Jeju Batdam Agricultural System
A traditional agricultural system on Jeju Island, South Korea, based on volcanic stone walls (Batdam) that protect crops from wind, reduce soil erosion and evaporation, and promote water infiltration. With more than 1,000 years of history, it is recognized by FAO as a GIAHS for its agricultural, environmental, and cultural value.
Country:

It is a traditional agricultural system developed on Jeju Island, South Korea, based on the construction of volcanic stone walls (Batdam) around agricultural plots. Built with stones removed from the fields, these walls protect crops from strong winds, reduce soil erosion and evaporation, and promote water infiltration, enabling agriculture in a volcanic environment with adverse climatic conditions. With a history spanning more than 1,000 years, the system has been recognized by FAO as a Globally Important Agricultural Heritage System (GIAHS) for its contribution to landscape conservation, biodiversity, and traditional knowledge.

Sector:
Batdam stone walls reduce soil erosion and surface runoff, promote water infiltration and groundwater recharge, decrease moisture loss caused by wind, and protect crops from extreme weather events. They also support biodiversity by providing habitats for various species, preserve the traditional agricultural landscape, and contribute to the sustainable use of natural resources.
