Agricultural large-scale land acquisitions have been linked with enhanced deforestation and land use change. Yet the extent to which transnational agricultural large-scale land acquisitions (TALSLAs) contribute to-or merely correlate with-deforestation, and the expected biodiversity impacts of the intended land use changes across ecosystems, remain...

The adoption of sustainable agriculture practices is critical for future ecological, food security, and farmer livelihood goals. Traditionally, the adoption of sustainable agriculture practices is treated as a binary decision, which simplifies the known complexity around behavior change. We propose a framework for the adoption of sustainable agricu...

Diverting food waste from landfills to composting or anaerobic digestion can reduce greenhouse gas emissions, enable the recovery of energy in usable forms, and create nutrient-rich soil amendments. However, many food waste streams are mixed with plastic packaging, raising concerns that food waste-derived composts and digestates may inadvertently i...

In many rural farming societies, wild plant foods (WPFs) continue to play an important role in everyday diets as well as in coping with hunger during food shortages. However, WPF collection and consumption may pose challenges to biodiversity conservation efforts (e.g., in protected areas), and some “famine foods,” foods not typically eaten under no...

Calcium is a nutrient of public health concern and commonly associated with dairy foods. In recent years, plant-based alternatives to dairy products have grown in popularity. This study examines public understanding of dietary calcium in dairy products and plant-based alternatives and explores whether knowledge is associated with product preference...

Puerto Rico has experienced a decline in the number of farms since the 1990s which parallels trends in the broader Caribbean. The islands share characteristics that contribute to their frail food security, including limited land masses, small economies, isolation, and embeddedness in neocolonial dynamics. The aftermath of the 2017 category 4 Hurric...

Background Federal nutrition assistance programs serve as safety nets for many American households, and participation has been linked to increased food security and, in some instances, improved diet quality and mental health outcomes. The COVID-19 pandemic brought new and increased economic, social, and psychological challenges, necessitating inqui...

Among one of the key challenges in dairy production is the management of manure in a way that is beneficial for agricultural production, with minimal environmental and public health impacts. Manure management systems (MMS)—the entire system of handling, storage, and application of manure—are diverse in countries with developed dairy industries such...

We examine the relationship of home food procurement (HFP) during COVID-19 to emotional eating and stress using a statewide representative survey (n = 600) in Vermont. Women and people with a job change since COVID-19 were more likely to experience higher stress and emotional eating. Engaging in HFP, especially gardening, is associated with less em...

Review, promotion, and tenure (RPT) processes at universities typically assess candidates along three dimensions: research, teaching, and service. In recent years, some have argued for the inclusion of a controversial fourth criterion: collegiality. While collegiality plays a role in the morale and effectiveness of academic departments, it is amorp...

Islands are uniquely vulnerable to extreme weather events and food insecurities, and have additional response challenges due to their limited territories and economies, isolation, colonial legacies, and high dependence of food imports. Domestic farmers have a key role in producing food for island communities like Puerto Rico, which can safeguard fo...
