udy on Climate Change Adaptive Capacity Building of Water Supply System and Monitoring and Revising of Adaptation Pathway

In order to face the challenge of climate change, many counties have developed the climate adaptive capacity building processes. Most adaptive capacity building processes start from problem identification and risk assessment, and then attempt to propose adaptation strategies to cope with climate change uncertainty. However, the monitoring, reporting and evaluation (MRE) process to adaptation strategies is also important under the high uncertainty of climate change. The Taiwan integrated research program on climate change adaptation technology (TaiCCAT), funded by the ministry of science and technology, have reviewed the adaptive processes from different countries, and proposed TaiCCAT six-steps. The TaiCCAT six-steps include (1) Identifying problems and objectives, (2) Assessing current risk, (3) Assessing future risk, (4) Identifying and assessing adaptation options, 5. Planning and implementing adaptation pathway, (6) Monitoring and modifying. The six-steps have been used by several research institutes and city/county governments to assess risk of climate change and build adaptation action plans. The framework of TaiCCAT six-steps have been constructed, but several issues are still left for in-depth discussion. The TaiCCAT six-steps is uses as the core part of this research, and the skill of information flow analysis is applied to analysis the sub-processes of six-steps from the angle of inputs, tools, and outputs of each step. In this study the improvements for six-steps are proposed after the information flow analysis. In this reaearch, three procedures are established separately to support the original processes of step 3, step 5 and step 6 of TaiCCAT six-steps: 1. GCM selection, 2. adaptation pathway building, 3. monitoring and revising of adaptation pathway. The procedure of GCM selection consists of GCM applicability ranking process for single weather station and the result of climate zonation. The weather stations in Taiwan were classified into 10 climate zones, and GCM suggestion list for each zone was generated according the result of GCM ranking for single weather station. The skill of program evaluation and review technique (PERT) was used to arrange the schedule of adaptation actions, and build adaptation pathway map for step 5. The procedures of adaptive monitoring and revising of adaptation pathway was proposed to monitor and revise implementation of adaptation for step 6. To test the precedures proposed in this study, the Touchien River water supply system is used as the study area to assess climate change risk and build adaptation capacity with TaiCCAT six-steps.
