A need was identified to quantify the count and density of human populations living in mountainous areas in a transparent and reproducible fashion.

This project, which involved numerous partners, sought to address this information gap. 

The impacts of employing various alternative population datasets and mountain delineations on global and regional scale population estimates were explored. This effort should help to meet the information needs of global assessments, including those of the IPCC, as well as a host of other applications. In addition, associations between mountain population densities and several potential climatological, topographic, and other co-variates were explored, which may contribute to improved future projections of mountain populations under various broader demographic and climatic scenarios. 

An associated publication has been submitted to the journal PNAS (Thornton et al., under review). Furthermore, we have developed a "knowledge package" from the project which provides the full details necessary to reproduce the work (data, code, instructions, etc.). This resource will be made available via the GEO Knowledge Hub upon publication of the paper, and will enable the analysis to be repeated efficiently in future as new datasets become available.
