Quick Summary
- Environmental resources are natural materials that humans use for survival and development
- They include renewable resources (forests, water) and non-renewable resources (crude oil, minerals)
- Nigeria has abundant environmental resources including petroleum, natural gas, forests, and agricultural land
- Proper management prevents depletion and environmental degradation
- Sustainable use ensures resources are available for future generations
What Are Environmental Resources?
Environmental resources are gifts of nature that we find around us. They exist in our land, water, air, and soil. These resources help us survive and improve our quality of life. When you drink water from a borehole, use firewood for cooking, or see a car using petrol, you are witnessing the use of environmental resources.
Nigeria is blessed with many environmental resources. From the crude oil in the Niger Delta to the cocoa farms in Oyo State, from the tin mines in Jos to the fishing grounds in Lagos Lagoon, our country has diverse natural wealth that supports millions of people.
Types of Environmental Resources
Environmental resources can be grouped into two main categories based on how long they last and whether they can be replaced.
1. Renewable Resources
These are resources that can be replaced naturally over time. They don’t run out if we use them wisely. Examples include:
- Forests: Trees in Cross River, Ogun, and Ondo states can regrow if we plant new ones after cutting
- Water: Rivers like River Niger and River Benue are refilled by rain each year
- Solar energy: Sunlight is available every day and never finishes
- Wind energy: Wind keeps blowing and can generate electricity
- Soil: Soil fertility can be restored through proper farming methods
- Wildlife: Animals reproduce and increase their population naturally
2. Non-Renewable Resources
These resources take millions of years to form. Once we use them up, they cannot be replaced in our lifetime. Examples include:
- Crude oil: Nigeria’s main export from states like Rivers, Delta, and Bayelsa
- Natural gas: Found alongside crude oil in the Niger Delta
- Coal: Found in Enugu State, used for generating electricity
- Minerals: Tin in Plateau, gold in Zamfara, limestone in Edo
- Granite: Used for construction, found in many Nigerian states
Classification by Origin
We can also group environmental resources based on whether they come from living things or non-living things.
Organic (Biotic) Resources
These come from living organisms or were once alive. They include:
- Forests and trees (timber, firewood, medicinal plants)
- Wildlife (bushmeat, animal products like leather)
- Marine resources (fish from Atlantic Ocean, shrimps, crabs)
- Agricultural products (yam, cassava, rice, cocoa, palm oil)
- Livestock (cattle from Sokoto, goats, chickens)
Inorganic (Abiotic) Resources
These come from non-living things. They include:
- Water (rivers, lakes, groundwater)
- Air and wind
- Minerals (iron ore, gold, columbite)
- Fossil fuels (petroleum, coal, natural gas)
- Rocks and soil
- Sunlight

Importance of Environmental Resources
Environmental resources play vital roles in our daily lives and national development.
Economic Benefits
- Foreign exchange: Nigeria earns billions of naira from exporting crude oil, cocoa, and timber
- Employment: Millions work in farming, fishing, mining, and oil industries
- Raw materials: Industries depend on resources like cotton for textiles, timber for furniture
- Revenue generation: Government collects taxes from resource extraction companies
Social Benefits
- Food security: Agricultural resources provide food for over 200 million Nigerians
- Energy supply: Oil, gas, and coal generate electricity for homes and businesses
- Shelter: Building materials like sand, granite, and timber construct houses
- Healthcare: Medicinal plants from forests treat various diseases
Environmental Benefits
- Climate regulation: Forests absorb carbon dioxide and produce oxygen
- Water cycle maintenance: Forests and wetlands regulate rainfall patterns
- Biodiversity conservation: Natural habitats support various plant and animal species
- Soil protection: Vegetation prevents erosion in areas like Anambra and Enugu
Problems Facing Environmental Resources in Nigeria
1. Overexploitation
Using resources faster than they can be replaced. Illegal logging in Cross River destroys forests. Overfishing in Nigerian waters reduces fish populations.
2. Poor Management
Lack of proper planning leads to waste. Gas flaring in the Niger Delta wastes natural gas that could generate electricity. Abandoned tin mines in Jos create environmental hazards.
3. Pollution
Oil spillage in Rivers and Bayelsa states contaminates water and farmland. Industrial waste from factories in Lagos pollutes lagoons. Plastic waste blocks drainage channels across Nigerian cities.
4. Climate Change
Rising temperatures affect agriculture. Desertification in northern Nigeria reduces farming land. Flooding in coastal areas damages infrastructure and displaces communities.
5. Lack of Technology
Outdated methods waste resources. Farmers still use primitive tools that reduce productivity. Small-scale miners use harmful techniques that damage the environment.
Conservation of Environmental Resources
Conservation means using resources wisely so they remain available for future generations.
Government Efforts
- Creating national parks like Yankari (Bauchi) and Okomu (Edo) to protect wildlife
- Establishing agencies like NESREA to enforce environmental laws
- Banning open grazing to prevent conflicts and land degradation
- Promoting renewable energy through solar power projects
- Regulating mining activities to reduce environmental damage
Individual Actions
- Planting trees around homes and schools
- Reducing plastic use and recycling waste
- Using energy-saving bulbs and solar panels
- Practicing sustainable farming methods like crop rotation
- Reporting illegal mining and logging to authorities
- Conserving water by fixing leaking taps
Community Initiatives
- Forming local vigilante groups to prevent illegal logging
- Organizing cleanup exercises in markets and streets
- Creating community gardens for food security
- Educating people about proper waste disposal
- Supporting eco-tourism in areas like Ikogosi Warm Springs
Sustainable Use of Resources
Sustainability means meeting today’s needs without destroying tomorrow’s resources. In Nigeria, this approach is becoming important.
In agriculture: Farmers in Benue rotate crops to maintain soil fertility instead of using only fertilizers. They plant yam one season, then maize the next season.
In fishing: Fishing communities along Lagos coast are learning to avoid catching young fish. This allows fish populations to grow.
In energy: Some Nigerian homes now use solar panels instead of relying only on generators that burn petrol. This saves money and reduces pollution.
In mining: Proper mining techniques can extract minerals without destroying entire landscapes. Rehabilitation programs help restore mined areas.
Common Exam Mistakes
WAEC examiners report these frequent errors:
- Confusing renewable and non-renewable: Students wrongly classify crude oil as renewable because it’s found underground. Remember, if it takes millions of years to form, it’s non-renewable
- Listing without explaining: When asked to “explain the importance of environmental resources,” students just write “for agriculture, for industry” without saying how they’re important
- Ignoring Nigerian examples: Using only foreign examples instead of Nigerian resources like Niger Delta oil or Jos tin mines
- Mixing up conservation methods: Confusing government actions (creating laws) with individual actions (recycling plastic)
- Poor expression: Writing “They are using it for doing many things” instead of “They provide raw materials for industries”

Essay Questions
1. Explain five importance of environmental resources to Nigeria’s development. (10 marks)
Examiner’s tip: Use the word “explain,” so don’t just list. Say what each importance means. Example: “Environmental resources provide employment – millions of Nigerians work in farming, mining, and oil industries, earning income to support their families.”
2. State four problems facing environmental resources in Nigeria and suggest three solutions. (10 marks)
Examiner’s tip: “State” means list briefly, but “suggest” means give practical solutions. Don’t just write “government should help” – say exactly what government should do, like “establish stricter penalties for illegal mining.”
3. Distinguish between renewable and non-renewable resources, giving two examples of each from Nigeria. (8 marks)
Examiner’s tip: “Distinguish” means show clear differences. Start by defining each type, then explain what makes them different, then give Nigerian examples with their locations.
