“…Several studies have also focused on accessibility to fresh and healthy foods regarding nutrition [60,61] or shopping behavior [62,63], with many including spatial data in their analysis [64][65][66][67][68]. Some studies have also accounted for spatial effects on food consumption or accessibility using spatial econometric models [69][70][71][72]. To the best of our knowledge, only one other study [53] has analyzed the accessibility of organic food with neighborhood or resident characteristics and found that the location of organic food retailers was positively associated with population density, education, and median housing value, with no disparities based on income.…”

Shifting the food system to a more sustainable one requires changes on both sides of the supply chain, with the consumer playing a key role. Therefore, understanding the factors that positively correlate with increased organic food sales over time for an entire population can help guide policymakers, industry, and research to increase this transition further. Using a statistical approach, we developed a spatial pooled cross-sectional model to analyze factors that positively correlate with an increased demand for organic food sales over 20 years (1999–2019) for an entire region (the city-state of Hamburg, Germany), accounting for spatial effects through the spatial error model, spatially lagged X model, and spatial Durbin error model. The results indicated that voting behavior strongly correlated with increased organic food sales over time. Specifically, areas with a higher number of residents that voted for a political party with a core focus on environmental issues, the Greens and the Left Party in Germany. However, there is a stronger connection with the more “radical” Left Party than with the “mainstream” Green Party, which may provide evidence for the attitude-behavior gap, as Left Party supporters are very convinced of their attitudes (pro-environment) and behavior thus follows. By including time and space, this analysis is the first to summarize developments over time for a metropolitan population while accounting for spatial effects and identifying areas for targeted marketing that need further motivation to increase organic food sales.

“…Other mapping studies have included infrastructural features of neighborhoods, such as roads, bus routes, sidewalks, and bicycle paths, and estimates of travel time to assess the impact of physical distances and locations on food access for residents (Kolak et al, 2018;Widener et al, 2011). Spatial statistical tools (Cressie, 2015) exist to help researchers account for spatial clustering and autocorrelation in quantitative analyses of food availability and access (e.g., Benez-Secanho et al, 2021). These etic mapping approaches have been criticized on several grounds including their narrow focus on physical distance and purchasing power as determinants of urban food access (Shannon et al, 2021;Taylor & Ard, 2015).…”

Objective: Food insecurity is a significant and growing concern undermining the wellbeing of 30% of the global population. Food in/security is a complex construct consisting of four dimensions: availability, access, utilization, and stability, making it challenging to measure. We provide a toolkit human biologists/ecologists can use to advance research on this topic.Methods: We review the strengths and limitations of common tools used to measure food access and utilization, the two dimensions most proximate to people's lived experience, and emphasize tools that provide data needed to best link food security with human biological outcomes. We also discuss methods that provide contextual data human biologists/ecologists will find useful for study design, ensuring instrument validity, and improving data quality.Results: Food access is principally measured using experience-based instruments that emphasize economic access. Social access, such as food sharing, is under-studied and we recommend using social network analysis to explore this dimension. In terms of utilization, emphasis has been on food choice measured as dietary diversity. Food preparation and intrahousehold distribution, also part of the utilization dimension, are less studied and standardized instruments for measuring both are lacking. The embodiment of food insecurity has focused on child growth, although a growing literature addresses adult mental wellbeing and chronic and infectious disease risk.Conclusions: We see the potential to expand outcomes to include reproductive and immune function, physical activity, and the gut microbiome. Human biologists/ecologists are well-positioned to advance understanding of the human health impacts of food insecurity and provide data to support intervention efforts.
