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 ... -
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 ... -
Waste sector small and medium-sized enterprises and their role in the extended producer responsibility; a case study of environmental responsibility in SMEs in eThekwini, KwaZulu-Natal (South Africa).
(2014)Both the waste sector and corporate enterprises, under the banner of corporate social and environmental responsibility (CSER), have a role to play in sustainable development, particularly in the South African context ... -
Enhancing integrated coastal management decision making in KwaZulu-Natal, South Africa through knowledge transfer and information sharing.
(2019)Coastal environments are complex systems being sought-after for a myriad of environmental, socioeconomic and cultural activities, supporting an estimated 44% of the world’s population. The demand for coastal space and ... -
Climatic, environmental and socio-economic factors for malaria transmission modelling in KwaZulu-Natal, South Africa.
(2018)Sub-Saharan Africa (SSA) largely bears the burden of the global malaria disease, with the transmission and intensity influenced by the interaction of a variety of climatic, environmental, socio-economic, and human factors. ... -
Exploring the relationship between spectral reflectance and tree species diversity in the savannah woodlands.
(2018)Abstract available in PDF file. -
Discrimination and biomass estimation of co-existing C3 and C4 grass functional types over time : a view from space.
(2018)The co-existence of C3 and C4 grass species significantly influence their spatio-temporal variations of biochemical cycling, productivity (i.e. biomass) and role in provision of ecosystem goods and services. Consequently, ... -
The ecology of ungulates in the Waterberg Plateau National Park, Namibia.
(2019)Although ungulate species form an important component of Namibia’s economy through tourism, their population sizes vary substantially in relation to irregular rainfall, poaching, predation and competition, amongst other ... -
Restoration of a degraded subtropical forest for climate change mitigation and adaptation in the city of Durban, South Africa.
(2017)With unprecedented changes in climate and land-use patterns, a decrease in global biodiversity and ecosystem services has been occurring at an alarming rate. This has resulted in a widespread damage to the life-support ... -
Climate change responses in urban low-income groups, Pietermaritzburg, KwaZulu-Natal, South Africa.
(2017)South Africa is urbanising at an unsustainable rate such that the levels of urban poverty and inequality are rising, taking the country further from its attainment of the sustainable development goals, mainly, the elimination ... -
Linking thermal variability and change to urban growth in Harare Metropolitan City using remotely sensed data.
(2017)Urban growth, which involves Land Use and Land Cover Changes (LULCC), alters land surface thermal properties. Within the framework of rapid urban growth and global warming, land surface temperature (LST) and its elevation ... -
Modelling spatial variability of coffee (Coffea Arabica L.) crop condition with multispectral remote sensing data.

Climate change learning in an electricity utility: distribution division case study, Eskom, South Africa.
(2018)One of the most significant ways in which humans have damaged the environment is the contribution to rapid global warming which causes major changes to the climate on earth, resulting in many negative impacts to humans ... -
Assessing the invasiveness of alien aroids using modelling techniques and ecological assessments.
(2016)Biological invasions represent one of the main drivers of the present decline in biodiversity worldwide and are difficult and costly to control. Consequently, identifying which factors allow a small proportion of species ... -
A comparative assessment of the socio-economic and spatial factors impacting the implementation of renewable energy in marginalised communities: the case of Inanda and Bergville.
(2016)Access to modern, safe and cost effective energy is undisputed in its ability to facilitate development among poor countries, however, achieving energy security is plagued by challenges. Renewable energies and technologies ... -
