CGIAR Centers developed high yielding varieties for staple cereals that were the engine of the Green Revolution
CGIAR: agricultural research for a food-secure future
CGIAR’s research is carried out by 16 Research Programs (CRPs), working in close collaboration with hundreds of partners worldwide
Bridging the gaps between AR and ARD3 examples
• Climate-Smart Agriculture Combining mitigation
and adaptation• The Wheat initiative• Ecological intensification
through healthier water, land and ecosystems
2013
Why is CSA important? – Adaptation

yields: response to warming

Climate drives yield variation: our systems are sensitive to climate, not resilient to it

Why is CSA important? – Mitigation

Agriculture-related activities are 19-29% of global
greenhouse gas emissions (2010)
Agriculture production (e.g., fertilizers, rice, livestock,
energy)
Land-use change and forestry including drained peatlands
Industrial processes Waste

CHINA Paying for ecosystem services
2.5 million farmers paid to set aside land and plant trees
Sequestered over 700,000 tonnes of carbon
2 million ha rehabilitated – reducing erosion
Increased yields
Climate-smart coffee-banana systems Microclimate: shading can reduce
temperature by >2° Celsius Shade biomass increases carbon
stock→ CC mitigation Shade plants increase revenue and
food security for smallholders
income up > 50%
Van Asten et al (2014)
What if… - we spread agroforestry across Africa?
Analysis based on WRI 2013
Approximate area suitable for Agroforestry in Africa:
~ 300 Million Ha140+ Million People below

2 Gt Co2e storage per year corresponds to ~1/3 of Global Direct Ag Emissions
Significantly higher mitigation potential by further increasing tree density and in humid systems
Agroforestry can be combined with other practices such as water harvesting for additional impact.
Direct agricultural emissions are spread across regions and across production sectors

“Ag soils” includes synthetic fertilizers, manure applied to crops, field application of crop residues, and nitrous oxide from cultivated organic soils.
Mitigation opportunities by country
19
Source: CEA analysis.
Mitigation opportunities are clustered primarily in the major agricultural economies.
12 million farmers & 40 different crops insured
INDIA Weather-based insurance
Reduces pressure to bring more land under cultivation
Reduces risks
Allows farmers to access fertilizer and better seed
Adaptations to deal with higher climate variability and climate risks
Towards more transformative change
• Better weather forecasts and climate information reaching farmers, governments, emergency relief
• Social safety nets to help vulnerable people recover from climate shocks
• Weather insurance in agriculture reaching more farmers
CSA Alliance: AR and ARD institutions united with International Organizations and NGOs
Minimum Goals for 2050
Environmental Goals Development Goals
Total Agricultural Production
Nutritionally Complete Production
Biodiversity Conserved
Carbon Sequestered Improved Water Quality
Water Conserved
Soil Formed
Food Security Goals
Food Distribution and Access
Conserve agrobiodiversity
Increased Farmer LivelihoodsAnd Resilience
Improve Human Health
Increase Farm Self Reliance
Adapted from Foley et al 2011
Production Goals
An agriculture that contributes to environmental protection rather than environmental degradation
N-S Partnerships for ecological intensification
