Our interconnected world requires smart policies. Policy learning advances the professional competences of people and institutions and contributes to better policy development. Jean-Marc Venineaux set the stage by pointing out that the 7th Cohesion Report calls for further efforts to bring regions closer to each other. That requires cooperation. Placing cooperation at the heart of policy making will benefit Europe as a whole. Jason Martinez stressed that interregional cooperation was at the core of the Interreg Europe programme. Capacity building through cooperation helps regions tackle societal challenges and improve policies by sharing solutions. Interreg Europe accelerates regional development via two streams: interregional projects and the Policy Learning Platform. Projects bring regions together to identify and exchange good practices. Good practices are incorporated into regional action plans which turn them into concrete initiatives through implementation. The Policy Learning Platform goes beyond projects and disseminates lessons learnt from their exchange across Europe. The interregional learning process is like cooking: one may start with the same recipe, but success requires the right combination of experience, tradition, application and innovation. There is no magic recipe for learning, but a successful process for transferring knowledge and good practices often occurs through analyses, study trips, workshops, staff exchanges, and peer reviews. An integrated approach ensures that learning happens at different levels and delivers results. Several Interreg Europe projects - HoCare, RESET, FINERPOL and CESME - shared their learning strategy with the participants. They illustrated that there is no one-size-fits-all approach for the learning journey. Ariance Lecerf emphasised the need to spread the learning effects beyond the project to maximise the resulting impact. Communication and cooperation are very important not only within the project, but also with stakeholders. The managing authorities should be closely involved in the project and updated on its progress. Moreover, it is vital to raise awareness of the added value of interregional cooperation and ensure that all relevant public and private stakeholders are on board and understand their role in turning policy into practice. Laura Indriliunaite made similar points and introduced another initiative aimed at bringing cohesion policy practitioners together. TAIEX-REGIO PEER 2 PEER, launched in 2015, provides assistance and possibilities for exchanging experience among regional bodies managing ERDF and cohesion funds. The initiative covers three types of learning initiative: study visits, expert missions and workshops. Management and control, financial instruments, smart specialisation, public procurement and state aid have been among the most popular topics. Experience shows that learning happens not only via structured channels, but also informally via networking. Virtual tools can help, but physical meetings remain important catalysts of cooperation. Outcomes vary from concrete solutions to intangible results such as changes in mindset. Both are important.
