(European Commission Joint Research Centre, 2013)An address is a common reference for a multitude of information. In South Africa, multiple address datasets are developed and maintained by various public and private organizations with little or no cooperation on data ...
-
(CONSAS Conference, 2013-06)The paper explores the adoption of ISO 19152, Geographic information -- Land Administration Domain Model (LADM), in the enhancement of the current City of Johannesburg Land Information System (CoJLIS) data model. The CoJLIS ...
-
(MDPI, 2022-10-31)The Miombo woodland is the most extensive tropical woodland in south-central Africa. However, field sample plot data on forest cover changes, species distribution and carbon stocks in the Miombo ecoregion are inadequate ...
-
(MDPI, 2023-03)Land degradation (LD) is a global issue that affects sustainability and livelihoods of approximately 1.5 billion people, especially in arid/semi-arid regions. Hence, identifying and assessing LD and its driving forces ...
-
(MDPI Publishing, 2021-01-20)This study investigated the impacts of cultivation on water and soil quality in the lower uMfolozi floodplain system in KwaZulu-Natal province, South Africa. We did this by assessing seasonal variations in purposefully ...
-
(MDPI, 2021-10)In arid environments of the world, particularly in sub-Saharan Africa and Asia, floodplain wetlands are a valuable agricultural resource. However, the water reticulation role by wetlands and crop production can negatively ...
-
(CONSAS Conference, 2013-08)Accessibility to higher resolution earth observation satellites suggests an improvement in the potential for fine scale image classification. In this comparative study, imagery from three optical satellites (WorldView-2, ...
-
(American Society for Microbiology, 2020-09-17)South African rabies viruses originating from dogs and jackals (canid viruses) are closely related and highlight cross-species transmission events between the two canine species. Rabies due to the canid lyssavirus variant ...
-
(MDPI, 2021-04-23)Rural communities rely on smallholder maize farms for subsistence agriculture, the main driver of local economic activity and food security. However, their planted area estimates are unknown in most developing countries. ...
-
(MDPI, 2023-05)Precise adjustments of farm management activities, such as irrigation and soil treatment according to site-specific conditions, are crucial. With advances in smart agriculture and sensors, it is possible to reduce the ...
-
(Springer, 2023-03)Ecological research has focused on the importance of environmental factors on spatial biodiversity variations and organisation. This is important because of scant conservation resources. We used stepwise backward selection ...
-
(MDPI, 2022-01)Adverse weather is one of the most prevalent sources of risk in agriculture. Its impacts are aggravated by the lack of effective risk management mechanisms. That is why resource-poor farmers tend to respond to weather ...
-
(MDPI, 2021-11-20)An Earth observation system (EOS) is essential in monitoring and improving our understanding of how natural and managed agricultural landscapes change over time or respond to climate change and overgrazing. Such changes ...
-
(MDPI, 2022-09-30)The study of ecosystem services and the valuation of their contribution to human wellbeing is gaining increasing interest among scientists and decision-makers. The setting of this study was a critical biodiversity area on ...
-
(AOSIS Open Journals, 2013-03-15)Agriculture has both direct and indirect effects on the quality of surface water and groundwater and is among the leading causes of water quality degradation, mainly as a result of the excessive use of agrochemicals. Water ...
-
(MDPI, 2023-12)The relationship between plant productivity, measured according to biomass and species richness, is a fundamental focal point in community ecology, as it provides the basis for understanding plant responses or adaptive ...
-
(Wiley, 2023-09)Assessments of species diversity and richness are essential to understand present ecological and biodiversity conditions for effective conservation management strategies. Biodiversity indicators determine rangeland health ...
-
(Frontiers Media, 2023-08-25)There is limited knowledge on how people living in communal areas perceive land use and land cover (LULC) change and the impacts it has on sustainable access to essential ecosystem goods and services. This study used ...
-
(Academy of Science of South Africa, 2012-03)The launch of artificial satellites (as early as in 1957), specifically the launch of the first laser tracked satellite, Beacon-B, in 1964, has provided data sets which have allowed researchers to probe the long to medium ...
-
(Geological Society of South Africa, 2011-12)We investigate the use of distribution functions to characterise the geophysical signals and noise components embedded in the geodetic Very Long Baseline Interferometry (VLBI) data sets across some of the International ...
