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 a Adaptation Platform. To complement
the information on the Platform, a series of Policy Briefing Notes have
been produced on Decision Support Methods for Climate Change Adaptation.
An
overview of all the decision support tools reviewed is provided
in
Policy
Briefing Note 1:
Method Overview, which summarises each method, discusses the
potential relevance for adaptation and provides guidance on their
potential applicability. The methods considered include existing
appraisal tools (cost-benefit analysis, cost-effectiveness analysis and
multicriteria analysis), as well as techniques that begin to address
aspects of uncertainty (real options analysis, robust decision making,
portfolio analysis and iterative risk (adaptive) management). It also
includes complementary tools that can assist in adaptation assessment,
including analytic hierarchy process, social network analysis and
adaptation turning points. Additional information on each method is
presented in a
series of
separate
Policy Briefing Notes.
This Policy
Briefing Note (Note 8) provides a description of
Social Network Analysis.
It then places SNA in the context of adaptation and identifies
strengths and weaknesses. Two case studies from MEDIATION highlight
issues in applying the tool to real decision processes. More detailed
information is available in MEDIATION deliverables, and sources and
links on the MEDIATION Adaptation Platform.
