Multitemporal analysis of wetlands in the city of San Cristóbal de las Casas, Chiapas using Sentinel-2 scenes (2016-2022). Rev. Geog. Amer.

Wetlands provide various ecosystem services, thanks to their hydrological, biochemical and biological processes, which makes them fundamental ecosystems for the earth. Despite their importance, they are threatened, mainly in urban areas due to their accelerated population growth and various anthropogenic activities. In this study, remote sensing techniques are used to analyze the loss of wetlands in the city of San Cristóbal de las Casas, Chiapas, Mexico between 2016 and 2022 using Sentinel-2 multispectral scenes. Wetland areas decreased, mainly due to the transition to urban areas and agricultural soils, with a loss of 84.42 ha and an annual rate of change of 2.58% over a six-year period; without the implementation of sustainable development policies, these ecosystems could disappear and with them the ecosystem services they provide.

Palabras clave : Wetlands; Remote sensing; Sentinel-2; Land Cover Change.
