Addressing the need for improved land cover map products for policy support
(Elsevier, 2020-10)The continued increase of anthropogenic pressure on the Earth’s ecosystems is degrading the natural environment and then decreasing the services it provides to humans. The type, quantity, and quality of many of those ... -
Advances in optical earth observation for geological mapping : a Review
(CONSAS Conference, 2016)Recent increases in the availability of earth observation (EO) data and the advances made in its processing have opened up new opportunities for earth monitoring studies. This article reviews recent advances in EO, ... -
An ‘age-regation’ process as theoretical understanding of the gated retirement village
(SUN MeDIA Bloemfontein, 2012-04)Gating the elderly appears to be a common and inevitable part of international urban life. In our study we have used the structure-agency relationship to identify and analyse the salient elements of the process of gating. ... -
Aircraft noise management through controlled-area demarcation in South Africa : its application at Cape Town International airport
(Academy of Science for South Africa, 2005)Aircraft noise is a growing social, technical, economic and environmental problem, especially in developing countries like South Africa. It arises from the growth in air traffic, urbanization, uncoordinated planning around ... -
Ants, altitude and change in the northern Cape Floristic Region
(Blackwell publishing Ltd, 2006)Aim: Climate-modelling exercises have demonstrated that the Cape Floristic Region is highly sensitive to climate change and will apparently lose much of its northern limits over the next few decades. Because there is ... -
The application of an Urban Sprawl Index : comparing towns and cities in the Western Cape Province, South Africa
(CONSAS, 2018)The incidence and effects of urban sprawl have been the subject of a great many academic research mainly as a result of the challenges posed by continued urbanisation, especially in developing countries (see inter alia ... -
Application of geospatial technology for gap analysis in tourism planning for the Western Cape
(Academy of Science of South Africa, 2013)ENGLISH ABSTRACT: We report on the use of modern spatial computing technology in the development of spatial tourism policy and planning in the context of a bounded resource base. We refer briefly to provincial tourism ... -
Applying the water-energy-food nexus to farm profitability in the Middle Breede catchment, South Africa
(Academy of Science of South Africa, 2018)The water-energy-food nexus has emerged as a useful concept to understand the multiple interdependencies that exist between the water, energy and food sectors. The nexus is an ambitious attempt to work across disciplines ... -
Architecture in Southern African informal settlements : a contextually appropriate intervention
(Urbanistični inštitut RS, 2019)Architectural professionals can contribute to efforts at achieving sustainable urbanism. However, the realm of professional discourse is extremely limited. Grounded architectural practice (GAP) is developed as a conceptual ... -
Are the walls giving way to fences? Is racial integration within Kwadukuza municipality leading to income-based class segregation?
(CONSAS, 2017-10)The racial and development imbalances created by apartheid have made a profound impact on the urban and social landscape in South Africa. Despite it being 20 years into the dawn of a new South Africa, many parts of society ... -
Assessing the influence of DEM source on derived streamline and catchment boundary accuracy
(South African Water Research Commission, 2019)Accurate DEM-derived streamlines and catchment boundaries are essential for hydrological modelling. Due to the popularity of hydrological parameters derived mainly from free DEMs, it is essential to investigate the accuracy ... -
Assessment of accuracy : systematic reduction of training points for maximum likelihood classification and mixture discriminant analysis (Gaussian and t-distribution)
(CONSAS Conference, 2018-09)Remote sensing provides a valuable tool for monitoring land cover across large areas of land. A simple yet popular method for land cover classification is Maximum Likelihood Classification (MLC), which assumes a single ... -
A biodiversity monitoring framework for South Africa : progress and directions
(Academy of Science of South Africa, 2007)Global declines in biodiversity, and the associated impacts on human wellbeing, have triggered national and international agreements to reduce or halt these trends. The Convention on Biological Diversity's 2002 commitment, ... -
Biogeographical patterns of endemic terrestrial Afrotropical birds
(Wiley-Blackwell, 2002)Biogeographical zones are described for terrestrial bird species endemic to the Afrotropics using up-to-date distributional data and multivariate statistical techniques. This provides an objective basis for a hierarchy ... -
Business clustering along the M1-N3-N1 corridor between Johannesburg and Pretoria, South Africa
(CONSAS Conference, 2016)As a communication axis between Pretoria and Johannesburg the Old Pretoria Main Road always served as a linear force of attraction of urban development. This force was subsequently strengthened, first by the construction ... -
Catering for large numbers of tourists : the McDonaldization of casual dining in Kruger National Park
(Uniwersytet Mikołaja Kopernika w Toruniu, 2016)Since 2002 Kruger National Park (KNP) has subjected to a commercialisation strategy. Regarding income generation, SANParks (1) sees KNP as the goose that lays the golden eggs. As part of SANParks’ commercialisation strategy ... -
Change detection of bare areas in the Xolobeni region, South Africa using Landsat NDVI
(CONSAS Conference, 2015-06)Identification and protection of areas that are vulnerable to erosion is essential for the conservation of the sensitive wetlands and estuarine ecosystems along the Xolobeni coastal strip. The forecasting ... -
Characteristics of zircon in placer deposits along the west coast of South Africa
(Academy of Science for South Africa, 1999)Mining along the west coast of South Africa is dominated by the exploitation of onshore and offshore diamond deposits. The relatively recent discovery of vast resources of heavy minerals in the area has resulted in the ... -
Characterizing degradation gradients through land cover change analysis in rural Eastern Cape, South Africa
(MDPI, 2017)Land cover change analysis was performed for three catchments in the rural Eastern Cape, South Africa, for two time steps (2000 and 2014), to characterize landscape conversion trajectories for sustained landscape health. ... -
Climate-based regionalization and inclusion of spectral indices for enhancing transboundary land-use/cover classification using deep learning and machine learning
(MDPI, 2021)Accurate land use and cover data are essential for effective land-use planning, hydrological modeling, and policy development. Since the Okavango Delta is a transboundary Ramsar site, managing natural resources within ...
