Changes in NDVI and population in protected areas on the Tibetan plateau.
Understanding the Tibetan Plateau’s role in environmental change has gained increasing scientific attention in light of warming and changes in landmanagement. We examine changes in greenness over the Tibetan Plateau using the Normalized Difference Vegetation Index (NDVI) from the Global Inventory Mo...

We examine changes in greenness over the Tibetan Plateau using the Normalized Difference Vegetation Index (NDVI) from the Global Inventory Monitoring and Modeling Study (GIMMS3g) to identify significant changes over the entire plateau, six ecoregions, and protected areas based on a multiyear time series of July imagery from 1982 to 2015.

Understanding the Tibetan Plateau’s role in environmental change has gained increasing scientific attention in light of warming and changes in landmanagement. We examine changes in greenness over the Tibetan Plateau using the Normalized Difference Vegetation Index (NDVI) from the Global Inventory Monitoring and Modeling Study (GIMMS3g) to identify significant changes over the entire plateau, six ecoregions, and protected areas based on a multiyear time series of July imagery from 1982 to 2015.
