How can we develop adaptation plan?
What are the best adaptation measuresin this local area ?

We need to prevent the risks owing to climate change. It requires proper adaptation plans. Every local government should
develop climate change adaptation plan every 5 years. Some government develop plan well with lots of experts and information. However, the others have problem to make the plan because of lack of knoweldge, information, and fund. For
these reason, govenrments need a decision supporting tool for developing adaptation plan. The main purpose of the tool
is providing information & reducing fund. We divide the process of developing adaptation plan. First part is making thevision. It means which part/sector are important for the governments. We want to link this part with the existing vulnerability assessment system “VESTAP”. Second part is prioritizing the adpatation measures. We studied how to make thepriority and developed the default result which is for the national scale. If local government apply this result, they canchoose some weight and score of the criteria. Final step is showing the priorities/ranks and adaptation measure inventory. To summary, the aims of the our tool are that let the governments know which measures are needed and the information about those measures.

Make the vision of adaptation Priotize the adaptation measures
Link with vulnerability assessment tool

Selecting specific plans

Provide sufficient information using inventory

Provide priotizing tool / default result

VESTAP(Vulnerability Assessment Tool): Climate Impace Exposure + Sensitivity + Adaptation Capacity

Defineproblem1: check the score of Feasibility

Prioritizing

flooding

Check the score

PolicyDrought: Define which policies and which sectors are the bigger problem
For example, flooding is bigger probelm than drought.

3 Provide the priorities

Prioritizing: the result of MCDA and the examples ofdetailed plan for the national/ provincial/ local governments

Result 1: Criteria
1. Importance: effect on adaptation. how much this measure can reduce negative impact of climate change
2. Synergy: effect on other adaptation sector. how much this measure can reduce negative impact of other sector
3. Mitigation: effect on climate change mitigation. how much this measure can reduce greenhouse gas emission
4. No-regret: effect on non-climate change. how much this measure have benefit regardless of climate change
5. Urgency: degree not to be delayed / must be done right now
6. Cost: degree of total cost. It includes the cost of installation, operating, and maintanance
7. Feasibility: how much this measure is easy to implement institutionally without difficulty

Previous studies

The criteria are selected by referring the previous cases (UK climate impacts program, 2007; De Bruin et al., 2009;
Hallegatte, 2009). They contain the effect on the variety section (=benefit), cost and possibility.
The Feasibility (possibility) in the default result reflect the general situation. It can varies by local governmnet.
