Answer: (A) 1 and 2 only

Correct Answer: (a) Donyi Polo Airport and Kushinagar International Airport (1 and 2 only).

Both Donyi Polo (Hollongi, Arunachal Pradesh) and Kushinagar (Uttar Pradesh) were built as Greenfield projects — meaning they were built from scratch on new sites, not by upgrading existing airports.

Vijayawada International Airport is NOT a Greenfield project — it was an expansion/upgrade of an existing airport.

Key concept:

  • Greenfield = built on a completely new site.
  • Brownfield = upgrade of existing infrastructure.

India's Greenfield Airports Policy (2008) governs how new airports are approved.

Why this was asked

Donyi Polo Airport in Arunachal Pradesh opened in 2022 as India's newest Greenfield airport, while Kushinagar International Airport became operational in 2021 with the first international flight carrying Buddhist pilgrims.

The government has been actively promoting Greenfield airports under the UDAN scheme and National Infrastructure Pipeline to improve connectivity in underserved regions.

The question tests whether students can distinguish between Greenfield projects (built from scratch) versus Brownfield projects (upgrades of existing infrastructure).

Indian Economy Greenfield projects airports

Greenfield vs Brownfield Airport Projects: Key Distinctions

Must know

Greenfield airports are built from scratch on completely new sites

Brownfield airports involve upgrading or expanding existing airport infrastructure

Good to know

India's Greenfield Airports Policy (2008) governs approval of new airports

Most greenfield airports use PPP (Public-Private Partnership) model

Airport development in India follows two distinct approaches. Greenfield projects start with virgin land and build entirely new aviation infrastructure, while brownfield projects work with existing airports to enhance capacity or facilities.

Operational Impact

May disrupt current operations

The Greenfield Airports Policy of 2008 established guidelines for developing new airports in India. It allows 100% FDI in greenfield projects and mandates that new airports must be at least 150 km away from existing ones (unless in metro cities with congested airports).

Exam traps

Trap: Vijayawada International Airport sounds 'international' but it's not a greenfield project - it was upgraded from existing infrastructure

Confusion: Don't assume all 'new' or 'international' airports are greenfield - check if they were built on virgin land

Mix-up: Students often confuse greenfield (new site) with green energy or environmental projects

Donyi Polo Airport

Indian Economy Donyi Polo Airport

Donyi Polo Airport: Arunachal Pradesh's Greenfield Project

Must know

Located in Hollongi, Arunachal Pradesh - built as greenfield project

Strategically important for Northeast connectivity and border security

Good to know

Named after Donyi Polo (Sun-Moon worship) of indigenous Arunachali tribes

Donyi Polo Airport at Hollongi represents a major infrastructure milestone for Arunachal Pradesh. Built entirely on new land, it serves as the state's first major commercial airport and significantly improves connectivity to India's northeastern frontier.

Strategic Significance

Border connectivity: Enhances civilian and military access near India-China border

Tourism boost: Opens Arunachal Pradesh's remote areas to greater tourist access

Economic development: Facilitates trade and investment in the northeastern state

Emergency operations: Provides critical infrastructure for disaster relief and medical emergencies

Location Context

Donyi Polo Airport serves as Arunachal Pradesh's gateway, strategically positioned near the capital Itanagar

Kushinagar International Airport

Indian Economy Kushinagar International Airport

Kushinagar International Airport: Buddhist Circuit Gateway

Must know

Built as greenfield project in Kushinagar, Uttar Pradesh

Serves the Buddhist Circuit - Kushinagar is where Buddha attained Mahaparinirvana

Good to know

Connects international Buddhist pilgrims, especially from Sri Lanka and Southeast Asia

Kushinagar International Airport was built from scratch to serve one of Buddhism's most sacred sites. As a greenfield project, it provides direct international connectivity to the place where Buddha achieved Mahaparinirvana (final liberation).

Religious & Economic Impact

Buddhist pilgrimage hub: Direct access for international Buddhist devotees to Kushinagar

Tourism revenue: Boosts religious tourism economy in eastern Uttar Pradesh

Regional development: Catalyzes infrastructure growth in economically backward areas

International relations: Strengthens India's ties with Buddhist-majority countries

Buddhist Circuit Context

Kushinagar Airport serves the eastern anchor of India's Buddhist Circuit pilgrimage route

Vijayawada International Airport

Indian Economy Vijayawada International Airport

Vijayawada International Airport: Brownfield Expansion Project

Must know

NOT a greenfield project - it's a brownfield expansion of existing airport

Located in Vijayawada, Andhra Pradesh - upgraded existing facilities to international standards

Good to know

Serves as commercial hub for Andhra Pradesh after state bifurcation

Vijayawada International Airport represents a brownfield development - upgrading and expanding pre-existing airport infrastructure rather than building on virgin land. This makes it fundamentally different from true greenfield projects.

Development Approach

Existing base: Built upon previous airport facilities and runway infrastructure

International upgrade: Enhanced terminals and services to handle international flights

Cost efficiency: Lower investment compared to building entirely new airport

Operational continuity: Maintained domestic services during expansion phases

Exam traps

Major trap: The word 'International' in the name doesn't mean it's greenfield - Vijayawada was upgraded, not built new

UPSC trick: Questions often include airports with 'International' in their names to test greenfield vs brownfield understanding
