Nutrition Sensitive Agriculture Diversification And Dietary Diversity Panel Data Evidence From Tajikistan

Nutrition-sensitive agricultural diversification continues to receive interest among developing country stakeholders as a viable option for achieving dual goals of poverty reduction and food/nutrition security improvements. Assessing the effectiveness of this strategy is also essential in countries like Tajikistan. We attempt to enrich the evidence base in this regard. We assess the linkages between household-level agricultural diversification and dietary diversity (both household- and individual-levels) using unique panel samples of households and individual women of reproductive ages in the Khatlon province. Using difference-in-difference propensity-score methods and panel fixed-effects instrumental variable regressions, we show that higher agricultural diversification together with greater overall production per worker and land at the household level leads to higher dietary diversity, particularly in areas with poor food market access. Typology analyses and crop-specific analyses suggest that vegetables, fruits, legumes/nuts/seeds, dairy products and eggs are particularly important commodities for which a farmer’s own production contributes to dietary diversity improvement. Furthermore, decomposition exercises within the subsistence farming framework suggest that nutritional returns and costs of agricultural diversification vary across households, and expected nutritional returns may be partly driving the adoption of agricultural diversification. In other words, households’ decisions to diversify agriculture may be partly driven by potential nutritional benefits associated with enhanced direct on-farm access to diverse food items rather than farm income growth alone. Our findings underscore the importance of supporting household farm diversification in Tajikistan to support improved nutrition intake, especially among those living in remote areas. In a low-income setting with limited local employment opportunities that is vulnerable to a wide range of external shocks, this will likely continue to be one of the most straightforward and realistic paths to improving household’s nutrition resilience.

In Tajikistan, the poorest country in the Central Asia region and one of the poorest in the world, food consumption patterns remain inadequate for a significant share of the population. Undernutrition and child stunting, among other outcomes, remain prevalent. At the same time, overnutrition and obesity are becoming increasingly serious. Using pooled cross-section datasets collected in 2007 and 2015 from farm households in Khatlon province (the major agricultural area in Tajikistan), we investigate how key agricultural production practices (APPs) (household-level production diversification, land productivity, and production scale) are associated with household-level and individual-level nutritional outcomes, including dietary diversity and children’s and women’s anthropometric outcomes. We find that, in rural Khatlon, these APPs are positively associated with various nutritional outcomes at the household level. Furthermore, applying the methodologies of Lee (1979), Maddala (1983), and Björklund and Moffitt (1987), we find that a different set of factors affects the unobserved returns and costs of these APPs, which are heterogeneous across households, and that, importantly, adoption of these APPs is partly driven by the expected returns. However, despite the positive gross returns, diversifying farm production or raising land productivity is costly among small and resource-poor farms. Improving their access to land and agricultural capital, as well as improving overall land productivity, with particular support to women, may be critical for enhancing their nutritional outcomes by exploiting agriculture’s linkages to such outcomes.

Household-level agriculture-nutrition linkage (ANL) tends to be strong in a rural subsistence setting with limited access to the food market. In such a context, markets for food processing services also may be imperfect, and consequently a household’s time-investments in cooking may become important. Using the primary data in Tajikistan, we show that longer periods of time dedicated to cooking by women in the household often significantly enhance household-level ANL. Furthermore, an increase in the diversity, scale, and efficiency of household production, as well as longer cooking time, can also reduce intrahousehold inequality in nutritional outcomes among women and children. These effects are stronger in areas with lower nighttime light intensity and for households with lower values of cooking assets. In a context where household-level ANL is strong, ANL may also depend on households’ self-production of complementary inputs, including cooking services. This dependence reveals both unique opportunities for and vulnerabilities of ANL for the rural poor.

A growing number of governments, donor agencies, and development organizations are committed to supporting nutrition-sensitive agriculture (NSA) to achieve their development goals. Although consensus exists on pathways through which agriculture may influence nutrition-related outcomes, empirical evidence on agriculture’s contribution to nutrition and how it can be enhanced is still weak. This paper reviews recent empirical evidence (since 2014), including findings from impact evaluations of a variety of NSA programs using experimental designs as well as observational studies that document linkages between agriculture, women’s empowerment, and nutrition. It summarizes existing knowledge regarding not only impacts but also pathways, mechanisms, and contextual factors that affect where and how agriculture may improve nutrition outcomes. The paper concludes with reflections on implications for agricultural programs, policies, and investments, and highlights future research priorities.

New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

The State of Food Security and Nutrition in the World gives updates on the prevalence of undernourishment globally and the absolute number of undernourished, as well as the latest estimates for a number of global nutrition targets. This latest edition looks at the role of economic slowdowns and downturns in the rise of hunger and makes policy recommendations to safeguard food security and nutrition worldwide.

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.
