This study investigated the impact of social capital on farm productivity and food security among cocoa-based farming households in Southwestern, Nigeria. A multistage sampling procedure was employed to select 300 cocoa-based farming households for the study. Two-step Heckman and three-stage simultaneous models were used for the analyses. The results of a two-step Heckman model revealed that asset, age of household head, years of education, gender, farm size, land tenure, loan interest rate and extension visits were the determining factors influencing the probability of participating in social groups. While the level of participation in the social groups were determined by age of household head, years of education, membership in agricultural organization, off farm income, land tenure, interest rate, distance to credit sources, extension visit, decision making index, cash contribution index, and labour contribution index. The simultaneous equation models showed that social capital was positive and significantly influenced farm productivity and food security of the cocoa-based farming households. A unit increase in the instrumented social capital increased the household's farm productivity and food security by 0.577 kg/₦ and 0.861 calories, respectively. The study concluded that social capital enhanced farm productivity and improved food security of the cocoa-based farming households. The study therefore, recommends that rural credit should be given to cocoa farming households based on their social collateral. This would enhance cocoa farming households' access to productive resource and thus achieve financial leverage that would further boost farm productivity. Enhanced farm productivity would improve their food security status.
本研究调查了社会资本对尼日利亚西南部以可可种植为主的农户的农场生产力和粮食安全的影响。采用多阶段抽样程序选取了300户以可可种植为主的农户进行研究。分析使用了两步Heckman模型和三阶段联立模型。两步Heckman模型的结果显示,资产、户主年龄、受教育年限、性别、农场规模、土地保有权、贷款利率和推广访问是影响参与社会群体概率的决定因素。而参与社会群体的程度则由户主年龄、受教育年限、农业组织成员身份、非农业收入、土地保有权、利率、到信贷来源的距离、推广访问、决策指数、现金贡献指数和劳动力贡献指数决定。联立方程模型表明,社会资本呈正向且对以可可种植为主的农户的农场生产力和粮食安全有显著影响。工具化社会资本每增加一个单位,家庭农场生产力和粮食安全分别提高0.577千克/奈拉和0.861卡路里。研究得出结论,社会资本提高了以可可种植为主的农户的农场生产力并改善了粮食安全。因此,该研究建议应根据可可种植农户的社会抵押物向其提供农村信贷。这将增强可可种植农户获取生产资源的机会,从而实现金融杠杆作用,进一步提高农场生产力。提高农场生产力将改善他们的粮食安全状况。
