Welcome to the IDRiM Podcast

We are in a rapidly evolving world, meaning that the need for platforms that engage, educate, and empower society has never been more apparent. A podcast tailored to the interests and concerns of our community not only serves as a beacon of information but also fosters a sense of belonging and understanding among its listeners. By delving into diverse topics ranging from climate change and meteorological disasters to Natech disasters and terrorism, such a podcast has the potential to become a powerful tool for positive social change. In this age of digital connectivity, where voices from all corners of society yearn to be heard, the creation of a podcast offers an unparalleled opportunity to amplify junior researchers’ voices, speak meaningful dialogue, and inspire collective action.

This podcast series is going to run in a way that every Tuesday, there will be a new episode focusing on different aspects of the disaster, whether it be a recap of this month, whether it be about what we do like a documentary episode, whether it be asking students to see research about their career development, or even just asking PhD students who have just graduated to their research.

Title: IDRiM Podcast #45 “Interception reduction from deforestation and forest fire increases large-scale fluvial flooding risk”

Abstract:

Catastrophic flooding has been noted to occur with greater frequency following deforestation, but limited observations have been available to test this connection over large spatial scales. Here we used the data of mega forest fires impacting a region of 25,000 km2 in Australia exhibiting rapid loss in forest canopy, where the runoff generation has been carefully observed with minimum anthropogenic influences for more than half a century. This provides a unique opportunity to assess the impact of the forest canopy loss on large-scale fluvial flooding. A state-controlled hypothesis test, with the climate and watershed states controlled to enhance robustness, shows a statistically significant increase in annual maximum flows resulting from the forest loss treatment. The reasoning for this natural experiment is that the forest loss impact on the interception potential of forest canopy, fallen leaves, and root-zone soils in wide region could have a recognizable impact on the fluvial flood.
