Model Answer:

Introduction: India's leather industry, a major contributor to exports and employment, is geographically concentrated in specific regions. This concentration stems from various historical, economic, and policy factors, but also poses significant environmental challenges.

Body:

Factors responsible for concentration:

• Historical factors:

• • • Traditional leather-working communities in certain areas
    • Colonial-era establishment of tanneries in specific locations Example: Kanpur's leather industry dates back to the 19th century when the British set up factories to supply leather for their army.

• Availability of raw materials:

• Proximity to cattle-rearing areas

• Access to water bodies for processing Example: Tamil Nadu's leather industry benefits from the state's large cattle population and access to rivers like the Palar.

• Skilled labour:

• Generational knowledge transfer in leather-working communities

• Concentration of skilled workers attracting more industry Example: Kolkata's Bantala Leather Complex employs over 100,000 skilled workers from surrounding areas.

• Infrastructure:

• Development of leather clusters and special economic zones

• Proximity to ports for export Example: The Leather Complex in Jalandhar, Punjab, provides common effluent treatment plants and other shared infrastructure.

• Government policies:

• State-specific incentives for leather industry

• Establishment of leather technology institutes in certain regions Example: The Central Leather Research Institute in Chennai has boosted Tamil Nadu's leather sector through research and training.

Specific regions of concentration:

• Tamil Nadu: Chennai, Ambur, Ranipet, Vaniyambadi 
• West Bengal: Kolkata 
• Uttar Pradesh: Kanpur, Agra 
• Maharashtra: Mumbai 
• Punjab: Jalandhar

Environmental challenges posed by concentration:

• Water pollution:

• • • Discharge of untreated effluents into water bodies
    • Contamination of groundwater Example: The Ganges River near Kanpur has high levels of chromium and other pollutants due to tannery waste.

• Air pollution:

• • • Emission of harmful gases during leather processing
    • Odor problems in surrounding areas Example: Residents near tanneries in Vellore, Tamil Nadu, have reported respiratory issues due to air pollution.

• Solid waste generation:

• Accumulation of leather scraps and sludge

• Improper disposal leading to soil contamination Example: The Pallavaram tannery belt in Chennai generates about 100 tons of solid waste daily.

• Health hazards:

• Occupational health risks for workers

• Increased disease incidence in nearby communities Example: A study in Kanpur found higher rates of skin and respiratory diseases among tannery workers compared to the general population.

• Land degradation:

• Soil salinization due to chemical-rich effluents

• Loss of agricultural productivity in surrounding areas Example: Farmers near the Palar River basin have reported decreased crop yields due to tannery pollution.

Conclusion: While the concentration of India's leather industry has economic benefits, it poses serious environmental challenges. Implementing stricter regulations, promoting cleaner technologies, and encouraging industry decentralisation can help balance economic growth with environmental sustainability.
