1996-7 and 2002-3, the area under canal irrigation declined by 2.4 million ha (13.8 percent), the area under tank irrigation fell by 1.4 million ha (42.4 percent), and the area irrigate by all other sources declined by 1 million ha (28 percent). The only irrigation source that increased its share was groundwater wells, by 2.8 million ha (more than 9 percent) Why has such a change in irrigation demands happened? 1. Not enough supply of water from canals 2. More tubewell irrigation by farmers in the source areas of rivers 3. High cost of irrigation water, and diversion for non-farm use 4. Joint use of water not possible due to social and economic inequalities

The correct answer is 1 and 4.
-
1996-7 and 2002-3, the area under canal irrigation declined by 2.4 million ha (13.8 percent), the area under tank irrigation fell by 1.4 million ha (42.4 percent), and the area irrigated by all other sources declined by 1 million ha (28 percent).
-
The only irrigation source that increased its share was groundwater wells, by 2.8 million ha (more than 9 percent).
-
This change in irrigation demands happened because:
-
Not enough supply of water from canals.
-
Joint use of water not possible due to social and economic inequalities.
