Climate Change to Cost Nigeria $460bn by 2050 – Expert
Prof. Chuwumerije Okereke, Director, Centre for Climate Change and Development at the Alex Ekwueme Federal University, Ebonyi State, says climate change will cost Nigeria $460 billion by 2050, if action is not taken to mitigate its effects.
Okereke made the disclosure in an interview with the reporters 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 that 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 achieved 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. (NAN)

BTG set to Tackle Environmental Degradation in Kaduna
In a bid to tackle environmental degradation impacting negatively on communities in Kaduna state, Bridge That Gap Hope for Africa Initiative (BTG), in partnership with the Network of Civil Society in Environment (NCSE) has launched a transformative project aimed at empowering women and advancing sustainable climate governance.
Executive Director Bridge that Gap Hope for Africa Initiative (BTG), Gloria Kasang Bulus, who dropped the hint in Kaduna during the week, regretted that environmental disasters and shocks have deepened poverty and eco-anxiety among women who remain grossly under-represented in decision-making.
The project is tagged “Women Empowerment and Climate Resilience Initiative”While revealing that the project would focus on three Local Government Areas of Zaria, Chikun, and Zango Kataf, Ms Bulus stated that reports from these three local councils were troubling because “they show high levels of environmental degradation, food insecurity and limited female representation in governance structures”
“Kaduna state faces a troubling mix of environmental, social, and economic challenges.
From extensive deforestation and desertification to resource shortages and ecosystem breakdowns, the impacts of climate change have become severe. A report by Global Forest Watch shows that in 2023 alone, the state lost over 5,400 hectares of natural forest, leading to 1.94 million metric tons of CO₂ emissions.These environmental shocks have worsened poverty and eco-anxiety, especially among women who are disproportionately affected but remain underrepresented in decision-making. Although women play important roles in agriculture, small businesses, and household sustainability, they often lack access to platforms and resources that could help them influence climate policies and local development strategies.
The project focuses on LGAs with some of the worst environmental records:
- Zaria LGA suffers from massive vegetation loss due to fuelwood consumption, which accounts for nearly 40% of its deforestation. According to satellite data from 1973 to 2014, over 80% of vegetation in the area has been degraded, highlighting the urgent need for clean energy alternatives and community-led environmental restoration (Global Forest Watch).
- Zango Kataf LGA faces challenges from erratic rainfall, rising temperatures, and soil degradation. Women and internally displaced persons are especially vulnerable to water shortages and land conflicts, worsened by deforestation caused by agricultural practices.
- Chikun LGA, especially communities like Kakau Daji, is experiencing rapid environmental decline due to firewood collection and industrial pollution from nearby petrochemical plants. The ecosystem has suffered from biodiversity loss, soil erosion, and toxic emissions.
With women at the forefront
focusing on gender inclusion and environmental sustainability, the project aims to strengthen women-led coalitions by improving their policy advocacy skills, providing them with energy-efficient cookstoves, and developing a climate action plan that considers gender and Persons with Disabilities (PWD) in line with the Kaduna State Climate Change Policy.
“Women are central to community life. They manage natural resources, care for households, and make significant contributions to the economy.
“However, they still face marginalization in important decisions about the environment and development. By providing women with advocacy tools and encouraging cooperation among policymakers, civil society, and the private sector, the project aims to change this situation”, Bulus volunteered.
According to her, the goals of the initiative is built around four core objectives:
*Enhancing Policy Advocacy Capacity – Training women’s groups to participate in governance structures and advocate for inclusive climate strategies.
*Developing Inclusive Climate Action Plans – Ensuring that gender and PWD perspectives are prioritized in environmental policies.
*Promoting Climate Adaptation – Implementing grassroots solutions like reforestation, clean energy use, and climate-smart agriculture.
*Strengthening Multi-Stakeholder Collaboration – Fostering collaboration among women’s coalitions, government agencies, and environmental stakeholders.
She assured that her organization remains determined to build sustainable communities by removing barriers to basic rights of vulnerable populations.
The organization has also concluded preparations to plant 15,000 trees in the state. To date, over three thousand (3000) economic and forest trees have been planted in Chikun LGA and its environs.
She further disclosed:
“Journalists in Kaduna will also receive training to enhance their skills in effective writing and reporting on climate change-related issues.
“The Partnership for Agile Governance and Climate Engagement (PACE) Project supports coalitions that influence governments to address climate and governance issues affecting the poorest and most vulnerable communities. It aims to boost state government revenue from internal sources, integrate climate actions into state policy, planning, and budgets, and enhance election delivery and credibility.
The program, she stated, is being carried out in Kaduna, Kano, and Jigawa in northwestern Nigeria, with focused strategic engagement at both federal and regional levels.

First Lady Seeks Lasting Solution to Eradicate Environmental Pollution
The First Lady, Sen. Oluremi Tinubu has called for a lasting solution to eradicate environmental pollution caused by plastic wastes.
In her message to mark the year 2025 World Environment Day, with the theme ‘Ending Plastic Pollution’, in Abuja on Thursday, the first lady also advised people to curtail the way they consume food and drinks packaged in plastics.
“I join millions of Nigerians and the world in calling for urgent and united action to safeguard our environment.
Plastic pollution has become one of the most pressing environmental challenges of our time, affecting our health, our environment, and our future.“In Nigeria, we must rise to this challenge by changing how we consume packaged food items and how we dispose of plastic containers and bags.
“I particularly want to speak to our youths, the leaders of tomorrow, be it in schools or within our neighborhoods, each of you has a role to play in creating a cleaner, healthier and greener Nigeria,” she said.
Mrs Tinubu had recently promised to introduce environmental solutions clubs to schools through her NGO, Renewed Hope Initiative (RHI).
“I want to use this opportunity to introduce our students to two programmes that the RHI will be launching soon.
“First is the Environment Club for Secondary School Students and the Environment Society for Students in Tertiary institutions nationwide to help us clean up our environment and grow more trees.
“Second is the “Flow with Confidence” for our girls in rural communities.
“This programme is to provide one year’s supply of disposable sanitary pads to our adolescent girls to support them to remain in school during their menstrual cycle,” She said.
NAN further reports that some of the functions of RHI environmental clubs in schools would include raising environmental awareness; fostering social and life skills; empowering students to take action and promoting sustainable behaviours.
The clubs can also enhance critical thinking and creativity, encourage healthy lifestyles, and strengthen communities.
The club would encourage students to participate in various environmental projects, like tree planting, recycling, and garden projects, gaining practical experience and deeper understanding.(NAN))

Billboard accident: Abia Govt. to Offset Victims’ Hospital Bills – ABSAA Official
Abia Government says it will offset the hospital bills of the Aba Billboard accident victims.
Mrs Victoria Onwubiko, Managing Director, Abia State Signage and Advertising Agency (ABSAA) made this known on Thursday in Aba at the Salad Market entrance, the site of the accident.
A big billboard fell on some passengers in five tricycles in Aba on Wednesday, following a boisterous wind, killing one person and injuring seven others.
Onwubiko said the governor had given the necessary approval for procedures regarding the victims’ treatment without hindrances.
“So, we are glad there are not going to be any more deaths; from what we have seen, the victims in the hospital are recovering and doing well.
“We understand that about eight persons were involved in the accident; five are at the Abia University Teaching Hospital, two have been discharged and one is died,” she said.
Onwubiko added that the governor had sent his Chief of Staff to the hospital for the proper management of the victims at ABSUTH, Aba.
According to her, there is no hoping that any one of them will go to the court as the state government is doing everything to take care of them.
He said ABSAA would ensure such accidents did not reoccur noting that henceforth the agency would inspect every advertising site in the state.
“We are going to ask the owners of sites like this to give us the technical drawings with which they built their sites.
“If we don’t see them, the bill board will come down for them to redo it to ensure safety,” she said.
The ABSAA MD said every site, whether high or low, which is not sound, will go down.
Mr Chinedu Nwibo, an eye-witness and a vulcaniser for tricycle operators, said there were seven persons at the entrance of the Salad Market on that Wednesday when the accident occurred.
“We were inside a little makeshift shop I had set up for my work when the rain started on Wednesday.
“The wind was very boisterous and some of the tricycle operators went into their tricycles to stay for the rain to stop.
“No sooner had they ran into their tricycles than a big iron pipe used to hoist a billboard fell on them.
“One Destiny Uguru, 27, from Izzi in Ebonyi state died from the accident while seven persons sustained injury,” he said.
Nwibo called on the government to come to the aid of the victims especially by replacing their tricycles.
“The man that lost his life has an expectant wife and two children,” he said. (NAN)
