Pathways of Human Sprawl in Wilderness Buffer Zones
(Population Environment; Springer Netherlands; http://www.springerlink.com/content/0t141ml76q32717m/, 2006-01)
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 ...
Use of remotely sensed data in the analysis of soil-vegetation changes along a drying gradient peripheral to the Okavango Delta, Botswana
(Taylor & Francis; http://www.tandf.co.uk/journals/titles/01431161.asp, 2005-10-10)

The hydrological regime of the Okavango River Basin is the main driver of ecological change in the delta. The delta supports a small-scale fishery which is a source of livelihood for communities within its fringes. The ...
Seasonal variation in energy influxes and carbon dioxide exchange for a broad-leaved semi-arid savanna (Mopane woodland) in Southern Africa
(Blackwell publishing, www.blackwellpublishing.com, 2004)
We studied the seasonal variation in carbon dioxide, water vapour and energy fluxes in a broad-leafed semi-arid savanna in Southern Africa using the eddy covariance technique. The open woodland studied consisted of an ...
