The collaboration with the Institute of Planning and Development (IPR) Prague focuses on forming detailed case studies centred on Prague’s urban development and security. These studies explore urban conditions, models, and operational paradigms, addressing challenges in sustainable energy, infrastructure, environmental governance, and safety and security. These meticulously developed case studies are integral components intended for inclusion in the OSCE Sustainability and Innovation City Toolbox of the project’s future stages. Initiated during a September 15, 2023, workshop, they represent the culmination of meticulous research and analysis, utilizing resources provided by the IPR Prague. Each study, meticulously crafted at regional, neighbourhood, and building scales, comprehensively examines Prague’s urban fabric, encompassing its diverse facets.
