| مقدمه و اهداف: گندم یکی از سه غله مهم در تأمین غذا و معیشت بسیاری از ساکنان زمین است. این موضوع موجب شده تا در مدیریت نظامهای تولید گندم با هدف افزایش بهرهوری و عملکرد، مصرف نهادهها حداکثر گردد. به دلیل اهمیت تأثیر نهادههای نظامهای تولیدی بر ظرفیت زیستی و اثر آن بر پایداری تولید، در این مطالعه سعی شده است پایداری این نظامها با تکنیکهای جدید مورد ارزیابی قرار گیرد. مواد و روشها: در این تحقیق، بهمنظور ارزیابی پایداری از روش ردپای امرژی و شاخصهای برگرفته از آن استفاده شده است. این روش توانایی کمیکردن تأثیر فعالیتهای انسان بر منابع اکولوژیک نظام تولیدی و اکوسیستمهای اطراف را دارد. دادههای موردنیاز برای این مطالعه در سال زراعی 1402-1401 از منابع مختلف مانند مصاحبه با کشاورزان و مدیران نظامهای تولیدی در ایرانشهر و همچنین اطلاعات اداره هواشناسی گردآوری شد. یافتهها: پس از جمعآوری و تحلیل دادهها، نتایج نشان داد که مدیریت نظامهای تولیدی در حال حاضر موجب کاهش ظرفیت زیستی (107×85/3 هکتار جهانی در یک سال زراعی) نسبت به ردپای امرژی (108×12/8 هکتار محلی در یک سال زراعی) در منطقه هدف شد. این امر باعث شد تا نظامهای تولید گندم در منطقه با کسری اکولوژیک (108×73/7- هکتار) مواجه باشند و امنیت اکولوژیک نظامها و محیط اطراف آنها به مخاطره بیفتد. نتیجهگیری: باتوجهبه اینکه تولید گندم در ایرانشهر با افزایش تقاضای اکولوژیک همراه بود، استفاده اصولی از نهادهها میتواند در حفظ منابع اکولوژیک مؤثر باشد. | ||
