Abstract
Introduction: Each ecosystem provides essential goods and services that support human needs and community well-being. However, wetlands in both Iran and globally are confronted with significant challenges, including reduced area, water pollution, and changes in land use, all of which threaten their sustainability. Consequently, the protection of these critical ecosystems is crucial for their sustainable management. To address this, the DPSIR framework has been developed in recent years to assess environmental changes and analyze the impacts of human activities on the environment. Therefore, the present study aims to evaluate the environmental status of Alagol Wetland using the DPSIR framework and to explore the cause-and-effect relationships between human activities and environmental impacts.
Materials and Methods: This study was conducted in four main steps: identifying the driving forces affecting the status of wetlands, examining the pressures on the current environmental condition and assessing the negative impacts; adapting and localizing the data for the Alagol Wetland through field visits and interviews with local residents and experts; describing the environmental condition of the Alagol Wetland within the DPSIR framework and identifying and proposing the most significant solutions to reduce, compensate or resolve the issues facing the studied wetland, using a Likert-scale questionnaire.
Results: The study findings indicated that population growth, climate change, development of settlements and rural areas, water demands of surrounding communities, road and transportation infrastructure development, lack of integrated management, weak regulations, agricultural activities, tourism, industrial growth and development, aquaculture and fisheries, livestock farming and excessive grazing are the primary driving forces that, through a series of cause-and-effect relationships, have led to pressures, conditions and impacts. To manage these effects and improve the status of the wetland, 65 response strategies were presented. After evaluation by experts, the most important strategies were identified for each driving force. Key strategies include monitoring peripheral lands and defining wetland boundaries, using modern irrigation systems, preventing land grabbing, integrated water management, adhering to environmental development requirements as per the National Land Use Master Plan, promoting a comprehensive wetland management approach, maintaining hydrological balance in the basin, planning tourism development in accordance with regional capacities, applying advanced technologies in conservation, preserving native aquatic species and zoning appropriate grazing areas around the wetland.
Discussion: The environmental status assessment of Alagol Wetland using the DPSIR model clarifies the cause-and-effect relationships between human and natural factors and their impacts on the wetland ecosystem. Driving forces such as population growth and climate change exert pressure on the wetland environment, leading to negative changes in water quality, habitats and biodiversity. Since these changes pose serious threats to the wetland's sustainability, identifying and implementing management solutions is essential. The proposed measures, alongside strengthening integrated management and active community participation, require continuous monitoring, sufficient resource allocation and the development of effective regulations for the protection of this valuable ecosystem. In this regard, the developed indicators of the DPSIR model can serve as effective tools for policymakers and managers in planning and decision-making processes related to the conservation of Alagol Wetland.
