Food Environment Typology: Advancing an Expanded Definition, Framework, and Methodological Approach for Improved Characterization of Wild, Cultivated, and Built Food Environments toward Sustainable Diets
(2020-04) Downs, Shauna M.; Ahmed, Selena; Fanzo, Jessica; Herforth, Anna
The food environment is a critical place in the food system to implement interventions to support sustainable diets and address the global syndemic of obesity, undernutrition, and climate change, because it contains the total scope of options within which consumers make decisions about which foods to acquire and consume. In this paper, we build on existing definitions of the food environment, and provide an expanded definition that includes the parameter of sustainability properties of foods and beverages, in order to integrate linkages between food environments and sustainable diets. We further provide a graphical representation of the food environment using a socio-ecological framework. Next, we provide a typology with descriptions of the different types of food environments that consumers have access to in low-, middle-, and high-income countries including wild, cultivated, and built food environments. We characterize the availability, affordability, convenience, promotion and quality (previously termed desirability), and sustainability properties of food and beverages for each food environment type. Lastly, we identify a methodological approach with potential objective and subjective tools and metrics for measuring the different properties of various types of food environments. The definition, framework, typology, and methodological toolbox presented here are intended to facilitate scholars and practitioners to identify entry points in the food environment for implementing and evaluating interventions that support sustainable diets for enhancing human and planetary health.

The global food environment transition based on the socio-demographic index
(Elsevier BV, 2022-06) Downs, Shauna M.; Ahmed, Selena; Warne, Teresa; Fanzo, Jessica; Loucks, Kelly
Food environments are a critical point for reorienting the food system towards sustainable diets, as they are directly where consumers make decisions about which foods to acquire. Using global data, we examined shifts in food environments, and the availability, affordability, convenience, and quality of foods within them, over time on the basis of socio-demographic index (SDI) country groupings. Our findings provide evidence of a food environment transition where built environments have shifted from traditional to modern retail outlets between 2005 and 2019 and the availability and affordability of nutrient-rich foods has increased alongside growing sales of ultra-processed and ready-to-eat foods. This transition has implications for the identification of policy and program levers for promoting healthy and sustainable diets and reducing malnutrition globally.
Rapid tool based on a food environment typology framework for evaluating effects of the COVID-19 pandemic on food system resilience
(2020) Ahmed, Selena; Downs, Shauna M.; Yang, Chunyan; Chunlin, Long; Ten Broek, Noah; Ghosh-Jerath, Suparna
The coronavirus disease 2019 (COVID-19) and associated mitigation measures are highlighting resiliency and vulnerability of food systems with consequences for diets, food security, and health outcomes. Frameworks and tools are called for to evaluate impacts of the COVID-19 pandemic as well as identify entry points for implementing preparedness efforts. We support it is critical to adopt a food environment typology framework based on the different types of food environments that people have access to in order to examine how their relationship with food environments shift with disruptions such as COVID-19 and, ultimately impact diets and food security. Here, we provide an overview of applying a food environment typology framework for developing and implementing a rapid tool to evaluate the effects of COVID-19 on interactions people have with their food environments. This tool was developed on the basis of a preliminary case study with smallholder farmers in China that generated a set of key hypotheses. We modified the tool in order to be applicable to diverse contexts in low-, middle-, and high-income countries. Other researchers can implement the rapid tool presented here during times of COVID-19 as well as other disruptions towards identifying barriers and opportunities for enhancing food system resilience.
