The present study focuses mainly on knowing the current status of wetlands in the context of carbon sequestration in Mexican soils, for a good attention, management and dissemination of these ecosystems, without neglecting the importance it represents at local, regional and national levels before this environmental crisis and the eco-systemic services that wetlands provide, both social and environmental, since most of the studies on C sequestration and GHG emission have been conducted in temperate zones. In this review study, emphasis is placed on coastal, lacustrine or riparian wetlands, which are currently in a state of conservation risk due to various anthropogenic activities, for example, cattle ranching and agriculture (Marín-Muñiz, 2013).
