This week for Green Desk, Mitchell talks to Environmental Scientist Sophia Olo Whaanga about coastal urupa which are being destroyed and submerged in the face of climate change. This fast growing issue is being felt by Iwi throughout the Country, as traditional papakainga and urupa were generally located at the lower levels by the sea. Sophia has been exploring various options on how to deal with the issue, working with her Iwi; te wai o hua to find solution for their urupa which is located on the floodplain on the banks of Oruarangi awa. Mitchell begins by asking Sophia about the importance of coastal areas to Maori.
