Agriculture as a Source of Raw Materials for Industries Basic 4 Agricultural Science Lesson Note

What Are Raw Materials?

Raw materials are natural products from farms that factories use to make other useful things we need.

What Are Industries?

Industries are factories or companies that use raw materials to make finished products that people buy and use.

How Agriculture Provides Raw Materials

1. Textile Industry (Making Clothes)

Cotton

• Raw material: Cotton plants
• What industries make: Clothes, bedsheets, towels, bags
• Process: Cotton → Thread → Fabric → Clothes

Silk

• Raw material: Silkworms (raised on farms)
• What industries make: Silk clothes, scarves, ties

2. Food Processing Industry

From Crops:

• Maize → Cornflakes, popcorn, corn oil
• Cassava → Garri, starch, flour, alcohol
• Rice → Rice flour, rice cakes
• Sugarcane → Sugar, sweets, soft drinks
• Palm fruits → Palm oil, soap, margarine

From Animals:

• Milk → Cheese, butter, yogurt, ice cream
• Meat → Sausages, canned meat, dried meat

3. Paper and Wood Industry

Trees (Forestry)

• Raw material: Wood from trees
• What industries make: Paper, books, furniture, houses
• Types: Newspapers, exercise books, cardboard boxes

4. Leather Industry

Animal Skins

• Raw material: Cow, goat, and sheep skins
• What industries make: Shoes, bags, belts, jackets
• Process: Animal skin → Leather → Leather products

Rubber Industry

Rubber Trees

• Raw material: Rubber sap from rubber trees
• What industries make: Car tires, shoes, gloves, balloons

6. Cosmetics and Soap Industry

Plant Oils:

• Palm oil → Soap, shampoo, body cream
• Coconut oil → Hair oil, skin cream
• Shea butter → Body lotion, lip balm

7. Pharmaceutical Industry (Medicine)

Medicinal Plants:

• Herbs and plants → Traditional and modern medicines
• Examples: Neem, bitter leaf, ginger for health products

Examples in Nigeria

Major Agricultural Raw Materials:

• Cotton → Textile mills in Kaduna, Kano
• Palm oil → Soap factories across Nigeria
• Cocoa → Chocolate factories
• Rubber → Tire manufacturing companies
• Wood → Furniture factories, paper mills

Benefits of Agriculture to Industries

1. Constant Supply

• Farms provide steady raw materials
• Industries can produce throughout the year
• Helps factories plan production

2. Job Creation

• Farm workers grow raw materials
• Factory workers process them
• Many people get employed

3. Economic Growth

• Raw materials are cheaper than imports
• Nigeria saves money by using local materials
• Industries grow and expand

4. Value Addition

• Simple farm products become valuable goods
• Raw cotton becomes expensive clothes
• Increases the worth of agricultural products
