A stone monument can sometimes be conserved by stabilizing its surviving fabric. An agricultural landscape has a different requirement: people must continue using it. Rice does not replant itself to preserve a view, and an irrigation edge does not repair itself because the surrounding hillside has heritage status. The attractive surface is the outcome of recurring work.
FAO recognized Longji within the southern Chinese rice-terrace GIAHS system in 2018. That designation concerns agricultural heritage, not an inscription on UNESCO’s World Heritage List. The subject includes knowledge, land use and livelihoods. Retaining a picturesque outline while removing the circumstances that make cultivation worthwhile would preserve only a small part of what is important here.
