Global Youth Ministers 2013Food Crisis
Effects of climate change on food security and nutrition
Outline
Focus on… The interaction between climate change and food
production (agriculture) Examples of the most affected regions Challenges and opportunities for food security
VulnerabilityInteraction between climate change and food production
Vulnerability and risks
The risk of the climate change exposure magnitude sensitivity ability to respond and adapt
Components of vulnerability
Biophysical and social factors High population growth and low income Increase the number of malnourished children in
the future Policies (??????????????)
Effects of vulnerability
Individuals Households Communities Agricultural systems (i.e. countries)
Who are the most vulnerable?
ExamplesExamples of most affected regions
General examples
Different cropping systems are sensitive to different climate change▪ E.g.: Rice-based systems are sensitive to high daytime
temperature▪ Potato-based systems are sensitive to high nighttime
temperature
General examples
Countries where humans haul water are more sensitive than those using machines
Countries with fewer diversity of diet are more sensitive than others
Low-income and rural communities are vulnerable
Victims?
Who are the victims? (I) Arid regions (II) Coastal regions (III) Temperate regions (IV) Tropic regions
A. (II) only B. (I), (III), (IV) C. (II), (III) D. (I), (II), (IV)
Most affected regions
Arid and semi-arid regions of the tropics Southand West Asia, India, North Africa, part of dry Andes
in Latin America.
Coastal Areas (at risk of flooding and sea level rise) Countries with agriculture in river deltas Small island states
Regions that already have conflicts for land and water
Most affected systems
Pastoralists and Small scale farmers in dry areas particularly in S. Asia and Africa
Marine fishery production among tropical nations
Small farms that have little access to markets
Effects
With high population growth and low income growth average kilocalorie availability declines in all regions by 2050
Climate change increases the number of malnourished children substantially
Trade flows adjust if trade policies don’t control the current situation
Adaptations, challenges and recommendations
Challenges and opportunities
Adaptation objectives
Adaptation policies are to: Produce more food Build more resilient food systems Consider the needs and rights of farmers Support vulnerable groups and communities Address sustainability
Challenges
EmissionsFood Insecurity
Food productionCost of production
(Just) Recommendations
Adapt policies and actions Principles:
1. Integrate food security and climate change2. Enlarge the base of evidence for policy-making3. Involve all stakeholders in decision-making4. Focus on the needs and contributions of
disadvantaged
(Just) Recommendations
National governments and international organizations
1) Pursue synergies in food security and climate change actions
2) Increase resilience of food systems to climate change3) Develop low-emissions agricultural strategies that
contribute to food security4) Collect information locally and share knowledge globally5) Facilitate participation of all stakeholders in decision
making and implementation
(Just) Recommendations
General Recommendations: Encourage more explicit recognition of food
security negotiations on ▪ Climate change▪ International trade
Enhance the role of civil society Support to improve data collection and a collection
sharing mechanism on international data gathering for climate change and food security
