Land-use/land-cover change analysis for Ghibe Valley - Ethiopia : 1993-2003. M2
This study (conducted March-May, 2003) shows the 10 years of change in land use after tsetse control in the upper Ghibe Valley of Ethiopia between 1993 and 2003. • An Enhanced Landsat Thematic-Mapper (TM-7) satellite image for February 2003 was acquired, ground-truthed, hand-interpreted and analyzed to compare to previous land-use/ land-cover maps created from Landsat TM imagery for this area from 1993. Expansion of cultivation after tsetse control was exceptionally high, with a 231% increase in the area of land cultivated between 1993 and 2003 in the area where tsetse control has been most consistent and successful. The increase in cultivated area at the other study sites, where tsetse control was intermittent, ranged from 101%-182%. It is plausible that tsetse control has played a significant causal role in this rapid expansion in land use in Ghibe Valley. However, more detailed studies are needed to confirm the relative importance of tsetse control compared to other factors (land policy, intrinsic human population growth, others) in causing the measured changes. The high speed and significant magnitude of expansion of cropland is highly unusual in Africa in the experience of the land-use team at ILRI. Changes in land use in other areas with tsetse control have been slower and less extensive.
