While floods and other natural disasters affect hundreds of millions of people globally every yea...r, a shared methodological approach on which to ground impact valuations is still missing.

Understanding ongoing trends at local level is fundamental in research on climate change. However..., in the Global South it is hampered by a lack of data. The scarcity of land-based observed data can be overcome through satellite-derived datasets, although performance varies according to the region.

Urban flooding has become a serious issue in most Chinese cities due to rapid urbanization and ex...treme weather, as evidenced by severe events in Beijing (2012), Ningbo (2013), Guangzhou (2015), Wuhan (2016), Shenzhen (2019), and Chongqing (2020).

Floods have recently become a major hazard in West Africa (WA) in terms of both their magnitude a...nd frequency. They affect livelihoods, infrastructure and production systems, hence impacting on Sustainable Development (SD).

In the last decades, the Sahelian area was hit by an increase of flood events, both in frequency and in magnitude. In order to prevent damages, an early warning system (EWS) has been planned for the Sirba River, the major tributary of the Middle Niger River Basin. The EWS uses the prior notification of Global Flood Awareness System (GloFAS) to realize adaptive measures in the exposed villages.
