This led to a smaller sample of schools reducing the sample size and variability within the different demographic populations. Additionally, this study focused on tenth grade high school students; sampling older or younger students may elicit different perceptions, behavior, and knowledge of the food system.
Knowing if there are disconnects in adolescent views of access to heathy food and what is in the neighborhood environment better informs assessments of food systems. The purpose of this research was to understand student perceptions of our expanding and complex food system. Reporting patterns of student knowledge, attitudes, and behavior collectively and their differences among demographics provides information that can be used in frameworks e.

Such information can inform decision makers at different scales from local to national. Additionally, there is more confusion when food items are less common.
The results of this study also indicate that the majority of food purchases across demographics come from a grocery store, while big box stores remain popular for urban cluster students, and hunting was more common for rural students as a source of food than any other demographic. Overall, students did recognize that agriculture is an important structure in the economy and for our food sources.
While students acknowledged that they were not taught about food systems often in school, there is consensus that they want to learn more and would welcome further instruction in the schools. The study found that there were differences and similarities between the three different demographics filling the data need for more information concerning adolescent actors in the food system.
By dividing the urban demographic into two different categories more insight into adolescent actors was gained concerning urban demographics. Besides informing frameworks on food systems, the study provides information on adolescent knowledge that is informative to food system educators, but also professionals in the agriculture industry and extension who focus on outreach measures to engage youth and increase knowledge.

HortTechnology 15 3 : — Impact of garden-based youth nutrition intervention programs: A review. Following several years of below-average precipitation and above-average temperatures, a State of Emergency due to drought was declared in [ 24 ]. The State of Emergency was lifted in April [ 26 ].
As the drought progressed across California, several failures of basic events in the fault tree occurred throughout the state. These failures of basic events span several subtrees within our model. This example demonstrates that the fault tree model can be used as a tool to analyze the effects of events geographically removed from the local food system under investigation.
Despite California being the largest agricultural supplier in the United States, decreases in production resulting from drought exerted minimal effects on the food system of Baltimore City. Although basic and intermediate events occurred in two subtrees throughout the course of the drought, system failure did not occur because of the diversity of the global food system supplying Baltimore. In a multi-year drought, actors within the food system were able to source produce from alternate locations or offer substitutions for produce which was in short supply or too expensive.
