6D.1 1 UNFCCC - NAI SOFTWARE Sector: Agriculture Practical Aspects and Exercises CGE Greenhouse Gas Inventory Hands – on Training Workshop for the African Region Pretoria, South Africa 18 – 22 September 2006

6D.2 2 CONTENT Specific details of the UNFCCC -NAI Software use to calculate GHG emissions in the sector Agriculture. Practical exercises (to be solved by the participants after the presentation).

6D.3 3 BACKGROUND The choice of a good practice method is given by the decision threes in the IPCC GPG according to national circumstances. The UNFCCC -NAI Software contains, basically, the methods of smaller complexity that can use countries for the preparation of inventories. However, in principle, the software can be used to report the estimated emissions independently of the complexity of used method (Tier 2, 3 etc).

6D SECTOR: AGRICULTURE Exercise 4.2: CH4 Emissions from Rice Cultivation (I) Country A: Year: Worksheet 4-2s1 Data According with the data submitted by the Ministry of Agriculture in the country during the year, were cultivated ha of intermittently flooded paddy fields (single aeration) and ha of upland rice. Was used non – fermented organic amendments. Actual data on soil types subject to composting is not available. Cultivated area (ha) Cropping seasons Water management regime Amount of organic amendment applied as dry matter (t/ha) Intermittently flooded (single aeration) Upland rice3

6D SECTOR: AGRICULTURE Exercise 4.2: CH4 Emissions from Rice Cultivation (III) Tasks Using the UNFCCC -NAI Software: 1.Calculates CH4 emissions. 2.Verifies the emissions report in the Sectoral and Summary Tables. 3.Fills the Table 8A (Overview Table) for the self evaluation of quality and completeness. 4.Print the used worksheet, the Sectoral Summary Table and the Overview Table (8A).

6D SECTOR: AGRICULTURE Exercise 4.2: CH4 Emissions from Rice Cultivation (IV) Steps 1.Open the software and select in the Agriculture sector the worksheet 4-2s1 CH4 Emissions from Flooded Rice Fields. 2.Enter in column A the harvested area by water management regime (in 1000 ha). The harvested area is given by the cultivated area times the number of cropping seasons. Area cultivated under upland (or dry conditions) is excluded from calculations. 3.Enter the scaling factor for CH4 emissions in column B. Default value = 0,5 (relative to EF for continuously flooded fields).

6D SECTOR: AGRICULTURE Exercise 4.2: CH4 Emissions from Rice Cultivation (V) Steps 4.Enter a correction factor (scaling factor) for organic amendment in column C = 2,5 5.Enter in D the Seasonally Integrated CH4 EF for continuously flooded rice without organic amendment = 20g/m 2. 6.In column E the software calculates CH4 emissions (Gg).
