Paper by Ryan Calder and Amina Schartup in AGU GeoHealth earns editor's highlight🏅 We describe how Earth and environmental research can produce policy benefits (rather than policy impact) via analysis of tradeoffs and anticipation of social responses to proposed interventions. 

Earth science investigations frequently conclude with policy advice that anticipates a straightforward impact on human health (black arrows). We call for analysis that considers the diverse mechanisms by which advice may pose health tradeoffs instead (white arrows). The conventional scientific workflow (top left) can also be enhanced by greater knowledge co-production and other strategies.

May 2023

Ryan Calder, Georgia Mavrommati (UMass Boston) and Richard Howarth (Dartmouth College) awarded $650,000 grant from the U.S. EPA to characterize environmental, economic, and health tradeoffs associated with alternative decarbonization pathways for New England. The project will couple engineering analysis with elicitation of values from community juries to screen alternative pathways in terms of compatibility with local values and priorities. The project will develop capacity for community-based environmental organizations to conduct independent analyses of proposed generation and transmission projects.

Integrated modeling of scenarios feeds into deliberative valuation workshops

May 2023

Ryan Calder writes letter to District of Columbia council, mayor, and agency directors urging action on traffic safety. The letter was co-signed by >650 individuals and nine local organizations urging action on traffic safety and has been covered in the national press.

Census Block Groups in the District of Columbia grouped by fraction of population Black or African American (alone or together with another race) in corresponding Census Tract plotted against number of crashes with fatal/serious injuries since 2016. Five top neighborhoods in ≥75% group are identified with Census Tract number in parentheses. Excluding Tract 98000 (population 18).

Paper by Ryan Calder and collaborators at Fisheries and Oceans Canada selected as editor's choice🏅 We argue that Atlantic herring decline is driven by natural predation exacberated by fishing and that the recent fisheries moratorium is justified by the precautionary principle.
