Author:Wright, CY; Archibald, S; Garland, Rebecca M; Naidoo, M; Frost, F; Phala, NDate:Sep 2013Solar ultraviolet radiation (UVR) levels are affected by airborne aerosols, such as particles and gases released during biomass burning events. Two large-scale fires in South Africa were identified and selected based on their proximity to ...Read more
Author:Kruger, FJ; Forsyth, GG; Kruger, LM; Slater, K; Le Maitre, David C; Matshate, JDate:Nov 2006The risk associated with vegetation fires (veldfires) in South Africa is substantial, and veldfires cause severe losses to life, property and the environment in most areas of the country. However, this risk has two parts: first, that arising ...Read more
Author:Archibald, S; Nickless, A; Govender, Nicolin; Scholes, RJ; Lehsten, VDate:Nov 2010This study investigates inter-annual variability in burnt area in southern Africa and the extent to which climate is responsible for this variation. We compare data from long-term field sites across the region with remotely sensed burnt area ...Read more
Author:Van Wilgen, BW; Biggs, HCDate:Apr 2011This paper uses five inter-related topics (the management of rivers, fire regimes, invasive alien species, rare antelope and elephants) to assess 15 years of adaptive management in the Kruger National Park (KNP), South Africa. The importance ...Read more
Author:Gandar, MVDate:Oct 1982This report synthesizes information gained from a study of an experimental fire ignited in an 182 ha portion of the Savanna Ecosystem Project study area in early September 1978. Three smaller fires, each covering 1 ha within this area, were ...Read more
Author:Gibson, L; Engelbrecht, Jeanine; Rush, DDate:Sep 2019Increasing global urbanisation is leading to a rise in the number of people living in informal settlements, challenging our ability to achieve sustainable development goals. As a consequence of high building density, inadequate building methods ...Read more
Author:Mathieu, Renaud; Main, Russell S; Roy, DP; Naidoo, Laven; Yang, HDate:Jun 2019Savannahs are mixed woody-grass communities where low-intensity surface fires are common, affecting mostly the grass layer and rarely damaging trees. We investigated the effect of surface fires in a savannah system in the Kruger National Park, ...Read more
Author:Van Wilgen, BW; Biggs, H; O'Regan, SP; Mare, NDate:Apr 2000This paper analyses the fire history of the Kruger National Park (1.9 million ha), South Africa, for different periods in the park's history, where fire protection was followed by prescribed burning and then a 'natural' (lightning) fire policy. ...Read more
Author:Archibald, S; Roy, DPDate:Jul 2009An algorithm for identifying individual fires from the Modis burned area data product is introduced for southern Africa. This algorithm gives the date of burning, size of fire, and location of the centroid for all fires identified over 8 years ...Read more
Author:Buitenwerf, R; Bond, WJ; Stevens, N; Trollope, WSWDate:Feb 2012For the past century, woody plants have increased in grasslands and savannas worldwide. Woody encroachment may significantly alter ecosystem functioning including fire regimes, herbivore carrying capacity, biodiversity and carbon storage ...Read more
Author:Van Den Bergh, F; Udahemuka, G; Van Wyk, BJDate:Jul 2009A new active fire event detection algorithm for data collected with the Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensor, based on the extended Kalman filter, is introduced. Instead of using the observed temperatures of the spatial ...Read more
Author:Kraaij, T; Cowling, RM; Van Wilgen, BW; Schutte-Vlok, ADate:May 2012Fire management practices aimed at biodiversity conservation are often in conflict with hazard reduction requirements. Particularly in protected areas where such conflict of interest exists, the question is asked: what are the ecological ...Read more
Author:McFerren, G; Frost, PDate:May 2009This paper concerns the development of the South African Advanced Fire Information System (AFIS). Researchers describe a use case of wildfires causing electricity transmission lines to be adversely affected. This use case provided the rationale ...Read more
