ملخص المقالة :
ذرت به عنوان یکی از اساسی‌ترین فرآورده‌های زراعی، جایگاه و نقش استراتژیک مهمی در ایران دارد؛ به طوری که به عنوان یک محصول مهم در همه استان‌های ایران کشت می‌شود و کشاورزان از کشت آن کسب درآمد می‌کنند. اما این محصول نیاز به مصرف آب و کود بالایی دارد و همین امر منجر به آلودگی شدید آب‌های زیرزمینی می‌گردد و هزینه‌های گزافی را به محیط‌زیست وارد می‌نماید و کشت پایدار آن را به خطر می اندازد. بنابراین لازم است جایگاه هر استان با توجه به منافع اجتماعی حاصل از کشت ذرت مشخص گردد. از این‌رو، در این مطالعه ارزش کنونی منافع اقتصادی، هزینه‌های زیست‌محیطی و در نهایت منافع اجتماعی کشت ذرت‌دانه‌ای در استان‌های مختلف ایران طی دوره زمانی 1392-1379 محاسبه شد. به منظور محاسبه هزینه‌های زیست‌محیطی، آب خاکستری حاصل از کشت این محصول محاسبه شد. در نهایت منافع اجتماعی در استان‌های مختلف محاسبه و رتبه هر استان تعیین گردید. نتایج نشان داد که همه اس
