Size‐based regulation and water quality: Evidence from the Iowa hog industry

American Journal of Agricultural Economics, EarlyView.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

Deadly Lifeworlds Meet Palliative Politics: Struggle in Circulation

Antipode, EarlyView.
Abstract This paper locates acute and ongoing crises of coloniality and ecology within struggles over circulation that are anchored in infrastructure. If infrastructure organises movement—including its constraint in carceral forms—then it is also a linchpin for materialising distinct regimes of motion (Nail 2020a; Marx in Motion: A New Materialist ...

Colonizing Canis lupus: Wolf Management as a Settler Colonial Project

Rural Sociology, Volume 90, Issue 3, September 2025.
ABSTRACT The hostility to wolves by segments of agribusiness and the general public in the United States is a puzzle, given that wolf predation is not responsible for a large number of cattle and sheep losses and has only a very modest economic effect on the livestock industry.

Carbon and Nitrogen Isotope Composition of Australasian Hair and Fingernails in a Global Context

Rapid Communications in Mass Spectrometry, Volume 39, Issue 15, 15 August 2025.
ABSTRACT Rationale The stable carbon (δ13C) and nitrogen (δ15N) isotope composition of human bone and tissues encodes dietary information that in some circumstances can be attributed to geographical location. While there is a global dataset amounting to > 4000 samples, limited data are available for the Australasian region.

Impacts of Interannual Isoprene Variations on Methane Lifetimes and Trends

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Recent observations show anomalously high methane growth in 2020, which has been attributed to increased wetland emissions and decreased OH from lower COVID‐19 nitrogen oxide (NOx) emissions. NOx is not the only species that affects OH—isoprene, the most significant non‐methane hydrocarbon by total emissions, is oxidized by OH, which can ...

US employment exposure to domestic and foreign tariff changes under NAFTA

Applied Economic Perspectives and Policy, Volume 47, Issue 3, Page 1058-1094, July 2025.
Abstract Literature examining the effects of changes in trade agreements and import competition on US employment and wages has focused primarily on non‐agricultural industries and changes in US import tariffs. We propose a method for measuring worker exposure to changes in agricultural tariffs using a newly developed county‐level dataset of employment ...
