Summary/Abstract: In order to build the state of the art of the Economic Valuation of Flood Control Ecosystem Service of wetlands (VESECI, as per its acronym in Spanish), a systematic review of scientific information was carried out through which a bibliometric analysis was prepared, supported by bibliographic maps of networks and density processed in the VOSviewer® software. Likewise, the information of scientific articles was arranged in an Excel® database, which allowed us to identify the generalities of the valuation studies and obtain information on the economic value of flood control worldwide. The main findings indicate that the Asian continent leads research on the matter, with China being the country with the most research in this regard, and that the dominant subject area of research is Environmental Science with 37% of the studies found. The results showed that coastal wetlands, such as swamps, mangroves, and floodplains, are preferred in VESECI’s analyzes. It was found that the Environmental Economics approaches have been the most used in this kind of studies and that the value of wetlands varies according to the valuation method used, the scale of the study and the type of wetland studied. In general terms, it is concluded that the value of flood control ecosystem service (SECI) ranges between $ 238 USD/ha/year and $ 65 billion USD/year.
