The purpose of this technical report is to clarify the damage status of coffee trees, the factors that cause damage, and the factors that suppress damage by Typhoon No. 6, and to present countermeasures against the typhoon.The research target is a coffee farm located on flatland in the northern region of Okinawa Prefecture, which has been planted for more than 10 years, mainly using windbreaks.Researchers went to coffee farms, conducted interviews with farm owners, and conducted field surveys.As a result of the verification, we were able to show the following three points as typhoon countermeasures for coffee farms.The first point is to plant windbreak forests and fences.It is important to narrow down the farmland surrounded by them and plant them densely on all sides.The second point is to consider soil hardness. It is necessary to improve the soil hardness so that the main roots and lateral roots can extend further. The third point is appropriate tree size and management. It is important to manage the trees by raising the height of the trees higher than the planting spacing, and by pruning to allow wind to pass through.
