Assessment of microbial contamination of groundwater in upper Limphasa River catchment, located in a rural area of northern Malawi
(Water Research Commission, 2012)In rural Africa, scientific evidence is often lacking to guide the scaling-up of groundwater as the safest source of potable water. An investigation was conducted in the Upper Limphasa Catchment in northern Malawi to ... -
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 ... -
Salinity of irrigation water in the Philippi farming area of the Cape Flats, Cape Town, South Africa
(Water Research Commission, 2013)This paper explores the nature, source and spatial variation of the salinity of water used for irrigation in a coastal urban farming area in Cape Town, South Africa, where water from the Cape Flats aquifer is drawn into ... -
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 ... -
Application of the rainfall infiltration breakthrough (RIB) model for groundwater recharge estimation in west coastal South Africa
(Water Research Commission, 2013)Recharge estimation in arid and semi-arid areas is very challenging. The chloride mass balance method applied in western South Africa fails to provide reliable recharge estimates near coastal areas. A relationship between ... -
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 ... -
On the use of electrical resistivity methods in monitoring infiltration of salt fluxes in dry coal ash dumps in Mpumalanga, South Africa
(Water Research Commission, 2013)One of the principal environmental concerns relating to coal combustion waste disposal is the potential for groundwater contamination from salt fluxes and trace elements that may be leached into the underlying groundwater ... -
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 ... -
Hope as a critical resource for small scale farmers in Mpumalanga
(SAGE, 2015)I contrast formal institutional structures that are part of water resources management policy and practice with more fluid ‘outside’ spaces that I claim are more apt for participatory engagement around food production. ... -
Assessing the relationship between youth capabilities and food security: A case study of a rainwater harvesting project in South Africa
(AJOL, 2015)Rainwater harvesting presents a viable option for securing water availability in order to increase food production. The study focuses on rural youth in Luphisi and Dwaleni villages in the Mpumalanga Province and considers ... -
New insights in the evaluation of reserves of selected wells of the Pletmos Basin offshore South Africa
(One Petro, 2016)The area evaluated has similar structural styles and settings as the producing neighboring fields of F-A and E-M in the adjacent Bredasdorp basin Offshore South Africa. The main objective of this study is to create a ... -
Will a rising sea sink some estuarine wetland ecosystems?
(Elsevier, 2016)Sea-level rise associated with climate change presents a major challenge to plant diversity and ecosystem service provision in coastal wetlands. In this study, we investigate the effect of sea-level rise on benthos, ... -
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, ... -
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 ... -
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 ... -
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 ... -
An overview of trace elements in soils of Keana-Awe Brine-Fields, Middle Benue Trough, Nigeria
(Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2017)The objective of this study was to determine the concentration of trace elements in soils of Keana-Awe brine-fields. Composite soil samples were randomly collected at a depth of 0–15 cm and were analysed for molybdenum, ... -
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 ... -
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 ...
