Wetland Extent Trends Index [BIP]
Indicator description
The Wetland Extent Trends Index measures trends in wetland area over time, enabling the rate of loss (or growth) of wetland areas to be estimated and gives an indication of the status of wetlands globally. The analysis is based on a database containing over 1,000 wetland extent time-series’ and a methodology was developed to identify and account for thematic and geographic gaps, and conversely, over-representation in the data.
