Lesson Content/Board Summary

Environmental Resources

Mineral Resources

Mineral resources are naturally occurring solid, liquid, or gaseous substances found within the Earth’s crust that can be extracted and used for economic purposes. They are non-renewable resources.

The following are types of mineral resources:

• Metallic Minerals: These are minerals from which metals are extracted. Examples include iron ore, gold, tin, bauxite, copper.
• Non-Metallic Minerals: These are minerals that do not contain metals. Examples include limestone, clay, sand, gravel, gypsum, salt.
• Fuel/Energy Minerals: These are minerals used as sources of energy. Examples include crude oil, natural gas, coal, uranium.

The following are uses of mineral resources:

• Industrial Use: Iron ore for steel production, bauxite for aluminium, limestone for cement.
• Energy Generation: Crude oil, natural gas, and coal for electricity and fuel.
• Construction: Sand, gravel, and clay for building materials.
• Jewellery and Currency: Gold, silver, and diamonds.

The following are problems of mineral exploitation:

• Environmental Degradation: Land destruction, deforestation, soil erosion, water pollution (from mining waste).
• Health Hazards: Exposure of miners and nearby communities to dust and harmful chemicals.
• Social Issues: Displacement of communities, conflicts over land, poor working conditions.
• Economic Issues: Price fluctuations in global markets, dependency on a single resource, resource depletion.

Land Resources

Land resources refer to the terrestrial parts of the Earth’s surface, including its physical, biotic, environmental, and socio-economic components, that can be used to meet human needs. This includes soil, topography, water bodies, and vegetation cover.

The following are types of land resources:

• Soils: The loose surface material of the Earth in which plants grow. Different soil types (e.g., sandy, clayey, loamy) support various agricultural activities.
• Plateaus: Large areas of high, flat land. They can be used for grazing, certain types of agriculture, and settlement, and may contain mineral deposits.
• Forests: Areas dominated by trees, providing timber, non-timber forest products, and ecological services.
• Water Bodies: Rivers, lakes, and oceans within or bordering land, providing water for agriculture, domestic use, and transportation.

The following are uses of land resources:

• Agriculture: For growing crops and rearing livestock.
• Settlement: For building homes, towns, and cities.
• Industrial Development: For establishing factories and industries.
• Transportation: For roads, railways, and airports.
• Recreation and Tourism: For parks, resorts, and natural attractions.
• Forestry: For timber and other forest products.

Human Resources

Human resources refer to the people who constitute the workforce of an organization, business sector, or economy. In a broader sense, it encompasses the skills, knowledge, abilities, health, and efforts of people available for the production of goods and services.

The following are types of human resources:

• Human Capital: The economic value of a worker’s experience and skills. This includes education, training, intelligence, skills, health, and other things employers value.
• Population: The total number of people living in a specific area. A larger population can mean a larger potential workforce, but also places demands on resources.
• Technology: The application of scientific knowledge for practical purposes, especially in industry. It is a product of human ingenuity and greatly enhances human productivity and resource utilization.

The following are uses of human resources:

• Labour Force: Providing the workforce necessary for all sectors of the economy (agriculture, industry, services).
• Innovation and Creativity: Driving technological advancements, scientific discoveries, and artistic creations.
• Entrepreneurship: Starting and managing businesses, creating jobs, and fostering economic growth.
• Skill Development: Through education and training, improving productivity and efficiency in various tasks.
• Governance and Administration: Managing public affairs and ensuring societal order.

Lesson Keywords

• Mineral Resources – Naturally occurring substances in the Earth’s crust used for economic purposes.
• Land Resources – Terrestrial parts of the Earth’s surface used to meet human needs, including soil and plateaus.
• Human Resources – The people, their skills, knowledge, and abilities available for production and development.
• Exploitation – The act of using or developing resources, often implying a degree of unsustainable or unfair use.
• Human Capital – The economic value of a worker’s experience and skills.

Differentiation

For pupils who grasp concepts quickly, the teacher can challenge them to research local examples of resource management initiatives. For those needing additional support, the teacher can provide simplified diagrams and allow more time for answering questions, offering one-on-one guidance.

Note for teachers using this lesson plan

Teachers should encourage pupils to relate the concepts of environmental resources to their local environment and national issues. Practical examples and visual aids are important for making the lesson engaging and understandable. Emphasize the sustainability aspect of resource management.
