(2008-04)Artisanal gold mining is slowly adopting technology formally used in medium to large size mines and developing it into innovative, specialized equipment tailored to conditions pertaining to remote locations in Zimbabwe. ...
