NCERT Explained: Class X Geography, Chapter 6 - Manufacturing Industries

Introduction to the Topic

In our daily lives, we use a wide variety of goods, ranging from the sugar in our tea and the clothes we wear to the cars we drive and the computers we use for study. Have you ever wondered how these goods are produced in such large quantities? This process is known as Manufacturing. In the NCERT Class X Geography syllabus, Chapter 6 titled 'Manufacturing Industries' takes us on a journey to understand how raw materials are transformed into finished, high-value products. This chapter is crucial because it helps students understand the 'Secondary Sector' of the economy, which serves as the backbone of a nation's development.

Manufacturing is essentially the production of goods in large quantities after processing from raw materials to more valuable products. For example, paper is manufactured from wood, sugar from sugarcane, iron and steel from iron ore, and aluminum from bauxite. Some types of clothes are manufactured from yarn, which itself is a manufactured product from fiber. The economic strength of a country is often measured by the development of its manufacturing industries. This blog post will break down the complex concepts of this chapter into simple, digestible sections to help you ace your exams and understand the world around you better.

Key Concepts Explained

1. The Importance of Manufacturing

Manufacturing industries are considered the backbone of economic development for several reasons. Firstly, manufacturing industries not only help in modernizing agriculture—which forms the backbone of our economy—but also reduce the heavy dependence of people on agricultural income by providing them jobs in secondary and tertiary sectors. Secondly, industrial development is a precondition for the eradication of unemployment and poverty from our country. This was the main philosophy behind public sector industries and joint sector ventures in India. It was also aimed at bringing down regional disparities by establishing industries in tribal and backward areas.

Furthermore, the export of manufactured goods expands trade and commerce and brings in much-needed foreign exchange. Countries that transform their raw materials into a wide variety of finished goods of higher value are prosperous. India’s prosperity lies in increasing and diversifying its manufacturing industries as quickly as possible. It is also important to note that agriculture and industry are not exclusive of each other; they move hand in hand. For instance, the agro-industries in India have given a major boost to agriculture by raising its productivity.

2. Factors Affecting Industrial Location

Industries are not set up randomly. Their location is influenced by the availability of many factors. Finding all these factors at one place is almost impossible. Therefore, manufacturing activity tends to locate at the most appropriate place where all the factors of industrial production are either available or can be arranged at a lower cost. These factors include:

• Availability of Raw Materials: Industries that use heavy or bulky raw materials (like iron and steel) are located near the source of the raw materials.
• Labor: Availability of cheap and skilled labor is a major factor.
• Capital: The financial investment required to set up and run the industry.
• Power: Uninterrupted supply of electricity is essential for running machinery.
• Market: Proximity to markets ensures that finished goods reach consumers quickly and at lower transport costs.
• Government Policies: Incentives and infrastructure provided by the government play a huge role.

After an industrial activity starts, urbanization follows. Sometimes, industries are located in or near cities. Thus, industrialization and urbanization go hand in hand. Cities provide markets and also provide services such as banking, insurance, transport, labor, and financial advice to the industry. Many industries tend to come together to make use of the advantages offered by the urban centers known as agglomeration economies.

3. Classification of Industries

To understand the vast landscape of manufacturing, we classify industries into various categories based on different criteria:

• On the basis of source of raw materials:
  • Agro-based: Cotton, wool, jute, silk textile, rubber and sugar, tea, coffee, edible oil.
  • Mineral-based: Iron and steel, cement, aluminum, machine tools, petrochemicals.
• According to their main role:
  • Basic or key industries: Those which supply their products or raw materials to manufacture other goods (e.g., iron and steel, copper smelting).
  • Consumer industries: Produce goods for direct use by consumers (e.g., sugar, toothpaste, paper, sewing machines).
• On the basis of capital investment:
  • Small-scale industry: Defined with reference to the maximum investment allowed on the assets of a unit. Currently, the limit is one crore rupees.
  • Large-scale industry: Investment of more than one crore rupees.
• On the basis of ownership:
  • Public Sector: Owned and operated by government agencies (e.g., BHEL, SAIL).
  • Private Sector: Owned and operated by individuals or a group of individuals (e.g., TISCO, Bajaj Auto Ltd., Dabur Industries).
  • Joint Sector: Jointly run by the state and individuals (e.g., Oil India Ltd.).
  • Cooperative Sector: Owned and operated by the producers or suppliers of raw materials, workers, or both (e.g., the sugar industry in Maharashtra, the coir industry in Kerala).
• Based on the bulk and weight of raw material and finished goods:
  • Heavy industries: Such as iron and steel.
  • Light industries: Use light raw materials and produce light goods such as electrical industries.

4. Major Industries in India

Agro-Based Industries: Textiles

The textile industry occupies a unique position in the Indian economy because it contributes significantly to industrial production, employment generation, and foreign exchange earnings. It is the only industry in the country which is self-reliant and complete in the value chain, i.e., from raw material to the highest value-added products. The Cotton Textile Industry was traditionally concentrated in the cotton-growing belt of Maharashtra and Gujarat due to availability of raw cotton, market, transport, and moist climate. However, today, it is decentralized to provide scope for incorporating local weaving traditional skills and designs in cotton, silk, zari, embroidery, etc.

The Jute Textile Industry is mainly concentrated in West Bengal, along the banks of the Hugli River. India is the largest producer of raw jute and jute goods. The factors responsible for its location in the Hugli basin include proximity of the jute-producing areas, inexpensive water transport, and a good network of railways and roadways. However, the industry faces stiff competition in the international market from synthetic substitutes and from other competitors like Bangladesh, Brazil, Philippines, Egypt, and Thailand.

Mineral-Based Industries: Iron and Steel

The iron and steel industry is the basic industry since all the other industries—heavy, medium, and light—depend on it for their machinery and electricals. It is also considered a heavy industry because all the raw materials, as well as finished goods, are bulky and heavy, entailing heavy transportation costs. Iron ore, coking coal, and limestone are required in the ratio of approximately 4:2:1. Manganese is also required to harden the steel.

Most of the public sector undertakings market their steel through the Steel Authority of India Ltd. (SAIL). In the 1950s, China and India produced almost the same quantity of steel. Today, China is the largest producer of steel. China is also the world’s largest consumer of steel. In India, the Chhotanagpur plateau region has the maximum concentration of iron and steel industries due to the relative advantages this region has for the development of this industry, including low-cost iron ore and high-grade raw materials in proximity.

5. Industrial Pollution and Environmental Degradation

While industries contribute significantly to India’s economic growth and development, the increase in pollution of land, water, air, noise, and resulting degradation of environment that they have caused cannot be ignored. Industries are responsible for four types of pollution:

• Air Pollution: Caused by the presence of a high proportion of undesirable gases, such as sulfur dioxide and carbon monoxide. Smoke is emitted by chemical and paper factories, brick kilns, refineries, and smelting plants. It adversely affects human health, animals, plants, and the atmosphere.
• Water Pollution: Caused by organic and inorganic industrial wastes and affluents discharged into rivers. The main culprits are paper, pulp, chemical, textile, dyeing, petroleum refineries, and electroplating industries.
• Thermal Pollution: Occurs when hot water from factories and thermal plants is drained into rivers and ponds before cooling. This has a devastating effect on aquatic life.
• Noise Pollution: Not only results in irritation and anger, but it can also cause hearing impairment, increased heart rate, and blood pressure. Industrial and construction activities, machinery, and factory equipment are the primary sources.

6. Control of Environmental Degradation

Every liter of waste water discharged by our industry pollutes eight times the quantity of fresh water. How can the industrial pollution of fresh water be reduced? Some suggestions are:

• Minimizing the use of water for processing by reusing and recycling it in two or more successive stages.
• Harvesting of rainwater to meet water requirements.
• Treating hot water and effluents before releasing them into rivers and ponds. Treatment of industrial effluents can be done in three phases: primary treatment by mechanical means, secondary treatment by biological processes, and tertiary treatment by biological, chemical, and physical processes.
• Particulate matter in the air can be reduced by fitting smoke stacks to factories with electrostatic precipitators, fabric filters, scrubbers, and inertial separators.
• Noise can be controlled by silencers on machinery and equipment, and by redesigning machinery to be more efficient and less noisy.
