Green Corridors in the city and its surroundings

Posted on by burkhard

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.

The Hamburg Hydrogen Strategy

Posted on by burkhard

On 18 March 2026 from 10:00 to 11:30 CET, the Hydrogen Economy Unit of the Ministry of Economic Affairs and Innovation of the Free and Hanseatic City of Hamburg, Germany, will present the Hamburg Hydrogen Strategy in an Insight Session. The focus will be on how the Hamburg metropolitan region is positioning itself as a leading international hub for the hydrogen economy.

As a major port and logistics center, Hamburg plays a strategic role in linking global hydrogen supply chains with national demand. The strategy follows an integrated approach to scaling production, imports, infrastructure, and industrial applications, thereby making a key contribution to climate neutrality.

Through targeted investments, policy coordination, and international partnerships, Hamburg is strengthening its hydrogen ecosystem — from large-scale import corridors and hydrogen-ready infrastructure to innovation clusters. The overarching goal is to establish Hamburg as a gateway for hydrogen into Germany and Europe, as well as a center for industrial transformation and sustainable growth.

Join us to discuss how international cooperation, economic competitiveness, and sustainable transformation can work together to advance the hydrogen economy.

Free E-Car Sharing for the Trip to the Train Station

Posted on by burkhard

Publisher: Connective Cities

The approximately 9,300 inhabitants of Borgholzhausen in Germany are spread over an area of 56 km². One third of the population lives in the town centre, while the other two thirds live in eleven settlements, each with a few hundred inhabitants. From the station in Borgholzhausen, the NordWest-Bahn railway connects to the neighbouring cities of Osnabrück in the north-west and Bielefeld in the south-east. However, there is no local public transport connecting the settlements to the station.

Against this backdrop, Borgholzhausen has developed a new type of electric car sharing service that enables residents of the municipality to book the last mile from the train station to their home conveniently and at no extra cost, included in the price of their train ticket. The neighbouring municipality of Halle-Künsebeck is participating in this innovative mobility concept.

Anyone with a valid public transport ticket can now book an electric vehicle free of charge for a maximum of half an hour on specified routes between certain stops. It is also now possible to rent a vehicle at a moderate cost through the classic car-sharing scheme. The income from this reduces operating costs.

This good practice describes how this model, which is unique in Germany to date, was developed, how it is being implemented, what advantages it offers and what lessons have been learned so far.

AI-based Visualisation for Sustainable & Affordable Housing

Posted on by burkhard

Cities worldwide face growing challenges in delivering affordable housing, upgrading informal settlements and creating inclusive public and social spaces. Addressing these challenges requires participatory planning, clear communication and tools that make spatial options tangible for citizens and decision-makers.

The Connective Cities Sustainable & Affordable Housing Working Group provides a global peer-to-peer learning platform supporting municipal innovation through the exchange of project ideas, planning approaches and practical solutions. Building on earlier exchanges (2024–2025), the working group has entered a new phase (2026–2028) focusing on visualisation methods to support reverse planning and implementation-oriented project preparation.

On 22 January 2026, Connective Cities convened an online peer-learning workshop on AI-based visualisation for sustainable and affordable housing. Cities from Sub-Saharan Africa. Europe and the MENA-region worked hands-on with the AI-based visualisation platform CoPlan AI, jointly generating and refining visual concepts while explaining their local planning contexts, constraints and priorities. The session followed a peer-learning format and focused on learning and exchange, not on final design solutions.

Participating Cities

Participating cities included Kisumu, Nairobi, Turkana County, Kitengela Municipality, Windhoek, Mariental, Huye, Rwamagana, Lusaka, Mazabuka, Mangaung (Bloemfontein), Mwanza, Hebron and Berlin.

Selected City Examples

Huye (Ruanda)

Model for Huye | Photo: Connective Cities

Huye explored the upgrading of a dense informal settlement along a main street. Visualisations focused on combining higher density with neighbourhood-scale principles, introducing a central public plaza, integrating solar rooftops and green façades, and creating small-scale social infrastructure such as playgrounds, community spaces and local shops.

Berlin (Germany)

Berlin tested a timber-based affordable housing complex in a new development area with tram access. The concept included multi-layered block perimeter development, commercial uses on the ground floor, affordable housing for approximately 1,000 residents in upper floors, and integration of cycling infrastructure, green façades and solar lighting. The city input was jointly contributed by Lars Löbner and Larissa Häeschel from the Berlin Senate Department for Urban Development, Building and Housing.

Nairobi (Kenya)

Visions for Nairobi

Nairobi focused on low-rise housing along a busy urban street. The scenario combined affordable brick housing with space for local public and semi-public transport, including boda boda stations. Rear-staggered buildings, active ground floors, shops and green façades were used to improve public space quality and local accessibility.

Hebron (Palästina)

Hebron explored a park-centred development at the urban fringe, combined with affordable housing. The park served as the main structuring element, complemented by housing forms derived from traditional models, shaded seating areas, climate-adapted vegetation and pathways following the natural terrain.

Methodological Example: Santa Cruz de la Sierra (Bolivia)

Santa Cruz de la Sierra was presented as a methodological example by Ruvi Suárez (GIZ Bolivia). Based on her work with a student group, she introduced backcasting approaches and a model for assessing the impacts of different urban development scenarios. The example illustrated how AI-supported visualisation can be combined with impact-oriented planning to support the transition from vision to implementation, particularly in the context of affordable housing and public and social spaces

Reuse Instead of Demolition: 2nd Hands on Public Buildings

Posted on by burkhard

Author: Dr. Susanne Reiff

Publisher: Connective Cities

For over a year, more than 30 experts from six countries worked as part of Connective Cities‘ learning process ‘2nd Hands on Public Buildings. Repurposing Modernist Public Buildings from the 1960s and 1970s ’ on solutions for aging public buildings from the 1960s and 1970s. How can they be sustainably reused or repurposed instead of being demolished? At four events and two working meetings between September 2024 and September 2025, they learned about current trends in this area, deepened their knowledge, heard details about possible solutions from external experts, and inspired each other with their respective experiences, approaches, and ideas.

But the participants didn‘t just exchange ideas, they also took action. They further developed the project ideas they presented at the dialogue event in Berlin in September 2024 or, in some cases, implemented them directly, taking up suggestions from the other participants. The innovative and very diverse projects impressively demonstrate the potential of the paradigm shift away from rapid demolition toward well-thought-out reuse and conversion.

The documentation provides insights into the key findings.

Sustainable mobility – Combining future-proof mobility forms

Posted on by burkhard

Author: Burkhard Vielhaber

Publisher: Connective Cities

In a world increasingly affected by climate change and resource scarcity, a corresponding transport revolution is becoming increasingly important. The goal is to reduce emissions and energy consumption while improving quality of life for users, by combining various forms of sustainable mobility. These include electric vehicles, car sharing, bicycles, public transport and walking. Digital technologies can play a key role in ensuring this transition to sustainable mobility is user-friendly, socially balanced and economically efficient.

Although this approach may seem plausible and simple, it is difficult to implement in practice. There is no one-size-fits-all solution to sustainable mobility. Measures must be tailored to the specific needs of citizens, as well as to the existing buildings, infrastructure, and topography of a municipality. Rural communities and districts naturally have different requirements to cities with millions of inhabitants. In Germany, in particular, questions arise regarding intercommunal transport connections, as well as strategies for tourism and regional development. Rapid urbanisation poses additional challenges for many cities in the Global South. Furthermore, municipal budgets are often tight and data is insufficient in both the Global North and South.

38 experts from 20 municipalities in 11 countries accepted Connective Cities‘ invitation to Bonn, where they discussed their innovative project approaches with colleagues and collaborated on new implementation ideas. Represented were small municipalities such as Lahntal with around 7,200 inhabitants, rural districts, and metropolises with millions of inhabitants, such as Rio de Janeiro and Munich. The innovative approaches were equally diverse. The international exchange of experiences provides motivation at a time when sustainability issues are under increasing political pressure. The challenges are surprisingly similar, and solutions are often transferable.

The documentation briefly outlines the different approaches and summarises the challenges and possible solutions.
