Use of the geochemical and biological sedimentary record in establishing palaeo-environments and climate change in the Lake Ngami basin, NW Botswana
(Elservier, www.elsevier.com, 2006)
Sediment samples from a continuous 4.6 m profile in the dry bed of Lake Ngami in NW Botswana were analysed for geochemistry and dated using both 14C and TL methods. Certain units in the profile were found to be diatom rich ...
Flooding dynamics in a large low-gradient alluvial fan, the Okavango delta, Botswana, from analysis and interpretation of 30-year hydrometric record
(Hydrology and Earth Systems Sciences, www.hydrology-and-earth-system-sciences.net, 2006)
The Okavango Delta is a flood-pulsed wetland, which supports a large tourism industry and the subsistence
of the local population through the provision of ecosystem services. In order to obtain insight into the influence ...
Water balance and infiltration in a seasonal floodplain in the Okavango Delta, Botswana
(Springer link, http://link.springer.com, 2006)
Water balance in a seasonal floodplain in the Okavango Delta, Botswana was determined for three years (1997–1999). There was no surface outflow, and infiltration to ground water was very large (4.7–9.7 m during 90–175 days ...

Pathways of human sprawl in wilderness buffer zones
(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 ...
Interactions between fire and flooding in a southern African floodplain system (Okavango Delta, Botswana)
(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 ...

(Elsevier Science B.V. Amsterdam; http://www.elsevier.com/wps/find/journaldescription.cws_home/768/description#description, 2006)
Detailed chemical analyses were performed on surface water, groundwater and sediment samples collected from the
Okavango Delta between February and November 2003 in order to examine the distribution and geochemistry ...
