SDG Indicator 15.4.2 - Mountain Green Cover

Indicator 15.4.2 - Mountain Green Cover Index

The Mountain Green Cover Index (MGCI) measures changes in the area of green vegetation in mountain areas (forest, shrubs and pasture land, and cropland). This information will help identify the status of conservation of mountain environments in order to measure progress towards SDG Target 15.4.

By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development.

Impact

This indicator ensures that mountains are efficiently managed, and a better balance is struck between conservation and sustainable use of natural resources.

Key results

As of 2017, 76 percent of the world’s mountain areas were covered by a form of green vegetation, including forests, shrubs, grassland and cropland. Across regions, mountain green cover was lowest in Western Asia and Northern Africa (60 percent) and highest in Oceania (96 percent). In most cases, the green coverage of mountain areas is positively correlated to their state of health and to their capacity to fulfil their ecosystem roles.

As of 2017,  baseline data for the Mountain Green Cover Index has been developed. Disaggregated information by elevation class (UNEP-WCMC mountain classification by Kapos et al.) and for each IPCC land cover class (forests, cropland, grassland, wetlands, settlements, other land) has also been estimated. The Mountain Green Cover Index is an effective tool to show how mountain ecosystems evolve and to assess their state of  conservation and health.
