A STUDY OF WETLAND ENCROACHMENT IN OJO LOCAL GOVERNMENT AREA OF LAGOS, NIGERIA
Abstract
It has been observed in the literature that the conversion of wetlands to other uses has grave consequences on the natural ecosystem in general and on water resources in particular. Despite detrimental impacts observed globally, the encroachment trend has not been abated neither are there deliberate measures in place to control it. This study was carried out to assess the changes that have occurred in the wetlands of Ojo LGA from 1986 to 2016. The area was selected for study because of the rapid rate of urbanization witnessed in the area in the past two decades. Data was obtained using topographical maps and satellite imageries in mapping the extent of encroachment on the wetland area. The Area Analysis method was used to show the trend and rate of land use changes over the period. The results show that there is a marked decline in the areal extent of wetlands. Urban development is however increasing rapidly. The need for further research is also evident.
