Environmental questions are at the heart of many development dilemmas in Southeast Asia. New actors and technologies, changing domestic politics, policies, and economies - as well as shifting geopolitical contexts, are remaking nature-society relations in the region. A failure to address transnational environmental challenges could not only undermine ASEAN’s legitimacy but also have drastic consequences for the region’s security and its political and economic stability. In addressing these questions in Work Package 1 (WP1), we are particularly concerned with contested knowledges of “the commons” and competition over resources. We consider the environment as a driver of processes of regional integration, but also of conflicts between various actors in the region. Our research focuses on three environmental contexts namely: sea; rivers; and air. In addressing all three our emphasis is on the transition to a low-carbon economy. The aim of this paper is to present the theoretical framework of our work as well as the three main strands of our research. In the first section, we explain our understanding of the concept of ecological knowledge. This is followed by a presentation of our methodological approaches, while the last section presents the individual research projects in the WP, arranged in three modules.This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement N°770562
