Conservative agricultural management strategies pursue long-term ecological benefits through practices such as no-tillage, cover crop, and inherent soil properties management. Farmers, however, are often hesitant to adopt such practices due to lack of experience, initial expense, and concern for low crop productivity. Overcoming this barrier requires novel approaches, such as effectively managing the soil microbiome to attain high productivity at a low cost, especially in a semi-arid region. To study the potential of conservation agriculture, we investigated components of soil bacterial community and rhizobial diversity in long-term experimental cotton fields divided into conventional tillage monoculture systems...

Chelenzo Farms, located twenty miles south of the city of Santa Fe, New Mexico, is a regenerative farm that applies permaculture, soil health, and agroecology principles. It has three operating principles of research, education, and community. It practices dryland farming, focusing on the cultivation of agave and native plants. With over 200 varieties, agave can be distilled to make liquor, fermented for livestock feed, and made into textiles. In fact, 75% of those varieties have been cultivated in Mexico for thousands of years. Thus, agaves have long supported a variety of pollinators in the Southwest and along the border with Mexico in the Chihuahuan and Sonoran deserts, with the best known one being the...

This dataset contains the input files, script, and output files regarding 110 years of daily regulated (observed) and naturalized streamflow (million cubic meters/day) for ten gauge stations in the Rio Grande/Bravo basin. The gauge stations included are at Amistad, Anzalduas, Artesia, Below Presidio, Laredo, Conchos Outlet, Foster Ranch, Laredo, Pecos Outlet, Salado River, and San Juan River.
Wetland ecosystems are vital for maintaining global biodiversity, as they provide important stopover sites for many species of migrating wetland-associated birds. However, because weather determines their hydrologic cycles, wetlands are highly vulnerable to effects of climate change. Although changes in temperature and precipitation resulting from climate change are expected to reduce inundation of wetlands, few efforts have been made to quantify how these changes will influence the availability of stopover sites for migratory wetland birds. Additionally, few studies have evaluated how climate change will influence interannual variability or the frequency of extremes in wetland availability. For spring and fall...

Scientists, planners, policy makers and other decision-makers in the South Central U.S. want to understand the potential impacts of changes in climate, precipitation, and land-use patterns on natural and cultural resources. Though the potential impacts of climate change can be modeled to help decision-makers plan for future conditions, these models rarely incorporate changes in land-use that may occur. Climate change and land-use change are often linked, as shifts in precipitation and temperature can alter patterns in human land-use activities, such as agriculture. This project sought to address this gap by developing new software tools that enable stakeholders to quickly develop custom, climate-sensitive land-use...

Pollinator restoration requires information about what species to plant and when to plant them to ensure food sources are available throughout the periods when pollinators are active. Changes in climate, including earlier spring warming and warmer fall temperatures, may cause flowering to become out of sync with pollinator activity. When restoring land to support pollinators, managers are challenged to select a mix of species that support pollinators of concern throughout their periods of activity. Existing planting tools have several disadvantages such as, their usability is location specific, they are virtually non-existent for the South Central region, and they do not often account for future changes in plant...

In the Western U.S., approximately 65% of the water supply comes from forested regions with most of the water that feeds local rivers coming from snowmelt that originates in mountain forests. The Rio Grande headwaters (I.e. the primary water generating region of the Rio Grande river) is experiencing large changes to the landscape primarily from forest fires and bark beetle infestations. Already, 85% of the coniferous forests in this region have been affected by the bark beetle, and projections indicate greater changes will occur as temperatures increase. In this area, most of the precipitation falls as snow in the winter, reaches a maximum depth in the late spring, and melts away due to warmer temperatures by early...

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding, erosion, and water quality issues. These events can be costly for society. In response, many land managers are using forest thinning and prescribed burning practices to reduce disturbance impacts, especially those that are caused by high-severity wildfire. In contrast to the wealth of research on the advantages of forest thinning...

The South Central Climate Adaptation Science Center (CASC) has several Communities of Practice (CoPs) focused on resource manager needs across the region (e.g. understanding at-risk species and ecosystems, building resilient coastal ecosystems, extreme weather and climate change, etc.). Each CoP has expertise in the subject matter and has been working on projects that are relevant to the resource community, including conducting literature reviews and small-scale pilot projects. The current research project will leverage the expertise of the existing CoPs to enhance the content available through the Conservation and Adaptation Resources Toolbox (CART) as identified through the partnership between the South Central...

Drought is a common consequence of climate variability in the south-central U.S., but they are expected to occur more often and become more intense with climate change. Natural resource managers can improve their planning efforts with advance warnings of impending drought. Using input from resource managers in the Chickasaw Nation, this research team previously created models that forecast droughts up to 18 months in advance with information about their expected timing and intensity. Developed for all climate divisions in Louisiana, New Mexico, Oklahoma, and Texas, these drought models rely on input from predictor variables associated with global weather patterns like El Niño and La Niña. However, it is unclear...

A limited amount of valid scientific information about global climate change and its detrimental impacts has reached the public and exerted a positive impact on the public policy process or future planning for adaptation and mitigation. This project was designed to address this limitation by bringing together expertise in the social and communication sciences from targeted academic institutions affiliated with the Department of the Interior’s Climate Science Centers (CSCs) through a workshop. The project team brought together expertise in the social and communication sciences from targeted academic institutions, particularly experts and scholars who are affiliated with the nation’s CSCs, by means of an invited...

The U.S. Great Plains is known for frequent hazardous convective weather and climate extremes. Across this region, climate change is expected to cause more severe droughts, more intense heavy rainfall events, and subsequently more flooding episodes. These potential changes in climate will adversely affect habitats, ecosystems, and landscapes as well as the fish and wildlife they support. Better understanding and simulation of regional precipitation can help natural resource managers mitigate and adapt to these adverse impacts. In this project, we aim to achieve a better precipitation downscaling in the Great Plains with the Weather Research and Forecast (WRF) model and use the high quality dynamic downscaling results...
