Abstract. Nitrous oxide (N20 ) emissions were measured weekly to fortnightly between April 2001 and March 2002 from two riparian ecosystems draining different agricultural fields. The fields differed in the nature of the crop grown and the amount of fertiliser applied. Soil water content and soil temperature were very important controls of N20 emission rates, with a 'threshold' response at 24% moisture content (by volume) and 8°e, below which N20 emission was very low. N20 fluxes were higher at the site that had received the most fertiliser N, but N0 3 was not a limiting factor at either site. There was also a ' threshold' effect of rainfall, in which major rainfall events (:::: 10 mm) triggered a pulse of high N20 emission if none of the other environmental factors were limiting. These results suggest the existence of multiple controls on N20 emissions operating at a range of spatial and temporal scales and that non-linear relationships, perhaps with a hierarchical structure, are needed to model these emissions from riparian ecosystems.

“…About 70% of the total globally emitted N 20 is derived from soils (Bouwman , 1990) and agriculture as a whole (i.e., animal excreta, denitrification of leached nitrate (N0 3 ), etc.) contributes about 81% of the anthropogenic N 20 emissions (Brown et al, 2001).…”

“…Furthermore, the complexity of these interactions makes prediction of N 2 O emissions and simple relationships between fluxes and factors difficult to obtain. In order to derive more reliable estimates of N 2 O emission, interactive Brown et al (2001) show, the IPCC default values are gross approximations. Those wanting more precise estimates must resort to site-specific measurements or dynamic models such as DNDC (Li et al, 1992(Li et al, , 1996 or SUNDIAL [1996][1997][1998] mineral N '-' Data not determined or not published *: typic rendzic leptosol, gleyic luvisol, eutric leptosol Temperatures are annual means except for the following studies: Henault et al, 1998 (3 months), Martikainen et al, 1994 (9 months), Regina et al, 1996 (9 months) …”

The results of a literature study examining quantitative estimates of N 2 O emission rates are presented for a range of land-uses across Europe. The analysis shows that the highest N 2 O emission rates are for agricultural lands compared to forests and grasslands. The main factors regulating these rates are available mineral nitrogen, soil temperature, soil water content and the available labile organic compounds. These controls operate across different time-scales, all must exceed a certain threshold for N 2 O emission to occur. The results support the need for an emission factor function of land-use and climate within models describing nitrogen dynamics in catchments. This would allow the assessment of the net N 2 O emission within catchments in terms of current levels and potential changes associated with climate variability, climate change and land use change.

“…Emissions from fossil diesel combustion in are calculated using IPCC methodology, module 1 Energy, and emissions from nitrogen fertilizer (N 2 O) using module 4 Agriculture. We are aware that some authors [21] show that in some conditions the default value used to calculate emissions are not representative, and they can underestimate or overestimate relative emissions values. We are sure that for specific processes at local scale, an appropriate approach could be found; however, IPCC methodology is widely used and the only one scientifically accepted, even if it needs improvement.…”

In the last decade a great number of studies have been carried out on the possible use of biofuels in order to reduce greenhouse gas emissions. Among biofuels, biodiesel has gained considerable attention as the need to develop alternatives to traditional diesel fuel increases. The Italian parliament adopted directive 2003/30/CE from the European Parliament, in which the guidelines about future production and consumption of biofuels are reported: 1% and 2.5% of biofuels within 2005 and 2010 respectively. The aim of this work is to investigate the reduction in greenhouse gas emission obtained by using biodiesel in agricultural practises, and the role of renewable energy use at a local scale. Comparison between diesel and sunflower methyl ester was made from the point of view of an emission inventory, from production and combustion, by using different scientific tools, such as IPCC methodology and the Danish Life Cycle Assessment (LCA) EDIP Database. Results show that the use of sunflower methyl ester, other than the renewability of CO 2 emitted, implies a general reduction of CO 2 equivalent emissions of up to 57%.
