Progress on Water-Related Ecosystems

Protecting and restoring water-related ecosystems will mitigate and strengthen resilience to climate change. For instance, wetlands trap carbon from the atmosphere and protect coastal areas from storm surges and inland areas from both floods and droughts by retaining water.

  • 4.37 % of the world’s water basins is experiencing rapid changes in the area covered by permanent surface waters (SDG 6 indicator 6.6.1, 2022)

Available time series: 2000-2022
Number of countries (and areas) reporting in the last five years: 231
Proportion of world population covered by reporting in the last five years:98%

Proportion of world land area covered by reporting in the last five years: 99%

SDG target 6.6 is: ‘By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes.’

To track progress towards the target, indicator 6.6.1 tracks changes over time in water-related ecosystems such as lakes, rivers, wetlands and mangroves, with the help of earth observations.
