1. The global food system is facing challenges from rapid urbanization, changing diets, and environmental degradation while malnutrition persists. 2. Conflict is a key driver of hunger for 74 million people and famine risk is rising. 3. Rapid urbanization and growth of the middle class is changing diets and increasing pressure on food systems while the food industry expands globally.

• Urban poor face challenges in access to high-
quality, diverse, safe, and affordable diets
• As incomes increase urban consumers more
likely to consume imbalanced diets that are
‒ Heavy on processed foods
‒ High in calories, saturated fats, refined sugars,
and salt
‒ Low in fiber
• Poor diets among urban residents resulting
from
‒ Availability and marketing of energy-rich,
nutrient-poor foods
‒ Changes in life styles and types of employment,
especially for women
Urban areas face unique challenges

Food industry is expanding, especially in
developing countries
• Increased consolidation and vertical coordination
• Modernization and expansion of food sector, particularly
at midstream stages
‒ Opportunities for job creation, diet diversification,
increased food safety
• Expansion of supermarkets changing nature of food
distribution
‒ By mid-2000s supermarkets controlled up to 50% of food
market in Southeast Asia and Central America
• ICTs and online distribution channels continue to change
market organization and access to food

agriculture

Automation and mechanization
• Increasing use of machines and
electronics in agriculture
• Implications on youth unemployment
– need to move jobs to post-harvest
service sector
Hydroponic, vertical or indoor
farming
• Estimated US$750 million in North
American private investment in
vertical farming (through Q3 2017)
• Economically viable and sustainable
Biotechnology
Source: Indoor Ag-Con 2016
• Gene sequencing
‒ Dramatic reduction in cost to ~US $1,121/genome
‒ Sequenced crop
genomes could
improve agriculture in
challenging climates
• ‘Cultured’ meat
‒ Production involves 78-96% lower GHG emissions,
99% lower land use, 82-96% lower water use
depending on conventional meat product compared

Reshaping food systems is key to address
global trends

15. Shenggen Fan, July 2018
Promote nutritious, sustainable, and healthy diets
• Tax nutrient-poor foods and subsidize nutrient-rich foods
‒ Divert funds to promote carbon neutral or low carbon food
production (e.g. Brazil’s carbon neutral beef)
• Taxing emissions-intensive foods (e.g. meat and dairy) could
avoid more than 100,000 deaths in 2020

Changes in prices and consumption by
food commodity (%)
Convert inefficient subsidies of unhealthy foods and
inputs to
• Support production of fruits, vegetables, and other nutrient-
rich foods
• Provide income support for vulnerable groups, including
smallholders, women, and youth
Prioritize policies for health and the environment
Environmental footprint of various foods

Strengthen rural-urban linkages
• Improve policy coordination between rural and urban areas
• Support efficient and inclusive rural-urban value chains
• Leverage towns and intermediate cities to facilitate socio-economic links
Promote effective governance mechanisms
• Integrate and coordinate relevant sectors
• Enhance monitoring and accountability with data
Improve governance in urban and rural areas
Support informal economy in urban areas
• Improve policies for effective oversight and safety without stifling commerce or access
– E.g. Zambia’s inclusive management boards of informal markets
• Provide training and education, especially for food safety standards
– E.g. Kenya’s Dairy Traders Association trains informal milk traders on basic
hygiene and quality testing

17. Shenggen Fan, July 2018
Invest in evidence-based techs for health and the environment
• Yield enhancing technologies (e.g. Precision agriculture)
‒ Microdosing in Niger, Mali, Burkina Faso saw millet yields increase by over 50% & better water
absorption (ICRISAT)
• Improved, climate-resilient varieties (e.g. C4 Rice)
‒ Increased rice yields by 50% and N-use efficiency by 30% (IRRI)
• Nutrition-driven and nutrition-sensitive technologies (e.g. Biofortification)
‒ More than 30 million people are consuming one or more of 12 biofortified crops globally (HarvestPlus)

Scale up new multiple-win technologies
• Foster an “innovative ecosystem” – enabling innovators to engage in iterative processes
• Encourage global networks for sharing ideas and learning across markets and
geographies
Use ICTs to link smallholders to urban consumers
• E-commerce connecting rural farmers with supply and demand information
(e.g. China’s G20 initiative)
Promote multiple-win technological innovations
