In this paper we report our attempts to evaluate the achievements of a project whose main purpose is, through applied research and participatory information exchange, to influence the environmental awareness, attitudes and practices of a group of mainly farm households in a Philippine watershed. Part of the project involves scientists engaging in applied research on water quality, soil management, and forest management by community members. The methods used to disseminate and acquire feedback on this research are mainly very informal. The output of the information exchange is hard to quantify, and moreover, attribution to the project is problematic when similar information may emanate from several sources and find its way to individuals by numerous paths. We report on a survey in which we attempted to minimize these difficulties.
