Default values on carbon stocks in different carbon pools for different land-use categories and subcategories, which are required for baseline and project scenarios, may not be available often. Further, default values of carbon stocks for lands subjected to different periods of degradation are unlikely to be available in literature, and those for rates of change in carbon stocks (above-ground biomass and soil carbon) in degraded, barren, or fallow lands are even less likely to be available. Therefore, most often project developers may have to generate carbon stock data on their own for the land-use categories and land area selected for project activities, particularly under the baseline scenario.
Baseline scenario The approach to estimating carbon stocks based on cross-sectional field studies makes use of field and laboratory measurements. Adopting this approach would require access to land-use categories such as cropland, grassland and degraded lands that are subjected to changes similar to those the proposed project lands are subjected to under the baseline scenario and with comparable rainfall, soil, topography, vegetation cover and management practices. Project scenario Cross-sectional studies involve identification of locations with desired vegetation, soil, topography, management systems and age class for the project activities. At most project locations, forests or plantations of different age and subjected to selected management practices are likely to be available, such as eucalyptus plantations or naturally regenerated forest plots of different age classes promoted under ongoing or past afforestation and reforestation programmes in the region. Plots with similar vegetation characteristics relevant to the project activities may be located even outside the project boundary with similar soil, rainfall and other conditions. If such plots are available, carbon stocks and changes can be estimated based on the field and laboratory methods described in Chapters 10-13. The values for carbon stocks or growth rates thus obtained could be used for the proposed project during the project development phase to calculate or project future carbon stock gain, roundwood production or soil quality improvements.

What you need to know about… Project Management Made Easy! Project management consists of more than just a large building project and can encompass small projects as well. No matter what the size of your project, you need to have some sort of project management. How you manage your project has everything to do with its outcome.
