Contribution of small‐scale farmers to global food security: a meta‐analysis

Abstract

In this study, the impacts of small‐scale farmers on food security enhancement were estimated in three dimensions of food availability, food access and food utilization. In the current study, a systematic review and meta‐analysis have been performed to synthesize results from 75 original articles. It includes the pooling of data that quantitatively investigate whether or not causal links characterized in the original articles remain valid across a broader scope of the literature. The findings show that farmers who are small‐scale in natural/physical capital would lead to higher median food production and agricultural productivity, compared with small‐scale farmers in financial capital, at about 19% and 15%, respectively. Meta‐regression results indicate that small‐scale farmers in natural/physical capital have significantly positive effects on the average agricultural productivity, food income and biofortification. By contrast, farmers who are small‐scale in financial capital have negative effects on food security. The influential role of these small‐scale farmers should also be considered since food insecurity leads to socio‐economic implications. Therefore, it is recommended to cultivate higher value crops, to participate in various income‐generating activities such as fisheries and forestry, and to pay agricultural credits. The effect of the size of small‐scale farmers on global food security is very useful for policymakers to plan for a world without hunger. © 2022 Society of Chemical Industry.

Effective Economic Model for Greenhouse Facilities Management and Digitalization

“…Moreover, higher yields (H9) and lower production costs (H10) directly cascaded into greater profitability, as expected. However, examinations of costyield tradeoffs are needed given budget constraints facing regional and remote greenhouse operators [69]. In addition, online coordination platforms can support procurement optimization if usability barriers are addressed through customer-centric design [70].…”

“…In the same vein, Azadi et al [46] show that small-scale farmers have significant positive effects on average agricultural productivity, food income, and biofortification. In contrast, farmers with small-scale financial capital generate negative effects on food security.…”

Food Security and Women Case Study of Mahu Country on Saparua Island

“…In a broad sense, the real role of women in supporting the family economy has been going on since the emergence of the family institution itself. The division of tasks between members in the family, including for women, is basically an economic activity (Azadi et al, 2022). The involvement of women in earning a living is also influenced by their socio-cultural background which has institutions that regulate their supporting community members including women's behavior, household economy and natural environmental conditions which also influence the pattern of household livelihoods (Soemarsono et al, 1995. To help their husbands earn money for the household, the women in Mahu bake sago, bread, sell at huts/kiosks, sew roofs, sell food/drinks and sew clothes, which are a series of economic activities.…”
