Nigeria: Environment
Ecology & Environment
Ecosystems · Conservation · Wildlife · Sustainability
An overview of Nigeria’s ecological wealth, its diverse biomes—from coastal mangroves to the Sahel savanna—and the urgent environmental challenges shaping its sustainable future.
Biodiversity at
the crossroads
Nigeria’s environment is a vast mosaic of varied ecological zones. The southern coast boasts the largest mangrove ecosystem in Africa, transitioning inland into dense tropical rainforests. The expansive middle belt is dominated by the Guinea savanna, which gradually fades into the Sudan and Sahel savannas bordering the Sahara desert in the far north.
This ecological diversity supports remarkable wildlife, including the critically endangered Cross River gorilla, drill monkeys, African elephants, and an incredible array of birdlife. To protect this heritage, Nigeria has established a network of National Parks and game reserves, such as Yankari, Cross River, and Gashaka Gumti.
However, the country faces severe environmental challenges. Rapid urbanization and logging have drastically reduced primary forest cover. In the Niger Delta, decades of petroleum extraction have caused widespread oil pollution, while the northern states face aggressive desertification, combated in part by the ambitious Great Green Wall initiative.
- Biodiversity & Conservation: Protecting endangered flora and fauna.
- Deforestation: Managing logging, agriculture, and fuel-wood demand.
- Pollution Control: Addressing oil spills in the Delta and urban waste.
- Desertification: The advancing Sahara and afforestation efforts.

Environmental Challenges
Understanding the pressure on Nigeria’s ecosystems
The Niger Delta is one of the most polluted regions on earth. Decades of oil spills, pipeline vandalism, and illegal refining have severely damaged mangrove forests, poisoned fishing waters, and contaminated arable land. Initiatives like the Ogoniland Cleanup (HYPREP) aim to remediate these areas.
Northern Nigeria loses vast tracts of arable land annually to desertification, driven by climate change, overgrazing, and deforestation for firewood. This directly threatens food security and exacerbates farmer-herder conflicts. The Great Green Wall project seeks to plant a massive belt of trees to halt the Sahara’s advance.
Nigeria has one of the highest deforestation rates globally. Rapid population growth, agricultural expansion, illegal logging, and heavy reliance on biomass for cooking fuel have decimated the southern rainforests and northern woodlands, severely threatening endemic species.
Coastal cities, particularly Lagos and communities along the Gulf of Guinea, face severe threats from ocean surges and coastal erosion. Climate change-induced sea-level rise combined with sand dredging has forced the implementation of massive seawalls and land reclamation projects (like Eko Atlantic).
