Climate Change and Agriculture: ensuring food production...

Climate Change and Agriculture: ensuring food production is not

threatened.

EPA Public Lecture Series on Climate Change -Dublin - 15 March 2011

Alexandre Meybeck, FAO

A triple Challenge

• More food, in quantity, quality and diversity, everywhere for everyone

• Adapt to Climate Change

• Contribute to mitigate Climate Change

Food and Nutrition Security

• Availability

• Accessibility

• Utilisation

• Stability

Impacts on ecosystems

Main effects on agricultural production

• Decrease of production in certain areas

• Changes in the geography of productions

• Increased variability of production

Projected yields in Morocco

A: irrigated maize and irrigated seasonal vegetables - B: irrigated fruits and vegetables - C: fodder crops and

vegetables - D: rainfed cereals and legumes - E: rainfed wheat and barley - F: Other rainfed crops.

Main impacts of CC on livestock

• Increased risk of heat stress, intensity and frequency

• Availability of water

• Quantity and quality of available and accessible feed

• Modifications in the distribution, intensity and frequency of diseases and parasites (?)

Impact on Food and Nutrition Security

• Impacts on the most vulnerable countries

• Impacts on the most vulnerable people, including small holders

• Impacts on malnutrition

What contribution to mitigation?

Agriculture and Forestry in Global Emissions (IPCC)

Greenhouse gas emission sources/removals in agriculture

Emissions of the agricultural sector (IPCC 2007)

Technical mitigation potential (IPCC 2007)

Food Systems more efficient and resilient

• More food, in quantity, quality and diversity • Adapt to Climate Change• Contribute to mitigate Climate Change

• More resource efficient: use less land, water, inputs to produce more food sustainably

• More resilient to change and shocks

Sustainable intensification of crop production

• Better management of water• Integrated nutrient management• Conservation agriculture• Genetic resources• Ecosystems’ functions• Diversification

Resilience in pastoral systems

Resilience in “Industrial” systems

• Heat stress– Buildings (projections)– Management (previsions)

• Feed accessibility– Increased variability of production and

trade– Increased price volatility

• Flexibility

Diversification

Trade for efficiency & resilience

• Link small holders to markets– Infrastructures– Transparency

• International markets- Information, transparency- Price volatility

Governance

• Need to address comprehensively Food Security and Climate Change, both Adaptation & Mitigation

• At every level, local, national, regional

Cancun Agreement

• Cancun Adaptation Framework • REDD+ (drivers of deforestation)• Green Climate Fund (balanced

allocation between adaptation and mitigation)

• NAMA’s

Link Food Security & Climate Change in international Fora

• CFS has requested a study to HLPE on Food Security & Climate Change

• Cancun Adaptation Framework has to include Food Security concerns
