Abstract

The study investigate land use and land cover change around Eti-Osa coastal zone area of Lagos State, Nigeria for the period of 30years, between 1984 and 2014 using satellite remote sensing (landsat) data to determine the changes that occur within this period and the impact of the changes over the area. The Landsat images reveals four type of classification; mangrove, built-up/bare land, water body and wetland. The built-up area significantly increased over the years, covering 3,870.63ha (13.34%) in 1984and 16,332.66ha (56.3%) in 2014 while percentage cover for Mangrove (vegetation) decreases from 13,729.9ha (49.98%) in 1984 to 2269.7ha (8.3%) in 2014. Water body shows only a marginal decrease of 1,692.18ha (4.8%) between the period of 30years examined while there is marginal increase of 690.39ha (3.9%) in wetland area.
