Is rural migration a threat to environmental sustainability in southern Burkina Faso?

• There is growing evidence that population pressure Oil the land has become the most intractable problem in the developing Countries where demand for food exceeds the food production capacity of the land. Southern Burkina Faso has experienced rapid Population growth, mostly driven by immigration of fanners. This Study was carried Out in Sissili Province and used satellite images acquired over 31-year period, census and Survey data to capture migration patterns and its impacts oil land use change. Results showed that migrant population which accounted for only 3 per cent in the Study area in 1976 shifted to 57 per cent in 2007. Migrant people were using improved technology to progressively convert forest land to cropland. Cropland increased at an annualized rate of 0.46 per cent to the detriment of the dense forest and woodland which decreased at 0.57 per cent per annum. Population growth was highly correlated with increasing area of cropland (r(2) = 0.95, p = 0.014) and declining dense forest (r(2) = 0.78) and woodland (r(2) = 0.95) covers. It call be concluded that rural migration, driven by the relatively good soil and rainfall conditions in the recipient area, is accounted for deforestation in the study area. If rural migration is not checked, it will seriously degrade the environment. Copyright (C) 2009 John Wiley & Sons, Ltd.
