In the context of different projects, some participatory methods were used,
together with more traditional ones, in a research process aimed at elicit
ing local knowledge about risks derived from industrial activities. The pol
icy implications of this approach are towards promoting citizen awareness a
nd encouraging their involvement in actions addressed to reducing community
vulnerability to risks. The paper illustrates the objectives and methodolo
gy of a project on public risk perception and comments on some of its findi
ngs. Drawing also from other research experiences, it outlines a set of 'pr
inciples' which can guide the interpretation of citizens' concerns and aspi
rations. (C) 2000 Elsevier Science B.V. All rights reserved.
