Evaluation of Irrigation Scheme Performance of Asagi Pasinler Plain (2012-2016)

Abstract

Undesirable levels of system performance in the irrigation project areas may lead to crop production losses and a decrease in sustainable irrigation area. Whether or not the expected benefits of irrigation investments aimed at transforming limited water resources into economic benefits by providing an increase in crop production can be understood from the monitoring and evaluation results of irrigation performances. This research was conducted to evaluate the irrigation system performance of Asagi Pasinler Plain irrigation project area which is managed by the Aras Irrigation Association between 2012 and 2016. As a result of the survey, it was determined that the annual net water supply ratio for the area of total 4610 and net 3900 hectares opened for irrigation in 2012-2016 is between 5.25 and 10.68 and the annual total water supply ratio varies between 2.23 and 4.54. Sustainable irrigation area ratio was between 25.64% and 51.28%. The production rate ratios in these years are between 15.20% and 38.48%, and the profitability ratios have changed over a very wide range from-0.11 to 9.32. The financial efficiency ratio is between 5.66% and 87.36%, the financial adequacy ratio is between 0.96 and 4.72, and the collection rate is between 29.70% and 100%. © 2018, Centenary University.
