Popis: This paper assesses the origins of water-related vulnerabilities among the Andean populations of the Rio Mocoties valley in Venezuela, which was struck by deadly floods and mudslides (la vaguada) in February 2005. The paper stresses the role played in this social disaster by changes in agricultural practices and in land uses (deforestation, the conversion of agricultural surfaces, urban growth). Its methodology is based on the cross-referencing of cartographic data―obtained thanks to satellite images (ISIS SPOT 2012 Program) or aerial pictures―and sociological surveys in order to show the parallel perception of the evolution of land uses between instrumental and human points of view. Beyond the social situation and the extent of the changes which can be observed on the slopes of this watershed, this paper will show how the discourse on vulnerability factors may vary according to the actors at play (village dwellers, farmers, elected officials)―thus proving the fundamental link between social representations and the perception of water-related risks.
