註釋 The theoretical resources drawn upon for this research include the concept of socio-technical system, agriculture as performance, and the culture of task groups. Together these concepts help to understand rice farming as a collective and mutually shaping social and technical performance rather than the activity of an individual farmer. The thesis shows how existing and new rice farming practices and task groups are reconfigured through socio-technical innovations within a given agro-ecological setting. SRI acted as a catalyst, initiating a process of readjustments in the socio-technical configurations of rice farming, varying according to the local context. Farm households, while incorporating SRI into the existing farming system, try to seek complementarity and synergy between various rice farming methods. This allows fluidity among task groups and leads to the extension and diversification of the repertoire of methods used, taking into account the dynamics of the larger socio-economic conditions. The thesis highlights farmers adaptive capacities to reconfigure practices, reorganize social formations, and reschedule routines in response to farming interventions, in order to maximize the exploitation of agro-ecological niches, minimize uncertainty in farm production and rationalize the employment of the available work force.
