The research for this thesis utilizes a new participatory research technique called Domain Analysis to understand farmers' knowledge regarding the values o f agricultural biodiversity. The Domain Analysis technique is applied toward two case studies featuring the mixed cropping practices of the Kuvi and Korku Adivasi tribes of India. The findings of the research indicate that these farmers employ mixed cropping practices because they offer stable and diverse food and economic security by maximizing resiliency against unpredictable ecological conditions despite minimal external inputs. In addition, a comparison of the Domain Analysis exercises of Kuvi and Korku farmers reveal that each has developed their mixed cropping practices along different lines according to their distinct socio-economic and environmental circumstances.Nonetheless, problems with the application of Domain Analysis exercises result in this research not fully realizing the ideals of "participation". An analysis of these problems concludes that rapport, experience and the flexible use of participatory techniques are necessary to ensure optimal participation and the genuine elicitation of farmers' knowledge.ii Reproduced with permission of the copyright owner.
