Natural reforestation and growth of brushwood on the Méjean limestone plateau: the value of a combined approach between natural and social sciences

Abstract

The spontaneous reforestation of agricultural land is studied from an interdisciplinary point of view involving natural science and social science. Depending on the scale on which the phenomena is studied, various sources and methods for data processing are used. Natural science and social science data are crossed in parallel by multivariable analysis and by the geographical data system (SIG). Various hypotheses explaining the progression of ligneous vegetation are thus tested and arranged by order of importance.
