Les Ateliers is a non-governmental organization that gathers universities, decision makers and professionals dedicated to planning, development and urban design. Since 1982, les ateliers has been organizing international workshops on topics defined together with local authorities for city or regional planning. The method consists in gathering students or professionals of different nationalities and different specializations (landscape designers, architects, engineers, economists...), and make them work in different teams that finally present their proposals to an international jury composed of local authorities and international experts. Each workshop offers to local authorities new and innovative urban development proposals, assessed by the members of the jury and transcribed into a synthesis delivered 2 months after the workshop. These workshops are also a source of training for all the participants, whether they be local or international experts.
