The ‘Harnessing Data for Democratic Development in South and Southeast Asia’ project currently being implemented by LIRNEasia is focused on data policy ecosystems in South and Southeast Asia taking into account both formal and informal policy and practice. The project also aims to expend the community of practice of Asian Data for Development practitioners and enhance the capacity of actors to participate in policy making processes and evidence-based policy influence related to data. Data governance ecosystems are made up of policies, laws, practices, behaviours and technologies that govern data. Ideally, a data governance system protects rights, enables innovation, improves transparency, and ultimately brings about democratic, inclusive governance. There are many existing and new such policies, laws and practices and tensions can arise when balancing conflicting needs.
