Climate change isn’t a distant problem anymore; it’s happening now, especially in Nigeria. This West African country faces serious climate issues due to its size, diverse ecosystems, and population growth. Problems like rising temperatures, unpredictable rainfall, desertification, and flooding are hitting hard.
In just a century, Nigeria’s average temperature has increased by over 1.5°C, according to the Nigerian Meteorological Agency (NiMet). Northern areas like Sokoto and Maiduguri often see temperatures exceed 45°C during the hottest months. This isn’t just uncomfortable; it’s harmful to health, agriculture, and water supply.
Rainfall patterns have also changed, making them less predictable. Farmers who rely on steady rains often find themselves facing delays or sudden dry spells. In 2024, droughts struck major farming regions in the Middle Belt and South-East, followed by unexpected floods that destroyed crops. This inconsistency threatens food security, especially amid rising inflation.
One big issue is desertification in the Sahel region. Places like Yobe and Borno are losing arable land, pushing rural communities south in search of better farming conditions. This problem isn’t just environmental; it can lead to conflicts over resources, threatening national security.
Coastal areas, particularly in Lagos, Bayelsa, and Rivers states, are facing severe threats from rising sea levels. Coastal erosion is destroying farmland and submerging villages, while unregulated urban growth in Lagos is making flash floods worse. Without proper defenses, millions could be displaced in the future.
Flood impacts are also worsening. In 2022 and 2023, over 3 million people were affected by floods, according to the National Emergency Management Agency (NEMA). The 2024 floods from the Niger and Benue river basins led to significant loss of life and property damage, compounded by poor drainage systems in cities like Abuja.
Agriculture, crucial to Nigeria’s economy and employing over 35% of the workforce, is increasingly struggling. Key crops like maize and rice are yielding less due to extreme weather. Herders face water shortages and shrinking pastures, leading to clashes with farmers, particularly in the North-Central region.
On the health front, rising temperatures and humidity are increasing the spread of diseases like malaria and cholera. Flooded areas create perfect conditions for mosquitoes, while heatwaves lead to dehydration. Nigeria’s healthcare system, already under pressure, is struggling to cope with these climate-related health issues.
While Nigeria produces only about 0.3% of global greenhouse gases, it still faces significant local environmental challenges from fossil fuel use, deforestation, and gas flaring. The Niger Delta, in particular, suffers from oil spills that harm not just the environment but local communities.
The government is slowly recognizing the seriousness of climate change. In 2021, Nigeria pledged to achieve net-zero emissions by 2060 at the COP26 summit. While new laws and frameworks are in place to tackle climate issues, implementation is lagging due to corruption, funding shortages, and poor coordination among agencies.
Community groups and youth-led movements are stepping up in response to the environmental crisis. They are initiating tree-planting projects and climate education in cities like Kano and Lagos. Renewable energy startups are also emerging, helping rural communities reduce reliance on fossil fuels. However, these initiatives need additional support to expand their impact.
To adapt effectively to climate change, Nigeria needs to focus on practical strategies. Improving early warning systems, investing in resilient infrastructure, and enforcing existing environmental laws are essential. Reforestation, sustainable farming, and efficient water management should also play a key role. Importantly, climate action must integrate into national development plans to ensure steady economic growth while protecting the environment.
Climate change is more than an environmental issue; it’s affecting every facet of life in Nigeria—health, food security, and even national stability. The consequences are already clear, especially for the most vulnerable populations. While Nigeria can’t tackle global warming single-handedly, taking proactive steps is crucial. The window for meaningful action is closing, and the stakes couldn’t be higher for millions who depend on the land and climate for their survival.
