The delta of the river Niger

The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone. The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil. The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate. The delta is a petroleum rich region and has been the center of international concern over extensive pollution which is often used as an example of ecocide. The principal cause is major oil spills by multinational corporations of the petroleum industry.

The Niger Delta, as now defined officially by the Nigerian government, extends over about and makes up 7.5% of Nigeria's land mass. Historically and cartographically, it consists of present day Bayelsa, Delta, and Rivers States. In 2000, however, Obasanjo's regime included Abia, Akwa Ibom, Cross River State, Edo, Imo and Ondo States in the region. ==Demographics of more than 40 ethnic groups including the Igboid people, Ukwuani, Abua, Bini, Ohaji/Egbema, Itsekiri, Efik, Esan, Ibibio, Annang, Oron, Ijaw, Isoko, Ika, Urhobo, Kalabari, Yoruba, Okrika, Ogoni, Ogba–Egbema–Ndoni, Epie Atissa people and Obolo people, are among the inhabitants of the political Niger Delta, speaking about 250 different dialects. Language groups spoken in the Niger Delta include the Igboid languages, Ijaw languages, Ibibio Efik languages, Itsekiri language, Central Delta languages, Edoid languages, and Yoruboid Languages,

The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate. The core Niger Delta later became a part of the eastern region of Nigeria, which came into being in 1951 (one of the three regions, and later one of the four regions). The majority of the people were those from the colonial Calabar, Itsekiri and Ogoja divisions, the present day Ogoja, Itsekiri, Annang, Ibibio, Oron, Efik, Ijaw and Ogoni people. The National Council of Nigeria and Cameroon (NCNC) was the ruling political party of the region. The NCNC later became the National Convention of Nigerian Citizens, after western Cameroon decided to separate from Nigeria. The ruling party of eastern Nigeria did not seek to preclude the separation and even encouraged it. The then Eastern Region had the third, fourth and fifth largest indigenous ethnic groups in the country, which are the Igbo, Ibibio and Ijaw. In 1953, the old eastern region had a major crisis when professor Eyo Ita was expelled from office by the majority Igbo tribe of the old eastern region. Ita, an Efik man from Calabar, was one of the pioneer nationalists for Nigerian independence. The minorities in the region, the Ibibio, Annang, Efik, Ijaw and Ogoja, were situated along the southeastern coast and in the delta region and demanded a state of their own, the Calabar Ogoja Rivers (COR) state. The struggle for the creation of the COR state continued and was a major issue concerning the status of minorities in Nigeria during debates in Europe on Nigerian independence. As a result of this crisis, Professor Eyo Ita left the NCNC to form a new political party called the National Independence Party which was one of the five Nigerian political parties represented at the conferences on Nigerian Constitution and Independence. During this period, schools were shut down completely, and gunfire became a daily occurrence.

Following the civil war, local communities increasingly demanded social and environmental justice from the federal government, with Ken Saro Wiwa and the Ogoni tribe as the lead figures for this phase of the struggle. Cohesive oil protests became most pronounced in 1990 with the publication of the Ogoni Bill of Rights. Indigenous people protested against the lack of economic development, e. g. schools, good roads, and hospitals, in the region, despite all the oil wealth created. They also complained about environmental pollution and destruction of their land and rivers by foreign oil companies. Ken Saro Wiwa and nine other oil activists from Movement for the Survival of the Ogoni People (MOSOP) were arrested and killed under Sani Abacha in 1995.

When long held concerns about loss of control over resources to the oil companies were voiced by the Ijaw people in the Kaiama Declaration in 1998, the Nigerian government sent troops to occupy the Bayelsa and Delta states. Soldiers opened fire with rifles, machine guns, and tear gas, killing at least three protesters and arresting twenty five more. Since then, local indigenous activity against commercial oil refineries and pipelines in the region has increased in frequency and militancy. Recently foreign employees of Shell, the primary corporation operating in the region, were taken hostage by local people. Such activities have also resulted in greater governmental intervention in the area and the mobilization of the Nigerian Army and State Security Service into the region, resulting in violence and human rights abuses. In April 2006, a bomb exploded near an oil refinery in the Niger Delta region, a warning against Chinese expansion in the region. The Movement for the Emancipation of the Niger Delta (MEND) stated: "We wish to warn the Chinese government and its oil companies to steer well clear of the Niger Delta. The Chinese government, by investing in stolen crude, places its citizens in our line of fire." Government and private initiatives to develop the Niger Delta region have been introduced recently. These include the Niger Delta Development Commission, a government initiative, and the Development Initiative, a community development non governmental organization based in Port Harcourt. Uz and Uz Transnational, a company with a strong commitment to the Niger Delta, has introduced ways of developing the poor in the Niger Delta, especially in Rivers State. In September 2008, MEND released a statement proclaiming that their militants had launched an "oil war" throughout the Niger Delta against both, pipelines and oil production facilities, and the Nigerian soldiers that protect them. Both MEND and the Nigerian Government claim to have inflicted heavy casualties on one another. In August 2009, the Nigerian government granted amnesty to the militants; many militants subsequently surrendered their weapons in exchange for a presidential pardon, rehabilitation programme, and education.

Western Niger Delta consists of the western section of coastal South South Nigeria which includes Delta, and the southernmost parts of Edo, and Ondo States. The western (or Northern) Niger Delta is a heterogeneous society with several ethnic groups including the Itsekiri, Urhobo, Isoko, Ijaw (or Izon) and Ukwuani; the Bini, Esan, Auchi, Esako, oral, igara and Afenmai in Edo State; and the Ilaje Yoruba in Ondo State. Their livelihoods are primarily based on fishing and farming. History has it that the Western Niger was controlled by chiefs of the four primary ethnic groups the Itsekiri, Isoko, Ijaw, and Urhobo with whom the British government had to sign separate "Treaties of Protection" in their formation of "Protectorates" that later became southern Nigeria. Central Niger Delta consists of the central section of coastal South South Nigeria which includes Bayelsa, Rivers, Abia and Imo States. The Central Niger Delta region has the Ijaw (including the Nembe Brass, Ogbia, Kalabari people, Ibani of Opobo & Bonny, Abua, Okrika, Engenni and Andoni clans), the Ogoni people (Khana, Gokana, Tai and Eleme), the Etche, Egbema, Omuma, Ogba, Ikwerre, Ndoni, Ekpeye and Ndoki in Rivers State, Abia State and Imo State, who are considered as a sub group of the Igbo ethnic group. Eastern Niger Delta consists of Cross River State and Akwa Ibom State. It has the homogeneous Annang, Efik and Ibibio people.

Nigeria has become West Africa's biggest producer of petroleum. Some per day are extracted in the Niger Delta, with an estimated 38 billion barrels of reserves. The first oil operations in the region began in the 1950s and were undertaken by multinational corporations, which provided Nigeria with necessary technological and financial resources to extract oil. Since 1975, the region has accounted for more than 75% of Nigeria's export earnings. Together oil and natural gas extraction comprise "97 per cent of Nigeria's foreign exchange revenues". Much of the natural gas extracted in oil wells in the delta is immediately burned, or flared, into the air at a rate of approximately 70 million m3 per day. This is equivalent to 41% of African natural gas consumption and forms the largest single source of greenhouse gas emissions on the planet. In 2003, about 99% of excess gas was flared in the Niger Delta, although this value has fallen to 11% in 2010. (See also gas flaring volumes). The biggest gas flaring company is the Shell Petroleum Development Company of Nigeria Ltd, a joint venture that is majority owned by the Nigerian government. In Nigeria, " despite regulations introduced 20 years ago to outlaw the practice, most associated gas is flared, causing local pollution and contributing to climate change." The environmental devastation associated with the industry and the lack of distribution of oil wealth have been the source and/or key aggravating factors of numerous environmental movements and inter ethnic conflicts in the region, including recent guerrilla activity by MEND. In September 2012 Eland Oil & Gas purchased a 45% interest in OML 40, with its partner Starcrest Energy Nigeria Limited, from the Shell Group. They intend to recommission the existing infrastructure and restart existing wells to re commence production at an initial gross rate of of oil per day with a target to grow gross production to of oil per day within four years.

Oil revenue allocation has been the subject of much contention well before Nigeria gained its independence. Allocations have varied from as much as 50%, owing to the First Republic's high degree of regional autonomy, and as low as 10% during the military dictatorships. +Oil revenue sharing formula Year Federal State* Local Special Projects Derivation Formula** 1958 40% 60% 0% 0% 50% 1968 80% 20% 0% 0% 10% 1977 75% 22% 3% 0% 10% 1982 55% 32.5% 10% 2.5% 10% 1989 50% 24% 15% 11% 10% 1995 48.5% 24% 20% 7.5% 13% 2001 48.5% 24% 20% 7.5% 13%

The documentary film Sweet Crude, which premiered April 2009 at the Full Frame Documentary Film Festival, tells the story of Nigeria's Niger Delta.

The Niger Delta is a region of unparalleled ecological richness, characterized by its intricate network of waterways, lush mangrove forests, and diverse ecosystems. However, the serene beauty of this landscape has been damaged by a persistent environmental menace, oil spills. Over the years, the Niger Delta has experienced a series of devastating oil spills, primarily caused by industrial activities related to the extraction and transportation of oil and gas. Due to this high amount of spills, the Niger Delta is considered one of the most polluted areas on Earth. These spills have inflicted severe and continuous damage on the delicate balance of the region's ecosystems. They impact both the environment and the livelihoods of the communities that depend on its resources. Two spills in 2008 and 2009 have been the largest and most harmful by far, collectively lasting for almost 150 days and causing flora death over a span of 393 km2. The extensive network of tidal rivers and mangrove swamps make it even easier for the oil to spread quickly, and the delta becomes a sink, trapping the oil that is not removed. The spills came from a pipeline operated by Shell Petroleum Development Company. In addition to smaller spills that took place over the years 2006–2019, it is estimated that a total of 92,479,170 liters (or 24430412.139 gallons) of crude oil were released into the studied area. This includes organic contaminants such as polycyclic aromatic hydrocarbons, benzene, toluene, ethylbenzene and xylene, as well as heavy metals such as lead, vanadium and cadmium. In fact, according to the Scientific Committee on Health, Environmental and Emerging Risks, more than 1300 different chemicals can be put into the environment as a result of oil and gas exploration. Then, humans come in contact with these harmful substances through eating contaminated food as well as breathing in the air pollution. Polycyclic aromatic hydrocarbons are especially concerning because of their persistence in the environment. Even in low amounts, the prolonged exposure can cause serious health issues such as cancer and other chronic illnesses. Collectively, more than 1 million people live in the area that has been contaminated by oil/gas pollution. This population is especially vulnerable to chronic illnesses because of their pre existing low life expectancy and large ratio of young people. These factors make it increasingly harder for the local communities to deal with the negative effects caused by foreign oil exploration. The people affected by oil spills in the Niger Delta are diverse communities residing in the region. Their lives are intricately connected to the natural environment. These communities, often made up of indigenous groups, rely on the Niger Delta's resources for their food, water, livelihoods, and cultural practices. The impact of oil spills on these communities is multi faceted and extends beyond health problems. Fishing and agriculture are central to the livelihoods of many Niger Delta communities. Oil spills contaminate water sources and farmlands, severely affecting fish stocks and crops. This disruption can lead to food shortages and economic hardship for those dependent on these activities. Another facet of the people's livelihoods is their culture. The Niger Delta's people have strong spiritual and cultural ties to their environment. The harm inflicted on their land and waterways caused by oil spills deeply disrupts sacred sites and interferes with their cultural practices. The loss of these cultural elements contributes to a sense of displacement and identity crisis among the affected groups/communities. Additionally, when communities fight back against the oil industries as an act of protest, violence is often perpetuated. Since the 1990s there has been continuous violence in an effort to give local communities control of the oil in the delta. These acts of violence include kidnapping of foreign oil workers and holding them for ransom, vandalization, and even the blowing up of oil installations.
