N2 - Soils contain approximately three times the world amount of organic carbon present in
vegetation and the double present in atmosphere. Italy, which has joined the Kyoto
Protocol, has decided to consider only forest management within the additional activities
contemplated for the count of carbon credits (CC), and to launch a monitoring campaign
only in forests. The scope of this research work was to estimate CC variations supplied from
both agricultural and forest soils of Italy during last the 3 decades (from 1979 to 2008). The
soil database of Italy was the source of information of soil organic carbon stock (CS), referred
to the first 50 cm depth. The CRA ‐CMA (Research Unit for Climatology and Meteorology
Applied to Agriculture) database was the source of information for mean annual
temperature and mean annual precipitations of the two periods 1961‐1990 and 1991‐2006.
Multiple linear regression analysis were used to interpolate the CS with geographic
attributes as predictive variables. An index of climatic change influence on soil organic
carbon variations (Ic) was calculated. The net CS variations, that may be attributed to
agricultural and forest management change, were calculated subtracting the ones due to
climate change. The calculation of CC was done following the Emission Trading System (EUETS,
EU Directive 2003/87/EC), and the exchange rate given by the Carbon Dioxide Emission
Allowances Electronic Trading System (SENDECO2) at September 2010. The Italian CS passed
from 3,32 Pg in 1979‐1988, to 2,74 Pg in 1989‐1998, and 2,93 Pg in 1999‐2008. The CC lost
from the first to the second decade totalled some 31,171 M€, while the CC recovered from
the second to the third were about 9,218 M€. About 90 % of the recover was due to the
management change in arable lands. Italy should then extend also to arable lands the CS
monitoring.
Keywords: Carbon sequestration, Land management, Climate change impact, Environmental
economics.
