Abstract

Fresh water, in sufficient quantity and of adequate quality, is indispensable for all aspects of life and fundamental for sustainable development. It is precisely this incalculable value, from the social, economic, environmental and biological point of view, that makes it necessary to follow the behavior of water-related ecosystems, and, with it, safeguard the provision of freshwater services to society and our planet by anticipating droughts and floods. To this end, as a section of goal 6.6, of Sustainable Development Goal 6 (SDG 6), indicator 6.6.1 specifically allows monitoring changes in the extent of water-related ecosystems over the years. The present work was aimed at evaluating the spatio-temporal variation of water-related ecosystems in the southeastern sector of the Republic of Cuba during the dry and rainy stages in the years 2010, 2016 and 2020 applying remote sensing techniques. As a result of the application of remote sensing techniques, it was evidenced that, with respect to the baseline of comparison, the mapped ecosystems related to water undergo significant changes in terms of their extension in the subsequent periods analyzed.
