Question

Read the passage and answer the question. Passage: In the dry district of Alwar in Rajasthan, the village of Bhanwta once faced the same crisis every summer: its wells ran dry, its fields cracked, and young men left for the cities in search of work. Then, in the mid-1980s, the villagers began to revive an old idea. With the help of a local voluntary organisation, they rebuilt johads, small earthen dams that catch rainwater and let it sink slowly into the ground. The work was done by the villagers themselves, each family contributing labour and a share of the cost. Within a few years the water table began to rise. Wells that had been dry for a decade filled again, and farmers who had grown only one rain-fed crop a year began to grow two. The revival also changed the village in quieter ways: women no longer walked miles to fetch water, and the young men who had left began to return. Today Bhanwta is studied by water experts from many countries, yet the villagers themselves describe the change simply: they stopped letting the rain run away. What happened within a few years of rebuilding the johads?
