STUDY ON THE HYBRID OF GREEN AND GRAY INFRASTRUCTURES

Abstract

 In the early stage of the introduction of the concept of green infrastructures to Japan, concrete or steel structures were named gray infrastructures, and considered as the exact opposite concept against green infrastructures. However, appropriate combination based on the consideration of the each character of green and gray infrastructures is recently expected to create new values that will lead safe and sustainable land.

 Based on the background above, the task committee for the hybrid of green and gray infrastructures carried out the extensive study on the hybrid (combination and fusion) of green and gray infrastructures from June 2018 to May 2019. This report shows the summary of the activities of the task committee.
