| محدودیت منابع آب و افزایش جمعیت سبب شده است که بخش کشاورزی نسبت به سایر بخشهای مصرف‌کنندۀ آب تقاضای بیشتری داشته باشد. بنابراین، امروزه چالش بخش کشاورزی تولید غذا با استفاده از آب کمتر است. تحقیق حاضر در سال 1397ـ 1398 در دشتهای استان تهران و بر اساس اطلاعات موجود جهاد کشاورزی انجام شده است. از این‌رو، هدف از انجام تحقیق حاضر، بررسی عوامل تأثیرگذار بر پایداری منابع آب است. در تحقیق پیش رو ابتدا 110 نفر از تولیدکنندگان براساس فرمول کوکران به عنوان حجم نمونه تعیین شدند و در آن از پرسشنامه برای تجزیه‌وتحلیل استفاده شد. نمونهگیری به صورت تصادفی از میان تولیدکنندگان محصولات کشاورزی انجام شد. پایایی پرسشنامه با استفاده از ضریب آلفای کرونباخ در بازۀ 75ـ 93 درصد با استفاده از نرم‌افزار SPSS تأیید شد. سپس، تابع تولید کاب داگلاس به عنوان تابع تولید مناسب آورده شد و با استفاده از قضیۀ شپرد تابع هزینۀ تولید و تابع تقاضا برای آب کشاورزی محاسبه شد. ارزش افزودۀ بخش کشاورزی متغیر وابسته تابع و متغیرهای مستقل نیز شامل متغیرهای اقتصادی، اجتماعی و فنی در نظر گرفته شدند. تجزیه‌وتحلیل داده‌ها با نرم‌افزار SPSS انجام شد. نتایج همبستگی نشان داد بین مدیریت پایدار منابع آب با متغیرهای عوامل اقتصادی و سپس، با دیدگاه کارشناسان ارتباط معناداری در سطح 99 درصد وجود دارد. بین سن و سابقۀ کارشناسان و پایداری آب رابطۀ معناداری وجود ندارد و به بیانی دیگر، این عوامل مستقل از مدیریت پایدار آب هستند. | ||

| چکیده [English] | ||
| Limited water resources and population growth have made the agricultural sector more in demand than other water-consuming sectors, so today the challenge for the agricultural sector is related to food production using less water. This case study was conducted in the plains of Tehran province in 1397-98 and it is based on the information available in agricultural management of Tehran province. Therefore, the purpose of this survey is to investigate the challenges and factors affecting the sustainability of water resources management. First, we did random sampling from agricultural producers and 110 producers determined based on Cochran's formula as the sample size. The reliability of questionnaire determined between 75%-93% by Cronbach's alpha index with SPSS. Then the appropriate production function called Cobb–Douglas production function is given and using the shepherd theorem, the production cost function and then Demand function for agricultural water has been calculated. The added value of the agricultural sector was considered as a dependent variable and independent variables including economic, social and technical variables. According to the results of the correlation test, there is a significant relationship between sustainable management of water resources and the variables of economic factors and then the views of experts is at the level of 99%. There is no significant relationship between age and background of experts and water sustainability. In other words, these factors are independent of sustainable water management. | ||
