Answer:

The Indo-Gangetic Plain contains perhaps 40% of India's population and 50% of its irrigated area. In the west (Punjab, Haryana) it covers one of India's most productive regions, in the east (Bihar, W. Bengal) one of its least productive. Between these extremes, there is a gradual transition in physical and socio-economic conditions, with rainfall, kharif cloud cover, surface flooding, rural population densities and subsistence farming generally increasing, and agricultural yields generally decreasing, from west to east. This paper argues that irrigated agriculture's relative success in the west and relative failure in the east can be very largely attributed to differences in rainfall. The paper reviews possible approaches to improved management given that it is inherently more difficult in the east than the west. It emphasizes that the first step must be to gain control since otherwise no management is possible. Since water is scarce relative to land, the objective must also be conjunctive use. Management is thus the key in large surface systems to the use not only of surface water but also of rainfall and groundwater. It may also be an important contributary factor to resolving drainage problems which in the east can be the dominant constraint and which in the west must be resolved if irrigated agriculture is to be sustained over large areas underlain by saline groundwater
