Study Methodology

Over two consecutive years, ADBI and the Rural Enterprise Development Programme (REDP) supported three surveys of a total of ninety-six persons including owners of distillation units, operators employed at distillation units, and grass and firewood collectors from organic and conventional management groups in Drametse gewog. The surveys were based on structured questionnaires developed in collaboration with ADBI, NOP and Bio Bhutan.3 A total of eight enumerators were deployed for a period of two weeks to conduct the first survey in June 2006. Two follow-up surveys to complement the results of the first round were carried out with the involvement of a national consultant employed by the REDP in October 2007 (Trumps International Consultancy Services, 2006).

While the main objective of this study was to examine income generation and sustainable management practices through LGO production, the survey also included questions on the impact on overall household income and expenditure, food security, migration, empowerment of women, maternal health and child mortality, and the occurrence of malaria and other diseases. Where relevant, the evaluation and findings from the secondary data have been included in the presentation and discussion of results of this study.

Sample size: Out of a total of 41 distillers in Drametse gewog,4 12 distillers (nine conventional distillers, three distillers applying organic standards) were selected through random sampling, meaning that the survey covered 29% of the distillers of Drametse gewog and 7% of the estimated 172 distillers in eastern Bhutan.
