Where mangrove forests were lost worldwide (2000-2016)

Global Mangrove Loss Extent, Land Cover Change, and Loss Drivers, 2000-2016
biosphere NASA ORNL_CLOUD Level 4 multiple
In plain English

What it measures. Maps showing where the world's mangrove forests were lost between 2000 and 2016, broken into three periods, along with what drove each loss - whether farming, aquaculture, settlement, erosion, or extreme weather.

How it's made. Built from Landsat satellite imagery using a vegetation-greenness signal to detect loss, then a machine-learning (Random Forest) method combined with global land-use data to identify the cause of each loss.

How & where you'd use it. Useful for understanding mangrove decline across 39 nations and the human and climate pressures behind it, supporting coastal conservation and restoration.

Official description

This dataset provides estimates of the extent of mangrove loss, land cover change, and its anthropogenic or climatic drivers in three time periods: 2000-2005, 2005-2010, and 2010-2016. Landsat-based Normalized Difference Vegetation Index (NDVI) anomalies were used to determine loss extent in each period. The drivers of mangrove loss were determined by examining land cover changes using a random forest machine learning technique that considered change from mangrove to wet soil, dry soil, and water at each loss pixel. A series of decision trees used several global-scale land-use datasets to identify the ultimate driver of the mangrove loss. Loss drivers include commodity production (agriculture, aquaculture), settlement, erosion, extreme climatic events, and non-productive conversion. Maps of loss extent per period, mangrove land cover changes, and loss drivers are provided for each of 39 mangrove holding nations.
