The World’s Mangroves 2000–2020

Abstract

This report provides global and regional estimates of the area covered by mangrove forests, including area changes between 2000 and 2020. It analyses the drivers of these global, regional and subregional changes for the periods 2000–2010 and 2010–2020 with the aim of improving understanding of these drivers, their interactions and how their relative importance has shifted over time. In the study that underpins this report, FAO developed and validated an easy, repeatable methodology that integrates remote sensing with local knowledge. An FAO team and 48 image interpreters worldwide collected and analysed data on mangrove area in 2020, change in mangrove area between 2000 and 2020, and the drivers of change over the two decades. It is the first global study of mangrove area to provide information on land use rather than land cover.
