Within this framework, NUPs are highlighted as being a primary tool for governments to articulate the implementation of such global commitments and the definition of a national vision for sustainable urban development, by engaging, coordinating and leading multiple actors across different sectors and scales. It aims to record the global advancement of NUPs as an indicator of the implementation of global agendas and to provide national governments, and other stakeholders involved in the NUP process, with more information and perspective for the successful development of a NUP. While it would be beyond the scope of a global report to provide a detailed blueprint for NUP development, as this should be tailored to national needs and aspirations, this report still highlights general opportunities, challenges, trends and best practices of NUP development at global and regional scales.
