South Central

Oklahoma and Texas are facing significant future water shortages that threaten farming and ranching communities. Though conservation-based management practices are being implemented across the states, there are inadequate tools for monitoring vegetation water use efficiency in real time. Researchers supported by this South Central CASC project will develop a web-based tool using high...

Native American agroecosystems, crucial to cultural identity, face threats from an increasing frequency and duration of severe droughts, which affect ancestral crop production and seed sustainability. Researchers supported by this South Central CASC project will collaborate with Indigenous horticulturalists to design and test whether wastewater gardens can help sustain crop seed...

Wetlands along the Gulf Coast are crucial for reducing hurricane-induced flooding and as habitat for diverse wildlife, but are threatened by rising sea levels, climate change, and coastal development. Using remote sensing data, future climate data, and numerical models, researchers from this South Central CASC-supported project will collaborate with local expert groups to create data and...

Flooding in urban centers caused by increasingly severe storms has led to massive economic, social, and ecological damage. Researchers supported by this South Central CASC project will examine flood vulnerability and equity in mitigation efforts in Harris County, Texas, currently home to the highest concentration of federally funded relocation projects in the country. The resulting flood...

Climate change threatens many functions of wetlands and habitat connectivity for migratory shorebirds who use wetlands across the Southern Great Plains. Researchers supported by this South Central CASC project will survey stakeholders in the region, project climate impacts on wetland-dependent birds, and create tools for conservation planning (e.g., ranking wetland importance to...

Tallgrass prairies in the U.S. Southern Great Plains are threatened by the aggressive invasive plant Lespedeza cuneata, and climate change is expected to affect its spread in complex ways. Researchers supported by this South Central CASC project will use remote sensing, climate science, and ecological modelling to detect the plant, identify climate factors driving its spread, and...

The Bonnet Carré spillway (BCS) is a flood-control structure along the Lower Mississippi River designed to prevent flooding in the city of New Orleans by diverting excess water into the nearby Lake Pontchartrain estuary. Alarmingly, the BCS was opened as many times over the past decade (2011–2020) as it had been over the six prior decades combined (1951–2010), with devastating effects on...

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...

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...

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...

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...
