Dynamics of Land Use/Cover Trends in Kanungu District, South-western Uganda

Like other countries in the sub-saharan africa, uganda is not an exception to the effects of land use/cover changes on the environment. specifically the study intended to; determine the magnitude and trend of land use/cover changes in kanungu district for the last 35 years. a series of landsat tm/etm orthorectified satellite imagery of 1975, 1987 and 1999 were classified using unsupervised classification procedures in ilwis 3.3 software to determine the magnitude and trend of land use/cover changes. a total of 65 local residents were randomly selected for questionnaire administration with the help of village leaders to examine the underlying drivers of land use/cover change. the results showed that the magnitude of small scale (non-uniform) farming largely increased by 5% from 1975 to 1999 while areas covered by tropical high forest relatively decreased by 16% between 1975 and 1987 but slightly increased by 1% in 1999. the areas covered by wetlands comparatively increased by 4% from 1975 to 1987 and by 1999 they slightly decreased by 3%. the woodland areas decreased by 3% from 1975 to 1987 and to some extent also increased by 2% in 1999. household size, type of crops grown, customary land tenure system, availability of agricultural extension workers, weak environmental laws and policies are significant predictors of land use/cover change in kanungu district.
