**2.2.1 Top-down approach**

A generic set was built up through the combination of already existing templates:


This generic set was modified during three workshops from May to June 2010, at national (Xuan Mai University of Hanoi), province (Thai Nguyen University of Agriculture and Forestry) and district level (Cho Chu, the Dinh Hoa District centre). The participants could eliminate, modify and add elements to the set.

Three tools were used during these workshops: rankings, ratings and pairwise comparisons, following the Multi-Criteria Decision Making (MCDM) application guidelines from CIFOR (CIFOR, 1999a), and its applications (Mendoza and Prabhu, 2000a; Mendoza and Prabhu, 2000b; Andrada II and Calderon, 2008; Gomontean et al., 2008; Ritchie et al., 2000). The proceeding lead to one final C&I set per workshop.
