Background and objectiveDiversified agricultural production is considered a means to enhance food diversity at the household level, particularly in developing countries where subsistence farming is common. Given the importance of a diversified diet for human health and the persistent malnutrition problem in Bangladesh, a pressing issue is how different crops and livestock production affect household food diversification, and this study sought to answer that question. MethodsUsing a multistage sampling procedure, data were collected from 190 small farm holder households from Hatiya (a coastal rural sub-district of Noakhali, Bangladesh). Farm production diversity (FPD) is measured using the household biodiversity index (HBI), a simple count of all crops and livestock produced on the farm. The household dietary diversity score (HDDS) is calculated, according to Food and Agriculture Organization (FAO) guidelines, by counting 12 food groups consumed by the households in the last 24 h preceding the survey. ResultsOn average, households consumed 6.49 food groups during the reference day, according to the household biodiversity index (HBI). The generalized Poisson log-linear regression results indicated that farm production diversity had a positive association with HDDS; one group of farm production increased the household dietary diversity (HDD) by 0.084 unit [β: 0.084, 95% CI: 0.064, 0.106; Exp (B): 1.087], an 8.7% increase in dietary diversity. Total land size, less time to reach the district market, and improved irrigation process affect dietary diversity in bivariate analysis. Farmer's reliance on production diversity reduces when the market is more accessible and improved irrigation is used for production. ConclusionSmallholder farm households in Bangladesh could benefit from context-specific, food-based nutrition-sensitive agriculture policies that focus on triangulation of diversified production, greater market access, and updated agricultural technology utilization.

Dietary diversity is the key to improved health and nutrition. Farm production diversity has the potential of enhancing dietary diversity but this interrelationship varies and is ambiguous in many societies. To examine the effect of farm production diversity on household dietary diversity using nationally representative panel data of Bangladesh we have used Bangladesh Integrated Household Survey (BIHS) data collected by International Food Policy Research Institute (IFPRI) in 2011/12, 2015 and 2018/19. Total sample size is 11,720. For assessing dietary diversity we have used different indicators namely household dietary diversity score (HDDS) and food variety score (FVS). We have also used multiple methods for measuring farm production diversity including production diversity score, crop diversity score and Simpson diversification index. Poisson regression model has been used. Results revealed a strong positive association among farm production diversity, income and dietary diversity though the extent of the association is small. The variables such as market orientation, access to market, age and education are also found to influence on household dietary diversity. Our results propose that for increasing dietary diversity efforts should be taken to increase farm production diversity combined with diverse income and market access.

The substantial existence of malnutrition globally, especially in developing countries, has usually driven policy initiatives to focus on improving household food security and nutrition primarily through prioritizing farm production diversity. Although indeed some empirical evidence has pointed to farm production diversity remedying malnutrition, other evidence has pointed to markets. Therefore, evidence is mixed and may be country or region variant. To contribute to closing such a gap in the literature, we used three waves of national panel survey data from Uganda and panel regression models to investigate associations between farm production diversity and dietary diversity, as well as impact pathways. We found that farm production diversity was positively and significantly associated with household dietary diversity. Farm production diversity influenced dietary diversity through own farm production, and market consumption food security pathways. The own farm production pathway showed a stronger associated impact. Increasing food expenditure by 1000 UGX via own farm production yielded an eight percentage point increment in household dietary diversity, while an equal expenditure via markets yielded a 5.3 percentage point increment. We also found existence of gender effects. Male headed households were associated with relatively poorer household dietary diversity. These findings could have broader implications for countries practicing smallholder agriculture.

The association between farm production diversity and dietary diversity in rural smallholder households was recently analysed. Most existing studies build on household-level dietary diversity indicators calculated from 7d food consumption recalls. Herein, this association is revisited with individual-level 24 h recall data. The robustness of the results is tested by comparing household- and individual-level estimates. The role of other factors that may influence dietary diversity, such as market access and agricultural technology, is also analysed. A survey of smallholder farm households was carried out in Malawi in 2014. Dietary diversity scores are calculated from 24 h recall data. Production diversity scores are calculated from farm production data covering a period of 12 months. Individual- and household-level regression models are developed and estimated. Data were collected in sixteen districts of central and southern Malawi. Smallholder farm households (n 408), young children (n 519) and mothers (n 408). Farm production diversity is positively associated with dietary diversity. However, the estimated effects are small. Access to markets for buying food and selling farm produce and use of chemical fertilizers are shown to be more important for dietary diversity than diverse farm production. Results with household- and individual-level dietary data are very similar. Further increasing production diversity may not be the most effective strategy to improve diets in smallholder farm households. Improving access to markets, productivity-enhancing inputs and technologies seems to be more promising.

BackgroundNutrition education is crucial for improved nutrition outcomes. However, there are no studies to the best of our knowledge that have jointly analysed the roles of nutrition education, farm production diversity and commercialization on household, women and child dietary diversity.ObjectiveThis article jointly analyses the role of nutrition education, farm production diversity and commercialization on household, women and children dietary diversity in Zimbabwe. In addition, we analyze separately the roles of crop and livestock diversity and individual agricultural practices on dietary diversity.DesignData were collected from 2,815 households randomly selected in eight districts. Negative binomial regression was used for model estimations.ResultsNutrition education increased household, women, and child dietary diversity by 3, 9 and 24%, respectively. Farm production diversity had a strong and positive association with household and women dietary diversity. Crop diversification led to a 4 and 5% increase in household and women dietary diversity, respectively. Furthermore, livestock diversification and market participation were positively associated with household, women, and children dietary diversity. The cultivation of pulses and fruits increased household, women, and children dietary diversity. Vegetable production and goat rearing increased household and women dietary diversity.ConclusionsNutrition education and improving access to markets are promising strategies to improve dietary diversity at both household and individual level. Results demonstrate the value of promoting nutrition education; farm production diversity; small livestock; pulses, vegetables and fruits; crop-livestock integration; and market access for improved nutrition.

The persistence of malnutrition resulting from micronutrient deficiencies in developing countries has led to a recent movement for better linkages between agriculture extension and nutrition education in development work. Few empirical studies have examined this link, and previous studies in the agricultural development literature have primarily focused on the link between nutrition and farm diversity, productivity and profitability. Smallholder farmers are often faced with the decision to consume or sell farm products. These joint production and consumption decisions impact household nutrition and dietary diversity. Furthermore, the farmer’s decision may be driven by access to markets for selling products produced by the household or for purchasing food for home consumption. Using primary data from a household-level survey in Bangladesh, this study investigates the effect of agricultural production and market participation on food group consumption. The data was collected from over 1,000 households from two districts in Bangladesh from August to November. The empirical analysis models consumption of various food groups as a function of farm production diversity, access to markets, household income and household characteristics such as age, gender and education of the household head.

Agriculture has the potential to improve dietary diversity through farm production diversity if farming households consume what they produce. However, the linkages between a household’s own agricultural production and dietary diversity are not well understood. This study uses a count of crop species, animal species, production diversity score, and the Simpson’s index as measures of farm production diversity to assess the effect of production diversity on the dietary diversity of households, women and children. A Poison model was employed on a sample of 779 farming households selected using a multistage sampling technique in a household survey representative at the County level in Kisii and Nyamira Counties, Kenya. The findings of the study indicate that farm production diversity is significantly associated with the dietary diversity of women and that of the entire household, but is not associated with the dietary diversity of children. The count of the animal species has the highest magnitude of association with dietery diversity in this study. Every additional animal species kept leads to a 0.33 and 0.13 increase in household dietery diversity and the dietery diversity of women respectively. Children’s dietary diversity is significantly associated with the education of the mother, household size and age of the child. The study highlights the need to consider individual dietary requirements when developing nutrition interventions and policy, as opposed to general dietary interventions targeting the entire household.

Farm production diversity has the potential to influence the diversity of household diets, an important nutrition outcome associated with the nutrient adequacy of diets and the nutritional status of individuals. Yet, little empirical research has assessed the relationship between farm diversity and diet diversity or the plausible causal mechanisms that may operate between these two constructs. This research examines cross-sectional data from the Malawi Third Integrated Household Survey (IHS3), a nationally representative sample of farming households in Malawi, implemented from March 2010–March 2011 as part of the World Bank Living Standards Measurement Study – Integrated Surveys on Agriculture (LSMS-ISA). These data were used to determine the relationship between farm production diversity and household dietary diversity, and to identify determinants of this relationship. Two indicators of dietary diversity, a modified Household Dietary Diversity Score (HDDS), and the Food Consumption Score (FCS), were calculated along with three indicators of farm production diversity including the Simpson’s Index, a metric accounting for both species richness and evenness. In multiple regression analyses, adjusting standard errors for the complex survey design of the IHS3 and controlling for the effects of several covariates on household dietary diversity, farm production diversity was consistently positively associated with dietary diversity (P<0.0001). The association of increased farm diversity as measured by a combined crop and livestock measure on dietary diversity was significantly greater in woman-headed households compared to those headed by men (HDDS: P=0.008; FCS: P=0.076). The positive association of farm diversity with dietary diversity was also greater in wealthier households (P<0.05). Consumption of legumes, vegetables and fruits was especially strongly associated with greater farm diversity. More diverse production systems may contribute to more diverse household diets. However, this relationship is complex; it may be influenced by gender, wealth, control of household decisions, the relative market-orientation of a household’s agricultural production, and the specific nature of farm diversity.

Improved food security and nutrition remain a notable global challenge. Yet, food security and nutrition are areas of strategic importance regarding the United Nations' Sustainable Development Goals. The increasingly weakening global food production systems pose a threat to sustainable improved food security and nutrition. Consequently, a significant population remains chronically hungry and severely malnourished. As a remedy, farm production diversity (FPD) remains a viable pathway through which household nutrition can be improved. However, evidence is mixed, or unavailable on how FPD is associated with key nutrition indicators like household dietary diversity, energy, iron, zinc, and vitamin A (micronutrients). We use the Uganda National Panel Survey (UNPS) data for rural households to analyze differential associations of sub-components of FPD on dietary diversity, energy, and micronutrient intake. Panel data models reveal that indeed crop species count, and animal species count (sub-components of FPD) are differently associated with household dietary diversity score (HDDS), energy, and vitamin A sourced from markets. Moreover, when volumes of these nutrition outcomes were disaggregated by source (own farm vs. markets), the animal species count was only positively significantly associated with nutrition outcomes sourced from consumption of produce from own farm. Associations were insignificant for nutrition indicators sourced from markets except vitamin A. The crop species count, however, consistently showed a strong positive and significant association with energy, and all studied micronutrients sourced from own farm produce consumption, as well as those sourced from markets except Vitamin A, which was negative but insignificant. Therefore, inclusive, pro-poor, and pro-nutrition rural policy initiatives in the context of rural Uganda and similar ones, could more widely improve household nutrition through prioritizing crop species diversification on own farms because crops fetch wider nutrition gains.

Improved access to markets can influence household dietary diversity, consumption expenditure, and food security through multiple pathways. Market access can increase smallholder farmers’ income through decreased transaction costs, improve diet quality, and reduce poverty and household food insecurity. Improved market access also expands the variety of food available, opening opportunities for consumption diversification. We examine the association between market access and household dietary diversity, consumption expenditure, and food security in the Eastern African countries of Ethiopia and Tanzania using nationally representative panel data from the World Bank’s Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA). The empirical findings demonstrate that households located closer to market centers spend more on total household consumption expenditure, consume more diverse diets, and are less food insecure than households located farther away from markets. The results suggest that investing in accessible market development and rural infrastructure to link smallholder farmers to markets is essential for improving household dietary diversity and food security in sub-Saharan African countries.
