Mountains play an essential role in supplying water and other services, such as food, energy and biodiversity, to the millions of people living in the mountains and downstream. This map shows where mountains are located around the world and the human population densities within these regions. Short case studies, which are referred to in the accompanying Waste Management Outlook for Mountain Regions - Sources and Solutions, highlight the variety of waste challenges and opportunities in mountain regions.
