Food and Nutrition Security: What's the role of Agricultural Policy in Asia?
1. Food and Nutrition Security: What’s
the Role of Agricultural Policy in Asia?
Siem Reap, Cambodia; September 25-27, 2013
International Conference on “Agricultural Transformation in Asia: Policy Options for Food
and Nutrition Security”
H.E. Srun Darith (moderator); Dr. Akhter Ahmed,
Dr. Kamiljon Akramov, Dr. Olivier Ecker, Dr. Yanyan Liu
3. Motivation
Malnutrition slows economic growth (2-3% GDP lost) and deepens poverty
through productivity losses (10% of lifetimes earnings) from poor physical
performance and cognitive capacity as well as increased health care costs.
Poverty and malnutrition are closely associated and highly prevalent in rural
areas.
Although agricultural growth has been shown to have high poverty reduction
effects (Christiaensen et al. 2011; Diao et al. 2010; World Bank 2007), empirical
evidence on its nutrition impact is limited and inconclusive (Pinstrup-Anderson
2013; Berti et al. 2004; Masset et al. 2011).
Nonetheless, development and agricultural policy is often based on the
assumption that agricultural growth—particularly among smallholder
farmers—improves household food security and thereby reduces malnutrition.

7. Dietary Diversity as FNS Indicator
Dietary quality contributes to an individual’s nutrition and health status and
thereby to people’s economic productivity.
Households will only diversify their diets into higher-value micronutrient-rich
foods when they have satisfied their basic calorie needs. For the poor, these
foods are often unavailable or unaffordable.
Dietary diversity is a strong predictor of dietary quality in terms of
(micro)nutrient intake and adequacy (Ruel et al. 2013).
Household dietary diversity is strongly correlated with per capita calorie
consumption and dietary energy adequacy and is correlated with nutrition
outcome indicators such as anthropometrics (Ruel 2003; Ruel et al. 2013).
Dietary diversity is responsive to welfare trends and sensitive to shocks and
seasonality, indicating high inter-temporal validity (Headey & Ecker 2013).
Dietary diversity is measured as a count of different foods or food groups
consumed over a specified reference period.
All country cases studies use 12-scale or 16-scale household Dietary Diversity
Scores (DDS) as indicator of household food and nutrition security (FNS).

10. Motivation and Research Questions
Cambodia’s Rectangular Strategy (2009-2013) aims at achieving food and
nutrition security through agricultural transformation and growth (p. 13):
The first Strategic Rectangle to promote broad-based economic growth is the
“enhancement of the agricultural sector”, “especially in the high-potential
agricultural and agro-industrial sectors”.
“The agricultural policy of the Royal Government is to improve agricultural
productivity and diversification […] to bolster economic growth, create
employment and generate income in the rural areas, thus ensuring
nutritional improvement, food security and increased agricultural exports.”
This requires “shifting the direction from «expansionary» or «extensive»
agriculture to «deepening» or «intensive» agriculture, especially by
increasing the yields using the existing land through intensification”.
Does agricultural transformation and growth translate into improved food
and nutrition security (FNS)?
What are the policy-relevant variables enabling this transmission?

14. Measuring Agricultural Transformation
Agricultural transformation is characterized by at least four interlinked
developments:
1. Commercialization: From subsistence to market-oriented production
2. Intensification: Total factor productivity (TFP) growth
3. Specialization: Reduction of production diversity on profitable activities
4. Deagrarianization: Moving-out of agriculture
The effects of agricultural transformation on FNS are likely to substantially
differ across farm households, depending on their characteristics and stage in
the agricultural transformation process.
Household surveys provide variables indicating farmers’ stage in
transformation including the share of food sales on total food
production, agricultural income, agricultural production diversity, and the
share of off-farm income on total income.
15. Data and Methodology
Data: Cambodia Socio-Economic Survey (CSES) 2009
Methodology: Linear regressions to explore (cross-sectional) correlation between
agricultural transformation indicators and dietary diversity and child nutrition

19. Conclusions and Policy Implications
Economic growth is good but is not enough for reducing (child) malnutrition.
Agricultural transformation may slow down progress toward achieving food
and nutrition security, depending on the patterns of transformation and the
adaptation capacity of the food and nutrition insecure farm households.
Market expansion benefits FNS overall.
Farm households tend to be more food and nutrition secure than non-farm
households, while FNS—among subsistence farmers—increases with growing
non-farm income.
Subsistence farmers’ FNS increases with higher shares of food consumption
from purchases, whereas there is no evidence for positive effects from food
production diversification—but, from livestock diversification.
Unlike for FNS, there is no evidence for positive effects of agricultural
transformation on child nutrition.
To make agricultural transformation more nutrition-sensitive, complementary
nutrition-specific interventions are needed.
20. Tajikistan: Agricultural Biodiversity, Dietary
Diversity, and Nutritional Outcomes
Dr. Kamiljon T. Akramov
Coauthor: Mehrab Malek
Financial support: United States Agency for International Development (USAID)
21. Motivation
• Despite recent improvements, malnutrition in Tajikistan remains very
high: stunting among children under 5 is about 30%
• The current strategy of national government and development
partners is to promote agricultural growth and diversification to
ensure food security and nutritional outcomes
– Agrarian policy concept, Food Security Strategy and Agricultural Investment
Plan adopted by government in 2011
– USAID’s FFP and FTF programs and World Bank managed Global Agriculture
and Food Security Program
• These interventions could be very beneficial given the fact that
Tajikistan has less diversified agricultural production system
– About 75% of sown area is allocated to wheat and cotton
• However, there is little evidence regarding the linkages between
agricultural diversity, dietary diversity and nutrition in Central Asian
context
23. Research questions
• This study aims to provide empirical evidence on
agriculture-nutrition linkages in Tajikistan by investigating
three interrelated questions
– How is agricultural diversity associated with household dietary
diversity?
– Does allocation of more land to cotton and wheat affect dietary
diversity?
– How is dietary diversity correlated with nutritional outcomes?
• Assumption: Agricultural biodiversity influences nutritional
outcomes mainly by improving dietary diversity of
households and individuals
• What are the policy implications of main findings of the
study?
24. Measuring agricultural and dietary diversity
• Dietary diversity
– Count based household DD score was developed using
FAO’s (2011) guidelines (12 food groups)
– Calorie intake and food expenditure weighted Berry
indexes capture richness and evenness
– Calorie intake and food expenditure based Log-abundance
indexes captures richness and abundance
• Agricultural diversity
– Count based household level agricultural diversity score
– Land allocation based and population-weighted log
abundance diversity scores were calculated at the district
level
25. Data and Methodology
• Data sources
– Tajikistan Living Standards Survey (TLSS) 2007 and 2009
– District level population and land allocation data (Regions of Tajikistan
database, National Agency on Statistics, 2011)
• Methodology: Multilevel mixed effects and control function
models to examine relationships between agricultural
diversity and dietary diversity and nutritional outcomes
– Dependent variables: HH dietary diversity scores and child
stunting, measuring chronic malnutrition
– Key independent variables: agricultural diversity at HH and district levels
and share of cotton and wheat in total land area; HH dietary diversity
score, with a maximum of 12 food groups
– Control variables: child, HH and community characteristics, and region
fixed effects

28. Summary of Findings
• Key empirical results suggest that
– Agricultural diversity is positively associated with dietary diversity, and
– Dietary diversity is in turn correlated with child nutritional outcomes
and this relationship depends on child’s age
• Findings also suggest that there is a negative association
between household dietary diversity and share of land
allocation to cotton and wheat
• Households in communities located further away from urban
centers tend to have lower dietary diversity
• These results are robust
– Across alternative measures of household dietary diversity
– Changes in estimation techniques
– Controls for key child, household and community characteristics
29. Policy implications
• Further promotion of agricultural diversity may be
necessary by allocating more land to horticulture
and feed crops
– In some districts up to 85% of arable land is still
allocated to cotton and wheat
• Investment in infrastructure is important to
promote market integration across different regions
of the country
• Regional cooperation and trade is crucial to ensure
food and nutritional security in the country

40. Q3: Effect of Civil War on Nutrition
• Data:
– NLSS R1 (1995/96) and R2 (2002/03)
– Number of people killed by year and district
• Possible pathways through adverse effects on
– agricultural production
– agricultural assets (such as livestock)
– market and transportation infrastructure
41. Q3: Effect of Civil War on Nutrition
• Difference-in-difference (DID) method
controlling for ecological region-year specific
effects
• Findings: the effects of the civil war
– Total energy intake (no effect)
– % energy intake from cereals, roots, or tubers (+)
– % energy intake from eggs, milk, or meat (-)
– % energy intake from vegetable or fruits (-)
42. Pathways: Effect of Civil War on Nutrition
• Effects of civil war on
– Total expenditure p.c. (no effects)
– Total amount of livestock p.c. (no effects)
– Total income from crops (no effects)
• The pathway is not likely to be through the
effects on agricultural production or assets.
• Income elasticity on nutritional intake is lower in
more conflict-intensive areas, indicating that
markets being damaged may be the pathway.
43. Summary of findings
• Dietary diversity is positively associated with
livestock ownership and production of
vegetable and fruits
• Children’s length/height-for-age Z score and
weight-for-age Z score are positively
associated with household’s dietary diversity.
• The civil war decreased households’ dietary
diversity, likely through the disruption of the
markets.

Source: IFPRI 2011-12 Bangladesh Integrated Household Survey
50. Relative prices and diet quality
Real (inflation-adjusted) prices of rice has fallen by 36% over the past two
decades. This has helped the rural landless and the urban poor who
purchase the rice they consume
Despite a falling real price of rice, 17% of the population—about 27 million
ultra poor—remain seriously underfed
Therefore, the level of technology and institutional innovations that
made this price decline possible must be maintained
However, the real prices of some foods that are rich in micronutrients
(fruits, vegetables, pulses, animal sourced foods) are increasing
If policies are not undertaken to increase supply of non-cereal, nutrient-
rich foods, then their prices will continue to increase in the face of income
and population growth
Consequently, the diet quality and nutritional status of the poor are
likely to deteriorate further
52. Data and methodology
Data: Bangladesh Integrated Household Survey (BIHS)a nationally representative
household survey conducted by IFPRI in 2011-2012
Methodology
Instrumental variable regression to explore (cross-sectional) association
between dietary diversity and agricultural diversity
Dep. var: Household dietary diversity score (DDS) with a maximum of 12
food groups (calculated from a 7-day food consumption recall)
Indep. var.: Number of food crops grown (instrumented by soil types and
percentage of land irrigated), education, household size and demographic
composition, assets, electricity connection, rice price, location fixed
effects
OLS to explore association between food crop diversity and explanatory
variables
53. Agricultural diversity leads to dietary diversity
Found statistically significant positive association between production
diversity and dietary diversity
Other statistically significant factors influencing dietary diversity are:
Education of male hh head and female spouse (positive)
HH size (positive)
Electricity access (positive)
Farm size (positive)
Milk cow ownership (positive)
Hand tubewell ownership (positive)
Rice price (positive)
54. What factors affect crop diversity?
Crop diversity increases if:
Share of irrigated cropped area increases
Agricultural extension agents visit farm household
Household has access to loans
Household uses power tiller for land preparation
Crop diversity deceases if:
Household grows winter rice

Agricultural policy and diet quality
The solution to poor diet quality lies in balanced consumption of nutrient-rich
foods (fruits, vegetables, fish, meat, milk) which the poor desire but cannot
afford. Policies should be undertaken to:
Increase agricultural investments in non-staples that are high value added
and high nutrition value added
Reduce production and market risks associated with these crops
Support the bio-fortification of staple crops with micronutrients
Recent agricultural research initiatives by CGIAR centers – the Bio-
fortification Challenge Program HarvestPlus – and the Bangladesh Rice
Research Institute (BRRI) have shown that it is possible to get the
plants themselves to do the work of fortification. Zinc-enriched rice
was developed and released. Bio-fortification is cost-effective and
sustainable. Rice is an excellent vehicle for bio-fortification (with iron
and zinc) in the sense that the entire population eats it.
63. Take-Away Messages
We have opportunities and examples of success on how to bridge the
agriculture-nutrition divide
Our challenge AND opportunity is to work together - cross-sectorally (how?)
We need to do much better at documenting successes – and failures; we need
the evidence for advocacy, to stimulate investments

Can we empirically show the effects of agriculture on food security and nutrition? Absence of evidence of the impact of agriculture on nutrition outcomes doesn’t mean absence of impact!
Cambodia has a remarkable record in generating economic growth and in utilizing growth for reducing malnutrition until the mid-2000s.Since 2005, progress in reducing malnutrition has stagnated, despite continuing, high growth.Has the structure of growth been unfavorable for reducing malnutrition?Indeed, Cambodia’s economic growth has been narrowly based, largely on garments and tourism (and rendering the economy relatively vulnerable to external shocks).The Royal Government has recognized this problem and addressed it in the Rectangular Strategy (2009-2013), where agricultural growth is deemed a key role as a driver of broad-based and inclusive growth.
Agriculture is critical for achieving food and nutrition security in Cambodia:Agriculture adds up to about one-third of total GDP80 percent of the population lives in rural areas, and the vast majority is engaged in agriculture.Child underweight is much higher in rural areas (30.6 percent) than in urban areas (19.8 percent).Unlike in many other countries, the majority of the rural poor in Cambodia are net food SELLERS, and 70-80 percent of the poor live in good agricultural potential areas (WB 2007: 2008 WDR “Agriculture for Development”).Hence, agricultural transformation matters for a large share of the population and an even larger share of the malnourished people.Since the early 2000s, major agricultural activities in Cambodian upland have changed from mainly swidden and shifting cultivation of smallholders to large-scale economic land concessions and the restitution of already existing plantations.Substantial investments into modern agricultural production techniques as well as a conversion of subsistence farming methods into market-oriented crops have been transforming the land use systems. Other drivers of Cambodia’s agricultural growth and transformation include land reforms and productivity-enhancing policy incentives.
Use of regression approach (instead of pairwise correlation) to control for confounding effects. For example, we are interested in the effects of agricultural transformation, independent of the households’ wealth.HH DDS is calculated as monthly median count from a repeated 24-hour food consumption recall.HH expenditure is proxy for HH income.The proximity to farmer markets (and input markets) matters for ag. trans.Share of food consumption from purchases (as opposed to from own production) is a measure of ag. commercialization.Share of non-farm income is a measure of deagrarianization.Food crop diversity and livestock diversity are measures of agricultural production diversity or specialization. Food crop diversity and livestock diversity are the counts of different food crops and livestock types (for food production).
Survey sample observations (and proportions) [including households with complete data only]
Dietary diversity …Increases with household incomeDecreases with the distance to markets among all farmersIs higher among farmers than non-farmersIncreases with the share of non-farm income among subsistence farmersIncreases with growing food consumption from market purchases, or with declining consumption of own-produced foods, among subsistence farmers (which may be a bit surprising)Increases with the diversity of livestock holding (number of different livestock types) among all farmers, but no statistical effect for the diversity of cultivated crops
Unlike for dietary diversity, we find very few statistically significant effects of ag. trans. on child nutrition. And, the significant coefficients for the share of food consumption from purchases provide no clear picture.
Farmers adaptation capacity depends on their endowments which enables or disables them to benefit from the transformation process.In other words, we do not find that agricultural specialization compromise FNS or specifically dietary diversity. This finding may provide a rationale for improving FNS through agricultural transformation—particularly specialization—as intended by the Rectangular Strategy.As said before: Absence of evidence of the impact of agriculture on nutrition outcomes doesn’t mean absence of impact!Akhter Ahmed will present some evidence from Bangladesh on how to better integrate agriculture and nutrition and hence how to make agricultural growth more nutrition-sensitive.
