Case Studies on Coastal Wetlands and Water Resources in Nigeria

Wetlands play a very important role in the sustenance of both the surface andgroundwater resources of the country. It is sad to observe that the country is fast losingher wetlands, as the rich wetlands are being seriously threatened by a number ofanthropogenic and biophysical factors. Some of the notable human actions includepopulation pressure, rapid urbanization, mining, oil and industrial waste pollution,overgrazing, logging, dam construction, transportation routes and other physicalinfrastructure. Others factors are uncontrolled tilling for crop production andunprecedented/unregulated land reclamation. Subsidence, saltwater intrusion, sandstorm, desertification and droughts, invasion by alien floral and faunal species as well asmarine and coastal erosion are natural threats to wetlands in Nigeria. Wetlandsdestruction affects negatively water supply and water resources management. This studyexamines in great detail the fate of wetlands in the face of climate change andrecommends that efforts should be made to accurately document the country’s wetland.The paper therefore suggested sustainable options for wetlands and water resourcesmanagement in Nigeria. This, the paper opined, can be done through the strengtheningof wetlands preservation and conservation regulation, mitigating the effects of climatechange as well as the development of deliberate restoration programmes and policiesaimed at sustaining degraded wetlands in Nigeria.
