This report shines a light on the state of freshwater ecosystems today. Through EO data we can observe when and where ecosystems are degraded and although no comprehensive suite of data exist for each and every ecosystem the world over, the proxy information available from satellite imagery, does provide a strong evidence base for freshwater ecosystem changes, and the data through which to sound an alarm on the extent degradation is occurring. The report highlights trends, both positive and negative, occurring to surface water, river flow, lake pollution and mangroves.
