摘要：As part of a pilot project, a decision making assistance tool was developed; this was done considering the high sensitivity to rainfall variability in rice crops over the coastal region of Ecuador. Through land cover, demographic distribution, topography, flooding geospatial information at 1:50.000 scale, and socio economic impacts statistics, vulnerability estimation was per formed. This approach was based on the combination of "exposure to risk" with "coping capacity". Processed vulnerability maps during a rainy season in Ecuador (January-May 2005), were compared with the documented impacts in rice crops in the area during the same period showed a fairly acceptable correlation between them (more than 65%).Risk maps were distributed to community leaders and other local contacts. Distribution of vulnerability maps to potential users in Ecuador has lead to the increasing of a distribution list of more than 200 direct users of the information with the capacity to spread this information to their groups. Most of the comments received, pointed out the usefulness of this information during the period previous to seeding time. The estimated number of direct and indirect beneficiaries of the project in its first phase was close to 10.000 rice farmers in Ecuador. The approach demonstrated to be fairly close for referential purposes. Feedback from the users suggest that all this information was applicable and easy to understand, however most efforts on awareness and training for more application of this tool must be achieved to maximize benefits in local populations
