Stretching almost 1,900 miles from Colorado to the Gulf of Mexico, the Rio Grande/Río Bravo Basin (RGB) supplies drinking water for more than 6 million people and irrigation for about 2 million acres of land. The river also supports habitat for many at-risk and endangered species. Because of its size and diverse ecosystem services, the RGB faces complex shared-management challenges that will require coordination among many players. This project will provide opportunities for water managers and users across the basin to collaborate to prevent future conflicts and foster innovative water management in the face of a changing climate. The project leaders will design and convene one tribal RGB forum and will design...

The Gulf of Mexico coast of Louisiana and Texas faces threats from increasingly destructive extreme weather, heat, subsidence, and coastal erosion. Inland areas also face stronger storms, floods, and shifts in land development patterns. Increasing drought and extreme heat in Texas and New Mexico also exacerbate fires and floods. All of these regions are culturally rich, rapidly changing areas where people are working across political boundaries and organizations to protect and adapt people’s lifeways, sites and artifacts, and culturally important species, places and landscapes. This project will produce an action plan that describes ongoing efforts and identifies gaps in research and funding for cultural preservation...

The Rio Grande provides drinking water for more than six million people, irrigation water for two million acres of land in the United States and Mexico, and supports riparian ecosystems that are home to endangered species like the ocelot and Rio Grande silvery minnow. Climate variability and anthropogenic activities continue to stress this already limited water resource. This project was developed in response to a request from a group of stakeholders who work in the Basin and represent federal, state and local agencies, private industry, farmers, ranchers, and NGOs. These stakeholders identified the need for a comprehensive data resource that spatially depicts where conservation activities are occurring on the ground....

The South Central Climate Adaptation Science Center (CASC) has worked diligently to build new partnerships between scientists and resource managers to help address stakeholders’ science needs and questions through actionable science. However, the growth of the stakeholder base has led to an unmet demand for climate adaptation services. These services focus on sharing data, tools, research knowledge, and scientific guidance with communities and stakeholders. To meet this need, the South Central CASC will establish a new scientist position focused on climate adaptation services and research coordination to identify critically needed science solutions and to bridge the researcher and practitioner communities in the...

Science produced by the National and Regional Climate Adaptation Science Center (CASC) network must ideally be scientifically sound, relevant to a management decision, fair and respectful of stakeholders’ divergent values, and produced through a process of iterative collaboration between scientists and managers. However, research that aims to produce usable knowledge and collaborative approaches that boost usability are not common in academia or federal research programs. As a result, neither the process of creating such research nor the impacts to stakeholders are well understood or well documented. This lack of attention to the processes and impacts of collaborative scientist-stakeholder knowledge production also...

Stretching almost 1,900 miles from Colorado to the Gulf of Mexico, The Rio Grande supplies drinking water for more than 6 million people and irrigation for about 2 million acres of cropland. In addition to the ecosystem services it provides, the river supports habitat for many native species, such as trout, and the endangered silvery minnow and southwestern willow flycatcher. In 2010, a joint stakeholder committee, comprised of stakeholders in the South Central CASC and the USDA Southwest Climate Hub, focused on developing an improved understanding of changes in water availability and implications for natural resources and their management. Since then, the committee has identified the need for a forum to discuss...

Small creeks and streams often dry out during the summer but still support many insects, fish, crayfish, and plants. Though intermittent streams are the most common type of flowing water across the globe, not much is known about which, how, why, or when streams dry or about how patterns of drying affect species in these habitats. More information about patterns of stream drying can help inform the management of intermittent streams. This project will use sensors to track the presence and absence of water in streams across Oklahoma, Kansas, Texas, and New Mexico. This will allow for an estimate of different drying patterns, and what (for example, stream size, land use, rainfall, or soil type) influences each pattern....

Climate projections for the South-Central U.S. indicate increases of 2-5°F in average high temperatures by mid-century, declines of up to 4% in average precipitation, and increases in heatwaves and large rainfall events. This changing, more unpredictable climate makes it difficult to decide which species to plant when, or to know when certain species will bloom and go to seed. A refuge manager might ask: what species should be included in restoration plantings to ensure pollinators will have nectar ten years from now? Or a tribal member might wonder: when is the most effective time to visit prairie remnants to collect culturally significant plant seeds to grow for a restoration project? The Time to Restore project...

Increasing water usage and demands, combined with potentially less source water as a result of climate change impacts, are causing water resource managers to evaluate and implement alternative solutions for reducing water shortages, maximizing water availability, and reducing costs. The capture and reuse of wastewater is a promising strategy for increasing available water, but the costs and benefits of wastewater reuse are poorly quantified. In many locations, wastewater forms a significant component of stream flows for downstream beneficial uses. While wastewater reuse can boost local water availability, it also may reduce downstream flows and have negative impacts on downstream ecosystems. Therefore, assessing...

The greater Mississippi River Basin (MRB) is the largest river basin in North America and the fourth largest basin in the world. The MRB encompasses 24 terrestrial ecosystems, providing habitat for 100 species of mammals, reptiles, and amphibians Its floodplain supports 40% of the waterfowl and wading birds in North America, and the MRB’s rivers transport 40% of the nation’s total exports. Dozens of different cultures are scattered across the MRB with different policy structures, worldviews, and economic strengths. The heterogeneity in the environmental and socio-cultural settings across the MRB poses a challenge to climate adaptation and actionable resource management recommendations. Yet climate change has disrupted...

The Rio Grande is naturally a water-scarce basin in which droughts have been classified as severe (with almost no rain during some years) and extended (lasting more than 10, or even 15 years). Severe and persistent droughts in the Rio Grande basin reduce water availability, which triggers economic, environmental, and social impacts, and affects compliance with interstate compacts and international treaty commitments. In contrast, the Rio Grande basin is also affected by flood events that cause major losses to lives, properties, and economies. Understanding each of these periods of water scarcity and water abundance can help water managers to design adaptation strategies that cope with these two extremes while still...

Water availability in the upper Rio Grande Basin is dependent on winter and monsoon season precipitation. Consecutive years of drought and above average temperatures have diminished water supply and increased demand for water in this region. The increasing gap between water supply and demand is cause for concern. Climate projections for the southwestern and south central United States suggest that temperatures will continue to increase, affecting seasonal precipitation and water availability. To better manage current water supply and prepare for possible future changes, water managers need projections of future streamflow and landscape conditions that may affect future water supply. The project researchers are...

Ensuring the long-term sustainability of water resources requires careful stewardship of water for societal uses (i.e. municipal, agricultural, and industrial sectors) and also for the many other benefits that aquatic ecosystems provide to humans. In particular, reservoir fisheries and river ecosystems provide a range of economic, cultural, and recreational benefits. Maximizing the benefits that we receive from water will entail balancing societal uses, reservoir storage, and river flows. Climate change is expected to complicate the challenge of finding a balance among these three dimensions of water sustainability. To navigate these challenges, stakeholders need frameworks for simultaneously predicting the...

Ecosystems experience stress from a number of factors, but a changing climate exacerbates those stressors and alters ecosystem and soil productivity, leading to degradation of wildlife habitat and agricultural productivity. Response to these enhanced stressors requires that farmers, ranchers, and wildlife managers have the necessary information and resources to guide adaptive management decisions. Not only do they need better forecasts of drought severity, but also an understanding of the likely effects of drought on vegetation and soil at the decadal scale. To provide these resources, this project proposes to document and map climate change vulnerability of major grasslands and wetlands on the southern Great Plains...

Many inland bodies of water in western Louisiana are receiving too much sediment and nutrient pollution from upstream which has caused declines in the health of many fisheries. These bodies of water include many traditional lake-based fisheries of the Chitimacha Tribe of Louisiana (CTL), and fisheries used by visitors, providing critical tourism and economic development dollars to the region. The goal of the Coastal Indigenous Fisheries Assessment (CIFA) is to study the long-term health and ecology of fisheries and water bodies in west-central Louisiana. This project will be a collaboration between leaders and scientists from the Chitimacha Tribe of Louisiana, Louisiana State University and Florida State University...

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 different climate conditions than they have experienced in the past few centuries. As temperature and precipitation patterns change, “transformational drought”, or drought events that can permanently and irreversibly alter ecosystems – such as forests converting to grasslands – are a growing threat. This type of drought has cascading...

The south-central U.S. has a unique and complex topography that results in a strong precipitation gradient from the arid west to the humid east. Stakeholders and partners of the South Central CASC require climate projections about how these conditions may change to provide critical information for impact assessments and climate adaptation planning efforts related to their unique needs. For example, stakeholders and partners of the South Central CASC have identified a critical need for guidance about future water scarcity and wildfire frequency. While the South Central CASC has already produced climate projections for this region, a new generation of climate models that represent an updated scientific understanding...
