Computer Aided Conjunctive Use of Water

摘要

Water, a single finite natural resource, is one of the most important critical inputs for agricultural production. National Water Policy, 1987 in India recognized the need for conjunctive use of surface water and ground water and recommended that conjunctive use should be ensured from project planning stage and should form an essential part of project. Many theoretical studies were carried out by researchers, planners and policy makers and it was concluded that conjunctive use should be promoted but except few studies of conjunctive use of fresh water and saline ground water, in reality there is no evidence of conjunctive use in practice. Though good quality shallow ground water zones are available in Bihar, India, but due to large difference in cost of canal water and ground water farmers don’t adopt conjunctive use practice.
