Aquatic ecosystem responses to fire and flood size in the Okavango Delta: observations from the seasonal floodplains
Ramberg, L.; Lindholm, M.; Hessen, D.O.; Murray-Hudson, M.; Bonyongo, C.; Heinl, M.; Masamba, W.; Vanderpost, C.; Wolski, P. (Springer, http://www.springer.com, 2010-07-19)The frequency of fires in the Okavango Delta seasonal floodplains peaked at an intermediate frequency of flooding. Floodplains are commonly burnt every 3–5 years. This study showed fundamental changes in ecosystem properties ... -
Assessing the impacts of fire on the vegetation resources that are available to the local communities of the seasonal wetlands of the Okavango, Botswana, in the context of different land uses and key government policies
Tacheba, B.; Segosebe, E.; Vanderpost, C.; Sebego, R. (Wiley online library, onlinelibrary.wiley.com, 2009)The Okavango wetlands in north western Botswana are the most fire-prone environment in Botswana. Most of these fires are anthropogenic. The fires in this environment are thought to impact the environment negatively and ... -
Fire activity on drylands and floodplains in the southern Okavango Delta, Botswana
Heinl, M.; Frost, P.; Vanderpost, C.; Sliva, J. (Elsevier; http://www.elsevier.com/wps/find/journaldescription.cws_home/622855/description#description, 2006-05-08)Satellite imagery derived fire history data for the southern Okavango Delta, Botswana from 1989 to 2003 were used to analyse the temporal and spatial distribution of fires and to assess changes in fire activity. Maximum ... -
Indicators of desiccation-driven change in the distal Okavango Delta, Botswana
Ringrose, S.; Vanderpost, C.; Matheson, W.; Wolski, P.; Huntsman-Mapila, P.; Murray-Hudson, M.; Jellema, A. (Elsevier Ltd; www.elsevier.com/locate/jaridenv, 2007-01)This work seeks to determine whether riparian woody plant variables respond to drying and salinity regimes in the semi-arid distal Okavango Delta, northern Botswana. Structural and compositional variables were obtained ... -
Interactions between fire and flooding in a southern African floodplain system (Okavango Delta, Botswana)
Heinl, M.; Neuenschwander, A.; Sliva, J.; Vanderpost, C. (Springer: http://www.springerlink.com, 2006)A series of 98 satellite images was analysed to reconstruct the fire and flood history of a floodplain system in southern Africa(Okavango Delta, Botswana). The data was used to investigate interactions between fire and ... -
More woody plants? the status of bush encroachment in Botswana's grazing areas
Moleele, N.M.; Ringrose, S.; Matheson, W.; Vanderpost, C. (ScienceDirect, www.sciencedirect.com, 2002)the cattle-dominated grazing areas of Botswana. Bush encroachment species – for instance Acacia tortilis, A. erubescens, A. mellifera, Dichrostachys cinerea, Grewia flava, and Terminalia sericea –are increasing in cover ... -
The Okavango; a river supporting its people, environment and economic development
Kgathi, D.L.; Kniveton, D.; Ringrose, S.; Turton, A.R.; Vanderpost, C.; Lundqvist, J.; Seely, M. (Elsevier; www.elsevier.com/locate/jhydrol, 2006)The Okavango basin comprises the Cuito and Cubango active catchment areas in Angola, in addition to the Kavango's Okavango non-active catchment in northern Namibia and Botswana. The Okavango River water and its ecosystem ... -
Pathways of human sprawl in wilderness buffer zones
Vanderpost, C. (Springer, http://www.springer.com, 2006)Intensification of human sprawl in buffer zones of globally important African wilderness areas is of worldwide concern. The paper identifies two major conflicting (yet potentially reconcilable) pathways of rural sprawl in ... -

Rural livelihood diversification: a household adaptive strategy against flood variability in the Okavango delta, Botswana
Motsholapheko, M.R.; Kgathi, D.L.; Vanderpost, C. (Agrekon, www.aeasa.org.za, 2012)This paper assesses the role of livelihood diversification in household adaptation to flood variability in the Okavango Delta, and locates it within the global discourse on adaptation to climate variability and change in ... -
Satellite based long-term assessment of rangeland condition in semi-arid areas: an example from Botswana
Vanderpost, C.; Ringrose, S.; Matheson, W.; Arntzen, J. (Elsevier, 2010-12-14)A methodology was devised for comparison of generalised range condition over time, irrespective of the nature of original imagery used. It was applied for range condition change mapping throughout Botswana through 1984-2000. ... -
Species diversity of the Okavango Delta, Botswana
Ramberg, L.; Hancock, P.; Lindholm, M.; Meyer, T.; Ringrose, S.; Sliva, J.; Vanderpost, C. (Springer link, http://link.springer.com, 2006)In the Okavango Delta (about 28,000 km2) the number of identified species is 1,300 for plants, 71 for fish, 33 for amphibians, 64 for reptiles, 444 for birds, and 122 for mammals. The local occurrence of different species ... -
Use of image processing and GIS techniques to determine the extent and possible causes of land management/fenceline induced degradation problems in the Okavango area, northern Botswana
Ringrose, S.; Vanderpost, C.; Matheson, W. (Taylor & Francis; http://www.tandf.co.uk/journals/titles/01431161.asp, 1997)Attention worldwide has been focused on the need to assess the appropriateness of land management strategies especially where these occur near sensitive areas of wildlife habitat. This work considers the use of mainly ... -
