The anthropogenic climate change is increasing water-related disaster risks such as flood and drought because most of the adverse impacts of climate change is delivered to society through water. Mitigation efforts to reduce the greenhouse gas, e.g., CO2, emission and to reduce the speed of climate change are essentially important, and at the same time, adaptation measures to reduce the vulnerability and exposure of human lives and properties from the risks exacerbated by climate change are also relevant. After the Paris Agreement of UNFCCC in 2015, all the member states are encouraged to set their National Adaptation Plans (NAPs).

The formulation of “Thailand’s National Adaptation Plan” is being led by the Office of Natural Resources and Environmental Policy and Planning (ONEP) under Ministry of Natural Resources and Environment as a plan for the implementation of adaptation measures by each ministry and agency. For supporting the NAP formulation and development of climate change measures that contribute to a resilient and sustainable society, a new research project entitled "Advancing co-design of integrated strategies with adaptation to climate change in Thailand (ADAP-T)" with international collaboration between Thailand and Japan was proposed, approved, and implemented since 2016, supported by JICA and JST under the framework of SATREPS.

ADAP-T has three piers of research, namely i) Knowledgebase of climate change, ii) Adaptation measures to climate change, and iii) Co-designing adaptation measures. Disciplines relevant for the major sectors prone to climate change, such as riverine hydrology, forest hydrology, sediment erosion, coastal erosion, urban hydrology, and agricultural hydrology are collaborating under ADAP-T, and Kasetsart University, Thai Meteorological Department, Royal Irrigation Department, and ONEP are managing the ADAP-T project in Thailand with close communication with The University of Tokyo and associated researchers in several universities in Japan.

The overall goal of ADAP-T is to support the development of a climate change adaptation strategy that can maximize the benefits of society by combining various countermeasures through dialogue with various stakeholders such as the government and citizens. These research results have been contributed to the formulation of NAP, which was compiled and published as ADAP-T Special Report 2018 and research and implementation of good practice of adaptation measures in each sector are expected to contribute to NAP guidelines which currently being developed by ONEP for policy makers. Moreover, these results and basic information on cost-benefit estimation of adaptation options in each sector based on future scenarios are integrated into a web-based adaptation simulator as a tool to assist the multilateral dialogue among citizens, policy makers, and researchers. Furthermore, it is expected that these outcomes will be expanded to neighboring Southeast Asian countries for adaptation to climate change, which is becoming increasingly necessary and important in developing countries.
