Half of ASEAN peoples already live in urban areas and a further 70 million people are expected to live in the regions urban areas by 2025. Creating sustainable and liveable cities in ASEAN will be crucial to narrowing the existing development gaps, strengthening resilience, promoting innovations, improving well-being, and enhancing connectivity among ASEAN peoples. The ASEAN Sustainable Urbanisation Strategy (ASUS) consists of seven priority sub-areas and eight priority actions identified based on the analysis of key trends impacting urbanisation in ASEAN and stocktake of existing actions related to sustainable urbanisation. As part of ASUS, two accompanying toolkits are also available to assist local governments in ASEAN to advance sustainable urbanisation in their cities. The first toolkit, aims to provide cities with a practical guide for how they can prioritise key sub-areas of sustainable urbanisation (and associated actions) on which to focus. The second toolkit, provides implementation templates for 8 priority actions that cities can then customise to their specific contexts.
