Grasslands and forage crops (e.g., alfalfa and wheat) provide essential feed for livestock production. Grassland and forage production are often challenged by extreme climate (e.g., drought) and land management practices (e.g., burning, grazing, and harvesting). Sustainable management of grasslands and forage crops requires systematic monitoring of biophysical factors. Data from multiple sources such as field surveys, controlled experiments, eddy covariance observations, remote sensing (e.g., satellites and unmanned aerial systems (UAS)), and their subsequent integration into models is required to better understand the impacts of climate variability and land management practices. We seek contributions on evaluating the impacts of climate and/or different land management practices on grassland, forage productivity, species composition, and carbon-water relations; and large-scale analysis of grassland, and forage conditions (e.g., loss or degradation of grasslands). Both field and modeling studies or model-data integration are welcome.
