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 ...
Ecosystem engineering by hummock-building earthworms in seasonal wetlands of eastern South Africa: Insights into the mechanics of biomorphodynamic feedbacks in wetland ecosystems
(Wiley, 2018)
This paper resolves the origin of clay hummock micro-topography in seasonal wetlands of the Drakensberg Foothills,
providing a review and appraisal of previously-suggested mechanisms of hummock formation in the context ...
Foreword to special section: groundwater in Africa
(Wiley-Blackwell, 2010)
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 ...
Deeper knowledge of shallow waters: reviewing the invertebrate fauna of southern African temporary wetlands
(Spring Nature Limited, 2018)
Temporary lentic wetlands are becoming
increasingly recognised for their collective role in
contributing to biodiversity at the landscape scale. In
southern Africa, a region with a high density of such
wetlands, ...
Investigating changes over time of annual rainfall in Zimbabwe
(Copernicus Publications, 2010)
There is increasing concern in southern Africa
about the possible decline of rainfall as a result of global
warming. Some studies concluded that average rainfall in
Zimbabwe had declined by 10% or 100 mm during the ...
Influence of termites on the soil seed bank in an African savannah
(Wiley, 2018)
In savannah ecosystems, termites drive key ecosystem processes, such as primary
production through creation of patchiness in soil nutrients availability around their
nests. In this study, we evaluated the role of termites ...
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, ...
A conceptual model for the development and management of the Cape Flats aquifer, South Africa
(Water Research Commission, 2010)
This paper provides an integrated approach to the analysis of the geological, hydrological and hydrogeological characteristics
of the Cape Flats: a coastal plain sand formed within the mountains of the Cape Town metropolitan ...
