Abstract

The increase in demand and consumption level of human societies has led to excessive exploitation of natural capital and increase in ecological unsustainability in natural ecosystems, especially in Protected Areas (PAs). Therefore, the continuation of the process of using ecosystem services leads to an increase in ecological pressures and a decrease in the capacity of natural resources to meet human needs. Therefore, in the present study, the spatial-temporal changes of natural capital and the level of ecological sustainability in the Hara PAs from 1989 to 2021 were evaluated using the ecological footprint model. As the results revealed, among the existing uses, tidal zones have the most increasing trend and water areas show the most decreasing trend. In addition, the obtained results indicate that the extent of mangrove habitats has decreased during the studied years. Also, the performance and equivalence results among the uses of the region showed that the water areas (Aquaculture and fishing area) have assigned the highest equivalence coefficient and during this period, they show the greatest decrease in surface area. While mangrove forests with the lowest level of land use have the highest productivity coefficient. In the studied area, the ecological footprint has an increasing trend, the Biological Capacity (BC) is decreasing, and the Ecological Deficit (ED) is increasing. ensity of natural capital consumption and the decrease in capital accumulation during the studied years. Therefore, it is necessary to change the pattern of production and consumption to create ecological balance and control unsustainability in this area. On the other hand, preventing the increase of land cover/use changes as well as the protection of natural capital requires the creation of an integrated management for sustainable development and use of natural resources according to the region's BC.
