Climate Change To Cost Nigeria $460bn By 2050-Expert
The Director, Centre for Climate Change and Development at the Alex Ekwueme Federal University, Ebonyi State, Prof. Chukwumerije Okereke, has said that climate change would cost Nigeria about $460 billion by 2050 if action was not taken to mitigate its effects.
Okereke disclosed this in an interview with newsmen on the sidelines of the ninth international Lagos Climate Change Summit in Lagos.
“Climate change is costing Nigeria already $100 billion per annum. And that this amount will rise to about $460 billion per annum by 2050.
“And this represents a huge amount of our Gross Domestic Product (GDP).
“From 2020 till now, climate change is already costing N15 trillion, representing two to 11 per cent of the GDP, by 2050 climate change will be costing N69 trillion, representing six to 30 per cent of the GDP,” Okereke said.
The expert, who is also a visiting professor to Oxford University, said climate change was already having untold effect on flooding and rising sea levels in the country.
According to Okereke, flooding is already affecting 25 million people in Nigeria.
“In Yenegoa, there are 302,782 people estimated to be exposed to high flood risk along the Niger-Benue basin in the Niger Delta area with 630km of land susceptible to flooding.
“In Lagos, 375,000 people are exposed to flooding; the number will increase to about 3.2 million people by 2050.
“The direct estimate of damage and loss is N1.48 trillion. The total damage and loss, including indirect ones due to flooding is about N2.6 trillion,” Okereke said.
He said that with the rise in sea level, an estimated 27 to 53 million people in the country might need to be relocated with a 0.5m increase in sea levels.
Okereke said that coastal settlements like Bonny, Forcados, Lagos, Port Harcourt, Warri and Calabar were at risk with vast amount of oil infrastructure.
He noted that the country had mapped out a lot of interesting policies to mitigate the effects of climate change.
Okereke listed the policies as long-term sustainability plan to achieve a net zero emission target by 2060 and determined contribution to aggressively embark on actions to mitigate the impact change.
“All these are very fascinating, interesting policies.
“However, the action on the ground does not come anywhere near what is needed to arrest the situation to address the impact of climate change and to also reduce emissions from economic wide activity.
“So, we have a situation where we have a lot of various policies, documents, but very limited action on the ground and this worries me because I have been shouting that climate change poses an existential threat to Nigeria,” Okereke said.
He urged the government to match action with the right policies to achieving the desired result.
“We need to inject a lot of finance and a lot of action to stem the problem of climate change,” Okereke said.
He noted that the impact of climate change on our agricultural system was extremely high.
Okereke said that many Nigerians engage in one kind of agricultural activity or the other and agriculture constitutes about 26 per cent of the nation’s GDP.
“With climate change, you will have drought and it will affect different crops and impose even stronger, negative implications on food security system in the country.
“I have also argued that the depletion of the groundwater around the country caused by climate change and movement of people from the north to the south thereby fuelling insecurity.
“So, you have desertification in the north, flooding in the West, you have erosion in the east and deforestation in the south.
“And all of these things are threatening the existence and the wellbeing of millions of Nigerians,” Okereke said.
Strategic regulators and other stakeholders have expressed satisfaction with the pace, quality and magnitude of work carried out by the Hydrocarbon Pollution Remediation Project (HYPREP) in Ogoniland, in line with the recommendations of the United Nations Environment Programme (UNEP).
In their separate speeches at the 2025 4th quarter key regulators / asset owners meeting held in Port Harcourt, the strategic stakeholders commended HYPREP for the significant milestones achieved with excellent efficiency and transparency, demonstrating capacity and commitment to sustaining collaboration with development partners for the overall success of the Project.
The regulators particularly lauded HYPREP for the landmark success in the implementation of the land and shoreline remediation, mangrove restoration, provision of reticulated potable water, the various sustainable livelihood programmes, donation of ambulances to health facilities in Ogoni, the construction of Centre of Excellence for Environmental Restoration, as well as the ongoing Ogoni Power Project, adding that their independent field reports have shown proofs of HYPREP driving even beyond its mandates.
The goodwill messages were made by representatives of the National Oil Spill Detection and Response Agency (NOSDRA), Centre for Environment and Human Rights Development (CEHRD), Society for Women and Youths Affairs (SWAYA), Stakeholders Democracy Network (SDN), Nigerian Pipelines and Storage Company (NPSC), and Federal Ministry of Environment. Others are the Rivers State Ministry of Environment, the Rivers State Ministry of Health, the National Upstream Petroleum Regulatory Commission (NUPRC), the Rivers State Ministry of Power, the Rivers State University, the Rivers State Ministry of Water and Rural Development, and Renaissance Africa Energy Company Limited.
Following the Monitoring and Evaluation Unit’s presentation on the status of HYPREP projects, participants offered feedback on areas of concern. They reassured HYPREP and the people of Ogoni of their continued support for the Project’s success. They also suggested that the quarterly review meeting be sustained as it enables them to report, evaluate and proffer solutions to areas of concern.
Participants also commended HYPREP for improved community and stakeholder engagement and for adding to what they saw the previous time. “We commend HYPREP for the quality work done at sites. The progress is phenomenal, because HYPREP is scoring good grades, above average,” Prof. Iyenemi Kakulu from Rivers State University said.
In his speech at the event, the Project Coordinator of HYPREP, Prof Nenibarini Zabbey, who was represented by Prof Damian-Paul Aguiyi, Director of Technical Services, commended the regulators and asset owners for their cooperation with the Project, and for making themselves available for fieldwork and the regular review meetings.
Prof Zabbey reiterated HYPREP’s commitment to best practice in waste management, particularly waste generation and disposal, calling on the Regulators for adequate logistics support, saying HYPREP’s priority is to focus on the core recommendations by UNEP, especially, remediation(soil, shoreline) mangrove restoration, provision of potable water, interventions in public health care services and sustainable livelihood for the people.
The Project Coordinator further highlighted the status of the Project, the successes achieved across all thematic areas, and assured that HYPREP will soon complete most of the ongoing projects and roll out others. He explained that the purpose of the meeting was to review the progress of the Ogoni cleanup, ensure quality control, and foster effective collaboration.
Consequently, the quarterly key regulators/asset owners meeting is HYPREP’s strategic stakeholder management model, further underscoring the Project’s commitment to transparency, partnership for development, and accountability, all of which are harbingers of effective project delivery.
Speaking to newsmen, HYPREP Project Support Lead and representative of Renaissance Africa Energy Company Limited, Engr Ehioze Igbinomwanhia, described his involvement with HYPREPas an encouraging and insightful experience, saying, the Project is implementing a wide range of projects across Ogoniland, spanning immediate remediation works as well as livelihood support initiatives aimed at improving the welfare of affected communities.
Engr Igbinomwanhia emphasised that Renaissance Africa Energy remains fully committed to supporting the objectives of the Ogoni cleanup project, noting that the company has a long history of collaboration with HYPREP.
He added that the partnership has been characterised by continuous learning, adaptation and a willingness to respond to observations and recommendations aimed at improving outcomes.
He further emphasised the importance of safety in all project operations, particularly given the challenging terrain and operating conditions in Ogoniland.
He noted that safety is treated as a critical priority and that contractors are continually reminded to maintain high safety standards, stressing that lessons learnt from previous operational challenges like the collapse of the water tank in Gwara Community are being applied to strengthen safety practices and overall performance.
