Abstract

This study analyzes the spontaneous impact of human, social and natural capital on food crop technical efficiency (TE) in Sub-Saharan Africa (SSA). Our study contributes to the literature by adopting the meta-analysis method to investigate the relationship between TE and the three groups of capitals to better shed light on the TE in SSA regions. Our results highlight that social capital is the most critical factor among the three groups of capitals in promoting farming productivity. In particular, agriculture efficiency benefits from increasing people's trust in institutions and the frequency of extension visits. Natural capital like temperature and elevation is essential in determining the farming TE in SSA regions. Outstandingly, our results also indicate that calorie intake, a proxy of labor quality, should be improved to achieve better productivity.
