Barwon South West Local Coastal Hazard Assessment (Phase 1) G21

The Barwon South West Local Coastal Hazard Assessment Phase 1 Project aims to build a detailed picture of existing and future coastal hazards within the region.

Adaptation to sea-level rise: Local government liability issues

This paper addresses the legal frameworks and rules about what local and regional councils in New Zealand can and cannot do to adapt to the coastal hazards associated with sea-level rise and climate change.

New South Wales community perceptions of coastal erosion and inundation

The purpose of this study was to provide an evidence-based platform that will assist local governments and coastal management professionals in the future development of suitable and effective educational strategies and programs to help improve the ability of NSW coastal communities to adapt sustainably to...

Responding to rising seas: OECD country approaches to tackling coastal risks

This report reviews how OECD countries can use their national adaptation planning processes to respond to this challenge. Specifically, the report examines how countries approach shared costs and responsibilities for coastal risk management and how this encourages or hinders risk-reduction behaviour by households, businesses and...

A pressure release valve? Migration and climate change in Kiribati, Nauru and Tuvalu

This report examines migration opportunities, projects future migration numbers from three Pacific microstates, and reports on fiscal and economic impacts and the likely impact of a hypothetical one-off environmental disaster on migration options.

Climate change: the cascade effect

Climate change impacts and implications propagate as cascades across physical and human systems, compounding to form multiple impacts across sectors. Such effects arise because of the interdependencies between natural and socio-economic systems as they change and from feedback loops that occur between them. As such...

Fact Check: Is the Pacific island nation of Tuvalu growing, and not sinking, as Craig Kelly says?

Caught on tape mocking "lefties" for exaggerating the effects of climate change, Liberal MP and climate sceptic Craig Kelly has claimed that Tuvalu is not sinking beneath the seas but, according to the scientific literature, growing.

Preventing disaster in the Pacific Islands: the battle against climate disruption

The effects of global warming and climate disruption are only two of a series of issues facing Pacific Island nations. Increasing GHGs and planetary temperatures, rising sea levels and extreme weather events are potentially catastrophic for these low-lying islands.

Addressing the challenges of climate-induced migration and presenting future adaptation strategies to enable stronger cooperation between Australia and its Pacific neighbours

This paper analyses the role of industrialised countries, specifically Australia and New Zealand, and their efforts and policies aimed at assisting vulnerable Pacific island communities over any future climate-induced migration.

Global and regional sea level rise scenarios for the United States

This publication reports on the production of gridded relative sea level (RSL, which includes both ocean-level change and vertical land motion) projections for the United States associated with an updated set of GMSL scenarios.

Investigation into the impact of climate change on seawalls

There are over 90 kilometres of seawalls, levees, and associated drains within the South Gippsland Shire and Wellington Shire Council. Most of these were constructed or re-constructed during the 1950s to the 1970s to provide protection from what was then considered to be the highest...

Field and numerical investigations of wave transformation and inundation on atoll islands

Field data were collected on Fatato Island, Funafuti Atoll, Tuvalu, to understand contemporary wave transformation processes on a previously unstudied atoll. Subsequently, a fully nonlinear Boussinesq model was used to simulate wave processes on Fatato and other reefs with variable morphology to evaluate the impact...

Decision making in the face of the rising tide

The inexorable rise of sea levels as a result of runaway global greenhouse emissions is beginning to gain traction as an issue for both the Australian federal government and coastal planning authorities. This paper reports on research designed to develop a tool to assist local...

Climate change, sea level rise and coastal subsidence along the Gippsland coast

The impacts of climate change are complex, difficult to predict, yet too far-reaching to ignore. This report outlines potential threats to assets and infrastructure in Gippsland and address issues like erosion and sand transport.
