Drought, Fire and Extreme Weather

 

Droughts, fires, and extreme weather events like hurricanes have become more common and more devastating in recent years. CASC-supported scientists are working to understand how these phenomenon are affecting important natural and cultural resources and how they will continue to change over time.

Soil Moisture-Based Drought Monitoring for the South Central Region

Soil moisture is a critical variable for understanding the impacts of drought on ecological, hydrological, and agricultural systems. Yet, key research gaps currently prevent existing soil moisture measurements from being used to assess drought conditions and mitigate drought impacts such as wildfire outbreaks, lost agricultural production, and degraded wildlife habitat. In fact, most scales used t

The Impact of Drought on Waterbirds and Their Wetland Habitats in California’s Central Valley

California’s Central Valley is a nexus for water resources in the state, draining the Sacramento and San Joaquin River watersheds. Urban centers, agricultural operations, and the environment all compete for limited water, and demand is expected to only increase as the population grows and agriculture intensifies. At the same time, the water supply is projected to decrease as temperatures rise, pre

The Wind River Indian Reservation’s Vulnerability to the Impacts of Drought and the Development of Decision Tools to Support Drought Preparedness

The Wind River Indian Reservation in west-central Wyoming is home to the Eastern Shoshone and Northern Arapaho tribes, who reside near and depend on water from the streams that feed into the Wind River. In recent years, however, the region has experienced frequent severe droughts, which have impacted tribal livelihoods and cultural activities. Scientists with the North Central Climate Science Ce

Understanding the Ecological Impacts of Drought Across the U.S.: Regional Workshops and National Synthesis

Climate change is expected to increase the intensity and frequency of drought in the U.S., leading to potentially harmful ecological impacts. The uncertain and relatively rapid changes to precipitation patterns pose a significant challenge to managers and decision-makers. In addition to having negative social and economic implications, long periods without rainfall can alter ecosystems, thereby th

Community Resilience to Drought Hazard: An Analysis of Drought Exposure, Impacts, and Adaptation in the South Central U.S.

The threat of droughts and their associated impacts on the landscape and human communities has long been recognized in the United States, especially in high risk areas such as the South Central region. There is ample literature on the effects of long-term climate change and short-term climate variability on the occurrence of droughts. However, it is unclear whether this information meets the needs

Developing Effective Drought Monitoring Tools for Farmers and Ranchers in the South Central U.S.

The South Central U.S. is one of the main agricultural regions in North America: annual agricultural production is valued at more than $44 billion dollars. However, as climate conditions change, the region is experiencing more frequent and severe droughts, with significant impacts on agriculture and broader consequences for land management. For example, in 2011 drought caused an estimated $7.6 bil

Disappearing Refugia: Identifying Trends and Resilience in Unburned Islands under Climate Change

Wildfires are one of the greatest threats to human infrastructure and the ecosystem services humans value in the western US, but are also necessary in fire-adapted ecosystems. Wildfire activity is widely projected to increase in response to climate change in the Northwest, but we currently lack a comprehensive understanding of what this increase will look like or what its impacts will be on a vari

Effects of Sea-Level Rise and Extreme Storms on California Coastal Habitats: Part 2

In California, the near-shore area where the ocean meets the land is a highly productive yet sensitive region that supports a wealth of wildlife, including several native bird species. These saltmarshes, mudflats, and shallow bays are not only critical for wildlife, but they also provide economic and recreational benefits to local communities. Today, sea-level rise, more frequent and stronger stor

Examining the Influence of Temperature and Precipitation on Colorado River Water Resources: Reconstructing the Past to Understand the Future

Streamflow in the Colorado River is heavily influenced by high-elevation snowpack. Warming temperatures in spring can reduce snow-fed flows, with serious implications for the water supplies that support communities and wildlife. While it is already well-known that precipitation has a significant influence on river flow, recent observations suggest that temperature and the amount of water in soil m

Foundational Science Area: Developing Climate Change Understanding and Resources for Adaptation in the North Central U.S.

In the North Central U.S., drought is a dominant driver of ecological, economic, and social stress. Drought conditions have occurred in the region due to lower precipitation, extended periods of high temperatures and evaporative demand, or a combination of these factors. This project aimed to improve our understanding of drought in the North Central region and determine what future droughts might

The north-central region of the U.S. has experienced a series of extreme droughts in recent years, with impacts felt across a range of sectors. For example, the impacts of a 2002 drought are estimated to have resulted in a $3 billion loss to the agricultural sector in Nebraska and South Dakota.

How Does Drought Influence Fire Severity in the Southwestern U.S.?

There is a growing realization that current warming trends may be associated with increases in the size, frequency, and severity of forest fires in the West. While rising temperatures can create drought conditions that favor severe fires, it is also possible that drought limits the ability of trees to survive a fire. During a drought, there is less water available for trees and more outbreaks of h
