The trente glorieuses, “thirty glorious years” of rapid postwar modernization, transformed France into an efficient agricultural powerhouse between 1950 and 1980. Deep structural changes benefitted those able to become modern farmers and precipitated the economic collapse of small peasant farms. Poor, remote regions emptied as young people left for jobs and a higher standard of living in cities. The modernization of agriculture was part of a state-led program of targeted regional development and planning carried out under the auspices of the DATAR, France’s national agency for “territorial balancing.” Ultimately urban development, the decentralization of industry, and the building of a modern infrastructure for communication, transportation, and energy production took precedence over the needs of agriculture. New demands placed on rural space for residential use, tourism and recreation, and protected natural sites created a multiuse landscape. Not only were farmers no longer peasants, the countryside was no longer just farmland.
