Industrial Regions - India

Major Industrial Regions

The Mumbai-Pune Industrial Region

This is the country’s major industrial area. The region grew following the entrance of the British in India, who built the Mumbai harbor. The sea route between India and Europe was significantly restricted once the Suez Canal opened in 1869. The history of the cotton textile industry in India is intertwined with the growth of this industrial region.

The humid environment, natural port facilities, availability of hydro-power, skilled labor, and a wide cotton-producing hinterland all played important roles in the development of this industrial region. Only in Greater Mumbai are around 8000 registered factories, 350 of which are cotton textile companies. The region’s other industries include engineering products, chemical industries, food processing industries, leather goods, pharmaceutical industries, and film industries.

The majority of the output in Mumbai is light-textured, fine, and ultra-fine cotton fabrics. This region’s industrial sector employs around 15 lakh people. Pune is the region’s second most important industrial center. It is home to about 1200 registered industries. Its industries manufacture metallurgical, chemical, engineering, and automotive products. Pune has two plants that manufacture scooters and mopeds. This industrial zone has nearly reached saturation. Among the major issues confronting this industrial zone are:

  • Inadequate power supply
