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 ... -
An experiment in land use mapping in the Three Rivers District, Natal.
(1965)No abstract available. -
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 ... -
Exploring the gendered impacts of ecotourism development in Mabibi, northern KwaZulu-Natal, South Africa.
(2020)In South Africa (SA), and many other countries, tourism is seen as an important industry, if not a panacea, for addressing socio-economic regeneration in poor communities, increasing economic activity, and improving local ... -
Exploring the implementation of Integrated Water Resources Management (IWRM) and Adaptive Management (AM) at a local scale: a case study of the uMngeni Catchment, KwaZulu-Natal.
(2020)Integrated Water Resources Management (IWRM) and Adaptive Management (AM) are internationally recognised approaches to water resource management. IWRM promotes the application of principles such as integration, participation, ... -
Field spectroscopy of plant water content in Eucalyptus grandis forest stands in KwaZulu-Natal, South Africa
(2008)The measurement of plant water content is essential to assess stress and disturbance in forest plantations. Traditional techniques to assess plant water content are costly, time consuming and spatially ... -
A fire management environmental decision support system for the uKhahlamba Drakensberg Park World Heritage Site.
(2011)Fire is a major disturbance force that affects global ecosystems and associated biomes and plays a pivotal role in the determination of ecosystem structure, functionality and dynamics. Anthropogenic environmental disturbances ... -
Foredune formation at Tugela River mouth.
(1998)This study examines foredune evolution along a 2100 m section of coast adjacent to the Tugela River. The foredunes vary in both height and shape along the study area and form the southern most extension of the Tugela ... -
Free basic water implementation in selected rural areas of KwaZulu- Natal and the Eastern Cape.
(2004)Water is both a human right and a valuable commodity. Access to water for the rural poor is an international development concern that has been highlighted by the Millennium Development Goals adopted at the Millennium ... -
From herdsmen to safari guides : an assessment of environmental partnerships at IL Ngwesi, Laikipia district, Kenya.
(2000)This thesis provides an analysis of a community based conservation project in northern Kenya and also considers broader theoretical questions relating to the establishment of successful environmental partnerships. In East ...
