Abstract

Due to complexity of smallholder farms, many times technologies with great potential fail to achieve the desired impact in leveraging productivity and profitability of the farming community. In the Indo-Gangetic Plains there is an urgent need to understand the diversity of farm households, identifying the main drivers deciding their system thus, classifying them into homogenous groups. In the present study, the diversity of smallholder farms was assessed using crop, livestock and income related characteristics and associated farm mechanization. Using principal component analysis and cluster analysis for 252 farm households, 4 farm types were identified i.e. Type 1. Small Farm households with cereal-based cropping system and subsistence livestock (39%), Type 2. Small Farm households with diversified cropping system dominated by cereal and fodder crops with only cattle herd (9%), Type 3. Marginal Farm household with diversified cropping system dominated by cash crop and herd comprising of only cattle (39%), Type 4. Marginal Farm household with diversified cropping system dominated by cereal crops and herd dominated by small ruminants (12%). Based on the constraints identified for different components of farming systems, low-cost interventions were planned for each farm type. These interventions have resulted in 84.8-103.2 per cent increase in the income of the farm HH under study suggesting usefulness of typology-based intervention planning in increasing income of small farm holders.

摘要

由于小农农场的复杂性,许多具有巨大潜力的技术未能实现提高农业社区生产力和盈利能力的预期效果。在印度-恒河平原,迫切需要了解农户的多样性,确定决定其系统的主要驱动因素,从而将他们分类为同质群体。在本研究中,使用与作物、牲畜和收入相关的特征以及相关的农业机械化来评估小农户的多样性。对 252 个农户进行主成分分析和聚类分析,确定了 4 种农场类型,即:1. 以谷物为基础的种植系统和自给性牲畜为主的小型农户(39%);2. 以谷物和饲料作物为主、仅有牛群的多样化种植系统的小型农户(9%);3. 以现金作物和仅包括牛的畜群为主的边缘农户(39%);4. 以谷物作物为主、以小反刍动物为主的多样化种植系统和畜群的边缘农户(12%)。根据对农业系统不同组成部分确定的限制因素,为每个农场类型制定了低成本干预措施。这些干预措施使研究中的农场 HH 的收入增加了 84.8-103.2%,这表明基于类型学的干预规划在增加小农户收入方面是有用的。
