Agriculture in Tamil Nadu


Most of the people of Tamil Nadu depended on agriculture at the time of independence and even after 40 years of independence. That situation is being changed in the recent years. It has been noticed that the number of farmers in Tamil Nadu has got reduced during the last 10 years according to the 2011 census data. Similarly the number of agricultural workers also reduced during the same period. According to the 2001 census, 49.3% out of the total population of workers were involved in agriculture. The percentage has reduced to 42.1 in the next 10 years. In 2011 there were three crore 29 lakh workers in Tamil Nadu of which 96 lakh were agricultural workers.

In 2011, nearly 55% of the women were involved in agriculture whereas nearly one third (35.3%) of the male population was involved in agriculture during the same year.

Sectors of people involved in agricultural activities

A major portion of the workers involved in agricultural activities are landless labourers. All the land holders do not have the same amount of land. Many have very little land and very few people hold large areas of land.

During 2015-16 , there were 79,38,000 cultivators in Tamil Nadu. But five years earliers there were 81,18,000 cultivators. There was a reduction of 1,80,000 cultivators in these five years. Similarly, the area under cultivation also reduced from 64.88 lakh hectares to 59.71 lakh hectares during the same period. That is, the state of Tamil Nadu had lost nearly 1,03,400 hectares on an average during these five years.

Most of the cultivators in Tamil nadu are micro farmers who cultivate in an area less than 1 hectare. Micro farmers account to around 78% of the total cultivators, while the area cultivated by these micro farmers is just 36%. Small farmers cultivating 1-2 hectares of land cover 14%, while the land cultivated by them is 26%.

Cultivators of schedule caste farmers are only one percent in Tamil nadu. 96% of this one percent are small, micro farmers.The total land area

under agriculture is shrinking fast not only in Tamil nadu, but also throughout India. The number of marginal farmers has increased in India. In contrast, the number of marginal farmers is decreasing in Tamil Nadu. This shows that the farmers are doing other occupations.

Types of land usage

The total geographical area of Tamil Nadu is one crore 30 lakhs and

33 thousand hectares. Out of this only one third of land is used for agriculture (45,44,000 hectare). 17% of the land is used for non agricultural use. Nearly the same size ( 2125 thousand hectares) of land are forests. About 4% of the total land is unusable. One tenth of the land is barren. Other fallow lands are 13 percent. So nearly one-fourth of the land is barren and we have to be concerned of the increasing size of the barren land. Grazing land and cash crops occupy slightly more than 5% of the total land area.

The size of the total cropping land in Tamil Nadu is 4,544 thousand hectare and this keeps on changing every year. Sufficient rains at the proper period will increase this extent of land. Failure or shortage in rainfall leads to the reduction of land usage for cultivation. A small part of this area gives a chance to crop more than once in a year. The extent of this area also changes every year. This land extent was 9 lakh hectare in next year but was reduced to 6 lakh hectare, due to lack of rainfall. This area will be more or less stable only when there is a stable and reliable water source.In 2012-13, out of the total cultivated land, nearly 72 percent is used for food crops and the remaining for non-food crops.

Water Resource for Agriculture

There are no perennial rivers in Tamil Nadu. Tamil Nadu receives the required water from the Northeast and Southwest monsoons. When the South West monsoon rains are high in the catchment areas of the Cauvery River in Karnataka dams get filled and in turn the Cauvery river in Tamil Nadu gets water.

Northeast monsoon (Oct-Dec) is a major source of water for Tamil Nadu. The Northeast monsoon rains are stored in reservoirs, lakes, pond and wells for cultivation. Conventional water bodies like lakes, ponds and canals provide water for agriculture in Tamil Nadu. 2,239 canals run through Tamil Nadu covering a length of 9,750 km. There are 7,985 small lakes, 33,142 large lakes, 15 lakh open wells and there are 3,54,000

borewells in the state where agriculture is carried out with the help of these water resources.

The area of land that is irrigated using water from lakes is very low. Nearly 3.68 lakh hectares of land obtain water from lakes. The canals provide water to 6.68 lakh hectares. Borewells irrigate 4.93 lakh hectares and open wells provide water to 11.91 lakh hectares of land.

Agriculture in Tamil Nadu is dependent mostly on groundwater. Use of ground water for agriculture creates many hardships too. There would be no sufferings if the amount of water taken from the underground and the amount of water that goes into the underground during the rainy season are equal. On the contrary, as the amount of water taken increases, the ground water goes down resulting in complete dryness or change into unusable water. The Union Ground Water Board is constantly monitoring the level and nature of ground water. From this, we come to know that:

  1. Tamil Nadu agriculture is dependent on
  2. It is   very   urgent   and   necessary  to   regulate  the   usage   of underground                 
  3. This is very important for sustainable

The area under irrigation is about 57 percent of the total area under cultivation.

Virtual water

The term ‘virtual water’ was introduced by Tony Allen in 1990. The water consumed in the production process of an agricultural or industrial product is called ‘virtual water’. It is the hidden flow of water when food or other commodities are traded from one place to another. For instance, it takes 1340 cubic metres of water (based on the world average) to produce one metric ton of wheat. That is, if one metric ton of wheat is exported to another country, it means that 1340 cubic metres of water used to cultivate this amount of wheat is also being exported. India is the largest global freshwater user. India has been the fifth largest exporter of virtual water in the world.

Irrigation and Crop types

Crops in Tamil Nadu

All cultivated crops can be classifi ed as food crops and non-food crops. 57 percentage of the total land under food grain cultivation is irrigated. In 2014-15, 59 percentage of food crops and 50 percentage of non food crops were irrigated in Tamil Nadu. The total area of land cultivated in Tamil Nadu was 59 lakh and 94 thousand hectares in 2014- 2015. Out of this non-food crops were 76%. Paddy cultivation is carried out at a large scale of 30 percent cultivated land area and other food crops in 12 percent area. Millets are cultivated in a very low percentage of area. Sorghum (Cholam) cultivation in 7 per cent land area, cumbu in one percent and ragi in 1.7 per cent. Other millets occupy 6 per cent in the year 2014 – 2015.

The area cultivatable land changes every year as a result of many factors such as rainfall, availability of water, weather and market prices.

  • River Cauvery is the 3rd largest river in South India. Its length is 765 km.
    • The dams constructed across Cauvery in Tamil Nadu are Mettur Dam, Kallanai

Micro irrigation

Micro irrigation technology is a very good remedial measure to tackle shortage in irrigational water. Th is irrigation technology helps to have a higher yield when compared to the traditional irrigation methods. As only required amount of water is supplied at regular intervals, it increases the ability of water usage and productivity of the crop resulting in reduction of labour expenses and weed growth in the fi eld. As the fertilizer is distributed through water, it increases the usage of fertilizer and the yield. As Tamil Nadu gets insufficient rainfall, the government has taken many measures to implement micro irrigation for proper distribution of water to crops that require more water.

Decadal growth in agricultural production

The total quantity of food grains produced in Tamil Nadu in the year 2014 – 2015 was one crore 27 lakh 35 thousand tonnes. Paddy alone accounted to 80 lakhs tonnes. The contribution of paddy to the total amount of food production is 62%. Maize production was 20%, corn 7%,

ragi 3% and another 3% occupied by black gram, while other food crops contributed a very meager amount to the total food production in Tamil Nadu.

The amount of production varies depending on the amount of land being cultivated.

The yield of productive crops

The amount of production depends not only on the area but also on the productivity of crops. Production capacity of paddy in Tamil Nadu was 4,429 kg per hectare in 2014-2015. This capacity was 3,039 kilograms in 2010-2011 revealing the increase in productivity.Next to paddy, maize stands second in the production (8,824 kg/hectare).2,093 kg/hectare corn, 3,077 kgs of rye (cumbu) and 3348 kgs of ragi were produced during the same period.

Black gram, one of the largest cultivated pulses, produced 645 kg per hectare. Production of sugarcane and ground nut (Manila) were 107 tons and 2,753 kg per hectare respectively.The productivity of crops continues to increase. For example the productivity of paddy in 1965 – 66 was 1,409 kg. It increased to 2,029 kg in 1975-76 and 2,372 kg in 1985-86. It increased to 2,712 kg after a decade. The production was 4,429 kg in the year 2014-15. In the past fifty years, the productivity of paddy has increased more than three times.

The food grain production capacity, has increased about 3.5 times between 1965-66 and 2014-15.We find that both the productivity and food production in Tamil Nadu continue to increase. However, the area under food grain cultivation has reduced in the same period. Though there was a reduction in the area of production, the total amount of production has been maintained and there is an increase of productivity.

Industrial Clusters in Tamil Nadu Introduction – Industrialisation

Generally, “any human activity which is engaged in the conversion of raw materials into readily usable materials is called an industry”.Industrialisation refers to the process of using modern techniques of production to produce goods that are required by both consumers and other producers on a large scale. While some consumer goods such as phones and television sets meet the requirements of consumers, industries also produce goods like components, machine parts and machines that are required by other producers. 

The historical process of a steady increase in the number and scale of manufacturing in a country exists for a long time. It is important for several reasons.In this chapter we will learn the nature of industrialisation of Tamil Nadu, importance of industrial clusters, how industrial clusters have developed in Tamil Nadu and the role of government initiatives in promoting industries.

Importance of Industrialisation

To understand importance of industries,we need to understand why the share of agriculture in an economy’s income and employment decreases with development.First, demand for food remains constant with regard to income. Therefore, as an economy grows and incomes increase,  consumers tend to spend a lesser share of their income on products from the agricultural sector.

Second, even the food that is consumed is subject to more transformation as an economy expands and there is greater division of labour between people and between regions. Food products are taken over longer distances,processed and branded. This also requires that food products have to be preserved. As a result,the prices that farmers get tend to be much less compared to the prices at which consumers buy.

Third, there are limits to the ability of agriculture to absorb labour due to the declining marginal productivity of land. As a result, labour productivity  in the agricultural   sector cannot increase much. Wages too cannot therefore increase and as a result poverty levels may remain high, especially when more and more people continue to rely on agriculture for their livelihood.

Due to all these factors, there is a need for an economy’s production and employment base to diversify away from agriculture.Development economics therefore recognizes the need for structural transformation of the economy where the share of non-agricultural sectors tend to get increase steadily. Such transformation and diversification through industrialisation is therefore seen as important for an economy’s development.

What benefits does industrialisation bring to an economy?

As stated earlier, it is essential to produce inputs to other producers in an economy. Even agriculture requires inputs from industry such as fertilisers and tractors to increase productivity.

Second, a market exists for both producers and consumer goods. Even services like banking, transport and trade are dependent on production of industrial goods.

Third, by using modern methods of production, industries contribute to better productivity and hence lower cost of production of all goods produced. It therefore helps people to buy goods at a cheaper rate and

help create demand for more products.

Fourth, through such expansion of production, industrialisation helps to absorb the labour force coming out of agriculture.Employment generation is therefore an important objective of industrialisation.

Fifth, a related advantage of industrialization is therefore technological change. Through use of modern techniques, industrialisation contributes to learning of such methods and their improvement. As a result labour productivity, ie,output per unit of labour input increases, which can help workers earn higher wages.

Sixth, expanding incomes lead to more demand for goods and services. If an economy is not able to produce enough to meet such demand, it has to rely on imports and therefore spend a lot of foreign exchange. If the economy does not earn enough from exporting, it will

be difficult to meet the growing demand. Industrialisation therefore helps an economy to save and also generate foreign exchange through exports.

Types of Industries

Industries can be classified on the basis of

  • Users: If the output is consumed by the final consumer, it is called a consumer goods sector. If the output is consumed by another producer, it is called a capital goods sector. There are industries that produce raw materials for other industries such as cement and steel. Such industries are called basic goods
  • Type of Inputs Used: Industries are also classified based on the kind of raw material used such as agro-processing, textiles sector,rubber products, leather goods,
  • Ownership: Firms may be privately owned, publicly owned (by the government, central or state), jointly owned by the private and public sector, or cooperatively owned (cooperatives).

Size: Firms may be large, small or medium based on their volume of output, sales or employment or on the basis of the amount of investments

made. The Indian government normally uses the investment criterion to decide whether a firm is small, medium or large. There are also micro or tiny enterprises that are smaller than even small firms. This classification is important because the government often provides financial,infrastructural or subsidy support to the smaller firms to promote them.

The small sector is seen as important for two reasons. One, it is believed to generate more employment than the large-scale sector, which is likely to use more advanced and automated technologies and therefore may not generate enough employment. Second, the small scale sector allows for a larger number of entrepreneurs to emerge from less privileged backgrounds.

Till the 1980s, it was widely believed that large firms are more efficient and can outcompete the smaller firms. But at present, based on experiences of industrialisation in different parts of the world, it is believed   that   when    small   firms   specialising   in   one    sector   are geographically concentrated in specific locations, and linked to one another through production and learning, they tend to be equally if not more efficient than large scale enterprises. Such agglomerations of small firms are called industrial clusters.

Industrial Clusters

Industrial clusters are groups of firms in a defined geographic area that share common markets, technologies and skill requirements.An important aspect of clusters is the nature of inter-firm networks and interactions. Clusters where firms specialise in one stage of the production process and supply inputs or absorb the output of another firm in the cluster is critical to the efficiency and competitiveness of the cluster. The advantages of industrial clusters or districts was first observed by the

famous economist Alfred Marshall in the 1920s when he tried to understand the working of clusters of small firms in the metal-working and textile regions in England. While the notion of an ‘industrial district’ was developed

by Marshall, it was only after the success of small firms in Italy in the 1980s that it became popular. Policy-makers in developing countries like India began to promote them actively as they realized that there several such small firm clusters in the country.

The following are the chief characteristics of a successful cluster. 

  • geographical proximity of small and medium enterprises (SMEs)
  • sectoral specialization
  • close inter-firm collaboration
  • inter-firm competition based on innovation
  • a socio-cultural identity, which facilitates trust
  • multi-skilled workforce
  • active self-help organisations, and
  • supportive regional and municipal

Firms are therefore expected to collaborate and compete with one another at the same time. By collaborating, they can expand their capacity and also learn from one another. Through competition, they are forced to become more efficient. Apart from the Chennai region, industrial growth has been concentrated in several small town clusters, throughout the state, with the western region being more dominant. These clusters specialise in a range of activities like clothing, home furnishings, textiles, leather, poultry, coir products, transport equipment servicing, engineering services and auto component making.

How Do Clusters Originate?

Clusters may arise due to many factors.Certain clusters evolve over a long time in history when artisans settle in one locality and evolve over centuries. Handloom weaving clusters are one examples of this development. Or else, in some sectors, when a large firm is established, a cluster of firms may emerge to take care of its input and service requirements. At times, governments may decide to encourage manufacturing using raw materials from a region, which may also lead to emergence of clusters.

Historical Development of Industrialisation in Tamil Nadu

There is lot of evidence for presence of industrial activities such as textiles, shipbuilding,iron and steel making and pottery in precolonial Tamil Nadu. Given the vast coastline, the region has been involved in trade with both South-East and West Asia for several centuries. Colonial policies also contributed to the decline of the handloom weaving industry due to competition from machinemade imports from England. But some industries also developed during the colonial period and provided the basis for subsequent industrialisation in the state.

Industrialisation in the Colonial Period

There are two sets of factors that have contributed to the process. The introduction of cotton cultivation in western and southern Tamil Nadu by the colonial government led to the emergence of a large-scale textile sector in these parts, which involved ginning, pressing, spinning and weaving operations. The introduction of railways also expanded the market for cotton yarn and helped develop the sector.

Second, increase in trade during this period led to industrial development around two of the most active ports in the region,Chennai and Tuticorin. The Chennai region also saw the beginning of the automobile sector during this period along with leather. The growth of jaggery industry in south Tamil Nadu is another example of this. Match factories too emerged during the colonial period in the Sivakasi region, which later on became a major centre for fireworks production and printing. Port-related activity too contributed to the growth of the region. Leather production was also taking place in Dindigul, Vellore and Ambur areas.

In Western Tamil Nadu, the emergence of textiles industries also led to demand and starting of textile machinery industry in the region. This textile machinery industry in turn led to the rise of a number of small workshops for repair and producers of machinery components. Another major development in the western region is the introduction of electricity from hydro-electric power in the 1930s. Availability of electricity allowed for use of oil engines for drawing ground water.

This led to both expansion of agriculture as well as increase in demand for oil engines.In turn, it led to emergence of workshops for servicing engines and also for addressing the demand for spare parts. Foundries began to be set up and agricultural machinery began to be produced.

Post-Independence to early 1990s

Soon after independence, several large enterprises were set up by both the central and state governments in different segments such as the Integral Coach Factory in Chennai to make railway coaches and the Bharat Heavy Electricals Limited (BHEL) in Tiruchirapalli manufacture to boilers and turbines. BHEL in turn led to the emergence of an industrial cluster of several small firms catering to its input requirements. Heavy Vehicles Factory  was  set  up  to  manufacture  tanks  in  Avadi  on  the  outskirts of

Chennai.  Standard  Motors  too    started  manufacturing  cars  in Chennai.


Ashok Motors (later Ashok Leyland) and Standard Motors together helped form an automobile cluster in the Chennai region. The Avadi industrial estate was established in the 1950s to support the small and medium companies supplying to the large firms in the region.More hydro-electric power projects in the state were also initiated to increase the spread of electrification. The government played a major role in all these processes. The Salem Steel Plant was set up in 1973 to produce stainless steel. The Coimbatore region also witnessed diversification from textiles to textile machinery as well as agricultural machinery like electric motors and pumpsets for drawing ground water.

The 1970s and 1980s saw the setting up of emergence of powerloom weaving clusters in the Coimbatore region as well as expansion of cotton knitwear cluster in Tiruppur and home furnishings cluster in Karur. This period also saw more encouragement of the small and medium sector with setting up of industrial estates by the state government in different parts. The Hosur industrial cluster is a successful case of how such policy efforts to promote industrial estates helped develop industries in a backward region.

Industrialisation in Tamil Nadu – Liberalization Phase

The final phase of industrialisation is the post-reforms period since the early 1990s. The reforms made the state governments more responsible for resource mobilisation and they were forced to compete with each other to attract private investments for industrialisation. Incentives such as cheap land, tax concessions and subsidised but quality power were all offered to woo investors. Trade liberalisation and currency devaluation also helped open up export markets. This led to two major developments.

First, because of trade liberalization measures, exports of textiles, home furnishings and leather products began to grow rapidly.Second, efforts to attract investments led to entry of leading multinational firms (MNCs) into the state, especially in the automobile sector. Since automobile sector relies heavily on component makers, entry of MNCs not only brought along other MNC component suppliers but also opened up new market opportunities for domestic component producers. Chennai region also emerged as a hub for electronics industry with MNCs such as Nokia, Foxconn, Samsung and Flextronics opening plants on the city’s outskirts.

A significant share of these investments has come up in special economic zones in the districts bordering Chennai. Tamil Nadu has often been hailed as a model for successfully using the SEZ route to attract productive  investments.  Other   important  industries  in   the  state   that evolved over a much longer period include sugar, fertilizers, cement, agricultural implements, iron and steel, chemicals, transformers and paper. Because of all these factors, Tamil Nadu at present has the largest number of factories among all states in India and also has the largest share of workforce employed in manufacturing. Importantly, it is more labour intensive compared to other industrially advanced states like Maharashtra

and Gujarat.

The major industries are automobiles, autocomponents,light and heavy engineering,machinery, cotton, textiles, rubber, food products, transport equipment, chemicals, and leather and leather goods. Unlike other states, the industries are spread across all regions of the state (there are 27 clusters in 13 districts) with many of them being export oriented as well. The state has a well-developed network of roads, rail, air and major ports.

The diffusion of industrialisation also implies a widening of the social base of entrepreneurship. Unlike in North India where entrepreneurs and business groups are drawn mostly from merchant communities, in Tamil Nadu, the entrepreneurs come from a dispersed social background,with a relatively small size of capital. Further, the spatial spread of industries is higher. The state also has a better mix of large, small and household industries. This diffused process of industrialisation and corresponding urbanization has paved the way for better rural-urban linkages in Tamil Nadu than in most other states. 


Automotive Clusters

Chennai is nicknamed as “The Detroit of Asia” because of its large auto industry base. Chennai is home to large number of auto assembly and component making firms. While there were a few domestic firms like TVS, TI Cycles, Ashok Leyland and Standard Motors earlier, in the postreform period, several MNC firms like Hyundai,Ford, Daimler-Benz and Renault-Nissan have opened factories in the region. This in turn has attracted a number of component suppliers from foreign countries. Many local firms too cater to component production for all these firms.

Hosur is another auto cluster with firms like TVS and Ashok Leyland having their factories there. Coimbatore region is also developing into an auto component cluster.

Truck and Bus Body Building Industry Clusters

The Namakkal- Tiruchengode belt in western Tamil Nadu is known for its truck body building industry. About 150 of the 250 units in this sector are located in this cluster including 12 large-sized body building houses. Karur is another major hub with more than 50 units. Many entrepreuners were previous employees in a big firm involved in body building who came out to set up their own units.

Textile Clusters

Tamil Nadu is home to the largest textiles sector in the country. Because of the development of cotton textile industry since the colonial period, Coimbatore often referred as the “Manchester of South India”. At present, most of the spinning mills have moved to the smaller towns and villages  at a radius over 100 to 150 km around the Coimbatore city.Tamil Nadu is the biggest producer of cotton yarn in the country.

Palladam and Somanur,small towns near Coimbatore and the villages near these towns, are home to a dynamic powerloom weaving cluster as well. Powerloom is however more widespread with Erode and Salem region too having a large number of power loom units.

Tiruppur is famous for clustering of a large number of firms producing cotton knitwear. It accounts for nearly 80% of the country’s cotton knitwear exports and generates employment in the range of over three lakh people since the late 1980s. It is also a major producer for the domestic

market. Because of its success in the global market, it is seen as one of the most dynamic clusters in the Global South. While initially most firms were run by local entrepreneurs, at present, some of the leading garment exporters in India have set up factories here.

Apart from body building, Karur is a major centre of exports of home furnishings like table cloth, curtains, bed covers and towels. Bhavani and Kumrapalayam are again major centres of production of carpets, both for the domestic and the global markets. Apart from such modern clusters, there are also traditional artisanal clusters such as Madurai and Kanchipuram that are famous for silk and cotton handloom sarees. Even these clusters have witnessed a degree of modernisation with use of powerlooms in several units.

Leather and Leather Goods Clusters

Tamil Nadu accounts for 60 per cent of leather tanning capacity in India and 38 per cent of all leather footwear, garments and components. Hundreds of leather and tannery facilities are located around Vellore and its nearby towns, such as Ranipet, Ambur and Vaniyambadi. The Vellore district is the top exporter of finished leather goods in the country. Chennai also has a large number of leather product making units involved in exports. There is another clustering of leather processing in Dindigul and Erode. The leather products sector too is a major employment generator.

Fireworks, Matches and Printing Cluster

Sivakasi region, once famous for its match industry has now become a major centre for printing and fireworks in the country.It is believed to contribute to 90% of India’s fireworks production, 80% of safety matches and 60% of offset printing solutions. The offset printing industry has a high   degree   of   specialisation  among   firms   with   several   of   them undertaking just one operation required for printing. All these industries have their origin in the colonial period and at present offer employment to a large number of workers.

Electronics and Information Technology (IT) Clusters

After the economic reforms started inthe early 1990s, the state has seen the entry of hardware and electronics manufacturers like Nokia, Foxconn, Motorola, Sony-Ericsson, Samsung and Dell making cellular handset devices, circuit boards and consumer electronics. They have all been set up in the Chennai region. While Nokia has been closed down,

Chennai  still  continues  to  be  a  minor  electronics  hub  in  the  country. 

Similarly, with the expansion of the software sector, Chennai and, to a limited extent Coimbatore, have emerged as centres for software services. Information Technology Specific Special Economic Zones :

In order to make development more inclusive, Tier II cities such as Coimbatore,Madurai, Trichy, Tirunelveli, Hosur and Salem have been promoted as IT investment destinations apart from the Chennai region.

To facilitate this, ELCOT has established ELCOSEZs (IT Specific Special Economic Zones) in the following eight locations:

  • Chennai – Sholinganallur
  • Coimbatore – Vilankurichi
  • Madurai – Ilandhaikulam
  • Madurai – Vadapalanji-Kinnimangalam
  • Trichy – Navalpattu

Companies desiring to set up units in the state can avail themselves of the facilities provided in ELCOSEZs. The possibility of setting up ELCOSEZs in new locations will be explored based on demand and viability.

The Policy Factors that Helped the Industrialisation Process in Tamil Nadu

Policy factors can be divided into three aspects:


Industries require skilled human resources.Apart from a lot of attention to primary education to promote literacy and basic arithmetic skills, the state is known for its vast supply of technical human resources. It is home to one of the largest number of engineering colleges, polytechnics and Industrial Training Centres in the country.


The widespread diffusion of electrification has contributed to the spread of industrialization to smaller towns and villages in the state. Along with electrification, Tamil Nadu is known for its excellent transport infrastructure, especially minor roads that connect rural parts of the state

to nearby towns and cities. A combination of public and private transport

has also facilitated rural to urban connectivity and therefore connect

small producers to markets better.

Industrial Promotion

Apart   from   investments   in   education   and   transport   and   energy infrastructure, active policy efforts were made to promote specific sectors and also industrialisation in specific regions. Policies to promote specific sectors like automobile, auto components, bio technology and Information and communication Technology sectors have been formulated in the post reform period. In addition, the state has put in place several industrial promotion agencies for both large enterprises and the small and medium segments, as well as to provide supporting infrastructure.


The following are some agencies that have played a key role in industrialization in the state

SIPCOT (State Industries Promotion Corporation of Tamil Nadu), 1971

SIPCOT was formed in the year 1971 to promote industrial growth in the state by setting up industrial estates.

TANSIDCO (Tamil Nadu Small Industries Development Corporation), 1970

TANSIDCO is a state-agency of the state of Tamil Nadu established in the year 1970 to promote small-scale industries in the state. It gives subsidies and provide technical assistance for new firms in the small scale sector.

TIDCO (Tamil Nadu Industrial Development Corporation), 1965

TIDCO is another government agency to promote industries in the state and to establish industrial estates.

TIIC (Tamil Nadu Industrial Investment Corporation Ltd.), 1949

TIIC is intended to provide low-cost financial support for both setting up new units and also for expansion of existing units. Though it is meant to meet the requirements of all types of firms, 90% of support goes to micro, small and medium enterprises.

TANSI (Tamil Nadu Small Industries Corporation Ltd.), 1965

TANSI was formed in 1965 to take over the small scale-units that were set up and run by the Department of Industries and Commerce. It is supposed to be the first industrial corporation operating in the domain for small enterprises.

Special Economic Zones (SEZs)

A policy was introduced on in April 2000 for the settling up of special Economic Zones in the country with a view to a hassle-free environment for exports. Units may be set up in SEZ units are on a self-certification basis. The policy provides for setting up of SEZs in the public, private,joint sector or by state governments. It is also envisaged the some of the existing Export Processing Zones, would be converted in to Special Economic Zones.

Accordingly, the government has converted Export Processing Zones located at following places.

Nanguneri SEZ – A multi product SEZ, Thirunelveli Ennore SEZ – Thermal power project, Vayalur Coimbatore SEZ – IT Parks

Hosur SEZ – Auto Engineering, Electronics, Defence and Aerospace Perambalur SEZ – Multi product SEZ

Autocity SEZ – Automobile/Auto Components, Tiruvallur

India-Singapore SEZ – IT & ITES, Electronic Hardware, Logistics and Warehousing –Thiruvallur District

Bio-Pharmaceuticals   SEZ   –   Clinical   Research   Organisation,   Poison Control Centre, Centre for Regenerative Medicine, Medicine Research Madras Export Processing Zone (MEPZ)

MEPZ is a Special Economic Zone in Chennai. It is one of the seven export processing zones in the country set up the central government. It was established in 1984 to promote foreign direct investment, enhance foreign exchange earnings and create greater employment opportunities in the region. The MPEZ headquarters is located on GST Road in Tambaram, Chennai.

Emerging Services Sector in Tamil Nadu

With technological changes, industries too are not able to absorb labour. Automation has been reducing the need for labour in manufacturing. The services sector has emerged as a much bigger employer over the last three decades. Tamil Nadu has become a hub for some important and dynamic service sectors such as software services, healthcare and education services. Healthcare and educational services are diffused across major cities, Chennai and Coimbatore in particular.Software  services  is,  however,  largely  confined  to   Chennai.

Only in the last ten years, a few software firms have moved to Coimbatore.

Issues with Industrialisation

Though Tamil Nadu has emerged as a relatively highly industrialised state in the country, the state faces a few issues in sustaining the process.
