46th International Cities Forum 2023
„Adapting Cities to the Effects of Climate Change and Avoiding Waste to conserve our Resources“
Saturday, June 17
Every year, delegations from the partner and befriended cities are invited to Kiel Week to discuss a particular municipal topic at the International Cities Forum. The event therefore has high potential for the international work of the state capital Kiel.
What it's all about in 2023
This year’s International City Forum is addressing two key municipal challenges: on the one hand, it is looking at adapting cities to the effects resulting from climate change, and on the other, avoiding waste to protect our resources.
In addition to climate protection, the topic of adapting to climate change is increasingly coming into focus. Cities and local authorities around the world are clearly feeling the effects of climate change:
phenomena such as heat and persistent drought, heavy rainfall, severe thunderstorms, high winds, storm surges and rising sea levels are already significant risks for urban residents, municipal infrastructure and urban nature.
The scenarios on possible climatic developments by the International Panel on Climate Change (IPCC) suggest that these developments will intensify considerably and that the risks will continue to increase.
Cities therefore urgently need to continue with and further develop targeted and holistic adaptation measures to protect people, infrastructures, as well as the environment and nature.
Conserving resources and preventing waste are also key current challenges for cities and local authorities: around the globe, the use of natural resources exceeds the regenerative capacity on earth.
The consequence of this is a shortage of resources on the planet. Due to the high consumption of resources, for example, more than 45 million tonnes of household waste are produced each year in Germany alone.
But more and more cities – including Kiel – are fighting against the throwaway trend and joining the zero waste movement: they are committed to stopping the tidal wave of waste.
With the help of the 5 R's – Refuse, Reduce, Reuse, Recycle, Rot – zero waste aims to change consumption habits and keep recyclable materials in a cycle so that no resources are wasted in the form of rubbish. A comprehensive zero waste concept has been created for Kiel for this purpose.
The City Forum aims to highlight different aspects of these two topics – adaptation to climate change and zero waste. To do so, different groups of people – such as representatives from science, civil society, politics and administration – are involved in the City Forum.
Three parallel thematic workshops are at the heart of the event, in which the participating cities will discuss opportunities and challenges as well as lessons learned from tried and tested approaches based on two to three practical examples.
All participants have the opportunity to select one workshop.
Workshops I and II will be offered in German and English, consecutive translations will be provided in addition by whispering interpreters.
Workshop III will be held in English only.
are part of a framework programme consisting of a keynote speech, a dialogue discussion, the presentation of the workshop results and a concluding panel discussion. The attached agenda provides a detailed schedule of the International City Forum.

Kiel bereitet seine Verkehrswende vor. Das Öffentliche Nahverkehrsystem wird eine deutliche Aufwertung erfahren.
Für die Landeshauptstadt Kiel ist das Thema Mobilität 2022 von besonderem Interesse. Bereits 2017 hatte Kiel gemeinsam mit den umliegenden Kreisen Rendsburg-Eckernförde und Plön einen „Masterplan Mobilität“ verabschiedet. Einer der zentralen Punkte in diesem Handlungskonzept ist neben dem Ausbau des Fahrradnetzes auch die Entwicklung eines tragfähigen innerstädtischen ÖPNV-Netzes. Im kommenden Jahr soll die Entscheidung darüber fallen, wie der Stadtverkehr Kiels in Zukunft aussehen soll. Aktuell erarbeiten die Verkehrsplaner*innen eine Trassenstudie, die die beiden Alternativen – Schnellbusse (BRT) oder Stadtbahn (Tram) – in ihren Vor- und Nachteilen gegenüberstellt. Die Studie soll Ende 2022 abgeschlossen sein und eine Entscheidungsgrundlage für die Kieler Ratsversammlung bilden. Eine Diskussion mit unseren internationalen Partnerstädten über deren Mobilitätskonzepte für die Zukunft ist somit für Kiel im kommenden Jahr besonders wertvoll.
Ziel des Städteforums 2022 soll es daher sein, mit den Partnerstädten über die unterschiedlichen Aspekte von urbaner Mobilität und die Herausforderungen der Mobilitätswende in einen Austausch zu kommen. Nach einem einführenden Impulsvortrag der Mobilitätsexpertin Katja Diehl sowie einem Dialoggespräch zwischen Oberbürgermeister Dr. Ulf Kämpfer und Jana Kühl, Professorin für Radmanagement an der Ostfalia Universität, wird es Workshops zu vier verschiedenen Aspekten von Mobilität geben:
- Stärkung des emissionsarmen Öffentlichen Personennahverkehrs (ÖPNV)
- Ausbau von Fuß- und Radverkehr
- Digitalisierung und Mobilitätswende
- Mobilität rund ums Wasser
Abgerundet wird die Veranstaltung durch eine kurze Podiumsdiskussion, die auch Vertreter*innen der Zivilgesellschaft mit einbeziehen soll. Als Querschnittsthema soll dabei immer mitgedacht und diskutiert werden, wie die städtische Bevölkerung mitgenommen und für die Mobilitätswende begeistert werden kann. Der Austausch und die internationale Kooperation mit Kiels Partnerstädten kann bei der Entwicklung von Lösungsansätzen für die Herausforderungen der Mobilitätswende wichtige Impulse geben.
Cities in Cimate Change
Cities will be affected by the consequences of climate change. The talk deals with future sea-level rise and its impacts for coastal cities as well as their specific vulnerability.
It gives an overview on potential ways to adapt to coastal flooding by also presenting regional examples and points out the challenges communities and cities might face when adapting to climate change.
Finally, it gives examples of climate services and an insight on how the field of climate communication can improve those services.
Agenda & Workshops
The three workshops are part of a supporting program consisting of expert input and a concluding panel discussion.
All participants have the opportunity to choose one workshop. Workshop I and II will be held in German and English, Workshop III only in English. Other languages are supported through consecutive translation.

Climate change is leading to more intense and more frequent precipitation. The term heavy rainfall describes the phenomenon of large amounts of rain falling within a very short time in a mostly localised area.
The existing municipal drainage systems such as sewers, pumping stations, retention basins and water bodies are not designed for these volumes of precipitation and reach their capacity limits during heavy rainfall events: the risk of flooding increases.
Heavy rainfall events can either affect entire districts or only certain streets. Large-scale flooding may occur or only isolated underground areas such as cellars and underground garages may be affected.
Despite modern climate and weather data collection, it is not possible to predict with certainty whether, when and to what extent a municipality will be affected by a heavy rain event.
Flooding poses a major challenge for local communities, including from rivers and as a result of rising sea levels in coastal cities. Flood management for surface waters attempts to prevent the flooding of settlement areas by means of sheet piling retaining walls and dykes, among other things.
In the case of extremely heavy rainfall, however, the issue is how to harmlessly drain precipitation from the settlement area and increasingly also the question of rainwater management.
In order to bring together all actors from urban and landscape planning, water management, fire brigade, traffic and road planning, first of all the political decision-makers in a local authority must recognise heavy rainfall as a potential risk, put it on the political agenda and tackle it progressively.
This is what happened in Kiel. As a supplement to the previous planning and activities of the civil engineering department, a hazard and risk analysis was carried out as a precautionary measure.
Comprehensive heavy rainfall risk maps have been produced for the city region, showing where water flows on the surface in the event of a heavy rainfall event and where there is a risk of flooding.
The city administration uses these maps, among other things, as a supplement in drainage planning, in disaster control and in urban planning in the construction and green space sectors.
- To what extent have extreme weather events (specifically: increased flood risks due to heavy rainfall) increased in recent years and how do these already affect your city/municipality today?
- What risk-reducing (e.g. technical, planning, constructional) measures are already being implemented or planned in your city/municipality?
- What conflicts of objectives could potentially arise as a result? How can local / city administrations and political decision-makers deal with this?
- What is the basic responsibility of cities/municipalities in mitigating and adapting to extreme weather events? Where does local action reach its limits?
- What are the limits within which adaptations can be made by means of structural measures?

Climate change is causing weather patterns to change and weather conditions to last longer in some cases. This in turn favours long-lasting heat waves and urban heat islands.
Especially in cities, this leads to persistent heat exposure: the asphalt shimmers, the air barely moves between the tall buildings, temperatures continue to rise on the upper floors of flats, and even at night cities no longer cool down.
The temperature difference between the countryside and the city can be up to 10 degrees Celsius. One reason for this heat is the materials used in the city: concrete, glass or metal surfaces store a lot of heat and seal a large part of the surface.
This means that rainwater runs off quickly and less water evaporates, making it harder for the city to cool down. Buildings and streets absorb the sun's rays, store the energy and release the heat back into the surrounding air. Air-conditioning systems or car exhaust fumes make cities sweat even more due to their lost heat.
These temperature changes can have a strong impact on the well-being and health of the population: heat can put enough strain on the cardiovascular system to the point of death. Sunny years are also associated with high UV radiation exposure, which raises the risk of UV-related health problems like skin cancer.
UV radiation also promotes chemical processes in the atmosphere that increase air pollution. High air temperatures and strong solar radiation also heat up rivers, lakes and seas and promote the growth of harmful microorganisms in the water. In addition, a gradual rise in temperature can favour the spread of disease-causing or allergenic plants and animals.
Older people aged 65 and over, people in need of care, pregnant women, the homeless, asthmatics, people who work outdoors and small children are at especially high risk from heat.
This is why it is the task of local authorities and cities to develop measures to protect these people in particular from negative health effects and to create an overall healthier urban climate for all residents. Kiel's administration is currently in the process of developing a heat action plan for the city.
The challenges must be addressed at different levels. These include, for example, awareness-raising and educational measures, as well as the establishment of early warning systems. To cool cities down, useful measures such as planting green roofs and facades, using light-coloured paving stones, reducing car traffic in the city and preserving and creating fresh air corridors can also be helpful.
One essential and multifunctional measure is expanding green spaces and enhancing them for use as recreational areas: green inner-city spaces close to residential areas contribute significantly to reducing water runoff through their lawns and tree cover, and help cool the surrounding area through their evaporative surface.
Green connections between the outskirts and the city centre also encourage fresh air into the city. In this way, green spaces provide relaxing places in the city and a less stressful urban climate, especially during hot spells.
Maintaining green spaces and enhancing them for use as recreational areas, as well as unsealing paved surfaces and creating new, generously sized green oases in the city are decisive ways to keep the urban population healthy. They can also help minimise traffic in the surrounding area.
Sustainable solutions must be found for the competing land demands of living, working and recreation in the urban regions that consider the health and quality of life of the population.
A landscape plan is a suitable instrument for providing the city with recreationally relevant open spaces on a large scale and in a planned manner.
Green areas and trees can be secured and further developed in specific locations using an open space balance which takes into account the accessibility and recreational suitability of the areas as well as the building density, among other assessment criteria.
- What measures have you already taken, planned or discussed in your city/municipality to improve the urban climate?
- How can specific (vulnerable) population groups be better reached in order to protect them effectively? Is "leave no one behind" a viable paradigm to address the impacts of climate change in a socially adequate way?
- To what extent can negative health effects of climate change already be observed today on the population and especially vulnerable groups in your city/municipality?
- What conflicts of objectives could potentially arise as a result? How can local and city administrations and political decision-makers deal with this?

Two billion tonnes - that's how much waste is produced worldwide every year. Germany's annual packaging waste generation is far above the EU average.
This much too high volume of rubbish not only wastes the precious resources of our earth, but also endangers the environment, the health of animals and humans, and promotes the warming of our planet.
However, more and more cities, organisations and companies want to do something about this negative development and have joined the international zero waste movement.
Zero waste aims to conserve all resources or their materials through responsible production and conscious consumption, and to reuse products, packaging and materials.
According to the zero waste principle, no resources are burned and no waste is discharged into the land, water or air that could harm the environment or human health.
With the goal of preventing waste, zero waste not only aims to protect natural resources, but also contributes to climate protection by reducing greenhouse gas emissions. Both the production and the disposal of products and materials involve a high energy input.
If unnecessary products are dispensed with from the outset, CO2 emissions can be avoided along the entire supply chain – from raw material extraction, processing and product manufacture to transport.
Preventing waste and reusing products can also save large amounts of greenhouse gases by using less energy for the recycling, and recovery and disposal processes that would otherwise be necessary.
The City of Kiel was the first German city to join the "Zero Waste Europe" network and to develop a zero waste concept in a participatory process, in which more than 100 waste prevention measures are defined and clear targets are set for 2035 and 2050.
In the past two and a half years, the first measures have already been successfully implemented and many more have been started.
These include, for example, financial support for the use of cloth nappies, the comprehensive and mandatory introduction of reusable systems at public events such as Kieler Woche, the installation of drinking water dispensers at schools or a city-wide competition for the promotion of resource-conserving everyday life.
Since February 2023, Kiel is now the first city in Germany to be officially certified as a “Zero Waste Certified City”.
- What options and necessities for waste prevention and resource protection exist at local/municipal level as a contribution to climate protection?
- What advantages can arise for citizens and local/city administrations and how can appropriate incentives be set?
- How can appropriate measures be implemented effectively and successfully in cooperation with civil society, the private sector and the broad public?
- What challenges and potential conflicts of objectives could arise as a result?
