noun
adoption program
A program where individuals or groups 'adopt' a public resource (forest, highway, park, etc.) to help maintain or clean it. Common in environmental and community contexts.
この森林はアダプトプログラムによって地域住民が管理している。
This forest is managed by local residents through an adoption program.
高速道路のアダプトプログラムに参加して、定期的に清掃活動をしています。
I participate in the highway adoption program and do regular cleanup activities.
From English 'adopt program' or 'adapt program', though the intended meaning is 'adoption program'. The variation in spelling (アダプト vs アドプト) reflects different transliterations of the English word.
