Infrastructure: Engine of India’s Development Class 7 Source/Case Based Questions

1. Read the following extract and answer the questions that follow:

Highways cannot be built everywhere especially in difficult terrains like , dense forests, wide river beds, and steep mountains. In such cases, bridges and tunnels enable ease of access. For instance, the Dhola Sadiya Bridge (or the Bhupen Hazarika Setu) connects Assam and Arunachal Pradesh across the Lohit River, a tributary of the Brahmaputra. At 9.15 km, it is the second longest bridge in India. Before it was built, people had to rely on ferries for travel, which did not work during floods. Now, the bridge provides year-round travel and has cut travel time by four hours. Farmers can take their vegetables and fruits to the market before they spoil, and people can access hospitals or medicines faster, even during floods.

Another infrastructure marvel closer to nature is the Meghalaya’s living root bridges which are crafted by the indigeneous Khasi and Jaintia tribes using the roots of the Ficus elastica tree or the Indian rubber tree. They guide the roots across streams with bamboo and palm trunks, and over many years the roots grow stronger, twisting into natural bridges. Some take decades or even centuries to mature and can last for hundreds of years, standing 15-30 m high. These bridges are not just pathways but living and growing structures which have been nurtured over generations.

Taking care of public infrastructure is a collective responsibility.

We also need to improve Panchayat and municipal administrative services for waste management, sewer systems, traffic management, provision of clean and safe drinking water, pedestrian- friendly footpaths. In addition, we need safe and sustainable infrastructure that uses cleaner energy and environment-friendly materials to minimise pollution and harm to bio-diversity — for instance, using solar panels for generating electricity for the buildings can reduce emissions. The design of the infrastructure should consider the needs of children, the elderly and disabled persons.
