Wetlands and restoration
Despite being the world’s most productive ecosystems and crucial to human well-being, wetlands continue to experience extremely high rates of decline and degradation: an estimated 35% of wetlands have been lost since the 1970s. To prevent further losses and secure the necessary ecosystem services that wetlands provide – such as water purification, climate change mitigation, food and building materials, and flood control – the restoration of these important inland water and coastal systems are urgently required.
Ecosystem restoration has increasingly become a priority for scientists, politicians, officials and environmental activists in recent years as a critical approach to curb biodiversity loss and promote resilience to climate change. As such, the UN Decade on Ecosystem Restoration, a 10-year push to halt and reverse the decline of the natural world, was launched in 2020. Through this year’s Wetlands Day theme, the UN Convention on Wetlands is calling for global restoration efforts to include the rehabilitation of wetlands.
Restoration acknowledged at high-level UN meetings
In 2022, urban wetlands were recognized as critical to human well-being at the UN Convention on Wetlands’ 14th Conference of Parties. During Ramsar COP14 in Geneva and Wuhan, Parties were called upon to take appropriate and urgent measures to achieve the goal of halting and reversing the loss of wetlands globally.
Also in 2022, the UN Convention on Biological Diversity’s 15th Conference of Parties in Montreal and Kunming witnessed the adoption of the Kunming-Montreal Global Biodiversity Framework, which includes under its Target 2 an aim that, by 2030, at least 30% of areas of degraded terrestrial, inland water, and coastal and marine ecosystems are under effective restoration.
It’s time for restoration of urban wetlands
The loss of wetlands noted above is particularly prevalent in cities. Urban wetlands are vulnerable to the adverse impacts of urbanization as they tend to be undervalued and therefore often converted or used as dumping grounds. However, while the challenges of urbanization to wetland health are profound, so too are the opportunities for wetland restoration.
As part of the newly adopted Kunming-Montreal Global Biodiversity Framework mentioned above, Parties adopted the decision titled Engagement with subnational governments, cities and other local authorities to enhance implementation of the post-2020 Global biodiversity framework and its accompanying revised Plan of Action on Subnational Governments, Cities and Other Local Authorities (2022-2030), which recognizes the vital role that cities and local authorities play in the implementation of the Global Biodiversity Framework – including by restoring urban wetlands and thereby contributing to Target 2. On the CitiesWithNature Action Platform, the CBD-recognized platform for cities to use for monitoring and reporting on their actions for biodiversity, the restoration and protection of urban wetlands can be recorded by Cities under Commitment 1 titled “Protect, Connect and Restore Ecosystems” and specified under two actions: “a) Restore and/or rehabilitate terrestrial, freshwater, and coastal ecosystems” and “(b) Increase protected areas.”
Globally, cities are increasingly acknowledging the importance of protecting and restoring wetland areas. To acknowledge cities’ significant contributions to take care of valuable urban wetlands, the UN Convention on Wetlands established the Wetland City Accreditation Scheme.
Wetland City Accreditation – Encouraging a positive relationship with urban wetlands
The Wetland City Accreditation (WCA) scheme was launched in 2015 – during the Ramsar Convention on the Conservation of Wetlands COP12 in Uruguay – with the aim of improving local authority or authorities’ work in conservation and wise use of wetlands. The accredited Wetland Cities are intended to act as models for the study, demonstration and promotion of the Convention on Wetlands’ objectives, approaches, principles and resolutions. Cities become candidates for accreditation by applying to the official call for applications posted here.
The WCA scheme aims to encourage cities in close proximity to and dependent on wetlands, especially Wetlands of International Importance, to highlight and strengthen a positive relationship with these valuable ecosystems, for example through increased public awareness of their importance and participation in municipal planning and decision-making.
During the Ramsar COP14 in 2022, the second triennium Wetland City Accreditation Awards Ceremony took place to celebrate the accreditation of 25 new cities (listed below). These cities have joined the already existing 18 accredited Wetland cities that have since been tasked to maintain their accreditation.
Wetland City Network and Roundtable of Wetland City Mayors – sharing best practices among decision makers
To further promote the conservation and wise use of urban and peri-urban wetlands, and to share city-level experiences among city leadership, the Roundtable of Wetland City Mayors first took place in 2019, where a Wetland City Network was established to continue the work of the accreditation scheme and enable cities to achieve more and learn from other Wetland Cities. The 2nd Roundtable of Wetland City Mayors will take place in June 2023, in Amiens, France.
The 2022 accredited cities are:
Sackville was built on/adjacent to saltwater marshes which had been dyked and drained in the 1600s to become freshwater “dykelands”. Since then the Town has undertaken many projects to restore, protect and utilize them, including creating legal restrictions which are supported by laws at all levels of government. The wetlands include the internationally recognized Sackville Waterfowl Park.
Hefei has 118,200 ha of wetland area, with a wetland protection rate of 76%. The city has invested in the protection of the Chao Lake area, protecting 10 wetlands covering a total of 100 square kilometers. This has significantly contributed to aquatic ecosystems, water security and quality, and wildlife habitat – up to 562 wetland plant species and 303 bird species. The City’s strategies include nine wetland education centers, wetland protection volunteers and science popularization to enhance residents’ relationship with the wetlands.
Jining City is known as the “Canal Capital” for its abundant water resources, booming business activities and cultural exchanges. Jining wetlands cover an area of 158,800 ha, with the wetland protection rate reaching 77.38% as a result of the government’s commitment to wetland protection. Nansi Lake and the Grand Canal – designated as a Ramsar site in 2018 – attract millions of migratory birds every year.
Lianping’s rivers, streams, lakes, reservoirs and small wetlands are protected by the City’s strategy of “comprehensive water management, wetlands nourishing the city”, and its adopted model of “small and micro wetlands construction with ecological conservation, pollution control, organic industry, and natural education”, to benefit the lives of communities surrounding the urban wetlands.
Nanchang has a wetland area of 153,000 ha, which provides a major habitat for hundreds of thousands of waterfowl globally, and an important wintering place for Siberian white cranes. The City has protected 68% of its wetlands and restored more than 8,000 ha, enhancing the ecological functions of wetlands, the urban living environment, and the socio-economic development of the city.
Panjin’s wetland covers 249,600 ha, accounting for 60.8% of the whole area. Its wetland protection rate is 54.6%, with 124,000 ha of wetlands restored since 2018 – benefiting the value of rice, river crab, tourism and other wetland industries. Panjin’s coastal wetlands are home to 477 species of wild animals – including 78 species of national key protected wild animals – and a stopover or destination for millions of migratory birds, including the Saunder’s Gull, Red-crowned Crane and Western Pacific Spotted Seal.
In Wuhan the Yangtze River (the third largest river in the world) meets its largest tributary, the Han River. Endowed with 165 lakes and 166 rivers, Wuhan has abundant wetland resources and a wetland rate of 18.9%. Ecological restoration is secured through legislative protection, ecological compensation, conversion of fish ponds to wetlands, restoration of degraded wetlands, and public participation.
Yancheng has two Wetlands of International Importance and one coastal wetland World Natural Heritage Site. By 2021, the protection rate of natural wetlands in the city has reached 62%, and the “Yancheng Yellow Sea Wetland ecological restoration case” is renowned for its global nature protection in densely populated and economically developed areas.
The Belval-en-Argonne municipality joined forces with several nature protection associations (e.g. Birdlife France), to purchase the ponds of Belval-en-Argonne, which were designated a Regional Nature Reserve in July 2012. Major restoration work on the dykes and sluices has been carried out to better manage the water levels, and a large inventory of ponds and amphibians to create awareness of the site’s biodiversity has been created.

Many projects implemented in Al-Chibayish city have contributed to the revival and sustainability of its wetlands. These wetlands support infrastructure and basic services for the local population and economy, in addition to its unique scenery and ecotourism services. The marshes also support a unique cultural heritage that is characterized by its residents and their traditional handicrafts, landscapes and biodiversity – such as buffalo and wild birds.
Izumi City is known as the largest wintering site of cranes in Japan, where more than 10,000 hooded and 2,000-3,000 white-naped cranes migrate every winter. The wintering habitat comprises mainly rice paddies which have been protected by Japanese policies against development. One of the city’s pillars of city planning includes “A city where human happiness and environmental conservation go together”.
Niigata recognizes the multifaceted benefits of wetlands near the city and involves their citizens in protection activities – particularly for fisheries – such as including school children for environmental education. The Niigata community has a relationship with the waterfowl, such as swans, that roost in the wetlands at night and feed in the rice paddies of the city area during the day.
Ifrane is located in the heart of the Atlas Cedar Biosphere Reserve, and considered to be the “ecological capital” of the Kingdom of Morocco. The City is working to conserve its urban wetland ecosystems – Lake Zerrouka, the Aïn Vittel springs and Oued Tizguite – through many national regulatory measures and instruments for the protection of wetlands. With its partners, Ifrane Province is a pioneer in the restoration of wetlands by piloting the “Lake Dayet Aoua restoration project”.
Gochang (Republic of Korea)
There are two Ramsar wetlands in Gochang, both protected under the National Wetlands Protection Act. Gochang has restored the paddy fields since 2017, and restored the brackish water zone between 2016 to 2020. The area is surrounded by ecotourism activities, such as the open market, and educational programs that are creating awareness among the communities of the importance of restoring wetlands.
Seocheon (Republic of Korea)
The Seocheon Getbol wetland reserve – a UNESCO World Natural Heritage Site – is a designated migratory route for migratory birds between East Asia and Oceania, and home to 19 endemic species and three endangered invertebrates, supporting 100 species of waterfowl. The Seocheon County Ordinance operates the Wetlands Protection Committee, a public-private joint organization, to systematically preserve and manage wetlands through monitoring, restoration and waste collection.
Seogwipo (Republic of Korea)
The Mulyeongari Oreum Wetland in Seogwipo City is home to 15 endangered species of living organisms. Ecological specialists and local residents in Seogwipo City perform extensive ecological monitoring on a regular basis to protect the Mulyeongari Oreum Wetland.
The Kigali Wetlands have been threatened by human activities such as agriculture, human settlements, commercial and industrial activities – decreasing their capacity for flood and pollution abatement. In response, the City is implementing strategic ecological rehabilitation solutions such as the Kigali wetland masterplan, which supports the efficient and sustainable management and use of wetlands. As a result, all business activities inside wetlands were evacuated; Nyandungu wetland (121.7ha) was transformed into a recreational eco-park; and a study to rehabilitate five wetlands that cover 480 ha has been conducted to contribute to its Vision 2050 of developing a Green City.
Cape Town (South Africa)
Cape Town is a coastal city with numerous wetlands and is a recognized global biodiversity hotspot. The City aims to mitigate wetland damage through innovative policies and plans, wetland offset projects, best-practice wetland management and restoration, people and conservation programmes, skills development, job creation, plus the Mayor’s priority water quality programme addressing impacts to and rehabilitation of the City’s larger wetlands.
L’Albufera de València is a wetland culturally linked to the community’s heritage, including traditional fishing and rice cultivation. Since the 1970s, Valencia’s City Council has played a fundamental role in the site protection and planning, which has resulted in the lagoon and coastal forest being declared a Natural Park in 1986. In 1982, the Devesa-Albufera Municipal Service was created, responsible for the development of plans and projects for the conservation and restoration of the wetland.
Sri Songkhram District (Thailand)
The Songkhram River has a basin of 6,473.27 km2 and is an important tributary of the Mekong River. About 54.2% of the overall Songkhram Basin may be classified as “wetlands”, which are significant as a capture fishery providing seasonal employment, income and food to thousands of households. Other products are also sourced from the wetlands by local residents (e.g. mushrooms, bamboo shoots, wild vegetables and reeds). The wetlands, declared as a Ramsar site, are protected as a “community forest” on both sides of the Songkhram River, set up by Thailand’s Royal Forest Department.
ICLEI’s role as partner to the Convention
The Independent Advisory Committee (IAC) governs the Wetland City Accreditation Scheme. This committee reviews the Wetland City Accreditation applications from candidate cities and reports its decision to the Standing Committee of the Convention. ICLEI, along the Convention on Wetlands’ International Organization Partners, promotes the Wetland City Accreditation Scheme and local efforts to gain and maintain its branding. Through ICLEI’s city networks and CitiesWithNature platform, it is well positioned to promote the Wetland City Accreditation brand. During the second triennium from 2019 until 2022, ICLEI has been serving as Co-chair of the IAC, 25 more cities were accredited and they received their award during an Award Ceremony at COP14 in Geneva in 2022.
