4. Mitigation options tool
• Partnership between the CGIAR programme on
Climate Change, Agriculture and Food Security
(CCAFS) & University of Aberdeen.
• This tool is still being developed;
• The CCAFS Mitigation Options Tool estimates
GHGs emissions from multiple crop and livestock
management systems in different world regions;
• To provide decision-makers reliable information
needed to make science-informed decisions
about emissions reductions from agriculture.

5. CGIAR goals: Reduce poverty, improve food and
nutrition for health, improve ecosystems and services

6. CGIAR research programme (16 RP) on
Climate Change, Agriculture, Food
Security
• Research Themes:
- Climate Smart Agricultural Practices
- Climate Risk Management
- Low Emissions Agriculture √
- Gender and Equity
- Policies and Institutions

7. GHG accounting tools
• Whittaker et al. (2013); Colomb et al. (2012)
reviewed calculators
- CALM
- Cool Farm Tool
- C-Plan
- COMET-Planner
- AFOLU-Calculator
- EX-ACT

8. What distinguishes the CCAFS tool?
- It estimates GHG emissions in several crops, rice and livestock X;
- It estimates the mitigation potential of several management
options √;
- It ranks the mitigation options according to their mitigation
potential √;
- It joins several empirical models to estimate GHG emissions √ .
General characteristics of the screening tool:
- Excel-based tool;
- Easy and quick to fill (5-10 minutes);
- Easy to get the results.

9. Empirical models in the tool

•Preseason water regime
•Water regime of the growing season
•Type and amount of organic fertiliser

12. Mitigacion options
• We chose mitigation options that do not affect
crop production capacity (ongoing work):
Zero-tillage (e.g. maize)
Nitrification inhibitors
Manure
AgroforestryCover crops
Fertiliser
production

13. • CCAFS Mitigation Option Tool

14. Summary
• An Excel-based tool – can be used in any pc;
• Uses empirical models different from IPCC
factors;
• Provides information about mitigation options
and their mitigation potential;
• Maximum time required is 10 min;
• Advanced and quick user - Accommodates a
range of users.
• It is intended to help decision-makers
understanding GHG emissions mitigation.

15. Further work
• Objectives CCAFS: Support better global
knowledge about GHG emissions and low
emissions agriculture policy; Support South-
South training.
• Quantifying livestock emissions (cattle and
land use change);
• Socio-economic barriers to implementation of
mitigation options;
• Links between mitigation and adaptation

16. Discussion
- What are the most important subsectors and practices represented? (e.g.
for max emission reductions as well as decisions facing these groups)
- Is this information useful?
- What is the desired degree of robustness?
- What further information is needed?
- Examples of decisions for which you could use this tool?
- Which groups would be more interested in using the tool?
- How to improve usability for the most relevant groups?
- Leaflet CCAFS
