Climate change risks to property values

See the original article here

Extreme sea-levels from storms augmented by sea-level rise are potentially a threat to New Zealand’s property values and financial stability, according to a University of Otago expert.Ivan Diaz-Rainey profile.jpg

Professor Ivan Diaz-Rainey, of the Department of Accountancy and Finance, joined other prominent speakers at the Assembly of Investment Chairs’ seminar on Tuesday 29 November to discuss this year’s theme of ‘greenwashing, climate disclosures and impact investment’.

He took the opportunity to share the insights he has found 18 months into his three-year long Royal Society-funded Marsden project that partners with GNS Science, Bodeker Scientific, National Institute of Water and Atmospheric Research (NIWA) and the Reserve Bank of New Zealand.

Climate Change: NZ Banks, Homeowners Exposed to Rising Flood Risk

CEFGroup’s Director, Professor Ivan Diaz-Rainey, had an interview with NZ Heralds this Tuesday. He shared his concerns re how climate risks affects the New Zealand housing market, and how this would pose risk to the country’s economy.

Diaz-Rainey and his team are exploring the threat themselves, in the Marsden Fund-supported project that involves developing new models to test property impacts against.

Diaz-Rainey Joins RNZ Panel Discussion Including Flooding Hazards to Property

A recent NZ government report has identified dozens of communities at serious risk of flooding, with most having little protection in place to prevent flood hazards. In a recent RNZ panel, CEFGroup Director & PI of the STRAND Marsden Project, Professor Ivan Diaz-Rainey, shared his insights on what how climate change would affect property values in flood-risk areas, and what impact flooding could have on insurance and mortgage lending risk.

STRAND Marsden Project Seminar Presentations

The Green and Sustainable Finance (GSF) transversal research programme of the Institut Louis Bachelier and the interdisciplinary Energy4Climate Center (E4C, Institut Polytechnique de Paris) hosted a joint seminar 10.00am-11.30am CEST on Monday the 12th of September, at the premises of Institut Louis Bachelier.

Dr Quyen Nguyen, CEFGroup’s STRAND Marsden Postdoctoral Fellow, presented their latest research on the topic of “Asset-Level Modelling of Climate Change-Related Flooding Risk” – parts of the STRAND project. The authors highlight the importance of uncertainty estimates when they relate to high impact public-interest decision-making.

Note that the working paper has also been presented to the ITC Centre for Disaster Resilience at University of Twente this Friday (9th September), 11.00-11.45am CEST. Recording is now publicly available HERE.


Climate change risk: Why are people still buying by the sea?

Climate change is real and happening right now, but many homeowners in at-risk areas are still not thinking realistically about what it means for their properties, experts say.

The news article is available HERE.

In recent months, there has been a succession of significant floods around the country, and that follows a number of one-in-100-year floods last winter. Continue reading

Atlantis is rising: The suburb that’ll meet sea level, and thrive

The myth of South Dunedin going underwater in the next 100 years is just that, a myth. One that a scientist, community leaders and councils have tried to bust with limited success. So why are people still convinced? Sinead Gill reports.

The news article is available HERE.

When it rains in South Dunedin, it’s not just flooding people are concerned about, but what the flooding represents.

Much of the community, made up of multiple suburbs, was built on swampy terrain, now called “the Flat”. It is infamous for having the most homes 50cm or less above sea level in the whole country – more than Auckland, Wellington and Christchurch combined, according to a 2015 report.

Website Seawise tracks sea level rises and vertical land movements in New Zealand. Dr Simon Cox, a principal scientist at GNS Science, based in Dunedin, said if levels continued to rise at the current rate, parts of South Dunedin would be at or below sea level by 2050. Some 2700 homes would be at or below by 2100.
