There is increasing policy interest in the appraisal of
options, as adaptation moves from theory to practice. At the same time,
it is recognised that the appraisal of climate change adaptation
involves a number of major challenges, particularly the consideration
of uncertainty. In response, a number of existing and new decision
support tools are being considered for adaptation.
The
European Commission FP7 funded MEDIATION project (Methodology for
Effective Decision-making on Impacts and AdaptaTION) is looking at
adaptation decision support tools, in line with its objectives to
advance the analysis of impacts, vulnerability and adaptation, and to
promote knowledge sharing through the MEDIATION Adaptation
Platform. To complement the information on the Platform, a
series of Technical Policy Briefing Notes have been produced on
Decision Support Methods for Climate Change Adaptation.
This
note, Policy Briefing Note 1: Method Overview, provides a summary of
the decision support tools, their potential relevance for adaptation
and guidance on their potential applicability.
It
covers a range of traditional decision support tools (cost-benefit
analysis, cost-effectiveness analysis and multi-criteria analysis) as
well alternative approaches that more fully capture uncertainty (real
options analysis, robust decision making, portfolio analysis and
iterative risk (adaptive) management, adaptation turning points and
analytic hierarchy process). It also includes complementary tools that
can assist in adaptation assessment including social network analysis.
Additional
information on each of the methods, including case study examples, is
included in a series of
separate
Policy Briefing Notes (2 – 9).
