Factors and impacts of informal settlements residents' sanitation practices on access and sustainability of sanitation services in the policy context of Free Basic Sanitation
(IWA Publishing, 2020)Through the Free Basic Sanitation (FBSan) service policy, many informal settlements in South Africa have been provided with basic sanitation facilities. However, access to these facilities remains challenging for many ... -
Factors influencing sustainability of communally-managed waterfacilities in rural areas of Zimbabwe
(Elsevier, 2017)Sustainability of point water facilities is a major development challenge in many rural settings ofdeveloping countries not sparing those in the Sub-Saharan Africa region. This study was done inZimbabwe to investigate the ... -
Factors influencing the awareness and adoption of borehole-garden permaculture in Malawi: Lessons for the promotion of sustainable practices
(MPDI, 2021)Using wastewater accumulating around rural waterpoints to irrigate community gardens, borehole-garden permaculture (BGP) presents a method of sustainable water management. BGP also presents public health benefits through ... -
Feasibility assessment of the application of groundwater remediation techniques in rural areas: A case study of rural areas in the Soutpansberg region, Limpopo Province, South Africa
(MDPI, 2022)Groundwater contribution towards human health and livelihood depends on the contaminants level in groundwater. Many people in rural communities are being exposed to waterborne diseases resulting from drinking untreated ... -
Feasibility of solar-powered groundwater pumping systems in rural areas of greater Giyani municipality (Limpopo, South Africa)
(MDPI, 2023)Rural areas in Limpopo Province (South Africa) are in urgent need of interventions for safe and secure water supply to adapt to climatic changes and the increased frequency of droughts. A feasibility study was conducted ... -
Fine-scale multi-temporal and spatial analysis of agricultural drought in agro-ecological regions of Zimbabwe
(Taylor & Francis, 2022)This study utilised multi-temporal satellite data to characterize droughts across the five Agro-ecological zones (AEZ) of Zimbabwe at monthly, seasonal, sub-seasonal and annual scales (2000 to 2018) using a combination of ... -

Fracture development and fractal characteristics of overburden rock under repeated mining
(Spinger, 2021)The purpose of this paper is to provide scientific basis for the stability evaluation of overburden rock of repeated mining goaf under the expressway. The objectives of the present study are to reveal the development of ... -
From benthic to floating: phytoplankton dynamics in African freshwater lakes and reservoirs
(Elsevier, 2023)This chapter reviewed phytoplankton communities in African freshwater lakes and reservoirs and further assessed the latitudinal diversity gradient (LDG) which has been used to explain species variations in other taxonomic ... -
From conflict to collaboration: Atewa forest governance
(Taylor and Francis Group, 2023)The problem of forest degradation and loss has become theconcern of many countries. To address this challenge, somecollaborate in sustainable forest management. The mostsuccessful outcomes, however, are observed where ... -
From vagueness to precision: raising the volume on social issues for the water sector
(IWA Publishing, 2013)The paper raises the volume on complex social issues that affect water management. The paper proposes Amartya Sen's capability approach (CA) as a suitable framework against which to consider these complex ideals. This ... -
A genetic geomorphic classification system for Southern African palustrine wetlands: Global implications for the management of wetlands in drylands
(Frontiers, 2019)Due to climatic constraints in dryland regions, wetlands usually occur at confluences of flow paths, whether from surface flow, inter-flow or at locations of groundwater discharge. Long-term landscape processes that shape ... -
Geochemistry and weathering history of the Balfour sandstone formation, Karoo basin, South Africa: Insight to provenance and tectonic setting
(Elsevier, 2018)Geochemical analysis on sandstones from clastic sediments was carried out to understand the tectonic setting and subsequent post-depositional change in the Karoo basinal fill of the fluvial deposits of the Balfour Formation ... -
GIS-based modelling of climate variability impacts on groundwater quality: Cape Flats aquifer, Cape Town, South Africa
(Elsevier, 2021)The need to improve groundwater security remains critical, especially in urban areas where demand for groundwater as an alternative source of water supply is increasing following unprecedented population growth. Climate ... -
Groundwater discharges to aquatic ecosystems associated with the Table Mountain Group (TMG) aquifer: a conceptual model
(Water Research Commission, 2008)This paper reports on a conceptual model that was developed to describe the different groundwater discharge ‘types’ from the Table Mountain Group (TMG) aquifer, that contributes to the different components of the flow ... -
Groundwater management issues in Southern Africa – An IWRM perspective
(Water Research Commission, 2008)In contrast to its strategic role as essential resource to help achieve community development and poverty alleviation in the Southern African Development Community (SADC), groundwater has remained a poorly understood and ... -
Hierarchical Bayesian geostatistics for C stock prediction in disturbed plantation forest in Zimbabwe
(Ecological Informatics, 2022)We develop and present a novel Bayesian hierarchical geostatistical model for the prediction of plantation forest carbon stock (C stock) in the eastern highlands of Zimbabwe using multispectral Landsat-8 and Sentinel-2 ... -
High power asymmetric supercapacitor based on activated carbon/reduced graphene oxide electrode system
(Elsevier, 2023-02-22)We synthesized Graphene oxide (GO) using the modified Hummers method and further reduced to reduced graphene oxide (rGO) using hydrazine monohydrate and ammonia solution. The prepared materials were interrogated using ... -
