مقدمه و هدف: با توجه به تغییر الگوی کشت شهرستان گرگان به سمت محصول برنج به عنوان یک محصول آب بر از یک طرف و افت سطح سفره آب زیرزمینی از طرف دیگر، اهمیت مطالعه مدیریت منابع آب و شناخت عوامل موثر بر تقاضای آب را بیش از پیش نمایان می‌کند.
مواد و روشها: یافتهها:در این مطالعه به برآورد تابع تقاضای آب در تولید محصول برنج، با استفاده از روش‌های سیستمی و رگرسیونهای به ظاهر نامرتبط (SUR) پرداخته شد. داده‌های مربوط به این پژوهش در سال 97-1396 از راه تکمیل 314 پرسش‌نامه به روش نمونه‌گیری طبقه‌ای تصادفی از شالی‌کاران شهرستان گرگان بدست آمد.
بحث و نتیجهگیری: تقاضای آب کشش پذیر نیست، یعنی با افزایش قیمت آب تقاضای آب کاهش قابل توجهی نخواهد داشت. بنابراین پیشنهاد می‌شود در کنار ابزار قیمت آب از سیاست‌های تکمیلی نظیر افزایش راندمان و استفاده از روش‌های مدرن آبیاری نیز استفاده شود.
