هدف: مشکلات زیستمحیطی جهانی و منطقهای به دلیل رشد قابلتوجه جمعیت و توسعه سریع اجتماعی-اقتصادی به طور فزایندهای برجسته شدهاند. این مشکلات مانند فرسایش خاک، آلودگی اکولوژیک، تخریبزمین، از بین رفتن تنوعزیستی و کاهش خدمات اکوسیستمی، محیط زندگی انسانها و توسعه پایدار اقتصادها و جوامع را به طور جدی تهدید میکنند. بنابراین با توجه به رشد جمعیت و توسعه فعالیتهای اقتصادی و در نتیجه استفاده بیشتر از منابع اکولوژیکی، ارزیابی امنیت اکولوژیکی حائز اهمیت میباشد. ارزیابی امنیت اکولوژیکی یکی از ابزارهای مهم برای سنجش تأثیرات فعالیتهای انسانی بر محیطزیست و منابعطبیعی است. روش پژوهش: این ارزیابی معمولاً با استفاده از دو مفهوم کلیدی ردپای اکولوژیکی و ظرفیت اکولوژیکی، انجام میشود. برای این منظور سرانه ردپای اکولوژیکی و ظرفیت اکولوژیکی استان فارس طی دوره زمانی 1400-1390 محاسبه شد. در نهایت با توجه به نتایج بدست آمده در این زمینه شاخصهای کسری اکولوژیکی (ED)، شاخص تنوع ردپای اکولوژیکی (EFDI)، شاخص فشار اکولوژیکی (EPI)، و ضریب هماهنگی اکولوژیکی ( (ECCجهت ارزیابی امنیت اکولوژیکی محاسبه شدند. یافتهها: نتایج این مطالعه نشان داد که سرانه ردپای اکولوژیکی استان فارس در طی دوره مورد مطالعه، بیش از 17 درصد افزایش یافته که درکنار رشد جمعیت استان، نشاندهنده افزایش فشار بر منابعطبیعی موجود در استان است. از سوی دیگر سرانه ظرفیت اکولوژیکی استان با کاهش 10درصدی مواجه شده است. همچنین این نتیجه بدست آمد که سرانه ظرفیت اکولوژیکی استان فارس کمتر از یک چهارم سرانه ردپای اکولوژیکی این استان میباشد که نشانگر آسیبپذیری توانایی جذب و بازیابی منابعطبیعی و محیطزیست استان است. بعلاوه محاسبه چهار شاخص امنیت اکولوژیک همگی بیانگر ناامنی اکولوژیکی استان و عدم هماهنگی بین جریان توسعه و محیطزیست میباشد. نتیجهگیری: با توجه به نتایج بهدستآمده با استفاده از شاخصهای مورد بررسی در این تحقیق، مشخص شد که وضعیت محیطی استان مناسب نبوده و به مرور زمان بدتر شده است. بنابراین اگر سیاستگذاران به دنبال توسعه اقتصادی پایدار هستند، توجه بیشتر به محیط زیست استان ضروری است. در نتیجه، اجرای پایش محیطی پویا و دورهای و ارزیابی استراتژیهای مدیریتی برای ارتقای سلامت محیط ضروری است. | ||

چکیده [English] | ||
Objective: Global and regional environmental issues have become increasingly significant because of rapid population growth and socioeconomic development. Problems such as soil erosion, ecological pollution, land degradation, loss of biodiversity, and diminished ecosystem services pose serious threats to human living conditions and sustainable development of economies and societies. Consequently, as the population increases and economic activities expand, leading to greater consumption of ecological resources, assessing environmental security becomes crucial. This study aims to develop a comprehensive, multi-faceted approach to evaluate the environmental security of Fars Province by utilizing an ecological footprint method. Method: Typically, this evaluation employs two fundamental concepts: ecological footprint and ecological capacity. In this context, the per capita ecological footprint and ecological capacity of Fars province were analyzed for the years 2011 to 2021. After determining the per capita ecological footprint and capacity, four indices were calculated: ecological deficit (ED), ecological footprint diversity index (EFDI), ecological pressure index (EPI), and ecological coordination coefficient (ECC). Results: The results of this study showed that the per capita ecological footprint of Fars province increased by more than 17% during the study period, which, along with the population growth of the province, indicates an increase in pressure on the natural resources. Additionally, pollution levels and agricultural production contributed significantly to this strain. On the other hand, the per capita ecological capacity of the province, dropping from 1.23 gha in 2011 to 1.11 gha in 2021 has increased by 10%. It was also concluded that the per capita ecological capacity of Fars province is significantly lower (less than one-fourth) than its per capita ecological footprint, underscoring the region's vulnerability in terms of its capacity to absorb and regenerate natural resources. The findings indicated that throughout the study period, Fars Province consistently experienced an ecological deficit, which has been rising over time. Furthermore, the assessment of four environmental security indicators all indicate the province's environmental insecurity and the lack of coordination between development and the environment. Conclusions: According to the results obtained using the investigated indicators in this study, the environmental condition of the province is not suitable and it has worsened over time. Therefore, if the policymakers are looking for sustainable economic development, it is necessary to pay more attention to the province's environment. In other words, it is imperative to implement dynamic and periodic environmental monitoring and to evaluate management strategies to enhance environmental health. | ||
