Online Kick-Off for Municipal Water Resilience

24 March 2026 was the big day! The in-depth learning process “Water Resilience: Strengthening Municipalities against Drought and Heavy Rainfall Events” kicked off shortly after the World Water Day. Droughts, heatwaves, heavy rainfall and flooding are on the rise, putting a strain on infrastructure, public health and municipal budgets. At the same time, urbanisation is intensifying competition for water.

Many major cities are already experiencing severe water stress, and the global demand for water could significantly exceed the available supply by 2030.
Water scarcity has long been an obstacle to development for countries in the Global South, but in the future, all regions worldwide will have to adapt to fluctuating water availability and growing conflicts over its use. Water is set to become the defining strategic resource of the 21st century.

Key solutions are emerging at a local level. Although the broader circumstances vary greatly, local authorities face similar structural challenges, making exchange and collaborative learning particularly valuable.

As part of our ‘Deep Dive’ on the topic of ‘Water-Resilient Municipalities’, we are bringing together experts from eight municipalities in Benin, Germany, Kenya, India, Serbia and Sri Lanka. Over a two-year period, they will discuss innovative approaches, such as sponge city concepts, blue corridors and integrated blue-green-red infrastructure, and develop and implement locally tailored solutions to their respective challenges.

During the initial virtual meeting, the municipalities presented their local challenges, identified initial similarities, and prepared for the first in-person working meeting in Wuppertal in early May. Further updates from our ‘Deep Dive’ project will follow from May 2026.

The participating cities are: Natitingou (Benin), Dresden, Wunstorf and Wuppertal (Germany), Homa Bay (Kenya), Hyderabad (India), Niš (Serbia) and Akkaraipattu (Sri Lanka).

Shaping Mobility on a Sound Basis: Decisions Based on Reliable Information

What does it take to make mobility in our municipalities more sustainable? New technologies? More funding? The will of the citizens? One answer: We need reliable information to make informed decisions that can bring about targeted changes. At the dialogue event “Sustainable mobility—Combination of future-proof mobility forms” last November, 38 participants from 11 different countries identified data management and use as a central aspect of the transportation transition. On 23 March 2026, around 20 participants in the Connective Cities learning process came together again for an online follow-up session to engage in an in-depth discussion on the topic of ‘mobility data management’. During the two-and-a-half-hour exchange, a total of 5 municipalities presented aspects of their mobility data management as a basis for transportation planning decisions.

 

“Data (or the absence) can be a reason to unnecessarily delay important decisions. Also make sure you apply the correct data for the correct application.”

Those with the capacity and financial resources can undertake the process of developing a Sustainable Urban Mobility Plan (SUMP). This multi-year, partly participatory data collection and analysis process includes a catalog of Sustainable Urban Mobility Indicators (SUMI) and concrete recommendations for action. Dr. Metin Mutlu Aydin, Associate Professor at Ondokuz Mayıs University, who provided academic guidance during the three-year development of the SUMP in Trabzon, Turkey’s easternmost major port city on the Black Sea, presented the process and the recently published results to the participants in his keynote speech:

SUMPs are strategic plans used to formulate concrete, participatory responses to the mobility needs of people and businesses. To this end, the team of experts responsible draws on primary and secondary data and bases its recommendations for action on a large-scale participatory process. The city of Trabzon utilized existing statistics but also invested in a variety of digital measurement methods that enable automated, real-time data collection and ensure the monitoring of set goals. The most comprehensive data was collected through participatory means, including institutional meetings, exchanges with professional and civil society organizations, and public engagement via online surveys and social media. In Trabzon’s case, a total of 95 institutions were consulted. Integrated scenario analyses highlight the need for action: in this coastal city with hilly topography, for example, day trips by car already result in high traffic volumes today. By 2040, this number is expected to nearly double. Therefore, the city must provide alternatives, particularly along the identified main corridors.

In Munich, data is continuously collected and analyzed using a multimodal traffic model (“M3”); the City of Munich places a high priority on its data strategy. Attila Lüttmerding, Head of the Fundamentals and Data Division in the City of Munich’s Mobility Department, emphasizes that data should not be collected for its own sake, but rather that efforts must be goal-oriented. In addition to climate neutrality and traffic safety, Munich aims to significantly improve the use of public transport, walking, cycling, and electric vehicles. The data clearly demonstrates this success: The “traffic jam capital” has been showing a clear trend toward becoming a “pedestrian-friendly city” for several years now; the use of sustainable modes of transportation is increasing despite rising car ownership. Especially in the city center, these options are now an alternative for many. To determine this, the city uses a variety of technologies and—pragmatically—continues to use manual counting methods. The robust data set enables Munich to provide accurate information, including regarding the EU’s mobility indicators, which are intended to ensure greater international comparability in the coming years.

Viktor Goebel, project manager in the City of Munich’s Mobility Department, highlighted how sharing services can become more user-friendly if they are tailored to user behavior and closely monitored. Operators must adhere to the rules imposed on them by the city: E-scooters may not be parked in certain areas, and there are also limits on, for example, the number of scooters per zone, so that pedestrian and bicycle traffic is not disrupted by the additional mobility option. Data analysis is used here to determine the needs of individual areas and identify which sustainable forms of mobility can be effectively implemented. The significant level of interest shown by Munich’s residents thus justifies municipal subsidies.

Bremen, Windhoek (Namibia), and La Paz (Bolivia) provided brief insights into how data is managed in other municipalities. While data in Bolivia is managed as open data and public portals facilitate its use, the digital ticketing system in Windhoek serves as a new source of important data, enabling, among other things, the identification of areas where fare evasion poses a financial risk to operators.

In subsequent breakout sessions, participants engaged in in-depth discussions and gained further insights:

“Companies are always asking for money, so you need to do your own research to be able to evaluate their offers”

However, the group discussions also highlighted how varied the availability and resources for data analysis are, and that it is important to consider many suggestions within their respective individual contexts.

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.

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

Author: Burkhard Vielhaber

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

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
