Manufacturing Industries — Importance, Classification & Agro-based Industries

NCERT Contemporary India-II | Chapter 6: Manufacturing Industries

What Is Manufacturing?

Workers employed in secondary activities^? transform primary materials into finished products. Those working in steel plants, automobile factories, textile mills, and bakeries all belong to this sector. The economic strength of any country can be gauged by the development of its manufacturing industries.

Importance of Manufacturing

The manufacturing sector is often described as the backbone of economic development. There are several reasons why this sector holds such critical importance:

Classification of Industries

Industries can be classified using various criteria. Understanding these classifications helps us appreciate the diversity and complexity of India's industrial landscape.

By Source of Raw Materials

By Main Role

By Ownership

By Bulk and Weight

Agro-based Industries

Industries that derive their raw materials from agricultural products are called agro-based industries. These include cotton, jute, silk, woollen textiles, sugar, and edible oil industries.

Textile Industry

The textile industry^? occupies a unique position in the Indian economy. It contributes significantly to industrial production, employment generation, and foreign exchange earnings. It is the only industry in the country that is fully self-reliant and complete in the entire value chain — from raw material to the highest value-added products.

Cotton Textiles

In ancient India, cotton textiles were produced using hand spinning and handloom weaving. Power looms appeared after the 18th century. Traditional industries suffered during the colonial period as they could not compete with mill-made cloth from England.

Initially, the cotton textile industry was concentrated in the cotton-growing belt of Maharashtra and Gujarat, owing to the availability of raw cotton, market access, port facilities, labour, and moist climate. This industry supports farmers, cotton boll pluckers, and workers engaged in ginning, spinning, weaving, dyeing, designing, packaging, tailoring, and sewing.

While spinning remains centralised in Maharashtra, Gujarat, and Tamil Nadu, weaving is highly decentralised, allowing traditional skills in cotton, silk, zari, and embroidery to flourish. India has world-class spinning capacity, but weaving quality lags behind because powerlooms and handlooms cannot fully utilise the high-quality yarn produced domestically.

Jute Textiles

India is the largest producer of raw jute^? and jute goods, ranking second in the world as an exporter after Bangladesh. Most jute mills are located in West Bengal, concentrated along the banks of the Hugli river in a narrow belt.

Several factors explain why jute mills are concentrated along the Hugli basin: proximity to jute-growing areas, inexpensive water transport, good railway and road network, abundant water for processing, cheap labour from West Bengal and neighbouring states, and Kolkata's banking, insurance, and port facilities for exporting jute goods.

Sugar Industry

India is the second-largest sugar producer in the world and holds first place in producing gur^? and khandsari. The raw material (sugarcane) is bulky, and its sucrose content decreases during transportation.

Sugar mills are spread across Uttar Pradesh, Bihar, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Gujarat, Punjab, Haryana, and Madhya Pradesh. About 60 per cent of mills are in Uttar Pradesh and Bihar. Since the industry is seasonal in nature, it is ideally suited to the cooperative sector.

In recent years, mills have been shifting towards southern and western states, especially Maharashtra, because the sugarcane grown there has higher sucrose content, the cooler climate ensures a longer crushing season, and cooperatives are more successful in these regions.
