Coastal planning in Aotearoa New Zealand is supported by a deep understanding of current and future coastal flooding hazards and risks.
Accelerating sea-level rise and more frequent extreme weather events expose vulnerable communities in Aotearoa New Zealand to increasingly severe and frequent coastal flooding. The estuarine areas around which many of our cities and rural communities are developed are particularly vulnerable. Current models used to support planning for adaptation to coastal change do not consider the multiple hazards affecting these areas and the impact of changing nature of the land and seabed.
The models we are developing will incorporate human-caused and natural changes into the forecasts of the multiple hazards and risks affecting our most vulnerable coastlines. Our aim is for these models to be used in managing flooding risk and planning for coastal change adaptation.
To achieve this we are working with central and local government, hapū and iwi to:
Our goal is to improve our understanding of current and future coastal flooding hazard and risk, to give decision-makers greater certainty about coastal change when planning for coastal adaptation.
Ka tautokohia te whakamahere mō te takutai moana i Aotearoa mā te tino mārama ki ngā mōrearea me ngā tūraru o te waipuketanga o te takutai moana o anamata.
Nā te tere haere o te pikinga o te pae-moana me ngā huarere taikaha e auau haere ana i whakaraerae ai ngā hapori i Aotearoa ki ngā waipuke e taikaha haere ana, e auau haere ana. He whakaraerae rawa ngā wāhi wahapū e tū ai ā tātou taone me ngā hapori taiwhenua. Kāore i te whai whakaaro ngā tauira onāianei, e whakamahia ana hei tautoko i te whakamahere mō te urutaunga ki ngā hurihanga takutai moana, ki ngā mōrearea maha e pā ana ki ēnei wāhi me te pāpātanga o te hurihanga o te āhua o te whenua me te papa moana.
Ka whakauruuru ki ngā tauira e whakawhanakehia ana e mātou ngā hurihanga i puta i te tangata, i te taiao hoki ki ngā matapae mō ngā mōrearea me ngā tūraru maha e pāpā ana ki ā tātou takutai whakaraerae rawa. Ko tō mātou whāinga kia whakamahia ēnei tauira hei whakahaere i te tūraru waipuke me te whakamahere mō ngā urutaunga hurihanga takutai moana.
Hei whakatutuki i tēnei kei te mahi tahi mātou me te kāwanatanga ā-motu, ā-rohe hoki, ngā hapū me ngā iwi ki te:
Ko tō mātou whāinga ko te whakapai ake i tō mātou mōhio ki ngā mōrearea me ngā tūraru o ngā waipuke takutai onāianei, o anamata hoki, kia mārama pū hoki ngā kaiwhakatau ki ngā hurihanga takutai moana i a rātou e whakamahere ana mō ngā urutaunga takutai moana.
Many marae are looking to māturanga Māori developed through generations of observations to inform their adaptation to hazards exacerbated by climate change.
