Planting methods for windbreak forests and windbreak fences at Okinawa coffee farms

Abstract

This technical report presents the planting methods of windbreak forests and windbreak fences for good coffee cultivation, and verifies the effect of these planting methods.We surveyed two coffee farms located in the flatlands of the mountainous area in the northern part of Okinawa Prefecture, where windbreak measures were taken by planting trees. We visited a coffee plantation, interviewed the owner of the plantation, and conducted a field survey. Then We also verified the effectiveness of windbreak forests and windbreak fences using an anemometer. The windbreak forest and the windbreak fence have been planted for about 20 years and 9 years, respectively, and they are growing well at the time of the survey. And they contribute to the good cultivation of coffee. Furthermore, the results of the wind speed survey showed that the wind speed was weak compared to the place without the windbreak forest, and the effect was shown. Coffee production in Okinawa Prefecture is expected to grow further in the future, and it is believed that planting windbreak forests and windbreak fences will make it possible to protect against the wind.
