چکیده
افزایش جمعیت در سطح دنیا و بالا رفتن میزان تقاضای آب در اکثر نقاط دنیا، مشکلات زیادی را در توزیع و تخصیص منابع آبی در بخشهای مختلف شرب، صنعت و کشاورزی بهوجود آورده است. دشت اردبیل بهدلیل قرار گرفتن در اقلیم سرد و خشک در تأمین آب مصرفی بخش کشاورزی با مشکل کمآبی مواجه است. یکی از راهکارهایی که میتواند تا حدودی این مشکل را حل کند مدیریت جامع آب است که یک روش اقتصادی دارای اهمیت بوده و با ارزشگذاری میتوان بین عرضه و تقاضای آب تعادل ایجاد کرد. در این مطالعه برای تعیین ارزش اقتصادی آب در تولید محصولات سیبزمینی و یونجه از روش تابع تولید استفاده شد. نتایج به‌دست‌آمده نشان داد که متوسط مقدار تولید نهایی نهاده آب آبیاری برای محصول سیبزمینی و یونجه به‌ترتیب برابر با 459/0 و 125/0، با ارزش اقتصادی 8/11486 و 4/2759ریال بر مترمکعب می‌باشد. همچنین بالاترین میزان مصرف آب در تولید سیبزمینی و یونجه به ترتیب برابر با 14400 مترمکعب و 10000 مترمکعب در هکتار و میانگین مصرف آب به ترتیب برابر با 03/12091 و 52/6786 مترمکعب در هکتار به‌دست آمد. در نتیجه با آگاهی دادن به کشاورزان بابت پیامدهای برداشت بیرویه از منابع آبی و اصلاح قیمت آب کشاورزی بر اساس ارزش نهایی تولید، میتوان از هدررفت و مصرف بیرویه آب در بخش کشاورزی جلوگیری کرد.

چکیده [English]
Population growth around the world and rising water demand in most parts of the world have caused many problems in distributing and allocating water resources in different sectors of drinking, industry and agriculture. Ardebil Plain has a shortage of water due to its cold and dry climate in providing water consumption of agriculture. One of the ways that can some extent solve this problem is comprehensive water management, which is an important economic method and values can be balanced between supply and water demand. In this study, the production function was used to determine the economic value of water in the production of potato and alfalfa products. The results showed that the average final production of irrigation water input for potato and alfalfa product was 0.459 and 0.25, with economic value of 11486.86 and 2759.4 Rials per cubic meter respectively. Also, the highest amount of water consumption in potato and alfalfa production was obtained by 14400 cubic meters and 10,000 cubic meters, respectively, and average water consumption, respectively, was 12.03 and 6786.52 cubic meters, respectively. As a result, by informing farmers about the consequences of unnecessary harvesting of water resources and reforming agricultural water prices based on the ultimate value of production, the loss and unnecessary consumption of water in the agricultural sector can be prevented.
