Regional Planning

Nature and Scope of Regional Planning

Regional planning is the deliberate process of guiding the spatial organisation of economic activities, infrastructure, settlements, and land use across a subnational territory larger than a single city or local authority but smaller than the nation as a whole. It occupies the middle ground between national economic planning (which sets macro targets for growth, investment, and sectoral priorities) and local urban planning (which regulates land use, building standards, and neighbourhood services within municipal boundaries). Regional planning asks which activities should be located where within a nation's territory, how the benefits of economic growth can be spread more evenly across space, how infrastructure networks should be laid out to connect places and reduce spatial frictions, and how environmental resources can be managed at the watershed, ecosystem, or river-basin scale that transcends local administrative boundaries.

The term region in planning is used in several overlapping senses. The formal or administrative region is delimited by government for purposes of planning and governance: India's states, the planning zones of the National Capital Region, the river basin areas of the Damodar Valley Corporation. The functional or nodal region is defined by actual patterns of economic interaction, commuting, or trade, centred on a metropolitan node and its hinterland. The homogeneous region is defined by uniformity of some characteristic: the arid zone, the tribal belt, the hill districts eligible for special development support. Each concept of region leads to different planning instruments and institutional arrangements.

Regional planning as a formal discipline emerged in the early twentieth century at the confluence of several intellectual and political currents: the garden city movement of Ebenezer Howard, the regional survey tradition of Patrick Geddes, the Tennessee Valley Authority as a model of integrated river-basin development in the United States, and the post-World War II welfare state commitment to spatial equity and balanced development in Britain and western Europe. In postcolonial developing countries including India, regional planning was shaped additionally by the Five Year Plan framework, the socialist commitment to reducing spatial disparities, and the need to integrate diverse regions into a national development project.

Concept of Region: Types and Delimitation

The delimitation of regions for planning purposes involves choices about criteria, methods, and scale. Single-feature regions are delimited on the basis of one criterion such as rainfall, soil type, language, or tribal population. Multi-feature or composite regions are delimited on the basis of several overlapping criteria simultaneously, using statistical techniques such as cluster analysis, principal components analysis, or factor analysis to identify groups of spatially contiguous units that are internally similar on multiple dimensions.

Planning regions in India have been delimited at several scales. At the national level, the National Development Council and the erstwhile Planning Commission recognised broad agro-climatic zones (the National Agricultural Research Project identified 15 agro-climatic zones for agricultural research and development planning). At the river-basin level, river basin organisations such as the Damodar Valley Corporation (DVC), the Bhakra-Beas Management Board, and the Tungabhadra Board manage multipurpose water resources across state boundaries. At the metropolitan level, metropolitan planning committees are mandated under the 74th Constitutional Amendment for cities with populations above one million, and the National Capital Region Planning Board manages the NCR as a functional planning region covering parts of Delhi, Haryana, Uttar Pradesh, and Rajasthan. At the district level, the District Planning Committee (DPC) under Article 243ZD of the Constitution is the constitutionally mandated planning body at the district scale.

Theoretical Approaches to Regional Development

Several theoretical frameworks have shaped the understanding of regional economic development and the rationale for regional planning interventions.

Neoclassical convergence theory, associated with the work of Solow and Swan and extended to regions by Borts and Stein, predicted that market forces would automatically reduce spatial inequalities over time. If capital earns higher returns in poor (capital-scarce) regions, investment will flow from rich to poor regions; if wages are lower in poor regions, labour will migrate to rich regions or firms will relocate to exploit the labour cost advantage. Either way, factor prices and income levels should converge between regions over time. The empirical evidence on regional convergence is mixed: some studies find conditional convergence (regions converge controlling for structural differences), others find divergence or club convergence (rich regions converge to one equilibrium, poor regions to another).

Cumulative causation theory, proposed by Gunnar Myrdal in Economic Theory and Underdeveloped Regions (1957), offered a diametrically opposed prediction. Myrdal argued that market forces tend to produce cumulative divergence rather than convergence between regions. Successful regions attract further investment (through agglomeration economies, skilled workers, and better infrastructure), while lagging regions lose investment, skilled labour, and multiplier effects to the growing core. Myrdal called these self-reinforcing processes backwash effects. Spread effects, in which growth in the core stimulates demand for raw materials and agricultural products from the periphery and diffuses technology and enterprise outward, exist but are typically weaker than backwash effects in developing countries. The implication is that government policy intervention is necessary to counteract the spatial concentration tendency of market forces.

Growth pole theory, developed by Francois Perroux (1950) and extended spatially by Jacques Boudeville, argued that economic growth does not occur uniformly across space but is concentrated in dynamic propulsive industries or firms that generate strong backward and forward linkages, stimulate technological change, and pull surrounding activities into their orbit of influence. A growth pole in Perroux's original conception was an industry complex (not necessarily a physical place), but Boudeville translated it into a geographic concept: the growth centre or growth pole as a city or urban agglomeration that concentrates propulsive industries and acts as a motor of regional development for its surrounding hinterland. Planning applications of growth pole theory led to the deliberate creation of new industrial cities and growth centres in peripheral regions, with the expectation that the induced backward and forward linkages and the provision of urban services would stimulate development across the surrounding region. The empirical record of growth pole policies has been mixed: some succeeded in industrial concentration at the chosen centres but failed to generate spread effects to the surrounding region, producing enclave growth rather than regional development.

Core-periphery models, articulated by John Friedmann (1966) in Urbanization, Planning, and National Development, described the spatial organisation of development as a hierarchy of cores and peripheries. At each scale (global, national, regional, local), a core region concentrates economic dynamism, innovation, political power, and infrastructure while peripheral regions supply raw materials and labour. Friedmann identified four stages of spatial development: the pre-industrial stage with isolated local centres; the early industrial stage with a single dominant core and periphery; the mature industrial stage with a core and peripheral sub-systems; and the post-industrial stage with a functionally interdependent network of urban centres. Development policy in this framework must aim to reduce core-periphery disparities through deliberate decentralisation of industry and investment to peripheral regions, development of growth poles in backward regions, and improvement of infrastructure connectivity between cores and peripheries.

Dependency theory, from the Latin American structuralist tradition (ECLAC, Prebisch, Frank), interpreted regional underdevelopment as the product of unequal exchange between cores and peripheries, both internationally and nationally. The internal colonies framework applied dependency logic to subnational regions: the tribal belts of India's central and northeastern regions, the dryland Deccan, and the hill states have been described as internal peripheries that supply raw materials (minerals, forest products, cheap labour) to the industrial core but receive little in return in terms of wages, infrastructure, or value addition. The solution in this framework is not simply better integration with the national economy but a restructuring of the terms of exchange and a shift of control over resources to peripheral communities.

Regional Imbalances and Disparities in India

India exhibits profound and persistent regional economic disparities. At the state level, per capita income in the richest states (Goa, Telangana, Haryana, Karnataka, Maharashtra) is four to six times higher than in the poorest (Bihar, Uttar Pradesh, Jharkhand, Madhya Pradesh). The BIMARU acronym, coined by demographer Ashish Bose to describe Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh as states with high birth rates and indicators of demographic underdevelopment, captures a broadly recognised regional divide between the more developed states of southern, western, and north-western India and the less developed states of the Hindi heartland, eastern India, and the northeast.

The sources of regional disparities in India include: colonial patterns of investment concentration in port cities and railway corridors; post-independence public investment in large dams, steel plants, and defence industries that did not always target the most backward regions; the Green Revolution's concentration of benefits in irrigated wheat-growing areas (Punjab, Haryana, western UP); the geography of natural resources (mineral-rich states like Jharkhand and Odisha remain paradoxically underdeveloped due to the enclave character of mining, weak linkages to local industry, and the displacement of tribal communities); and the geography of educational and health infrastructure that both reflects and reproduces regional inequalities.

Regional disparities in India are measured by multiple indicators: state per capita net domestic product (NDP), human development index scores, poverty headcount ratios, infant mortality rates, female literacy rates, and access to infrastructure (roads, electricity, safe water, sanitation). The Planning Commission's Backward Regions Grant Fund (BRGF), the Backward Districts Initiative under the Rashtriya Sam Vikas Yojana, and the Ministry of Development of North Eastern Region (DoNER) represent central government efforts to target investment to the most backward districts and regions. The Niti Aayog's Aspirational Districts Programme (ADP, 2018), covering 117 of India's most backward districts, is the current flagship programme targeting convergent delivery of basic services and development outcomes in the least developed districts.

River Basin Planning

River basin planning treats the river basin as the fundamental unit for integrated management of water, land, and related resources. The river basin is a natural region defined by hydrology: all land draining to a common outlet, bounded by watershed divides. The river basin approach recognises that water management decisions upstream affect downstream users and ecosystems, that floodplain management, watershed conservation, and water allocation are interdependent, and that the river basin is the appropriate scale for resolving competing demands among users in agriculture, industry, domestic supply, navigation, fisheries, and ecosystem services.

The Tennessee Valley Authority (TVA), established in 1933 as part of Roosevelt's New Deal, was the most influential global model of integrated river basin development. The TVA built a series of dams on the Tennessee River and its tributaries for flood control, hydroelectric power generation, navigation improvement, and fertiliser production, while simultaneously undertaking reforestation, soil conservation, malaria control, and rural electrification across a seven-state region that had been among the most economically depressed in the United States. The TVA became a global template: India's Damodar Valley Corporation (DVC), established in 1948 and modelled explicitly on the TVA, was intended to provide similar multipurpose development of the Damodar River basin across Bihar and West Bengal (now Jharkhand and West Bengal), addressing the basin's history of catastrophic floods (the Damodar was called the Sorrow of Bengal), coal-powered industrialisation, and rural poverty. The DVC built a system of dams (Tilaiya, Konar, Maithon, Panchet) and a thermal power complex, but fell short of the TVA's integrated rural development mission, functioning primarily as a power utility rather than a comprehensive regional development agency.

Other major river basin development projects in India include the Bhakra-Nangal project on the Sutlej (Punjab/Himachal Pradesh, irrigation and hydropower), the Hirakud project on the Mahanadi (Odisha, the longest earthen dam in Asia), the Nagarjunasagar and Srisailam projects on the Krishna (Telangana/Andhra Pradesh), and the Sardar Sarovar project on the Narmada (Gujarat), the last being the most contested due to large-scale displacement of tribal and other communities without adequate resettlement, which generated the Narmada Bachao Andolan led by Medha Patkar and sparked a major national debate on the social and environmental costs of large dams.

The World Commission on Dams (2000), co-chaired by Kader Asmal, published a landmark report critically evaluating the global record of large dams and recommending a rights-based framework for future dam development that prioritised consent of affected communities, comprehensive options assessment, and equitable sharing of benefits. The report significantly shifted the international discourse on large dam projects, though its recommendations have been only partially implemented in India and other developing countries.

Integrated watershed management at smaller scales (micro-watershed or sub-watershed of a few hundred to a few thousand hectares) is a major instrument of dryland agricultural development and soil and water conservation in India. The Watershed Development Component of the Pradhan Mantri Krishi Sinchai Yojana (PMKSY-WDC, integrating earlier programmes including IWDP, DPAP, and DDP) funds watershed treatment works including check dams, bunding, vegetative cover, and recharge structures across dryland districts. Watershed programmes in semi-arid Rajasthan, Gujarat, Maharashtra, Karnataka, and Andhra Pradesh have demonstrated significant potential for groundwater recharge, reduction of runoff and soil erosion, and improvement of agricultural productivity in rainfed farming systems.

Planning for Backward Regions and Special Area Development

The identification and targeting of backward or underdeveloped regions for special development attention has been a persistent theme of Indian planning since the Second Five Year Plan (1956-61). The concept of backwardness is multidimensional, encompassing low per capita income, poor infrastructure, low agricultural productivity, limited industrial development, high poverty, poor human development indicators, and in many cases a preponderance of scheduled caste (SC) and scheduled tribe (ST) populations who have historically been marginalised from mainstream development.

The Fifth Five Year Plan (1974-79) introduced the Hill Area Development Programme (HADP) and the Tribal Sub-Plan (TSP) as special area programmes. The Tribal Sub-Plan, renamed the Scheduled Tribe Component (STC) more recently, mandates that funds from all central ministries be allocated proportionally to tribal areas in line with the tribal share of the national population (approximately 8.6 percent), to ensure that tribal communities receive their fair share of development benefits. The implementation of TSP/STC has been criticised for diversion of funds to non-tribal purposes and for the dominance of infrastructure over livelihood-oriented programmes.

Special category states in India's federal fiscal architecture received special plan assistance from the erstwhile Planning Commission and now receive a higher share of central assistance through the National Development Council and Finance Commission. The original special category states (Assam, Nagaland, Himachal Pradesh, Jammu and Kashmir, and later others including all northeastern states, Uttarakhand, and Sikkim) were recognised as states with difficult terrain, low population density, significant tribal population, strategic border location, or economic non-viability requiring additional central support. The 14th Finance Commission (2015-20) abolished the special category status and replaced it with a significantly enhanced tax devolution to all states (from 32 to 42 percent of the divisible pool), with the argument that higher unconditional transfers better respected states' fiscal autonomy than conditional special category grants.

Desert development in India targets the Thar Desert and allied arid zones of Rajasthan, Gujarat, and Haryana through the Desert Development Programme (DDP, absorbed into PMKSY-WDC) and the Indira Gandhi Nahar Pariyojana (IGNP), the world's longest canal system, bringing Himalayan waters from the Harike Barrage in Punjab to the Thar Desert and transforming large areas of desert into irrigated farmland, enabling wheat and cotton cultivation and the settlement of colonists from more densely populated areas. The IGNP has been celebrated for agricultural development and criticised for waterlogging and salinisation in command areas, disruption of pastoral Rajput and Muslim communities, and ecological damage to the desert ecosystem.

Hill area development in India addresses the specific challenges of Himalayan, sub-Himalayan, and peninsular hill districts: difficult terrain increasing the cost of infrastructure provision, fragile mountain ecosystems vulnerable to deforestation, landslides, and erosion, limited flat arable land restricting agricultural productivity, isolation from market networks, and outmigration of youth. The North Eastern Council (NEC), established in 1971, coordinates regional planning for the eight northeastern states (Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, and Tripura), which face the additional challenges of ethnic diversity and conflict, international borders with multiple countries, and the strategic security imperatives of the Chicken's Neck corridor (Siliguri corridor, the narrow strip connecting the northeast to the rest of India).

Multi-Level Planning in India

India's planning system operated at multiple spatial scales simultaneously. At the national level, Five Year Plans (1951-2017) set macroeconomic targets and priorities for the national economy. At the state level, state plans allocated resources across sectors and districts. At the district level, the District Plan (integrated rural and urban development for the district) was mandated but weakly institutionalised in most states. At the sub-district level, the block (tehsil/taluka) is the unit for many rural development programmes. At the village level, the gram panchayat plan (Gram Panchayat Development Plan or GPDP) is now mandated under the Rashtriya Gram Swaraj Abhiyan.

The 73rd and 74th Constitutional Amendments (1992) created a constitutional mandate for decentralised planning through elected bodies at the village (gram panchayat), block (panchayat samiti), and district (zila parishad) levels in rural areas, and through municipal bodies (nagar panchayats, municipal councils, and municipal corporations) in urban areas. Schedule 11 of the Constitution lists 29 subjects to be transferred to panchayats, including agriculture, land improvement, minor irrigation, social forestry, rural housing, drinking water, and maintenance of community assets. Schedule 12 lists 18 subjects for municipal bodies. In practice, devolution has varied greatly across states, with Kerala, Karnataka, West Bengal, and a few others having substantially devolved functions, funds, and functionaries, while most states have retained control at the state level.

The District Planning Committee (DPC) under Article 243ZD of the Constitution is constituted to prepare a draft development plan for the district, integrating the plans prepared by panchayats and municipalities within the district. The DPC is intended to ensure that district-level planning reflects the felt needs of local communities rather than being imposed from above. In practice, DPCs are not constituted in all states and function weakly where they exist, with most districts continuing to receive planning inputs through vertical line department programmes rather than genuine district-level integration.

The abolition of the Planning Commission in 2014 and its replacement by the Niti Aayog (National Institution for Transforming India) marked a shift from centralised indicative planning with allocative authority over state plan funds to a more advisory, competitive, and advocacy-based model. The Niti Aayog does not have financial transfer authority; central funds flow to states through Finance Commission devolution and centrally sponsored schemes (CSS). The Niti Aayog's key spatial initiatives include the Aspirational Districts Programme (2018), the district-level development index, and various competitive federalism frameworks that rank states and districts on development indicators to create incentives for improvement.

Industrial Location Policy and Regional Development

Industrial location policy is a central instrument of regional planning, since the location of industries determines employment, income, and multiplier effects in regional economies. The post-independence period saw the Indian government use licensing and regulation (under the Industries Development and Regulation Act, 1951) to steer industry away from already-congested metropolitan areas and towards backward regions and states. The Location Policy under industrial licensing required entrepreneurs to seek government approval for plant location, with approvals conditional on backward area siting in many cases.

Industrial estates and growth centres were established by state governments and central agencies in backward districts to provide serviced land, power, water, and roads to attract footloose industries. The Industrial Development Bank of India (IDBI), the Small Industries Development Bank of India (SIDBI), and state industrial finance corporations provided subsidised credit for industries in backward areas. Transport subsidies, tax holidays, and capital investment subsidies were offered to attract industry to designated backward areas. The effectiveness of these policies was limited: many industries preferred established locations with better infrastructure, skilled labour, and market access despite the subsidies, and others set up nominal units in backward areas to capture subsidies while maintaining effective operations near metropolitan centres.

Post-liberalisation (after 1991), industrial location policy shifted from directive licensing to incentive-based approaches. The Special Economic Zone (SEZ) policy (formalised under the SEZ Act 2005) created zones with world-class infrastructure and tax exemptions to attract export-oriented industry and foreign investment. SEZs in India are concentrated in states with better infrastructure and coastal access (Maharashtra, Gujarat, Tamil Nadu, Andhra Pradesh, Karnataka, Rajasthan), and critics argue they have exacerbated rather than reduced regional disparities by concentrating investment in already-developed coastal and semi-coastal regions. The National Industrial Corridor Development Programme plans a series of industrial corridors linking major cities with high-speed freight transport: the Delhi-Mumbai Industrial Corridor (DMIC), the Chennai-Bengaluru Industrial Corridor (CBIC), the Amritsar-Kolkata Industrial Corridor (AKIC), the East Coast Economic Corridor (ECEC) along the Vizag-Chennai coast, and the Bengaluru-Mumbai Economic Corridor (BMEC). These corridors are intended to catalyse manufacturing and logistics investment in their influence zones, though progress has been uneven.

Planning for Metropolitan Regions

The rapid growth of Indian metropolitan areas has generated a specific set of regional planning challenges: managing urban sprawl and periurban development, coordinating land use and infrastructure across multiple local authorities within the metropolitan area, providing metropolitan-scale transport (metro rail, ring roads, bus rapid transit), managing metropolitan water supply and sanitation systems, and protecting ecologically sensitive areas within and around the metropolis.

Metropolitan regional planning in India operates through several institutional arrangements. The National Capital Region (NCR) Planning Board, established under the NCR Planning Board Act 1985, covers the territory of Delhi and the NCR extending across parts of Haryana (Gurugram, Faridabad, Sonipat, Panipat), Uttar Pradesh (Meerut, Ghaziabad, Bulandshahr, Hapur), and Rajasthan (Alwar). The NCR Planning Board prepares and periodically revises the Regional Plan for the NCR, which allocates urban development to counter-magnet towns (Meerut, Panipat, Alwar, Mathura-Agra) to reduce pressure on Delhi. The Mumbai Metropolitan Region Development Authority (MMRDA) and similar authorities in Chennai (CMDA), Bengaluru (BDA and BMRDA), Hyderabad (HMDA), and Kolkata (KMDA) plan and develop infrastructure for their respective metropolitan regions, though coordination with municipal corporations and state agencies remains a persistent challenge.

The 74th Constitutional Amendment mandated the constitution of Metropolitan Planning Committees (MPCs) for all cities with populations above one million, to prepare a development plan for the metropolitan area integrating plans of local bodies and ensuring coordination between urban and rural local bodies. In practice, MPCs have been constituted in only a few states (Kerala is a partial exception) and remain largely non-functional in most, with metropolitan planning functions continuing to be exercised by state-level development authorities and line departments rather than through the constitutionally intended decentralised metropolitan governance framework.

Environmental and Sustainable Regional Planning

Regional planning increasingly incorporates environmental sustainability as a core objective, recognising that economic development patterns have spatial environmental consequences that transcend local boundaries. River basin pollution (the pollution of the Ganga, Yamuna, Cauvery, and other major rivers by industrial effluents and urban sewage from multiple cities and industries across a river basin) requires river-basin-scale planning and governance. The National Mission for Clean Ganga (NMCG, Namami Gange programme, 2014) attempts basin-level coordination of sewage treatment, industrial effluent management, riverfront development, and biodiversity conservation across the Ganga basin covering five states and over 500 million people. Forest conservation and biodiversity planning at landscape and ecosystem scale (Project Tiger, Project Elephant, biosphere reserve programmes) transcends individual protected area boundaries and requires corridor planning across multiple states and land use categories.

Coastal Zone Management Plans (CZMPs), prepared under the Coastal Regulation Zone (CRZ) Notification (most recently revised in 2019), regulate development within specified distances of the high-tide line along India's 7,516 kilometre coastline to protect coastal ecosystems, fishery communities, and shoreline stability. The spatial classification of the coastal zone into CRZ-I (most ecologically sensitive, no development), CRZ-II (urbanised coastal areas, regulated development), CRZ-III (rural coastal areas, limited development), and CRZ-IV (water areas including tidal water bodies) creates a spatial planning framework for coastal areas. The Integrated Coastal Zone Management (ICZM) project, supported by the World Bank, has developed CZMPs for several states and introduced modern hazard-line mapping to account for sea-level rise and storm surge risk in coastal zone regulation.

Climate change adaptation and mitigation have become increasingly central to regional and urban planning. The National Action Plan on Climate Change (NAPCC, 2008) identified eight national missions including the National Mission on Sustainable Habitat (urban planning for energy efficiency and waste management), the National Water Mission (integrated water resource management under changing climate), and the National Mission for a Green India (afforestation and ecosystem restoration). State Action Plans on Climate Change (SAPCCs) translate the national framework into state-level spatial strategies. The challenge of integrating climate risk into land use planning (avoiding development in flood plains, coastal erosion zones, and areas of high forest fire risk) is being addressed unevenly across states, with major gaps between planning frameworks on paper and the land use decisions that continue to be made on the ground.

Patrick Geddes and the Regional Survey Approach

Patrick Geddes (1854-1932), the Scottish biologist, sociologist, and town planner, is regarded as a foundational thinker for regional planning. Geddes emphasised that effective planning must be grounded in a thorough survey of the place, including its geological, ecological, historical, economic, and social dimensions, before any plans for intervention are made. His concept of Place-Work-Folk (or Environment-Function-Organism) proposed that any settlement should be understood as the product of the interaction between its physical environment, the work (economic activities) its people perform, and the people themselves with their culture and social organisation. Planning that ignores any of these dimensions is incomplete and likely to produce unintended consequences.

Geddes developed the concept of the Valley Section as a pedagogical device showing how different occupational groups and ways of life (miners, woodsmen, shepherds, farmers, merchants, scholars) are vertically distributed from mountain peaks to coastal plains according to the physical resources available at each altitude, and how any region must be understood in its totality from headwaters to sea. He also coined the term conurbation (1915) for the merged urban agglomeration produced when adjacent cities grow together, and megapolis (anticipating Gottmann's megalopolis concept) for large urban regions. Geddes applied his survey approach in practical planning reports for Indian cities, including reports for Lahore, Delhi, Lucknow, and approximately 50 other cities commissioned by colonial governments, in which he advocated conservative surgery (minimal, respectful intervention in the existing urban fabric) over the destructive bulldozing of historic quarters.

Ebenezer Howard and the Garden City Movement

Ebenezer Howard proposed the garden city concept in To-morrow: A Peaceful Path to Real Reform (1898, revised as Garden Cities of To-morrow in 1902) as a solution to the overcrowding, pollution, and social degradation of industrial cities and the depopulation of the countryside. Howard's Third Magnet diagram presented the garden city as combining the social opportunities and employment of the city with the space, nature, and low rents of the countryside. The planned garden city would be limited in size (approximately 32,000 population) and surrounded by a permanent agricultural greenbelt that would prevent sprawl, provide food, and generate revenue for municipal services. As the city reached its size limit, new garden cities would be built nearby, eventually producing a Social City of interconnected garden cities linked by rapid transport.

Howard's vision was partly realised in the construction of Letchworth (1903) and Welwyn Garden City (1920) in Hertfordshire, England, designed by Barry Parker, Raymond Unwin, and Louis de Soissons. The British New Towns programme, initiated under the New Towns Act 1946 following the Reith Committee recommendations and the Barlow Commission's advocacy of industrial decentralisation from London, created 32 planned new towns across Britain including Harlow, Stevenage, Crawley, Milton Keynes, and the Scottish new towns of East Kilbride and Cumbernauld. These new towns were intended to rehouse overspill population from overcrowded cities, provide planned employment through the attraction of manufacturing industry, and demonstrate that planning could create healthy, mixed, well-serviced urban environments. Their legacy is mixed: some have become thriving centres (Milton Keynes), others have struggled with social deprivation and economic stagnation.

In India, Chandigarh (designed by Le Corbusier and planned from 1950 as the new capital of Punjab after the partition of Lahore to Pakistan), Navi Mumbai (planned from the 1970s as a counter-magnet to Mumbai by CIDCO under the guidance of planners Charles Correa, Pravina Mehta, and Shirish Patel), and Gandhinagar (Gujarat's capital, designed by H.K. Mewada and Prakash Apte on a grid layout), represent the Indian engagement with the planned new town concept. Chandigarh has been criticised for its European modernist planning principles' disconnect from Indian climate, culture, and ways of life, and celebrated for its scale, greenery, and relative livability compared to older Indian cities.

Regional Planning for Infrastructure and Connectivity

Infrastructure connectivity (roads, railways, power, telecommunications, ports, airports) is fundamental to regional development because it determines the transactions costs of moving goods, services, people, and information across space, and hence the viability of economic activities in any location. Poor infrastructure connectivity condemns peripheral regions to high costs of market access, limits the scale of markets reachable by local producers, and discourages private investment. Infrastructure-led regional development is the dominant approach in Indian regional planning today, exemplified by the Bharatmala Pariyojana (national highway development targeting border and coastal connectivity, ring roads, and economic corridor development), the Sagarmala Programme (port-led coastal development and hinterland connectivity), PM Gati Shakti (National Master Plan for Multimodal Connectivity, launched 2021, integrating infrastructure planning across 16 ministries on a GIS-based digital platform), and the National Logistics Policy (2022) aiming to reduce India's logistics costs from approximately 14-16 percent of GDP to 8 percent.

The concept of economic corridors as a spatial planning instrument reflects the insight that development tends to concentrate along transport arteries, and that planned investment in complementary infrastructure (freight logistics, industrial clusters, townships, skills centres) along a high-capacity transport corridor can catalyse industrial and commercial development across a linear zone. The Delhi-Mumbai Industrial Corridor (DMIC), developed with Japanese investment collaboration, plans a series of industrial nodes and smart cities along the 1,500 kilometre Western Dedicated Freight Corridor from Dadri (UP) to Jawaharlal Nehru Port (Mumbai), with the expectation that the freight corridor's reduced transport costs will make industrial production in the corridor nodes economically viable relative to established coastal locations.

Regional Planning in India: Key Milestones and Institutions

India's regional planning history includes several landmark documents and institutions. The Barlow Commission (1940) in Britain and its Indian equivalent, the National Planning Committee of the Indian National Congress (1938, chaired by Nehru), set the political basis for post-independence planning. The First Five Year Plan (1951-56) emphasised river valley development, with the Damodar Valley Corporation, Bhakra-Nangal, and Hirakud as centrepieces. The Second Five Year Plan (1956-61), influenced by the Mahalanobis model, emphasised heavy industrialisation in the public sector, with large integrated steel plants as spatial anchors of regional development (Bhilai in Madhya Pradesh now Chhattisgarh, funded by the Soviet Union; Durgapur in West Bengal, funded by Britain; Rourkela in Odisha, funded by West Germany; and Bokaro in Bihar now Jharkhand, funded by the Soviet Union).

The Gadgil formula for plan assistance allocation, introduced in the Fourth Plan period, attempted to operationalise principles of need (weighting backward states) and equity in the distribution of central plan assistance to states. The Balwantrai Mehta Committee (1957) recommended the Panchayati Raj system for democratic decentralisation of rural development, leading to its adoption in most states in the 1960s though with varying degrees of effectiveness. The Ashok Mehta Committee (1978) reviewed the Panchayati Raj experience and recommended strengthening of the intermediate (block) level. The L.M. Singhvi Committee (1986) proposed constitutional status for panchayats, which was ultimately achieved through the 73rd Constitutional Amendment (1992).

The National Urbanisation Policy (2007) attempted a comprehensive national framework for managing India's urbanisation, recommending strengthening of secondary cities, metropolitanization management, and improved urban governance. The National Urban Policy Framework (2018) and the draft National Urban Policy (2020) updated this framework, emphasising inclusive, resilient, and sustainable urbanisation. The National Spatial Strategy proposed under the Town and Country Planning Organisation (TCPO) aims to provide a national-level spatial framework guiding the distribution of population and economic activity across the country, though a formally adopted national spatial strategy remains elusive in India despite several attempts.

Spatial data infrastructure for regional planning in India has improved significantly with the National Remote Sensing Centre (NRSC) providing satellite imagery, the Survey of India providing topographic mapping, ISRO's Bhuvan geoportal providing open access to spatial data, and the National Informatics Centre (NIC) developing GIS-based planning tools. The SVAMITVA (Survey of Villages and Mapping with Improvised Technology in Village Areas) scheme uses drone-based mapping to create property records in rural India, supporting both property rights formalisation and gram panchayat-level planning. PM Gati Shakti's National Master Plan brings together geospatial data from multiple ministries on a common platform for integrated infrastructure planning, representing the most ambitious effort yet to create a spatial data infrastructure for national and regional planning in India.
