Density and Distribution of Citemene Fields in a Miombo Woodland Environment in Zambia.
/ The Bemba people of northern Zambia practice citemene shifting cultivation. We utilized Landsat satellite images from 1984 and 1992 to map the distribution of citemene fields in those two years and to assess changes in the spatial sustainability of citemene cultivation in a miombo woodland study area. The citemene fields were concentrated within about 5-6 km of roads. Between 1984 and 1992, there was a decrease in the number of fields, and an increase in the average distance from the road. These changes may have been due to the introduction of semipermanent maize farming in the intervening years. The estimated cycle times for woodland utilization may have been long enough to maintain sustainability under traditional citemene cultivation practices. However, cycle times may be too short to maintain sustainability within the woodlands along roads.KEY WORDS: Shifting agriculture; GIS; Sustainability; Citemene; Miombo; Zambiahttp://link.springer-ny.com/link/service/journals/00267/bibs/24n2p273.html
