چکیده

هدف مطالعه حاضر بررسی اثر پایداری کشاورزی بر امنیت غذایی خانوارهای شهری ایران طی سال­های 94-1384 بود. بدین منظور، ابتدا سطح کلی پایداری کشاورزی با استفاده از یک شاخص ترکیبی پایداری کشاورزی و وزن­دهی سنجه ­ها بر اساس روش تحلیل سلسله‏ مراتبی (AHP) محاسبه شد. همچنین، برای تعیین وضعیت امنیت غذایی خانوارهای شهری، از شاخص کلی امنیت غذایی خانوار (AHFSI) استفاده شد. در نهایت، با استفاده از مدل فضایی مختلط خودرگرسیونی (SAR)، میزان اثرگذاری پایداری کشاورزی بر امنیت غذایی شهری در کنار سایر عوامل مؤثر مورد بررسی قرار گرفت. نتایج حاصل از مدل بیانگر تأثیر مثبت و معنی­دار پایداری کشاورزی بر امنیت غذایی خانوارهای شهری بود و با تئجه به معنی­دار بودن ضریب وقفه فضایی متغیر وابسته، وجود اثرات فضایی تأیید شد، به‏گونه‏ای که نتایج محاسبه اثرات مستقیم و غیرمستقیم شاخص پایداری کشاورزی بر امنیت غذایی هر استان و استان­های مجاور مثبت و معنی­دار بود. این نتایج حاکی از وجود سرریزهای درون­استانی و بین ‏استانی بوده و از این ‏رو، لازم است متولیان بخش کشاورزی با سرمایه ‏گذاری در زیرساخت ­های تولید مانند بذر، کود و روش‏های مناسب کشاورزی، به پیشبرد اقدامات خود در راستای افزایش توسعه کشاورزی و تولید پایدار بپردازند، که خود مقدم ه­ای برای استقرار امنیت غذایی پایدار است.

چکیده [English]

This study aimed at exploring the spatial effects of agricultural sustainability on food security of urban households in Iran over the period of 2005-15. For this purpose, first, the overall level of agricultural sustainability was calculated using a combination of agricultural sustainability and weighting indicators based on Analytic Hierarchy Process (AHP) method. Then, the household food security index (AHFSI) was used to determine the food security of households in urban areas. Finally, the effectiveness of agricultural sustainability on food security of urban households while other effective factors in place was examined using the mixed Spatial Autoregressive (SAR) model. The results of the model indicated a positive and significant effect of agricultural sustainability on food security in urban households, and the significance of the dependent spatial interruption coefficient confirmed the existence of spatial effects. So, the results of calculating the direct and indirect effects of agricultural sustainability index on the food security of each province and neighboring provinces were positive and significant. These results indicated the intra- and inter-provincial overflows. Therefore, it is imperative for policymakers of the agricultural sector to invest in production infrastructure such as seeds, fertilizers and agricultural practices with a focus on enhancing sustainable production as a prerequisite for the establishment of sustainable food security.
