Facility locations in the fresh produce supply chain: An integration of optimization and empirical methods

Facility locations are crucial determinants of supply chain efficiency for aggregating and distributing products. The multi-disciplinary nature of the facility location problem requires multiple complementary approaches, at different levels of aggregation, to accommodate the salient features of location determinants. This study examines the facility location problem for the U.S. fresh produce supply chain. We present a model that incorporates an empirical scenario into a facility location problem in order to capture much of the information required to make an optimal location decision. Our results suggest that the reliability of facility locations can be improved without significantly increasing the operating costs. This study sheds light on how the application of complementary modeling approaches improves the effectiveness of facility location solutions.

Five Decades of Modeling Supporting the Systems Ecology Paradigm

Ecosystem modeling, a pillar of the systems ecology paradigm (SEP), addresses questions such as, how much carbon and nitrogen are cycled within ecological sites, landscapes, or indeed the earth system? Or how are human activities modifying these flows? Modeling, when coupled with field and laboratory studies, represents the essence of the SEP in that they embody accumulated knowledge and generate hypotheses to test understanding of ecosystem processes and behavior. Initially, ecosystem models were primarily used to improve our understanding about how biophysical aspects of ecosystems operate. However, current ecosystem models are widely used to make accurate predictions about how large-scale phenomena such as climate change and management practices impact ecosystem dynamics and assess potential effects of these changes on economic activity and policy making. In sum, ecosystem models embedded in the SEP remain our best mechanism to integrate diverse types of knowledge regarding how the earth system functions and to make quantitative predictions that can be confronted with observations of reality. Modeling efforts discussed are the Century ecosystem model, DayCent ecosystem model, Grassland Ecosystem Model ELM, food web models, Savanna model, agent-based and coupled systems modeling, and Bayesian modeling.

The profitability implications of sales through local food markets for beginning farmers and ranchers

The Agriculture Improvement Act of 2018 directed the US Secretary of Agriculture to report on the profitability and viability of beginning farmers and ranchers. Many beginning operations use local food markets as they provide more control, or a premium over commodity prices, and beginning operations cannot yet take advantage of economies of scale and subsequently have higher costs of production. Little research assesses the relationship between beginning farmer profitability and sales through local food markets. In this paper, the profitability implications of sales through local food markets for beginning farmers and ranchers are explored.

Exploring the relationships among stocks of community wealth, state farm to school policies, and the intensity of farm to school activities

Farm to School (FTS) is a widely implemented public food procurement program in the U.S., and the number of state and Federal policies promoting it continue to grow. However, previous research has found inconclusive results associated with state-level policies. One reason may be that FTS adoption is associated with different stocks of community wealth (assets including human, social, and financial capital, net of liabilities). This research leverages the U.S. Department of Agriculture’s 2019 FTS Census, a new disaggregated database on state-level FTS policies, and a new comprehensive dataset of stocks of community wealth to assess this relationship. We find positive associations between cultural and social capital and FTS intensity (an index representing the extent of FTS participation), highlighting community assets that are often overlooked in community development programs. Further, we find that different types of state FTS policies are associated with FTS intensity; procurement policies have positive associations and education policies have negative associations. Results provide rationale for more nuanced consideration of local assets in prioritizing the types of FTS policy.

Economic impact assessment of public incentives to support farm-to-school food purchases

Abstract: Farm-to-school projects have been widely supported by policy makers with funding provided at state and federal levels. Still, many of the outcomes of this inflow of policy and funding remain unclear, often due to insufficient data to examine them. In 2018, New York State (USA) announced the 30% NY Initiative that substantially increases school lunch reimbursements if school districts purchase at least 30% of their ingredients as New York food products. With detailed food purchasing data from the second largest school district in the state and the largest to qualify for enhanced reimbursement, we estimate the gross and net economic impacts of the policy through a customized input–output model. We observe clear shifts in food spending categories that suggest changes in what and where foods were purchased. Results demonstrate net positive value added impacts of the policy even when a negative impact is applied to account for the cost of the policy to taxpayers. For every dollar in gross domestic product lost in the state to support the program, $1.06 of gross domestic product is expected to be added. However, the results are only true to the extent that the increase in local food spending is commensurate with an expansion of the related farm and food product industries to meet that demand. Specifically, at least 67% of the growth in local food spending must contribute to new aggregate demand for the related food product industries, rather than reallocation from other local marketing channels.
