Teachers and School Health Leaders' Perspectives on Distance Learning Physical Education During the COVID-19 Pandemic.

BACKGROUND: Due to the COVID-19 pandemic, students and teachers have transitioned to online learning. The transition required changes in teaching practices to accommodate for an online learning environment. However, there are no studies characterizing physical educators' and school health experts' perspectives on physical education via distance learning or identifying best practices and their implications for student health. METHODS: Using purposive and snowball sampling, we conducted semi-structured interviews with 19 physical education teachers and school health experts across 21 California school districts on best practices for physical education via distance learning. Interviews were recorded, transcribed, and analyzed using a grounded theory approach. RESULTS: Four major themes emerged: (1) participants felt high quality physical education via distance learning was both critical and possible; (2) strategies for creating a successful distance learning environment included personalization, creativity, and inclusiveness; (3) resources necessary for success included professional development, administrative support, and equipment; and (4) lessons for the long-term. CONCLUSIONS: Participants identified effective strategies, challenges, and recommendations for the future. Participants felt optimistic about their ability to provide quality physical education via distance learning, given the necessary supports, and perceived that they played a critical role in supporting student health during the COVID-19 pandemic.

Supply chains for processed potato and tomato products in the United States will have enhanced resilience with planting adaptation strategies.

Food systems are increasingly challenged to meet growing demand for specialty crops due to the effects of climate change and increased competition for resources. Here, we apply an integrated methodology that includes climate, crop, economic and life cycle assessment models to US potato and tomato supply chains. We find that supply chains for two popular processed products in the United States, French fries and pasta sauce, will be remarkably resilient, through planting adaptation strategies that avoid higher temperatures. Land and water footprints will decline over time due to higher yields, and greenhouse gas emissions can be mitigated by waste reduction and process modification. Our integrated methodology can be applied to other crops, health-based consumer scenarios (fresh versus processed) and geographies, thereby informing decision-making throughout supply chains. Employing such methods will be essential as food systems are forced to adapt and transform to become carbon neutral due to the imperatives of climate change.

Protocol for life cycle assessment modeling of US fruit and vegetable supply chains- cases of processed potato and tomato products.

This article elaborates on the life cycle assessment (LCA) protocol designed for formulating the life cycle inventories (LCIs) of fruit and vegetable (F&V) supply chains. As a set of case studies, it presents the LCI data of the processed vegetable products, (a) potato: chips, frozen-fries, and dehydrated flakes, and (b) tomato-pasta sauce. The data can support to undertake life cycle impact assessment (LCIA) of food commodities in a "cradle to grave" approach. An integrated F&V supply chain LCA model is constructed, which combined three components of the supply chain: farming system, post-harvest system (processing until the consumption) and bio-waste handling system. We have used numbers of crop models to calculate the crop yields, crop nutrient uptake, and irrigation water requirements, which are largely influenced by the local agro-climatic parameters of the selected crop reporting districts (CRDs) of the United States. For the farming system, LCI information, as shown in the data are averaged from the respective CRDs. LCI data for the post-harvest stages are based on available information from the relevant processing plants and the engineering estimates. The article also briefly presents the assumptions made for evaluating future crop production scenarios. Future scenarios integrate the impact of climate change on the future productivity and evaluate the effect of adaptation measures and technological advancement on the crop yield. The provided data are important to understand the characteristics of the food supply chain, and their relationships with the life cycle environmental impacts. The data can also support to formulate potential environmental mitigation and adaptation measures in the food supply chain mainly to cope with the adverse impact of climate change.
