Agricultural Growth and Food Security
Supply drivers
Climate change
Water and land scarcity
Science and technology policy
Investment in agricultural research
Policy and governance reform
Demand drivers
Population:9 billion people in 2050

Major Consequences
Change in diets to convenience foods, fast foods
Increased consumption of fruits and vegetables
Higher food energy, more sugar, fats and oils
Rapid growth in meat consumption and demand for grains for feed
Half of growth in grain demand will be for livestock
Intense pressure on land and water

Dietary and Food System Approaches to Improving Nutrition
Reducing post harvest losses
• 10% for grains; 25% for perishables
• Economic recoverability limited
Wasting less food
• 20% wastage in households
Consuming fish from sustainable stocks
Reducing consumption of meat and dairy products

Key Question
Page 7
Would reduction in meat consumption in richer countries improve food security in developing countries?
![Page 8: Global diet change: Implications for agriculture and nutrition](https://reader034.vdocument.in/reader034/viewer/2022042813/546c1876b4af9f6b2c8b4ee0/html5/thumbnails/8.jpg)
www.ifpri.org
Dietary Change Is Not Easy
CAMPAIGNS
Advocacy, educational, and public relations campaigns
PROMOTE LOW-MEAT MENUS
Cafeterias, schools, hospitals, and other public-sector institutions
POLICIES
Taxation and subsidy policies to increase the cost of meat compared to other food products

Conclusions
Halving of meat consumption in richer countries has
• small nutrition benefits in developing countries
• big land saving impacts
Dietary change is a useful tool for improved food security and nutrition
But transformative progress requires much broader investment in agricultural and rural development
