The study on Transboundary Disaster Risk Assessment and Scenario Planning for Tropical Cyclone and Droughts in the ASEAN Region demonstrates the potential impacts of tropical cyclones and drought in the ASEAN region under various climate change scenarios and to make recommendations for the ASEAN Member States to enhance disaster risk management actions, in line with the ASEAN Agreement on Disaster Management and Emergency (AADMER) Work Programme 2021-2025.

The Intergovernmental Panel on Climate Change concluded in its Sixth Assessment Report1 that compound heatwaves and droughts were projected to become more frequent, including concurrent events across multiple locations, while tropical cyclones were also projected to intensify in the future. The study has developed climate change projection scenarios for the ASEAN region and integrated them into transboundary disaster risk scenarios. The study focused on three ASEAN Member States - Cambodia, the Philippines and Viet Nam, while considering tropical cyclones and droughts for the transboundary risk scenarios.
