Due to concerns over the spread of Covid-19 in the world, we regretfully announce the cancellation of DIWPA International Field Biology Course (IFBC) in this year. In Japan, we are in the second wave of Covid-19 now, and we must continue to monitor the situation to conduct any events. The information of IFBC in 2021 will be announced on our website, while considering the situation of Covid-19 in the next year.
