| چکیده | ||
| بخش کشاورزی بیشترین مصرف آب را به خود اختصاص داده است. از این‌رو، تعیین ارزش اقتصادی آب به عنوان یک کالای اقتصادی و راندمان مالی کشاورزان از اهمیت ویژه‌ای برخوردار است. هدف اصلی مقاله حاضر تعیین ارزش اقتصادی آب کشاورزی و راندمان مالی کشاورزان در شهرستان خنداب از استان مرکزی است. برای این منظور محاسبه میزان عملکرد محصولات زراعی گندم، جو، یونجه و ذرت یک مدل ریاضی بومی استفاده شد. قیمت آب کشاورزی از سه روش وزن‌دهی بر اساس حجم آب مصرفی، مساحت زیرکشت و درآمد حاصل از هر محصول به دست آمد. در بین روش‌های مذکور، روش وزن‌دهی بر اساس حجم آب مصرفی به عنوان مناسب‌‌‌‌‌‌ترین روش انتخاب شد. راندمان مالی کشاورزان برای سه حالت، آب رایگان، دریافت 10 درصد قیمت محاسبه شده و دریافت تمام قیمت آب از کشاورز محاسبه شد. نتایج نشان داد که حساسیت راندمان مالی به تغییرات درآمدها بیشتر از تغییر در میزان هزینه‌ها می‌باشد. همچنین، نتایج نشان داد که راندمان آبیاری و راندمان مالی در همه موارد هم راستا نیستند. در صورت دریافت 10 درصد قیمت محاسبه شده آب از کشاورز، امکان اجرای سیستم آبیاری تحت فشار فراهم خواهد شد و راندمان مالی کشاورزان نیز افزایش خواهد یافت. | ||

| چکیده [English] | ||
| Since the agricultural sector is the largest consumer of water resources, it is important to determine economic value of water and financial efficiency of farmers. The purpose of this paper is to determine the economic value of water and financial efficiency of farmers in Khondab County, Markazi Province. In this study, the performance of four crops including wheat, barley, alfalfa and corn were calculated, involving a newly developed mathematical model. The average price of agricultural water has been determined using three methods: weighting methods based on the volume of water, the cultivated area, and the income for each plant. Among the methods, the method based on volume of water has selected as the most appropriate method. Financial efficiency was calculated for three modes including: free water, 10% of the calculated price, and the actual price of water from the farmer. Results show that financial efficiency is sensitive to changes in income more than changes in costs. Irrigation efficiency and financial efficiency are not similar in all cases. It is possible to perform pressurized irrigation if 10% of the calculated price would be received from farmers. | ||
