“…Policymaking within this problem area is therefore an intricate matter and has to be supported by information from scientifically based analyses. New models and tools are being developed for this purpose, such as the model CO2FIX (Nabuurs et al, 2002;Masera et al, 2003). Other models, developed for describing forest development in general, can also be used for carbon sequestration analysis; examples are FORSKA (Prentice and Leemans, 1990;Prentice et al, 1993;Lasch et al, 1999;Lasch et al, 2002), FORECAST Seely et al, 1999;Seely et al, 2002) and CENTURY (Parton et al, 1987;Jiang et al, 2002;Song and Woodcock, 2003).…”
