PROSPERITY will: 1. Produce a culture shift in terms of environment for SUMPs in member states and in the organisational culture of transport planning in city authorities. 2. Get ministries and national agencies to play a national leading role on SUMPs, as in many member states these are the organisations from which cities take their main direction; where ministries are already playing this role, to support and strengthen their approach. 3. To provide mechanisms and tools for Ministries to take this lead role. 4. Analyse clearly the problems of (lack of) take-up of SUMPs – to understand from cities themselves why they are not taken up and then to help cities to address these barriers. 5. Extend the existing 25-county EU-SUMP-network with at least two more countries 6. Get more cities to take up effective high quality SUMPs – through cities’ involvement in the project and indirectly through more cities hearing about SUMPs in their country. 7. Ensure that these SUMPs contain and will lead to implementation of a broad range of innovative sustainable transport measures. 8. Build cities’ capacity to develop and implement SUMPs that genuinely reflect the spirit of the EU SUMP Guidelines, rather than being mandatory documents to fulfil a requirement linked to major transport infrastructure. 9. Deliver a measurable impact. The core concept of PROSPERITY is bringing ministries into the project, which will significantly enhance the visibility of the project at the national level and therefore increase numbers of cities active on SUMPs. Thus PROSPERITY will ensure that more cities commit to SUMPs that are in line with the EU SUMP Guidelines and that include a broad range of innovative measures. This will generate a high leverage factor, especially in regions and cities where take up is so far low and the impacts from transport are severe – therefore the majority of PROSPERITY activities is in such regions and cities - thus in southern, central-eastern and eastern Europe.

Based on a detailed mapping of urban challenges and relevant nature-based solutions (NBS), Nature4Cities aims at developing complementary and interactive modules to engage urban stakeholders in a collective-learning process about re-naturing cities, develop and circulate new business, financial and governance models for NBS projects, as well as provide tools for the impacts assessment, valorisation and follow-up of NBS projects. The different modules are: • a database of generic NBS and associated environmental, economic and social performances • an observatory of NBS projects best practices / case studies • a set of innovative business, financial and governance models for the deployment of NBS in a range of different contexts, together with a tool to help urban stakeholders identify eligible models regarding their NBS project contexts • a NBS project impact assessment toolbox providing capabilities for environmental, economic and social impacts evaluation at different stages in the project development cycle from opportunity/feasibility studies to design steps and project follow-up). This toolbox will built on a range of tools, from generic indicator-based assessment for early project stages, down to detailed modelisations of NBS behaviors. These modules that already have a proper purpose on their own, will furthermore be integrated in a NBS dissemination and assessment self-learning platform [N4C Platform] to assist NBS project developers along the entire life cycle of their projects from opportunity studies and project definition down to performance monitoring. Nature4Cities indicators, methodologies, tools and platform will be field tested in real working environments and on real nature-based solution projects and developments in selected cities in Europe, which will be partners of the project and engage their technical urban and environmental planning teams.
