Productivity and equity of different irrigation schedules under limited water supply
journal contribution
posted on 2008-09-24, 10:43 authored by Ian Smout, S.D. GorantiwarSome irrigation schemes with limited water supply in Central and
Southern India follow the area proportionate water distribution based on assumed
uniform characteristics of the command area (planned schedule). However in most
cases, this planned schedule is overridden by the practice in which users at head draw
more than their share of water (actual schedule) due to human factors and technical
limitations of the planned schedule. This practice is highly inequitable as users at tail
end do not get any water. This paper considers alternative schedules based on full
irrigation or deficit irrigation within the framework of area proportionate water
distribution in such irrigation schemes and presents the simulation-optimisation
technique to develop the corresponding land area and water allocation plan for different
allocation units by considering the heterogeneity of the irrigation scheme. This paper
further demonstrates the utility of proposed alternative schedules by comparing the
productivity and equity of these schedules with planned and actual schedules for one
irrigation scheme in Central India. The results show that the actual schedule reduces
both productivity and equity greatly and the productivity and equity with the alternative
schedules are higher than with the planned schedule. The results also show that deficit
irrigation has great potential to increase both productivity and equity of irrigation
schemes.
