RECEIPT WEBINAR | Coastal flooding-induced displacement caused by tropical cyclone Idai and the role of anthropogenic climate change - Benedikt Mester
Extreme weather events often trigger massive population displacement. At the same time, the frequency and intensity of such events is affected by anthropogenic climate change. However, the effect of historical climate change on displacement risk has not been quantified. Here, we show how displacement can be partially attributed to climate change, using the example of tropical cyclone Idai hitting Mozambique in 2019. We estimate population exposure to flooding following Idai’s landfall, using a combination of storm surge modeling and remotely sensed flood extent and depth, for factual (climate change) and counterfactual (no climate change) mean sea level and maximum wind speed conditions. We find that enhanced cyclone intensity has played a larger role than rising sea level in raising exposure to flooding. Besides highlighting the significant effect climate change already has on humanitarian conditions, our study may also serve as a blueprint for event-based displacement attribution.

H2020 RECEIPT – Remote climate effects and their impacts on European sustainability, Policy and Trade
WP5 International cooperation, development and resilience
RECEIPT aims to provide relevant and quantitative information on the European risks from remote global climatic features using a novel scientific storyline concept that maps representative connections between European socio-economic activities and remote climatic hazards. In WP5, we are assessing how climate variability and change can undermine development progress, competitiveness, stability and resilience of countries with which the EU maintains strategic partnership relations.

Speakers

Benedikt Mester
M.Sc. @Potsdam Institute for Climate Impact Research - PIK
Benedikt Mester holds a Master's degree in environmental engineering and is currently pursuing a PhD at the Potsdam Institute for Climate Impact Research (PIK), Germany. His research focuses on disaster-induced displacement risk in the context of climate and socio-economic change using numerical models, remote sensing and data science techniques.
Domenico Bovienzo
Researcher @Euro-Mediterranean Center on Climate Change (CMCC)
Domenico Bovienzo is a research member in the Risk Assessment and Adaptation Strategies - RAAS Division at CMCC Foundation. He holds a Master of Research in “Science and Management of Climate Change” from Venice Ca’ Foscari University, a MSs in Political and International Sciences from the University of Siena and a BSc in Economics from the University of Verona. In his academic career, he was involved in the Erasmus for Studies program at KU Leuven (Belgium) and he took part at the Best Water Summer School in Siena. Domenico is an Independent Research Fellow at the Institute of European Democrats (Belgium) and he previously collaborated with Arciconfraternita di Misericordia di Siena (Italy) and Azienda Vinicola Farina (Italy). His main research interest is on the relationship between Climate Change and Migration and its complex dynamics.
