Big oil spills are common in the Niger Delta where over 40 million liters of crude oil is spilled annually, resulting in human deaths and damage to the local ecosystem.
A 2018 study by the Journal of Health and Pollution found that more than 12,000 oil spill incidents have occurred in the oil-rich region between 1976 and 2014.
Pipeline corrosion and tanker accidents caused more than 50 percent of them. Other incidents can be attributed to operational error, mechanical failure, and sabotage mostly from militant groups, the study said.
Contaminated lands, water
The Niger Delta is a diverse region with rich mangroves and fish-rich waterways. Many residents try to make their livelihoods from fishing and farming.
Yamaabana Legborsi lives in Gokana in Ogoni, the most affected community, where residents have stopped oil companies from pumping oil from their lands.
The 32-year-old told CNN growing up the community posed both mental and economic challenges to him as a child.
“We could not play in the sand like other children else you are covered in black crude. My mother was especially worried it was not safe, so were other parents.
“We could not also eat the fishes that washed away from the river, you would see crude all around the water,” Legborsi said.
The situation has not changed, Legborsi says, despite promises from oil companies clean things up.
“I cannot drink water from my borehole. You can perceive crude oil and kerosene. Many of the residents here drink well water, that is contaminated too,” he added.
Experts from the United Nations Environment Programme, (UNEP) in the first scientific survey of the area found that people in Ogoniland had “lived with chronic oil pollution throughout their lives.”
UNEP researchers in the 2011 report said it would take 30 years to clean the oil mess left behind.
Oil companies expected to clean up spills within 24 hours under Nigerian law have also been accused of falling short of this obligation.
In a 2018 report, Amnesty International accused Shell and Eni, the two major operators in the Niger Delta, of negligence in their response to oil spills in the area.
The campaign group said the companies’ “irresponsible approach” to oil spills had worsened the environmental crisis in the Niger Delta, an allegation both companies have since denied.
Shell in an emailed statement to CNN last year said the report failed to acknowledge the complex environment in which the company operates in the region.
“Shell Petroleum Development Company of Nigeria, in collaboration with government regulators, responds to spill incidents as quickly as it can and cleans up spills from its facilities regardless of the cause. We regularly test our emergency spill response procedures and capability to ensure staff and contractors can respond rapidly to an incident,” Shell said at the time.
The response time to an oil spill depends on the security situation and the company’s ability to access affected areas in the swampy region, the company said.
