Development and Climate Change in the Mekong Region Case Studies edited by Chayanis Kri�asudthacheewa Hap Navy Bui Duc Tinh Saykham Voladet Contents i Development and Climate Change in the Mekong Region ii Development and Climate Change in the Mekong Region Stockholm Environment Institute (SEI) SEI is an international non-profit research and policy organization that tackles environment and development challenges. SEI connects science and decision- making to develop solutions for a sustainable future for all. SEI’s approach is highly collaborative: stakeholder involvement is at the heart of our efforts to build capacity, strengthen institutions and equip partners for the long-term. SEI promotes debate and shares knowledge by convening decision-makers, academics and practitioners, and engaging with policy processes, development action and business practice throughout the world. The Asia Centre of SEI, based in Bangkok, focuses on gender and social equity, climate adaptation, reducing disaster risk, water insecurity and integrated water resources management, urbanization, and renewable energy. SEI is an affiliate of Chulalongkorn University, Thailand. SUMERNET Launched in 2005, the Sustainable Mekong Research Network (SUMERNET) brings together a network of research partners working on sustainable development in the countries of the Mekong Region: Cambodia, China, Lao PDR, Myanmar, Thailand and Vietnam. The network aims to bridge science and policy in the Mekong Region and pursues an evolving agenda in response to environmental issues that arise in the region. In the present phase of its program (2019–27), SUMERNET 4 All, the network is focusing on reducing water insecurity for all, in particular for the poor, marginalized and socially vulnerable groups of women and men in the Mekong Region. The network aims to produce evidence- based research on regionally relevant water issues and engage with policymakers, local communities and vulnerable groups across the region. SUMERNET 4 All research comes under these three themes: (1) water access, rights and allocation in times of water insecurity; (2) governance and management of water-related disaster risks; (3) transboundary interactions with water systems.
