The programme in Malawi – the Farm Input Subsidy Programme (FISP) – includes legume seeds, but little research has been undertaken to evaluate the effects of this strategy on household dietary diversity. In this study, we used two waves of integrated household panel survey data of 2013 and 2016 to examine the dietary diversity gains from inclusion of legume seed coupons in the programme. The control function approach for dealing with selection bias into a programme is used in Poisson regression of panel data. The results show that access as well as redemption of legume coupons is positively associated with diversified diets. This is especially through location fixed effects in the southern region of Malawi, higher production diversity, greater land holding sizes and the sale of maize. Further, households that had less need to satisfy hunger through the growing of maize were those likely to redeem legume coupons. The results suggest a more nuanced pathway of impact from coupon access, redemption or type of crop produced to dietary diversity than the pathway that might be expected, and have implications for how best to understand and conceptualise the tensions and synergies between addressing different aspects of malnutrition in all its forms – and suggest the importance of addressing food insecurity constraints that potentially limit the growing of nutrient-rich legume crops as well as wider increases to dietary diversity. The results also point to the importance of the income pathway and food markets in facilitating greater dietary diversity. Further consideration of these issues by policymakers and the wider agri-nutrition community will be important to advance the discussion and research of how best to design AISP and other public policy to address malnutrition in all its forms.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"113 ","pages":"Article 102309"},"PeriodicalIF":6.5,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3398538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using LSMS-ISA survey data for Uganda, this paper examines the channels through which household nutrient intake is influenced under crop commercialization. A control function was employed to address issues of endogeneity, while the Generalized Propensity Score technique was used to estimate the continuous treatment effects. The results show that commercialization mainly affects nutrient intake through the resulting crop income. From a gender perspective, the findings show that female control of farm income positively and significantly affects the overall nutrient intake. The findings point to three important implications. First, interventions geared towards agricultural commercialization are beneficial to household nutrition via income generation. Given this income-nutrition linkage, proactive steps towards support for nutrition-sensitive commercial agriculture are needed to ensure that nutrient-rich foods are available on the market. Second, there is the need to improve knowledge and perception of what constitutes a good diet. This would provide a stronger linkage between agricultural production, income, and nutrition. Third, gender relations in a household are critical for nutrition outcomes. As such, measures which can empower women to own and control key agricultural production assets are needed to reinforce the link between commercialization and nutrition.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"113 ","pages":"Article 102328"},"PeriodicalIF":6.5,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1704568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experience-based measures of food security capture the diversity of diets, food shortage, and other aspects of food security, including psychological and behavioral manifestations of insecure food access. In Nigeria, the agricultural sector contributed about 22.35% to the nation's gross domestic product during 2021. In addition, almost 70% of Nigerians engage in farming for subsistence purposes, with climate change and poor irrigation systems affecting their agricultural productivity. Consistent with previous work linking higher agricultural productivity with better welfare outcomes among Nigerian households, we find that an increase in agricultural productivity increases food security as measured by experience-based indicators. Specifically, a 10% growth in agricultural productivity decreases the likelihood of (i) relying on less preferred foods, (ii) limiting the variety of food eaten, and (iii) limiting portion size at mealtimes by 3.7%, 3.9%, and 1.9%, respectively.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"113 ","pages":"Article 102286"},"PeriodicalIF":6.5,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1828037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We identify the cost of meeting nutrient requirements for whole households in rural Malawi from and the nutrient-level drivers thereof. From 2013 to 2017, we can identify a household least-cost diet only 60% of the time with an average cost of $2.32/person/day (2011 US$ PPP). We illustrate that larger households have more diverse nutrient needs and face a higher cost for 1000 calories of a sufficiently nutrient dense diet. Shadow price analysis shows riboflavin to be the costliest nutrient in the market. We use policy scenarios to understand what drives the infeasibility and high cost. Simulating the impact of selenium soil biofortification of maize results in a feasible diet 94% of the time at half the cost ($1.22/person/day on average) and eliminates the shadow price of copper. This is explained by insufficient selenium from sources low in copper such that under baseline conditions it is impossible to get enough selenium without too much copper. Even when feasible, to avoid copper, more higher cost foods enter the diet than would be otherwise needed to meet remaining nutrient requirements. Other value chain scenarios to increase the availability and lower the cost of nutrient-dense foods did not meaningfully change the diet cost results. Of direct relevance to Malawi, this study demonstrates more broadly how least-cost diet methods can be used to assess barriers to accessing an adequate diet and the potential impacts of policy options.</p></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"113 ","pages":"Article 102275"},"PeriodicalIF":6.5,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9763653/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3207285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contributes to the literature by assessing those linkages across different income groups. The study finds that agriculture commercialisation has a significant effect on dietary diversity for the lower-income group; but not for the whole sample. Education levels of the head of household and of the highly educated female member, overall income levels and area of land cultivated have positive and significant effects on dietary diversity; whereas age of the head has negative and significant effect. It also finds that agriculture commercialisation and household dietary diversity both have an insignificant effect on child stunting, wasting, and underweight even for the lower-income group.
