A spectral unmixing method with ensemble estimation of endmembers : application to flood mapping in the Caprivi floodplain
(MDPI, 2017)The Caprivi basin in Namibia has been affected by severe flooding in recent years resulting in deaths, displacements and destruction of infrastructure. The negative consequences of these floods have emphasized the need for ... -
A simple normalized difference approach to burnt area mapping using multi-polarisation C-band SAR
(MDPI, 2017)In fire-prone ecosystems, periodic fires are vital for ecosystem functioning. Fire managers seek to promote the optimal fire regime by managing fire season and frequency requiring detailed information on the extent and ... -
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 ... -
Quantitative risk analysis using vulnerability indicators to assess food insecurity in the Niayes agricultural region of West Senegal
(AOSIS Publishing, 2017)There is an increasing need to develop indicators of vulnerability and adaptive capacity to determine the robustness of response strategies over time and better understand the underlying processes. This study aimed to ... -
Quantifying the effects of ecological constraints on trait expression using novel trait-gradient analysis parameters
(Wiley Open Access, 2017)Complex processes related to biotic and abiotic forces can impose limitations to assembly and composition of plant communities. Quantifying the effects of these constraints on plant functional traits across environmental ... -
Impact of ecological redundancy on the performance of machine learning classifiers in vegetation mapping
(Wiley Open Access, 2017)Vegetation maps are models of the real vegetation patterns and are considered important tools in conservation and management planning. Maps created through traditional methods can be expensive and time-consuming, thus, ... -
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 ... -
Collaborative risk governance in informal urban areas : the case of Wallacedene temporary relocation area
(AOSIS Publishing, 2017)Community-based disaster risk management (CBDRM) is an emancipatory approach that aims to empower local communities in reducing their own risks. A community risk assessment (CRA) is an essential element of CBDRM, incorporating ... -
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. ...
