What will France be like in 2015? Is there a way to avoid the dangers of its marginalization in Europe or its dislocation? What can be done to relieve overcrowded urban areas and stop the depopulation of rural regions. Reconstructing the French territory is a necessity, but the question is how. Drawing on research conducted by DATAR’s forecast studies department, Jean-Louis Guigou presents here his thoughts and observations. He indicates some potential directions and outlines a ‘desirable scenario’ for France in the year 2015. This incisive, personal study, first published in French in 1993, is an essential contribution to the national debate.
