Modeling carbon sequestration in afforestation and forest magement projects: the CO2FIX V 2.0 approach

The paper describes the Version 2 of the CO2FIX (CO2FIX V.2) model, a user-friendly
tool for dynamically estimating the carbon sequestration potential of forest
management, agroforesty and afforestation projects. CO2FIX V.2 is a multi-cohort
ecosystem-level model based on carbon accounting of forest stands, including forest
biomass, soils and products. Carbon stored in living biomass is estimated with a forest
cohort model that allows for competition, natural mortality, logging, and mortality due to
logging damage. Soil carbon is modeled using five stock pools, three for litter and two
for humus. The dynamics of carbon stored in wood products is simulated with a set of
pools for short-, medium- and long-lived products, and includes processing efficiency,
re-use of by-products, recycling, and disposal forms. The CO2FIX V.2 model estimates
total carbon balance of alternative management regimes in both even and uneven-aged
forests, and thus has a wide applicability for both temperate and tropical conditions.
Results for the model testing and validation in selected temperate and tropical forest
management systems are presented and discussed.
