| 要 旨 | This study explores farmer’s adaptation mechanisms to climate change. We explore how farmer’s age and engagement in community activities affect crop production under extreme temperatures. By using the municipality-level data on Japanese rice production in 2001–2018, we find a nonlinear (inverted U-shaped) age effect on the relationship between temperatures and rice yields. Farmers aged 60 exhibit the most capable of mitigating yield losses from extreme temperatures, while farmers above and below this age threshold suffer significant yield declines. Such declines can be averted by reinforcing networks and relationships among farm community members through active engagement in the community. |
