2nd Mekong Climate Change Forum Adaptation to Climate Change in the Transboundary Context 6-8 October 2014 Siem Reap, Cambodia Forum Book of Abstracts 6-8 October 2014 | Siem Reap | Cambodia 1 FORUM BRIEF Home to about 60 million people, the Lower Mekong River Basin (LMB) has experienced rapid development, urbanisation and population growth which have adverse effects on the Mekong resources and populations who depend on them. Climate change has increasingly placed burdens on the environment and the people. For example, rising temperatures and unpredictable rainfall are bringing drought to some areas and flooding to others. The Mekong Delta is experiencing sea level rise and increasing saltwater intrusion to its ecosystems and farmland. Extreme weather events such as typhoons are increasing in frequency and severity, destroying homes, infrastructure, livestock and crops. Adaptation measures can help vulnerable communities and governments to better deal with such changing climate conditions and thus reduce consequences on people’s livelihoods, ecosystems and the economy. The Mekong River Commission (MRC) is holding a three-day forum for all stakeholders, including government officials, academics, experts, representatives from river basin organisations, the Development Partners of the MRC, development agencies, civil society and the private sector, to share and exchange their knowledge, experience and progress in undertaking measures to adapt to changing climate. This is the second MRC regional platform on climate change following the first forum held in February 2009 in Bangkok, Thailand. This 2nd Mekong Climate Change Forum will explore the following topics: • State of knowledge on climate change and climate change impacts and vulnerability in the Lower Mekong Basin; • Climate change adaptationin the Lower Mekong Basin: Policies, strategies and actions on the ground; • Transboundary adaptation needs and approaches in the Lower Mekong Basin; and, • A synergy between the national and transboundary adaptation. The Forum aims to achieve the following results: 1. Enhanced understanding on up-to-date approaches and actions to address transboundary impacts of climate change in the Lower Mekong Basin; 2. Increased dialogue, exchange of knowledge and experience within the Mekong and with other transboundary river basins; 6-8 October 2014 | Siem Reap | Cambodia i 3. Input to the preparation of the 1st Report on Status of Climate Change and Adaptation in the Lower Mekong Basin; 4. Input to the preparation of the Mekong Adaptation Strategy and Action Plan; and, 5. A forum proceeding which summarises knowledge and experiences discussed and shared during the Forum. Accordingly, the first day of the Forum, th6 October, after setting the scene with the introduction on topics of climate change adaptation (CCA) at international and regional scales, up-to-date findings related to climate change and adaptation in Asia and the LMB will be presented. In the afternoon, the focus lies on climate change impacts, vulnerabilities and adaptation in water-related sectors in the Lower Mekong Basin, in which the parallel sessions highlight topics related to flood and drought, agriculture and fisheries, and ecosystems and biodiversity. The last plenary session of the day will define principles of cross-sector adaptation and transboundary adaptation with concrete examples from the Danube Basin and the Iberian Peninsula. The second day, Tuesday 7th October, is opening with the presentation of national and transboundary adaptation strategies and action plans in the LMB, which will provide foundation for further discussions in the following panel session on synergies between the national and transboundary levels with regard to adaptation strategies and action plans. The focus of the parallel sessions is on approaches, methodology and good practices related to flood and drought, agriculture and fisheries, and ecosystems and biodiversity. The last parallel sessions will present various good practices and lessons learnt in LMB, regarding (i) mainstreaming adaptation into development, (ii) adaptation in practice and (iii) replication and upscalling. The third day, 8th October, is closing the event with the plenary panel on ways towards the Mekong Adaptation Strategy and Action Plan. We hope you enjoy the forum and have a pleasant stay in Siem Reap, the town with the land of wonder of the Angkor Complex and the memorable culture and tradition of Cambodian people. ii 2nd Mekong Climate Change Forum Table of Contents FORUM MODERATOR AND FACILITATOR 1 SESSION 1: OPENING PLENARY Remarks from MRC Development Partners 7 KEYNOTE 1: Adaptation to climate change in a transboundary context: Setting the scene “lessons for practical adaptation management planning” 8 KEYNOTE 2: Adaptation to climate change in the context of the Lower Mekong Basin 10 SESSION 2: PLENARY SESSION 15 2.1 Status of climate change and adaptation in Asia from the IPCCS 5th Assessment Report 12 2.2.
