Environmental issues in the Niger Delta

Petroleum extraction in the Niger Delta has led to many environmental issues.^[2][3] The delta covers 20,000 km² (7,700 sq mi) within wetlands, formed primarily 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,^[4] and is Africa's largest wetland.^[5] The Delta's environment can be broken down into four ecological zones: coastal barrier islands, mangrove swamp forests, freshwater swamps, and lowland rainforests. Fishing and farming are the main sources of livelihoods for majority of her residents.^[6]

The delta is well endowed with natural resources and the surrounding ecosystem contains one of the highest concentrations of biodiversity on the planet. In addition to supporting abundant flora and fauna, arable terrain that can sustain a wide variety of crops, lumber or agricultural trees, and more species of freshwater fish than any ecosystem in West Africa.^[7]

The advent of oil production has also negatively impacted the Niger Delta region due to unprecedented oil spillage which has been ongoing for the past 5 decades making the region one of the most polluted in the world.^[8][9] The heavy contamination of the air, ground and water with toxic pollutants is often used as an example of ecocide.^{[10][11][12][13]} It is estimated that while the European Union experienced 10 incidences of oil spills in 40 years, Nigeria recorded 9,343 cases within 10 years.^[14]

The resultant environmental degradation from gas flaring, dredging of larger rivers, oil spillage and reclamation of land due to oil and gas extraction across the Niger Delta region costs about US$758 million every year.^[15] Regrettably, 75% of the cost is borne by the local communities through polluted water, infertile farmland and lost biodiversity.^[16] The region could experience a loss of 40% of its habitable terrain in the next thirty years as a result of extensive dam construction in the region.
