The Water Adaptation Techniques Atlas (WATA) catalogs information about responses to water scarcity in the southwestern U.S., presented in the form of case studies.
The USDA SWCH is part of a five-year integrated project to develop improved educational materials, modes of communication and issue expertise that will help in assisting farmers and ranchers to better assess the sources of past crop and livestock production losses due to weather and climate disruption as well as explore future trends in these causes of loss. In so doing we advance adaptation to extreme weather variability and climate change. It is essential to understand past trends and likely future sources of weather and climate risks before making changes in production systems.

Drivers of Soil Carbon and Nitrogen Cycling in Semi-arid Agroecosystems

This research monitors soil organic carbon (SOC) and nitrogen (N) fractions and dynamics under diverse cropping systems as an index of agroecosystem resilience in the semi-arid southwest to:
• Quantify SOC and N fractions under diverse cropping practices.
• Study the long-term SOC dynamics by using a DAYCENT Ecosystem model.
