2 2 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO This module is part of a set of power points that describes how works the EX- ACT tool. EX-ACT (Ex-Ante Carbon-balance tool) is a tool developed by Food and Agriculture Organization of the United Nations (FAO). It is aimed at providing estimations of the mitigation impact of agriculture and forestry development projects, estimating net carbon balance from Green House Gas (GHG) emissions and carbon sequestration. It is a land based accounting system associated with the adoption of alternative land management options (See the linked flyer of the EX-ACT tool). The tool is developed with a modular approach, each module going to be described in such a power point. Acknowledgement

3 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO After reading this module, you should: understand how the forest degradation module of EX-ACT works; know which data are required to run the forest degradation module; be able to fill in the forest degradation module by yourself. Objectives

4 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Main view of EX-ACT User needs to click here

5 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Complete view of the Forest degradation module

6 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO How filling it... Simplest approach by default (Tier-1) Approach with more detailed information (Tier-2) 2 possible approaches:

7 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Explanations step by step... 1

8 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Definition of the vegetation By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic This table presents to the user the default vegetations (natural forest or tree plantation) available for the project within the climate zone (according to information provided in the description module)

9 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Definition of the vegetation By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic Those names will be used below as the entries for the vegetation selected

10 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Definition of the vegetation By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic There is a distinction between natural forest and plantation According to the IPCC; planted forest are intensively managed whereas natural forest are extensively managed. The choice between categories can also be redefined according to national circumstances

11 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Coefficients used By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic This table reports the default values for each compartment (pools) of the corresponding previous default vegetations Above-ground biomass Below-ground biomass Soil Litter and dead wood

12 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Coefficients used By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic

13 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...1/4 Coefficients used By default, the adoption of practices is considered as linear. Yet the user can choose between a linear/immediate/exponential dynamic Default values are proposed for the burning, but the user can change these values Except from the previous section of default vegetation options, the user can set up to 4 specific vegetations by indicating its own factors for the different pools

14 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Explanations step by step... 2

15 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...2/4 Definition of the state of degradation User can select one of the preset default vegetation User can also select one of the specific vegetation

16 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...2/4 Definition of the degradation state User informs the state of degradation … for the default types (Tier 1) for the user types (Tier 2) … Within a predetermined list of possible degradation Indicate percentage of degraded area (0, 10, 20, 40, 60, 80 %)

17 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Explanations step by step... 3

18 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Coefficients used Step by step...3/4 This table presents the coefficients and calculations made by the model

19 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Explanations step by step... 4

20 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...4/4 Quantification of the forest degradation User enters the total area of interested forest The tool calculates the corresponding degradation on the same total area User can change the dynamic of degradation (linear, immediate, exponential)

21 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Step by step...4/4 Quantification of the forest degradation Calculations made by the tool Carbon balance of forest degradation

22 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO How filling it...Now you know everything about the Organic soils module... …See the other modules!

23 On-line resource materials for policy making Ex-Ante Carbon-balance Tool Food and Agriculture Organization of the United Nations, FAO Glossary On-line resource materials for policy making Ex-Ante Carbon-balance Tool Global warming potential (GWP) is a measure of how much a given mass of greenhouse gas is estimated to contribute to global warming. It is a relative scale which compares the gas in question to that of the same mass of carbon dioxide (whose GWP is by definition 1) Emission factor: normalized coefficient that allows for calculating the emission fluxes of GHG Carbon sink: system that absorb naturally a part of the CO 2 emitted in the atmosphere and store carbon during a more or less long term Carbon balance: should be considered, for a specific project (or scenario of action) in comparison with a reference, as the net balance of all GHG emissions expressed in CO 2 equivalent (sources and sinks) with the atmosphere interface and the net change in C stocks (biomass, soil…).
