Remote sensing of wetland tree species in the iSimangaliso Wetland Park, KwaZulu-Natal, South Africa.
(2016)
The impact of global change is expected to result in changes in the distribution and composition of species. Coastal swamp and mangrove forests are some of the most threatened forest types in the world. Remote sensing is ...
Experiences of a hidden population : life stories of refugees within Pietermaritzburg, KwaZulu-Natal.
(2008)
Refugees, as forced migrants, have suffered displacement under conditions not of their own choosing, rather from a lack of choice, finding themselves in new settings, new places and new hardships. When refugees abandon ...
Integrating remote sensing and geostatistics in mapping Seriphium plumosum (bankrupt bush) invasion.
(2016)
The impacts of plant species invasion in natural ecosystems have attracted geo-scientific studies globally. Several studies have demonstrated that the effects of invasive species can permanently alter an ecosystem structure ...
Estimating foliar and wood lignin concentrations, and leaf area index (LAI) of Eucalyptus clones in Zululand using hyperspectral imagery.
(2006)
To produce high quality paper, lignin should be removed from the pulp.
Quantification of lignin concentrations using standard wet chemistry is
accurate but time consuming and costly, thus not appropriate for a large
number ...
The estimation of Eucalyptus plantation forest structural attributes using medium and high spatial resolution satellite imagery.
(2008)
Sustaining the socioeconomic and ecological benefits of South African plantation forests is challenging. A more systematic and rapid forest inventory system is required by forest managers. This study investigates the utility ...
The impact of a change in climate on small-scale farmers: case studies of the Khokhwane, Sizanenjana and Richmond communities in KwaZulu-Natal, South Africa.
(2016)
A large percentage of land use in South Africa is used for agricultural purposes, as this sector serves as the economic backbone of the country. A change in climate is likely to result in an increase in the frequency and ...
An investigation into estimating productivity, above ground biomass and leaf area index of Eucalyptus grandis using remotely sensed data and a process-based model.
(2007)
South Africa depends largely on afforestation programs for its timber supplies due to the great demands for fiber and wood products. This has brought discomfort to other water users who have advocated that the effects of ...
The planning of Cato Manor: lessons for the sustainable reconstruction of South African cities.
(1995)
This thesis provides an overview of the history of urbanisation in South Africa) showing
how the resultant fragmented) sprawling spatial form serves to degrade the environment as
well as aggravate the plight of the poor. ...
Exploring post-authorisation follow-up and EIA effectiveness in South Africa: case studies from KwaZulu-Natal.
(2016)
Environmental Impact Assessment (EIA) is recognised internationally as a tool for identifying and addressing the potential adverse impacts of a proposed development on the environment. The effectiveness of an EIA depends ...
The use of periphyton and macro-invertebrates and their susceptibility to changes in river flow characteristics and nutrient composition as an indicator of river health.
(2016)
Freshwater systems are a valuable resource under increasing threat due to pollution from activities such as agriculture, industry, mining and domestic use which can pose a risk to human and animal health and may lead to ...
