In this paper was calculated the return period of coastal floods for each of the coastal settlements that report this extreme event in the Cuban archipelago, based on the period 1901-2020. The chronology and classification of coastal floods for each province was used, as well as the Poisson distribution and the χ² goodness of fit test. It is concluded that the Poisson distribution was suitable in all cases for the significance level of 5%; while the greatest hazard is presented by Havana, Baracoa and the settlements of the Gulf of Batabanó in which the occurrence of a flood event is expected at least once every three to five years.

The aim of this paper is to present a panoramic view of the impact of climate change on the Cuban Southeast. It discusses the principal threats and risks affecting coastal areas, and describes the most recent and pertinent results of scientific research carried out with the aim of tackling climate change in such areas. Programmes that have been adopted in order to identify and implement solutions regarding Integrated Coastal Zone Management and the management of human settlements are also presented. Such programmes aim to reduce vulnerabilities resulting from serious natural threats, progressive sea-level rise or from the effects observed through models of upwelling in the case of hurricanes of different categories. This paper concludes that climatic change in the Cuban Southeast is a process beyond doubt, and it is currently being confronted as a matter of priority; more than ten programmes have already been put in action, involving various collaborating institutions.
