1	Arizona Foodshed: Estimating Capacity to Meet Fresh Fruit and Vegetable Consumption Needs of the Arizona Population January 2013 (has links) abstract: Fruit and vegetable (FV) consumption continues to lag far behind US Department of Agriculture (USDA) recommendations. Interventions targeting individuals' dietary behaviors address only a small fraction of dietary influences. Changing the food environment by increasing availability of and excitement for FV through local food production has shown promise as a method for enhancing intake. However, the extent to which local production is sufficient to meet recommended FV intakes, or actual intakes, of specific populations remains largely unconsidered. This study was the first of its kind to evaluate the capacity to support FV intake of Arizona's population with statewide production of FV. We created a model to evaluate what percentage of Dietary Guidelines for Americans (DGA) recommendations, as well as actual consumption, state-level FV production could meet in a given year. Intake and production figures were amended to include estimates of only fresh, non-tropical FV. Production was then estimated by month and season to illustrate fluctuations in availability of FV. Based on our algorithm, Arizona production met 184.5% of aggregate fresh vegetable recommendations, as well as 351.9% of estimated intakes of Arizonans, but met only 29.7% of recommended and 47.8% of estimated intake of fresh, non-tropical fruit. Much of the excess vegetable production can be attributed to the dark-green vegetable sub-group category, which could meet 3204.6% and 3160% of Arizonans' aggregated recommendations and estimated intakes, respectively. Only minimal seasonal variations in the total fruit and total vegetable categories were found, but production of the five vegetable sub-groups varied between the warm and cool seasons by 19-98%. For example, in the starchy vegetable group, cool season (October to March) production met only 3.6% of recommendations, but warm season (April to November) production supplied 196.5% of recommendations. Results indicate that Arizona agricultural production has the capacity to meet a large proportion of the population's FV needs throughout much of the year, while at the same time remaining a major producer of dark-green vegetables for out-of-state markets. / Dissertation/Thesis / M.S.

2	Measuring the Shape and Size of the Foodshed Forkes, Jennifer 30 August 2011 (has links) This thesis explores indicator tools to measure the ecological impacts of changes to the food system. The concept of a ‘foodshed’ provides a framework to explore the relationships between ecological impacts and where food system activities occur. Indicators of resource use and reuse are developed to describe the shape and size of the foodshed. Paper 1 presents a review of six indicator-based tools from the literature. Using a three criteria definition of ecological sustainability in the food system - increased resource efficiency, decreased pollutant loading, and increased output reuse - Paper 1 examines the suitability of these tools for evaluating the impacts of municipal food policy driven-changes in the location of activities, processes within activities and diet composition. Paper 2 describes the shape of a foodshed, and investigates how changes in Toronto’s waste management impacted the reuse of food-related nitrogen. Reuse increased from 1% in 1990 to at least 4.7% in 2001, through backyard composting and the land application of processed sewage. By 2004, in spite of household organics collection, reuse decreased to 2.3%, due to a reduction in land-applied sewage. The analysis suggests that sewage management has a larger impact on the reuse of food nitrogen than household solid waste management. Paper 3 quantifies the size of the foodsheds of Canada and the Greater Toronto Area (GTA), and evaluates the feasibility of self-sufficiency and its impact on the total land area used for production. Nationally, there is sufficient harvested land area to meet 95% of the land area needed for self-sufficiency. Self-sufficiency is only feasible for the GTA by drawing from a foodshed extending 400 kilometres beyond its boundary. Given current yields, total self-sufficiency would occupy more land area than currently used domestically and abroad. Higher yields or a change in diet could decrease the size of the foodshed. food systems nutrient cycling land use foodshed indicators ecological sustainability 0366 0768

4	Designing a Foodshed Assessment Model: Guidance for Local and Regional Planners in Understanding Local Farm Capacity in Comparison to Local Food Needs Blum-evitts, Shemariah 01 January 2009 (has links) (PDF) This thesis explores how to conduct a regional foodshed assessment and further provides guidance to local and regional planners on the use of foodshed assessments. A foodshed is the geographic origin of a food supply. Before the 1800s, foodsheds were predominantly local — within the city or neighboring countryside. Today most urban areas are supported by a global foodshed. While the global foodshed can present many benefits, it also creates tremendous externalities. In an attempt to address these concerns, promotion of alternative local foodsheds has re-emerged. A foodshed assessment serves as a planning tool for land use planners, as well as for local food advocates, offering an understanding of land use implications that is not often carefully considered. By determining the food needs of a region’s population, the land base needed to support that population can then be identified. In this way, planners can have a stronger basis for promoting working farmland preservation measures and strengthening the local foodshed. This thesis compares the approaches of five previous foodshed assessments and presents a model for conducting an assessment on a regional level. This model is then applied to the Pioneer Valley of Western Massachusetts with the goal of determining how much the agricultural production in the Pioneer Valley fulfills the food consumption needs of the region’s population. The assessment also compares the amount of current working farmlands to open lands available for farming, and the extent of farmland necessary to meet regional food demand for various diet types. foodshed local food land use food supply agriculture planning Regional planning & development Architecture Urban, Community and Regional Planning
