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.

NEWSLETTER – ISSUE NO. 96, July 2026
Dear Readers,
‘A ship in harbour is safe, but that’s not what ships are built for,” wrote the American author, John A. Shedd. In keeping with this motto, this issue shows how plans are turned into concrete actions, taking into account all risks and side effects. As always, we rely on dialogue among experts.
We provide insight into the development of a 36-month roadmap for the implementation of green hydrogen and sustainable economic development in South Africa, which was created during a five-day expert mission and through inter-municipal cooperation. At the UCLG World Congress, our Lab addressed the question of how municipalities can transform local plans into public services, with a deliberate focus on the challenges involved. A three-day open exchange among 11 municipalities from seven countries on startup support, innovation and career prospects for young people in Bremen has now formed the basis for further collaboration as part of a new learning process. This process is aimed at developing concrete, future-oriented measures and preparing them for implementation.
Best practices can be a source of inspiration. For instance, the municipality of Bağcılar, a district of Istanbul, has developed a digital twin for disaster management in this earthquake-prone region. This digital twin is now also being used for infrastructure planning, particularly with regard to climate resilience, and provides digital citizen services.
Municipal partnerships for civil protection, critical infrastructure, and crisis preparedness are also recognized by the 2027 Goerdeler Prize. In addition to the prize money, the award offers high-profile recognition.
We hope you find this an inspiring read.

Driver of Green Transformation: Connective Cities Expert Mission in Waterberg
Communal Dialogue on Green Hydrogen and Sustainable Economic Development
From 8 to 12 June 2026, Connective Cities organised an international expert mission in partnership with the South African Local Government Association (SALGA) and the Waterberg District Council. The mission aimed to support economic transformation and green industrial development at a local government level. The mission brought together municipal representatives, researchers, and experts from industry and practice from South Africa and Germany to share knowledge and identify the economic potential of green hydrogen. The mission concluded with a strategy workshop, during which participants created a 36-month regional development roadmap.
From Challenge to Practice: How Municipalities Turn Local Plans into Public Services
Connective Cities Lab at the UCLG World Congress 2026
The lab focused on a challenge shared by local authorities worldwide: strategies and development plans are in place – yet translating them into effective, inclusive and sustainable public services is often a complex task. The session therefore deliberately centred on concrete experiences of implementation, challenges and collaborative learning. Among other things, the discussion covered examples from waste management in the city of Krefeld, the Kiunga Solar-Powered Desalination Initiative in Lamu County, Kenya, and the implementation of infrastructure projects in the municipality of Pékine in Senegal. The lab highlighted how international municipal exchange can go beyond traditional ‘good practice’ presentations, with local authorities speaking openly about challenges and working together to find solutions.
Start-ups and Innovation: Labour Market Opportunities and Prospects for Young People
International Municipalities Exchange Ideas in Bremen, Germany
From 30 June to 2 July 2026, around 35 experts from 11 local authorities and seven countries gathered in Bremen to exchange experiences, learn from one another, and develop new approaches together. The event focused on the opportunities that start-ups and entrepreneurship create for employment, economic development, and social participation among young people. A key finding was that, despite differing local conditions, municipalities around the world face many similar challenges. Young entrepreneurs need access to advisory services, networks, financing, suitable infrastructure, and practical education. Municipalities play a crucial role as facilitators, supporters, and enablers of thriving local entrepreneurial ecosystems. The event marked the launch of a new Connective Cities learning process.
How a municipality in Istanbul combines citizen services with data-driven urban risk management
Bağcılar is one of Istanbul’s most densely populated districts, with approximately 710,000 inhabitants. Located on the coast of the Sea of Marmara, it covers an area of about 22 square kilometers. As a municipality in a region with a high risk of earthquakes, Bağcılar faces the urgent task of taking precautions to protect its population and urban systems in the event of a crisis. With their ‘Digital Urban Twin Platform’, the administration aims to enable faster assessment of situations in emergencies and disasters. Digital simulation of risk scenarios – such as tsunamis following earthquakes – allows for improved civil protection measures and necessary adjustments to urban systems. Furthermore, continuous digital monitoring of building conditions enables the identification of heat islands, for example, and supports the efficient planning of photovoltaic systems.
Public service delivery, local gender equality policy and the start of a new governance cycle
From 22 to 25 June 2026, the World Congress of the World Organisation of Local Authorities (United Cities and Local Governments, or UCLG) took place in Tangier, Morocco. With the theme of ‘A New Generation of Universal Local Public Services’, the event attracted over 3,000 delegates from around the world. Alongside the technical discussions in numerous barcamps and side events, and the many networking opportunities, the Congress marked the beginning of a new governance cycle for the international local government movement. Another significant event was the inaugural UCLG Women’s Assembly, which convened female mayors, governors, and other female local decision-makers from across the globe. The focus was on exchanging views on local gender equality policies, empowering women in political leadership roles and developing the Feminist Municipal Movement within the UCLG further.

The mission formed part of broader efforts for the Just Energy Transition and complemented the work of South Africa’s Just Energy Transition Municipal Council (JETMC), which is strengthening municipal readiness for a shift toward cleaner and more sustainable energy systems. Through policy discussions, technical presentations, and site visits to strategic infrastructure such as the Eskom Matimba Power Station and Exxaro Solar Power Station, participants gained valuable insights into the challenges and opportunities facing regions transitioning from coal-dependent industries.
Central themes of the mission were the role of green hydrogen in driving local economic development, industrial diversification, and job creation. Waterberg District Municipality highlighted the importance of ensuring that the transition is both environmentally sustainable and socially inclusive. Participants learned about progress made in Waterberg District municipality in cooperation with both Lephalale and Mogalakwena Local Municipalities, including municipal skills development initiatives, governance structures, funding mobilization efforts, and partnerships supporting green hydrogen capacity building.
The Waterberg Development Initiative (WDI) presented its vision for a coordinated regional development model that aligns municipalities, industry, and communities around shared economic and sustainability goals. Discussions also featured contributions from national government representatives, development partners, and municipalities already advancing hydrogen-related projects, demonstrating growing momentum behind South Africa’s hydrogen economy.

Combination of future-proof mobility forms
Kick-Off of the New Learning Process on Sustainable Mobility in Bonn
From 25 to 27 November, Connective Cities hosted a dialogue event in Bonn. 38 experts from 20 municipalities in 11 countries followed the invitation to share their innovative project approaches with colleagues and collaborate on new implementation ideas. Small municipalities such as Schlangen in the Teutoburg Forest, with a population of around 9,000, were represented, as well as metropolises with millions of inhabitants, such as Rio de Janeiro and Munich. The innovative approaches were equally diverse.
Unlocking the potential of new technologies at the local level
Green hydrogen is rapidly gaining global prominence as a crucial energy carrier for the future. For many African countries, abundant solar and wind resources give cities a unique advantage, positioning them not only as innovation hubs but also as centers for technology transfer, workforce training, and industrial diversification. By integrating sustainable use of green hydrogen into urban planning, municipalities can enhance energy security, attract long-term investment, and build more resilient, climate-friendly local economies—ultimately becoming key drivers in the global clean-energy transition.

Green hydrogen is rapidly gaining global prominence as a crucial energy carrier for the future. Although much of today’s discussion focuses on hydrogen production and its export potential, domestic consumption of green hydrogen offers equally significant opportunities for local economic development—strengthening municipal infrastructure, creating skilled jobs, and stimulating new economic activities along various value chains. For many African countries, abundant solar and wind resources give cities a unique advantage, positioning them not only as innovation hubs but also as centers for technology transfer, workforce training, and industrial diversification. By integrating sustainable use of green hydrogen into urban planning, municipalities can enhance energy security, attract long-term investment, and build more resilient, climate-friendly local economies—ultimately becoming key drivers in the global clean-energy transition.
To advance the exchange of best practices and accelerate strategy development between African and German cities, Connective Cities hosted its second workshop on “Exploring the Potential of the Green Transition for Local Economic Development” held on 25–27 November 2025 in Mombasa. Representatives from Mauritania, Kenya, South Africa, and Germany participated. This edition focused on improving technological readiness for green hydrogen production, addressing local implementation challenges andstrengthening regional competitiveness among other readiness issues. The discussions further emphasized the importance of involving , and integrating universities, research institutions and start-ups as key drivers of job creation and innovation.
The City of Nakuru, Kenya presented its benchmark strategy to position itself as a model green city and a leading hub for green fertiliser production within is floriculture sector, reducing import dependency and supporting the emergence of new green industries. With its proximity to the rift valley geothermal vents, Nakuru is well positioned for cost- competitive green hydrogen production. The city aims to attract pilot projects, applied research initiatives, and local and international start-ups working along the green hydrogen value chain., reinforcing its long-term vision as a regional clean-energy and innovation hub.

Kenya has adopted a national Green Hydrogen Strategy and participates in regional African hydrogen initiatives. Mombasa, as a major port city, holds strategic significance for export logistics and coastal project siting. While early national activities have focused on potential assessments and pilot sites, coastal locations like Mombasa are increasingly viewed as gateways for logistics, export-oriented hydrogen production, and coastal renewable-energy projects. The city now seeks to leverage its strategic location to establish itself as a global player in hydrogen-powered logistics and to develop the port into a logistics cluster that attracts innovative local and international investment supported by a skilled workforce.
In South Africa, the Waterberg region in Limpopo forms part of the national “Hydrogen Valley,” stretching across Limpopo, Gauteng, and KwaZulu-Natal. Mining and industrial operations in the Waterberg–Mokopane corridor are being integrated into hydrogen and platinum-group-metal value chains. Recent feasibility studies and national green hydrogen planning have made the region increasingly attractive to investors. The local development vision is to integrate renewable energy generation with mining operations and downstream green hydrogen and green ammonia applications. This approach aims to link industrial decarbonisation and new export opportunities with local job creation and investment. Waterberg is also seeking to strengthen collaboration with universities by fostering local and international research partnerships to spur pilot projects and nurture green start-ups across emerging value chains.
Mauritania has become a high-potential green hydrogen country due to its exceptional wind and solar resources and favourable export position toward Europe. Several large-scale, export-oriented hydrogen and ammonia projects have been announced or are under development. While the national strategy prioritises export-driven green hydrogen production, it also emphasises renewable energy use to support domestic power grids and industry. However, as national projects advance, municipalities within Nouakchott—particularly Sebkha and Ksar, – continue to face high electricity costs, pollution, limited infrastructure, and the absence of clear municipal hydrogen strategies. These communes are not seeking merely to host hydrogen developments, they aim to participate meaningfully in shaping equitable, community-centered value creation within Mauritania’s emerging green hydrogen economy. The City of Nouakchott through its private sector and international partnerships, now seeks to position itself as an active player in his transition with a focus on modernizing urban services , strengthening governance, and building local private-sector capacity ultimately becoming a regional hub for green urban development, logistics, and industrial enterprises linked to the green hydrogen value chain.
The participating German cities also shared key insights and updates on their latest initiatives. Karlsruhe highlighted its hydrogen hub around the Rhine ports (H2iPortKA) and its strong research ecosystem in collaboration with the Karlsruhe Institute of Technology and the Fraunhofer Institutes. Particularly noteworthy is the dynamic start-up and spin-off environment, which demonstrates how the green transition can generate new jobs and investment for an entire region.
Heilbronn, well known as a centre for technology and hydrogen innovation within Germany’s automotive and engineering clusters, aims to use green hydrogen to diversify its industrial base, upgrade workforce skills, and anchor research-driven companies in the region. Heilbronn University and nearby Fraunhofer initiatives are expanding applied research and innovation centers—including those focused on hydrogen technologies—leveraging strong industry links for piloting and skills development.

The workshop underscored the vast opportunities emerging around green hydrogen production across regions endowed with abundant renewable energy resources.. However, cities and regions hosting these new green industries are often overlooked in national strategies that prioritize high-profile investments and export ambitions. Many localities remain uncertain of how they and their populations can directly participate in these developments. Significant technological and institutional gaps persist, and synergies between international high-tech initiatives and local realities are not automatic. As a result, municipalities are increasingly seeking models, international experiences, expertise, and partnerships to strengthen their capacity and create a level playing field:- one that enables prosperous, innovative and equitable local economies in which nations, investors, and communities all benefit alongside advancing technologies
The global transition towards sustainable transportation is essential for a sustainable future. Experts agree: there is no one-size-fits-all solution for sustainable mobility. Instead, we must create public transport services that include a range of mobility solutions and combine them in the best possible way – in a smart, accessible, and time- and resource-efficient manner. In addition, measures must be tailored very individually to the needs of citizens in individual regions, cities, counties, or municipalities. For strategic planning, German municipalities often develop concepts across regions in collaboration with transport and special-purpose associations. Innovative solutions and considerations for connecting transport are particularly reflected in concepts for mobility, tourism, or strategic regional development. In the Global South, municipalities are often challenged by urbanization and increasing traffic volumes to formulate solutions for developing their communities, and are increasingly relying on digital solutions and private providers.
The dialogue event marks the start of a one-year learning process in which participating municipalities are also invited to take part in further optional activities.
Objectives of the event
The event brings together experts from cities, counties, and municipalities and supports international expert exchange on the interaction of sustainable forms of mobility.
Goals for participants
Learn about innovative mobility solutions and how to combine them in a smart way
Compare strategic approaches and instruments for sustainable mobility in cities and surrounding areas
Acquire skills to solve challenges in the implementation of planned measures, drawing on an extended network and the method of peer consultation
In addition: getting to know each other as a basis for expanded peer exchange, e.g., through professional exchange trips

African and German Cities Power a Shared Vision for a Just, Climate-Smart Hydrogen Future
Cities across Africa and Europe are accelerating their role as frontline actors in the global green transition, driving innovation, investment, and climate resilience from the ground up. Following the successful launch of the Hydrogen Cities Working Group earlier this year in Naivasha, Kenya, Connective Cities will convene the second peer-learning workshop on 24–27 November 2025 in Mombasa, Kenya.
This flagship event will bring together city leaders, practitioners, industry innovators, researchers, and development partners to scale up municipal hydrogen strategies and unlock new pathways for green industrialization, inclusive growth, and just transition at the local level.
From Naivasha to Mombasa: Turning Ideas into Impact
The inaugural workshop in Naivasha brought together over 30 municipal representatives and technical experts to explore how cities can anchor the emerging green hydrogen economy in local value creation and job generation. It underscored hydrogen’s role not only as a clean-energy vector but as a catalyst for climate-neutral industrial ecosystems, skills development, and innovation-driven urban transformation.
Case studies showcased how municipalities are positioning themselves along the hydrogen value chain — from production and storage to end-use applications in mobility, manufacturing, and port logistics. Examples ranged from Namibia’s evolving hydrogen hubs to Germany’s Heilbronn and Karlsruhe regions, where local governments are building innovation clusters, R&D partnerships, and market linkages for hydrogen deployment.

Participants also highlighted the importance of integrated urban governance — combining spatial planning, transparent land management, and strong stakeholder engagement — to ensure hydrogen projects deliver tangible community benefits.
Key takeaways from Naivasha included:
Municipal leadership as a driving force for innovation, investment, and policy alignment.
Local value creation through SME participation, skills training, and green entrepreneurship.
Institutional capacity and human capital as preconditions for hydrogen readiness.
Peer-to-peer collaboration as a catalyst for scaling solutions and knowledge transfer.
Since Naivasha, cities have been actively refining their project concepts, forging cross-regional partnerships, and identifying bankable entry points to accelerate their green transition agendas.
Green Hydrogen: Powering Sustainable, Inclusive Urban Futures
Africa’s vast solar and wind potential places its cities at the heart of the global clean-energy transformation. Green hydrogen — and its derivatives such as green ammonia and e-methanol — offers a once-in-a-generation opportunity for low-carbon industrialisation, climate resilience, and circular economy development.
For municipalities, this transition means:
Developing innovation clusters and hydrogen corridors that attract private investment.
Expanding renewable energy infrastructure and smart urban grids.
Enhancing water security and resource-efficient technologies such as desalination and wastewater reuse.
Creating green jobs across engineering, construction, logistics, and research sectors.
Catalysing start-ups, incubators, and technology partnerships.
Building skills pipelines aligned with future hydrogen markets.
Yet, challenges persist — from infrastructure gaps and regulatory complexity to financing bottlenecks and local ownership. The Hydrogen Cities Working Group provides a collaborative platform where cities can co-create solutions, de-risk investment, and ensure the green transition remains inclusive, equitable, and locally anchored.
What to Expect in Mombasa: Scaling Up and Going Deeper
The upcoming workshop in Mombasa will mark a critical shift from strategic visioning to operationalisation and project implementation. Over three days, participants will:
Present project updates and refine concepts through structured peer-review and coaching.
Engage in interactive sessions on land use, water-energy nexus, and industrial cluster design.
Explore innovative financing instruments, including blended finance and PPP models.
Participate in hands-on peer-coaching clinics to advance project maturity.
Exchange with international experts on policy frameworks, investment pipelines, and market integration.
Join a site visit to the Mombasa Port and Special Economic Zone to identify real-world opportunities for green hydrogen applications.
The event will feature keynotes from government and private-sector leaders, expert panels, and networking sessions to strengthen partnerships between African and German municipalities.
Confirmed participants include cities such as Mombasa, Naivasha, Lüderitz, Arandis, Nouakchott, Waterberg District, Hamburg, Karlsruhe, Heilbronn, and Freudenstadt — forming a growing alliance of municipalities championing decentralized, climate-smart hydrogen ecosystems.
Looking Ahead: Cities as Catalysts of a Just Green Economy
As the global energy landscape transforms, cities that act decisively today will become the engines of tomorrow’s green prosperity. The Mombasa workshop represents another milestone in empowering municipalities to lead the hydrogen-powered urban transformation — advancing climate action, economic resilience, and social inclusion in equal measure.
Through the Hydrogen Cities Working Group, Connective Cities continues to bridge continents, connect expertise, and translate ambition into action — ensuring that the hydrogen revolution drives sustainable, locally embedded, and future-ready urban economies.
From Naivasha to Mombasa, cities are demonstrating that the green transition starts locally — and scales globally.
