Modeling wetland restoration scenarios in Gavkhooni International Wetland

Abstract

One of the challenges for managers is to ensure the long‐term sustainability of wetlands by protecting their ecological values against natural and human pressures. This study has evaluated the past vulnerability status of Gavkhooni International Wetland, Isfahan, Iran, using a combination of GIS and multicriteria spatial decision support systems (MC‐SDSS) processes, to propose restoration scenarios. Three scenarios were developed from criteria established using field studies and expert opinion: (1) wetland restoration to preserve existing water bodies, (2) determination of susceptible regions as habitat replacement for aquatic communities, and (3) a combination of the two previous scenarios. Finally, a map was developed classifying the regions into five categories by area of priority. The northern regions of the wetland were prioritized based on the results of the first and the second scenarios. The third scenario provided the highest opportunity to obtain an optimistic state, that is, normal conditions, for the wetland marginal regions, especially in the central region (between the east and west). In a pessimistic state and optimistic state of the third scenario, almost all parts of the center to the south of the wetland show the lowest priority restoration scenarios. According to the different scenarios, the central regions of the wetland are less affected by agricultural activities and human settlements. In general, the results show that the Gavkhooni Wetland is unstable based on functional, environmental, social and economic conditions. According to the criteria and the MC‐SDSS model, the government can adopt and implement the necessary policies and programs to improve the condition of the wetland.

Research on Innovative Design Mode of Wetland Landscape Ecological Restoration in the Era of Artificial Intelligence

“…Times in the high-speed development, rapid socio-economic development, and economic and social prosperity behind a prosperous scene are all kinds of uncontrolled exploitation and depletion of resources, more and more land on the construction of skyscrapers and roads and bridges to adapt to the development of mankind [1][2]. Therefore, the environment is polluted and destroyed, resources are depleted, and there is a serious ecological imbalance [3].…”

Synthesis of special feature —Tailored Restoration Response: Predictions And Guidelines For Wetland Renewal

“…(P19): Following a 30-fold reduction in size of the freshwater Gavkhooni Wetland in the central plateau of Iran, as reported between 1993 and 2020, Zefrehei et al (2023) employed models to evaluate and propose the most viable restoration scenarios. The scenarios were produced with the use of a geographic information systems and multicriteria spatial decision support systems.…”
