Australasia’s leading landscape scientists are in town this week for the annual Australia New Zealand Geomorphology
Group’s (ANZGG) biennial conference.
The five-day gathering running February 12-16 is expected to attract up to 200 people, and includes presentations,
discussions, workshops and field trips all focused on the theme for this year, Geomorphic Disturbance Recovery. There is
also a public forum that anyone is welcome to attend.
Gisborne District Council principal scientist Dr Murry Cave said it’s exciting to have such highly regarded experts in
the region.
He will also be a keynote speaker at the event.
“These are the best on landslides and land management from Australia and New Zealand and include some world-class
experts.
“They will learn and take their experiences away and apply it elsewhere but more importantly, I hope they will inform
the decision-makers when they are considering land use changes within the Gisborne region in the future. That is a
critical component for us.”
Dr Cave said it was widely recognised that changing land use is not going to be easy and will certainly take a lot of
work.
Geomorphologists have long had a special interest in the landscapes of the East Coast, especially given the region has
some of the highest rates of sediment generation and movement per unit area in the world. That has led to
ground-breaking research and multiple field trips over decades.
While the East Coast is something of a geomorphologist's dream, to others, it is more of a nightmare scenario as the
lived realities of flooding, erosion, and sedimentation issues wreak havoc.
The feedback from local groups at the community forum will highlight the local, national and international work that has
been undertaken to look after the landscapes and ecosystems of the East Coast region.
“This will give them a chance to understand the bigger picture as to what actually happened in the 2023 storms.”
In the Waimata Catchment alone there were around 14,000 landslides and Dr Cave estimates the regionwide number could be
as high as 100,000.
“We have been here before in Bola when we made land use changes and planted lots of pine trees. We have now learned more
and it is time to reconsider what is the most appropriate land use.”
The field trips take conference attendees around the East Cape, to the Waipaoa River, Wainui Beach and Mahia, as well as
into parts of Bay of Plenty, Hawke’s Bay, Manawatu and Kapiti Coast.
The gathering is the first big technological conference to be hosted in Tairāwhiti since 2018 and while Cyclone
Gabrielle was the trigger that saw the group head to the provinces, Dr Cave is hopeful good will come from it.
Anyone keen to attend the free community forum on Tuesday from 7pm-8.30pm at Lawson Field Theatre should register their
