Climate change has increased the frequency and intensity of floods across the globe. As recent severe events in Italy, Brazil, Croatia, the Democratic Republic of Congo, Indonesia, Malawi, the Philippines, Somalia and Western Australia have shown, floods affect nature and society, leaving communities, cities and entire regions devastated. Jointly produced by United Nations University institutes in Germany (UNU-EHS), Belgium (UNU-CRIS), and the Netherlands (UNU-MERIT), a new report provides five key recommendations for strengthening climate resilience based on lessons from the 2021 floods in Western Europe.
