Satellite based long-term assessment of rangeland condition in semi-arid areas: an example from Botswana
(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. ...

Relationship between small-scale structural variability and simulated vegetation productivity across a regional moisture gradient in southern Africa
(2011-11-23)
The observed variability in vegetation structure within landscapes was used as the basis for model estimates of the range of annual productivity of landscape patches at four sites along a moisture gradient in southern ...
