MOTIVATION
African (and other) food systems are changing rapidly
Big impacts on diets and nutrition
But our data (and to some extent our concepts) are inadequate to:Describe and track the relevant changes andLink them with confidence to nutrition outcomes
This situation needs to change, and can change
![Page 5: CHANGING FOOD SYSTEMS AND NUTRITION: DO WE HAVE THE CONCEPTSfoodsecuritypolicy.msu.edu/...FoodSystemsDietTransformation-GFS.pdf · CHANGING FOOD SYSTEMS AND NUTRITION: ... impact](https://reader031.vdocuments.mx/reader031/viewer/2022022600/5b3aaaf27f8b9a895a8baebc/html5/thumbnails/5.jpg)
THE SITUATION CAN BE CHANGED
Erratic, non-standardized national surveys è LSMS
LSMS è LSMS-ISA
We should be able to do something similar for diets and nutrition
Existing related effortsGlobal Dietary Database (GDD), FAO Global Individual Food consumption data Tool (GIFT), Tufts’ Indicators of Affordability of Nutritious Diets in Africa (IANDA), International Dietary Data Expansion Project (INDDEX)Anna Herforth to speak to these

ATTENTION IS BEING BROUGHT TO THE ISSUE
Global Nutrition Report’s “Nourishing the SDGs” (2017)“we must fill (data) gaps and change the way we analyse and use data”
The Global Panel’s “Metrics Brief” (2015) Improvement needed in six areas, among them food intake and food environment
Haddad and Webb in The Guardian (2015)Emphasize need for data on (a) food intake and (b) food environment metrics

FOOD ENVIRONMENT
The internal and external environment in which a consumer makes their decisions about food acquisition
and consumption

THIS SYMPOSIUM
Review what we know about changing food systems from farm to midstream to retail to diets
Highlight knowledge gaps and emerging issues
Review data efforts underway
Generate additional input on priorities for research - and for data generation and consolidation - to allow routine examination of changes in the food environment and its impact on food choices and nutritional outcomes

#1: DIETS ARE TRANSFORMING IN THREE WAYS
Food is becoming more purchasedAbout 50% in rural areas of Africa (by value)

perishableNon-cereals/pulses are 50% to 70% of diets in value terms

#1: DIETS ARE TRANSFORMING IN THREE WAYS
processed and preparedProcessed: 50% to 65% of all food; 70% to 80% of purchased foodFood away from home: exceeds 15% in some countries of ESA growing everywhere more rapidly than any other category

Upshots
(1) The post-farm segment of the agrifoodsystem is becoming ever more important
(2) Markets are now the dominant shaper of the food environment and thus of food choices

#3: URBAN DEMAND IS DRIVING THE TRANSFORMATION
Urban demand now over 50% of all food demand through markets in East and Southern AfricaThe least urbanized area of the continentUp to 70% and 80% elsewhereHuge agribusiness opportunitiesGrowth up to 8x over 30 years for some processed & perishable foods
Especially secondary and tertiary citiesAbout 60% of urban population, growing rapidly

#5: LOCAL DEMAND AND SUPPLY DOMINATE
About 90% of all food is from local production And reliance on imports is not systematically rising, even in Africa

The African food environment is increasingly characterized by
purposeful manipulation of the food environment by private sector
combined withabsent or dysfunctional public investment

#1: HOW ARE LOCAL SMES RESPONDING TO THE HUGE AGRIBUSINESS OPPORTUNITIES?What is the level, structure, and spatial distribution of the local agribusiness response?Major implications for level and location of employment Among Tanzanian millers: smallest 20% of grain millers employ 15x more labor per unit outputNext smallest employ 6x as many

#2: ARE THESE SMES BAD FOR FOOD SAFETY AND QUALITY?How does nutritional quality and food safety vary by:Imported vs. local products ?Firm size among locals?Some concerned that SMEs are a major problem for food safetyA conundrum: how to promote greater employment growth in agrifood system while safeguarding food quality and safety?

#3: HOW RAPIDLY ARE SUPERMARKETS TAKING OVER MARKET SHARE?Currently low in Africa and S Asia, higher in E and SE AsiaThe sector can grow very rapidly in total sales while growing very slowly in market shareContinuing role, for a long time, for the so-called traditional marketing system

We may be accustomed to thinking about the degradation of developing country diets as a
product only of FDI, and packaged foods

Traditional prepared foods, and traditional market outlets, can be major elements of this
problem

#5: HOW ARE AFRICAN FOOD ENVIRONMENTS CHANGING AND WHAT CAN BE DONE ABOUT IT?
Very little quantitative dataThis has to change in an ongoing way
Many helpful and potentially reasonable suggestionsGlobal Panel, HLPE, others
Most of which depend on public investment and regulationPoorest countries (already experiencing the nutrition transition) least able to do this

#5: HOW ARE AFRICAN FOOD ENVIRONMENTS CHANGING AND WHAT CAN BE DONE ABOUT IT? (2)
A strong expressed preference in Africa for local, healthy, even organic foodsa completely casual observation!
Some of the key suggestions are in a sense narrow interventions that can have broad effect, especially if they can leverage latent demand Mandatory labeling, public campaigns
Others are far more complex Improving the built environment, regulating trade

None of these “solutions” are easy
The battle is primarily in the political economy and in people’s minds, and needs to
be fought there
What lessons to take from Ghana, Brazil?
