Global warming and navy beans: Decision making by farmers and food companies in the U.K.

Farmers are continually adjusting their business enterprises in response to the shifting economic, political and social pressures which affect each aspect of their production. These adjustments may include structural changes, agronomic (production) changes or moves into ‘diversification’ enterprises, and are manifest at different scales, from the farm unit to changes in a country's or region's agricultural structure. One factor influencing future changes in agriculture is likely to be climate change (‘global warming’) which will alter the physical environmental conditions of production. The consequences of this might include a change in the crop species cultivated in different areas. This paper examines the responses of farmers in part of southern Britain to the possibility of growing navy beans, a crop used for baked bean manufacture and obtained almost wholly from North America, as a response to a warmer climate. The paper seeks to explore the network of relations at the farm, national and international scales which will determine the likelihood of commercial adoption of the crop occurring in the U.K. Through discussion of the results of interviews with farmers, food processing companies and associated agencies it is concluded that there are significant structural barriers to the adoption of navy beans as a diversification option on U.K. farms as a result of international trade restraints and a measure of inertia and risk aversion within the processing companies.
