Farming system农作制度 The farming system is defined as a unique and reasonably stable arrangement of farming enterprises that the household manages according to well defined practices in response to physical, biological and socio-economic environments and in accordance with the households goals, preferences and resources. These factors combine to influence the output and production methods (Shaner(1982)in Merrill-Sands, 1986) 是农户按照其基于物理、生物和社会-经济环境而精 心设计的生产措施,与其目的、优先选择和资源状况协 调一致的对农业生产的独特的、相对稳定的安排

Understand complexity of small holder farming A farming system is more than just the production of crops and rearing of animals. It includes other resources, the activities and inputs of all members of the household. Therefore, farming systems anal ysis must helps us understand how rural households use all their natural resources to make a living. Farming systems analysis includes collecting fuel wood, building materials and other biological products, e.g. traditional medicine .lt also includes non-farm activities like basket weaving or brick making, and offfarm activities like wood collecting and labouring. In the past, the interactions between farm enterprises, and between on-farm and off-farm activities were ignored. Farming systems analysis looks at all enterprises all species cultured or captured and all agroecological niches utilized by the household regardless of resource access regime .In doing this it recognises that farm households do a lot more than grow crops and tend animals!
