Efficacy of morphological approach in the classification of urban land covers.
(2020)Understanding the often-heterogeneous land use land cover (LULC) in urban areas is critical for among others environmental monitoring, spatial planning and enforcement. Recently, several earth observation satellites have ... -
Urban sustainability and social ecological systems: linking civic ecology, nature and ecosystems services for the achievement of the SDGs.
(2021)To address global environmental change and ensure well-being, an improved understanding of complex human-environment relationships is needed. It further requires that the role of natural systems and ecosystem services ... -
UAV and field spectrometer based remote sensing for maize phenotyping, varietal discrimination and yield forecasting.
(2020)Maize is the major staple food crop in the majority of Sub-Saharan African (SSA) countries. However, production statistics (croplands and yields) are rarely measured, and where they are recorded, accuracy is poor because ... -
A spatially explicit approach for analysing the landscape pattern of urban vegetation using remotely sensed data and its impacts on urban surface temperature.
(2020)The landscape pattern of urban green spaces and vegetation plays a significant role in supplying essential benefits and ecological services including sequestering and storing carbon, purification of air and water, ... -
Cities as hotspots for invasions: the case of the eThekwini Municipality.
(2019)Increased anthropogenic activities (trade and travel) have caused an increase in the introduction of biological organisms outside of their native range. Biological invasions result in serious negative ecological, economic ... -
Implications of land use practices and socio-hydrological vulnerability within a rapidly developing city: a case study of the Umhlatuzana River, Ethekwini, South Africa.
(2020)Anthropogenic actions affect land uses and land use change concomitantly influencing water quality in a catchment. In a catchment varying levels of income and access to infrastructure and resources result in a lack of ... -
The application of geographic information systems (GIS) to armed violent conflicts resolution in the Great Lakes region (GLR) of Central and East Africa.
(2020)Armed violent conflict is a persistent global problem, and its severity is more prominent in developing countries, including Africa. In the past decades and more recently, the GLR in east Africa has experienced various ... -
An assessment of visitor profiles, consumption patterns and perceptions as well as the state of coastal and marine tourism (specifically beach) sites in KwaZulu-Natal Province, South Africa.
(2021)Coastal and Marine Tourism (CMT) is the main sub-sector of tourism and has substantial socio-economic and environmental importance. Specifically, CMT is a key economic contributor as well as creating opportunities for ... -
Regional representativeness hotspots for world's tetrapod vertebrate genera.
(2021)As anthropogenic stress and resulting habitat degradation put pressure on biodiversity, there is a need for urgent and innovative conservation strategies. The integration of the biogeographical concept of bioregionalisation ... -
A multi-criteria approach to decision making concerning environmental planning issues within decentralised government institutions.
(2000)Abstract available in PDF. -
Modeling and explaining the distribution of Lantana camara in South African savanna ecosystems.
(2019)Globally, the Invasive Alien Plant (IAPs) species pose a great threat to global biodiversity, agro-ecological systems and socio-economic development. In particular, Lantana camara (L. camara) is amongst the most notorious ... -
Multi-date remote sensing assessment of invasive Lantana camara species distribution in semi-arid savanna rangelands of South Africa.
(2019)Invasive alien species pose a massive threat to biodiversity globally. A comprehensive analysis of the spatial distribution of invasive species, like Lantana camara, is essential for providing appropriate management ... -
The integration of biodiversity in local land-use planning: Gert Sibande District Municipality, South Africa.
(2020)Twenty-five years after the Convention on Biological Diversity (CBD), much emphasis has been placed on the integration of biodiversity priorities and concerns into the development sectors. South Africa has made substantial ... -
The use of machine learning algorithms to assess the impacts of droughts on commercial forests in KwaZulu-Natal, South Africa.
(2020)Droughts are a non-selective natural disaster in that their occurrence can be in both high and low precipitation areas. However, this study acknowledged that droughts are more recurrent and a regular feature in arid and ... -
The utility of Sentinel-2 MSI to assess wetland vegetation chlorophyll content and leaf area index in wetland areas in Pietermaritzburg, KwaZulu-Natal.
(2020)Wetland ecosystems are being modified and threatened due to anthropogenic activities and climate change, hence the urgent need for wetland restoration. Wetland rehabilitation is important in the reversal of these dire ... -
People's perceptions of flood hazards and their attitudes towards resettlement: a case study of the community of Azalea in the Greater Edendale Complex, KwaZulu-Natal, South Africa.
(1997)The thesis addresses flooding as a natural disaster which has, on occasions, occurred in many parts of South Africa, especially in KwaZulu-Natal and Orange Free State. The prevailing impression is that the flood ... -
Towards an understanding of the social learning dynamic in the advancement of rhinoceros anti-poaching in the iMfolozi Game Reserve.
(2012)In the iMfolozi Game Reserve, illegal rhinoceros killings have increased by an order of magnitude since 2007 when only 1 rhinoceros was poached. In the years since then 6 were killed in 2008, 10 in 2009, 14 in 2010 and 9 ... -
Sources of soil erosion in the Hazelmere catchment KwaZulu-Natal, South Africa.
(2002)Sedimentation of reservoirs is of major concern, particularly in South Africa where water resources are scarce. When a reservoir is filled with sediments, it is not only the water storage capacity which is reduced but ...
