چکیده
امنیت غذایی  دارای ابعاد گوناگون در حوزه‏ های اقتصادی، اجتماعی، فرهنگی، منابع طبیعی و محیط زیست و از مهم‏ترین مؤلفه‌های توسعه است. منابع طبیعی و محیط زیست در حیات و توسعه جوامع بشری و برقراری امنیت غذایی نقش و اهمیت به‏سزا دارند. در مطالعه حاضر، اثر انتشار آلودگی و بهره‌برداری از منابع طبیعی بر امنیت غذایی در ایران در قالب الگوی VECM در دوره زمانی 1371 تا 1396 بررسی شد. نتایج مطالعه نشان داد که در دورة مورد بررسی، اثر بهره‌وری انرژی در بخش کشاورزی، ارزش افزوده بخش کشاورزی و بهره‌برداری از منابع طبیعی بر شاخص امنیت غذایی ایران مثبت است؛ همچنین، متغیرهای انتشار گاز دی‏اکسید کربن در بخش کشاورزی و نرخ بیکاری بر امنیت غذایی اثر منفی دارند؛ ضریب متغیر ECM نیز نشان­دهندة آن است که در هر دوره، 73/5 درصد از خطای عدم تعادل از بین خواهد رفت. از این‏رو، با توجه به اثرگذاری مثبت بهره‌وری انرژی، ایجاد زیرساخت لازم برای ارتقای آن در بخش کشاورزی به ‏منظور افزایش تولیدات  این بخش و در نتیجه، کاهش انتشار آلودگی در راستای بهبود امنیت غذایی توصیه‌ می‌شود.

چکیده [English]
Food security has various dimensions in the economic, social, cultural, natural resources and environmental fields, which is one of the most important components of development. Natural resources and the environment play an important role in the life and development of human societies and the sustainability of food security. In the present study, the effects of pollution emission and exploitation of natural resources on food security in Iran in the form of VECM model in the period of 1992-2017 were investigated. According to the results, energy productivity in the agricultural sector, value added in the agricultural sector and the use of natural resources in the studied period had a positive effect on Iran's food security index; in addition, the variables of carbon dioxide emission in the agricultural sector and the unemployment rate had a negative effect on the food security. The coefficient of the ECM variable indicated that in each period, 5.73 percent of the imbalance error would disappear. Establishing the necessary infrastructure to improve energy productivity in the agricultural sector, in order to increase production in this sector and thus, reduce the spread of pollution is recommended to improve food security, given the positive impact of energy efficiency.
