Lost ground, lost value: Investigating the relationship between soil erosion and agricultural land value

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

open access: yesAngewandte Chemie, EarlyView.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.

Introducing farmer group learning and development into organic small holder farming systems in the global south -including a case study from the state of Madhya Pradesh, India.

open access: yes, 2012
On most continents food production has surpassed the growth in population (Knudsen et al. 2006). Still it is estimated that approximately 1 billion people are undernourished (FAO 2011) and the greatest number of people suffering from chronic hunger are ...

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Sustainability of Corn Stover Harvest for Biomass

open access: yes
Off-farm demand for crop residues is expected to grow as bioenergy policies become effective. Demand for residues will provide farmers with an additional source of revenue but it may also trigger losses in soil organic carbon and increases in fertilizer ...

Zebrafish and CRISPR—A synergistic approach to decipher and cure human diseases

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Zebrafish, with high genetic homology to humans, serves as a powerful vertebrate model for disease modeling and drug discovery. Integration of CRISPR/Cas9 technology enables precise genome editing, facilitating the development of translational models for human diseases.
