Developments in the remote sensing of soil erosion in the perspective of sub-Saharan Africa. Implications on future food security and biodiversity
(Elsevier, 2018)The remote sensing of soil erosion has gained substantial consideration, with considerable scientific research work having been conducted in the past, due to technological improvements that have resulted in the release of ... -
The organisation of urban agriculture in Cape Town, South Africa: A social capital perspective
(Taylor & Francis, 2018)This article explores urban agriculture in Cape Town and its organisational forms. Based on a literature review of peerreviewed articles and grey literature, it examines the state of linkages among urban farmers and various ... -
Transformation between phreatic water and soil water during freeze–thaw periods
(MDPI, 2018)During freeze–thaw periods, the exchange between shallow groundwater and soil water is unusually strong and bidirectional, which causes soil salinization and affects the accuracy of water resources assessment. The ... -
Understanding the spatial distribution of eroded areas in the former rural homelands of South Africa: Comparative evidence from two new non-commercial multispectral sensors
(Elsevier, 2018)In this study, we determine the most suitable multispectral sensor that can accurately detect and map eroded areas from other land cover types in Sekhukhune rural district, Limpopo Province, South Africa. Specifically, the ... -
Effect of landcover/land-use changes on water availability in and around Ruti Dam in Nyazvidzi catchment, Zimbabwe
(Water Research Commission, 2018)The aim of this study was to quantify the upstream land-use and landcover changes and assess their effect on Ruti Dam levels and water availability in Nyazvidzi catchment. Remote-sensing techniques, hydrologic modelling ... -
Characterizing the spatio-temporal variations of C3 and C4 dominated grasslands aboveground biomass in the Drakensberg, South Africa
(Elsevier, 2018)C3 and C4 grass species composition, with different physiological, morphological and most importantly phenological characteristics, influence Aboveground Biomass (AGB) and their ability to provide ecosystem goods and ... -
Characterization of macropore structure of Malan loess in NW China based on 3D pipe models constructed by using computed tomography technology
(Elsevier, 2018)Malan loess is a grayish yellow or brownish yellow, clastic, highly porous and brittle late Quaternary sediment formed by the accumulation of windblown dust. The present-day pore structure of Malan loess is crucial for ... -
A synthesis of past, current and future research for protection and management of papyrus (Cyperus papyrus L.) wetlands in Africa
(Springer Verlag, 2014)Papyrus wetlands (dominated by the giant sedge Cyperus papyrus L.) occur throughout eastern, central and southern Africa and are important for biodiversity, for water quality and quantity regulation and for the livelihoods ... -
Water materialities and citizen engagement: Testing the implications of water access and quality for community engagement in Ghana and South Africa
(Taylor & Francis, 2017)We analyze the relationship between perceptions of domestic water access, and quality, in relation community engagement. While others have suggested linkages between material conditions of water access and engagement ... -
Erratum to: Post-orogenic shoshonitic magmas of the Yzerfontein pluton, South Africa: the 'smoking gun' of mantle melting and crustal growth during Cape granite genesis?
(Springer Verlag, 2017)The published version of the original paper contained a Sr isotope analysis of Hornblende-pyroxene quartz monzodiorite sample H25, from the shoshonitic part of the Cambrian Yzerfontein pluton on the West Coast in South ... -
Post-orogenic shoshonitic magmas of the Yzerfontein pluton, South Africa: the 'smoking gun' of mantle melting and crustal growth during Cape granite genesis?
(Springer Verlag, 2017)The post-orogenic Yzerfontein pluton, in the Saldania Belt of South Africa was constructed through numerous injections of shoshonitic magmas. Most magma compositions are adequately modelled as products of fractionation, ... -
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 ... -
Will climate warming exceed lethal photosynthetic temperature thresholds of lichens in a southern African arid region?
(Wiley, 2013)Predicted elevated temperatures and a shift from a winter to summer rainfall pattern associated with global warming could result in the exposure of hydrated lichens during summer to more numerous temperature extremes that ... -
Climate change and its influence on the Karst groundwater recharge in the Jinci Spring Region, Northern China
(MDPI, 2017)Due to climate change and human activities over the last fifty years, the spring flow volume of karst groundwater has sharply diminished in China. Climate change is one of the critical factors that initiates a series of ... -
Effects of land use change on streamflow and stream water quality of a coastal catchment
(South African Water Research Commission, 2017)This study aimed to link land cover/use change to water quality in an important water supply coastal catchment. The approach followed a spatial and temporal analysis of historical catchment land use change to assess how ... -
Emerging forms of social action in urban domestic water supply in South Africa and Zimbabwe
(Canadian Center of Science and Education, 2013)This paper compares and contrasts emerging forms of social action in urban domestic water supply in South Africa and Zimbabwe. Both countries represent transitional societies that are facing challenges of providing clean ... -
Conservation status of large branchiopods in the Western Cape, South Africa
(Springer Verlag, 2007)Temporary wetlands are an ecologically and economically important habitat in South Africa. They harbor large branchiopods, known to be flagship species of nonpermanent aquatic habitats, and sensitive to land use changes. ... -

The role of ground water in Sub-Saharan Africa
(Wiley-Blackwell, 2010)Although water resources managers speak of a water crisis in Africa, the management of ground water has to date not featured strongly in national and regional African water agendas. Examination of the physical environment of ... -
Review: groundwater management and groundwater/surface-water interaction in the context of South African water policy
(Springer Verlag, 2011)Groundwater/surface-water interaction is receiv¬ing increasing focus in Africa due to its importance to ecologic systems and sustainability. In South Africa's 1998 National Water Act (NWA), water-use licenses, including ...
