The project will deliver urban food system transformation via Bauhaus Bites (BB) Food Environments, co-created and demonstrated in 7 cities at different levels of societal readiness, their transferability discussed with sister projects and European/global networks, and the results summarised in a Playbook for broad adoption. Bauhaus Bites Food Environments are urban and peri-urban ecosystems that commit to implementing sustainable healthy diets, amplified by the New European Bauhaus, and fortified with Nature-Based Solutions, ensuring that the transformed food environments of tomorrow are sustainable, inclusive and beautiful. By merging the key perspectives of European and global strategies such as the Farm to Fork and FOOD 2030 strategies, the Planetary Health Diet and the Planetary Health Diets with the New European Bauhaus values and principles, Bauhaus Bites offers a unique approach not yet seen in food system transformation projects, that will reimagine these food environments together with local, culturally diverse communities, customised to meet their needs, and anchored in social meeting spaces that carry meaning for them. The project will co-create BB Food environments in 3 Trailblazers (Birmingham, Fundão, Zagreb) and 4 Twins (Murska Sobota, Ostend, Palermo, Sarajevo) with different geographies, sizes, demographic challenges and societal readiness, boost mutual learning through a Community of Practice, document their added value with science-based indicators to inform high-level policy-making, test them for transferability with European/global networks, and summarise the learnings, guidelines, methods and examples in a Playbook. The BB approach will be based on inclusive participation and co-creation, including city and regional authorities, community- and business-driven initiatives, and inhabitants and end users of the food environments.

C2G supports 8 cities to move away from a project-by-project NBS intervention approach towards the development of greening and renaturing strategies that (a) are cross-scalar and participatory (b) inform existing development agendas and policies, and (c) are implemented through demonstrators that create tangible impact on the ground for the local communities and broader ecosystem. This paradigm shift is founded on the operationalisation of Ecosystem Services (ES) in city decision-making at the district and city scale. Specifically, C2G assesses the current supply of ES in cities (e.g. flood and heat risk reduction, recreation) and runs targeted engagement activities to map community vulnerabilities, as perceived by stakeholders themselves. These vulnerabilities translate into key place-based priorities, i.e. the demand for ES. C2G works intensely to bridges this gap between supply and demand using districts as entry points. Considering that citizens experience life and meet their needs in this spatial scale, local greening contributions can significantly improve quality of life. A portfolio of projects is defined in the district scale (zoom-in), while coherence with the broader urban fabric, whether blue, green or grey, is maintained (zoom-out). In this way, C2G achieves cross-scalar ecological connectivity. Ultimately, each city will develop context-specific planning guidelines and nature-inclusion strategies that will be turned into “Design solutions for blue-green-grey infrastructure with biodiversity net-gain”. Demonstrators will apply these solutions with citizens participating along the NBS life cycle, from vulnerability assessments in the early phases through to placemaking activities during implementation. This innovative participation approach ensures that interventions maximise perceived value and minimize trade-off risks (e.g. changes in streetscape uses). Satisfaction assessments shall serve as a validation of the success of the co-design approach.

The HARMONIE project takes a holistic approach to support informed policy- making by improving AP and noise monitoring, modeling, and forecasting as well as by providing tools to assess the health impact of actions on VP and the impact of actions in the long run on economy and sustainability of policies. The consortium will work in pilot cities to: 1) Enhance environmental monitoring and modelling by identifying key harmful variables. 2) Assess citizen exposure based on urban demographics, mobility, and vulnerability factors. 3) Evaluate health effects, both at the individual level (based on Digital Twin Lungs) and at the population level (computing mortality and morbidity). These components will be tested in real-world city scenarios, prioritizing pollution-abatement strategies. The methodology includes two key approaches: ● PILOTS: Data collection from Gävle (GAV), Sarajevo (SRJ), Lausanne (LAU), Barcelona (BCN) city and province, and Barakaldo (BRK), identifying vulnerable populations, monitoring pollutants (AQ & noise), and analyzing related health outcomes. ● DIGITAL TWIN: A Citizen-Centric Digital Twin (CCDT) will visualize pollution hotspots, engage citizens through interactive platforms, and integrate a social dynamics model to assess both health and healthcare system impacts under different scenarios. HARMONIE will enable ‘What-If’ scenario simulations within the CCDT, allowing policymakers to benchmark strategies and select optimal interventions. To ensure long-term impact, the project will integrate developments into existing city infrastructures, enhancing policy communication and decision-making with cutting-edge digital tools. By integrating community-driven data, What-If scenarios, and behavioral insights, it helps overcome psychological and social barriers to zero-pollution initiatives. Through dynamic simulations and feedback mechanisms, it engages citizens and institutions to develop actionable strategies tailored to urban communities.
