The long durée: A question of sustainability

In the Brundtland Commission’s classic formulation, sustainability is defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

In this context, the article’s contribution is to operationalize the concept of sustainability in five dimensions: First, and in a very general sense, it emphasizes the space-time dimension, where the spatial dimension is potentially global, and the temporal dimension potentially infinite. This is followed by four key aspects for defining the content of the concept: self-sustainability, systemic holism, precaution and resilience.
