Article
Full-text available
Global migration and mobility dynamics are expected to shift in the coming decades as a result of climate change. However, the extent to which migration is caused by climate hazards, in contrast or addition to other intervening factors, is a point of debate in literature. In this study, we conducted a systematic literature review to identify and co...
Article
In the past decade, there has been growing pushback towards the idea of migration as a “failure to adapt” to climate change. Climate-related migration is increasingly viewed as an adaptation strategy rather than the consequence of failed in situ adaptation (McLeman and Smit 2006). As we move toward a more nuanced understanding of the interaction be...

Disasters cost the global economy $520 billion (USD) and drive more than 26 million people into poverty each year. Floods continue to impact the largest number of people of any type of disaster globally, having affected more than two billion people over the last decade. The primary objective of this study seeks to unpack how different methods of assessing hazards influence disaster risk assessments.
Project
The overall objective of this project seeks to support local governments in developing urban communities to incorporate climate change into flood risk assessments and mobilise knowledge to realise resilient and sustainable development. As a result of better understanding the influence of climate change on flood risk, local governments and communities can make more informed decisions on their development pathways. Increased access to flood risk assessments that forecast future changes will serve to not only reduce risk, but also prevent the creation of new risk – a growing concern. This knowledge holds potential to save lives and prevent economic losses. The project will also seek to synthesise appropriate and simplified methods that can be used to create best practice on integrating climate change into flood models. Exchange of lessons from across the selected contexts will also create understanding of how risk assessments can be mainstreamed across local government development efforts. Importantly, our approach seeks to interrogate how local governments value, use, and understand climate change models. This complimentary objective seeks to ensure that the intersection of local and scientific knowledge results in policy action for local communities.
