The persistent use of traditional farming practices and cultivation of low yielding variety of crops on scattered small farmland holdings by agrarian farming households in Nigeria has put pressure on land and water resources, consequently leading to depletion of soil productivity with spill-over effects on the environment, crop-output and farm-income. Addressing this requires a holistic approach, especially in light of farmers’ apathy towards transitioning from traditional farming practices to more sustainable ones, and motivated this research. This research used cross-sectional survey data obtained from 350 farmers randomly chosen from South-West Nigeria. This study applied a descriptive statistical technique to present the mean statistics of sampled farmers’ characteristics. Similarly, the study applied a bivariate probit model to examine the influences on farmers’ decisions about conservation agriculture (CA) adoption, as well as to isolate the factors driving farmers’ choices on acquisition of information decision and the use of CA practices. The results revealed that decisions to acquire information and adopt CA were jointly determined by farmers, owing to the positive and strong correlation parameter-rho in the estimated model. More so, the post-estimation Murphy test score apparently revealed no significant departure from the normal and jointly distributed error terms.

Purpose Many nations in Sub-Saharan Africa, including Nigeria have initiated programmes targeted at addressing food insecurity, but without any major significant breakthrough. This necessitates the call for inclusion of social network institutional framework into the food and nutrition security policy of many developing countries. This is touted as an important social safety net needed for farming households’ economic advancement and welfare. Consequent on this, the purpose of this paper is to investigate the importance of social networks in building resilience against food insecurity among farmers in Oyo State, Nigeria. Design/methodology/approach Data collected from a sample of 297 smallholder farmers during 2015/2016 agricultural production season were analysed using descriptive statistics to describe farmers’ notable characteristics. However, Foster–Greer–Thorbecke indices vis-à-vis food consumption expenditure-metrics technique was used to evaluate the food security profile of the respondents. Similarly, ordinary least square and two-stage least square (2SLS) models were applied to investigate the effects and “reverse causality” in the social networks food security model. Findings The study findings indicated that about 48.15 per cent of the smallholder farmers are food insecure. Similarly, the study revealed that age (ppppppp Social implications There is an urgent need for pragmatic policies that support systematic and organized social groups and networks formation in the rural/agrarian areas across Nigeria. Originality/value A widely accepted view of economic theory posits that traditional capitals (physical, economic/financial and human) drive households’ welfare including food security status. However, this study has established the relevance of social networks as an important component of human well-being. Apparently, this study also established the exogeneity of social networks in the framework of households’ food security status.

Enhancing sustainable food security requires agricultural production systems to change in the direction of higher productivity and to mitigate lower output variability in the face of climate extreme related hazards such as land degradation. Adoption of resilient food production system capable of withstanding disruptive events is therefore needed to stabilize farmers’ productivity. Consequently, participation in collective actions has been touted as an effective approach to enhance cooperation among individuals within a social system and to advance adoption of climate-smart farming techniques (conservation agriculture). This study investigated this perspective using heterogeneous treatment effects estimation to analyze the data collected from 350 smallholder farmers selected randomly from the South–West Nigeria. The average treatment effects on the treated estimate revealed that participation in collective actions had adoption-increasing effect for each unit variation in propensity score rank, although, negative selection effect was suspected. Similarly, information acquisition, access to extension service and frequency of visit by extension workers are significant features that predict adoption in the study area. However, rosenbaum sensitivity analysis test revealed that the increasing effect of participation in collective actions on conservation agriculture adoption is insensitive to unobserved bias that may double or triple the odds of exposure to treatment. Hence, the average treatment effect on the treated estimate is a pure impact of the participation in collective actions. The study concluded that farmers with high propensity to participate in collective action have high likelihood to adopt climate-resilient farming practices compared to the counterparts with a lower propensity of participation in collective action.

The major concern of most African countries, including Nigeria, in recent times is how to increase food production because of food insecurity issues, which by extension, is a major contributing factor to the prevalence of poverty. Therefore, adoption of conservation agricultural practices is regarded as a pathway to drive the achievement of food and nutrition security, as well as the needed optimal performance in the agri-food sector. Reportedly, scaling up of the limited adoption of these practices could be facilitated through kinship ties, peer influence, and social networks that govern mutual interactions among individuals; therefore, this motivated the study. Using cross-sectional data obtained from 350 sample units selected from South-Western Nigeria through a multistage sampling technique, this study applied descriptive statistical tools and cross-tabulation techniques to profile the sampled subjects while count outcome models were used to investigate the factors driving counts of conservative agriculture (CA) adoption. Similarly, a marginal treatment effects (MTEs) model (parametric approach) using local IV estimator was applied to examine the effects of CA adoption on the outcome (log of farmers’ farm income). Additionally, appropriate measures of fit tests statistics were used to test the reliabilities of the fitted models. Findings revealed that farmers’ years of farming experience (p < 0.1), frequency of extension visits (p < 0.05), and social capital viz-a-viz density of social group memberships (p < 0.05) significantly determined the count of CA practices adopted with varying degrees by smallholder farmers. Although, social capital expressed in terms of membership of occupational group and diversity of social group members also had a positive influence on the count of CA practices adopted but not significant owing largely to the “information gaps” about agricultural technologies in the study area. However, the statistical tests of the MTEs indicated that the treatment effects differed significantly across the covariates and it also varied significantly with unobserved heterogeneity. The policy relevant treatment effect estimates also revealed that different policy scenarios could increase or decrease CA adoption, depending on which individuals it induces to attract the expected spread and exposure.
