- 요약Food systems play an essential role in feeding humanity. Despite improvements over the last century, food systems still have negative impacts on humans, animals, and the environment. As a result, food systems require substantial transformations to meet sustainability goals. While some win-win opportunities may exist to improve multiple objectives simultaneously through food systems transformations, the consequences of large-scale shifts towards sustainability often involve tradeoffs that, while ranging in severity, are important to understand for decision making. This dissertation includes three separate studies evaluating tradeoffs and constraints in food systems transformations. In Chapter 2, I used a simple microeconomic model to characterize rebound effects from reducing food loss and waste (FLW). I found that rebound effects could offset more than 50% of avoided FLW. Such rebounds would imply similar percentage reductions in environmental benefits and improvements in food security benefits, highlighting a tradeoff between these two objectives as a result of reducing FLW. In Chapter 3, I used a novel dataset on regulations to determine differences in the way food industries are regulated in the United States (U.S.). I found that aquaculture is subject to anywhere from 3-72 times more regulations than other food sectors in the U.S.. Food industries with low-environmental impacts, like those in aquaculture (e.g. seaweed farming) are also subject to equal or greater numbers of regulations than food industries with high-environmental impacts (e.g. beef and lamb). Thus, the U.S. regulatory landscape may disadvantage low-impact food industries, especially aquaculture, in the marketplace. In Chapter 4, I combined environmental and animal welfare impact data to assess tradeoffs in Canadian egg production. I found that cumulative pain for laying hens could be reduced by nearly 60% per kilogram of eggs produced, while increasing environmental impacts by less than 5%. This analysis contributes a novel approach to a small, but growing literature quantifying and comparing animal welfare to other food systems objectives and reveals an opportunity for a big-win-small-loss tradeoff. Collectively, these three studies highlight the importance of quantifying understudied and unanticipated tradeoffs and constraints in sustainability transformations. My results may be useful to a variety of stakeholders, ranging from farmers to policy makers, interested in simultaneously balancing multiple objectives as they seek to transform the food system.
