Suppose you visit your native village after about 10 years. The village lies in a semi-
arid region and receives rainfall of 500 mm. Traditionally in the farming village, the
villagers used to practice mixed cropping of sorghum, pearl millet, pigeon pea,
chickpea, and groundnut. But over the last 15 years, they have shifted to paddy (rice)
cultivation in over 90% of the farming land. There are three small lakesin the village,
but the farmers rely on tube-wells for irrigation. When you took a tour of the village,
you found that two of the lakes have dried up while the surface of the third lake is
covered with an overgrowth of algae.
A. Explain the reasons for the condition of the three lakes. Also, suggest
measures that the villagers need to adopt to restore these wetlands to their
original condition.
B. If the above situations persist for few more years, what will be the condition
of groundwater, explain?
