Ports handle most of India's foreign trade; the UDAN scheme (2016) improves regional air connectivity.
Digital India (2015) expands internet access and online government services.

Why infrastructure matters

It lowers the cost of transport and production, attracts industries and creates jobs.
It improves access to health and education, reduces regional inequality and helps during disasters.
Infrastructure must be planned to protect the environment and the rights of people who are displaced.

Important questions with answers

What is infrastructure? Give examples.2 marks

Infrastructure means the basic facilities a country needs to function and grow. Examples include roads, railways, ports and airports (physical), schools and hospitals (social), and telephone and internet networks (digital).

Good roads, railways and ports lower the cost of moving goods and people, so farmers and industries can reach markets easily. Reliable electricity and internet attract new industries and businesses that create jobs. Schools, hospitals and clean water improve people's health and skills, which raises productivity.

Describe the different types of infrastructure in India and explain their importance, including the challenges involved.5 marks

Physical infrastructure includes national highways such as the Golden Quadrilateral, rural roads under the Pradhan Mantri Gram Sadak Yojana (2000), Indian Railways, one of the largest networks in the world, ports that handle most foreign trade, airports supported by the UDAN scheme (2016) for regional connectivity, and power plants and water systems. Social infrastructure includes schools, hospitals, housing and sanitation that improve people's lives. Digital infrastructure includes telephone and internet networks, digital payments and online government services expanded under Digital India (2015). Infrastructure is important because it lowers transport and production costs, links farmers and producers to markets, attracts industries, creates jobs, improves access to health and education, reduces regional inequality and supports relief during disasters. However, projects can harm forests, rivers and wildlife and displace communities, so they must be planned with environmental care, fair compensation and the participation of local people.
