Trees4All is a project to enhance climate resilience, improve community livelihoods and restore forest ecosystems in Nan province, Thailand. With financial support from a crowdfunding campaign, smallholder farmers in Nan plant native tree saplings and nurture them. The project is supporting a move away from single-crop monoculture into diversified plantations in the Chao Phraya River watershed, the largest watershed in Thailand. In doing so, it also helps build sustainable livelihoods through future income from the mature trees and their harvests.
