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.

Spelling with interpunct; sometimes used for clarity.
Rare variant with interpunct using 'adopt' transliteration.
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.
