Economic and Social Value of Irrigation Water: Implications for Sustainability
The economic value of irrigation water was determined through Contingency Valuation Method and Crop-Water Production function during wet and dry season of paddy cultivation. Factors namely, area under rice and water requirement influenced the willingness to pay for water by farmers. Social values of farmers’ over water were found to be high. The comparison of the economic value of water estimat...
متن کاملAssessment of Water Quality Used for Irrigation: Case Study of Josepdam Irrigation Scheme
The aim of irrigation is to recharge the available water in the soil. Quality of irrigation water is essential for the yield and quality of crops produced, maintenance of soil productivity and protection of the environment. The analysis of irrigation water arises as a need to know the impact of irrigation water on the yield of crops, the effect, and the necessary control measures to rectify the...
متن کاملUsing Bayesian Belief Networks to make integrated irrigation management decisions - A case study from Sri Lanka
It is now widely accepted that successful irrigation management requir~s consideration of a number of physical, socio-economic and institutional factors. However, as these factors often interact in complex ways it is not always easy to do this. This paper presents an approach which is able to represent complexity in a simpie, yet rigorous, way and facilitates integrated analysis of data from a ...
متن کاملValue of irrigation water with uncertain future rain: A simulation case study of sugarcane irrigation in northern Australia
[1] Using sugarcane as a case study, this paper shows how an agronomic model can be used to estimate the marginal value of stored irrigation water with uncertain future rain. We do this by estimating production functions that have the water available for use as the variable factor of production (referring to them as allocation production functions). These differ from more ‘‘traditional’’ produc...
