Description of Lecture

Has agricultural intensification been reducing or increasing total farmland in the US? A panel data was used to determine the association between agricultural intensification and cultivated area. Multivariate regression analysis suggested that the total amount of land in CRP is positively correlated with land-sparing, whereas crop prices and USDA farm subsidies have negative impacts. The increasing demand in biofuel production places the future agricultural systems under risk by encouraging the conversion of marginal land to production. Therefore, government policy should promote land-sparing effect under agricultural intensification. Agricultural subsidies should be restructured to minimize unintended environmental impacts.
