Connective Cities at the 19th Federal Congress on German National Urban Development Policy

From 14 to 16 September 2026, the 19th Federal Congress on National Urban Development Policy will take place in Cologne. The theme is “Act together, act faster, think further: shaping cities for everyone”. This event will bring together stakeholders from local governments, politics, public administration, academia and civil society to discuss innovative approaches to sustainable, resilient and forward-looking urban development.

For the first time this year, Connective Cities will have a stand at the event run by the Service Agency Communities in One World (SKEW). The congress offers an excellent opportunity to raise the profile of the international city network and its services for facilitating professional exchanges between local authorities. We will be focusing on discussions with local authority experts from the fields of urban development, mobility, climate adaptation and sustainable transformation.

At the SKEW stand, we particularly want to show experts what Connective Cities has to offer and discuss potential opportunities for participation and cooperation. We will also present selected examples of good practice from the relevant specialist areas, as well as the Connective Cities Media Centre as a knowledge platform. We warmly invite network members attending the Federal Congress to take this opportunity to speak to the team at the stand. We look forward to exchanging ideas, making new contacts, and generating new impetus for municipal development cooperation.

How Can Municipalities Cope with the Heat?

Heat affects us all. It is one of the world’s fastest-growing and deadliest climate risks.

However, we are not powerless against it. Municipalities around the world are developing and sharing comprehensive strategies. These range from heat action plans and green and blue infrastructure planning to smart rainwater management, the use of AI, and the creation of digital twins for risk-informed crisis management.

Naturally, municipalities have also been tackling this crucial topic within the Connective Cities framework. We’ve put together a selection of examples from the Connective Cities context along with additional resources for you.

Heat in the City – The Connective Cities Deep Dive Learning Process
From 2023-2025, six municipalities joined forces to analyse the impact of heatwaves and heat islands, and developed solutions tailored to local conditions.

Insight Session Urban Tiny Forests in drought-affected Regions

On July 8th, 2026, Connective Cities hold an online Insight Session to explore ways, by which urban forests can be cultivated under difficult climate conditions. Attempts to do so are notoriously difficult in dry regions with high temperatures and low precipitation, where the usage of scarce water resources has to be distributed between (urban) populations, local businesses, agriculture and industry. Planting and watering urban trees is regularly considered secondary under such circumstances, leading to unsuccessful attempts of urban afforestation due to a lack of financial support and maintenance work. The Insight Session was joined by 34 participants from 13 countries, representing a broad range of municipalities from Africa and the Middle East.

Over the past decades, the Miyawaki-method of planting tiny forests has become an outstanding success story around the globe. In this technique developed by Japanese botanist Akira Miyawaki, a small dense forest is made from native trees and plants. The specifically dense way of planting a miscellany of indigenous plants accelerate the growth of flora and fauna, so that after around five years, micro forests may already be entirely self-sustaining. The forests improve air quality, reduce heat and bring back lost biodiversity, thereby stabilizing ecosystems and countering the environmental degradation as a result of the climate crisis. A videographic overview of the Miyawaki-Method can be found here.

Stefan Scharfe, speaking on behalf of Miya-Forest, a forest-planting/educating/researching NGO based in Eberswalde, Germany explained the success of the Miyawaki method through the instance, that planting trees is usually broadly accepted among a range of actors such as urban populations, housing providers and local administrations. However, the participatory approach of planting urban micro forests must be facilitated through a small group of core actors who take ownership of the project. Especially a thorough soil study can significantly increase the chances of the micro forests to become self-sustainable after an initial, intense phase of watering and caring.

Coming from the highly urbanized and biodiversically degraded context of Amman, Jordan’s Capital, Deema Assaf from the ecological research studio TAYYŪN joined the Insight Session as a second speaker, providing the participants with valuable hands-on insights from the MENA region. Mrs. Assaf elaborated on the tedious work with paleobotanists to collect evidence of indigenous species from the region, proven evolutionary resilient towards the local climate conditions. The seeds of these plants known to the soil form the base for a multi-layered ecosystem featuring canopy, sub-canopy, shrubs and ground cover tiers. Over the course of its growth, the micro forest attracts insects, mushrooms and birds. Also edible plants may be included, turning micro forests into sites of (urban) gardening.

In result, the Insight Session provided the participants with new inspiration for their own project development within the scope of the currently running Connective Cities learning processes on ‘Nature at the Heart of Municipal Resilience’ and ‘Green Corridors in the City and its Surroundings’. The potential of the Miyawaki Method to produce fast and self-reinforcing benefits through various ecosystem services and according to the local circumstances makes urban micro forests a tangible and fitting intervention in the current situation of intensifying climate crisis. However, forestry-related preparation – i.e. soil data and seedlings –, as well as institutional backing, secured funding and maintenance of the planting project are key elements for micro forests to thrive.

Connective Cities provides the network for future engagement on the topic and looks forward to share expertise among urban practitioners

Water Resilience – Preparing Municipalities for Drought and Heavy Rainfall

Water is becoming a key challenge for an growing number  of local authorities worldwide. On the one hand, they are increasingly exposed to heatwaves and drought. But on the other hand, heavy rain and high water levels are leading to more frequent flooding. These risks come together to not only impact public health, but jeopradize private property and public infrastructure. Global water demand could significantly exceed available supplies by 2030. Water is thus becoming a strategic resource. It is therefore critical for municipalities to strengthen their water resilience.

Examining their own challenges regarding water resilience, learning from experiences on other continents and developing the courage to implement innovative ideas – all these were the ingredients of the first in-person meeting as part of the Connective Cities Deep Dive, held from 5 to 7 May 2026 in Wuppertal. The group had already met for a virtual kick-off in March 2026. In early 2026, a total of 16 experts from the German municipalities of Dresden, Wunstorf and Wuppertal, as well as from Akkaraipattu (Sri Lanka), Homa Bay (Kenya), Hyderabad (India), Natitingou (Benin) and Niš (Serbia) have started a two-year long working together to explore and analyse innovative approaches such as sponge city concepts, blue corridors and integrated blue-green-red infrastructure, and the possibilities for their implementation. On this basis, they develop and implement locally adapted solutions to address their specific challenges.

The report describes practical examples from Wuppertal and Leipzig, outlines the planned pilot projects of the six municipalities and summarises the key takeaways from the process so far.

Connective Cities at the World Urban Forum 13 in Baku

At the 13th World Urban Forum in Baku, the German Association of Cities and Connective Cities hosted an interactive Academy Session on “AI-supported Visualisation for Affordable Housing and Informal Settlement Upgrading”. The session explored how AI-supported visual tools can help municipalities discuss challenges related to affordable housing, neighbourhood development and informal settlement upgrading in a more concrete and accessible way.

The session built on the work of the Connective Cities Working Group on Sustainable and Affordable Housing. It was deliberately designed not as a technology demonstration, but as a practice-oriented municipal learning format based on real municipal cases. The aim was to explore how visualisation can make complex planning questions more understandable and open new spaces for dialogue between municipalities, technical departments, decision-makers and local stakeholders.

The process started from real images provided from municipal contexts. With the support of CoPlan AI, these images were translated into possible development scenarios. The AI-generated visuals were not intended as final plans. Instead, they served as discussion inputs. They allowed participants to discuss housing quality, density, public space, greenery, climate adaptation, mobility, social infrastructure and possible implementation steps in a more tangible way.

A central added value of the format was the joint work around the images. The visualisations made abstract planning questions visible and enabled a creative, yet critical discussion: What future images are being created? Which assumptions lie behind them? Which opportunities and risks become visible? Which social, spatial, environmental, institutional and financial conditions would need to be assessed before an image can become a realistic planning step?

The session was moderated by Prof. Hilmar von Lojewski, German Association of Cities. Jelena Karamatijevic, Connective Cities / GIZ, provided the conceptual framing and introduced the Connective Cities perspective on municipal practice and peer learning. CoPlan AI, represented by Damiano Cerrone and Sampo Ruoppila, supported the participatory AI-based visualisation process.

Municipal case contributions and reflections came from Nairobi, Huye, Mariental, Hebron, Berlin and the Urban Development Fund in Egypt. Contributors included Godfrey Ngugi, Richard Ndicunguye, Sunday Haimbodi, Husam Shweiki, Lars Loebner and Dr. Marwa Ahmed. They reflected on the visual scenarios from the perspective of local planning realities, implementation constraints and possible next steps.

From Berlin, Lars Loebner from the Senate Department for Urban Development, Building and Housing contributed an important perspective on the role of images in public debates on housing and neighbourhood development. Visual representations can strongly influence how new housing is perceived. Used responsibly, they can help communicate not only abstract plans, but also positive and realistic images of liveable, socially mixed and green neighbourhoods.

A methodological input was provided by Ruvi Y. Suárez Subirana, GIZ / ProUrbano, Santa Cruz, Bolivia. Under the title “From AI Visualisation to Scenario Assessment”, she showed how AI-supported visualisation can be linked to scenario thinking and impact reflection. Her contribution complemented the discussion by underlining that AI images are not plans. Their value emerges when they are used to reflect jointly on impacts, trade-offs and possible implementation pathways.

The discussion showed that AI-supported visualisation can be a useful tool for making planning options more accessible and supporting joint learning. At the same time, participants underlined that visualisations must be used responsibly. They can create expectations and therefore cannot replace planning, participation, feasibility assessments, cost estimation or political decision-making.

From a Connective Cities perspective, the Academy Session provides an important starting point for a deeper exchange on affordable housing, informal settlement upgrading and implementation-oriented municipal project ideas. The added value lies not in the technology itself, but in its potential to strengthen municipal learning processes and help translate visualisation and mapping into realistic, inclusive and financeable urban development pathways.

The “Walkable Triangle” in Kisumu, Kenya

Kisumu, a port city on the shores of Lake Victoria and one of Kenya’s largest cities, is becoming increasingly important for the movement of goods and trade between Kenya and its neighbouring countries, Tanzania and Uganda. With an annual population growth rate of just under 4 per cent, the population has more than doubled in 15 years, rising from around 205,000 in 2001 to at least 422,000 in 2025. This has led to a series of major infrastructure projects, which, however, have primarily focused on motorised transport, even though 53 per cent of residents’ daily journeys are made on foot.

One project under the ‘Kisumu Sustainable Mobility Plan’ is the ‘Walkable Triangle’: the pedestrian-friendly redesign of the three main streets—Oginga Odinga, Ang’awa Ave and Jomo Kenyatta Ave—in a commercial district in the city centre. These streets form a triangle around a sports and park area and are used by over 2,200 pedestrians every day. The aim is to promote non-motorised transport along the 1.5-kilometre stretch, making it safer, more pleasant and accessible, whilst preserving and integrating the existing tree population.

In addition, the city is promoting e-mobility in public transport through a battery-swapping system for motorcycle taxis, known as ‘boda-bodas’, and three-wheeled taxis, known as ‘tuk-tuks’.

The documentation describes the approach as well as the outcomes achieved by this good practice.

Greater Climate Protection and Quality of Life: Green Corridors in the MENA Region

On April 7, 2026, the new Connective Cities learning process on “Green Corridors in the city and its surroundings” was officially launched. The event was organised by Connective Cities in cooperation with the GIZ project Capacity Building through Urban Infrastructure Development (CBUID II) and was offered simultaneously in Arabic, French and English

The workshop was attended by around 70 representatives from eight countries: Algeria, Egypt, Germany, Jordan, Lebanon, Morocco, Palestine and Tunisia. Municipalities and partner institutions from the MENA region as well as the German city of Erlangen were represented. In addition to the official participants of the learning process, an extended circle of municipal representatives was further involved in the virtual exchange.

The kick-off served as technical and methodological introduction to the learning process. The aim was to set initial thematic priorities, to make municipal challenges visible and to create a common basis for further cooperation. At the same time, the event served to prepare the next steps in the process, in particular the in-depth phase and the planned face-to-face conference in Egypt.

AI-supported Visualization as Innovative Tool for Urban Planning

A central element of the kick-off was the joint AI visualization exercise on green corridors and green neighborhoods, implemented via the CoPlan AI platform. Based on images from urban contexts in the participating cities, spatial development future scenarios for climate-resilient, greener and more usable urban spaces were developed.

Around 550 images were produced as part of the exercise. The visualisation served not only to illustrate spatial changes, but also as a methodological tool to stimulate discussion about the feasibility of green corridors. In this sense, the exercise proved to be a suitable introduction for bringing together perspectives from administration, planning and local government practice.

Key Workshop Findings

The kick-off showed that green corridors and green neighborhoods in the participating cities are envisioned predominantly in urban districts and less in the cities’ surroundings. The focus is accordingly not on planning in undeveloped areas, but on the gradual further development of existing urban spaces in which housing, mobility, public use and social functions are already closely intertwined.

In that sense, it also became clear that green corridors have to fulfil several functions at the same time. They contribute to climate adaptation, for example through shading, cooling, better air circulation and water absorption. But they also contribute to the upgrading of public spaces by improving the quality of life and encounters within the city. Especially in dense neighborhoods, green corridors must therefore always be considered as social spaces of mobility and connection.

Another central aspect was the importance of participation and local acceptance. Since identified spaces are usually already intensively used, the involvement of the population is an essential prerequisite for successful implementation. This applies to the usability for distinct groups such as children, families and residents as well as the question of how green measures can be integrated into the everyday urban life.

Contribution from the Urban Development Fund (UDF)

The Urban Development Fund (UDF) underlined the importance of institutional approaches for integrated and climate-resilient urban development in Egypt. The examples presented showed how strategic urban development, upgrading of existing districts, heat reduction and public space can be more closely linked. The UDF thus not only contributed concrete experience from Egyptian practice, but also an important perspective on scaling, institutional anchoring and long-term implementation capability.

Contribution of the City of Erlangen

The city of Erlangen’s contribution illustrated that green corridors must be implemented in conjunction with traffic, accessibility and conflicts over the use of urban space. In their presentation of the local project ‘From two quarters to one campus’, Erlangen representatives demonstrated how a green boulevard, tram, bicycle, pedestrian and motorised traffic, and an existing pedestrian bridge could be brought together within one coherent planning task. Thus, the contribution from Erlangen provided important impetus for an integrated planning approach to green corridors.

Example Cities and Good Practices

During the kick-off, several municipal and institutional examples were presented that are of particular relevance for the further learning process:

  • Erlangen (Germany): integrated planning approach to green corridors in existing urban space, with a focus on Green Boulevard, multimodal mobility, land use and conflicts of use.
  • Aswan (Egypt): Development of the Heat Action Plan for El-Sail Elgadid, including cooling stations, shaded recreation areas and specific offers for children and women.
  • Port Said (Egypt): Approaches to climate-adapted urban development and the upgrading of urban spaces under the specific climatic conditions of a Mediterranean city.
  • Telal Al-Fustat Park, Cairo (Egypt): large-scale greening approach in historic Cairo with positive effects on cooling, air quality and biodiversity.
  • Reviving Historical Cairo (Egypt): Upgrading historic urban areas as a combination of urban renewal, public space and historical identity.
  • Al-Asmarat (Egypt): Participatory upgrading of public spaces in the residential environment as an example of the linking of green and social functions in existing neighbourhoods.

Outlook

Some of the participants at the launch event

The digital kick-off has created a reliable technical basis for the next steps of the MENA learning process. It became clear that the added value of the format lies particularly in synergy effects between concrete municipal examples, institutional perspectives, inter-municipal exchange and visual methods. In the coming phases, the identified topics will be further deepened, approaches between the cities will be further developed and jointly concretized during both online and face-to-face exchanges.
