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

American Journal of Agricultural Economics, Volume 108, Issue 3, Page 829-855, May 2026.
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 ...

A Comparative Study on the Irrigation Suitability of Kerala's Rivers Using Fuzzy AHP and Conventional Methods

Irrigation and Drainage, Volume 75, Issue 2, Page 815-839, April 2026.
ABSTRACT Food security in Kerala depends on effective irrigation, but poor‐quality irrigation water poses threats such as salinity, sodicity and reduced soil productivity. Although past assessments have been localised, this study presents the first comprehensive, statewide evaluation of irrigation water suitability across 44 major rivers in Kerala.

Sensory Preference of Drinking Water Influenced by Subthreshold‐Level Mineral Salt Mixtures

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
A distinct preference plateau was identified, with liking maximized near the salts' absolute thresholds. Sweetness promotion and astringency suppression were the primary sensory mechanisms driving preference in these mineral salt mixtures. A predictive model pinpointed the optimal blend (0.92 mg/L KCl; 0.60 mg/L MgSO4), providing a practical, data ...
