Deforestation poses the greatest threat to Nigeria's environment, with less than 4 per cent of the country's original forest cover remaining. The loss continues at a rate of 3.5 per cent annually, equivalent to about 1.5 million trees felled each day due to illegal logging. Between 1981 and 2000, Nigeria lost approximately 3.7 million hectares of forest. Bush burning and unregulated logging have long contributed to the decline, worsened by the absence of regeneration efforts. Today, over 484 plant species face extinction, while Nigeria's remaining forests still host around 4,000 plant species and unique wildlife such as the Ibadan Malimbe, Anambra Waxbill, Jos Indigo Bird, white-throated monkey, Niger Delta pygmy hippo, and Niger Delta red colobus monkey. These species are under threat from habitat loss and human activity. Criminal groups now occupy several forest reserves, undermining conservation. The National Park Service is underfunded and lacks capacity to protect biodiversity. Desert encroachment advances at over 1.6 kilometres per year, while nearly 3,000 gully erosion sites exist in the South East. Flooding plagues Lagos regularly, and rising temperatures disrupt agriculture. The Great Green Wall Project and Environmental Impact Assessment reviews have been recommended, alongside better management of Ecological Funds and stricter controls on gas flaring and power generator use.
The most urgent issue is not just deforestation, but the state's loss of control over vast forest territories to armed groups—a silent territorial takeover with ecological consequences. Where the state is absent, forests are being cleared unchecked, and the National Park Service, tasked with protecting these areas, operates without adequate funding or manpower. This collapse of environmental governance mirrors broader failures in security and public administration.
The data is stark: 3.5 per cent annual forest loss, 1.5 million trees cut daily, and 484 plant species at risk. These figures reflect decades of policy neglect, weak enforcement, and mismanagement of ecological funds. The criminal occupation of forests is not merely an environmental issue but a symptom of state fragility in rural regions. Projects like the Great Green Wall remain underfunded and poorly implemented, while gas flaring and generator dependence continue due to unresolved power deficits.
Ordinary Nigerians bear the brunt through worsening air quality, disrupted farming, and increased flooding. Rural communities lose medicinal plants and livelihoods tied to forest resources, while urban residents face extreme heat and infrastructure damage from erosion and floods. The environmental crisis is a direct threat to food security, health, and economic stability.
This pattern reflects a long-standing prioritisation of short-term political and economic gains over sustainable development. Environmental policy remains reactive, underfunded, and disconnected from local realities.
