A microRaman and internal microstratigraphic study of ceramic sherds from the kilns of the Medici castle at Cafaggiolo
Nine representative sherds from the old (14th–16th century) kilns at the Castle of Cafaggiolo in Tuscany have been analysed by means of internal microstratigraphic analyses and micro-Raman spectroscopy and classified as follows: six engobed and glazed fragments, of which three are covered with an opaque white, decorated layer, one is marbleized, and two are engobed. The surface of the two engobed sherds, fragments of unfinished products, indicates that at least two firing processes were used. Two samples show characteristics of Byzantine pottery, and three of them can be classified as Islamic ware or maiolica, whilst the other one displays intermediate characteristics. The variety of ceramic wares indicates the presence of craftsmen with differing expertise, and suggests that part of their work was dedicated to experimentation on new ceramic production techniques

Assessing Deadwood Using Harmonized National Forest Inventory Data
L'articolo è disponibile sul sito dell'editore www.safnet.orgDeadwood plays an important role in forest ecological processes and is fundamental for the
maintenance of biological diversity. Further, it is a forest carbon pool whose assessment must be reported for
international agreements dealing with protection and forest management sustainability. Despite wide agreement
on deadwood monitoring by national forest inventories (NFIs), much work is still necessary to clarify definitions
so that estimates can be directly compared or aggregated for international reporting. There is an urgent need for
an international consensus on definitions and agreement on harmonization methods. The study addresses two
main objectives: to analyze the feasibility of harmonization procedures for deadwood estimates and to evaluate
the impact of the harmonization process based on different definitions on final deadwood estimates. Results are
reported for an experimental harmonization test using NFI deadwood data from 9,208 sample plots measured in
nine European countries and the United States. Harmonization methods were investigated for volume by spatial
position (lying or standing), decay classes, and woody species accompanied by accuracy assessments. Estimates
of mean plot volume based on harmonized definitions with minimum length/height of 1 m and minimum
diameter thresholds of 10, 12, and 20 cm were on average 3, 8, and 30% smaller, respectively, than estimates
based on national definitions. Volume differences were less when estimated for various deadwood categories. An
accuracy assessment demonstrated that, on average, the harmonization procedures did not substantially alter
deadwood observations (root mean square error 23.17%)
Land use inventory as framework for environmental accounting: an application in Italy
L'articolo è disponibile sul sito dell'editore www.sisef.itLand use inventories are sound measures to provide information on the area
occupied by different land use or land cover types and their changes, although
less widespread than traditional mapping; as such, they are distinctively wellestablished
tools for generating statistics on the state and the dynamics of land
use in the European Union. Italy has recently set up a land use inventory system
(IUTI) as a key instrument for accounting removals and emissions of greenhouse
gases (GHG) associated to land use, land use change and forestry (LULUCF)
activities elected by Italy under the Kyoto Protocol. IUTI adopts a statistical
sampling procedure to estimate the area covered by LULUCF land use
categories in Italy, and associated uncertainty estimates. Estimates of land use
have been so far processed for the period 1990-2008 and highlight three interlinked
land use change patterns in Italy: (i) increase in forest land for a total
uptake of 1.7% of the Italian territory; forest cover estimates, with a standard
error of 0.1%, indicate an annual increase of forestland higher over the period
1990-2000 (32 901 ha year-1) than in 2000-2008 (22 857 ha year-1); surprisingly,
also a significant deforestation rate is observed (-7000 ha year-1), due to
forest land conversion mainly into artificial areas; (ii) consumption of arable
land (-4.2% of the Italian territory) primarily due to land uptake by urban areas
and to conversions to permanent crops (mainly orchards and vineyards); (iii)
urban sprawl uptakes 1.6% of the Italian territory in this period, with a total
coverage of settlements reaching 7.1% of total land surface in Italy in 2008.
Overall, land use dynamic results in land uptake by forest land is of the same
magnitude of land uptake by urban areas, but the effects of these processes on
GHG removals (by forest sinks) and emissions (by urban areas) is expected to
be significantly different. In a broader perspective, IUTI methodology, by
providing reliable estimates and well-defined levels of statistical uncertainty
for assessing stocks and flows of land use at national level, can be further implemented
to frame other key questions for sustainable development policies,
like the set up of environmental-economic accounting systems
