Can nature save our cities from the global water crisis?

Cities around the world experience water as being either too little, too much, or too dirty, and often usually a combination of the three. Rapid urbanisation, climate change, biodiversity loss and landscape degradation mean that many cities are facing chronic water insecurity. In 2023 alone, two-thirds of the global population experienced water stress, while cities from Cape Town to São Paulo have faced severe droughts over the past decade. Meanwhile, excessive rainfall and poor infrastructure left cities like Nairobi and Jakarta struggling with catastrophic flooding.

The growing urban water crisis

The economic cost of flooding is staggering. According to the multinational professional services firm Aon, urban flooding globally caused USD 105 billion in damages in 2021, disrupting economies, displacing millions, and overwhelming emergency response systems. In 2021, record-breaking floods in Germany and Belgium caused over €46 billion in damages, highlighting the vulnerability of even well-developed urban areas.

Water pollution further exacerbates urban water challenges. 80% of the world’s wastewater is discharged untreated into rivers, lakes, and oceans, contaminating drinking water and harming ecosystems. The UN estimates that polluted water leads to 1.8 million deaths annually, primarily due to waterborne diseases. Additionally, industrial waste and plastic pollution in urban waterways disrupt aquatic life and reduce the availability of clean water for consumption and irrigation.

A direct result of climate change is that the hydrological cycle has changed with flows between physical states (liquid, gas, ice and back) speeded up, resulting in more infrequent, shorter, and more intense precipitation in many parts of the world. Floods and droughts follow each other in close succession, while higher temperatures provide a fertile breeding ground for algal blooms and water-borne diseases.

The water sector globally is underinvested with the recently released World Bank report “Funding a Water-Secure Future: An Assessment of Public Spending” finding that in 2023 just 1.2% of public funding was invested in water infrastructure globally. More concerningly, the report finds that the annual funding shortfall to achieve SDG 6.1 (achieve universal and equitable access to safe and affordable drinking water for all) and SDG 6.2 (achieve access to adequate and equitable sanitation and hygiene for all) is USD 140.8 billion. 

The question is no longer if cities will be affected by water crises, but rather, how can cities adapt for a more water-resilient future?

A nature-based approach to water resilience

Nature-based Solutions (NbS) offer a powerful, cost-effective way for cities to tackle water challenges. Instead of relying solely on expensive grey infrastructure, cities can leverage natural systems to manage water sustainably. NbS investments are also a way of protecting investments in grey infrastructure by reducing the risk of flood damage, siltation, and salinisation. Green roofs, wetlands, urban forests, and permeable surfaces not only reduce flooding and improve water quality but also enhance biodiversity and create healthier urban spaces. For these investments in NbS to be sustainable it is important that they are included in the municipal asset register, listed as an item of grey infrastructure, such as a dam or a wastewater treatment works. Only then will they attract an annual operation and maintenance budget to keep them in the condition whereby they can continue providing service.

However, there is much work to be done at all levels. Investments in urban NbS projects are on the decline and only 37% of the world’s 500 most populous cities have specific strategies in place to sustainably manage and protect nature. A comprehensive study by the World Economic Forum (WEF) Nature Positive: Financing the Transition in Cities released in 2024 shows that from 2018 to 2023 there was a 47% drop in water-related urban nature finance approvals by the major multilateral development banks. Further, the report finds that only 0.3% of global urban infrastructure spending is allocated to NbS and on average less than 10% of total approved project expenditure from MDBs between 2018 and 2023 was directed towards urban nature projects.

For cities looking to take action, the message is clear: Nature is not an obstacle to urban development, it’s the foundation for a sustainable future.

A call to action for cities worldwide

CitiesWithWater webinar series

The CitiesWithWater webinar series, an initiative under the CitiesWithNature platform, will showcase leading examples of how urban areas are integrating NbS into water management strategies and financing their implementation. Examples include Barcelona highlighting its innovative use of urban wetlands and stormwater harvesting to reduce dependence on external water sources. Similarly, Bogotá has restored its high-altitude wetlands, ensuring long-term water security for its residents while preserving critical ecosystems, while Cape Town is developing a large-scale managed aquifer recharge system using a blended finance model developed with support of the World Bank.

A key takeaway from these discussions is that collaboration between city planners, environmentalists, the private sector, and communities is essential.

Inspiring action through visual storytelling

Recognising the power of visual storytelling, the CitiesWithNature International Photography Competition is inviting photographers to capture how nature is shaping urban water resilience. From rain gardens in Melbourne to mangrove restorations in Manila, powerful images are helping to highlight solutions to water being too little, too much or too dirty. The competition not only raises awareness but also inspires decision-makers to invest in sustainable, nature-based water solutions.

The challenges of urban water management are daunting, but cities do not have to tackle them alone. Through global platforms like CitiesWithNature and initiatives like the CitiesWithWater webinar series, cities can learn from one another and implement tested, scalable solutions. Investing in NBS is not just about securing water for today, it’s about ensuring resilience for generations to come.

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.

Ref: WHO

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.

Have you ever heard of a “Blue Flag beach”? Of course you have! The iconic Blue Flag is one of the world’s most recognized voluntary awards for beaches, marinas, and sustainable boating tourism operators. 

We are proud to announce that Blue Flag has joined the global CitiesWithNature partnership initiative! 

Image provided by: Blue Flag

Coastal zones are critical areas, not only to provide livelihoods and recreational opportunities, but because they serve as immensely important buffer areas to sea level rise, deadly floods and storm surges, while also providing essential, safe havens and breeding grounds for many fish species and countless other organisms, plants and animals. Blue Flag, founded by the Foundation for Environmental Education (FEE), will actively work with CitiesWithNature to promote nature conservation activities across its networks.

“We know that we can achieve more together than separately and will strive to make the most of our collaboration as we implement solutions for people and the planet.”

Daniel Schaffer, CEO of the Foundation for Environmental Education

To qualify for the Blue Flag, a series of stringent environmental, educational, safety, and accessibility criteria must be met and maintained. The beach must comply with laws and/or regulations pertaining to issues related to coastal zone planning, environmental management, wastewater management, environmental conservation, and others in order to receive and maintain Blue Flag status.

 

With this awards system, the mission of Blue Flag is to promote sustainability in the tourism sector, through environmental education, environmental protection and other sustainable development practices. As a result of Blue Flag and its partnerships, more than 5,000 beaches, marinas and eco-tourism boats are concretely contributing to the sustainable development goals. Blue Flag also campaigns against disparity, inequality, unemployment, health threats, depletion of natural resources, environmental threats, pollution and general environmental degradation. Find out more about Blue Flag’s efforts to contribute to the Sustainable Development Goals  here. 

 

In addition to its role in maintaining coastal ecosystems, FEE is also a recognized world leader within the fields of Environmental Education and Education for Sustainable Development. Through its three youth-focused educational programs, Eco-Schools, Learning about Forests (LEAF), and Young Reporters for the Environment (YRE), the organization uses a solutions-based pedagogical approach to empower young people to create a more environmentally conscious world. 

 

As an international umbrella organization, FEE has over 100 members in 81 countries and has its Global Secretariat in Copenhagen, Denmark. Through this partnership, CitiesWithNature and Blue Flag will work towards bringing even more unique and tailor-made technical services, reporting mechanisms, capacity-building and funding opportunities – specifically in the field of coastal management – to our collective Blue Flag and CitiesWitNature cities and towns globally. 

“We are so pleased to welcome the highly respected global Blue Flag programme into the CitiesWithNature initiative, demonstrating our shared commitment to work with subnational and local governments in coastal cities to ensure that we live, act and plan with nature. This partnership provides a unique opportunity for urban communities and their governments to rise to the challenge and take ownership of our precious shores, committing to renewed action as part of this important Decade on Ecosystem Restoration.”

Kobie Brand, Deputy Director General of ICLEI

This new partnership comes right on time, with world leaders recognising and adopting an action-oriented Political Declaration to save the ocean from existing and future threats, including marine pollution, harmful fishing practices, biodiversity loss, and acidification at the 2022 UN Oceans Conference in Lisbon – co-hosted by Kenya and Portugal in June this year at the onset of the United Nations Decade of Oceans Science for Sustainable Development (2021-2030).

The UN Ocean Conference, co-hosted by the Governments of Kenya and Portugal, took place between 27 June and 1 July 2022 in Lisbon, Portugal, and culminated in delegates adopting a political declaration titled ‘Our Ocean, Our Future, Our Responsibility’. 

The conference brought together national and local governments, UN agencies, and multiple stakeholders across different sectors to explore and identify solutions aimed at finding major structural transformations and common shared solutions, to be anchored in the SDGs. 

Under the theme ‘Scaling up ocean action based on science and innovation for the implementation of Goal 14: stocktaking, partnerships and solutions’, discussions focused on leveraging interlinkages between Sustainable Development Goal 14 (SDG 14 – Conserve and sustainably use the oceans, seas and marine resources for sustainable development) and other SDGs towards the implementation of the 2030 Agenda for Sustainable Development. Throughout the conference, the linkages between SDG 14 and goals related to clean water and sanitation, poverty, food security, health, women, decent work, climate action, cities, terrestrial ecosystems, and partnerships were emphasized.

Jessie Turner, Director of the International Alliance to Combat Ocean Acidification (OA Alliance) captured the importance of urgent action for oceans: “When talking about climate change impacts on our ocean, we must be clear that while we don’t know everything, we know enough to act. We know enough to begin prioritizing and exploring the key questions that are most important to policy makers, seafood industries and coastal communities. And the good news is…we have lots of existing frameworks across different scales of governance that can be leveraged to take up this work.”

ICLEI – Local Governments for Sustainability and ICLEI’s Cities Biodiversity Center was represented by Kate Strachan – Manager, Climate Change Resilience, ICLEI Africa, and Stefania Romano – Global Coordinator for CitiesWithNature and RegionsWithNature, Recruitment and Advocacy.

During an interactive dialogue titled ‘Leveraging interlinkages between Sustainable Development Goal 14 and other Goals towards the implementation of the 2030 Agenda’, ICLEI emphasized the need for cities to learn from one another and apply these lessons and practices to protect, manage and restore vulnerable urban coastal ecosystems. To achieve this, CitiesWithNature and RegionsWithNature are international partnership initiatives providing a platform to connect local and subnational governments globally with NGOs, experts and communities to act for nature.

By 2025, nearly 6 billion people will live within 200 km of a coastline. Population growth and climate change-related impacts are increasing coastal risks and degrading coastal ecosystems upon which millions depend. Climate change impacts also compound existing pressures, such as pollution from land-based sources, ocean acidification and overfishing. Coastal cities and regions have unique opportunities to mobilize and demonstrate leadership in taking action to protect our ocean and ensure that the ocean and its accompanying coast are sustainably managed.

“It has never been as urgent as it is today to restore damaged ecosystems,” Stefania said. “SDG 14 offers a great opportunity to advance ocean sustainability globally and address current and emerging threats.” The goal is underpinned by targets addressing the conservation and sustainable use of the ocean, seas and marine resources – including coastal zones – and capacity building for ocean governance. In addition, SDG 14 supports the achievement of SDGs related to poverty alleviation, food security, sustainable blue/ocean economy, and climate change.

ICLEI was involved in a number of sessions and played a role in bringing to the forefront the role of subnational governments in ocean governance. As evident during the conference, both national and subnational governments are leading the way, taking domestic and international actions that expand climate-ocean policy and financing for this work.

Organizations and partnership initiatives such as ICLEI, CitiesWithNature and RegionsWithNature can facilitate learning from coastal city leaders, while simultaneously seeking deeper integration across climate, ocean and biodiversity commitments. These efforts will advance actions that address climate change, support food security and sovereignty, and increase resilience of marine ecosystems, economies, and communities.  

Despite the delays in pivotal ocean and climate convenings and benchmarks as a result of Covid-19 restrictions, the UN Oceans conference sparked momentum once again, through the notable outcome of the 2022 UN Oceans Conference – the ‘Our Ocean, Our Future, Our Responsibility’ declaration. 

Matosinhos side-event

Prior to the official Conference, a Special Event on ‘Localizing Ocean Action’ was held in Matosinhos (Porto) on 25 of July, convened by the co-hosts of the 2022 UN Ocean Conference, together with the City of Matosinhos, and organized in collaboration with UN DESA, UN Global Compact, the Climate Champions Team, the Global Taskforce of Local and Regional Governments, ICLEI, Regions4 Sustainable Development, Ocean & Climate Platform (OCP), United Cities and Local Governments (UCLG), Resilient Cities Network, the International Association of Cities & Ports (AIVP) and OECD. The special session highlighted urban-ocean linkages, specifically around marine plastic pollution, blue finance, local community development, human rights-based approaches towards transformation, and SDG 14 and the Post-2020 Global Biodiversity Framework. The special event also covered the role of local and regional governments to engage in global efforts and decisions to protect the ocean and maritime resources. The outcomes from the special event were conveyed during the main UN Ocean Conference.  

ICLEI and the OCP co-organized Local Ocean Action Session 1, titled ‘The clock is ticking: How can coastal cities build resilience and incorporate nature-based solutions to protect local populations?’ This session focused on the importance of investing in innovative sustainable solutions, particularly nature-based ones, to combat the impacts of climate change, such as flooding, coastal erosion and rising sea levels. Speakers were invited to share innovative practices implemented by cities and regions. The panel was moderated by Kate Strachan, while Stefania Romano presented CitiesWithNature and RegionsWithNature as the Convention on Biological Diversity-recognized international partnership initiatives providing a platform and connecting local and subnational governments acting for nature. The side-event resulted in the Municipality of Matosinhos joining CitiesWithNature.

Session key messages included

  • Coastal territories adaptation has to be considered at a larger territorial scale. From megalopolis to secondary cities and small towns, the more vulnerable urban areas have to collaborate at the regional scale to better design sustainable coastal adaptation strategies. It is crucial to reinforce cooperation at every level and encourage a “whole-of-society” approach.
  • Climate coastal adaptation is changing towards a new sustainable paradigm. There is no one-fit-all solution. Managed retreat, nature-based solutions, hard and soft coastal protection, technical innovations, early warning systems, raising awareness, and education are all relevant responses that have to be combined, considering the local context. 
  • Key coastal stakeholders all have to be engaged in the global coastal transition for a sustainable blue economy, a well-adapted coastline and an equitable future. Local decision makers, populations, civil society, ports, tourism sector and privates should all be part of a co-construction process. 
  • Coastal adaptation and resilience has to include societal issues. Many communities have a difficult time securing funds and techniques for equitable coastal resilience. Targeting youth and women in terms of livelihood, coastal adaptation might be an opportunity to reduce poverty and social inequalities.

ICLEI in collaboration with Regions4, the Government of Catalonia, UCLG, and the Global Taskforce of Local and Regional Governments co-organized session 3: ‘Strengthening Cooperation, Building Innovative Governance Approaches to protect the ocean. Finding solutions to the complex and multi-dimensional sustainability challenges faced by coastal areas, which are aggravated by climate change, requires an inclusive and innovative governance approach. Building on the previous sessions that focused on impacts and finance, this session focused on governance as a core condition for the implementation of SDG14. 

Session key messages included

  • Local and regional governments have been leading in developing effective solutions through local public service provision, partnerships and initiatives that include and support fishers, and local populations and their know-how and experience must be harnessed to protect our oceans.
  • Co-management approaches among different spheres of government and actors trigger a culture of collaboration and trust thus enabling an ecosystem-based management. These approaches can in turn permeate to other sectors.
  • The achievement of sustainable small-scale fisheries calls for inclusive and participatory governance arrangements, at all levels. This entails meaningful participation, taking into account and addressing existing power imbalances, strengthening stakeholder organizations, such as small-scale fisheries organizations and supporting dialogue and peer learning.
  • Close collaboration among actors must be backed by scientifically recognized data, all facilitated by impartial elements that ensure accountability and transparent, informed and fair processes.
  • The capacity of local and regional governments in building sustainable management models needs to be strengthened. Particularly, the capacity of SIDS and their cities and regions to respond to global challenges in light of increased ocean and sea degradation.
  • Local and regional governments are willing to join the decision-making table on biodiversity and ecosystem conservation, convening a powerful voice one the global agendas, while promoting opportunities for peer-learning, exchange of experiences and scale-up of effective practices.

Register now for Connective Cities’ session on planning for sustainable infrastructure titled ‘Green infrastructure: Guidance & recommendations for overcoming the implementation gap in cities’. The event will take place online on 8 June 2022 14:00 – 16:00 (CEST).

What exactly is meant with ‘Green Infrastructure’?

The European Commission defines Green Infrastructure as “a strategically planned network of natural and semi-natural areas with other environmental features designed and managed to deliver a wide range of ecosystem services such as water purification, air quality, space for recreation and climate mitigation and adaptation.”

There are already many innovative strategies and practices on local level in place when it comes to sustainable urban planning, urban greening, and land-use as well as ecosystem-based management practices. However, there is also a lack of systematic implementation of urban green infrastructure and underpinning cross-sectoral governance and management arrangements as well as access to these practice-oriented solutions and the relevant contacts.

To this end, Connective Cities and in partnership with NetworkNature is organising this session that focuses on the main barriers of green infrastructure implementation. The session also aims at highlighting best practices and experience of European and international cities in overcoming these barriers as well as introducing the audience to available guidance and resources.  The session showcases the findings of the scientific opinion paper drafted for the German Environment Agency, and a mapping of remaining nature-based solutions knowledge and implementation gaps performed as part of the H2020 project NetworkNature. The session also aims at highlighting best practices and experience of European and international cities in overcoming these barriers as well as introducing the audience to available guidance and resources.

Why should cities commit and take action for nature on the CitiesWithNature Action Platform?

CitiesWithNature Action Platform recognises the critical role cities play in protecting and restoring nature

Visit the Action Platform here

Why do we need nature to make our cities more sustainable and resilient?

  • By 2050, two thirds of people will live in urban areas.
  • People depend on healthy ecosystems for food, livelihoods, health and wellbeing.
  • By integrating nature into our cities, we enhance community resilience to global challenges like climate change, and enable people and biodiversity to thrive.
  • There is a growing urgency for collective and large-scale action to protect the biodiversity in and around cities to prevent irreversible loss and damage to the natural systems we depend on.
  • Now more than ever, we must unite and embrace nature, reconnect communities with nature, and become CitiesWithNature! 

Why are the world’s biodiversity goals important for cities?

  • Through the United Nations Convention on Biological Diversity (UN CBD), countries commit to a new and ambitious blueprint, the post-2020 global biodiversity framework (GBF), to guide actions for protecting nature and its vital contributions to people.     
  • The GBF has a whole-of-government approach and recognizes that cities and subnational governments are key to its successful implementation.
  • In the 2030 Action Targets, the GBF sets out clear targets for urgent actions we must take in the next decade, so that people may live in harmony with nature and thrive.

How can CitiesWithNature help cities to thrive with nature?

What contribution can cities make?

  • Cities are where most people live, where new ideas germinate, where most of the consumption that threatens nature takes place, and where many decisions are made, reaching far beyond the city limits.
  • Local and subnational governments have direct contact with the people who live in their cities, allowing for more concrete and strategic action on the ground.
  • Local and subnational governments have the power to integrate nature into the way cities work.
  • They can do this through policy reform, advocacy, investment, and on-the-ground interventions.
  • They can do this for land use and urban development planning; infrastructure development and maintenance; management of consumption including agriculture, water and industry; resource mobilization; and urban response to disasters and risks – ultimately improving health and wellbeing.
  •  2030 Action Targets, the GBF sets out clear targets for urgent actions we must take in the next decade, so that people may live in harmony with nature and thrive.

What is the Action Platform?

  • The CBD recognizes the CitiesWithNature Action Platform in its Plan of Action on Subnational Governments, Cities and Other Local Authorities for Biodiversity (2021-2030 as the place where cities will monitor and report on their voluntary commitments to national and global biodiversity targets.
  • Through the Action Platform, cities can showcase their actions and plans, understand how they contribute to global nature goals and easily track their achievements.
  • The Action Platform translates the post 2020 global biodiversity framework into commitments that cities and regions are willing to make, taking specific actions under the commitments and setting targets for a particular action most relevant to the city’s local context.
  • It  has 3 action areas that align with the categories of the CBD 2030 Action Targets: to protect and restore nature; use nature sustainably; and develop tools and solutions.
  • , the GBF sets out clear targets for urgent actions we must take in the next decade, so that people may live in harmony with nature and thrive.

How cities can make their mark through the Action Platform

Level 1: Make a COMMITMENT

  • A city can show its commitment to take action on specific topics such as nature areas, recycling and access to parks.     
  • All commitments are voluntary but will contribute towards achieving global and national targets for protecting and restoring nature.
  • After making commitments, cities can move on to the next step: Taking specific actions and setting specific targets aligned with their local and regional context and priorities.

Level 2: Take specific ACTIONS to achieve a commitment

  • After making a particular commitment, a city can identify what actions they will take to achieve it.     
  • For example, after committing to “Protect, connect and restore ecosystems”, a city can specify how it will achieve this by taking actions such as “Increase protected areas” or “Restore degraded areas.”
  • These actions should align with the city’s biodiversity plans, policies and strategic direction, as well as subnational and national biodiversity strategies and action plans. 
  • They should be implemented at the city’s pace, considering capacity and resources.

Level 3: Set specific TARGETS to monitor progress

  • After making a commitment, and identifying the actions to be taken, cities can then set targets to track their progress. 
  • For each action, a city can set a specific target for what it wants to achieve by 2030. For example, “By 2030, protected areas will cover 4% of the city’s jurisdiction.”           
  • For each target, a city must also set a baseline. For example, “Currently protected areas cover 2% of the city’s jurisdiction.”

Linking the three levels of the Action Platform

  • Commitments, actions and targets are the three levels of the Action Platform geared to help you in your journey towards achieving sustainability goals. For example:
  • Commitment: Our city commits to protect, connect and restore ecosystems.     
  • Action: We will achieve this commitment by taking the action of increasing protected areas in our city.      
  • Target: By 2030, protected areas will cover 4% of the city.

Calling all cities to take action!

  • By using the Action Platform, cities can inspire each other and show the world what actions they are taking for nature and people. They can monitor and track their progress, and see how their actions compare with other cities in their country, region or continent. 
  • The Action Platform also helps cities to gather information to feed into their countries’ National Biodiversity Strategies and Action Plans. This helps their countries to achieve national priorities and simplify their reporting to the UN CBD.
  • Join CitiesWithNature and use the Action Platform to unite with other cities around the world – to ensure healthier, happier and safer cities for a nature-positive future.

CitiesWithNature Action Platform recognizes the critical role cities play in protecting and restoring nature

The new CitiesWithNature Action Platform will accelerate bold action for nature by enabling cities to make voluntary commitments that contribute towards achieving global and national biodiversity targets.

By joining CitiesWithNature and using the Action Platform, cities become part of a global community of like-minded frontrunner cities, increasing collective action and cumulative positive impacts for people and the planet. They inspire and prompt other cities to take action, learn from each other, receive international recognition for their contributions and successes, and build the case for scaling up projects and attracting funding for nature.

These commitments also contribute to a global Action Agenda under the United Nations Convention on Biological Diversity (CBD), in support of the forthcoming post-2020 Global Biodiversity Framework. The connection to the Sharm El Sheikh to Kunming Action Agenda for Nature and People elevates commitments from cities and non-state actors to reduce the drivers of biodiversity loss and advance positive socio-economic and ecological outcomes.

Cities and subnational governments are key to the successful implementation of the post-2020 global biodiversity framework, and I applaud our active collaboration in connecting the CitiesWithNature Action Platform as an engagement channel to raise awareness and mobilize cities’ commitments worldwide into the Sharm El Sheikh to Kunming Action Agenda for Nature and People.

We welcome the opening of the CitiesWithNature Action Platform, which is recognized by the Convention on Biological Diversity in the draft Plan of Action on Subnational Governments, Cities and Other Local Authorities for Biodiversity (2021-2030), as the place where cities will monitor and report on their voluntary commitments to national and global biodiversity targets.

Only a whole-of-government approach will ensure the urgent change needed to secure a sustainable future for all!

While the nations of the world gather in Geneva to advance the text for an ambitious and transformative post-2020 Global Biodiversity Framework to safeguard nature, large and small cities around the world are encouraged to share their actions on the CitiesWithNature Action Platform. It is envisaged that this will be just as influential as the climate actions of cities, which have been shared via global climate reporting platforms for many years.

The CitiesWithNature Action Platform is aligned with the 2030 Action Targets in the post-2020 Global Biodiversity Framework, and makes it easy for cities to share their commitments, set their own targets, track their progress, and see how their actions compare with other cities in their country, and globally. It also helps cities gather information on how they contribute to their countries’ National Biodiversity Strategies and Action Plans, and can support national reporting to the UN CBD.

With more than 80% of global Gross Domestic Product (GDP) generated in cities and more than half of global GDP estimated to be dependent on nature, it is clear that cities have a critical role to play in ensuring nature is restored and protected. Local and subnational governments have the power to integrate nature into the way cities work, through policy reform, advocacy and on-the-ground interventions. Topics covered by the Action Platform include everything from nature-based solutions, ecosystem restoration and conservation, to biodiversity mainstreaming, financing and circular economy.

By joining CitiesWithNature and using the Action Platform, cities across the world can commit ambitious actions that contribute to national and global biodiversity and nature goals, and easily track their achievements individually and collectively.

It is fitting that the Action Platform is opening to coincide with Earth Hour, as a catalyst for urgent change to shape our future,

Human-induced climate change is causing dangerous and widespread disruption in nature and affecting the lives of billions of people around the world, despite efforts to reduce the risks. People and ecosystems least able to cope are being hardest hit, said scientists in the latest Intergovernmental Panel on Climate Change (IPCC) report, released on 28 February.

Cities: Hotspots of impacts and risks, but also a crucial part of the solution

The report provides a detailed assessment of climate change impacts, risks and adaptation in cities, where more than half the world’s population lives. People’s health, lives and livelihoods, as well as property and critical infrastructure, including energy and transportation systems, are being increasingly adversely affected by hazards from heatwaves, storms, drought and flooding as well as slow-onset changes, including sea level rise.

Together, growing urbanization and climate change create complex risks, especially for those cities that already experience poorly planned urban growth, high levels of poverty and unemployment, and a lack of basic services.

Cities also provide opportunities for climate action.

Green buildings, reliable supplies of clean water and renewable energy, and sustainable transport systems that connect urban and rural areas can all lead to a more inclusive, fairer society.

~ Debra Roberts, co-chair of the scientist working group Tweet

The headline statement about urban areas from the report is the following:

Interactions between changing urban form, exposure and vulnerability can create climate change-induced risks and losses for cities and settlements. However, the global trend of urbanisation also offers a critical opportunity in the near-term, to advance climate resilient development (high confidence). Integrated, inclusive planning and investment in everyday decision-making about urban infrastructure, including social, ecological and grey/physical infrastructures, can significantly increase the adaptive capacity of urban and rural settlements. Equitable outcomes contribute to multiple benefits for health and well-being and ecosystem services, including for Indigenous Peoples, marginalised and vulnerable communities (high confidence). Climate resilient development in urban areas also supports adaptive capacity in more rural places through maintaining peri-urban supply chains of goods and services and financial flows (medium confidence). Coastal cities and settlements play an especially important role in advancing climate resilient development (high confidence).

Cities and settlements are crucial for delivering urgent climate action. The concentration and interconnection of people, infrastructure and assets within and across cities and into rural areas creates both risks and solutions at global scale.

Climate change has altered marine, terrestrial and freshwater ecosystems all around the world (very high confidence). Climate change has caused local species losses, increases in disease (high confidence), and mass mortality events of plants and animals (very high confidence), resulting in the first climate driven extinctions (medium confidence), ecosystem restructuring, increases in areas burned by wildfire (high confidence), and declines in key ecosystem services (high confidence). Climate-driven impacts on ecosystems have caused measurable economic and livelihood losses and altered cultural practices and recreational activities around the world (high confidence).
