“…Despite the closer proximity of supermarkets in urban areas, which facilitated fruit consumption [35], it took longer for those living in the least wealthy neighbourhoods to access supermarkets and vegetable and fruit stores [56]. This finding was consistent with previous studies that took place in Western countries regarding the effects of socioeconomic status on accessibility to food stores [4]. This finding could be explained by lowincome consumers' inability to afford rent for properties near food businesses.…”

“…Thus, the promotion and consumption of FVs could save many lives. Compared to dietary interventions on an individual level, public-policy interventions on a community level, such as changing the food environment, have shown more potential to promote FV consumption and subsequently a considerable reduction of diseases attributable to insufficient FV intake [4]. Evidence shows that food choice is not merely determined by individuals but influenced by social and physical environments [5].…”

Fruit and vegetable (FV) consumption benefits the health of populations, particularly those in East and Southeast Asian countries, which have undergone an unprecedented change in their food environments in the last decade. This current systematic review is the first to study determinants—facilitators, barriers, and moderators—associated with FV consumption in East and Southeast Asia. In a search of the literature, we consulted five electronic academic databases of English peer-reviewed papers published between 2010 and 2020 and found 31 studies. Results of these studies show that individuals strongly perceive FVs as being higher quality and safe and trust in their benefits, and food businesses with modernized systems have significantly fostered the consumption of FVs. A main barrier to FV consumption, however, is financial concerns, exacerbated by food businesses with FV unavailability and urbanization-induced FV price inflation and dietary patterns. Further hindering FV consumption are demographics and shopping patterns. The fragmented and conditionalized findings of the 31 studies require standardized FV consumption measurements. Unlike the impact of FV consumption determinants and their interactions in Western countries, those in Asia, particularly countries other than China, have been substantially understudied. Therefore, as the research gaps in studies of food environments and FV consumption in East and Southeast Asia urgently demand scholarly attention, this paper proposes recommendations that favour the consumption of FVs.

“…Limited physical and economic access to food, including poor overall urban planning, deficient or non-existent public transport, urban decay, and generalised poverty have been cited as factors favouring the development of food deserts. Overall policies to improve purchasing power for food, combined with local policies (such as strategic planning for grocery stores establishment, based on population density, spatial poverty distribution, and access to transport), have been considered as effective ways to control and reduce food deserts (Koh et al 2019 ).…”

This opinion article results from a collective analysis by the Editorial Board of Food Security. It is motivated by the ongoing covid-19 global epidemic, but expands to a broader view on the crises that disrupt food systems and threaten food security, locally to globally. Beyond the public health crisis it is causing, the current global pandemic is impacting food systems, locally and globally. Crises such as the present one can, and do, affect the stability of food production. One of the worst fears is the impacts that crises could have on the potential to produce food, that is, on the primary production of food itself, for example, if material and non-material infrastructure on which agriculture depends were to be damaged, weakened, or fall in disarray. Looking beyond the present, and not minimising its importance, the covid-19 crisis may turn out to be the trigger for overdue fundamental transformations of agriculture and the global food system. This is because the global food system does not work well today: the number of hungry people in the world has increased substantially, with the World Food Programme warning of the possibility of a “hunger pandemic”. Food also must be nutritious, yet unhealthy diets are a leading cause of death. Deepening crises impoverish the poorest, disrupt food systems, and expand “food deserts”. A focus on healthy diets for all is all the more relevant when everyone’s immune system must react to infection during a global pandemic. There is also accumulating and compelling evidence that the global food system is pushing the Earth system beyond the boundaries of sustainability. In the past twenty years, the growing demand for food has increasingly been met through the destruction of Earth’s natural environment, and much less through progress in agricultural productivity generated by scientific research, as was the case during the two previous decades. There is an urgent need to reduce the environmental footprint of the global food system: if its performances are not improved rapidly, the food system could itself be one main cause for food crises in the near future. The article concludes with a series of recommendations intended for policy makers and science leaders to improve the resilience of the food system, global to local, and in the short, medium and long term.

“…Another article of note is by Koh et al [ 29 ], who report on an ABM that emulates the urban food environment in Columbus (Ohio), U.S. Household agents, equipped with selected sociodemographic characteristics, shop in supermarkets based on empirically derived probabilities. The major output of the model is food availability per household, measured using a monthly food availability index.…”

The dynamics of food shopping behavior: Exploring travel patterns in low-income Detroit neighborhoods experiencing extreme disinvestment using agent-based modeling

Only a handful of studies have leveraged agent-based models (ABMs) to examine public health outcomes and policy interventions associated with uneven urban food environments. While providing keen insights about the role of ABMs in studying urban food environments, these studies underutilize real-world data on individual behavior in their models. This study provides a unique contribution to the ABM and food access literature by utilizing survey data to develop an empirically-rich spatially-explicit ABM of food access. This model is used to simulate and scrutinize individual travel behavior associated with accessing food in low-income neighborhoods experiencing disinvestment in Detroit (Michigan), U.S. In particular, the relationship between trip frequencies, mode of travel, store choice, and distances traveled among individuals grouped into strata based on selected sociodemographic characteristics, including household income and age, is examined. Results reveal a diversified picture of not only how income and age shape food shopping travel but also the different thresholds of tolerance for non-motorized travel to stores. Younger and poorer population subgroups have a higher propensity to utilize non-motorized travel for shopping than older and wealthier subgroups. While all groups tend to travel considerable distances outside their immediate local food environment, different sociodemographic groups maintain unique spatial patterns of grocery-shopping behavior throughout the city and the suburbs. Overall, these results challenge foundational tenets in urban planning and design, regarding the specific characteristics necessary in the built environment to facilitate accessibility to urban amenities, such as grocery stores. In neighborhoods experiencing disinvestment, sociodemographic conditions play a more important role than the built environment in shaping food accessibility and ultimately travel behavior.
