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.

Climate Proofing the Built Environment: Technical Support for Climate Resilient Infrastructure

The second Africa Urban Forum (AUF), organized under the African Union framework with the support from UN-Habitat and UNECA, took place from 8 to10 April 2026 at the Kenyatta International Conference Centre in Nairobi, Kenya. AUF welcomed a diversity of participants, among them politicians, private sector, civil society, development partners and interested members of the public as well, to discuss the conferences’ topic: ‘Adequate Housing for All: Advancing Socio-economic and Environmental Transformation towards the Realization of Agenda 2063’.

At AUF, Connective cities alongside GIZ partner projects Covenant of Mayors Sub Sahara Africa (CoMSSA) and Resilience Initiatve Africa (RIA) organized and facilitated a side event on 9 April, titled Climate proofing the built environment: Integrated Technical Support for Climate-Resilient Infrastructure.

The events’ panel-discussion included international experts, development finance institutions, and local administrations. Thereby, participants could gain insights from local government representatives from Embu, Kenya, and eThekwini, South Africa on how to combine collaborative governance with technical expertise for climate resilient infrastructure. In this regard, the launch of the Embu Final Prefeasibility Technical Assistance Report on Solid Waste Management Infrastructure illustrated the need for comprehensive data gathering prior to project implementation.

Next to the case studies, panelists discussed institutional arrangements and policy approaches related to financing sustainable urban infrastructure. For example, a representative of the European Bank for Reconstruction and Development emphasized that cities must leverage on digitalization of revenue collection to meet ever-rising financial demands and also demonstrate to potential financiers built-in capacity to collect, allocate, and use financial means effectively.

Furthermore, a program manager from the European Investment Bank noted that for development projects to be implemented efficiently, the national and sub-national levels of government must enter into collaborative modes of governance, whereby they complement each other in sourcing funds from potential financiers. The program manager further advocated for a non-fragmented approach towards infrastructure development to avoid wastage and duplication of effort and resources.

In sum, the AUF side-event, by bringing together financial institutions and local government leaders, provided valuable insights into how to comprehensively think sustainable urban development as a basis to successfully build climate-resilient infrastructure in African cities and beyond.

Green Corridors in the city and its surroundings

Kick-off Event: 7th – 9th April 2026 (TBC) in Egypt

Local authorities in Germany, North Africa, and the Middle East face similar challenges in the face of climate change. They are called upon to translate general strategies for climate change adaptation and climate protection into concrete local measures. One option is to develop green corridors – e.g., as green walkways in city centers or as green corridors in the surrounding areas and new neighborhoods. These enable improved fresh air supply, quality of life, and more efficient water management. Green corridors can also be used for local recreation and heat protection in municipalities.

Against this backdrop, Connective Cities offers experts from local governments in Gemany, North Africa and Middle East the opportunity to develop concrete solutions for their own contexts and exchange ideas with each other as part of a one-year learning process.

Main areas of Work

The structured learning process will focus on:

  1. Green corridors as fresh air corridors between cities and their surrounding areas
  2. Green paths in cities and old city centers
  3. Green new and existing neighborhoods

 

The methodology

The learning process follows a modular approach with the following objectives:

  1. Supporting participating municipalities in developing solutions through peer learning and tailored technical advice to promote green corridor solutions.
  2. Developing the participants’ skills so that they are better able to implement organizational changes and improve procedures and methods in their own municipalities.
  3. Supporting participating municipalities in their methodological approach and the development of financially viable solutions.

 

As part of the learning process, best practices for green corridors and climate-friendly urban planning will be presented. Participating municipalities will engage in peer learning with others to develop concrete solutions for their individual contexts. These solutions can bring about organizational changes to improve procedures, methods, and data availability, as well as the concrete implementation of pilot measures.

Using a co-creative approach, participants will be involved in a structured creative problem-solving process. This includes

  1. observing and understanding current municipal practices to identify challenges and gaps,
  2. brainstorming and developing concrete solutions, and
  3. testing the solutions with a group of stakeholders, including citizens and experts, to obtain feedback.

 

Duration

The learning process will span a period of one year, beginning with a kick-off workshop in Egypt in April 2026. A total of two German and approximately 10 municipalities from the MENA region will participate in the learning process.

Participation and contact

We are looking for experts from local governments in Gemany, North Africa and Middle East (district offices, city administrations, municipal companies, etc.) who can contribute a project or idea for a solution for green corridors to the learning process. Ideally, two experts from one municipality will apply and be able to anchor the change process in the administration in the long term. The participation costs (accommodation and board) are covered. The conference language is English and French.

If you are interested in the learning process, please apply by February 20, 2026, via this link: Learning process MENA Green Corridors 2026/2027 | Connective Cities Network stating your municipality, position, and the project/challenge in the area of green corridors.
