چکیده

یکی از محدودیت­های استفاده از نهاده­ها­ در بخش کشاورزی انتشار آلاینده­های مختلفی می­باشد که اثرات منفی بر محیط زیست دارند‌. در این تحقیق اثرات زیست‌محیطی در تولید و انتقال محصول کلزا به دروازه کارخانه روغن‌کشی در چهار سناریو مختلف شامل: بهره‌برداران ناحیه مرکزی، ناحیه شمالی و کشت و صنعت مغان با دو روش آبیاری سطحی و بارانی در استان اردبیل به روش ارزیابی چرخه حیات مورد تجزیه‌و‌تحلیل قرار گرفت. اطلاعات لازم برای این تحقیق با استفاده از پرسش‌نامه و مصاحبه با کشاورزان و مسئولین سازمان‌های مربوطه استان اردبیل به دست آمد. نتایج ارزیابی چرخه حیات نشان داد که نهاده‌های کود نیتروژن، سوخت و الکتریسیته بیشترین سهم را در شاخص‌های زیست محیطی مورد مطالعه دارا می‌باشند و شاخص‌های زیست‌محیطی مسمویت آب‌های آزاد، پتانسیل اختناق دریاچه‌ای، اسیدیته و گرمایش جهانی نسبت به سایر گروه‌های اثر دارای اثرات زیست محیطی بیشتری می‌باشند.

چکیده [English]

One of the limitations regard to input use in agriculture is various emissions that have negative effects on natural environment. In this research, environmental impacts in canola production and transportation to oil extracting factory gate in Ardabil Providence were studied based on life cycle assessment considering four scenarios including central and north regions and Moghan Agro-Industrial & Livestock Co. with surface and sprinkler irrigation methods. The required information in this study was gathered using questionnaires and interviews with farmers and staffs of the related organizations in Ardabil Province. The results of life cycle assessment showed that nitrogen fertilizer, fuel and electricity inputs had the highest share of environmental indicators. Also, indicator normalization showed that free water ecotoxicity, eutrophication, acidification and global warming had more environmental impacts than other indicators.
