While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own‐produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own‐produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition‐sensitive."],["dc.identifier.doi","10.1111/1477-9552.12359"],["dc.identifier.eissn","1477-9552"],["dc.identifier.issn","0021-857X"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16771"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/76135"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.notes.intern","Merged from goescholar"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.rights","CC BY-NC-ND 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/4.0"],["dc.title","Agricultural Commercialisation and Nutrition in Smallholder Farm Households"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

However, potato yields continue to remain very low in these regions mainly due to use of poor quality seed. The recent development of rapid seed multiplication technique has helped to shorten the duration of certified seed potato (CSP) production and increase the supply of seed. This study assessed the effect of using CSP on yield, input use, and food security among smallholder farmers. It focused on potato growers in central highlands of Kenya, who were in close proximity to a private seed multiplier that uses these new techniques. The study used the propensity score matching technique and data collected from 408 smallholder farmers through personal interviews. The farmers were stratified by use of CSP. Results: The study found positive effect of using certified seed on both yield and food security. There was also a slight increase in input usage, apparently due to pursuit by farmers to optimize the gains from CSP. Conclusion: The study concludes that using CSP has positive effect on smallholder farm households."],["dc.identifier.doi","10.1186/s40066-017-0101-0"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16315"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62236"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","2048-7010"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Productivity and food security effects of using of certified seed potato: the case of Kenya’s potato farmers"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Yet potato is major food staple and source of income to the predominantly smallholder growing households in the tropical highlands of this region. A major cause of the low potato yields is the use of poor quality seed potato. This paper examines the factors determining the decision to use certified seed potato (CSP), as well as the intensity of its use, among potato growers with access to it. We focused on potato growers in the central highlands of Kenya and used regression analysis to test hypotheses relating to potential impediments of CSP use. The study found that the distance to the market (a proxy for transaction costs), household food insecurity, and asset endowment affect the decision to use CSP. However, the effect of the intensity of use of CSP depends on how the intensity variable is defined. Several other control variables also affect the decision and extent of CSP use. The study concludes that transaction costs, asset endowment, and household food insecurity play a major role in the decision by smallholder potato farmers to use CSP and the extent to which they do so. We also discuss the policy implications of the findings."],["dc.identifier.doi","10.3390/agriculture6040055"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16316"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62237"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.issn","2077-0472"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Determinants of the Use of Certified Seed Potato among Smallholder Farmers: The Case of Potato Growers in Central and Eastern Kenya"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Many of the world's poor are smallholder farmers. Agricultural commercialization - meaning a shift from subsistence to more market-oriented farming - can play a central role in improving smallholder welfare. Previous studies evaluated the impact of agricultural commercialization on income poverty, but whether income gains from commercialization are really used for satisfying basic needs was hardly analyzed up till now. Here, we evaluate the effect of commercialization on income poverty, as well as on the multidimensional poverty index that looks at deprivations in terms of education, nutrition, health, and other dimensions of living standard. Using data from 805 farm households in Kenya, we estimate average treatment effects and also analyze impact heterogeneity with quantile regressions. Results show that commercialization reduces both income poverty and multidimensional poverty. The magnitude of the income gains is positively correlated with income level, meaning that market-linkage support for marginalized farms may be needed to avoid rising inequality. However, the effect in terms of reducing basic needs deprivations is stronger for the poorest households, suggesting that agricultural commercialization contributes effectively to achieving the sustainable development goals."],["dc.identifier.doi","10.1016/j.worlddev.2018.10.012"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62235"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0305-750X"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.title","Commercialization of the small farm sector and multidimensional poverty"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
