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
