3/2000 – 8/2001:
Participation and Gender Specialist, CATIE-MIP/AF, Managua, Nicaragua.  This was a regional IPM program, the goal of which was to improve pest-management practices of farm families through ecological reasoning and systematic observation.  A major focus was on training of trainers (extensionists).  As a member of the management team supervised two staff specialists in participatory methods and gender inclusion issues.  Assessed methodological content of season-long training of trainers in IPM, and facilitated increased incorporation of participatory methods and a family focus into the training.  Developed curricula and trained farmers, trainers and master-trainers in participatory implementation of IPM.
