Cover crops (CCs) adoption is promoted in NT systems because CCs growth curbs nitrate losses via leaching. However, incorporating CC residues into the soil may have positive or negative effects on N2O emissions depending on CC species and agro-ecosystem management. A better understanding of how tillage practices and CC species affect N2O emissions is therefore needed for the development of productive agroecosystems that contribute to climate change mitigation. The objectives of this three-year (2015\u20132017) field experiment on a Udertic Haplustalf soil in the Po Valley were to compare N2O emissions and crop yield of soybean under NT and CT, and to examine how contrasting residues from two CCs (rye, Secale cereale L. vs hairy vetch, Vicia villosa Roth) affect N2O emissions in NT soybean and maize. We hypothesized that N2O emissions would be lower with NT than with CT and with rye residues than with vetch ones. Nitrous oxide was continuously sampled using automatic chambers during three periods (emergence, N-fixation and maturity) over the soybean-cropping season in 2015 and during the entire cropping maize season in 2017. The DNDC model was calibrated (2015 data) and validated (2017 data), and then used to estimate the annual cumulative N2O emissions in different treatments. Overall, N2O emissions in NT were 40\u201355% lower than in CT, for both in situ measurements (Period I) and modelled estimations. These differences could be ascribed to the higher water-filled pore space (WFPS) and soil nitrate availability in CT than in NT. No-till also increased SOC content (28%; 0\u20135\u2009cm) and earthworm abundance (5 times) compared with CT. Within NT systems, N2O emissions were 20\u201336% lower with rye CC than with vetch CC (P", "keywords": ["2.

This scarcity highlights the importance of developing advanced decision tools to evaluate these contributions and create effective mitigation strategies. Our study establishes the first integrated modeling framework that combines a process-based model SWAT+ with a linear mixed model (LMM) to predict N2O emissions from a headwater agricultural river system in Belgium under diverse climate change and fertilization scenarios. In particular, the calibrated and validated SWAT+ model was used to simulate streamflow, nutrient transport, and crop yields under these scenarios, from which, together with biochemical data collected from sampling campaigns, riverine N2O emissions were predicted via LMM. Our results revealed hydrologically driven patterns in riverine N2O emissions, with peak emissions in winter and spring, driven by precipitations enhancing shallow subsurface flows, carrying leached nutrients from fields to the river, and fueling N2O emissions. These phenomena were intensified under climate change scenarios, especially during combined wetter and hotter winters and springs, which elevated headwater N2O emissions by 40 %. Moreover, when coupling these conditions with a 20 % increase in fertilizer rates, riverine N2O emissions would be boosted by 83 %.

The impact of organic, compared with conventional, farming practices on N leaching loss was studied for Danish mixed dairy and arable farms using an N balance approach based on representative data. On mixed dairy farms, a simple N balance method was used to estimate N surplus and N leaching loss. On arable farms, the simple N balance method was unreliable due to changes in the soil N pool. Consequently, the Farm ASSEssment Tool (FASSET) simulation model was used to estimate N surplus, N leaching loss and the changes in the soil N pool.

The study found a lower N leaching loss from organic than conventional mixed dairy farms, primarily due to lower N inputs. On organic arable farms, the soil N pool increased over time but the N leaching loss was comparable with conventional arable farms. The soil N pool was increased primarily by organic farming practices and incorporation of straw. The highest increase in the soil N pool was seen on soils with a low initial level of organic matter. The N leaching loss was dependent on soil type, the use of catch crops and the level of soil organic matter, whereas incorporation of straw had a minor effect. N leaching was highest on sandy soils with a high level of soil organic matter and no catch crops. The present results stress the importance of using representative data from organic and conventional farming practices in comparative studies of N leaching loss. Lack of representative data has been a major weakness of previous comparisons on N leaching losses on organic and conventional farms.

Variability in LCA needs to be clearly distinguished from uncertainty. This paper uses specific examples from the production of diesel and jet fuels from 14 different feedstocks to demonstrate general trends in the types and magnitudes of variability present in life cycle greenhouse gas (LC-GHG) inventories of middle distillate fuels. Sources of variability have been categorized as pathway specific, coproduct usage and allocation, and land use change. The results of this research demonstrate that subjective choices such as coproduct usage and allocation methodology can be more important sources of variability in the LC-GHG inventory of a fuel option than the process and energy use of fuel production. Through the application of a consistent analysis methodology across all fuel options, the influence of these subjective biases is minimized, and the LC-GHG inventories for each feedstock-to-fuel option can be effectively compared and discussed. By considering the types and magnitudes of variability across multiple fuel pathways, it is evident that LCA results should be presented as a range instead of a point value.

Pre-season mineral N was determined in 20 cm sections to 120 cm depth by soil auguring in seven land use systems. Thereafter, sequential soil auguring was done at two-week intervals in plots that previously had 2-year fallows of Acacia angustissima, Sesbania sesban and unfertilized maize to determine mineral N dynamics. Using the static chamber technique, N2O fluxes were also determined in the same plots. Pre-season NH4-N concentrations were > 12 kg N ha-1 in the 0-20 cm layer for treatments that had a pronounced litter layer. NO 3-N concentrations below 60 cm depth were 10 kg N ha-1 layer-1 in the control plots where maize had been cultivated each year. There was a flush of NO 3-N in the Sesbania and Acacia plots with the first rains. Topsoil NO3-N had increased to > 29 kg N ha-1 by the time of establishing the maize crop. This increase in NO3-N in the topsoil was not sustained as concentrations decreased rapidly within three weeks of maize planting, to amounts of 8.6 kg N ha-1 and 11.2 kg N ha -1 for the Sesbania and Acacia plots, respectively. Total NO 3-N leaching losses from the 0-40 cm layer ranged from 29-40 kg ha-1 for Sesbania and Acacia plots within two weeks when 104 mm rainfall was received to an already fully recharged soil profile. Nitrate then accumulated below the 40 cm depth during early season when the maize had not developed a sufficient root length density to effectively capture nutrients. At one week after planting maize, N2O fluxes of 12.3 g N2O-N ha-1 day-1 from Sesbania plots were about twice as high as those from Acacia, and about seven times the 1.6 g N2O-N ha -1 day-1 from maize monoculture. This was at the time when mineral N was at its peak in the topsoil. The unfertilized maize showed consistently low N2O emissions, which never exceeded 2 g N 2O-N ha-1 day-1 for all the eight sampling dates. The decrease of mineral N concentration in the topsoil resulted in reduced N2O fluxes, despite very high soil moisture conditions. Total N2O-N emissions were greatest for Sesbania plots with 0.3 kg ha -1 lost in 56 days. We conclude that, under high rainfall conditions, there is an inherent problem in managing mineral N originating from mineralization of organic materials as it accumulates at the onset of rains, and is susceptible to leaching before the crop root system develops. We did not quantify nitric oxide and N2 gas emissions, but it is unlikely that total gaseous N losses would be significant and contribute to poor N recovery that has been widely reported.", "keywords": ["2.

Methane fluxes were measured at five sites representing oligotrophic peatlands along a European transect.

The CH4 emissions from the control plots correlated in most cases with the soil temperatures. The depth of the water table, the pH, and the DOC, N and SO4 concentrations were only weakly correlated with the CH4 emissions.

At one site, the CH4 fluxes of the N\uffe2\uff80\uff90treatment plots were significantly lower than those of the control plots. These results were not in agreement with our hypotheses, nor with the results obtained in some earlier studies. However, the results are consistent with the results of the vegetation analyses, which showed no significant treatment effects on species relationships or biomass production.

Biogenic volatile organic compound (BVOC) flux dynamics during the subarctic autumn are largely unexplored and have been considered insignificant due to the relatively low biological activity expected during autumn. Here, we exposed subarctic heath ecosystems to predicted future autumn climate scenarios (ambient, warming, and colder, dark conditions), changes in light availability, and flooding, to mimic the more extreme rainfall or snowmelt events expected in the future. We used climate chambers to measure the net ecosystem fluxes and bidirectional exchange of BVOCs from intact heath mesocosms using a dynamic enclosure technique coupled to a proton\uffe2\uff80\uff90transfer\uffe2\uff80\uff90reaction time\uffe2\uff80\uff90of\uffe2\uff80\uff90flight mass spectrometer (PTR\uffe2\uff80\uff93ToF\uffe2\uff80\uff93MS). We focused on six BVOCs (methanol, acetic acid, acetaldehyde, acetone, isoprene, and monoterpenes) that were among the most dominant and that were previously identified in arctic tundra ecosystems. Warming increased ecosystem respiration and resulted in either net BVOC release or increased uptake compared to the ambient scenario. None of the targeted BVOCs showed net release in the cold and dark scenario. Acetic acid exhibited significantly lower net uptake in the cold and dark scenario than in the ambient scenario, which suggests reduced microbial activity. Flooding was characterized by net uptake of the targeted BVOCs and overruled any temperature effects conferred by the climate scenarios. Monoterpenes were mainly taken up by the mesocosms and their fluxes were not affected by the climate scenarios or flooding. This study shows that although autumn BVOC fluxes on a subarctic heath are generally low, changes in future climate may strongly modify them.

Southeast Asia experiences frequent fires in fuel\uffe2\uff80\uff90rich tropical peatlands, leading to extreme episodes of regional haze with high concentrations of fine particulate matter (PM2.5) impacting human health. In a study published recently, the first field measurements of PM2.5 emission factors for tropical peat fires showed larger emissions than from other fuel types. Here we report even higher PM2.5 emission factors, measured at newly ignited peat fires in Malaysia, suggesting that current estimates of fine particulate emissions from peat fires may be underestimated by a factor of 3 or more. In addition, we use both field and laboratory measurements of burning peat to provide the first mechanistic explanation for the high variability in PM2.5 emission factors, demonstrating that buildup of a surface ash layer causes the emissions of PM2.5 to decrease as the peat fire progresses. This finding implies that peat fires are more hazardous (in terms of aerosol emissions) when first ignited than when still burning many days later. Varying emission factors for PM2.5 also have implications for our ability to correctly model the climate and air quality impacts downwind of the peat fires. For modelers able to implement a time\uffe2\uff80\uff90varying emission factor, we recommend an emission factor for PM2.5 from newly ignited tropical peat fires of 58\uffc2\uffa0g of PM2.5 per kilogram of dry fuel consumed (g/kg), reducing exponentially at a rate of 9%/day. If the age of the fire is unknown or only a single value may be used, we recommend an average value of 24\uffc2\uffa0g/kg.

The Global Carbon Budget 2018 (GCB2018) estimated by the atmospheric CO growth rate, fossil fuel emissions, and modeled (bottom\uffe2\uff80\uff90up) land and ocean fluxes cannot be fully closed, leading to a \uffe2\uff80\uff9cbudget imbalance,\uffe2\uff80\uff9d highlighting uncertainties in GCB components. However, no systematic analysis has been performed on which regions or processes contribute to this term. To obtain deeper insight on the sources of uncertainty in global and regional carbon budgets, we analyzed differences in Net Biome Productivity (NBP) for all possible combinations of bottom\uffe2\uff80\uff90up and top\uffe2\uff80\uff90down data sets in GCB2018: (i) 16 dynamic global vegetation models (DGVMs), and (ii) 5 atmospheric inversions that match the atmospheric CO growth rate. We find that the global mismatch between the two ensembles matches well the GCB2018 budget imbalance, with Brazil, Southeast Asia, and Oceania as the largest contributors. Differences between DGVMs dominate global mismatches, while at regional scale differences between inversions contribute the most to uncertainty. At both global and regional scales, disagreement on NBP interannual variability between the two approaches explains a large fraction of differences. We attribute this mismatch to distinct responses to El\uffc2\uffa0Ni\uffc3\uffb1o\uffe2\uff80\uff93Southern Oscillation variability between DGVMs and inversions and to uncertainties in land use change emissions, especially in South America and Southeast Asia. We identify key needs to reduce uncertainty in carbon budgets: reducing uncertainty in atmospheric inversions (e.g., through more observations in the tropics) and in land use change fluxes, including more land use processes and evaluating land use transitions (e.g., using high\uffe2\uff80\uff90resolution remote\uffe2\uff80\uff90sensing), and, finally, improving tropical hydroecological processes and fire representation within DGVMs.

Observations of the South Polar Residual Cap suggest a possible erosion of the cap, leading to an increase of the global mass of the atmosphere. We test this assumption by making the first comparison between Viking 1 and InSight surface pressure data, which were recorded 40\uffc2\uffa0years apart. Such a comparison also allows us to determine changes in the dynamics of the seasonal ice caps between these two periods. To do so, we first had to recalibrate the InSight pressure data because of their unexpected sensitivity to the sensor temperature. Then, we had to design a procedure to compare distant pressure measurements. We propose two surface pressure interpolation methods at the local and global scale to do the comparison. The comparison of Viking and InSight seasonal surface pressure variations does not show changes larger than \uffc2\uffb18\uffc2\uffa0Pa in the CO2 cycle. Such conclusions are supported by an analysis of Mars Science Laboratory (MSL) pressure data. Further comparisons with images of the south seasonal cap taken by the Viking 2 orbiter and MARCI camera do not display significant changes in the dynamics of this cap over a 40\uffc2\uffa0year period. Only a possible larger extension of the North Cap after the global storm of MY 34 is observed, but the physical mechanisms behind this anomaly are not well determined. Finally, the first comparison of MSL and InSight pressure data suggests a pressure deficit at Gale crater during southern summer, possibly resulting from a large presence of dust suspended within the crater.

Quantifying the responses of the coupled carbon and water cycles to current global warming and rising atmospheric CO2 concentration is crucial for predicting and adapting to climate changes. Here we show that terrestrial carbon uptake (i.e. gross primary production) increased significantly from 1982 to 2011 using a combination of ground-based and remotely sensed land and atmospheric observations. Importantly, we find that the terrestrial carbon uptake increase is not accompanied by a proportional increase in water use (i.e. evapotranspiration) but is largely (about 90%) driven by increased carbon uptake per unit of water use, i.e. water use efficiency. The increased water use efficiency is positively related to rising CO2 concentration and increased canopy leaf area index, and negatively influenced by increased vapour pressure deficits. Our findings suggest that rising atmospheric CO2 concentration has caused a shift in terrestrial water economics of carbon uptake.

The role of trees in the nitrous oxide (N2O) balance of boreal forests has been neglected despite evidence suggesting their substantial contribution. We measured seasonal changes in N2O fluxes from soil and stems of boreal trees in Finland, showing clear seasonality in stem N2O flux following tree physiological activity, particularly processes of CO2 uptake and release. Stem N2O emissions peak during\uffc2\uffa0the vegetation season, decrease rapidly in October, and remain low but significant to the annual totals during winter dormancy. Trees growing on dry soils even turn to consumption of\uffc2\uffa0N2O from the atmosphere during dormancy, thereby reducing their overall N2O emissions. At an\uffc2\uffa0annual scale, pine, spruce and birch are net N2O sources, with spruce being the strongest emitter. Boreal trees thus markedly contribute to the seasonal dynamics of ecosystem N2O exchange, and their species-specific contribution should be included into forest emission inventories.

Globally, inland waters emit over 2 Pg of carbon per year as carbon dioxide, of which the majority originates from streams and rivers. Despite the global significance of fluvial carbon dioxide emissions, little is known about their diel dynamics. Here we present a large-scale assessment of day- and night-time carbon dioxide fluxes at the water-air interface across 34 European streams. We directly measured fluxes four times between October 2016 and July 2017 using drifting chambers. Median fluxes are 1.4 and 2.1\uffe2\uff80\uff89mmol\uffe2\uff80\uff89m\uffe2\uff88\uff922 h\uffe2\uff88\uff921 at midday and midnight, respectively, with night fluxes exceeding those during the day by 39%. We attribute diel carbon dioxide flux variability mainly to changes in the water partial pressure of carbon dioxide. However, no consistent drivers could be identified across sites. Our findings highlight widespread day-night changes in fluvial carbon dioxide fluxes and suggest that the time of day greatly influences measured carbon dioxide fluxes across European streams.Unprecedented nitrogen (N) inputs into terrestrial ecosystems have profoundly altered soil N cycling. Ammonia oxidizers and denitrifiers are the main producers of nitrous oxide (N2O), but it remains unclear how ammonia oxidizer and denitrifier abundances will respond to N loading and whether their responses can predict N\uffe2\uff80\uff90induced changes in soil N2O emission. By synthesizing 101 field studies worldwide, we showed that N loading significantly increased ammonia oxidizer abundance by 107% and denitrifier abundance by 45%. The increases in both ammonia oxidizer and denitrifier abundances were primarily explained by N loading form, and more specifically, organic N loading had stronger effects on their abundances than mineral N loading. Nitrogen loading increased soil N2O emission by 261%, whereas there was no clear relationship between changes in soil N2O emission and shifts in ammonia oxidizer and denitrifier abundances. Our field\uffe2\uff80\uff90based results challenge the laboratory\uffe2\uff80\uff90based hypothesis that increased ammonia oxidizer and denitrifier abundances by N loading would directly cause higher soil N2O emission. Instead, key abiotic factors (mean annual precipitation, soil pH, soil C:N ratio, and ecosystem type) explained N\uffe2\uff80\uff90induced changes in soil N2O emission. Altogether, these findings highlight the need for considering the roles of key abiotic factors in regulating soil N transformations under N loading to better understand the microbially mediated soil N2O emission.Cover crops play an increasingly important role in improving soil quality, reducing agricultural inputs and improving environmental sustainability. The main objectives of this critical global review and systematic analysis were to assess cover crop practices in the context of their impacts on nitrogen leaching, net greenhouse gas balances (NGHGB) and crop productivity. Only studies that investigated the impacts of cover crops and measured one or a combination of nitrogen leaching, soil organic carbon (SOC), nitrous oxide (N2O), grain yield and nitrogen in grain of primary crop, and had a control treatment were included in the analysis. Long\uffe2\uff80\uff90term studies were uncommon, with most data coming from studies lasting 2\uffe2\uff80\uff933\uffc2\uffa0years. The literature search resulted in 106 studies carried out at 372 sites and covering different countries, climatic zones and management. Our analysis demonstrates that cover crops significantly (p\uffc2\uffa0<\uffc2\uffa00.001) decreased N leaching and significantly (p\uffc2\uffa0<\uffc2\uffa00.001) increased SOC sequestration without having significant (p\uffc2\uffa0>\uffc2\uffa00.05) effects on direct N2O emissions. Cover crops could mitigate the NGHGB by 2.06\uffc2\uffa0\uffc2\uffb1\uffc2\uffa02.10\uffc2\uffa0Mg CO2\uffe2\uff80\uff90eq\uffc2\uffa0ha\uffe2\uff88\uff921\uffc2\uffa0year\uffe2\uff88\uff921. One of the potential disadvantages of cover crops identified was the reduction in grain yield of the primary crop by \uffe2\uff89\uff884%, compared to the control treatment. This drawback could be avoided by selecting mixed cover crops with a range of legumes and non\uffe2\uff80\uff90legumes, which increased the yield by \uffe2\uff89\uff8813%. These advantages of cover crops justify their widespread adoption. However, management practices in relation to cover crops will need to be adapted to specific soil, management and regional climatic conditions.

The Water and Nitrogen Management Model (WNMM) was applied to simulate nitrous oxide (N2O) emissions from a wheat-cropped Vertosol under long-term management of no-till, crop residue retention, and nitrogen (N) fertiliser application in southern Queensland, Australia, from July 2006 to June 2009. For the simulation study, eight treatments of combinations of conventional tillage (CT) or no-till (NT), stubble burning (SB) or stubble retention (SR), and N fertiliser application at nil (0N) or 90 (90N) kg N/ha.year were used. The results indicated that WNMM satisfactorily simulated the soil water content of the topsoil, mineral N content of the entire soil profile (0\uffe2\uff80\uff931.5\uffe2\uff80\uff89m), and N2O emissions from the soil under the eight treatments, compared with the corresponding field measurements. For simulating daily N2O emissions from soil, WNMM performed best for the treatment CT-SB-90N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.48, P\uffe2\uff80\uff89<\uffe2\uff80\uff890.001; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff8910.2\uffe2\uff80\uff89g N/ha.day) and worst for the treatment CT-SB-0N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.03, P\uffe2\uff80\uff89=\uffe2\uff80\uff890.174; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff891.2\uffe2\uff80\uff89g N/ha.day). WNMM predicted N2O emissions from the soil more accurately for the fertilised treatments (i.e. 90N v. 0N), and for the residue retained treatments (SR v. SB). To reduce N2O emissions from the no-till and fertilised treatments, three scenarios were examined: application of nitrification inhibitor, application of controlled-release fertiliser, and deep placement of liquid fertiliser (UAN32). Only the deep placement of UAN32 below the 35\uffe2\uff80\uff89cm depth was effective, and could reduce the N2O emissions from the soil by almost 40%.

Smouldering peat fires, the largest fires on Earth in terms of fuel consumption, are reported in six continents and are responsible for regional haze episodes. Haze is the large-scale accumulation of smoke at low altitudes in the atmosphere. It decreases air quality, disrupts transportation and causes health emergencies. Research on peat emissions and haze is modest at best and many key aspects remain poorly understood. Here, we compile an up-to-date inter-study of peat fire emission factors (EFs) found in the literature both from laboratory and from field studies. Tropical peat fires yield larger EFs for the prominent organic compounds than boreal and temperate peat fires, possibly due to the higher fuel carbon content (56.0 vs 44.2%). In contrast, tropical peat fires present slightly lower EFs for particulate matter with diameter \uffe2\uff89\uffa42.5\uffe2\uff80\uff89\uffce\uffbcm (PM2.5) for unknown reasons but are probably related to combustion dynamics. An analysis of the modified combustion efficiency, a parameter widely used for determining the combustion regime of wildfires, shows it is partially misunderstood and highly sensitive to unknown field variables. This is the first review of the literature on smouldering peat emissions. Our integration of the existing literature allows the identification of existing gaps in knowledge and is expected to accelerate progress towards mitigation strategies.

Only few studies have reported on the long-term effects on the more subtle aspects of soil porosity and no reports have considered the potential effects of organic amendments on the pore system in the subsoil. We sampled undisturbed soil cores (100 cm3 and 6280 cm3) in metal cylinders in differently fertilized plots in the long-term field experiments at Askov Experimental Station, Denmark. We selected the 0-60 cm soil layer of plots dressed for a century with either mineral fertilizers (labelled NPK) or animal manure (labelled AM). Both fertilization treatments were studied at two levels of nutrient application: 'normal' (labelled '1') and 1.5 times 'normal' (labelled '11/2'). Plots unfertilized for a century (labelled UNF) were included as a reference for some of the studies. Water retention, air permeability and air diffusivity were measured on the small cores, and we used the large cores for measuring near-saturated and saturated hydraulic conductivity. In the plough layer, the AM and NPK soils displayed identical pore volumes in size fractions larger as well as smaller than 30 micrometer, while the UNF soil had a significantly smaller volume of pores <30 micrometer. No clear trends were found in treatment effects on pore organization calculated from air diffusivity and air permeability measurements. No significant differences in hydraulic conductivity were found for plough layer soil. For the soil below ploughing depth, significantly larger macropore volumes and near-saturated hydraulic conductivities were found for soil receiving the higher ('11/2') amount of nutrients compared with the 'normally' dressed soil. This effect was independent of fertilization system (AM or NPK). We attribute the larger volume of macropores to the improved root growth conditions in the soil with the larger nutrient level. We conclude that addition of animal manure in rates realistic in agriculture has only a modest effect on soil pore characteristics of the plough layer soil compared with the use of mineral fertilizers. For the soil below ploughing depth, a high level of nutrient application rather than the use of animal manure may increase soil macroporosity and near-saturated hydraulic conductivity.", "keywords": ["2.

There is a clear need for transformative change in the land management and food production sectors to address the global land challenges of climate change mitigation, climate change adaptation, combatting land degradation and desertification, and delivering food security (referred to hereafter as \uffe2\uff80\uff9cland challenges\uffe2\uff80\uff9d). We assess the potential for 40 practices to address these land challenges and find that: Nine options deliver medium to large benefits for all four land challenges. A further two options have no global estimates for adaptation, but have medium to large benefits for all other land challenges. Five options have large mitigation potential (>3\uffc2\uffa0Gt CO2eq/year) without adverse impacts on the other land challenges. Five options have moderate mitigation potential, with no adverse impacts on the other land challenges. Sixteen practices have large adaptation potential (>25 million people benefit), without adverse side effects on other land challenges. Most practices can be applied without competing for available land. However, seven options could result in competition for land. A large number of practices do not require dedicated land, including several land management options, all value chain options, and all risk management options. Four options could greatly increase competition for land if applied at a large scale, though the impact is scale and context specific, highlighting the need for safeguards to ensure that expansion of land for mitigation does not impact natural systems and food security. A number of practices, such as increased food productivity, dietary change and reduced food loss and waste, can reduce demand for land conversion, thereby potentially freeing\uffe2\uff80\uff90up land and creating opportunities for enhanced implementation of other practices, making them important components of portfolios of practices to address the combined land challenges.Bioenergy crops are often classified (and subsequently regulated) according to species that have been evaluated as environmentally beneficial or detrimental, but in practice, management decisions rather than species per se can determine the overall environmental impact of a bioenergy production system. Here, we review the greenhouse gas balance and \uffe2\uff80\uff98management swing potential\uffe2\uff80\uff99 of seven different bioenergy cropping systems in temperate and tropical regions. Prior land use, harvesting techniques, harvest timing, and fertilization are among the key management considerations that can swing the greenhouse gas balance of bioenergy from positive to negative or the reverse. Although the management swing potential is substantial for many cropping systems, there are some species (e.g., soybean) that have such low bioenergy yield potentials that the environmental impact is unlikely to be reversed by management. High\uffe2\uff80\uff90yielding bioenergy crops (e.g., corn, sugarcane, Miscanthus, and fast\uffe2\uff80\uff90growing tree species), however, can be managed for environmental benefits or losses, suggesting that the bioenergy sector would be better informed by incorporating management\uffe2\uff80\uff90based evaluations into classifications of bioenergy feedstocks.

Biomass\uffe2\uff80\uff90derived black carbon (biochar) is considered to be an effective tool to mitigate global warming by long\uffe2\uff80\uff90term C\uffe2\uff80\uff90sequestration in soil and to influence C\uffe2\uff80\uff90mineralization via priming effects. However, the underlying mechanism of biochar (BC) priming relative to conventional biowaste (BW) amendments remains uncertain. Here, we used a stable carbon isotope (\uffce\uffb413C) approach to estimate the possible biochar effects on native soil C\uffe2\uff80\uff90mineralization compared with various BW additions and potential carbon sequestration. The results show that immediately after application, BC suppresses and then increases C\uffe2\uff80\uff90mineralization, causing a loss of 0.14\uffe2\uff80\uff937.17\uffc2\uffa0mg\uffe2\uff80\uff90CO2\uffe2\uff80\uff93C\uffc2\uffa0g\uffe2\uff88\uff921\uffe2\uff80\uff90C compared to the control (0.24\uffe2\uff80\uff931.86\uffc2\uffa0mg\uffe2\uff80\uff90CO2\uffe2\uff80\uff93C\uffc2\uffa0g\uffe2\uff88\uff921\uffe2\uff80\uff90C) over 1\uffe2\uff80\uff93120\uffc2\uffa0days. Negative priming was observed for BC compared to various BW amendments (\uffe2\uff88\uff9210.22 to \uffe2\uff88\uff9223.56\uffc2\uffa0mg\uffe2\uff80\uff90CO2\uffe2\uff80\uff93C\uffc2\uffa0g\uffe2\uff88\uff921\uffe2\uff80\uff90soil\uffe2\uff80\uff90C); however, it was trivially positive relative to that of the control (8.64\uffc2\uffa0mg\uffe2\uff80\uff90CO2\uffe2\uff80\uff93C\uffc2\uffa0g\uffe2\uff88\uff921\uffe2\uff80\uff90soil\uffe2\uff80\uff90C). Furthermore, according to the residual carbon and \uffce\uffb413C signature of postexperimental soil carbon, BC\uffe2\uff80\uff90C significantly increased (P\uffc2\uffa0<\uffc2\uffa00.05) the soil carbon stock by carbon sequestration in soil compared with various biowaste amendments. The results of cumulative CO2\uffe2\uff80\uff93C emissions, relative priming effects, and carbon storage indicate that BC reduces C\uffe2\uff80\uff90mineralization, resulting in greater C\uffe2\uff80\uff90sequestration compared with other BW amendments, and the magnitude of this effect initially increases and then decreases and stabilizes over time, possibly due to the presence of recalcitrant\uffe2\uff80\uff90C (4.92\uffc2\uffa0mg\uffe2\uff80\uff90C\uffc2\uffa0g\uffe2\uff88\uff921\uffe2\uff80\uff90soil) in BC, the reduced microbial activity, and the sorption of labile organic carbon (OC) onto BC particles.

Nonetheless, our understanding of nutrient controls remains far from complete and poorly quantified, at least partly due to a lack of informative, comparable, and accessible datasets at regional-to-global scales. A growing research infrastructure of multi-site networks are providing valuable data on C fluxes and stocks and are monitoring their responses to global environmental change and measuring responses to experimental treatments. These networks thus provide an opportunity for improving our understanding of C-nutrient cycle interactions and our ability to model them. However, coherent information on how nutrient cycling interacts with observed C cycle patterns is still generally lacking. Here, we argue that complementing available C-cycle measurements from monitoring and experimental sites with data characterizing nutrient availability will greatly enhance their power and will improve our capacity to forecast future trajectories of terrestrial C cycling and climate. Therefore, we propose a set of complementary measurements that are relatively easy to conduct routinely at any site or experiment and that, in combination with C cycle observations, can provide a robust characterization of the effects of nutrient availability across sites. In addition, we discuss the power of different observable variables for informing the formulation of models and constraining their predictions. Most widely available measurements of nutrient availability often do not align well with current modelling needs. This highlights the importance to foster the interaction between the empirical and modelling communities for setting future research priorities.", "keywords": ["Global vegetation models", "550", "manipulation experiments", "Terrestrial-Aquatic Linkages", "Kolefni", "01 natural sciences", "Nutrient cycle", "Agricultural and Biological Sciences", "Terrestrial ecosystem", "SDG 13 - Climate Action", "Climate change", "Jar\u00f0vegur", "Environmental resource management", "Global change", "General Environmental Science", "SDG 15 - Life on Land", "Carbon-nutrient cycle interactions", "2.

Permafrost thaw exposes previously frozen organic carbon (OC) to microbial decomposition with subsequent emission of the greenhouse gases carbon dioxide (CO2) and methane (CH4) into the atmosphere, creating positive feedback on global warming, i.e. the permafrost carbon feedback (Schuur et al 2015). Permafrost contains 1460\u20131600 GtC, almost twice the C in the atmosphere (IPCC 2019), and 15 \u00b1 3% of that OC stock could be emitted as greenhouse gases by 2100 (Schuur et al 2015).

Abstract. Boreal forest soils are globally an important sink for methane (CH4), while these soils are also capable of emitting CH4 under favourable conditions. Soil wetness is a well-known driver of CH4 flux, and the wetness can be estimated with several terrain indices developed for the purpose. The aim of this study was to quantify the spatial variability of the forest floor CH4 flux with a topography-based upscaling method connecting the flux with its driving factors. We conducted spatially extensive forest floor CH4 flux and soil moisture measurements, complemented by ground vegetation classification, in a boreal pine forest. We then modelled the soil moisture with a random forest model using digital-elevation-model-derived topographic indices, based on which we upscaled the forest floor CH4 flux. The modelling was performed for two seasons: May\uffe2\uff80\uff93July and August\uffe2\uff80\uff93October. Additionally, we evaluated the number of flux measurement points needed to get an accurate estimate of the flux at the whole study site merely by averaging. Our results demonstrate high spatial heterogeneity in the forest floor CH4 flux resulting from the soil moisture variability as well as from the related ground vegetation. The mean measured CH4 flux at the sample points was \uffe2\uff88\uff925.07\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in May\uffe2\uff80\uff93July and \uffe2\uff88\uff928.67\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in August\uffe2\uff80\uff93October, while the modelled flux for the whole area was \uffe2\uff88\uff927.42 and \uffe2\uff88\uff929.91\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 for the two seasons, respectively. The spatial variability in the soil moisture and consequently in the CH4 flux was higher in the early summer (modelled range from \uffe2\uff88\uff9212.3 to 6.19\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921) compared to the autumn period (range from \uffe2\uff88\uff9214.6 to \uffe2\uff88\uff922.12\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921), and overall the CH4 uptake rate was higher in autumn compared to early summer. In the early summer there were patches emitting high amounts of CH4; however, these wet patches got drier and smaller in size towards the autumn, changing their dynamics to CH4 uptake. The mean values of the measured and modelled CH4 fluxes for the sample point locations were similar, indicating that the model was able to reproduce the results. For the whole site, upscaling predicted stronger CH4 uptake compared to simply averaging over the sample points. The results highlight the small-scale spatial variability of the boreal forest floor CH4 flux and the importance of soil chamber placement in order to obtain spatially representative CH4 flux results. To predict the CH4 fluxes over large areas more reliably, the locations of the sample points should be selected based on the spatial variability of the driving parameters, in addition to linking the measured fluxes with the parameters.

Residual expressions of enteric emissions favor a more equitable identification of an animal\uffe2\uff80\uff99s methanogenic potential compared with traditional measures of enteric emissions. The objective of this study was to investigate the effect of divergently ranking beef cattle for residual methane emissions (RME) on animal productivity, enteric emissions, and rumen fermentation. Dry matter intake (DMI), growth, feed efficiency, carcass output, and enteric emissions (GreenFeed emissions monitoring system) were recorded on 294 crossbred beef cattle (steers = 135 and heifers = 159; mean age 441 d (SD = 49); initial body weight (BW) of 476 kg (SD = 67)) at the Irish national beef cattle performance test center. Animals were offered a total mixed ration (77% concentrate and 23% forage; 12.6 MJ ME/kg of DM and 12% CP) ad libitum with emissions estimated for 21 d over a mean feed intake measurement period of 91 d. Animals had a mean daily methane emissions (DME) of 229.18 g/d (SD = 45.96), methane yield (MY) of 22.07 g/kg of DMI (SD = 4.06), methane intensity (MI) 0.70 g/kg of carcass weight (SD = 0.15), and RME 0.00 g/d (SD = 0.34). RME was computed as the residuals from a multiple regression model regressing DME on DMI and BW (R2 = 0.45). Animals were ranked into three groups namely high RME (&gt;0.5 SD above the mean), medium RME (\uffc2\uffb10.5 SD above/below the mean), and low RME (&gt;0.5 SD below the mean). Low RME animals produced 17.6% and 30.4% less (P &lt; 0.05) DME compared with medium and high RME animals, respectively. A ~30% reduction in MY and MI was detected in low versus high RME animals. Positive correlations were apparent among all methane traits with RME most highly associated with (r = 0.86) DME. MY and MI were correlated (P &lt; 0.05) with DMI, growth, feed efficiency, and carcass output. High RME had lower (P &lt; 0.05) ruminal propionate compared with low RME animals and increased (P &lt; 0.05) butyrate compared with medium and low RME animals. Propionate was negatively associated (P &lt; 0.05) with all methane traits. Greater acetate:propionate ratio was associated with higher RME (r = 0.18; P &lt; 0.05). Under the ad libitum feeding regime deployed here, RME was the best predictor of DME and only methane trait independent of animal productivity.

Targets for bioenergy have been set worldwide to mitigate climate change. Although feedstock sources are often ambiguous, pledges in European nations, the United States and Brazil amount to more than 100 Mtoe of biorenewable fuel production by 2020. As a consequence, the biofuel sector is developing rapidly, and it is increasingly important to distinguish bioenergy options that can address energy security and greenhouse gas mitigation from those that cannot. This paper evaluates how bioenergy production affects land-use change (LUC), and to what extent land-use modelling can inform sound decision-making. We identified local and global internalities and externalities of biofuel development scenarios, reviewed relevant data sources and modelling approaches, identified sources of controversy about indirect LUC (iLUC) and then suggested a framework for comprehensive assessments of bioenergy. Ultimately, plant biomass must be managed to produce energy in a way that is consistent with the management of food, feed, fibre, timber and environmental services. Bioenergy production provides opportunities for improved energy security, climate mitigation and rural development, but the environmental and social consequences depend on feedstock choices and geographical location. The most desirable solutions for bioenergy production will include policies that incentivize regionally integrated management of diverse resources with low inputs, high yields, co-products, multiple benefits and minimal risks of iLUC. Many integrated assessment models include energy resources, trade, technological development and regional environmental conditions, but do not account for biodiversity and lack detailed data on the location of degraded and underproductive lands that would be ideal for bioenergy production. Specific practices that would maximize the benefits of bioenergy production regionally need to be identified before a global analysis of bioenergy-related LUC can be accomplished.

This paper aims to perform a meta\uffe2\uff80\uff90analysis of the literature comparing the environmental impacts of organic and conventional farming and linking these to differences in management practises. The studied environmental impacts are related to land use efficiency, organic matter content in the soil, nitrate and phosphate leaching to the water system, greenhouse gas emissions and biodiversity.

Design/methodology/approach

The theoretic framework uses the driver\uffe2\uff80\uff90state\uffe2\uff80\uff90response framework and literature data were analysed using meta\uffe2\uff80\uff90analysis methodology. Meta\uffe2\uff80\uff90analysis is the statistical analysis of multiple study results. Data were obtained by screening peer reviewed literature.

Findings

From the paper's meta\uffe2\uff80\uff90analysis it can conclude that soils in organic farming systems have on average a higher content of organic matter. It can also conclude that organic farming contributes positively to agro\uffe2\uff80\uff90biodiversity (breeds used by the farmers) and natural biodiversity (wild life). Concerning the impact of the organic farming system on nitrate and phosphorous leaching and greenhouse gas emissions the result of the analysis is not that straightforward. When expressed per production area organic farming scores better than conventional farming for these items. However, given the lower land use efficiency of organic farming in developed countries, this positive effect expressed per unit product is less pronounced or not present at all.

Original value

Given the recent growth of organic farming and the general perception that organic farming is more environment friendly than its conventional counterpart, it is interesting to explore whether it meets the alleged benefits. By combining several studies in one analysis, the technique of meta\uffe2\uff80\uff90analysis is powerful and may allow the generation of more nuanced findings and the generalisation of those findings.

1.\uffe2\uff80\uff82The Amazon region may experience increasing moisture limitation over this century. Leaf dark respiration (R) is a key component of the Amazon rain forest carbon (C) cycle, but relatively little is known about its sensitivity to drought.

2.\uffe2\uff80\uff82Here, we present measurements of R standardized to 25\uffe2\uff80\uff83\uffc2\uffb0C and leaf morphology from different canopy heights over 5\uffe2\uff80\uff83years at a rain forest subject to a large\uffe2\uff80\uff90scale through\uffe2\uff80\uff90fall reduction (TFR) experiment, and nearby, unmodified Control forest, at the Caxiuan\uffc3\uffa3 reserve in the eastern Amazon.

3.\uffe2\uff80\uff82In all five post\uffe2\uff80\uff90treatment measurement campaigns, mean R at 25\uffe2\uff80\uff83\uffc2\uffb0C was elevated in the TFR forest compared to the Control forest experiencing normal rainfall. After 5\uffe2\uff80\uff83years of the TFR treatment, R per unit leaf area and mass had increased by 65% and 42%, respectively, relative to pre\uffe2\uff80\uff90treatment means. In contrast, leaf area index (L) in the TFR forest was consistently lower than the Control, falling by 23% compared to the pre\uffe2\uff80\uff90treatment mean, largely because of a decline in specific leaf area (S).

4.\uffe2\uff80\uff82The consistent and significant effects of the TFR treatment on R, L and S suggest that severe drought events in the Amazon, of the kind that may occur more frequently in future, could cause a substantial increase in canopy carbon dioxide emissions from this ecosystem to the atmosphere.

Shoot\uffe2\uff80\uff90level emissions of aerobically produced methane (CH4) may be an overlooked source of tree\uffe2\uff80\uff90derived CH4, but insufficient understanding of the interactions between their environmental and physiological drivers still prevents the reliable upscaling of canopy CH4 fluxes.

We utilised a novel automated chamber system to continuously measure CH4 fluxes from the shoots of Pinus sylvestris (Scots pine) saplings under drought to investigate how canopy CH4 fluxes respond to the drought\uffe2\uff80\uff90induced alterations in their physiological processes and to isolate the shoot\uffe2\uff80\uff90level production of CH4 from soil\uffe2\uff80\uff90derived transport and photosynthesis.

We found that aerobic CH4 emissions are not affected by the drought\uffe2\uff80\uff90induced stress, changes in physiological processes, or decrease in photosynthesis. Instead, these emissions vary on short temporal scales with environmental drivers such as temperature, suggesting that they result from abiotic degradation of plant compounds.

Our study shows that aerobic CH4 emissions from foliage are distinct from photosynthesis\uffe2\uff80\uff90related processes. Thus, instead of photosynthesis rates, it is more reliable to construct regional and global estimates for the aerobic CH4 emission based on regional differences in foliage biomass and climate, also accounting for short\uffe2\uff80\uff90term variations of weather variables such as air temperature and solar radiation.

Recent studies have shown that stem fluxes, although highly variable among trees, can alter the strength of the methane (CH4) sink or nitrous oxide (N2O) source in some forests, but the patterns and magnitudes of these fluxes remain unclear. This study investigated the drivers of subdaily and seasonal variations in stem and soil CH4, N2O and carbon dioxide (CO2) fluxes.

CH4, N2O and CO2 fluxes were measured continuously for 19\uffe2\uff80\uff89months in individual stems of two tree species, Eperua falcata (Aubl.) and Lecythis poiteaui (O. Berg), and surrounding soils using an automated chamber system in an upland tropical forest. Subdaily variations in these fluxes were related to environmental and stem physiological (sap flow and stem diameter variations) measurements under contrasting soil water conditions.

The results showed that physiological and climatic drivers only partially explained the subdaily flux variations. Stem CH4 and CO2 emissions and N2O uptake varied with soil water content, time of day and between individuals. Stem fluxes decoupled from soil fluxes.

Our study contributes to understanding the regulation of stem greenhouse gas fluxes. It suggests that additional variables (e.g. internal gas concentrations, wood\uffe2\uff80\uff90colonising microorganisms, wood density and anatomy) may account for the remaining unexplained variability in stem fluxes, highlighting the need for further studies.

Long\uffe2\uff80\uff90term effects of elevated atmospheric CO2 on the ammonia\uffe2\uff80\uff90oxidizing and denitrifying bacteria in a grassland soil were investigated to test whether a shift in abundance of these N\uffe2\uff80\uff90cycling microorganisms was responsible for enhanced N2O emissions under elevated atmospheric CO2. Soil samples (7.5\uffc2\uffa0cm increments to 45\uffc2\uffa0cm depth) were collected in 2008 from the University of Giessen Free Air Carbon dioxide Enrichment (GiFACE), a permanent grassland exposed to moderately elevated atmospheric CO2 (+20%) since 1998. GiFACE plots lay on a soil moisture gradient because of gradually changing depth to the underlying water table and labeled as the DRY block (furthest from water table), MED block (intermediate to water table), and WET block (nearest to water table). Mean N2O emissions measured since 1998 have been significantly higher under elevated CO2. This study sought to identify microbial and biochemical parameters that might explain higher N2O emissions under elevated CO2. Soil biochemical parameters [extractable organic carbon (EOC), dissolved organic nitrogen (DON), NH4+, NO3\uffe2\uff88\uff92], and abundances of genes encoding the key enzymes involved in ammonia oxidation (amoA) and denitrification (nirK, nirS, nosZ) depended more on soil depth and block (underlying soil moisture gradient) than on elevated CO2. Ammonia oxidation and denitrification gene abundances, relative abundances (ratios) of nirS to nirK, of nosZ to both nirS and to nirK, and of the measured soil biochemical properties DON and NO3\uffe2\uff88\uff92 tended to be lower in elevated CO2 plots as compared with ambient plots in the MED and WET blocks while the DRY block exhibited an opposite trend. High N2O emissions under elevated CO2 in the MED and WET blocks correlated with lower nosZ to nirK ratios, suggesting that increased N2O emissions under elevated CO2 might be caused by a higher proportion of N2O\uffe2\uff80\uff90producing rather than N2O consuming (N2 producing) denitrifiers.

Growing bioenergy crops such as Miscanthus has the potential to mitigate atmospheric carbon dioxide emissions by the replacement of fossil fuels and by storing carbon (C) in the soil due to land use change. Here we compare direct measurements of soil organic C fractions made in Carlow (Ireland) to model predictions made by RothC and a cohort model. Our results show that when Miscanthus is grown on land previously under arable agriculture, the soil organic C will increase to a level above that of native pasture, as Miscanthus organic material is shown to have a slow decomposition rate. In addition we demonstrate that for measured organic C, fractions of different lability are similar to the C pools used in RothC. Using the model predictions from RothC and Miscanthus yields from MISCANFOR, we predict that in Ireland, changing the land use from arable to Miscanthus plantations has the potential to store between 2 and 3\uffe2\uff80\uff83Mg\uffe2\uff80\uff83C\uffe2\uff80\uff83ha\uffe2\uff88\uff921\uffe2\uff80\uff83y\uffe2\uff88\uff921 depending on the crop yield and the initial soil organic C level.

One way of reducing the emissions of fossil fuel\uffe2\uff80\uff90derived carbon dioxide (CO2) is to replace fossil fuels with biofuels produced from agricultural biomasses or residuals. However, cultivation of soils results in emission of other greenhouse gases (GHGs), especially nitrous oxide (N2O). Previous studies on biofuel production systems showed that emissions of N2O may counterbalance a substantial part of the global warming reduction, which is achieved by fossil fuel displacement. In this study, we related measured field emissions of N2O to the reduction in fossil fuel\uffe2\uff80\uff90derived CO2, which was obtained when agricultural biomasses were used for biofuel production. The analysis included five organically managed feedstocks (viz. dried straw of sole cropped rye, sole cropped vetch and intercropped rye\uffe2\uff80\uff93vetch, as well as fresh grass\uffe2\uff80\uff93clover and whole crop maize) and three scenarios for conversion of biomass into biofuel. The scenarios were (i) bioethanol, (ii) biogas and (iii) coproduction of bioethanol and biogas. In the last scenario, the biomass was first used for bioethanol fermentation and subsequently the effluent from this process was utilized for biogas production. The net GHG reduction was calculated as the avoided fossil fuel\uffe2\uff80\uff90derived CO2, where the N2O emission was subtracted. This value did not account for fossil fuel\uffe2\uff80\uff90derived CO2 emissions from farm machinery and during conversion processes that turn biomass into biofuel. The greatest net GHG reduction, corresponding to 700\uffe2\uff80\uff93800\uffc2\uffa0g\uffc2\uffa0CO2\uffc2\uffa0m\uffe2\uff88\uff922, was obtained by biogas production or coproduction of bioethanol and biogas on either fresh grass\uffe2\uff80\uff93clover or whole crop maize. In contrast, biofuel production based on lignocellulosic crop residues (i.e. rye and vetch straw) provided considerably lower net GHG reductions (\uffe2\uff89\uffa4215\uffc2\uffa0g\uffc2\uffa0CO2\uffc2\uffa0m\uffe2\uff88\uff922), and even negative numbers sometimes. No GHG benefit was achieved by fertilizing the maize crop because the extra crop yield, and thereby increased biofuel production, was offset by enhanced N2O emissions.

The expansion of biofuel production can lead to an array of negative environmental impacts. Therefore, the European Union (EU) has recently imposed sustainability criteria on biofuel production in the Renewable Energy Directive (RED). In this article, we analyse the effectiveness of the sustainability criteria for climate change mitigation and biodiversity conservation. We first use a global agriculture and forestry model to investigate environmental effects of the EU member states National Renewable Energy Action Plans (NREAPs) without sustainability criteria. We conclude that these targets would drive losses of 2.2\uffc2\uffa0Mha of highly biodiverse areas and generate 95\uffc2\uffa0Mt\uffc2\uffa0CO 2 eq of additional greenhouse gas (GHG) emissions. However, in a second step, we demonstrate that the EU biofuel demand could be satisfied \uffe2\uff80\uff98sustainably\uffe2\uff80\uff99 according to RED despite its negative environmental effects. This is because the majority of global crop production is produced \uffe2\uff80\uff98sustainably\uffe2\uff80\uff99 in the sense of RED and can provide more than 10 times the total European biofuel demand in 2020 if reallocated from sectors without sustainability criteria. This finding points to a potential policy failure of applying sustainability regulation to a single sector in a single region. To be effective this policy needs to be more complete in targeting a wider scope of agricultural commodities and more comprehensive in its membership of countries.

Tree stems from wetland, floodplain and upland forests can produce and emit methane (CH4). Tree CH4 stem emissions have high spatial and temporal variability, but there is no consensus on the biophysical mechanisms that drive stem CH4 production and emissions. Here, we summarize up to 30 opportunities and challenges for stem CH4 emissions research, which, when addressed, will improve estimates of the magnitudes, patterns and drivers of CH4 emissions and trace their potential origin. We identified the need: (1) for both long\uffe2\uff80\uff90term, high\uffe2\uff80\uff90frequency measurements of stem CH4 emissions to understand the fine\uffe2\uff80\uff90scale processes, alongside rapid large\uffe2\uff80\uff90scale measurements designed to understand the variability across individuals, species and ecosystems; (2) to identify microorganisms and biogeochemical pathways associated with CH4 production; and (3) to develop a mechanistic model including passive and active transport of CH4 from the soil\uffe2\uff80\uff93tree\uffe2\uff80\uff93atmosphere continuum. Addressing these challenges will help to constrain the magnitudes and patterns of CH4 emissions, and allow for the integration of pathways and mechanisms of CH4 production and emissions into process\uffe2\uff80\uff90based models. These advances will facilitate the upscaling of stem CH4 emissions to the ecosystem level and quantify the role of stem CH4 emissions for the local to global CH4 budget.

Plants are recognized as sources of aerobically produced methane (CH4), but the seasonality, environmental drivers and significance of CH4 emissions from the canopies of evergreen boreal trees remain poorly understood.

We measured the CH4 fluxes from the shoots of Pinus sylvestris (Scots pine) and Picea abies (Norway spruce) saplings in a static, non\uffe2\uff80\uff90steady\uffe2\uff80\uff90state chamber setup to investigate if the shoots of boreal conifers are a source of CH4 during spring.

We found that the shoots of Scots pine emitted CH4 and these emissions correlated with the photosynthetically active radiation. For Norway spruce, the evidence for CH4 emissions from the shoots was inconclusive.

Our study shows that the canopies of evergreen boreal trees are a potential source of CH4 in the spring and that these emissions are driven by a temperature\uffe2\uff80\uff90by\uffe2\uff80\uff90light interaction effect of solar radiation either directly or indirectly through its effects on tree physiological processes.

The indirect land use change (ILUC) effect of biofuels has called into question the greenhouse gas (GHG) mitigation benefit of biofuels compared with that of fossil fuels. This article reviews the various economic modeling approaches being used to assess the ILUC effect and discusses the key factors that influence estimates of its magnitude. We find that there is considerable variability in the magnitude of ILUC associated with a biofuel pathway across studies and within a study, depending on underlying model parameters. These estimates are sensitive to the scale of biofuel production, the mix of policies and biofuels considered, variations in the parametric assumptions that govern price transmission through international trade, and the ease of changes in land use at the intensive and extensive margins. We discuss the challenges in implementing policies to address ILUC.

Maize is a major irrigated crop in Mediterranean areas and its typical intensive management may impact soil nitrous oxide (N2O) emissions. In these irrigated continuous maize systems, the legumes incorporation as well as adjusted nitrogen (N) fertilization might be interesting strategies to reduce soil N2O emissions. The objective of this study was to assess the impact of cropping diversification and different N rates on soil N2O emissions in flooded irrigated maize under Mediterranean conditions. To achieve this, two cropping systems (maize monoculture system, MC; and pea -maize rotation, MP) and 3N rates (unfertilized, 0N; medium rate, MN; and high rate, HN) were evaluated in a field experiment established in NE Spain during 2\uffc2\uffa0years (2019; 2020). During the studied period, the N rate had a significant effect on soil N2O emissions, with a non-linear positive response of cumulative soil N2O emissions to N rates. In both systems, quick and high increases of soil N2O fluxes were observed immediately after the N application reaching 55 and 100\uffc2\uffa0mg N2O-N m\uffe2\uff88\uff922\uffc2\uffa0day\uffe2\uff88\uff921 in MC and MP, respectively. Both years, the pea phase of the MP rotation showed greater cumulative N2O emissions than the fallow of MC. However, N2O losses in the maize phase were similar (2019) or even higher (2020) in MC than in MP. Moreover, in both seasons, the MN treatments showed lower yield-scaled N2O emissions and N emission factor than the HN treatments, being this last lower than 1% in all cases. The results obtained showed that in irrigated Mediterranean conditions the replacement of a fallow by a legume, together with an adjusted N fertilization are favourable strategies to mitigate soil N2O emissions in high-yielding maize systems.
