2.7.5. Contribution of DAFs in Adaptation to Integrated Climate Change Decisions
on Balancing Mitigation and Adaptation
Information generated in applying DAFs in sectoral and regional climate impact
assessment studies is oriented primarily toward decisionmakers who have the
mandate to initiate and implement public policies to reduce future adverse impacts
of climate change. Just the attempt to integrate adaptation options into selected
DAFs would force analysts to think comprehensively and achieve internal consistency,
to consider broader factors beyond the influence of sectoral or regional stakeholders.
Even though a comprehensive CBA or DA remains difficult to develop, the overall
quality of the impact assessment improves.
A second, equally important use of these results is to help define GHG mitigation
objectives. National and regional positions at global negotiations on long-term
climate stabilization targets (with respect to anthropogenic forcing) apparently
are influenced by perceived risks involved in climate change as well as net
damage remaining even after plausible and affordable adaptation options have
Admittedly, it is a difficult task to formulate impact/adaptation studies properly
in any DAF. This explains the modest progress in the field since the SAR. Regional
and sectoral chapters in this volume review a small number of DAF applications,
whereas there was hardly any application on which to report in the SAR.
