This document summarizes an expert workshop on adaptation that took place on June 18/19, 2014. The majority of OECD countries have developed national adaptation strategies or plans. At the workshop, participants discussed tools and methods used for adaptation planning and prioritization, including expert judgement, stakeholder engagement, cost-benefit analysis, and multi-criteria analysis. Challenges in adaptation planning include long time horizons, uncertainty, and data availability. The workshop aimed to discuss best practices and help countries prioritize adaptation measures.

Adaptation strategy / Plan
Identification of specific policy measures to support
adaptation
Prioritisation of policy measures
Timetables for the implementation of adaptation
measures
4. What evidence influenced the choice of
measures?
• Expert judgement and involvement of stakeholders are the most widely used
techniques for prioritisation
• Limited uptake of cost-benefit / cost-effectiveness tools

Mainstreaming adaptation into
policy-making and project appraisal
Adaptation project appraisal
• Examples of innovative and sophisticated
treatment of uncertainty – e.g. TE210
• Focus of existing efforts to date.
Adapting policy and project appraisal
• First initiatives: “green” CBAs (UK), regulatory
impact assessments for regulations (Austria);
• Need for pragmatism, balancing rigour with
accessibility;
• Compatibility with existing systems.

9. Challenges: complexity of adaptation planning
methodological: long time-horizons, uncertainty, deficiencies in
quantification of costs and benefits of adaptation, lack of a
common metric
practical: uneven data availability
Methodologies:
climate impact assessments, CBAs, NAPAs, …

11. • M&E currently behind planning & implementation
Implementation is at an early stage, but growing body of practice
to draw upon
• Framework for M&E in adaptation will help to
assess progress in adaptation by business, government and
communities
provide public decision-makers with a body of information
monitor changes in vulnerability to climate risks through the
compilation of quantitative data on trends
facilitate mid-term adjustments
