Covering 70,000 sq km (27,000 sq miles) of wetlands, the Niger delta was formed primarily by sediment deposition. It is home to more than 30 million people and 40 different ethnic groups, making up 7.5% of Nigeria’s total land mass.
It used to be an incredibly rich ecosystem that contained one of the highest concentrations of biodiversity on the planet before the oil industry moved to the area.

The Nigerian petroleum resources department estimated 1.89m barrels were spilled into the Niger delta between 1976 and 1996. A United Nations development programme report states there have been a total of 6,817 spills between 1976 and 2001, which account for a loss of 3m barrels of oil.
So far, no real action has been taken by the authorities and oil companies to clean up and renaturalise the delta, and oil spills are still very common. Half of them are caused by pipeline and tanker accidents, while other causes include sabotage (28%) and oil production operations (21%), with 1% of the spills being accounted for by inadequate production equipment.
As a result of the oilfields’ small size, there is an extensive network of above-ground pipelines and flow line between the fields, which allow many opportunities for leaks. Pipelines have an estimated life-span of about 15 years, but many of the ones in the Niger delta have been there for 20 to 25 years.
Another issue in the Niger delta is natural gas flaring. Nigeria flares more natural gas associated with oil extraction than any other country, with estimates suggesting that about 70% of associated gas produced in the country is wasted through flaring, the equivalent of 25% of the UK total natural gas consumption.

I photographed Samson when he was performing. From time to time he and some of his friends organise parties and performances in their local area and beyond. Their masked acts are a mixture of art, entertainment and political action. Joy is the neighbour of one of the group members.
During my trip through the delta, on some occasions we were escorted by local police officers because of the danger of attacks by gangs. In Ughelli, an officer escorted us when we visited people affected by gas flaring.
When we got in contact with people suspected of illegal activity, our producer asked some of his friends to join our ranks to have backup in case the situation turned nasty.
Although gas flaring is discouraged because of its toxicity and contribution to the climate emergency, separating commercially viable associated gas from oil is costly. Therefore, oil companies have been burning off associated gas since oil extraction started in Nigeria in the 1960s.
Gas flaring releases large amounts of methane – which has a high global heating potential – together with carbon dioxide and other greenhouse gas. While flaring in the west has been minimised, in Nigeria it has grown proportionally with oil production.
