Sea Level Rise and its Impact on Ayetoro Community, Ondo State, Nigeria

Abstract

Nigerian coast is low-lying, a 1 to 5m rise in sea level which may result from climate change will have a catastrophic effect on the people in these regions. This study explores how sea level rise has impacted Ayetoro community. Questionnaire survey and focus group discussion were used to elicit information on the socio-environmental impacts of sea incursion on the people of the community. Findings show that the community is facing extinction on account of recurring sea level rise. The community which used to be about 20 km away from the sea now has a larger part of its landmass submerged. Findings also show that the impacts of sea level rise on Ayetoro community falls into four categories namely intensified flooding, increased erosion of shorelines, salt water intrusion into freshwater and decline in coastal biodiversity. This study provides information concerning the impact of sea level rise which is useful for coastal planners and managers to develop a framework for integrated coastal zone management to support sustainable development of the coast in the light of rising sea levels. This must ensure the active involvement of stakeholders at all levels ranging from the government to the community to generate their commitment and support and to identify what actions are most needed.
