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).

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).

• Country A Year 2000.
• Data
• The National Statistics Office provided data from
  domestic livestock population in the country for
  the year 2000 (three years average centered in
  2000) .
• Determine the CH4 emissions from the enteric
  fermentation and manure management using the
  CMNUCC-NAI software.
• Verify in the Table of Sectoral Report and the
  Summary Table of the Inventory the report of the
  results obtained

from Rice Cultivation (I)

• Country A Year 2000. Worksheet 4-2s1
• Data
• According with the data submitted by the Ministry
  of Agriculture in the country during the year,
  were cultivated 400 000 ha of intermittently
  flooded paddy fields (single aeration) and 50 000
  ha of upland rice. Was used non fermented
  organic amendments. Actual data on soil types
  subject to composting is not available.

• Tasks
• Using the UNFCCC -NAI Software
• Calculates CH4 emissions.
• Verifies the emissions report in the Sectoral and
  Summary Tables.
• Fills the Table 8A (Overview Table) for the self
  evaluation of quality and completeness.
• Print the used worksheet, the Sectoral Summary
  Table and the Overview Table (8A).

SECTOR AGRICULTUREExercise 4.2 CH4 Emissions
from Rice Cultivation (IV)

• Steps
• Open the software and select in the Agriculture
  sector the worksheet 4-2s1 CH4 Emissions from
  Flooded Rice Fields.
• 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.
• Enter the scaling factor for CH4 emissions in
  column B. Default value 0,5 (relative to EF for
  continuously flooded fields).

• Enter in D the Seasonally Integrated CH4 EF for
  continuously flooded rice without organic
  amendment 20g/m2.
• In column E the software calculates CH4
  emissions (Gg).
