To test the questionnaire, a pre-survey was conducted among 20 farmers who were not included in the final survey. The pre-survey aimed to evaluate the feasibility of the questionnaire draft, the time needed for planning the survey, and whether the results were in line with the survey goals. Based on the results, the questionnaire draft was slightly edited, resulting in the final questionnaire.
For the final questionnaire, 174 farmers were surveyed in eight districts at different elevations along the UCRB (Figure 1), i.e. Lembang (n=26), Cihampelas (n=32), Solokan Jeruk (n=28), Ciparay (n=18), Majalaya (n=20), Pacet (n=7), Pangalengan (n=12), and Ciwidey (n=31). The survey was conducted between January and March 2016. For every location, we were accompanied by a local guide who was known in the local community and farmers were selected by walking the area and randomly selecting farms to visit.
