University of Delaware’s Rodrigo Vargas is among a group of leading forest scientists around the U.S. arguing in a new review that forest carbon market protocols are flawed and don’t ensure that issued carbon credits accurately account for reduced and removed CO2 emissions. The researchers say improvements could boost forest carbon credits’ quality and drive up demand as well as confidence in the market.

Efficient water usage in agriculture is crucial for sustaining a growing human population. Analyzing 21st century global crop dynamics, UD faculty member Kyle Davis and doctoral student Endalkachew Kebede co-authored new research that includes a comprehensive data library of crop-specific irrigated and rainfed harvested areas for all countries.

Angelia Seyfferth discusses her innovative study of arsenic uptake in rice, the trouble of salt water intrusion, and growing rice where it isn’t typically found. The Plant and Soil Sciences faculty member addresses the challenges and rewards of academia, mentorship, gender representation in STEM, and much more.

Elizabeth Smith, a former NSF Graduate Research Fellow and UD Plant and Soil Sciences Ph.D. alumna, investigated soil respiration using machine learning to better understand its role in the global carbon cycle. Analyzing two decades of data from multiple datasets, her research revealed unexpected patterns in national and global soil respiration trends. Now a postdoctoral researcher at Georgia Tech, Smith is expanding her computational expertise to study enhanced rock weathering, a technique for carbon capture in agriculture. Passionate about science communication, she also works to make environmental research more accessible, bridging the gap between scientific discovery and public understanding.
