Development of a connectivity index to assess aquatic macroinvertebrate species vulnerability to thermal change : a case study in KwaZulu-Natal Province.
Connectivity of river systems is a critical ecological component affecting not only the integrity of aquatic systems but also freshwater species’ habitat, community structure, migration and other life activities such as ...
Deep row trenching of pit latrine and waste water treatment works sludge : water and nutrient fluxes in forest plantations.
The deep row trenching of ventilated improved pit-latrine (VIP) and waste water treatment works (WWTW) sludge is a unique alternative cost effective land application method that will prevent odour and health problems and ...
A description, quantification and characterization of hillslope hydrological processes in the Weatherley catchment, Eastern Cape Province, South Africa.
Advances in hillslope hydrology have been numerous in the past two decades. However many of these advances have been highly site specific in nature, without identifying any means of linking processes across different ...
The influence of scale and parent material on hillslope hydrological processes in Kruger National Park.
Semi-arid savannas are dynamic and complex systems controlled by fire, nutrient and water availability where water is the major driving force controlling the biological activity in these systems. Knowledge of hydrological ...
The impacts of future urban growth on streamflow in the Mgeni catchment.
Natural vegetation has been converted to land uses, such as agriculture, commercial forestry and urban use, to meet increasing human demands for food, fuel and shelter. These land use changes modify the surface ...
Mainstreaming adaptation to climate change into decision making in the water sector : concepts and case studies from South Africa.
Abstract available in Pdf file.
Challenges in modelling hydrological responses to impacts and interactions of land use and climate change.
To meet society’s needs for water, food, fuel and fibre the natural land cover throughout the world has been extensively altered. These alterations have impacted on hydrological responses and thus on available water ...
Linkages between selected hydrological ecosystem services and land use changes, as indicated by hydrological responses : a case study on the Mpushini/Mkhondeni Catchments, South Africa.
Nature provides essential services to humans, including climate regulation, water provisioning and regulation. These so-called ecosystem services have economical, societal and environmental value. This research aims at ...
Integrative policy instruments for implementing the National Water Act : a case study of the Mgeni Catchment.
South Africa experienced a paradigm shift with the introduction of the National Water Act in 1998 (NWA). Previously, water resource management was based on a centralized approach. Today, it is framed by the Integrated Water ...
Spatial assessment of optimum and sub-optimum growing areas for selected biofuel feedstocks in South Africa.
Energy production using fossil-based fuels (coal, oil and natural gas) has environmental and health effects that have the potential to endanger human welfare. Escalating oil prices and the contribution of carbon dioxide ...
