Potential examples: ecosystem service payments – risk manages by offering immediate financial capital/relief, mitigates by reducing emissions, and adapts by creating incentives/opportunities to diversity away from just agricultureby creating incentives/opportunities to diversity away from just agriculture

CASE 2: Disjointed adaptation (win‐win)

Progressive adaptation (transformational
Example: subsidies that would lower emissions and give farmers extra financial capital to invest in higher production (risk management and mitigation, but not significant long‐term adaption
(transformational change)

CASE 3: Disjointed adaptation (no win‐win)
Risk management(coping)
Progressive adaptation

(coping)(transformative change)Trade‐offs
e.g.) Taxing fertilizers and pesticides –mitigates at farmer’s cost
Trade‐offse.g.) Occupational change from agricultural to industrial work–
Mitigation
farmer “adapts” at potential cost to environment
