| Abstract | Water pricing is an effective tool to efficiently tackle Water Scarcity. Agriculture has the highest water-saving perspective. Pakpattan command area of Punjab, Pakistan produces wheat, Potato, Cucumber, and maize crops in large quantities. The canal water, that is insignificant for irrigating the crops, is diverted to the fields by the system of canals and distributaries. For the protection of these huge structures, the farmers are charged on a seasonal basis. The current water prices are brutally criticized for not being enough to accurately operate the complete structure. Residual value method was used to evaluate the value of the water and then based on the amount of irrigation water distributed to farms linked with the infrastructure maintenance cost; full cost recovery numbers are achieved for the study area for the five crops under study. To investigate the value and pricing of water under different irrigation Methods at Farm level, a field Questionnaire survey was performed, and 302 farmers were interviewed about their inputs and outputs from the five crops under different irrigation Methods. The value of irrigation water was assessed, by using the Residual value method, and water price under each irrigation method was calculated. The economic value of water was divided into two types, use, and nonuse value. The huge difference was found between the gross margins under flood and drip for all the crops under study by using drip irrigation average increase of 80% in gross margin was observed. For drip, the increase in gross margin was 210%, 70%, 84%, 12%, and 26 % of the gross margin under flood irrigation for wheat, potato, cucumber, spring maize, and autumn maize. For sprinklers, the gross margin was increased in case of wheat 129 % as compared to flood but it decreased 9% for potato under furrow irrigation. The value of the water was also increased by 148% of the value of water under flood for drip irrigation for all crops. Water-saving under drip was noticed on an average of 27% as compared to flood and under the sprinkler, it was 19%. The prices were also very less for HEIS. The results revealed that the canal water is severely undercharged in the culturable command area of selected distributary, thus denying the idea of having an economically self-sustainable irrigation system. |
