EX-ACT is a FAO tool to estimate the mitigation impact of agricultural and forestry projects
External partnership
and helps decision-making within agriculture and forestryplanning policies and investment projects
The need of a new simple tool
Lack of tools that would help project designers to integrate significant climate response activities in AFOLU* sectors.
Lack of operational tools

Default values
*AFOLU: agriculture, forestry and land use
The need of a new simple tool
Lack of tools screening the whole agricultural sector
The need of a new simple tool
Need for an acceptable method which: measures C-balance impact within ex-ante appraisal, complements usual economic analysis, and fits within the time constraints of formulation process.
Simple
Practical
Cost effective
Upgradable overtime
Information that :-scientists can quantify/use, -farmers/project developers can understand/use
Up-scaling(Able to extrapolate to region, watershed and community basis)
Appraisal of agricultural project/programmes
Carbon balance with a reference scenario
Mitigation impacts of policies and value chains
Regular up-dating
Easy to use and implement
International application
Mitigation non integrated within project formulation
Lack of climate impact decision-making tools
Enriching usual economic analysis with a new
indicator
Adapting to project formulation constraints
Legitimity of a new tool
The need of a new simple tool
Presentation of the tool
The Role of EX-ACT
Takes into account activities
that impact GHG fluxes (emissions and sinks)
Deforestation, A-Re/forestation, forest degradation, Restoration of grasslands, livestock, cultivation of annual crops, cultivation of perennial crops, fertilization of crops, installation of building, installation of irrigation systems...
CO2, CH4, N2O
from and to different pools
above-ground biomass, below-ground biomass, soil, litter and dead wood
EMISSIONS STOCKS
Positive result : There are more emissions
Negative result: There are less emissions
MITIGATION !
Carbon balance in t of eq-CO2
The carbon balance, for a specific project (or scenario of action) in comparison with a reference, should be considered as the net balance of all GHG emissions
expressed in CO2 equivalent (sources and sinks) with the atmosphere interface and the net change in C stocks (biomass, soil…).
Future without project
100 ha flooded rice
100 ha degraded pastures
100 animals
Future with project
100 ha improved irrig. rice
100 ha restored pastures
100 High productivity animals

3 different dynamics of change (adoption) of practice
The structure and the logic of EX-ACT: Main kind of data/information needed
-Different areas of land uses and land use changes in ha
-Management practices (residue burning, improved agronomic practice, nutrient management, organic management, tillage management)
-Quantities of inputs used
-For livestock, evolution of herd
- Energy consumption
- Investments in infrastructure
Activities foreseen… that may impact on mitigation (GHG reduction/releases)
What is the current situation ?
What would happen in the future if the project
is not implemented ?
What is expected in the future if the project is
implemented ?
• It computes the C balance with and without the project. The difference represents the benefits of the project and indicates the net amount of C sequestered (C sink) as a result of the project.
• It illustrates weather the project is able to supply environmental services in the form of C sequestration, thus contributing to climate change (CC) mitigation.
• Outputs could be used in financial and economic analysis of the project, guiding the project design process and the decision making on funding aspects
• EX-ACT could therefore help project designers to select the project activities which have higher benefits both in economic and CC mitigation terms (added value of the project)
• Put forward the multiple benefit of carbon as public good : Value to farmer, Value to community, Value to society
