Geography — World, India and Andhra Pradesh for Group-I · Chapter 8

Economic Geography: Sectors, Industry, Transport, Trade, Fishery and Forestry

What to remember

Economic activities are grouped into primary, secondary, tertiary, quaternary and quinary sectors; the share of the tertiary (service) sector grows as a country develops.
Industries locate near raw material, power, labour, market, transport and capital; AP's main industrial and port strengths lie around Visakhapatnam, Krishnapatnam and the Chennai-Visakhapatnam corridor.
Andhra Pradesh has a long coast, large aquaculture, important forests (Eastern Ghats, Nallamala, Seshachalam) and several ports, so fishery and forestry matter in its economy.

Sectors of the economy

Sector	Meaning	Examples
Primary	Direct use of natural resources	Farming, fishing, forestry, mining
Secondary	Making goods from raw materials	Steel, textiles, cement, food processing
Tertiary	Services	Transport, trade, banking, teaching, health, tourism
Quaternary	Knowledge based services and research	IT, data, research and development
Quinary	Top decision making	Senior managers, policy makers, scientists

Trend: As income grows, workers move from the primary sector to the secondary and then to the tertiary sector. In India the service sector gives the largest part of national income, while farming still gives work to a large share of people.
Organised and unorganised: Registered firms with fixed rules form the organised sector. Small, informal units form the unorganised sector.

Factors of industrial location

Raw material: Weight-losing materials (iron ore, sugarcane) pull industries to the source. Examples are steel near mines and sugar mills near cane fields.
Power and fuel: Coal, hydro and thermal power, gas and electricity.
Labour, capital and market: Skilled workers, banks and the nearness of buyers.
Transport: Ports, roads and railways reduce cost.
Government policy: Industrial corridors, special economic zones (SEZs) and incentives guide location.
Weber's theory: Industry is placed where transport cost is lowest, and then adjusted for labour cost and agglomeration (advantage of clustering).

Industrial regions of India

Region	Main industries
Hugli region	Jute, engineering, chemicals
Mumbai-Pune region	Cotton textiles, chemicals, engineering, IT
Ahmedabad-Vadodara region	Cotton textiles, petrochemicals, chemicals
Chota Nagpur plateau	Iron and steel, coal, heavy engineering
Chennai-Coimbatore-Bengaluru	Textiles, automobiles, electronics, IT
Visakhapatnam-Guntur	Steel, ship building, petroleum, fertiliser, cement, pharma

Industry in Andhra Pradesh

Visakhapatnam Steel Plant: A coastal integrated steel plant owned by Rashtriya Ispat Nigam Limited (RINL). It is near the port and gets ore and coal by sea and rail.
Visakhapatnam region: A refinery, shipyard, fertiliser, chemicals and pharma units.
Cement: Limestone in Guntur, Kurnool and Kadapa areas supports cement factories.
Sugar and agro-processing: Sugar mills, rice mills, oil mills and jute mills. Seafood and fruit processing units use local products.
Textiles and handlooms: Mangalagiri and Dharmavaram are known for handloom products.
Pharma and electronics: Clusters near Visakhapatnam (pharma city) and in the Tirupati-Sri City belt (electronics and manufacturing).
Industrial corridors: The Visakhapatnam-Chennai Industrial Corridor (VCIC) and the Chennai-Bengaluru and Hyderabad-Bengaluru corridors pass near AP.
SEZs: Special Economic Zones such as Visakhapatnam and Sri City attract exports.
Mineral base: Bauxite (Eastern Ghats), limestone, barytes (Cuddapah basin), asbestos, mica, beach sand and granite.

Transport

Roads: National Highways link major cities. The Golden Quadrilateral joins Delhi, Mumbai, Chennai and Kolkata, and passes through AP on the east-coast stretch. Roads carry most passengers and goods in India.
Railways: AP has a strong rail network on the east-coast trunk line. Vijayawada and Visakhapatnam are major railway junctions.
Ports: Visakhapatnam is a major port. Kakinada, Krishnapatnam and Gangavaram are important non-major ports. The Sagarmala programme aims at port-based development.
Air: International and domestic airports at Visakhapatnam, Vijayawada and Tirupati, and others at Rajahmundry and Kadapa.
Inland waterways: National Waterway 4 follows the Kakinada canal, Godavari and Krishna river stretches. The Buckingham Canal along the coast was once an important route.
Pipelines: Transport gas and oil from the Krishna-Godavari basin.
Importance: Transport links make markets, reduce prices and spread development.

Trade

Internal trade: Between states and within a state. Markets, mandis and ports help in this trade.
International trade: Exports (goods sent out) and imports (goods brought in). Balance of trade is the difference between the value of exports and imports.
India's exports: Engineering goods, gems and jewellery, petroleum products, textiles and agricultural products. Main imports are crude oil, gold, electronics and machinery.
AP exports: Seafood (shrimp), granite, tobacco and spices, rice, pharma and processed food.
Free trade and WTO: The World Trade Organization works to reduce trade barriers.

Fishery

Types: Marine fishing in sea waters, inland fishing in rivers and lakes, and aquaculture (fish and shrimp ponds).
AP: The long coast and the Godavari and Krishna deltas make AP a leading state in aquaculture, especially shrimp. Kolleru lake and the delta canals support inland fish farms.
Fishing harbours: Visakhapatnam, Kakinada, Machilipatnam and others.
Problems: Over-fishing, cyclones, water pollution, disease in shrimp ponds, and conflict between small boat fishermen and large trawlers.
Measures: Fishing ban in the breeding season (on the east coast, including AP, 15 April to 14 June), fish landing centres, cold storage, insurance and training. The Blue Revolution scheme supported the fishery sector; it was succeeded in 2020 by the Pradhan Mantri Matsya Sampada Yojana (PMMSY).

Forestry

Forest types in AP: Tropical dry deciduous (largest), tropical moist deciduous, thorn scrub in dry areas, and mangroves in the deltas.
Classification by law: Reserved forests (most protected), protected forests and unclassed forests.
Products: Timber, bamboo, tendu leaves (used for beedi), gum, honey, tamarind and medicinal plants. Red sanders (a rare tree known for its dark red wood) grows naturally in the Seshachalam hills of Rayalaseema and nearby areas. Its felling and trade are strictly regulated.
Protected areas: Sri Venkateswara National Park, Papikonda National Park and the Nagarjunasagar-Srisailam Tiger Reserve (among the biggest tiger reserves in India). Coringa and Pulicat have wildlife sanctuaries.
Policy: The National Forest Policy, 1988 aims to keep one third of the land area under forest or tree cover, and two thirds in hill areas. Joint Forest Management gives villagers a role in guarding forests.
Threats: Illegal felling, forest fires, shifting cultivation, mining and encroachment.

Linking activities: a coastal value chain

A coastal area such as Visakhapatnam combines many activities. A port brings in raw material, the steel plant and refinery process it, railways and roads carry the goods and services support all of them.
Agro-based chain: Farmers grow paddy, groundnut or fruit. Mills and food units process them. Cold stores and transport take the product to markets and ports. This creates jobs in all three sectors.
Aquaculture chain: Hatcheries supply seed, farmers raise shrimp, processing plants clean and freeze them, and ports send them abroad.
Why clusters form: When many firms gather in one place they share skilled labour, roads, power and suppliers. This gain is called agglomeration economy.
Industrial pollution: Factories can pollute air and water. Rules require effluent treatment and environmental clearance. Green belts around plants reduce the effect.

Tourism and services as a growth sector

Tourism: It is a tertiary activity that gives jobs to guides, hotel staff, transporters and craft makers. AP draws pilgrims (Tirupati, Srisailam, Simhachalam), beach visitors (Visakhapatnam coast), hill visitors (Araku) and heritage visitors (Amaravati, Lepakshi).
Information technology: IT and related services have grown in Visakhapatnam and other cities, along with banking, education and health care.
Employment pattern: Services need fewer raw materials and more skill, so they are suited to cities with good roads, airports and internet links.
Planning tools: Industrial policy, ease of doing business measures, single-window clearance and skill programmes help attract firms.
