“…The ecological footprint is a powerful indicator of the sustainability of development, as it considers the dynamics that are associated with the pressure that is exerted on the environment by the use of (renewable and non-renewable) resources as inputs and various outputs (such as waste or CO 2 ) [15]. The ecological footprint was modified to deal with assessing several applications such as the exergy based ecological footprint [16][17][18], water footprint [19], pig-biogas-fish system [20], fruit production systems [21], etc. Therefore, the ecological footprint can be utilized to measure the dependency of both consumers and producers on the global ecosystem [22].…”
