Building the Climate Change Resilience of Mongolia’s Blue Pearl A Case Study of Khuvsgul Lake National Park Climate change threatens to undermine the conservation values of protected areas, such as Khuvsgul Lake National Park (KLNP), one of Mongolia’s largest and most visited parks. Khuvsgul Lake is sacred to Mongolians and is known locally as the Blue Pearl. This publication presents the first quantitative assessment of the potential impacts of climate change to a protected area in Mongolia in relation to three dimensions: biodiversity, livelihoods, and tourism. Building resilience to climate change for the KLNP is critical and requires collaboration and coordination between national and international agencies, focused on addressing unsustainable livestock grazing and unmanaged tourism, improving habitat connectivity, and strengthening park management.

On the cover: Khuvsgul Lake National Park, one of Mongolia’s most visited protected areas, supports global biodiversity values, traditional grazing lands, and a rapidly growing tourism industry, centered around the country’s largest freshwater lake, Khuvsgul Lake. Overgrazing, unmanaged tourism, and climate change are threatening these values (photos by Mark R. Bezuijen and Michael Russell). Cover design by Jasper Lauzon.

Protected areas are fundamental in this regard: they are Splaces that help maintain healthy populations of plants and animals and protect the natural systems upon which life is based, including ecosystem services such as water supply and flood regulation. They provide a buffer from the risk of disease outbreaks and the impacts of climate change. Maintaining protected areas in good condition is critical to help protect nature and people, yet protected areas globally are under threat. Now, more than ever, as part of efforts toward a nature-based recovery from the COVID-19 crisis, there is a need to support the design, planning, and management of protected areas. Mongolia’s protected areas encompass deserts, grasslands, and snow-capped mountains—a stunning expanse of wilderness that supports globally important biodiversity values and nomadic patterns of life largely unchanged for thousands of years. Comprising a mosaic of parks and reserves, these areas support some of the largest and most intact natural systems remaining in the world, including pristine lakes and undammed rivers.
