Decoding Diversity in the Food System: Wheat and Bread in North America

Diversity is important for the resilience of food systems, as well as for its own sake. Just how diverse are the systems that produce our food? I explore this question with a focus on wheat and bread and North America, and even more specifically in baking, milling and farming. Although the opacity of food and agricultural systems makes definitive answers difficult, these segments appear to be increasingly uniform with respect to ownership, geography, varieties and genes. There are also important countertrends, and while efforts to resist uniformity are currently small, they are making some progress in maintaining or even increasing diversity in some areas.

The illusion of diversity: visualizing ownership in the soft drink industry

Three firms control 89% of US soft drink sales. This dominance is obscured from us by the appearance of numerous choices on retailer shelves. Steve Hannaford refers to this as “pseudovariety,” or the illusion of diversity, concealing a lack of real choice. To visualize the extent of pseudovariety in this industry we developed a cluster diagram to represent the number of soft drink brands and varieties found in the refrigerator cases of 94 Michigan retailers, along with their ownership and/or licensing connections.

Concentration in the U.S. Wine Industry

No other section of the supermarket offers as many choices as the wine aisle. A typical retailer is likely to have hundreds of unique wines on its shelves. Just three firms, however, account for more than half of the wine sales in the United States. What impact does this industry concentration have on consumer choices? To answer this question we conducted an inventory of wine offerings at 20 retailers in Michigan. We recorded more than 3,600 unique varieties of wine, and traced their relationships with more than 1,000 different firms. Continue reading Concentration in the U.S. Wine Industry

Visualizing Fair Trade Coffee

The fair trade certification has entered a period of major change. The recent departure of Fair Trade USA from the international certification system led by Fair Trade International (formerly FLO), and its decision to develop separate US standards that permit certification of plantation-produced coffee, cocoa, and other crops, has thrown the meaning of the US fair trade label into question.
