The construction of large dams leads to some problems.
People close to the source grow water-intensive crops like sugarcane and rice whereas people farther downstream do not get sufficient water to grow these crops. This causes social problems resulting due to unequal distribution of water. Other problems related to the construction of dams are economic and environmental problems.

Question 7.
A diagram of traditional water harvesting system is given below:
The statement which defines the system and its parts is:
(a) This is an ideal setting of the Khadin system and A = Catchment area; B = Saline area and C = Shallow dug well:
(b) This is an ideal setting of the Shallow dug well system and A = Catchment area; B = Saline area and C = Khadin.
(c) This is an ideal setting of Catchment area and A = Khadin, B = Saline area, and C = Shallow dug well.
(d) This is showing the Saline area and A = Catchment area; B = Khadin and C = Shallow dug well.
Answer:
(a) This is an ideal setting of the Khadin system and:
A = catchment area
B = Saline area
C = Shallow dug well
Explanation: Khadin is a traditional rainwater haversting system in Rajasthan. The main feature of Khadin system of rainwater harvesting is a very long earthen embankment called ‘bund’ built across the lower edge of the sloping farmland. The rainwater from catchment area flows down the slopes and stopped by the bund to form a reservoir the excess water flows through pathwalls (made for this purpose) and filLs the shallow well dug behind the bund. This area is subsequently used for growing crops.
