Washing and Hushing
Nigeria needs growth. With inflation biting hard, unemployment remaining stubbornly high, infrastructure gaps widening, and millions slipping deeper into poverty, economic expansion is no longer a political slogan; it is a national necessity. From Lagos to Kano, from Port Harcourt to Abuja, the race for roads, factories, housing estates, industrial parks, and transport infrastructure reflects a country desperate to modernize. But beneath the optimism lies a troubling contradiction: almost every major sign of economic growth in Nigeria still comes with a rise in greenhouse gas emissions.
Nigerians are often told that things are getting better, that GDP is rising, that the numbers are moving in the right direction. In 2024, Nigeria’s economy grew by approximately 3.4 percent, an improvement on prior years. In the second quarter of 2024 alone, GDP expanded by 3.19 percent year-on-year, driven by the services and industry sectors. The government and its cheerleaders call this progress. What they rarely mention is what this progress costs the planet, people and local communities.
In 2024, Nigeria’s fossil CO₂ emissions climbed to approximately 131.9 million tonnes — up from 125.9 million tonnes in 2023, a rise of 4.8 percent in a single year, according to data from Worldometer. To put that plainly: the year Nigeria celebrated improved economic output, it also released six million additional tonnes of carbon dioxide into the air. The compound annual growth rate of Nigeria’s greenhouse gas emissions, at 1.4 percent, has been running at more than double the country’s compound annual GDP growth rate of 0.62 percent over the past decade, according to data from the World Resources Institute. Nigeria is not just growing; it is growing dirty, and the gap between economic ambition and environmental reality is widening with every new policy announcement that goes unimplemented.
The relationship is becoming impossible to ignore; Nigeria’s GDP growth, rather than becoming cleaner and more efficient, continues to move almost hand-in-hand with carbon emissions. This is the carbon cost of growth, and Nigeria is paying heavily for it. Nigeria may contribute a relatively small share of global emissions compared to industrial giants like China or the United States, but that does not erase the seriousness of the challenge. Recent estimates place Nigeria’s greenhouse gas emissions at over 350 million tons of CO₂ equivalent in 2024, continuing an upward trend. The uncomfortable reality is that Nigeria is urbanizing, industrializing, and expanding using one of the dirtiest development pathways possible.
Transport: The silent engine of Nigeria’s carbon crisis
Few sectors capture Nigeria’s carbon dilemma more clearly than transportation. Nigeria’s transport system is overwhelmingly dependent on fossil fuels. Petrol-powered cars dominate urban mobility while diesel trucks carry most commercial goods across the country. Public transportation remains weak, rail infrastructure is underdeveloped, and non-motorized mobility receives little policy attention.The result is a transport economy built almost entirely around combustion engines. Every day, Lagos alone loses enormous productive hours to traffic congestion. Millions of vehicles idle for hours, burning fuel while barely moving. In Abuja, Port Harcourt and Kano, rapid urban expansion has outpaced transport planning, forcing dependence on private vehicles and informal transport systems and the climate consequences are severe.
The International Energy Agency (IEA) notes that transport energy use in most countries remains dominated by oil consumption, especially through passenger vehicles and freight movement. In Nigeria, this dependence is intensified by poor fuel quality, aging vehicle fleets, and weak emission enforcement. Imported second-hand vehicles, many with outdated emission standards, continue flooding Nigerian roads. Diesel generators powering logistics facilities, transport hubs, and warehouses further deepen emissions intensity. Ironically, economic growth itself worsens the problem. As incomes rise modestly, more Nigerians aspire to own cars. As trade expands, more trucks move goods nationwide. As cities spread outward without effective urban planning, commuting distances become longer and more carbon-intensive. Nigeria is therefore trapped in a vicious cycle: growth increases mobility demand, and mobility demand increases fossil fuel consumption. The country’s railway modernization efforts and emerging electric mobility conversations remain too slow to fundamentally alter the trajectory. Without aggressive investment in mass transit, clean mobility and urban redesign, transport emissions will continue rising alongside GDP.
Industrial growth without industrial transition
Nigeria’s industrial ambitions are understandable. No country develops without manufacturing. The desire to strengthen cement production, steel, petrochemicals, fertilizer, manufacturing, and processing industries reflects a legitimate push for economic transformation. But industrialization in Nigeria remains overwhelmingly fossil-fuel dependent. Factories rely heavily on diesel because of unreliable electricity supply. Many industrial clusters operate almost like self-powered energy islands, running generators for long hours daily. This creates a hidden but massive carbon burden. Energy inefficiency also remains widespread. Outdated machinery, poor production technologies, and limited energy management systems mean industries consume more energy than necessary for each unit of output.
The IEA emphasizes that sectors such as cement, chemicals and steel remain among the most energy-intensive industrial activities globally because they require high-temperature heat processes still largely powered by fossil fuels. Nigeria’s cement boom perfectly illustrates this contradiction. Cement production has become central to Nigeria’s economic narrative because construction demand is soaring. Roads, bridges, housing projects, and urban expansion all depend heavily on cement. Yet cement manufacturing is one of the world’s largest industrial sources of carbon emissions due to both fuel combustion and chemical production processes.
So, while new infrastructure boosts GDP figures, it simultaneously locks in higher emissions. The same applies to petrochemicals, plastics and fertilizer industries. Global climate experts increasingly warn that petrochemical expansion could become one of the fastest-growing sources of industrial emissions worldwide.
Nigeria’s industrial policy still prioritizes output growth more than decarbonization. Clean industrial transition remains largely absent from mainstream economic planning and this is where the real danger lies. The country risks building an economy that may become globally uncompetitive in the future as international markets tighten carbon regulations. Europe is already moving toward carbon border adjustment mechanisms that could penalize carbon-intensive imports. Global investors are increasingly screening projects through environmental standards. An industrial strategy that ignores carbon efficiency is therefore not only environmentally risky; it is also economically risky.
The dangerous illusion
One of the most common arguments in Nigeria’s climate debate is that emissions reduction should not be prioritized because the country contributes little to global emissions. This argument sounds politically attractive, but it ignores two critical realities. First, climate change is already damaging Nigeria’s economy. Floods, desertification, erosion, heat stress, and agricultural disruptions are imposing enormous economic costs. Productivity losses, displacement, and infrastructure destruction are becoming increasingly severe.
Second, the future global economy will reward low-carbon competitiveness. Countries that continue expanding through dirty energy systems risk becoming stranded in outdated economic models. Investors, development finance institutions, and export markets are increasingly shifting toward cleaner production systems. Nigeria, therefore, faces a strategic choice: either modernize now through cleaner growth pathways or risk expensive transitions later under global economic pressure.
The dangerous assumption that development must automatically mean pollution is no longer defensible. Several economies are gradually decoupling emissions from growth through renewable energy investments, cleaner public transportation, industrial efficiency, and green building standards. Discussions around carbon pricing and emissions regulation are also becoming more mainstream globally. Nigeria cannot afford to remain stuck in twentieth-century growth models while the rest of the world moves toward low-carbon economies.
Trends and Threads
How Nigeria Grows Food but Still Goes Hungry
Nigeria is blessed with fertile land, vast rivers, a huge farming population, and one of the largest agricultural economies in Africa. Yet, in a painful contradiction, millions of Nigerians are struggling to afford basic meals. In many homes today, food is no longer about nutrition or choice; it is about survival. Rice has become a luxury for some families, tomatoes disappear from kitchens during price spikes, and farmers increasingly fear the weather more than pests. The question now confronting the country is both urgent and uncomfortable: can Nigeria truly feed itself sustainably in an era of climate change, which has exacerbated insecurity and economic instability?
The warning signs are no longer distant forecasts from scientists. They are already visible in flooded farmlands across Kogi and Benue, dried-up soils in the North, rising food prices in city markets, and worsening hunger in rural communities. What used to be occasional climate shocks have become a permanent feature of Nigeria’s food system. According to the Food and Agriculture Organization of the United Nations (FAO), about 33.1 million Nigerians are projected to face food insecurity during the 2025 lean season. The drivers include inflation, conflict, floods, and climate-related disruptions. This is no longer simply an agricultural problem. It is an economic crisis, a governance crisis, and increasingly, a national security crisis.
When the rain comes and goes without pattern
For decades, Nigerian farmers relied on seasonal patterns they understood. The rains came at predictable periods, planting seasons followed familiar rhythms, and harvests, though imperfect, remained somewhat reliable. That certainty has collapsed. Today, climate change is disrupting nearly every stage of food production. Floods wash away hectares of farmland in one region while drought destroys crops in another. Heatwaves reduce yields. Pests spread faster. Livestock struggle with water shortages. Fishing communities are also battling changing water conditions. The most worrying part is that Nigeria’s agriculture is still overwhelmingly rain-fed. This means millions of farmers depend almost entirely on weather conditions they can no longer predict.
In 2024 alone, flooding reportedly affected over 9 million people and submerged around 1.6 million hectares of farmland, according to FAO assessments. Production losses for major staples like maize, rice, and sorghum were estimated at over one million tonnes. This explains why food prices now react almost instantly to climate disasters. A flood in one farming belt quickly translates into higher prices in Lagos, Abuja, and Port Harcourt markets. Climate change is no longer an environmental issue sitting on the margins of policy debates. It is already sitting at Nigerian dining tables.
Hunger in the midst of abundance
Nigeria has over 70 million hectares of agricultural land, yet food imports continue to rise while local production struggles to meet demand. The country grows cassava, yams, maize, rice, millet, and sorghum on a massive scale, but post-harvest losses, poor storage systems, and weak infrastructure continue to cripple food availability. This is one of the deepest ironies of Nigeria’s food crisis: the country produces food, but cannot efficiently preserve, transport, or distribute it. Large quantities of tomatoes rot before reaching markets because of poor cold-chain systems. Rural farmers lose harvests due to bad roads and a lack of storage facilities. Fertilizer prices remain unstable. Access to credit is weak. Irrigation coverage is still painfully limited despite years of policy promises. Climate change is now amplifying these structural failures. When floods destroy roads, food transportation becomes more expensive. When extreme heat reduces harvests, scarcity drives inflation. When insecurity forces farmers away from their land, production declines further. The result is a vicious cycle where climate vulnerability and economic hardship feed each other.
The real cost of food inflation
Food inflation in Nigeria has become one of the clearest indicators of national distress. The average Nigerian household now spends a huge portion of its income simply trying to eat. FAO and National Bureau of Statistics (NBS) data show food inflation reached alarming levels in 2024, with staple foods such as beans and local rice recording massive year-on-year increases. But beyond the statistics lies a deeper reality. Rising food prices are changing social behavior across the country. Families are reducing meal portions. Nutrition quality is declining. Protein consumption is dropping among low-income households. Many people now skip meals entirely. For children, this carries long-term consequences. Malnutrition weakens learning outcomes, health development and future productivity. A country battling food insecurity today may ultimately pay for it through a weakened workforce tomorrow.
Climate change affects every country, but not every country is equally prepared. Nigeria’s vulnerability comes from a dangerous combination of dependence on rain-fed farming, weak infrastructure, poverty, and governance failures. The poorest farmers often have the least access to irrigation, insurance, climate information, or financial support. Research on climate-induced food insecurity in Nigeria shows that floods and droughts are increasingly undermining agricultural productivity, especially in vulnerable northern regions.
Many farmers are adapting on their own through local innovations, changing planting dates or diversifying crops. But adaptation at the individual level cannot replace coordinated national action. The country still lacks sufficient investment in climate-smart agriculture. Irrigation expansion remains slow. Agricultural extension services are weak. Early warning systems are inadequate in many rural communities. Nigeria often responds to food crises after damage has already occurred rather than preparing before disasters strike.
Food security and the SDGs
Nigeria’s food crisis is directly linked to the failure to achieve several key United Nations Sustainable Development Goals (SDGs). The most obvious is SDG 2 – Zero Hunger: But Nigeria is clearly struggling to meet that target as millions continue to face acute food insecurity, rising malnutrition and worsening food inflation.
The crisis also threatens SDG 1 – No Poverty. This is because food inflation pushes vulnerable households deeper into economic hardship. When families spend most of their income on food, poverty becomes harder to escape. SDG 3 – Good Health and Well-being is also under pressure: Poor nutrition is rising quietly across many households as families reduce protein intake and substitute nutritious foods with cheaper alternatives. Climate change itself links directly to SDG 13 – Climate Action: Floods, droughts, desertification, and extreme heat are already damaging agricultural productivity across Nigeria. Without serious climate adaptation, food insecurity will worsen significantly. Perhaps most importantly, Nigeria’s food crisis also connects strongly to SDG 16 — Peace, Justice and Strong Institutions. Insecurity in farming regions, weak policy implementation, and poor governance continue undermining agricultural productivity nationwide. This is why food security must stop being treated as an isolated agricultural discussion. It is now a core governance issue. A climate issue. An economic issue. And increasingly, a national security issue. Because no country can truly develop sustainably when millions of its citizens are uncertain about their next meal.
The crisis is beyond a temporary response
Nigeria’s food crisis is not simply about farming. It is about system failure, and unless the country’s major institutions begin to respond deliberately and strategically, climate change will continue exposing those weaknesses with devastating consequences. One of Nigeria’s biggest problems is that food insecurity is still treated as an emergency issue instead of a long-term structural issue. Every year, after major floods destroy farms, government officials visit affected communities, announce relief packages, and promise interventions. But when the floodwaters disappear, the structural problems remain untouched. This cycle is unsustainable.
The Federal Ministry of Agriculture and Food Security must move beyond seasonal interventions and aggressively pursue climate-resilient agriculture policies. Nigeria still irrigates only a small fraction of its cultivated land despite increasing drought risks. The country remains dangerously dependent on rainfall at a time when climate patterns are becoming more unpredictable. The government should prioritise large-scale irrigation investments in states like Kebbi, Kano, Jigawa, Niger, and Sokoto, where rice, wheat, and vegetable production can expand significantly under stable water systems. Nigeria also urgently needs a functioning national grain reserve system. It is unacceptable that food prices spiral uncontrollably after every climate shock because reserves are weak or poorly managed. Countries serious about food security do not wait for shortages before acting.
The Federal Ministry of Environment must equally stop treating climate policy as separate from agricultural policy. Flood management, desertification control and water conservation should now be directly tied to food security planning. Most importantly, Nigeria’s annual budgets must start reflecting the scale of the crisis. Agriculture continues to receive far less funding than sectors with far less direct impact on human survival.
Many state governments speak proudly about agriculture during political campaigns but fail to build real food systems after elections. Benue calls itself the “Food Basket of the Nation,” yet farmers there continue facing insecurity, poor rural roads and post-harvest losses. In states like Kogi and Niger, yearly flooding repeatedly destroys farmland with little long-term mitigation strategy. In the North-East, conflict continues disrupting farming activities while millions remain dependent on humanitarian support.
Governors must stop seeing agriculture as symbolic politics and begin treating it as economic infrastructure. States should invest directly in: climate-resilient rural roads, modern storage facilities, agro-processing centres, local irrigation systems, farmer insurance schemes, and extension services that teach climate-smart farming techniques. Many farmers still rely on outdated information despite worsening climate conditions. Extension systems across several states are either weak, underfunded, or nearly absent. Without local implementation, federal agricultural policies will continue failing on the ground.
