Résumé
The eastern province of Zambia is made up of two agro-ecological regions, a semi-arid and a sub-humid. Although the land is generally of low agricultural potential in both, the sub-humid region offers better potential. Thus agriculture and the population are mainly concentrated in the sub-humid region. Unsuitable land use types and poor agricultural practices facilitate land degradation in both regions. The higher population density in the sub-humid region means greater pressure on the land there than in the more sparsely populated semiarid region. A consequence is an increased demand for virgin land and hence more new settlements. For people in the sub-humid region, shifting to the more sparsely populated semi-arid region has been a very attractive option. Thus the pressure on land in the semi-arid region is due to demand from within and from the sub-humid region. In this context, the study investigates land degradation in an area highly valued for wildlife conservation in the semi-arid region. The results show inherent poor soil fertility, migration of farmers from the sub-humid areas, soil degradation within short periods of cultivation, and significant loss of natural vegetation closely associated with agricultural land use.
