The effects of unpaved access roads on runoff and associated water quality within the Seele Estate, New Hanover, South Africa.
(2011)Unpaved forestry roads can significantly affect surface runoff and sediment production, with consequential impacts for stream water quality. The potential impact of road runoff on stream water quality is mitigated by the ... -
The environmental and health status of the Mngeni estuary in KwaZulu-Natal, South Africa.
(2005)Abstract not available. -
Environmental design, crime and vulnerability : a case study of Wentworth.
(2013)Apartheid environmental design and planning was aimed at controlling people rather than emphasising safety and security. This resulted in disadvantaged townships becoming conducive to crime and other social problems. In ... -
Environmental justice and the long-term impacts of large dam projects : a case study of communities displaced by the Inanda dam, Durban.
(2002)Inanda Dam situated near Durban in the Mngeni River, in the province of KwaZulu-Natal was completed in the late 1980s. As a typical large dam of the modern era, one major impact of the dam was the displacement and resettlement ... -
Environmental management in the hotel and lodge sector in KwaZulu-Natal, South Africa.
(2013)The tourism industry has emerged as one of the key economic drivers in Africa and remains as one of the few growth industries in the world. The industry has well-documented, significant socio-economic and environmental ... -
Environmentalism in education - the missing link.
(1989)One of modern society's most pressing problems today is the environment with which it interacts. Though this interaction is inseparable, the environment has been treated as a separate entity. This lack of a symbiotic ... -
Estimating and monitoring the phenological cycle of bracken fern (Pteridium aquilinum) using remote sensing.
(2022)Abstract available in PDF. -
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 ... -
Estimating leaf area index (LAI) of black wattle (Acacia mearnsii) using Landsat ETM+ satellite imagery.
(2003)Leaf area index (LAI) is an important variable in models that attempt to simulate carbon, nutrient, water and energy fluxes for forest ecosystems. LAI can be measured either directly (destructive sampling) or by using ... -
Estimating woody vegetation cover in an African Savanna using remote sensing and geostatistics.
(2008)A major challenge in savanna rangeland studies is estimating woody vegetation cover and densities over large areas where field based census alone is impractical. It is therefore crucial that the management and conservation ... -
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 ... -
Evaluating the potential of WorldView-2's strategically located bands in mapping the Bracken fern (Pteridium aquilinum (L.) Kuhn)
(2014)An understanding of the distribution of the Bracken fern (Pteridium aquilinum (L.) Kuhn) is critical for providing an appropriate management strategy. In this regard, remote sensing can play a critical role in mapping and ... -
An evaluation of hyperspectral and multispectral data for mapping invasive species in an African Savanna.
(2015)Invasive alien plant (IAP) species affects a range of ecosystem types in various regions of the world. Therefore are now considered one of the main phenomena causing global change. Invasive alien plants (IAP’s) cause ... -
An evaluation of the consequences of environmental impact assessments (EIAs) on KwaZulu-Natal's biodiversity targets.
(2012)Abstract not available. -
An evaluation of the periglacial morphology in the high Drakensberg and associated environmental implications.
(1997)Although periglacial research in the high Drakensberg and Lesotho mountains has received growing interest amongst southern African geomorphologists, little detailed, quantitative information was available prior to this ... -
An examination of the natural resource asset base of rural households : a case study of KwaDube, a rural community in KwaZulu-Natal, South Africa.
(2013)The spotlight on rural developed and sustainable livelihoods has increased over the years. Additionally, the importance of natural resources (specifically in poorer contexts and rural areas that have limited infrastructure ... -
Examining the utility of the random ensemble and remotely sensed image data to predict Pinus patula forest age in KwaZulu-Natal, South Africa.
(2010)The mapping of forest age is important for effective forest inventory as age is indicative of a number of plant physiological processes. Field survey techniques have traditionally been used to collect forest inventory data, ... -
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 ...
