Dr. Johan Swinnen - Director General, International Food Policy Research Institute (IFPRI).
4 March 2020. Brussels. DevCo Infopoint. This presentation discussed the role of trade and global value chains in sustainable food systems and the role that private standards and public regulations play in this process, drawing on a variety of empirical indicators and studies.

Trade is key for sustainable
food security and nutrition
Trade can contribute to
• Food security
• Improving nutrition through diversification of food
baskets, producers, and suppliers
• Increasing productivity and sustainability by
facilitating diffusion of technology and innovation
• Giving poor farmers access to high value markets
• Stronger value chains, mitigating conflict, and to
higher quality and quantities of goods and services

Africa regional trade is growing rapidly

BUT ! Significant
regional trade may
go unrecorded.

suggest that intra-
African trade may
be higher than
reported

Intra-regional trade as share of total agricultural trade 2000-2013
23. Johan Swinnen, March 2020
Factors affecting regional trade
1. Tariff levels within RECs are
relatively low
But: overlapping membership complicates
harmonization and coordination within
RECs
2. Deficient trade infrastructure
3. Costly non-tariff measures
Safeguards, SPS standards, technical
barriers to trade (TBTs), IP measures,
rules of origin, etc.

28. Johan Swinnen, March 2020
Trade is crucial for climate adaptation and mitigation
Climate-induced yield changes
generate large price movements and
adjustments in acreage and trade
Poorer countries likely to bear
larger share of costs from climate
impact on agriculture
• Net food importers (Asia, MENA)
• Limited adaptation through trade due
to high trade costs and specialization
in crops with little trade (SSA)
Source: Gouel and Laborde 2018
Market adaptations rely significantly on an international trade system
allowing large reallocations of trade flows

Agricultural and trade policies affect climate change
But, again, the impact is complex

• Smallholder integration is mixed
• Contract enforcement problems are very serious
• Organization of the value chain is endogenous
o to market imperfections
o to enforcement institutions
oto nature of the commodity (incl standards)

• Benefits for the poor can come through 3 channels:

64. Future potential of VCD
for poverty reduction
• Private sector:
o strongest growth in high value sectors (with innovation requirements and
potential)
o Many of the models observed in East Europe in the 1990s are now developing in
higher vl poorer countries, such as SSA
• Public/Private/NGO sector
o Much of the CSR & NGO programs include VC-type elements
o How can one make VCD work in staple food markets ? (80-90% of poor
countries’ agriculture)
65. Example:
VCD model for SSA food staple sourcing
• Special purpose vehicle
(SPV) to source staple
foods by WFP in East
Africa
• Joint project with World
Bank, input supplying
companies and re-
insurance companies

66. Voluntary Sustainability Standards (VSS)
(incl. FairTrade etc)
CASE : Certification in coffee in Ethiopia

colleagues from IFPRI &
LICOS (Bart Minten,

67. VSS Certification in Coffee
Globally:
• VSS rapidly taking off (4%
in 2005, now 20%)
• Coffee leading agricultural
commodity in VSS
In Ethiopia:
• VSS low and slow
• Coffee most important
export product : 25% of its
forex earnings
• 4 million coffee farmers

68. Why low uptake of VSS certification ?
• Transmission of VSS premium to farmer =
30%
• Average coffee farmer in Ethiopia, if all coffee
certified: income increase with 7.5 USD (per
year !)
oWith 100% premium transmission, increase of 20
USD per year…
• Impact of certification on coffee producers’
welfare is small.
• Combined with implementation costs : low
adoption of Fair Trade in Ethiopia

72. Increased Attention to Food Systems
UN Food Systems Summit 2021
Mobilizing commitment to create
systems that are:
Climate resilient
Sustainable
Inclusive
73. What are Food Systems?
Food systems collect “all the elements (environment, people,
inputs, processes, infrastructures, institutions, etc.) and activities
that relate to the production, processing, distribution, preparation
and consumption of food, and the output of these activities,
including socio-economic and environmental outcomes” – HLPE
2017
Ideal food systems are nutrition-, health-, and safety-driven,
productive and efficient (and thus able to deliver affordable food),
environmentally sustainable and climate-smart, and inclusive.
74. What are the benefits of creating inclusive food
systems?
Better integrating marginalized people into national food systems
achieves inclusive economic growth.
Increasing household incomes reduces absolute poverty and
improves access to service.
Inclusive food systems can break the intergenerational cycle of
poverty, hunger, and malnutrition.
Inclusion can help reduce global and national inequalities.
Inclusion is a moral imperative!
