objectives
1. Identify and develop pro-poor
adaptation, risk
management and mitigation
practices, technologies and
policies for agriculture and
food systems.
2. Support agricultural issues in
climate change policies, and
of climate issues inagricultural
policies, at all levels.
11. Climate variability and change
Improved
Technologies, practices, policies environmental
and capacity enhancement: benefits
1. Adaptation to progressive climate Improved
change livelihoods
2. Adaptation through managing
climate risk Improved
3. Pro-poor climate change food security
mitigation
4. Integration for decision making
Enhanced adaptive
capacity in agricultural,
NRM & food systems

17. Opportunities to reduce emissions or
increase sequestration in Ethiopia
Management option Mitigation Potential Actions required
Livestock High Technical options?
Soil C sequestration Moderate Incentives? Monitoring?
Reduced burning Moderate Technical options?
Fertilizer Low to date Future efficiencies,
sustainable
intensification?
18. Other research in East Africa
GHG quantification
- Livestock system inventory methods (ILRI)
- Simple and cost effective MRV
- Regional capacity building
19. Improving benefits from carbon
market projects involving farmers
7 projects In collaboration with Ecoagriculture, ICRAF:
•Humbo Reforestation Project, World Vision, Ethiopia
•Vi Agroforestry, CARE, TIST, Kenya
•Ecotrust, NFA, Uganda
• Cocoa Carbon Initiative, Ghana
Lessons
- Real benefits from yields, not payments ($2/yr)
- Need to decrease costs and risks
- Pre-existing institutions, upfront finance critical
- Monitoring livelihoods not a priority

CCAFS is rising to this challenge with a program of integrated research and policy work, across agriculture and food systems
Challenge Program then CGIAR Research ProgramTheme Leaders spread across CG system and the global change community in advanced research institutesNew way of working – deliberately networked
Livestock 82% Land use change 14%, total, fertilizer .0%, burning (Ch4 and N20) 2%500 m resolution HIGH uncertainty likely four East African countries account for 70% of the total emission from the nine countries, dominated by the emissions from land use change and livestock in Ethiopia – total emissions that we report here are comparable to those reported by each country in their National Communications, though as expected our estimates are higher reflecting likely increases in agriculture production since the time of their reports (Table 11). However, the estimates for different gases vary, for example the nitrous oxide emissions reported in the National Communications for the focal countries and year (< 11,000 t CO2e/yr for Kenya to about 6 million t CO2e/yr for Ethiopia) bear no resemblance to the estimates we obtained in Table 11.
