There is increasing and broad recognition of the importance of Indigenous and local knowledge in leading climate change adaptation. Indigenous peoples and nations are on the front lines of climate change impacts, yet they are also leading the way in many innovative adaptation actions, such as traditional or cultural burning practices - a form of low-intensity understory-burning that...

Climate change adaptation research has made major advances over the last decade. For example, much is known about the impacts of climate change, many novel adaptation planning approaches have been developed, decision tools have become ubiquitous, and many novel adaptation options have been proposed. However, additional research is needed to demonstrate how these adaptation planning...

The fast pace of change in coastal zones, the trillions of dollars of investment in human communities in coastal areas, and the myriad of ecosystem services natural coastal environments provide makes managing climate-related risks along coasts a massive challenge for all of the U.S. coastal states and territories. Answering questions about both the costs and the benefits of alternative...

Climate change is altering the patterns and characteristics of fire across natural systems in the United States. Resource managers in the Southwest are faced with making natural resource and fire management decisions now, despite a lack of accessible information about how those decisions will play out as fire regimes, and their associated disturbances, will change across the landscape...

Abundant scientific research has characterized the relationships between climate and fire in ecosystems of the United States, and there is substantial evidence that the role of fire in ecosystems is likely to change with a changing climate. Changing fire patterns pose numerous natural resource management challenges and decision makers in natural-resource management increasingly require...

Drought and wildfire pose enormous threats to the integrity of natural resources that land managers are charged with protecting. Recent observations and modeling forecasts indicate that these stressors will likely produce catastrophic ecosystem transformations, or abrupt changes in the condition of plants, wildlife, and their habitats, in regions across the country in coming decades. In...

Healthy forests and woodlands in the western United States provide many important benefits, including providing habitat for wildlife, forage for livestock, and clean water for fish and human use. Yet climate change and other stressors, from wildfires and insect attacks to severe droughts, are causing unprecedented tree die offs across the region, threatening many of these ecosystem...

The impacts of climate change are widespread and accelerating. It is daunting for resource managers to determine how to use increasingly limited staff time and funding to conserve species and ecosystems. The Refugia Research Coalition is a national framework that brings together researchers and managers to identify and develop conservation strategies for “climate change refugia”, areas...

Healthy forests in the western United States provide multiple benefits to society, including harvestable timber, soil stabilization, and habitat for wildlife. On the Navajo Nation, over 5 million acres of forest provide wood that heats 50% of homes, building materials, summer forage for livestock, and drinking water. However, warming temperatures and changes in precipitation patterns can...

Drought events have cost the U.S. nearly $245 billion since 1980, with costs ranging from $2 to $44 billion in any given year. However, these socio-economic losses are not the only impacts of drought. Ecosystems, fish, wildlife, and plants also suffer, and these types of drought impacts are becoming more commonplace. Further, ecosystems that recover from drought are now doing so under...

The Colorado River and its major tributaries provide a crucial water supply for more than 40 million people in the American Southwest and in California. This water supply is primarily used in irrigated agriculture but also provides essential drinking water to many large metropolitan areas. Hydropower is also produced at many of the large dams on the river. River flows have declined...
