The Rio Grande-Rio Bravo River is the second longest river in the US and is a critical drinking water source for more than 13 million people. It flows south from the snow-capped mountains of Colorado through the New Mexico desert, forms the border between Texas and Mexico, and empties into the Gulf of America at Brownsville, Texas. The multi-national, multi-state, ecologically diverse...

Tribal nations are one of the most vulnerable populations to climate change in the United States, because of their reliance upon the natural environment to sustain traditional ways of life and current lack of training and resources to respond to climate change impacts. This project sought to increase south-central U.S. tribes’ basic knowledge of climate science, connect them with tools...

Global climate models (GCMs) are a tool used to model historical climate and project future conditions. In order to apply these global-scale datasets to answer local- and regional-scale climate questions, GCMs undergo a process known as “downscaling”. Since there are many different approaches to downscaling there associated sources of uncertainty; however, downscaled data can be highly...

Fire is a natural and necessary component of the South Central Plains ecosystem. However, fire suppression and more frequent droughts in the region have resulted in a build-up of dry fuels loads such as dead wood, resulting in fires that burn hotter and impact the landscape more severely. Uncontrolled wildfires have cost the region several billion dollars over the past five years...

Across the Southern Great Plains, increasing temperatures are expected to alter the hydrological functioning of the region by contributing to severe droughts, more intense rainfall events, and more severe flooding episodes. These changes could adversely affect human and ecological communities. The ability to better predict future changes in precipitation and the response of hydrologic...

Understanding how to manage scarce water during drought is one of the great challenges we face as a society, particularly for communities in the Rio Grande Basin. Severe drought coupled with human development have profoundly impacted the quantity and quality of water in the basin. Running through Colorado, New Mexico, Texas, and Mexico, the Rio Grande is a multi-national resource that is...

Most resource managers need to take climate impacts into account when making decisions during the course of their career, whether their work protects native species populations, reduces the impact of extreme storms on infrastructure, or improves water quality in a watershed. Professional training that develops an understanding of the climate system, how it is changing, and what that...

The South Central U.S. is home to diverse climates and ecosystems, strong agricultural and energy sectors, and fast-growing urban areas. All share a critical need for water, which is becoming an increasingly scarce resource across the region as aquifers are overdrawn and populations grow. Understanding what brings rain to this region, and how the timing and amount of precipitation may be...

Investigating the complex natural and cultural resource management challenges we face today requires building diverse, interdisciplinary research teams. Robust stakeholder engagement is also critical for ensuring that publicly funded science answers questions that are relevant to natural and cultural resource management decisions. Early career scientists who learn how to engage with...

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...

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...
