• Avoiding the local trap : scale and food systems in planning research
  3 novembre 2021, par Mathilde COUDRAY

  A strong current of food-systems research holds that local food systems are preferable to systems at larger scales. Many assume that eating local food is more ecologically sustainable and socially just. We term this the local trap and argue strongly against it. We draw on current scale theory in political and economic geography to argue that local food systems are no more likely to be sustainable or just than systems at other scales. The theory argues that scale is socially produced : scales (and their interrelations) are not independent entities with inherent qualities but strategies pursued by social actors with a particular agenda. It is the content of that agenda, not the scales themselves, that produces outcomes such as sustainability or justice. As planners move increasingly into food-systems research, we argue it is critical to avoid the local trap. The article’s theoretical approach to scale offers one way to do so.

• Small farm production and the standardization of tropical products
  26 octobre 2021, par Mathilde COUDRAY

  This paper explores the historical relations between labour organization and product qualification in the production of tropical agricultural exports. In supplying international markets for tropical products, peasant farming emerged as the norm for labour organization after the First World War, competing with the large plantations and different systems of forced labour. During the same period, national standards became the dominant tool for product qualification of commodities traded on the global agricultural markets. These standards allow the creation of futures markets and the emergence of traders, instead of auction markets and commission merchants : two changes that were the basis of the subsequent international marketing of peasant-produced commodities. The last part of the paper considers the potential consequences of the current erosion of standards for the position of peasants in tropical export crop cultivation.

• Food swamps predict obesity rates better than food deserts in the United States
  3 novembre 2021, par Mathilde COUDRAY

  This paper investigates the effect of food environments, characterized as food swamps, on adult obesity rates. Food swamps have been described as areas with a high-density of establishments selling high-calorie fast food and junk food, relative to healthier food options. This study examines multiple ways of categorizing food environments as food swamps and food deserts, including alternate versions of the Retail Food Environment Index. We merged food outlet, sociodemographic and obesity data from the United States Department of Agriculture (USDA) Food Environment Atlas, the American Community Survey, and a commercial street reference dataset. We employed an instrumental variables (IV) strategy to correct for the endogeneity of food environments (i.e., that individuals self-select into neighborhoods and may consider food availability in their decision). Our results suggest that the presence of a food swamp is a stronger predictor of obesity rates than the absence of full-service grocery stores. We found, even after controlling for food desert effects, food swamps have a positive, statistically significant effect on adult obesity rates. All three food swamp measures indicated the same positive association, but reflected different magnitudes of the food swamp effect on rates of adult obesity (p values ranged from 0.00 to 0.16). Our adjustment for reverse causality, using an IV approach, revealed a stronger effect of food swamps than would have been obtained by naïve ordinary least squares (OLS) estimates. The food swamp effect was stronger in counties with greater income inequality (p < 0.05) and where residents are less mobile (p < 0.01). Based on these findings, local government policies such as zoning laws simultaneously restricting access to unhealthy food outlets and incentivizing healthy food retailers to locate in underserved neighborhoods warrant consideration as strategies to increase health equity.
