Assessment of agro-ecosystem sustainability across varying scales in South Africa.
(2005)Maize production plays an important socio-economic role in rural communities of the Highveld region of South Africa, yet it is becoming increasingly difficult to produce maize economically with current agricultural policy ... -
An assessment of canopy and litter interception in commercial and indigenous forests in the KwaZulu-Natal Midlands, South Africa.
(2011)Understanding of the hydrological cycle and processes such as interception span as far back as the times of the Renaissance, when Leonardo da Vinci (1452-1519) first described it. However, there remains a gap in the knowledge ... -
Assessment of the water poverty index at meso-catchment scale in the Thukela Basin.
(2006)The connection between water and human wellbeing is increasingly causing concern about the implications of water scarcity on poverty. The primary fear is that water scarcity may not only worsen poverty, but may also ... -
Balancing water for food and environment : hydrological determinants across scales in the Thukela River Basin.
(2008)In this study, geophysical measurements (Electrical Resistivity Tomography-ERT) and remote sensing techniques were applied in the Thukela river basin at various scales to complement the classical hydrometeorological ... -
Challenges in modelling hydrological responses to impacts and interactions of land use and climate change.
(2012)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 ... -
Characterisation of the hydrological processes and responses to rehabilitation of a headwater wetland of the Sand River, South Africa.
(2011)The erosion of headwater wetlands in the Sand River catchment, in the lowveld of north-eastern South Africa has led to a focus on their rehabilitation, both for livelihood security for those that use them for subsistence ... -
Degradation of ecological infrastructure and its rehabilitation for improved water security.
(2018)Abstract available in PDF file. -
Detection and early warning of lightning and extreme storm events in KwaZulu-Natal, South Africa.
(2020)Abstract available in pdf. -
Development and assessment of an improved continuous simulation modelling system for design flood estimation in South Africa using the ACRU model.
(2019)An estimate of the risk associated with flood events is required to adequately design hydraulic structures and limit negative socio-economic impacts as a result of floods. The methods used to estimate design floods in South ... -
Development and assessment of an integrated largescale hydrological modelling tool for water resources management in the Cauvery Catchment, India.
(2022)Economic development and population growth in southern India have resulted in rapid changes to land use, land management and water demand, significantly impacting and degrading water resources. The significant anthropogenic ... -
Development and evaluation of model-based operational yield forecasts in the South African sugar industry.
(2005)South Africa is the largest producer of sugar in Africa and one of the ten largest sugarcane producers in the world. Sugarcane in South Africa is grown under a wide range of agro-climatic conditions. Climate has been ... -
Development of a framework for an integrated time-varying agrohydrological forecast system for southern Africa.
(2007)Policy makers, water managers, farmers and many other sectors of the society in southern Africa are confronting increasingly complex decisions as a result of the marked day-to-day, intra-seasonal and inter-annual variability ... -
Development of a small-scale in-field integrated postharvest citrus treatment unit.
(2016)Abstract available in PDF file. -
Effects of soil carbon and ambient carbon dioxide concentrations on hydrological processes: a modelling study.
(2020)Abstract available in PDF. -
Estimation of catchment response time in medium to large catchment in South Africa.
Abstract and extended abstract available in the print copy. -
Ground and satellite-based assessment of hydrological responses to land cover change in the Kilombero River Basin, Tanzania.
(2013)Changes in land use and land cover are a global issue of concern, especially with regard to possible impacts on biophysical processes which affect the hydrological functioning of a system. Tanzania is no exception to ... -
The hydrological basis for the protection of water resources to meet environmental and societal requirements.
(2006)In common with other natural systems, aquatic ecosystems provide a wealth of economically valuable services and long-term benefits to society. However, growing human populations, coupled with increased aspirations for ... -
Impact of irrigation with gypsiferous mine water on the water resources of parts of the upper Olifants basin.
(2007)The generation of large quantities of mine wastewater in South African coal mines and the needs for a cost effective, as well as an environmentally sustainable manner of mine water disposal, have fostered interests in the ... -
Influence of land cover degradation on the water balance of the Northern Drakensberg high altitude mesic grasslands, South Africa.
(2022)Mountainous regions provide vital ecosystem services, such as water provisions to low land areas. However, these regions are also considered sensitive to the effects of environmental change, due to their high levels of ... -
Integrating hydro-climatic hazards and climate changes as a tool for adaptive water resources management in the Orange River Catchment.
(2012)The world’s freshwater resources are being placed under increasing pressure owing to growth in population, economic development, improved standards of living, agricultural intensification (linked mainly to irrigation), ...
