Land Use Categories and Stratification

Using the guidelines provided by the IPCC (IPCC 2003, 2006), the geographic area of the country is categorized according to

• Land-use categories forest land, cropland, grassland, etc.

• Subcategories land remaining in the same use category and land converted to a new land-use category

• Vegetation and management systems

° Forest land evergreen forest, moist deciduous forest, dry forest, mountain systems, scrubland and tropical desert ° Plantations Eucalyptus, Teak, Acacia, Pine, etc., age of the stand (<5 years,

5-10 years, 10-20 years, >20 years) ° Cropland irrigated, rainfed, agroforestry systems, annual and perennial crops, area under rice, sorghum, maize, etc. ° Grassland intensively managed grassland and open-access grazing land, fertilized or irrigated grassland

• Rainfall zones

° Humid, subhumid, semi-arid and arid ° Wet, moist and dry zones

• Other criteria such as soil type, altitude and slope

Disaggregate the geographic area of the country according to the above or some other nationally relevant criteria into homogeneous categories, subcategories or land-use and management systems. Disaggregation or stratification of land-use systems into finer and homogeneous systems will reduce the error or uncertainty in using the carbon stocks and rates of change of different pools for national estimates. However, finer levels of disaggregation add to the cost of inventory estimation and are subject to data limitations, particularly the emission and removal factors.
