Abstract:

Key enviromental issues in the Niger Delta of Nigeria relate to its oil industry. The Delta covers 20,000 km2 within wetlands of 70,000 km2 formed predominently by sediment deposition.Home to 20 million people and 40 different ethnic groups,this floodplain makes up 7.5% of Nigeria's total land mass. It is the largest wetland and maintains the third-largest drainage area in Africa. The Delta's environment can be broken down into four ecological zones: coastal barrier islands; mangrove swamp forests; freshwaterswamps and lowland rainforest.This incredibly well endowed ecosystem,which contains one of the highest concentrations of biodiversity on the planet,in addition to supporting the abundant flora and fauna,arable terrain that can sustain a wide variety of crops,economic trees and more species of freshwater fish, than any ecosystem in West Africa.
