Notes: Environment and its resources

Topic: topic_name_replace   |   Subject: subject_replace   |   Target age: age_replace

1. What is the environment?

The environment is everything around us — air, water, land, plants, animals and the built spaces where people live and work. It includes natural areas such as forests, rivers and lakes, and human-made places like farms, towns and roads.

2. Types of resources found in the environment

• Water (lakes, rivers, groundwater) — e.g., Lake Victoria, Tana River, groundwater wells.
• Forests and vegetation — e.g., Mau Forest complex, community woodlots.
• Wildlife — national parks and conservancies that support tourism and livelihoods.
• Soil and land — productive farms in the Rift Valley and coastal plains.
• Minerals and energy — geothermal (Olkaria), soda ash (Lake Magadi), mineral deposits.
• Air and sunlight — important for climate, crops and solar power.
• Human-made resources — buildings, roads, irrigation systems, schools and clinics.

3. Renewable vs non-renewable resources

Renewable: can be replaced naturally if used well — water (with conservation), forests (if replanted), wildlife (if habitats are protected), soil fertility (with good farming).

Non-renewable: do not return quickly once used — some minerals and fossil fuels. Example: some mineral deposits and certain fossil fuels used for energy.

4. Why these resources matter to Kenya

• Support livelihoods: farming, fishing, pastoralism and tourism employ many Kenyans.
• Provide food, water, energy and building materials.
• Contribute to the national economy: agriculture, tourism and energy (geothermal, hydro) are key sectors.
• Maintain cultural and community values: sacred forests, rivers and communal grazing lands.

5. Common threats to environment and resources (Kenyan context)

• Deforestation and illegal logging (pressure on Mau and other forests).
• Overgrazing and soil erosion in rangelands.
• Pollution of water and land from waste and chemicals.
• Overfishing and loss of fish breeding grounds in lakes and coastal waters.
• Climate change impacts — more frequent droughts, floods and shifting rainfall patterns.
• Unplanned urban expansion reducing farmland and green spaces.

6. Ways to use resources sustainably

Using resources sustainably means meeting today’s needs without stopping future generations from meeting theirs. Simple practices include:

• Planting trees and protecting forest patches (afforestation and reforestation).
• Soil conservation: terracing, cover crops, mulching, and agroforestry.
• Water conservation: rainwater harvesting, drip irrigation and fixing leaks.
• Sustainable fishing: respecting closed seasons, using appropriate gear and community controls.
• Proper waste management: reduce, reuse, recycle and safe disposal.
• Using renewable energy: solar panels and geothermal where available.
• Following laws and county plans — working with agencies (e.g., NEMA, KWS) and local groups.

7. Kenyan examples of conservation and resource use

• Community conservancies that protect wildlife and give income to local people.
• Tree-planting campaigns (national tree-planting days and school tree nurseries).
• Geothermal development in Olkaria providing cleaner energy.
• Water-supply projects and small dams for irrigation and domestic use.

8. Simple classroom & home actions for age_replace

• Grow a tree or a vegetable plant in a pot or school garden and keep a growth diary.
• Collect rainwater for watering plants and compare water saved each month.
• Organize a clean-up day around the school or neighbourhood and record the waste types found.
• Make posters that explain why a local resource (e.g., a hill, river or forest) must be protected.

9. Key terms (brief)

• Resource: something useful taken from the environment.
• Renewable: can be replaced naturally (e.g., trees, water).
• Non-renewable: limited and cannot be quickly replaced (e.g., some minerals).
• Conservation: saving and managing resources carefully.

10. Short questions to test understanding

1. Name two renewable resources found in Kenya and one non-renewable resource.
2. Give one way schools can help conserve water.
3. Explain why forests are important for communities near them.
