Última Pastoralists’ Perception and Ecological Knowledge on Savanna Ecosystem Dynamics in Semi-arid Botswana Ecology and Society Kgosikoma, Olaotswe; Department of Agricultural Research; University of Edinburgh; mfana450@yahoo.com; Mojeremane, Witness; Botswana College of Agriculture; wmojeremane@yahoo.com; Harvie, Barbra A.; University of Edinburgh; barbra.harvie@ed.ac.uk. We investigated vegetation dynamics in relation to livestock grazing as perceived by pastoral farmers in different regions of Botswana. A structured questionnaire was used to collect farmers’ understanding of vegetation changes and causes within three different grazing lands. The pastoral farmers’ description of dominant vegetation differed significantly both at the local and district level, which suggests that rangelands consist of patches dominated by different grasses and woody vegetation.

The different factors perceived by pastoral farmers to cause changes in...
