Connecting citizens to nature: The strategy behind Yokohama’s waterside campaign

What is Yokohama Waterside Oshi-katsu?

“Oshi-katsu,” which refers to the act of supporting one’s favorite people or characters such as idols, artists, or anime characters, has become a powerful cultural trend in Japan. The City of Yokohama is utilizing this concept to promote its waterside areas under the campaign “Yokohama Waterside Oshi-katsu”, which offers a variety of content, including the citizen-led survey “Yokohama Waterside Report,” as well as blogs and social media posts by “Donburako”, the mascot character. These fun-oriented activities incorporate a casual and playful approach, aiming to encourage citizens to visit local watersides, discover their charm, and ultimately foster active engagement with the local water environment.

The Yokohama Waterside Report

The Yokohama Waterside Report, the core content of the Yokohama Waterside Oshi-katsu, is a citizen‑led survey that assesses watersides using the Water Environment Soundness Index. The Index evaluates watersides across five indexes: natural state, richness in plants and animals, water clarity, pleasant waterside environment, and regional water culture. By assessing waterside areas based on these five indexes, participants can observe them from multiple perspectives. By gaining a deeper understanding of the unique characteristics of each waterside, the hope is that people will discover their own “oshi” (favorites). Anyone can participate in the Yokohama Waterside Report. Forms and manuals are available on the website and it is also possible to participate through the app. The city compiles the submitted reports and publishes them annually.

Voices of participants

Participants expressed surprise at the clarity of the water and the abundance of aquatic life, with some showing interest in joining future waterside conservation activities. These responses suggest that many citizens are not fully aware of the actual conditions of watersides in their local areas, and that providing opportunities to raise awareness can serve as a motivator for participation in waterside conservation activities.

Meet Donburako, the campaign mascot

The initiative features an original character, “Donburako,” a mysterious, lovable creature travelling along rivers and coastal waters in a bowl-shaped boat. The word “donburako” is an onomatopoeic expression describing something gently floating down a river in a Japanese folktale. Combined with its adorable appearance, the name evokes a sense of familiarity. In recent years, the use of characters has become a popular trend to create emotional connections and make ideas more approachable. Donburako adds a friendly and playful touch to the campaign through its blog and social media posts, attracting people’s interest.

Background of the initiative

Yokohama achieved significant improvements in water quality after the severe pollution period of the 1950s to 1970s, and today it is home to beautiful watersides. However, surveys have revealed that citizens’ satisfaction with the water environment is not very high, indicating that approaches focused mainly on water quality are no longer sufficient. At the same time, Japan’s Basic Environment Plan identifies well-being as a top objective. Considering these circumstances, the goal for the city is to enhance citizens’ satisfaction with waterside areas and related well-being through the current water environment policy. To this end, the city decided to implement an initiative to help citizens recognize the attractiveness of waterside areas.

Meanwhile, Yokohama has many citizen groups working on the conservation and restoration of waterside environments, and their activities have produced tangible results, such as the return of fireflies and dragonflies to local watersides. The city examined why these groups are engaged in such efforts and concluded that their motivation comes from a deep connection and care for their local watersides.

Yokohama believe that in order to encourage more people to have such a connection with waterside areas, the city should prioritize collaboration with community groups already familiar with these areas and with local schools that are actively engaged in ESD. In addition, to reach audiences who are not currently interested, the city planned to use “enjoyment” as a gateway to spark their interest in waterside activities.

Through these initiatives, Yokohama aims to help citizen groups and students discover diverse attractions and characteristics of waterside environments that they may not have noticed before, further deepening their appreciation. At the same time, for citizens who lack interest in watersides, the city devised ways to spark curiosity by connecting the ideas of “fun” and “liking” to oshi-katsu, a form of Japanese culture centered on supporting one’s favorite interests.

How does this initiative work?

The governance of this initiative is structured as a networked system led by the City of Yokohama, which provides overall coordination. Any citizen can participate in the Yokohama Waterside Oshi‑katsu, which is centered on the Yokohama Waterside Report, and surveys may also be conducted jointly by the city, citizen groups, and schools.

Regarding how responsibilities are shared, citizens conduct the surveys, while the city is responsible for compiling and publishing the results. When surveys are conducted collaboratively with schools or citizen groups, responsibilities are usually shared as follows: schools handle classroom activities and student supervision; citizen groups provide interpretive guidance on the history and characteristics of the local waterside; and the city is responsible for explaining the survey procedures.

Additionally, to broaden the reach of the Yokohama Waterside Oshi‑katsu, the city participates in various events. In these cases, the event organizers are responsible for overall management, while the city takes charge of operating booths and related activities. Collaboration generally starts with the city reaching out to stakeholders and remaining open to their proposals.

The value and impact of the initiative

By creating opportunities for people to discover the charm of watersides, the initiative fosters a deep connection and care for watersides, leading to citizens’ proactive involvement in environmental conservation. The project thus contributes to sustainable urban development and improved well-being.

This year, International Day for Biodiversity shines a direct spotlight on the role of local and subnational government leaders in the global effort to protect nature. With more than half of the world’s population living in cities, the intersection of urban expansion and natural ecosystems is where the future of global biodiversity is being decided. The world increasingly recognizes that cities and regions are critical partners in meeting national targets and the global biodiversity goals.

Turning nature-positive ambition into a reality means local action must be visible. CitiesWithNature and RegionsWithNature have more than 1,300 actions and 700+ active commitments recorded on the Action Platforms, but to truly have an impact, the global community needs every city and region to rise to the challenge.

This October, global leaders will gather at the Convention on Biological Diversity COP 17 in Yerevan, Armenia, to review progress and accelerate action. All achievements will be celebrated at CBD COP 17 and the 9th Summit for Subnational Governments and Cities on 24 October 2026, an official COP parallel event co-hosted by ICLEI, the CBD Secretariat, Regions4 and the COP host country.

We invite all cities and regions to join CitiesWithNature and RegionsWithNature to ensure all subnational actions for nature are counted towards achieving the Kunming-Montreal Global Biodiversity Targets.
Acting Locally for Global Impact: An Open Letter to Mayors and Governors

Astrid Schomaker

Executive Secretary of the Secretariat for the Convention on Biological Diversity

Montreal, 14 May 2026

Dear Mayors and Governors,

You are leading action where it matters most — in the communities where more than half of the world’s people live, learn, work, and innovate. Cities and subnational governments are at the forefront of efforts to build more sustainable, resilient, and inclusive societies, while also helping to reconnect people with biodiversity.

As pressures on ecosystems continue to grow, local leadership has become increasingly important to help ensure healthy environments, resilient economies, and a better quality of life for present and future generations.

This year, the International Day for Biological Diversity is an ode to those “acting locally for global impact”. This letter is an acknowledgement of the crucial role of subnational governments, cities, and local authorities in bringing about a much-needed global surge of action to halt and reverse biodiversity loss. It is also a renewed invitation to use the Kunming-Montreal Global Biodiversity Framework (KMGBF) and its 23 targets as a blueprint for local action.

December 2022 marked a landmark moment: Parties to the Convention on Biological Diversity (CBD) adopted a renewed and more ambitious decision to engage subnational governments, cities and local authorities in accelerating implementation of the Kunming Montreal Global Biodiversity Framework (KMGBF), the world’s blueprint for halting and reversing biodiversity loss.

That decision also recognised CitiesWithNature and RegionsWithNature as platforms for subnational governments and cities to report their commitments and actions in support of KMGBF targets and National Biodiversity Strategies and Action Plans (NBSAPs).

The Secretariat of the Convention on Biological Diversity welcomes the surge of local leadership and action. The journey toward a nature-positive world, where people and nature thrive together, begins in our communities. The choices that cities and regions make daily ripple outward and can drive global transformation.

Increasingly, we hear inspiring stories of cities, towns, provinces and states restoring habitats, protecting species, greening infrastructure, investing in a resilient future and engaging communities in stewardship. Together, these thousands of local acts add up to real and measurable progress.

The CBD Secretariat has been collaborating with ICLEI Cities Biodiversity Center (CBC) to ensure that commitments reported on CitiesWithNature and RegionsWithNature are seamlessly reflected in the CBD Clearing-House Mechanism, which tracks implementation progress. This means that local action is counted and amplified at the national and global levels.

Reports on local action are also critical for monitoring and evaluation as shaped by Parties to the Convention. COP 17, which will take place in Yerevan in October 2026, will see the first global review of collective progress in the implementation of the KMGBF.

One of the key outcomes being sought is an agreement on how to accelerate action to close gaps. Subnational governments, cities and local authorities must be part of that whole-of government and whole-of-society endeavour.

We are now halfway through in the KMGBF implementation race. It is abundantly clear that we must do more and that we must act faster. Slow, incremental change is no longer a choice. The much-needed acceleration can also stem from increased awareness and commitment from local actors, in line with the three pillars of the IDB 2026 campaign: Look and Learn, Connect and Act, and Share.

The journey toward living in harmony with nature—the vision adopted within the KMGBF— begins with steps taken by you and your constituents, including communities and local businesses.

We look forward to celebrating your achievements at the 9th Summit for Subnational Governments and Cities, an official parallel event co-hosted by ICLEI, the CBD Secretariat, Regions4 and Armenia at the 2026 United Nations Biodiversity Conference in Yerevan. In the meantime, every commitment and every action matter, for nature and all people.

In the movement to protect our planet’s biodiversity, the front lines aren’t just in remote rainforests or distant oceans — they are in our backyards, our city parks, and our urban waterways. As the world works toward the ambitious goals of the Kunming-Montreal Global Biodiversity Framework (KMGBF), we recognize that global targets cannot be met without local action.

The CitiesWithNature and RegionsWithNature Action Platforms are central to this effort. These platforms are officially recognized as commitment and reporting platforms for subnational governments, cities and other local authorities in the Convention on Biological Diversity (CBD) Decision 15/12. As the only non-state actor platforms with a recognized pathway for subnational governments to contribute information towards the KMGBF, they allow subnational governments to showcase their plans, track commitments, and understand exactly how their local biodiversity efforts contribute to the health of the entire planet. Local actions and data feed directly into national dashboards within the CBD system, contributing to the global review of collective progress. In short, your city’s actions don’t stop at your borders. The Action Platforms serve as a vital link between high-level international policy and on-the-ground implementation.

Local and regional governments are on the frontlines of biodiversity and climate action. They manage urban wetlands, coastlines and forests, they implement nature-based solutions, and they drive community-led initiatives. We contribute directly to global biodiversity goals. Today, let’s remember that when urban action takes place, the world moves closer to living in harmony with nature.

From policy to pavement: Inspiring urban transformation

Across the globe, local and subnational governments are proving that urban development doesn’t have to come at the expense of nature. By integrating green and blue spaces into the urban fabric, these cities and regions are enhancing human well-being while restoring lost ecosystems.

Here are a few ways cities and regions are taking action to safeguard biodiversity:

Paris

France

Aligned with its Bioclimatic Local Urban Plan, Paris aims to increase accessible green space from 8.6m2 to 10m2 per inhabitant by 2040. This transition is anchored by the 2024 “300 hectares open to the public” program, which aims to make 300 hectares of green spaces accessible to city dwellers. These efforts ensure nature is a functional, everyday component enhancing health and well-being and urban climate resilience.

Curitiba

Brazil

Long considered a pioneer in sustainable planning,  Curitiba integrates nature in its public health strategy. The city uses “Linear Parks” along riverbanks to prevent flooding and provide equitable leisure areas, while the Municipal Nursery acts as an “open-air laboratory” to educate citizens on the importance of the Atlantic Forest biome. Currently, the city has 10,294.19 hectares of urban green and blue spaces accessible to 99.94% of the city’s population.

Nansha District, Guangzhou

China

In a masterclass of ecological restoration, Nansha District has revitalised idle spaces into ecologically rich zones. This includes the transformation of abandoned quarries into the Phoenix Lake series of parks, as well as repurposing under-bridge spaces into parks to ensure that citizens “see green from every window and a park at every door”.

Cape Town

South Africa

Cape Town is focusing on becoming a “water-sensitive city” by cleaning up its vleis (wetlands) and rivers. A unique aspect of this water and community resilience strategy is the fostering of “Friends Groups”, in which community-led partnerships give local residents a direct say in how their green spaces are managed and developed.

Quebec

Canada

At the provincial level, Quebec adopted its “2030 Nature Plan” in 2024. This comprehensive strategy explicitly links biodiversity conservation with human health, prioritizing “biodiversity-friendly access” and ensuring that First Nations and Inuit communities are partners in the sustainable management of natural environments.

Why should cities and regions join the movement?

The Kunming-Montreal Global Biodiversity Framework has 23 action-oriented global targets for urgent action over the decade to 2030. Target 12 of the KMGBF focuses on enhancing green and blue spaces and urban planning for human well-being. This depends on a collective effort by cities and regions across the globe. By joining the CitiesWithNature and RegionsWithNature initiative and using the Action Platforms, local and subnational governments don’t just make a commitment to their community, but also to their country and the world. Every green corridor created, every wetland restored, every policy adopted gets counted, reported, and recognised globally. In joining, they also gain:

By joining the CitiesWithNature and RegionsWithNature initiative and using the Action Platforms, local and subnational governments gain:

Recognition: Official status as a contributor to global biodiversity goals.

Tools: Frameworks to track and report progress accurately.

Community: Access to a global network of peers sharing nature-first solutions.

This is your chance to say: We are one of the world’s CitiesWithNature (or RegionsWithNature) — and to have that commitment counted where it matters most.

The CitiesWithWater initiative has placed water firmly on the urban sustainability agenda. Through a webinar series and an international photography competition, CitiesWithWater is raising the voice of cities and learning how they can and should act now to safeguard water systems, human well-being and ecosystems.

As climate change intensifies and urbanisation accelerates, cities around the world are increasingly defined by water. In some cases they have too little, sometimes too much, or sometimes water that’s too dirty.

In the recent webinar titled “Too Much“, hosted in collaboration with the World Water Council, city leaders and technical experts explored how urban areas are preparing for or recovering from floods, storms, sea-level rise and the cascading impacts of climate change. This second installment in the CitiesWithWater series followed the success of the first (“Too Little”) and sets the stage for the upcoming webinar, “Too Dirty”, which will delve into water pollution and the urgent need to protect downstream ecosystems and coastal waters.

Lessons from the frontlines of flood resilience

The “Too Much” webinar (18 June 2025) highlighted that flood-related disasters have increased by 134% since 2000 (WMO, 2021), a statistic that no city can afford to ignore. Panellists from cities including Kumamoto (Japan), Lusaka (Zambia), Ningbo (China), and Larissa (Greece) shared powerful case studies on how their municipalities are adapting to flood risks.

  • Kumamoto has invested in nature-based solutions such as forest conservation and paddy field water storage, alongside digital tools like VR training to prepare citizens for evacuation.

     

  • Lusaka, where 70% of residents live in informal settlements, is tackling both flood risk and disease outbreaks (e.g., cholera) through community-based infrastructure projects, water point upgrades and employment programmes to clean and unblock drains.

     

  • Ningbo has built a seven-pronged urban water strategy, including intelligent monitoring and rain gardens, to successfully weather major typhoons with minimal impact.

     

  • Larissa, still recovering from Storm Daniel in 2023, highlighted how fragmented governance and lack of infrastructure left the city vulnerable and why resilient planning and institutional cooperation are essential.
These stories reinforce a key takeaway: there is no single stand-alone solution. Urban water resilience requires multi-layered, collaborative and forward-looking solutions, blending engineered infrastructure with ecosystem restoration and active community engagement.

From catchment to coast: The broader picture

What happens upstream doesn’t stay upstream. With the UN Ocean Conference (UNOC) recently reaffirming the vital links between terrestrial and marine systems, CitiesWithWater is also working to bridge the gap between urban water governance and coastal health. Dirty or excessive water from cities — be it stormwater, untreated sewage, or plastic waste — flows downstream, posing major threats to fragile estuaries, coral reefs and fisheries.

In the upcoming “Too Dirty” webinar, these linkages will be explored more deeply. How can cities protect downstream ecosystems from pollution while safeguarding human health and livelihoods? What does it take to reduce nutrient runoff, manage industrial discharge and treat wastewater effectively in dense urban settings?

According to UNEP, 80% of marine pollution comes from land-based sources, much of it through poorly managed urban water systems. Without effective urban catchment management, the oceans will continue to bear the brunt of our inaction.

Wetlands in the city: Nature’s green infrastructure

With the Convention on Wetlands COP15 fast approaching in July 2025 in Victoria Falls, Zimbabwe, CitiesWithWater is also drawing attention to the vital role of urban wetlands. These ecosystems, often overlooked in city planning, act as natural sponges that absorb floodwaters, filter pollutants and recharge aquifers.

Wetlands also serve as critical habitat for biodiversity, cooling spaces for urban residents and buffers against sea-level rise and coastal storms. Yet urban expansion continues to degrade or destroy them. Between 1970 and 2015, 35% of the world’s wetlands were lost (Ramsar Global Wetland Outlook, 2018), and many that remain are under pressure from pollution, encroachment and climate change.

Cities that invest in wetland protection and restoration — like Cape Town’s rehabilitation of the Zandvlei Estuary or Kolkata’s use of its East Kolkata Wetlands for natural sewage treatment — are leading the way in reintegrating nature into urban water systems.

As cities prepare for the Wetlands COP, this is the moment to embed wetlands into climate adaptation strategies and urban planning frameworks. The cost of inaction is rising fast in terms of infrastructure damage and ecological collapse.

Why urban water systems matter and why they’re at risk

Urban water systems are not just pipes and pumps. They are the veins and arteries of a living city to sustain health, enable growth and connect communities. Yet they are under serious threat:

The challenges are multiple and formidable, but the opportunity is commensurately large. With the right investment, policy coherence and public engagement, urban water systems can be pathways of resilience. Well-managed urban water systems can cool cities, protect coasts and support biodiversity, not only within urban areas but also for the surrounding catchment on which they are dependent.
From risk to resilience Water — too much, too little, or too dirty — is no longer a peripheral issue. It is central to the survival and success of cities in the 21st century and forms the blue thread through the three Rio Conventions on climate change, biodiversity and desertification and land degradation. CitiesWithWater is helping bring that message to life by hearing directly from city officials how they are rising to the challenge and turning threats into opportunities.

About the author:
Erik Hirschfeld is a well-known Swedish birder fortunate to live in Malmö. He is the author of several books, including The World’s Rarest Birds (2013) covering global bird conservation and Fåglarnas Malmö (2011), covering Malmö’s birds and their interaction with humans. He has served on bird record committees in Sweden, Jordan and the United Arab Emirates, and has been involved in several scientific expeditions, especially in the Middle East. Fifteen years ago he founded Vilda Malmö, initially a lose network of nature guides, in order to highlight Malmö’s natural environment to its residents. Today he spends his birding time between being an active bird bander, studying migration of seabirds, and running Scandinavia’s largest bird tour company, AviFauna. He frequently gives illustrated talks on birds to both beginners and professionals, and guides people interested in birds for Vilda Malmö.

Few northern European cities can match Malmö when it comes to urban birdwatching. With over 320 species recorded, Malmö proudly tops the list of Swedish cities for avian biodiversity. And it’s not by chance. There are some brilliant reasons why this coastal city is such a magnet for birds.
As a proud member of CitiesWithNature, Malmö is deeply committed to enhancing and preserving its urban ecosystems through sustainable planning and community engagement.

A crossroads for migration

Perched at the southern tip of the Scandinavian Peninsula, Malmö offers migratory birds a convenient shortcut across the water to Denmark and mainland Europe. Much like the famed Falsterbo, just 30 km down the coast, Malmö is perfectly positioned along a major migratory route. When on the move, many landbirds avoid vast bodies of water and instead funnel through areas with shorter crossings. Add the iconic Öresund Bridge into the mix, and you’ve got a ready-made flight path. On windy days, birds of prey can often be seen using the bridge as a navigational aid during their spring and autumn journeys.

But geography alone doesn’t explain Malmö’s birding success. Migrants won’t stop unless there’s a good reason to. That’s where Malmö’s clever city planning and habitat diversity come into play. The city is a patchwork of microhabitats catering to a dazzling variety of birds with different needs.

Habitat hotspots and urban adaptations

Take the coastline, for instance. Stretching out in a mix of sandy, muddy, and rocky areas, it serves up a smorgasbord of habitats for wading birds, perfect for sanderlings, bar-tailed godwits, and purple sandpipers. In the harbour, boulders placed as wave-breakers become life-saving shelters for tired migrant passerines hiding from hungry sparrowhawks. Seabirds following the east-west coast are often seen rerouting dramatically to avoid land, providing unforgettable spectacles for those positioned at just the right windy vantage point. In fact, gannets now winter offshore in large numbers, mingling with massive flocks of cormorants. Two species of albatross have even made surprise appearances here, an astonishing rarity in these parts, and sooty shearwaters from New Zealand have become almost annual guests.

One of Malmö’s most productive hotspots is the stretch along Ribersborg Beach. Here, seaweed is cleared to please beachgoers and then dumped near a hedge by Lagunen harbour. That unassuming pile teems with insect life and sits beside a dense alley of trees, offering both food and shelter to weary warblers. Come migration season, that compost pile becomes a lifeline. It’s also the site of an ongoing bird banding project, and when the seaweed dries out, it’s used to fertilise Malmö’s public lawns, an example of ecology in action.

Inland, a series of freshwater ponds offers safe nesting and feeding areas to mute swans, little grebes, and the red-necked grebe, a striking species whose springtime courtship dances can be enjoyed up close, even without binoculars. These ponds give Malmö residents front-row seats to one of nature’s most theatrical performances.

Birds in the parks and cemeteries

Every spring, a headline act unfolds in the city. Ravens nest in an old shipbuilding crane beside a waterfront residential zone, an urban first in Sweden. Unlike the domesticated Tower of London ravens, these are wild birds, voluntarily choosing Malmö’s industrial relics as breeding grounds.

The city’s beloved parks are no less impressive. Hammars Park, with its wild undergrowth, attracts songbirds like blackcaps, wood warblers, and goldfinches. Pildammsparken, with its elegant promenade and wide pond, plays host to ducks, gulls, and breeding great crested grebes showing off their curious greeting displays in spring. It’s a favourite among preschoolers, grandparents, and birders alike, offering easy access and rich wildlife. Slottsparken, meanwhile, offers a blend of trees and water that appeals to both breeders and migrants.

In late morning, gulls descend from the coast to bathe in the parks’ freshwaters. Tufted ducks and common gulls, with nesting grounds as far away as Siberia, make Malmö their winter base. Come late February, they’re joined by the first migrant lesser black-backed gulls, newly arrived from central and eastern Africa. Meanwhile, black-headed gulls spend the colder months here after journeys from Finland and the Baltics. Banded individuals, some as old as 30, have revealed fascinating life histories stretching across multiple cities and countries. The combination of being raised and spending the winter in highly urbanized habitats seems to be favorable to longevity.

St Pauli Cemetery, oriented north to south, is another seasonal hotspot, especially in spring. Here, you might glimpse the cryptic wryneck or the elusive ring ouzel, more commonly found in the remote fjells of summer. Redstarts regularly nest here too, making the cemeteries a true urban oasis.

Rooftop nesters and winter guests

Even Malmö’s high-rises play a part. Districts like Västra Hamnen, Dockan, and Limhamns Sjöstad resemble mountainous terrain to birds like the black redstart, which now echo their melodic calls through Malmö’s urban canyons. Some individuals even winter here, finding refuge in the evergreen ivy on buildings near the central station, alongside European robins.

The charismatic oystercatcher also makes its urban presence felt. Arriving in late February, they roost in flocks on jetties used by swimmers in summer before fanning out to nest on flat rooftops. Common gulls, meanwhile, often share these rooftops, while house martins and common swifts each have their architectural preferences. Clay nests on high buildings suit the martins, while the swifts prefer roof tiles on villas in Malmö’s western suburbs.

And let’s not forget the barnacle geese. Once Arctic-bound migrants, they now breed in Malmö in huge numbers, a mix of introduced birds and natural colonists. In May, local geese look skyward as their distant cousins pass overhead in dramatic, noisy formations, en route between the Low Countries and their Novaya Zemlya breeding grounds. Some Malmö-born geese have even been spotted in the Arctic, and vice versa.

Oystercatchers

Of course, the benefits of this biodiversity aren’t just for the birds. Access to urban nature is known to boost human well-being, and Malmö makes it easy to connect with the wild. Through the Vilda Malmö (Wild Malmö) program, residents can join free expert-led tours covering birds, bats, trees, marine life, and more, kept to small, intimate groups. For those who prefer to look for urban wildlife on their own, there are information signs placed around the city, with photos or drawings of the local fauna.

Malmö’s love of birds runs deep. Even its bird alert app, usually the domain of avid birders, has over 1,000 subscribers, proving that in this city, the skies above are just as captivating as the streets below.

With World Health Day coming up on the 7th of April, we reflect on how cities are more than concrete and skyscrapers – they are homes to millions seeking healthier, happier lives. By bringing nature back into the heart of urban living and fostering communities that thrive mentally and physically, cities can reshape how people connect with their environment.

The importance of nature connectedness

Throughout history, humans have been deeply connected to nature, relying on it for survival, from the air we breathe to the water we drink, to the food we grow. Nature connectedness explores how we think, feel, and interact with the natural world. Feeling close to nature fosters a sense of belonging, encourages us to seek it out, and enhances our happiness when immersed in it. Without nature, there is no “us.” When we feel very close to nature, we recognise ourselves as part of the natural world and value our relationship with it. 

Contact with nature has many benefits; studies demonstrate that people with high nature connectedness tend to have frequent, long-term contact with nature, spend more time outdoors, exhibit ecologically aware attitudes and behaviours, and are happier. Moreover, exposure to urban nature promotes pleasant moods. Research shows that people who are more connected with nature are usually happier in life since nature can generate positive emotions, including calmness, joy, and creativity (Nisbet & Zelenski, 2011). A population survey revealed that a strong connection to nature significantly boosts well-being, with its impact on life satisfaction being four times greater than socioeconomic status (Martin, White, Hunt, et. al., 2020).

By spending more time enjoying and connecting with nature, our society’s motivation to protect it might increase, ultimately supporting a cycle of benefits for people and the environment. The journey to connect with nature begins with an introspection of our ways of being in, engaging with, and relating to nature. The Nature Connection Handbook provides 5 pathways to nature connection:

Sense: explore and experience nature through all senses 

Beauty: seek and appreciate the beauty of the natural world 

Emotion: notice and welcome the feelings nature inspire

Meaning: celebrate and share nature’s events and stores

Compassion: help and care for nature

This approach aligns with GBF Target 12 which aims to ensure biodiversity-inclusive urban planning to improve human health and wellbeing.

The impact of nature connectedness on health and happiness

Numerous studies have shown that access to green spaces in cities has profound effects on human health:

Mental health benefits

Spending just two hours a week in nature significantly reduces stress, anxiety, and depression, according to research published in Nature (2019). Exposure to green environments has been shown to lower cortisol levels, significantly reducing the body’s primary stress hormone.

Physical health improvements

Urban greenery encourages physical activity such as walking, jogging, or cycling, helping combat lifestyle diseases like obesity, diabetes, and cardiovascular conditions. The presence of trees and parks is linked to improved air quality, reducing respiratory problems.

Community connection

Shared green spaces foster social cohesion and a sense of belonging, helping to reduce loneliness and isolation, especially among vulnerable groups like the elderly.

Examples of urban nature in action

Barcelona’s superblocks: The city has transformed car-dominated streets into vibrant pedestrian-friendly zones filled with greenery. This initiative has reduced air pollution by 25% in some areas and increased physical activity among residents. See Barcelona’s CitiesWithNature profile here.

High line, New York City: This elevated linear park repurposed an old railway track into a lush green corridor, attracting over 8 million visitors annually while improving mental well-being and local biodiversity. See New York’s CitiesWithNature here.

Tokyo’s green walls and rooftops: The city incentivizes green roofs and vertical gardens, providing mental relief and lowering urban heat islands, which improves overall livability.

Singapore’s therapeutic gardens: Designed specifically for mental well-being, these gardens are used for stress relief and dementia care, showcasing how tailored green spaces can address public health needs.

Del Carmen’s Mangrove Management Program: Demonstrated how environmental restoration can enhance both ecosystems and human health. The city created a science-backed plan that not only conserved mangroves but also improved the lives of locals. Key strategies included policy changes, environmental education, and raising awareness about the link between nature and well-being.

Utrecht’s NbS for urban resilience and wellbeing: The city promotes healthy urban living through a green and blue framework that integrates climate regulation, noise reduction, recreation, and cleaner air. The city’s tree policy addresses environmental challenges while providing green spaces for recreation, contributing to the physical and mental well-being of residents.

Examples of urban nature in action

Human health and well-being are inextricably linked to the health of the natural world. International scientific assessments, including the IPCC and IPBES, emphasize that achieving sustainability requires halting and reversing biodiversity loss. The IPBES further claims that sustainable goals will not be achieved without a ‘transformative change’ including an increase in ‘awareness of connectivity in the environmental crisis and new norms regarding interactions between humans and nature’. 

It’s now widely acknowledged that we are facing a triple planetary crisis caused by humans’ use of Earth’s resources. Large-scale political, economical, social and cultural shifts are needed to meet the challenges we face in addressing climate change, biodiversity loss, and pollution emergencies. The principle of nature connection can be applied at subnational and local levels to foster nature-positive change, enabling communities to lead meaningful, healthy, and happy lives.

Cities and regions with strong ties to nature can drive sustainable development by aligning the Global Biodiversity Framework (GBF) Targets and the Sustainable Development Goals (SDGs). Prioritizing long-term interventions and collective action to protect urban biodiversity is essential to prevent irreversible harm to the natural systems we rely on.

How can your city take action?

Create green infrastructure

Expand urban parks, plant trees, and invest in green roofs and walls.

Prioritize accessibility

Ensure green spaces are safe, inclusive, and accessible to all, particularly in underserved communities.

Promote nature-based activities

Encourage outdoor recreation, gardening programs, and eco-education to foster deeper connections with nature.

Engage the community

Collaborate with local groups, schools, and businesses to co-create spaces that reflect community needs.

By embedding nature into the fabric of cities, we can nurture happier, healthier communities while addressing global challenges like climate change and biodiversity loss. Cities can transform into thriving ecosystems that serve both the planet and people.

While wetland ecosystems are increasingly being recognized as highly valuable natural assets that provide a wide range of benefits to urban communities, the services they provide are under immense pressure due to rapid urban expansion and human activity. Cities are uniquely positioned to drive local action to protect our wetlands.

Below are five key action areas for cities to mobilize urban communities for wetlands:

1

Incorporate wetland conservation into urban planning and policy

Integrate wetland management goals into municipal development plans, zoning regulations, and climate resilience strategies.

Advocate for wetlands as critical infrastructure in disaster risk management, emphasizing their role in flood mitigation, erosion control, and urban cooling.

Allocate funding for wetland restoration and maintenance as part of city budgets.

2

Promote the role of wetlands in water resource management

Highlight wetlands’ function as natural water filters, improving water quality for drinking and sanitation.

Educate communities about the importance of wetlands in regulating stream flow, preventing floods, and mitigating droughts.

Encourage partnerships between cities and water utilities to protect wetlands as vital water supply sources.

Quote

In the weeks to come, and during our meeting in Rome this February, I will work alongside Parties to build the trust and consensus needed to achieve Peace with Nature, ensuring that the goals and targets of the Kunming-Montreal Global Biodiversity Framework (KMGBF) translate into tangible action. Securing adequate and predictable financing will be central to our efforts, enabling transformative change for biodiversity while ensuring benefits for communities and ecosystems alike.

– said H.E. Susana Muhamad, Minister of Environment and Sustainable Development of Colombia and President of COP16.

3

Foster public engagement and education

Organize events such as guided wetland tours, birdwatching activities, and clean-up drives to connect urban communities with local wetlands.

Collaborate with schools and universities to use wetlands as outdoor classrooms for environmental education.

Celebrate World Wetlands Day by showcasing wetlands’ cultural, recreational, and ecological value through art exhibitions, storytelling sessions, and public campaigns.

4

Leverage wetlands for climate action and biodiversity

Showcase wetlands’ role in carbon storage and their contributions to achieving climate targets at city and regional levels.

Promote the restoration of urban wetlands as natural climate buffers that reduce the impacts of extreme weather events.

Highlight their role in preserving biodiversity by creating habitat corridors that link urban green spaces and facilitate species migration.

5

Promote sustainable livelihoods and economic opportunities

Encourage eco-tourism and recreational activities like boating, fishing, and wetland safaris to generate local employment.

Support community-based initiatives in wetland restoration, creating jobs and fostering skills in conservation and sustainable resource use.

Showcase the agricultural and economic benefits of wetlands, such as fisheries, fertile soils, and natural resources, as integral to urban food security and poverty reduction.

Opinion piece by Gareth Presch, CEO, World Health Innovation Summit

Climate change is the single biggest health threat facing humanity. The impacts are already harming health through air pollution, disease, extreme weather events, forced displacement, food insecurity and pressures on mental health. Every year, environmental factors take the lives of around 13 million people. Over 90% of people breathe unhealthy levels of air pollution, largely resulting from burning fossil fuels driving climate change. This is a major problem, especially in urban areas. In 2018, air pollution from fossil fuels caused $2.9 trillion in health and economic costs, about $8 billion a day.

Nature and Health Opportunities

The potential of urban green and blue spaces to generate better health and well-being is clear. Countries around the world are adopting Green Social Prescribing. Green social prescribing is the practice of supporting people to engage in nature-based interventions and activities to improve their mental and physical health. Green social prescribing includes both what is known as green and blue activities. These could include local walking schemes, community gardening projects, conservation volunteering, green gyms, open water swimming or arts and cultural activities which take place outdoors. These activities may be ‘prescribed’ by link workers (and other trusted professionals) alongside other forms of support, for example, referrals to support housing or finances – based on the needs and circumstances of each individual (Global Social Prescribing Alliance).

There are numerous known benefits associated with increased exposure to urban nature. This includes health and well-being benefits, such as:

Physical health

e.g. directly, through reduced air pollution and cooling effects, or indirectly, through increased opportunities for physical activity

Mental health and well-being

e.g. stress relief or reducing harms such as noise

Social, cultural and spiritual benefits

e.g. support of urban nature for social contact and cohesion

Education, heritage and creativity

Finland is leading the way with clean cities and towns based on the recent  2023 World Air Quality Report by IQAir. Indeed, the towns of Sodankylä, Utsjoki and Kuusamo in Finland came out as being the least polluted in the world compared with more than 7,800 different places world wide. The concentrations of small particles in the air were measured in 134 different countries and regions in 2023. According to the report, only seven countries fell below the air quality recommendations set by the World Health Organization (WHO) for the concentration of fine particles. According to the organization, the annual average value of small particles in the air should be less than 5 micrograms per cubic meter. In addition to Finland, Estonia, Iceland, Australia, New Zealand, Mauritius and Grenada fell below the limit. In a comparison of over a hundred capital cities, Helsinki ranked in the top ten in terms of air quality, but even fewer fine particles were measured in the air of the capital cities of Estonia, Iceland, Australia and New Zealand, for example. The most polluted air was in Bangladesh, Pakistan and India. The most polluted capital cities were Delhi in India and Dhaka in Bangladesh.

Ninety-nine percent of the world’s population breathes air that does not meet the limit values ​​set by the WHO and can be harmful to health and air pollution causes seven million premature deaths every year.

With 55% of the world’s population living in urban areas and an additional 52.5 billion urban residents expected in the next 30 years, and with 65% of SDG targets being relevant to cities, it’s no surprise the battle for sustainable development will be won or lost in cities

Ref: UN Habitat

A healthy, thriving natural environment is vital for creating resilient urban places. Cities were on the frontline of the COVID-19 pandemic. The UN’s Report on COVID-19 in an Urban World (2020) noted that 90% of reported cases at that time were in urban areas. While urban density was found not in itself to be a decisive factor in the transmission of the virus,  inequality, inadequate housing, strained health systems, inadequate water and sanitation services and pollution made certain urban areas vulnerable. The pandemic calls for a renewed emphasis on a just and green urban transition, and a renewed focus on addressing inequalities in cities and by promoting nature in cities we can see benefits for citizens.

The climate crisis urgently calls to accelerate the shift towards renewable sources of energy. The way cities are planned and managed has a profound impact on energy demand which impacts our health and nature. Compact, well-planned and managed cities, with non-motorised mobility options, green public spaces and natural cooling/temperature regulation measures tend to have below national levels of energy consumption. These transitions will support our health and well-being.

Financing Nature and Health

As health becomes far more important in determining investment we understand that when health is compromised so is our economic growth. At the Annual Investment  Global Conference 2023 (ref: AIM Report) in Abu Dhabi last year I ran a workshop for the World Association of Investment and Promotional Agencies highlighting the opportunities to invest wisely in health and wellbeing which would deliver long-term economic returns. This was followed up by the COP28 declaration “Healthy Planet, Healthy People” which calls on the health/public sector to support the SDGs with a 1% commitment from the sector’s pension funds (WHS – not for profit fund).  We’re now seeing these new models of healthcare that are focused on the environment and nature ultimately preventing disease while supporting economic growth (New WHIS ESG – Health, Climate Place Based Impact Model). As a result, new opportunities are emerging through partnership working – the establishment of Ecogreen Green Capital (African Focused – Great Green Wall of Africa Foundation) at COP28 and a new fund with the Commonwealth Pacific Climate Fund that will support the Commonwealth’s Small Island Development States for example. 

We must plan and manage our cities in a way that simultaneously accelerates the achievement of SDGs and responds to global megatrends.

Cities must be healthy, sustainable and future-ready with nature at the heart of our plans.

The UN 2023 Water Conference – formally known as the 2023 Conference for the Midterm Comprehensive Review of Implementation of the UN Decade for Action on Water and Sanitation (2018-2028) – took place in New York, from 22-24 March 2023, and was co-hosted by Tajikistan and the Netherlands, with the UN Department for Economic and Social Affairs (UN DESA) as Secretariat. To catalyze action, the Conference sought voluntary commitments from Parties to the Water Action Agenda, to urgently scale up action to address the water and sanitation crisis and ensure equitable access to water and sanitation for all (Sustainable Development Goal 6).

“This is more than a conference on water. It is a conference on today’s world seen from the perspective of its most important resource.”

– UN Secretary-General Antonio Guterres

The Conference managed to generate more than 700 commitments aimed at driving transformation towards a water-secure world, which now form part of the Water Action Agenda, representing the global community’s resolve to address the water challenges through a more coordinated and results-driven approach.

CitiesWithNature and RegionsWithNature side-event

On 24 March, ICLEI through CitiesWithNature and RegionsWithNature, convened an online side-event as part of the conference titled, “CitiesWithNature and RegionsWithNature: Connecting Water and Nature to accelerate local and regional resilience”. The side-event took place in line with the UN Water 2030 Conference which was held in New York with the aim of accelerating action towards the achievement of SDG6.

The aim of this session was to: connect the agendas of water and nature for accelerated local and regional action, building momentum towards the achievement of SDG 6 & 11; provide a platform for cities and regions to connect and share best practices and lessons learnt on water and nature; and promote local and regional resilience actions from leading CitiesWithNature and RegionsWithNature representatives.

To this end, the session, moderated by Stefania Romano – Global Coordinator, CitiesWithNature and RegionsWithNature – showcased examples of the interconnections between biodiversity and water and of different biodiversity management issues and/or challenges which are relevant to the water agenda. These cases, summarized below, were presented by CitiesWithNature cities and RegionsWithNature regions and speakers from Regions4 and other subnational governments – as CitiesWithNature and RegionsWithNature are important platforms for showcasing best practices and case studies that can be scaled out to other cities and regions.

The sustainable management of the littoral zone of Lake Saint-Pierre in Quebec

Caroline Daguet

Conservation Biologist, Ministry of the Environment, Fight against Climate Change, Fauna and Parks

Government of Quebec

 

The littoral zone of Saint Pierre is located in the St Lawrence river in Quebec Province, in Canada. The site is a wetland of importance and both classified as a Ramsar site and UNESCO Biosphere Reserve. The fertile land has historically been used for corn, and more recently soybean, agriculture which has resulted in drainage of the river, habitat loss, shore erosion, siltation, pollutant leaching as well as invasive alien species taking over. Given the extent of the threat to some species, a moratorium was placed on sport and commercial fishing of the yellow perch (Perca flavescens) in 2012.

The sustainable management project of the Lake Saint-Pierre littoral zone is aimed at establishing sustainable agriculture to protect the lake’s ecosystem. The project has led to the development of a floodplain intervention strategy that fosters sustainable and adapted agricultural practices while maintaining the fragile ecosystem of the lake and supporting the restoration of priority sites.

The success of the project can be attributed to the inclusion and collaboration between academia and government ministries and a commitment to involving farmers from the beginning of the project. The project not only focused on crop, soil and water studies, but also included wildlife research and monitoring projects focusing particularly on fish, birds and insects. In addition, the project focused on the governance of the ecosystem – concluding that it is critical to involve regional and local government authorities and indigenous communities in the process.

This case study forms part of the Regions4 database and can be viewed on the RegionsWithNature platform. Quebec has been involved in the database since its launch in 2016 and has been contributing to knowledge-sharing and learning from other subnational governments. Quebec is also a founding member of RegionsWithNature, officially launched in Montréal in Québec at the CBD COP15 in 2022.

Co-management maritime board of the Litoral del Baix Empordà

The Litoral Baix Empordà is a special protected marine area and site of community importance located in Costa Brava, a coastal region of Catalonia in north-eastern Spain. To facilitate co-management of the Litoral del Baix Empordà, the Government of Catalonia formed a board to create a permanent space of participation where proposals can be debated and concretized to improve the management and organization of maritime uses and activities in the area.

The governance model is particularly focused on making these uses and activities more compatible with the area’s natural heritage. Specifically, through stakeholder engagement, the model aims to ensure the conservation and improvement of the natural, cultural and landscape heritage of the area to both safeguard its socioeconomic activity and protect its cultural heritage.

The success of this model has been its bottom-up approach with stakeholders, such as the scientific community, civil society, government administrations, and all critical stakeholders from the blue economy sector. This has created a safe and trustworthy environment that has enabled addressing common problems and discrepancies, ultimately benefiting the protected area. As a result, environmental management has shifted from maintenance and prevention to an Action Plan that is collaboratively designed. Best practices based on this co-management project is also available on the Regions4 database and the RegionsWithNature website.

Water in San Antonio, Texas

Julia Murphy

Deputy Chief Sustainability Officer

City of San Antonio Office of Sustainability

 

San Antonio is a CitiesWithNature pioneer city located in Texas state, USA. As a coastal state, Texas is surrounded by water, but its inland cities experience significant water shortages. Moreover, the Texas Water Board’s projections show that the state’s water supply will decline by 18% between 2020 and 2070. One of the main causes of this decline is the depletion of aquifers from pumping for industrial use, occurring alongside land-use change as a result of agriculture and ranching.

Another concern for water supply across the state is population increase, which is expected to rise to 73% between 2020 and 2070. This will be exacerbated under future climate change, as the state’s already hot climate becomes even hotter, and the City of San Antonio in particular will experience reduced rainfall, more frequent and longer droughts, and reduced water and food security.

Beyond needing drinking water and water for household use, this resource is also of economic importance, given that the San Antonio River is a tourist attraction, with 11.5 million people visiting the San Antonio River Walk annually, providing 31,000 local jobs. San Antonians understand the value of water and its conservation has become entrenched in the city’s culture. Conservation – water that is not used – has been considered a water supply source since 1993.

However, water conservation is contingent on access to open land and the space required for rainfall to replenish aquifers. Since nearly 95% of land in Texas is privately owned, the regional and city governments have had to work closely with landowners to protect their land for water conservation through the Texas Agricultural Land Trust.

For the past 20 years, San Antonians have been voting to tax themselves through sales tax initiatives to conserve open land on usually privately owned land over the main aquifer to protect the water source. Water conservation is further achieved through education, incentives, and reasonable regulation. Read more about the statewide investment into water conservation that will be voted on later in 2023, here.

Towards water resilience in the City of Johannesburg, South Africa

Ernita van Wyk

Senior Professional Officer: Social-ecological Systems 

ICLEI Africa

 

Johannesburg is the biggest city in South Africa and also the economic hub of the country. As a result of the long-term decline of water sources in South Africa’s cities, and projected future climate change impacts, the City of Johannesburg has responded to its current water challenges by investing in two tools: The City of Johannesburg water security strategy (city-wide); and the City of Johannesburg pilot catchment management plan (smaller scale).

The COJ water security strategy

A water secure Johannesburg, as per the UN Water definition, would mean: The City of Johannesburg will have the capacity to safeguard sustainable access to adequate quantities of acceptable quality water for sustaining livelihoods, human well-being and socio-economic development and preserving ecosystems.

To achieve this, the City government co-produced a strategy with relevant stakeholders to secure water supply; manage water demand and losses; ensure access to safe, reliable and equitable water services; promote resilient, liveable and sustainable urban water environment; manage the water system’s knowledge and data; nurture a water conscious society; and achieve coordinated good water governance. A working group was created under each theme, which has culminated in 67 actions for the City to take. A key part of the strategy’s approach has been to identify how different municipalities and sectors work with the same water source, to ensure effective cross-sectoral collaboration based on an integrated approach to water management.

The COJ pilot catchment management plan (Jukskei River)

The aim of this plan was to develop a tool that promotes integrated catchment planning and management practices, linking various catchment aspects in an integrated manner, at the sub-catchment scale. This includes integrating land use, river health and stormwater management for Johannesburg’s Jukskei River catchment. The Jukskei River catchment experiences similar issues to other urban catchments, including: a demand for settlement that leads to encroachment into river courses; drought; increased flooding; pollution; aging infrastructure; degrading open spaces; poor amenity value; and downstream obligations, given that the Jukskei catchment is located relatively upstream. 

The catchment management plan was based on the “water-sensitive city” paradigm, which states that municipal water services are provided against the backdrop of challenging environmental impacts. In response, the plan used a hydrological model to guide extensive stakeholder engagement. Through this process the City realized the significant opportunity for rainwater harvesting and the necessity to start making the catchment area more “spongy” through nature-based solutions – to improve the replenishment of aquifers but also to reduce flooding. Lessons learned and best practices can be found in this CitiesWithNature Catchment Management in Your City Guide, which was launched in this UN Water conference side-event. 

The side-event concluded around the topic of advocacy for water – a universally understood rallying point for mobilizing actions, particularly when climate change is not accepted as a point of advocacy. The panel also emphasized the need for a stronger connection between water and ecosystems, and connecting that with human health.

UN Biodiversity COP15 and Water

Water conservation is included in the newly adopted Kunming-Montreal Global Biodiversity Framework (GBF), for example, Target 3 calls for the effective conservation and management of at least 30% of terrestrial and inland water, especially areas of particular importance for biodiversity and ecosystem functions and services, and Target 2 calls for the restoration of 30% of degraded terrestrial, inland water, and coastal to enhance biodiversity and ecosystem functions and services, ecological integrity and connectivity by 2030. 

Additionally, Target 12, which is specifically aimed as cities, calls for significant increases in the area and quality and connectivity of, access to, and benefits from green and blue spaces (referring to water bodies such as wetlands, rivers, mangroves etc) in urban and densely populated areas sustainably, by mainstreaming the conservation and sustainable use of biodiversity, and ensure biodiversity-inclusive urban planning, enhancing native biodiversity, ecological connectivity and integrity, and improving human health and well-being and connection to nature and contributing to inclusive and sustainable urbanization and the provision of ecosystem functions and services. 

Water targets on the CitiesWithNature Action Platform

The CitiesWithNature Action Platform provides a platform where cities can make their commitments for nature (as referenced in Plan of Action action area 7) and set local  targets to contribute to the GBF targets within the framework of the National Biodiversity Strategy and Action Plan of their country (NBSAP). The Action Platform is aligned with the 2030 Kunming-Montreal Global Biodiversity Framework targets, and provide several options for taking action and making commitments at the local level that relate to water such as “Restore and/or rehabilitate terrestrial, freshwater and coastal ecosystems”; or “Reduce water pollution by biocides and excess nutrients from domestic and industrial sources to protect ecosystems and people’s health.”
