Adoption of an integrated farming system (IFS) is essential to achieve food and nutritional security in small and marginal holdings. Assessment of IFS to know the resource availability and socio-economic condition of the farm household, farm typology plays a critical role. In this regard, a sample survey of 200 marginal households practicing mixed crop-livestock agriculture was conducted during 2018-2019 at Southern Coastal Plains, which occupies 19,344 ha in Thiruvananthapuram district, Kerala, India. Farming system typology using multivariate statistical techniques of principal component analysis and cluster analysis characterized the diverse farm households coexisting within distinct homogenous farm types. Farming system typology identified four distinct farm types viz. resource constrained type-1 households with small land owned, high abundance of poultry, very low on-farm income, constituted 46.5%; resource endowed type-2 households oriented around fruit and vegetable, plantation crop, with a moderate abundance of large ruminant and poultry, high on-farm income, constituted 12.5%; resource endowed type-3 household oriented around food grain, extensive use of farm machinery, with a moderate abundance of large ruminant, low on-farm income, constituted 21.5%; and resource endowed type-4 household oriented around fodder, with high abundance of large ruminant, medium on-farm income, constituted 19.5% of sampled households. Constraint analysis using constraint severity index assessed the severity of constraints in food grain, horticulture, livestock, complementary and supplementary enterprises in each farm type, which allowed targeted farming systems interventions to be envisaged to overcome soil health problems, crops and animal production constraints. Farming system typology together with constraint analysis are therefore suggested as a practical framework capable of identifying type-specific farm households for targeted farming systems interventions.
采用综合农业系统(IFS)对于实现小农户和边际农户的粮食和营养安全至关重要。评估 IFS 以了解农户的资源可用性和社会经济状况,农场类型学起着关键作用。在这方面,2018-2019 年在印度喀拉拉邦特里凡得琅区占地 19344 公顷的南部沿海平原,对 200 户从事混合作物-畜牧业的边际农户进行了抽样调查。利用主成分分析和聚类分析等多元统计技术的农业系统类型学,对不同的同质农场类型内共存的多样化农户进行了特征描述。农业系统类型学确定了四种不同的农场类型,即资源受限型 1 农户,拥有小块土地,家禽数量多,农场收入极低,占 46.5%;资源丰富型 2 农户以水果和蔬菜、种植园作物为导向,拥有大量大牲畜和家禽,农场收入较高,占 12.5%;资源丰富型 3 农户以粮食为主导,广泛使用农业机械,拥有大量大牲畜,农场收入较低,占 21.5%;资源丰富型 4 农户以饲料为主导,拥有大量大牲畜,农场收入中等,占抽样农户的 19.5%。利用约束严重指数对每个农场类型的粮食、园艺、畜牧业、补充和辅助企业的约束进行约束分析,从而可以设想有针对性的农业系统干预措施,以克服土壤健康问题、作物和动物生产约束。因此,农业系统类型学和约束分析建议作为一种实用框架,能够识别特定类型的农户,以便进行有针对性的农业系统干预。
