Box 1: No Regrets Strategy
No regrets strategies for climate change adaptation are based on present
day actions that can be undertaken without understanding all dimensions
and impacts of climate change (Circles of Social Life 1996, IPCC 1996).
Focusing spatial planning effort on areas that are projected to remain
suitable for a focal species offers a no regrets (sensu Heltberg et al.
2009, Hoegh-Guldberg and Bruno John 2010) strategy for dealing with much
of the uncertainty associated with SDM projections. While practitioners
can aim to reduce uncertainty in the modeling process, they can also
present model outputs in ways that have the highest confidence. Where
predicted and projected probabilities of suitable habitat overlap, there
is greater certainty that the species presence will not change, and a
greater likelihood that such space will meet resource management
operational goals (Kujala et al. 2013a, Kujala et al. 2013b). In these
areas, conservation will benefit the species now, and focuses attention
on areas of the species’ projected range where SDM models have the
highest certainty. An evidence-based no regrets strategy can inform risk
management and decision making processes (Makino et al.
2015).
