National Adaption Plan (NAP) Process and Actions Case Studies in the Asia-Pacific Region from 2015 to 2017

NAP Process and Actions

A variety of stakeholders in each country have contributed significantly to mainstreaming adaptation into national development strategies and plans in different ways and implementing adaptation actions compatible with sustainable development. Since there are various experiences, best practices, and lessons learned from each process and action, the Ministry of the Environment, Japan compiled case studies on the NAP processes and adaptation actions in different sectors implemented in the Asia-Pacific region from 2015 to 2017 with the support of governments, NGOs, relevant multi/bi-lateral agencies, and experts. This page presents the case studies and lessons learned from studies carried out from 2015 through 2017, and processes pertaining to donors’ assistance. It is hoped this information will help policy makers and other relevant stakeholders learn the lessons and good practices of these NAP processes and adaptation actions, and utilize them in further planning and actions.

You can select the countries you want to view from a map, and can choose key elements using the checkbox regarding mainstreaming adaptation into development plans and implementing adaptation measures, as extracted from the case studies. The elements are compiled on two levels (see the figure below): the policy level and project level. Each level consists of a cycle of planning, implementation, monitoring and evaluation (M&E), institutional arrangements, and capacity building. The letters and numbers listed in the list following the search are linked with the figure below.

International Cooperation

International Cooperation on climate change impact assessment and promotion of adaptation by the Ministry of the Environment of Japan.


Projection datasetClimate Change in Asia-Outputs from GCM

The Ministry of the Environment, with the cooperation of Japan Meteorological Agency, created a climate change projection dataset with a view to performing impact assessments and drawing up adaptation measures in Japan. This dataset is composed of two types of model output: global climate model outputs and regional climate model outputs. The global climate model outputs (hereinafter referred to as “GCM data” ) are the results of calculations using an atmospheric model covering the entire world with an image resolution of about 60 km. The periods covered by the data are "20 years of the present climate" and "20 years of the future climate" (the end of the 21st century).

MOEJ and ADB agreed to share climate risk information on AP-PLAT

The Ministry of the Environment, JAPAN (MOEJ) and Asian Development Bank (ADB) held "the 3rd MOEJ - ADB policy dialogue on environment" and agreed on work program, following the signing of the extension of "Letter of Intent on Cooperation for Environment between the Ministry of the Environment, Japan and Asian Development Bank".

The MOEJ and ADB agreed to collaborate on climate adaptation strategies and share climate risk information via the Asia-Pacific Adaptation Informant Platform. *

  1. * "Asia-Pacific Adaptation Informant Platform (AP-PLAT)" will be established by 2020 by expanding the function of A-PLAT that serves as a basis for adaptation actions in Japan.

International cooperation on detailed scenario dissemination for impact assessment and development of adaptation measuresby Meteorological Research Institute/Japan Meteorological Agency

International cooperation on detailed scenario dissemination for impact assessment and development of adaptation measures

People are interested in how the climate in their area changes as a result of global warming. However, it is impossible to project such detailed local climate change with global climate models such as general circulation models (GCMs) or earth system models (ESMs) even as computer technology has advanced. Therefore, a method called dynamical downscaling is used to project local future climate conditions with regional climate models (RCMs). RCMs are applied over a limited-area domain with boundary conditions from GCM/ESM output to calculate fine climate scenarios. High-resolution climate change scenarios are a basic requirement for assessing climate change impacts, vulnerability, and risks and adapting policy making at local and regional scales.

The Meteorological Research Institute (MRI) has developed the Non-Hydrostatic Regional Climate Model (NHRCM; Sasaki et al., 2008). The MRI (Figure 1) has been conducting research collaboration on and disseminating dynamical downscaling techniques of the NHRCM with researchers from collaborating countries in the Coordinated Regional Downscaling Experiment (CORDEX), including India, the Philippines, Vietnam, Indonesia, Malaysia, and Thailand (Figure 2).

CORDEX is an initiative by the World Climate Research Programme to provide RCM downscaling technology. Such a collaborative effort on future climate projection with the NHRCM is in the best interest of collaborating countries and organizations within the Southeast Asia division of CORDEX, because dynamical regional downscaling is time-consuming, resource-intense, and the NHRCM is a state-of-the-art RCM in the world. A simplified explanation of the research collaboration is described here.
