Governance of Adaptation

• Need to understand autonomous adaptation and drivers of adaptive capacity to design effective adaptation policies• Framework• Case Study

Framework Goals• Identify which socio-economic, biophysical,

and perceptional factors enhance adaptive capacity

• Identify current gaps in research methodology and important next steps for adaptation research

Methods• Searched for studies that assess the socio-

economic, biophysical, and perceptional factors that are associated with increased adaptive capacity • ISI Web of Knowledge• 200 studies that were most cited• Span the disciplines of anthropology,

economics, geography, psychology, and social-ecology

Adaptation Research Next Steps

• Consider multiple factors in the same analysis

• Multi-disciplinary

• Explicitly consider climate as a driving factor

Household-level Adaptation• Are farmers shifting behavior based

on climate variability? • Which socio-economic, biophysical,

and perceptional factors are associated with farmers who adapt?

• Are these coping strategies adaptive?

Conclusions• Farmers alter cropping strategies based

on inter-annual rainfall variability at both local and regional scales

• Farmers with irrigation access are less likely to alter cropping strategies

• Yield is best explained by number of irrigations but is not affected by planting date

Conclusions• Framework allows us to assess:• the relative importance of various inter-

disciplinary drivers for decision-making• whether coping strategies are adaptive• whether our results are generalizeable

across a broader region
