Wetlands play a critical role in regulating the hydrological cycle, preserving biodiversity, and improving water quality. However, urban expansion, intensive agriculture, and pollution have led to their rapid degradation, significantly reducing their ability to provide essential ecosystem services. The loss of wetlands exacerbates water scarcity, increases flood risks, and accelerates climate change impacts, endangering both human communities and natural ecosystems that depend on these environments.
To counteract these threats, this project focuses on the restoration of wetlands in Aragón, a region where ecologically significant wetlands have been heavily impacted by human activity. By employing a nature-based solutions approach, the initiative will recover wetland functions, ensuring sustainable water management, flood prevention, and ecosystem resilience.
The project follows the Volumetric Water Benefit Accounting (VWBA) and Water Quality Benefit Accounting (WQBA) methodologies, ensuring that the hydrological and ecological improvements achieved through wetland restoration are measurable, verifiable, and additional. The application of green infrastructure, ecological rehabilitation techniques, and sustainable land management will restore water retention capacity, improve filtration processes, and support biodiversity recovery.
By implementing strategic reforestation, hydrological reconnection, and pollutant reduction measures, this initiative will reduce flood risks, enhance water quality, and strengthen the long-term resilience of wetlands. Additionally, the project serves as a replicable model for sustainable wetland restoration, demonstrating how ecological conservation efforts can contribute to water security, climate adaptation, and sustainable development in Aragón and beyond.
The wetlands in Aragón face significant degradation due to various human-induced pressures.
The primary causes include:
Urban Expansion and Agricultural Development: The conversion of wetland areas for urban infrastructure and intensive farming has led to habitat loss, disruption of natural hydrological flows, and reduced capacity for groundwater recharge.
Pollution and Contaminants: Agricultural runoff, industrial discharges, and urban wastewater contribute to high levels of nitrogen, phosphorus, and heavy metals in wetlands, severely impacting water quality and aquatic life.
Climate Change and Hydrological Alterations: Rising temperatures and changing precipitation patterns have increased the frequency of droughts and floods, affecting the natural water retention capacity of wetlands and accelerating their degradation.
Decline in Biodiversity and Habitat Fragmentation: The loss of native vegetation and wetland connectivity has negatively impacted migratory bird populations and other key species, reducing the overall ecological integrity of these ecosystems.
The project integrates nature-based solutions (NbS), water quality improvement measures, hydrological restoration, and biodiversity conservation to restore wetland ecosystems and enhance sustainable water management.
1. Implementing Nature-Based Solutions (NbS)
To enhance water filtration and aquifer recharge, the project will develop artificial wetlands that naturally treat water before it enters groundwater systems. Additionally, riparian vegetation strips will be restored along wetland margins to improve habitat connectivity and prevent soil erosion. Designated infiltration zones will further support groundwater recharge by reducing surface runoff and minimizing land degradation.
2. Improving Water Quality
To mitigate pollution risks, the project will establish buffer zones with native vegetation, acting as natural filters to capture contaminants before they reach water bodies. Natural filtration channels will be created to reduce the concentration of agricultural and industrial pollutants. Sustainable farming practices will also be promoted to minimize fertilizer use and chemical runoff, further protecting water quality.
3. Hydrological Restoration for Balanced Water Flow
The project will re-establish natural floodplain connections to enhance water retention and prevent extreme fluctuations in wetland water levels. Eco-engineering solutions will be implemented to regulate water flow, ensuring a stable and well-distributed water supply across the wetland system.
4. Biodiversity Conservation and Ecosystem Monitoring
To restore wetland habitats, reforestation with native species will be conducted along wetland margins, reinforcing ecosystem stability. The project will also monitor key species to assess the progress of ecological recovery and ensure the long-term sustainability of wetland biodiversity.
By integrating hydrological restoration, pollution control, and habitat conservation, this project provides a comprehensive and sustainable approach to wetland restoration and water resource protection.
SDG 6 – Clean Water and Sanitation: Improves water quality through wetland filtration, reducing pollutants and increasing freshwater availability.
SDG 13 – Climate Action: Enhances climate resilience by mitigating flood risks, sequestering carbon, and stabilizing local microclimates.
SDG 15 – Life on Land: Contributes to biodiversity conservation by restoring degraded ecosystems and creating habitat connectivity for key species.
The project implementation will follow a structured approach to ensure effective wetland restoration and sustainable water management.

The Wetland Restoration Project in Aragón is designed as a scalable and replicable model for the rehabilitation of degraded wetlands, ensuring their critical role in integrated water resource management. The initiative aims to restore the natural functions of wetlands through nature-based solutions, enhancing water quality, improving biodiversity, and strengthening ecosystem resilience against climate change and human-induced degradation. By integrating advanced hydrological restoration techniques and sustainable land management practices, the project will generate long-term environmental, social, and economic benefits for the region.
A key component of this project is the establishment of adaptive management strategies, ensuring that wetland functions are continuously monitored and optimized. Through stakeholder engagement, including collaboration with local communities, industries, and environmental organizations, the project will promote shared responsibility and sustainable conservation efforts. Additionally, alignment with global sustainability frameworks such as the Ramsar Convention and the European Water Framework Directive will ensure that restoration efforts meet international standards and contribute to global conservation goals.
By preserving and rehabilitating Aragón’s wetlands, this project will play a crucial role in securing water security, carbon sequestration, and climate adaptation, mitigating the risks of extreme weather events while enhancing ecosystem services that benefit both nature and human communities. The initiative will serve as a benchmark for future wetland restoration projects, reinforcing the importance of nature-based solutions in water governance and sustainable development.
