This $185,453 federal Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports collaborative research to quantify shifts in maize production in North America over the past 1,200 years. The research leverages paleoclimate data, weather modeling, and crop simulation techniques to understand the impacts of historical megadroughts and climate change on food production. Key activities include developing open-source software for climate field...
This $198,435 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project titled "P4CLIMATE--A Paleo Perspective on the Links Between Climate and Food Security." The project will quantitatively assess shifts in maize production in North America over the past 1,200 years by merging paleoclimate, weather generation, and crop modeling data. This research aims to understand the impacts of prolonged droughts,...
This National Science Foundation (NSF) Geosciences program (CFDA 47.050) Project Grant award of $399,984 to the University of Wisconsin-River Falls (UW-River Falls) seeks to study the cycling and transport of carbon (C) and nitrogen (N) in agricultural soils. The two-year project, titled "EMBRACE-EAR-GROWTH: Coupling In-Situ Probing and Modeling Moisture-Related Soil Carbon and Nitrogen Cycling and Transport", aims to: Decipher redox-related soil C and N cycling, mobilization,...
This National Science Foundation Project Grant of $184,289 supports research at Texas A&M Agrilife Research to advance understanding of how iron impacts the temperature sensitivity of heterotrophic respiration in humid tropical soils. The award period is from May 1, 2023 through April 30, 2026. The research leverages experiments and process-based modeling at the Tropical Responses to Altered Climate Experiment in Puerto Rico's Luquillo Rainforest. Comprehensive experiments with soils sampled...
This Project Grant award from the National Science Foundation's (NSF) Social, Behavioral, and Economic Sciences (CFDA 47.075) program provides $121,978 to the University of Georgia Research Foundation, Inc. to investigate the long-term relationship between climate change and agricultural response, focusing on human interactions with plants and animals in dynamic natural and cultural landscapes. The research aims to illuminate how agrarian societies have responded to pronounced environmental...
This Project Grant from the National Science Foundation Division of Earth Sciences provides $174,000 to study the connections between silicate weathering and organic carbon cycling in watersheds within the Upper Deschutes Basin in Oregon from September 2021 through August 2023. The grant supports basic research under the Geosciences program (CFDA 47.050), which aims to strengthen understanding of the integrated Earth system through atmospheric, earth, and ocean sciences. Specifically, the...
This $205,186 Project Grant awarded by the National Science Foundation's Geosciences program (CFDA 47.050) to Texas A&M AgriLife Research will support research to improve the measurement and prediction of crack formation in shrink-swell soils. The overarching goal is to enhance models of water flow and contaminant transport in these dynamic soil systems, which have a disproportionately large impact on water quantity and quality. Key objectives include: 1) quantifying the relationship between...
This $398,984 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to quantify the biophysical, physiological, and phenological impacts of increasing carbon dioxide (CO2) levels on vegetation and their effects on future climate change. The research utilizes the Community Earth System Model to examine the direct impacts of CO2 fertilization and stomatal closure, as well as the indirect effects of a longer growing season, on...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will support research by Texas Tech University to investigate the predictability of severe weather events, such as tornadoes, hail, and flooding, under current and future climate conditions. The $380,904 award, effective from September 1, 2023 to August 31, 2026, will involve creating and analyzing large datasets of numerical weather model forecasts to understand how and why the predictability of...
This Project Grant award, funded by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to advance the understanding of extreme precipitation events and their impacts. The award of $870,213, effective from September 1, 2025 to August 31, 2030, will address three key questions: 1) how precipitation distribution depends on spatial and temporal scales, 2) the comparative roles of aerosol and greenhouse gas forcing in precipitation distribution, and 3) the impact...
