Future land cover change scenarios in South African grasslands - implications of altered biophysical drivers on land management
(Elsevier, 2018)Future land cover changes may result in adjustments to biophysical drivers impacting on net ecosystem carbon exchange (NEE), catchment water use through evapotranspiration (ET), and the surface energy balance through a ... -
Fire and life history affect the distribution of plant species in a biodiversity hotspot
(Wiley, 2019)Aim: Species distribution models (SDMs) provide valuable insights into species–environment relationships and potential climate change impacts on diversity. Most SDMs do not account for the role of natural disturbance ... -
Mapping surface water in complex and heterogeneous environments using remote sensing
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Global climate change characterised by rising temperatures and changes in the magnitude and intensity of precipitation is projected to affect the spatial and temporal distribution of land surface water ... -
Remote sensing approach for examining changes in water use in relation to climate variability and land cover change
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Water use related research in Southern Africa is currently critical; this is not only a result of current and projected impacts of climate change on water resources but the growing tension among different ... -
Analysis of the fire hazard posed by petrol stations in Stellenbosch and the extent to which planning acknowledges risk
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The study aimed to investigate the extent to which land-use planning in Stellenbosch, South Africa, considers the fire-risk posed by petrol stations, and the implications for public safety, as well as ... -

(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: On June 7, wildfires began in Knysna and burned along a fire line for 300km, also affecting neighbouring Sedgefield and Plettenberg Bay (Knysna-Plett Herald 2017). The major fires burned between June 7 ... -
Reflections on student tourism research in South Africa
(AfricaJournals, 2017)In South Africa, the tourism system has seen considerable policy attention over the past twenty years. As a consequence, there has been a large body of scholarship tracing its development. Much of this work draws heavily ... -
Extreme 1-day rainfall distributions : analysing change in the Western Cape
(Academy of Science of South Africa, 2017)Severe floods in the Western Cape Province of South Africa have caused significant damage to property and infrastructure over the past decade (2003–2014). The hydrological design criteria for exposed structures and design ... -
Transferability of decision trees for land cover classification in a heterogeneous area
(CONSAS, 2017-04)As the value of accurate land cover becomes more apparent, methods to decrease the costs associated with supervised land cover mapping are investigated. One such method is to use training data captured in one scene and ... -
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 ... -
Understanding distributional responses of vegetation to changes in climate and fire regime in the Cape Floristic Region
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: As evidence of climate change and its impact on biodiversity continues to grow, anticipating and understanding ecological responses to climate change is ever more critical. In fire-prone ecosystems, such ... -
