Actual provision as an alternative criterion to improve the efficiency of payments for ecosystem services for C sequestration in semiarid vineyards
2016
The aim of this paper is to evaluate the efficiency of the PES scheme actually used in the Sicilian rural development program, based on an egalitarian criterion, and proposing an alternative scheme in order to guarantee a greater equity and fairness of premium distribution in relation to soil carbon (C) sequestration potential. We, first, assessed the ecosystem services (ES) provided by agri-environmental measures (AEM) in terms of SOC stock increase in Sicilian vineyards. Based on these data we evaluated the efficiency of agro-environmental payments according to an egalitarian criterion and simulated the effects of the actual provision criterion adoption. Results showed that the adoption o…
Estimating carbon credits variations supplied from agricultural and forest soils of Italy between 1979 and 2008.
2011
Soils contain approximately three times the world amount of organic carbon in vegetation and approximately the double of that present in the atmosphere. However, soil organic carbon (SOC) has been found lowering in many areas, while atmospheric CO2 was on increase. It is well known that there is a marked inter-dependence between SOC and climate, nevertheless, recent researches have demonstrated that changes of land use and management can cause gains or losses of SOC greater than climatic changes. 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, and to launch a monitoring …
