Yunlin is the most important agricultural area in Taiwan. Due to the poor government policies in the past decades, the farmland pollution caused by industrial pollutants, land subsidence, chemical hazards, and pesticide hazards have occurred continuously. Therefore, the 2013 Yunlin Agri-Expo emphasizes the importance of the land ethics. The triangle logo represents the harmonious, balanced, and sustainable relationship among the people, land, and crops; the green squares of the logo represent an aerial view of scattering farm fields.
