The aim of this research was to assess the effect of land
cover change on erosion risk in Akwa Ibom State, Nigeria
from 1987 when the area was constituted into a state. The
methodology adopted involved the use of remote sensing and
geographic information system [GIS] technologies. Land cover
mapping was carried out using remote sensing techniques.
Based on the Co-ordination of Information on the Environment
(CORINE) model, the GIS technology was used to compile and
integrate all the datasets for erosion risk assessment.
Potential and actual erosion risk maps were produced. These
maps revealed that the area under high erosion risk
increased over the years as a result of changes in land
cover. The study concluded that, with appropriate
modifications, the CORINE model integrated with remote
sensing and geographic information system technologies had
great potentials for producing accurate and cost-effective
erosion risk maps for many areas in Africa.
Keywords: Land cover change, erosion risk, CORINE model.
