“…In Italy, considering the same crop categories used by Chiti et al . (), the model estimation was comparable (490 vs. 526 Mt of C respectively). A marked difference was noticed in Denmark where the CENTURY model clearly underestimated the SOC stock, in particular in the western part of the country.…”

Proposed European policy in the agricultural sector will place higher emphasis on soil organic carbon (SOC), both as an indicator of soil quality and as a means to offset CO2 emissions through soil carbon (C) sequestration. Despite detailed national SOC data sets in several European Union (EU) Member States, a consistent C stock estimation at EU scale remains problematic. Data are often not directly comparable, different methods have been used to obtain values (e.g. sampling, laboratory analysis) and access may be restricted. Therefore, any evolution of EU policies on C accounting and sequestration may be constrained by a lack of an accurate SOC estimation and the availability of tools to carry out scenario analysis, especially for agricultural soils. In this context, a comprehensive model platform was established at a pan-European scale (EU + Serbia, Bosnia and Herzegovina, Croatia, Montenegro, Albania, Former Yugoslav Republic of Macedonia and Norway) using the agro-ecosystem SOC model CENTURY. Almost 164 000 combinations of soil-climate-land use were computed, including the main arable crops, orchards and pasture. The model was implemented with the main management practices (e.g. irrigation, mineral and organic fertilization, tillage) derived from official statistics. The model results were tested against inventories from the European Environment and Observation Network (EIONET) and approximately 20 000 soil samples from the 2009 LUCAS survey, a monitoring project aiming at producing the first coherent, comprehensive and harmonized top-soil data set of the EU based on harmonized sampling and analytical methods. The CENTURY model estimation of the current 0-30 cm SOC stock of agricultural soils was 17.63 Gt; the model uncertainty estimation was below 36% in half of the NUTS2 regions considered. The model predicted an overall increase of this pool according to different climate-emission scenarios up to 2100, with C loss in the south and east of the area (involving 30% of the whole simulated agricultural land) compensated by a gain in central and northern regions. Generally, higher soil respiration was offset by higher C input as a consequence of increased CO2 atmospheric concentration and favourable crop growing conditions, especially in northern Europe. Considering the importance of SOC in future EU policies, this platform of simulation appears to be a very promising tool to orient future policymaking decisions.

“…From 2007, the three different energy crops were arranged in 500 m 2 plots (100 m long and 5 m wide). Several studies demonstrate that changes in land use and management can strongly affect soil organic carbon stock [47,48]. Increasing intensities of harvests from existing agricultural and forestry systems and replacing pasture with short rotation energy crops may deplete soil carbon [49].…”

LCA Study of Oleaginous Bioenergy Chains in a Mediterranean Environment

et al. 2014

This paper reports outcomes of life cycle assessments (LCAs) of three different oleaginous bioenergy chains (oilseed rape, Ethiopian mustard and cardoon) under Southern Europe conditions. Accurate data on field practices previously collected during a three-year study at two sites were used. The vegetable oil produced by oleaginous seeds was used for power generation in medium-speed diesel engines while the crop residues were used in steam power plants. For each bioenergy chain, the environmental impact related to cultivation, transportation of agricultural products and industrial conversion for power generation was evaluated by calculating cumulative energy demand, acidification potential and global warming potential. For all three bioenergy chains, the results of the LCA study show a considerable saving of primary energy (from 70 to 86 GJ· ha −1 ) and greenhouse gas emissions (from 4.1 to 5.2 t CO2· ha −1 ) in comparison to power generation from fossil fuels, although the acidification potential of these bioenergy chains may be twice that of OPEN ACCESSEnergies 2014, 7 6259 conventional power generation. In addition, the study highlights that land use changes due to the cultivation of the abovementioned crops reduce soil organic content and therefore worsen and increase greenhouse gas emissions for all three bioenergy chains. The study also demonstrates that the exploitation of crop residues for energy production greatly contributes to managing environmental impact of the three bioenergy chains.

“…The global production of agricultural crops should be doubled because the world's population, especially in developing countries, is increasing . However, the use of intensive agricultural methods in Middle Eastern countries, where the majority of agricultural soils possess low organic carbon (OC) and nutrients, is resulting in faster fertility degradation . Furthermore, water deficiency is now considered as an additional major limiting factor for agricultural production in this area as one of the main water scarce regions due to huge consumption of available freshwater in this section (approximately 60%) .…”
