سیستم های باز تو در تو: یک مفهوم مهم در استفاده از تجزیه و تحلیل اثرات زیست محیطی برای ارزیابی توسعه پایدار

The calculation procedures and index interpretation of ecological footprint (EF) analysis, a method for assessing sustainable development (SD), have been continuously improved since the early 1990s. To identify potential for further improvement, this study compared the information revealed by existing EF applications for SD assessment with the core concerns of SD and found that intra-generational equity has not been appropriately addressed in the existing applications of EF analysis for SD assessment because the concept of nested open systems has been ignored. This study then argued that the concept of nested open systems should play a critical role in addressing global SD and conducting national EF analysis for SD assessment. Finally, the potential for improving EF analysis for SD assessment at the global and national scales was discussed.
