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.

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

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

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

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.

crop production capacity (ongoing work):

• CCAFS Mitigation Option Tool

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.

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

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
