"This project contributes to advancing the state-of-the-art in environmental science and the geosciences in the specific area of applied system analysis and integrating modeling of spatially explicit verified greenhouse gas (GHG) inventory with a focus on forest carbon accounting. GHG (mainly carbon dioxide) emissions and removals in forests considerably vary from one region to another due to the different forests characteristics (bioclimatic zones, plant type, age, soil type, etc.). Spatial inventory of emissions and sinks in forestry at local scale significantly reduces uncertainty in inventory results. The proposal comprises the advantages of using spatial approaches to analyze emissions/removals of carbon dioxide in forestry at different spatial levels (from individual to national forest land). The georeferred integrated forest carbon accounting system will be based on mathematical models of forest carbon account and emissions/removals in forestry and information system for the analysis of scenarios of emissions/removals for various commercial demands for wood, energy and international measures to reduce emissions. It will contain a database of forest parameters, including geographic information to communicate with digital maps, models of carbon balance and algorithms for automatic estimation of forest parameters and a convenient user interface. The spatially integrated forest carbon accounting system can be used for economic and financial analysis of effectiveness of measures to reduce emissions or to increase removals as a tool to support decision making at the local, national and international levels."
