Regional Economic Development (Case studies) | ISC Class 12 Geography Notes

This note covers the meaning of development, multilevel planning and planning regions, and three regional economic development case studies: area development in the Chhattisgarh region through mining, the silk industry and farming; the growth of the electronics industry in Bengaluru, its reasons, extent, linkages and problems; and the growth of Haldia port, its industries, its developmental history, its hinterland and the advantages and disadvantages it has brought to people and area. It also sets out the general factors that decide where an industry locates and compares the three cases.

What do we mean by development and planning regions?

The term development describes the state of a society and the process of change it undergoes.

In the years after the Second World War, development was treated as being the same as economic growth, measured by a rising gross national product (GNP) and per capita income.

Experience showed that even countries with high economic growth saw poverty increase because growth was unevenly shared, so by the 1970s ideas of "redistribution with growth" were added to the meaning of development.

By the 1980s, development had come to mean a wide-spread improvement in both the social and material well-being of people, covering health, education, equality of opportunity and political and civil rights, not income alone.

Growing concern about the environmental effects of industrial growth, raised in the late 1960s, led to the idea of sustainable development. The World Commission on Environment and Development (the Brundtland Commission) defined it in its 1987 report, Our Common Future, as:

Definition: sustainable development. "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

Because development is uneven over space, some areas remain economically backward even where resources exist, since development also needs technology and investment.

Planners therefore adopt a spatial perspective and mark out planning regions, areas treated as a single unit for the purpose of regional planning so that imbalances between regions can be reduced.

Two ideas sit behind this approach. Regional imbalance means the uneven pattern of development over space, in which some areas are more developed and some lag behind. Target area planning is the special care that the planning process has to take of areas that have remained economically backward.

Target area planning became necessary because, after about one and a half decades of planning experience, it was realised that regional imbalances in economic development were getting accentuated. In order to arrest the accentuation of regional and social disparities, the Planning Commission introduced the target area and target group approaches to planning.

Examples of programmes directed towards the development of target areas are the Command Area Development Programme, the Drought Prone Area Development Programme, the Desert Development Programme and the Hill Area Development Programme. The Small Farmers Development Agency (SFDA) and the Marginal Farmers Development Agency (MFDA) are examples of target group programmes.

How does multilevel planning work in India?

Planning in India uses two broad approaches. Sectoral planning means drawing up schemes for individual sectors of the economy, such as agriculture, power, transport or social infrastructure, without reference to area.

Regional planning takes a spatial view and aims to reduce regional imbalance in development, since there is no uniform level of economic development across the country.

India adopted centralised planning after independence and moved, over time, towards multilevel planning, in which the responsibility for formulating plans is shared between the Centre, states and districts rather than resting only at the top.

On 1 January 2015, the Planning Commission was replaced by the NITI Aayog, set up to involve the states in economic policy-making and to give strategic and technical advice to the Central and state governments.

Within this system, special attention is given to areas that remain backward even after general planning, through a target area approach.

Programmes such as the Drought Prone Area Programme, the Desert Development Programme and the Hill Area Development Programme are examples of target area planning, while the Small Farmers Development Agency and Marginal Farmers Development Agency are examples of target group planning directed at particular sections of people rather than whole areas.

1. National level: the NITI Aayog gives overall strategic and technical direction and coordinates policy between the Centre and the states.
2. State level: state planning bodies adapt national priorities to the state's own resources and problems.
3. District level: district plans bring together schemes for agriculture, infrastructure and welfare within the district.
4. Block level: block-level plans identify local needs such as irrigation, roads or schools for groups of villages.
5. Village or local level: panchayats and local bodies implement and monitor schemes at the ground level, closest to the people they serve.

This layered structure is what is meant by multilevel planning: each level deals with the scale of problem it is best placed to address, while regional and target area planning make sure that backward regions are not left out of the overall development process.

Case study: Area development in the Chhattisgarh region

Chhattisgarh lies on the eastern side of the Deccan plateau and is heavily forested, with a large tribal population and rich deposits of iron ore, coal, limestone and bauxite.

Its geographical location, astride mineral-bearing plateau country and fertile river plains, has shaped a pattern of regional development in which mining, a traditional silk industry and farming each play a part, though the benefits have reached different areas and groups unevenly.

What role do mining and the resource base play?

The region's resource base rests heavily on minerals. Iron ore from ranges such as Bailadila and Dalli-Rajhara has fed large integrated steel plants, while coalfields around Korba support thermal power stations and an aluminium industry.

Mining has brought jobs, railway links and township development, but it has also caused deforestation, displacement of tribal communities from their land, and pollution of air and water, which are the principal issues of development that mining-led growth has created in the region.

What is the role of the silk industry?

Chhattisgarh is known for tussar (kosa) silk, produced by silkworms reared in the open on sal and other forest trees rather than indoors on mulberry leaves.

The rearing of tussar cocoons and reeling of silk gives supplementary income to many tribal and forest-dependent households, linking the silk industry closely to the forest resource base of the region.

Because it uses local, low-cost inputs and existing skills, this industry has spread development benefits more widely among poorer rural households than mining has.

Why does farming remain central to the region?

The Chhattisgarh plain, with its heavy monsoon rainfall and fertile soils, is dominated by paddy cultivation, so much so that the state is often described as a major rice-growing region of the country.

Farming remains the main occupation for most of the population even where mining and industry have grown, so agricultural development and support to farmers remain central to the overall development of the region.

What issues of development has this uneven growth created?

The advantages of mineral-based industrial growth, such as employment, infrastructure and revenue, have been concentrated in a few mining and industrial districts.

Disadvantages, including land loss, displacement and environmental degradation, have fallen mainly on tribal and forest-dependent communities, while large parts of the state have continued to depend on low-productivity, rainfed farming.

This uneven spread of benefits and costs within a single state is itself an example of why regional planning, rather than sectoral planning alone, is needed.

On an outline map of Chhattisgarh, mark Raipur as the capital, the iron ore and coal belts in the east and north, a steel plant and power/aluminium centre, and the forested tribal districts associated with tussar silk rearing.

Case study: The electronics industry in Bengaluru

Bengaluru, the capital of Karnataka, is one of the clearest Indian examples of a regional economy transformed by a single modern industry.

Its geographical location on the Deccan plateau at a height of roughly 900 metres gives it a mild, pleasant climate, which, together with other advantages, has made it attractive for electronics and software activity.

Why did Bengaluru develop as an electronics centre?

Several factors came together to favour Bengaluru. Public sector electronics and aerospace units such as Bharat Electronics Limited, Hindustan Aeronautics Limited and the Indian Space Research Organisation were established there in the decades after independence, building up a base of skilled technical workers.

Premier institutions, including the Indian Institute of Science and a number of engineering colleges, provided a continuing supply of trained scientists and engineers.

Government policy, through schemes to promote software exports and the creation of dedicated technology parks, encouraged private firms to locate there, and the pleasant climate helped attract skilled staff from elsewhere in India.

What is the extent of the electronics industry in Bengaluru?

Growth accelerated from the 1980s and 1990s as private software companies expanded rapidly, and Bengaluru came to be popularly described as the "Silicon Valley of India".

The industry is not spread evenly over the city. It is clustered in and around dedicated technology parks and industrial estates on the city's outskirts, such as Electronics City in the south-east and Whitefield in the east, where electronics hardware units, software firms and research and development centres sit close together.

Its scale is best seen in its share of national activity: Bengaluru accounts for a very large share of the country's software exports and of its electronics and information technology employment, and the industry is the main source of jobs for the city's large body of trained engineers and technicians.

What is the extent of its national and international linkages?

Its national linkages include supplying software and electronic hardware services to firms and government departments across the country, while its international linkages are built on exporting software services to clients in North America, Europe and elsewhere, and attracting research and development centres set up by multinational technology companies.

What problems has this rapid growth caused?

Rapid, concentrated growth has strained the city's infrastructure. Traffic congestion, pressure on water supply, rising real estate costs and periodic power shortages are among the problems that have accompanied Bengaluru's growth as an electronics and software centre, illustrating how a successful regional industry can outgrow the civic infrastructure built to support it.

On an outline map of Karnataka, mark Bengaluru, note its location on the Deccan plateau, and label it as a centre of electronics and software linked by export routes to national and international markets.

Case study: The growth of Haldia port

Haldia lies on the west bank of the Hooghly river in West Bengal, close to where the river meets the Bay of Bengal and some distance downstream from Kolkata.

Its development is closely tied to the problems of its older neighbour: the Hooghly above Haldia suffers from heavy silting, which made it increasingly difficult for large ocean-going vessels to reach Kolkata port.

What is the developmental history of Haldia?

Haldia began as a small riverside settlement near the mouth of the Hooghly. Its growth into a port and industrial town came in stages after independence, as planners looked for a deep-water outlet to supplement the congested and silting port of Kolkata.

The decisive steps came in the 1970s. An oil refinery began working at Haldia in 1975, and the Haldia Dock Complex, which lets large vessels berth far downstream of Kolkata, opened in 1977. The port was linked by rail and road to Kolkata and to the coalfield and industrial belt of eastern India.

A petrochemical complex and fertiliser units followed, turning Haldia from a port alone into an industrial township. Later expansion added facilities for handling bulk and liquid cargo, so that the port and its industries grew together.

How did the port grow?

To overcome this limitation, Haldia was developed as a subsidiary, deep-water port able to handle larger ships than could reach Kolkata, extending the port system further down the Hooghly towards the open sea.

The Haldia Dock Complex was built to handle both bulk cargo and liquid cargo such as petroleum products.

What industries developed at Haldia?

Haldia grew as an industrial township alongside its port facilities. A major oil refinery was established there, together with a petrochemical complex and fertiliser units, so that petroleum products, petrochemicals and fertiliser became central to the port's cargo and to the local economy.

The presence of the refinery and petrochemical plant means the port handles large volumes of crude oil imports and refined products together with general and bulk cargo.

What is Haldia's hinterland?

As an outlet for eastern India, Haldia's hinterland, the inland area it serves for trade, extends across West Bengal, Bihar, Jharkhand and parts of eastern Uttar Pradesh, and also serves landlocked Nepal, giving the port an importance well beyond West Bengal alone.

What advantages and disadvantages has Haldia brought to people and area?

For the people of the area, the port and its industries have brought employment in dock work, oil refining, petrochemicals and fertiliser production, along with better roads, railways, schools and health facilities in and around the township.

The area has gained a large industrial base and a busy port that earns foreign exchange and serves a wide hinterland, so land values and trade activity have risen.

The disadvantages are equally real. The industries and heavy cargo traffic have caused air and water pollution in the Hooghly and its surroundings, and the growth of the port has taken over farmland and fishing grounds, displacing people who depended on them.

Traffic congestion and pressure on housing and water supply have grown with the township, so the benefits of Haldia's development have not reached everyone in the area equally.

On an outline map of eastern India, mark the Hooghly river, Kolkata and Haldia downstream of it, and shade the hinterland states of West Bengal, Bihar, Jharkhand, eastern Uttar Pradesh and Nepal that the port serves.

What factors generally decide where an industry locates?

The three case studies above can be better understood against the general factors that decide industrial location.

Industries try to minimise costs, so access to a large market, meaning people with both demand and the purchasing power to buy the goods, is one of the most important factors.

Access to raw material matters most where the material is bulky, cheap or perishable, since it is then cheaper to process it close to its source, as with mining-based industry in Chhattisgarh or the refinery at Haldia.

Access to labour supply, particularly skilled labour, explains much of Bengaluru's advantage, since increasing mechanisation elsewhere has reduced the importance of simple labour supply for many industries.

Access to sources of energy favours industries located near coal, hydroelectricity or petroleum, which is relevant to Chhattisgarh's coal and power-based industry.

Good transport and communication links are essential for carrying raw material in and finished goods out, which is exactly the role that port facilities play at Haldia.

Government policy can also draw industries to particular areas through deliberate regional policies, as seen in the public sector units and software-export incentives that helped Bengaluru grow, and in planned mining and steel development in Chhattisgarh.

Finally, many industries benefit from agglomeration economies, savings that come from being located near related industries and shared infrastructure, which helps explain why electronics and software firms have continued to cluster in Bengaluru once the first units were established there.

These factors operate together to determine industrial location, and no single one explains a region's pattern of industry on its own.

How do the three regional case studies compare?

Although Chhattisgarh, Bengaluru and Haldia grew for different reasons, placing them side by side shows how geographical location, resource base and government policy combine differently in each case to shape the pattern of development and its problems.

Chhattisgarh's growth rests chiefly on a mineral resource base, mined in a few districts, supplemented by a forest-based tussar silk industry and by paddy farming spread across the state. Its principal issue of development is the unequal spread of benefits between mining districts and the wider tribal and rainfed-farming population.

Bengaluru's growth rests instead on a human resource base: skilled labour, scientific institutions and early public sector units, reinforced by government policy on software exports and helped by a favourable climate. Its principal issue of development is the strain that rapid, concentrated growth has placed on city infrastructure.

Haldia's growth rests on its geographical location on the Hooghly, downstream of a silting Kolkata, and on the industries, oil refining, petrochemicals and fertiliser, built around its port. Its development is best understood through the hinterland it serves rather than through resource base or labour supply alone.

Seen together, the three cases confirm why planners separate sectoral planning from regional planning: a sector, such as mining, electronics or port trade, can grow strongly in one location while leaving neighbouring areas, or other groups within the same area, without a matching share of the benefits.

Going beyond the syllabus

These ideas extend the unit and are not needed for the questions on it.

How do initial advantages reinforce regional growth?

The three case studies illustrate a wider pattern in regional development: an initial advantage, whether a mineral deposit, a pool of skilled workers, or a navigable river, can set off a self-reinforcing cycle of growth in one place, while nearby areas with fewer such advantages lag behind.

This is one reason planners use target area and multilevel planning approaches rather than relying only on sectoral schemes, since sectoral planning alone does not correct imbalances between regions.

It is also useful to notice that the general factors that decide industrial location, access to market, raw material, labour, energy, transport and government policy, apply unevenly to different regions depending on what each region already has. A region rich in minerals, such as Chhattisgarh, attracts mining and mineral-based industry first, while a region rich in skilled workers and institutions, such as Bengaluru, attracts knowledge-based industry instead, and a region favoured by river and coastal location, such as Haldia, attracts port-dependent industry.

This means the same broad planning tools, target area programmes, target group programmes and multilevel planning through the Centre, states, districts, blocks and villages, have to be applied differently in each kind of region if they are to actually reduce, rather than simply record, the regional imbalance in development that follows from such uneven starting advantages.

Q5. Why was Haldia developed as a port, and what does it mainly handle? [4 marks]

1. Haldia was developed because heavy silting of the Hooghly river above it made it increasingly difficult for large ocean-going vessels to reach Kolkata port.
2. It was built as a subsidiary, deep-water port further down the Hooghly, able to handle ships that could not reach Kolkata.
3. An oil refinery, a petrochemical complex and fertiliser units were established alongside the port, so the port mainly handles petroleum products, petrochemicals and fertiliser, together with other bulk cargo.

Q7. Evaluate the advantages and disadvantages that area development has brought to the people of the Chhattisgarh region through mining, the silk industry and farming. [7 marks]

1. Chhattisgarh's resource base of iron ore, coal and other minerals has supported mining and industrial growth, including an integrated steel plant and a coal and aluminium hub, which have brought employment, railway links and township development to a few districts.
2. This mining-led growth has also caused significant disadvantages: deforestation, displacement of tribal communities from their land, and pollution of air and water in and around the mining areas.
3. The tussar (kosa) silk industry, by contrast, uses the existing forest resource base and skills of tribal households, giving a supplementary income to many poorer rural families without the same scale of displacement seen in mining.
4. Farming, mainly paddy cultivation on the fertile, monsoon-fed Chhattisgarh plain, remains the main occupation for most of the state's population and so continues to matter for overall regional development even where mining and industry dominate the economy.
5. The benefits of mineral-based industrial growth, such as jobs, infrastructure and revenue, have been concentrated mainly in a few mining and industrial districts rather than spread evenly across the state.
6. The costs of this growth, including land loss and environmental degradation, have fallen disproportionately on tribal and forest-dependent communities.
7. Taken together, the case shows that area development can raise overall output while leaving serious issues of displacement, environmental damage and unequal regional benefit, which is why such uneven development needs continued attention through regional planning.

Q8. Evaluate the advantages and disadvantages that the growth of the port and its industries has brought to the people and area of Haldia. [7 marks]

1. The port and its industries have brought employment in dock work, oil refining, petrochemicals and fertiliser production to the people of the area.
2. Better roads, railways, schools and health facilities have developed in and around the township as it has grown.
3. The area has gained a large industrial base and a busy port that earns foreign exchange and serves a wide hinterland, so land values and trade activity have risen.
4. On the disadvantage side, the industries and heavy cargo traffic have caused air and water pollution in the Hooghly and its surroundings.
5. The growth of the port has taken over farmland and fishing grounds, displacing people who depended on them.
6. Traffic congestion and pressure on housing and water supply have grown with the township.
7. Overall, the benefits of Haldia's development have not reached everyone in the area equally, so the case shows that port-led growth must be judged by how its gains and costs are shared among people and places.

Q9. On an outline map of eastern India, mark and label Kolkata and Haldia, and name the river on which both stand. [1 mark]

1. Kolkata and Haldia are marked on the Hooghly river, with Haldia downstream of Kolkata.

Test yourself

What distinguishes regional planning from sectoral planning?

Sectoral planning targets a sector of the economy without reference to area, while regional planning takes a spatial view of a defined area to reduce imbalance in development.

Which body replaced the Planning Commission, and when?

The NITI Aayog replaced the Planning Commission on 1 January 2015, to advise the Centre and states on economic policy.

How does tussar silk rearing differ from ordinary mulberry silk rearing?

Tussar silkworms are reared in the open on forest trees such as sal, whereas mulberry silkworms are reared indoors on mulberry leaves.

Why does Chhattisgarh's mining-led growth create issues of development?

It has caused deforestation, displacement of tribal communities and pollution, even while bringing employment and infrastructure to mining districts.

Name factors that favoured the growth of the electronics industry in Bengaluru.
