It also includes the R script to reproduce these layers and their uncertainties. <em><strong>Investible Forest Carbon</strong>: </em>The investible forest carbon map was produced based on the total volume of CO<sub>2</sub>e associated with the three main carbon pools in the tropics, namely aboveground carbon, belowground carbon and soil organic carbon. This is followed by the application of key Verified Carbon Standard (VCS) criteria including additionality, to determine the magnitude and areas of investible forest carbon across the tropics. <em>Aboveground carbon.</em> A stoichiometric factor of 0.475 was applied to recent spatial data on aboveground carbon biomass to obtain carbon stock based on established carbon accounting methodologies. An uncertainty analyses was also performed to account for potential variability in stoichiometric factor. Subsequently, a conversion factor of 3.67 was applied to the carbon stock layer to obtain the volume of CO<sub>2</sub>e associated with this carbon pool. <em>Belowground carbon</em>. Belowground carbon biomass was firstly derived by applying two allometric equations relating to root to shoot biomass to the most recent spatial dataset on aboveground carbon biomass following established carbon accounting methodologies. The two equations are: Belowground biomass = 0.489\u00d7aboveground biomass^0.89; and Belowground biomass = 0.26\u00d7aboveground biomass A stoichiometric factor of 0.475 was subsequently applied to the estimated belowground carbon biomass to obtain the carbon stock. An uncertainty analyses was then performed to determine the mean, minimum and maximum values for belowground carbon. Following that, a conversion factor of 3.67 was applied to the carbon stock layer to obtain the volume of CO<sub>2</sub>e associated with this carbon pool. <em>Soil Organic Carbon</em>. Organic carbon density of the topsoil layer (0-30 cm) was obtained from the European Soil Data Centre as it represented the best data available for soil organic carbon. A conversion factor of 3.67 was subsequently applied to derive the volume of CO<sub>2</sub>e associated with this carbon pool. <em>Applying VCS criteria</em>. The criterion of additionality is a pre-condition for carbon credits to be certified under the VCS. This implies that only the volume of forest carbon that are under imminent threat of decline or loss if left unprotected by a conservation intervention can be certified under the VCS. The volume of forest carbon under threat of loss was based on the best available data on predicted deforestation rates across the tropics (through to the year 2029), and annualized over predicted 15-year period. The estimated annual deforestation rates was then applied to the total volume of CO<sub>2</sub>e associated with tropical forests as estimated above, deriving the volume of CO<sub>2</sub>e that would be certifiable and thus investible under the VCS. In addition, a conservative 10-year decay estimate was assumed for the estimate of the belowground carbon pool, and lands that will likely not be certifiable for other reasons, including recently deforested areas (i.e. for the period of 2010-2017), a well as human settlements, were excluded. Lastly, the VCS requirement to set aside buffer credits of 20% was accounted for to consider the risk of non-permanence associated with Agriculture, Forestry and Other Land Use (AFOLU) projects. <strong><em>Return</em>-<em>on-Investment</em></strong>. From the investible forest carbon map, the relative profitability of these areas was then modelled to produce a global forest carbon return-on-investment map based on their NPV. The NPV of returns were based on several simplifying assumptions following established values from previous studies. <em>Cost of project establishment</em>. The cost of project establishment was estimated to be at $25 ha<sup>-1</sup>. This was based on a range of costs that are key to the development of a project, including but not limited to project design, governance and planning, enforcement, zonation, land tenure and acquisition, surveying and research. <em>Cost for annual maintenance</em>. The cost for annual maintenance was estimated to be $10 ha<sup>-1</sup>, which included aspects such as in education and communication, monitoring, sustainable livelihoods, marketing, finance and administration. <em>Carbon price</em>. A constant carbon price of $5.8 t<sup>-1</sup>CO\u00ad<sub>2</sub>e for the first five years was applied. This price was based on an average price of carbon for avoided deforestation projects reported recently by Forest Trends\u2019 Ecosystem Marketplace (i.e. for the period 2006 \u2013 2018). Subsequently, a 5% price appreciation was applied annually over a project timeframe of 30 years. <em>Discount rate</em>. We calculated NPV of annual and accumulated profits over 30 years based on a 10% risk-adjusted discount rate. Further details for these datasets and their uncertainties are presented in Koh et. al.

Climate change is predicted to increase the frequency of drought events, with uncertain consequences for soil microbial communities. In this study we tested the hypothesis that agricultural management used to enhance soil carbon stocks would increase the stability of microbial community structure and activity in response to water-stress. Soil was sampled from a long-term field trial with three soil carbon management systems and was used in a laboratory study of the effect of a dry\u2013wet cycle on organic C mineralisation and microbial community structure. After a drying\u2013rewetting event, soil microcosms were maintained wet and microbial community structure and abundance as well as microbial respiration were measured for four weeks. The results showed that the NO-TILL management system, with the highest soil organic matter content and respiration rate, had a distinct bacterial community structure relative to the conventional and the TILL without fertiliser systems. In all management systems, the rewetting event clearly modified microbial community structure and activity. Both returned to their pre-drought state after 28 days. However, the magnitude of variation of C mineralisation was lower (i.e. the resistance to stress was higher) in the NO-TILL system. The genetic structure of the NO-TILL bacterial communities was most modified by water-stress and exhibited a slower recovery rate. This suggests that land use management can increase microbial functional resistance to drought stress via the establishment of bacterial communities with particular metabolic capacities. Nevertheless, the resilience rates of C mineralisation were similar among management regimes, suggesting that similar mechanisms occur, maybe due to a common soil microbial community legacy.", "keywords": ["[SDE] Environmental Sciences", "570", "Agricultural land use", "[SDV]Life Sciences [q-bio]", "630", "Drying-rewetting", "FUNCTIONAL STABILITY", "[SDV.BV]Life Sciences [q-bio]/Vegetal Biology", "[SDV.BV] Life Sciences [q-bio]/Vegetal Biology", "Drying\u2013rewetting", "NITROGEN MINERALIZATION", "Global change", "2.

Forest plantations offer a considerable potential to sequester C in aboveground biomass. However, their impact on initial levels of soil organic carbon (SOC) varies from strong losses to gains, possibly affecting C balances in afforestation or reforestation initiatives. We compiled paired\uffe2\uff80\uff90plot studies on how SOC stocks under native vegetation change after planting fast\uffe2\uff80\uff90growth Eucalyptus species in Brazil, where these plantations are becoming increasingly important. SOC changes for the 0\uffe2\uff80\uff9320 and 0\uffe2\uff80\uff9340\uffe2\uff80\uff89cm depths varied between \uffe2\uff88\uff9225 and 42\uffe2\uff80\uff89Mg\uffe2\uff80\uff89ha\uffe2\uff88\uff921, following a normal distribution centered near zero.

Similar low, nonsignificant SOC changes were estimated after data were stratified into first or second rotation cycles, soil texture and biome (savanna, rainforest or grassland). Although strong SOC losses or gains effectively occurred in some cases, their underpinning causes could not be generally identified in the present work and must be ascribed in a case basis, considering the full set of environmental and management conditions. We conclude that Eucalyptus spp. plantations in average have no net effect on SOC stocks in Brazil.

One approach to quantify the contribution of management practices towards that goal is through analysis of long-term experiments (LTEs). Our objectives were to analyze knowledge gained in literature reviews on SOC changes in LTEs, to evaluate the results regarding interactions with pedo-climatological factors, and to discuss disparities among reviews in data selection criteria. We summarized mean response ratios (RRs) and stock change rate (SCR) effect size indices from twenty reviews using paired comparisons (N). The highest RRs were found with manure applications (30%, N\uffe2\uff80\uff89=\uffe2\uff80\uff89418), followed by aboveground crop residue retention and the use of cover crops (9\uffe2\uff80\uff9310%, N\uffe2\uff80\uff89=\uffe2\uff80\uff89995 and 129), while the effect of nitrogen fertilization was lowest (6%, N\uffe2\uff80\uff89=\uffe2\uff80\uff89846).

To address this need, we measured change in SOC and harvested C yield for switchgrass fields on ten farms in the central and northern Great Plains, USA (930 km latitudinal range).

Yet, the soil models embedded in Earth system models typically do not represent processes that reflect our current understanding of soil C cycling, such as microbial decomposition, mineral association, and aggregation. Rather, they rely on conceptual pools with turnover times that are fit to bulk C stocks and/or fluxes. As measurements of soil fractions become increasingly available, it is necessary for soil C models to represent these measurable quantities so that model processes can be evaluated more accurately. Here we present Version 2 (V2) of the Millennial model, a soil model developed to simulate C pools that can be measured by extraction or fractionation, including particulate organic C, mineral-associated organic C, aggregate C, microbial biomass, and low molecular weight C. Model processes have been updated to reflect the current understanding of mineral-association, temperature sensitivity and reaction kinetics, and different model structures were tested within an open-source framework. We evaluated the ability of Millennial V2 to simulate total soil organic C (SOC), as well as the mineral-associated and particulate fractions, using three independent data sets of soil fractionation measurements spanning a range of climate and geochemistry in Australia (N\u00a0=\u00a0495), Europe (N\u00a0=\u00a0175), and across the globe (N\u00a0=\u00a0659). When using all the data together (N\u00a0=\u00a01329), the Millennial V2 model predicted SOC (RMSE\u00a0=\u00a03.3\u00a0kg\u00a0C m\u22122, AIC\u00a0=\u00a0675,      R   i  n   2     \u00a0=\u00a00.31,      R   o  u  t   2     \u00a0=\u00a00.26) better than the widely-used first-order decomposition model Century (RMSE\u00a0=\u00a03.4\u00a0kg\u00a0C m\u22122, AIC\u00a0=\u00a0696,      R   i  n   2     \u00a0=\u00a00.21,      R   o  u  t   2     \u00a0=\u00a00.18) across sites, despite the fact that Millennial V2 has an increase in process complexity and number of parameters compared to Century. Millennial V2 also reproduced the observed fraction of C in MAOM and larger particle size fractions for most latitudes and biomes, and allows for a more detailed understanding of the pools and processes that affect model performance. It is important to note that this study evaluates the spatial variation in C stock only, and that the temporal dynamics of Millennial V2 remain to be tested. The Millennial V2 model updates the conceptual Century model pools and processes and represents our current understanding of the roles that microbial activity, mineral association and aggregation play in soil C sequestration.", "keywords": ["[SDU.OCEAN]Sciences of the Universe [physics]/Ocean", " Atmosphere", "2.

This SOC pool, in which a larger proportion is held in the topsoil (0\u20130.3 m), is strongly influenced by grassland management. Despite this, it is not yet fully understood how grassland SOC stocks respond to degradation, particularly for the different environmental conditions found globally. The objective of this review was to elucidate the impact of grassland degradation on changes in SOC stocks and the main environmental controls, worldwide, as a prerequisite for rehabilitation. A comprehensive meta-analysis was conducted using 55 studies with 628 soil profiles under temperate, humid, sub-humid, tropical and semi-arid conditions, to compare SOC stocks in the topsoil of non-degraded and degraded grassland soils. Grassland degradation significantly reduced SOC stocks by 16% in dry climates ( 1000 mm) and Asia was the most affected continent (\u221223.7%). Moreover, the depletion of SOC stock induced by degradation was more pronounced in sandy (<20% clay) soils with a high SOC depletion of 10% compared to 1% in clayey (\u226532% clay) soils. Furthermore, grassland degradation significantly reduced SOC by 14% in acidic soils (pH \u2264 5), while SOC changes were negligible for higher pH. Assuming that 30% of grasslands worldwide are degraded, the amount of SOC likely to be lost would be 4.05 Gt C, with a 95% confidence between 1.8 and 6.3 Gt C (i.e. from 1.2 to 4.2% of the whole grassland soil stock). These results by pointing to greater SOC losses from grasslands under dry climates and sandy acidic soils allow identification of grassland soils for which SOC stocks are the most vulnerable, while also informing on rehabilitation measures.", "keywords": ["580", "2.

However, despite the often-stated potential of agroforestry, quantitative data on the benefits of shade trees are limited to relatively few cropping systems, particularly maize and coffee. Furthermore, agroforests are not cost-free and the benefits of agroforests might not be sufficient to outweigh these costs in all cropping systems or environments. Here we quantify costs and benefits of agroforests for cocoa production in Ghana, West Africa. Specifically, we quantified the ability of shade trees to increase soil carbon stocks and soil fertility (i.e. total soil carbon, nitrogen and phosphorus, available phosphorus and potassium, cation exchange capacity, soil aggregation, pH, and foliar nitrogen and phosphorus concentrations), and investigate if these benefits are sufficient to outweigh the negative effects of shade trees on cocoa growth and yields. We measured cocoa yields, soil fertility and carbon-sequestration under individual shade trees, and in 30\u00a0\u00d7\u00a030\u00a0m plots that were distributed along a gradient of shade-tree cover (plot-scale). We found localized positive effects of individual shade trees on soil carbon and nitrogen content, as well as soil aggregation. However, we found no evidence for positive effects of agroforests via improved soil fertility or carbon-sequestration with increasing shade-tree cover at the plot scale, a scale that more closely matches the scale at which agroforests are managed. Cocoa growth was lower under individual shade trees and decreased with increasing shade-tree cover in plots, and cocoa yields also decreased with increasing shade-tree cover. Our results indicate that the benefits of agroforestry for soil fertility and carbon sequestration in cocoa cultivation systems might not be as extensive as believed, and may not be sufficient to compensate for short-term costs to production.", "keywords": ["Theobroma-Cacao", "2.

However forest harvesting may quickly affect soil carbon stocks and dynamics, especially where organic substances drive the soil-forming processes, such as in Podzols. To evaluate the effects of clear cutting on carbon dynamics and podzolisation process over a short time period, a pristine boreal forest (Komi Republic, Russian Federation) and a recently clear cut site (5\u00a0year-old) were selected. Soils are polygenic: podzolisation occurs within the clay-depleted eluvial horizon, formed by a previous lessivage process. Because podzolisation can start only after the eluvial horizon has reached a sort of threshold, bisequal soils allow to individuate comparable pedogenic conditions prior to anthropogenic disturbances.  After harvesting, C storage tended to increase in the upper part of the soil profile (organic layer and podzolic sequum) from 2.2 to 5.0\u00a0kg\u00a0m\u2212\u00a02. The abundance of woody materials on the forest floor together with an increase in soil water saturation, discernible by the vegetation survey and iron fractionation, prevented litter degradation and allowed organic matter accumulation at the soil surface. Fulvic acids (FA) in the organic layer of the pristine site showed a low incorporation of polysaccharide and proteinaceous moieties, confirming a higher degradation of the humified fraction than at the clear cut site. The lack of disturbances allowed a selection of FA with the more oxidised and mobile fractions accumulating in the deeper horizons, as currently observed in Podzols. Almost no differences were instead found in the chemical composition of FA along the profile from the clear cut site. A larger portion of FA showed the tendency to migrate through the profile after clear cutting even below the Bhs horizon (C-fulvic acid/C-humic acid >\u00a01) with a marked increase in the FA-carbon stocks with respect to the pristine forest soil (0.66 and 0.30\u00a0kg\u00a0m\u2212\u00a02 down to 30\u00a0cm, respectively).  Clear cutting also affected Al and Fe dynamics. The reducing conditions acted upon soil mineral surfaces and enhanced Fe mobilisation probably both in the ionic form and complexed with organic matter. The Al dynamics was instead more related to short term transformations of the layer silicate phases. Traces of a poorly crystalline chlorite were detectable in the Bhs in the pristine forest, but at the clear site only hydroxy-interlayered vermiculite was present. The high amounts of organic acids that migrated through the Bhs after clear cutting may have partially complexed the Al from pedogenic chlorite, giving rise to hydroxy-interlayered behaviour, as normally occurs in Podzol eluvial horizons from where the organic Al-complexes migrate.  Our findings suggested that if this trend proceeds further the whole podzolic sequum may migrate downwards. This may have important implication on C budget, as organic carbon will be transferred deeper in the soil profile limiting its losses at least over a short time period.", "keywords": ["BISEQUAL SOILS; CARBON STOCKS; CLAY MINERALOGY; FULVIC ACIDS; NORWAY SPRUCE", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

However, most present knowledge on the impact of agroforestry systems on soil organic carbon (SOC) storage comes from tropical systems. This study was conducted in southern France, in an 18-year-old agroforestry plot, where hybrid walnuts ( Juglans regia  \u00d7  nigra  L.) are intercropped with durum wheat ( Triticum turgidum  L. subsp.  durum ), and in an adjacent agricultural control plot, where durum wheat is the sole crop. We quantified SOC stocks to 2.0\u00a0m depth and their spatial variability in relation to the distance to the trees and to the tree rows. The distribution of additional SOC storage in different soil particle-size fractions was also characterized. SOC accumulation rates between the agroforestry and the agricultural plots were 248\u00a0\u00b1\u00a031\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01  for an equivalent soil mass (ESM) of 4000\u00a0Mg\u00a0ha \u2212\u00a01  (to 26\u201329\u00a0cm depth) and 350\u00a0\u00b1\u00a041\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01  for an ESM of 15,700\u00a0Mg\u00a0ha \u2212\u00a01  (to 93\u201398\u00a0cm depth). SOC stocks were higher in the tree rows where herbaceous vegetation grew and where the soil was not tilled, but no effect of the distance to the trees (0 to 10\u00a0m) on SOC stocks was observed. Most of the additional SOC storage was found in coarse organic fractions (50\u2013200 and 200\u20132000\u00a0\u03bcm), which may be rather labile fractions. All together our study demonstrated the potential of alley cropping agroforestry systems under Mediterranean conditions to store SOC, and questioned the stability of this storage.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "http://aims.fao.org/aos/agrovoc/c_28568", "Juglans regia", "F08 - Syst\u00e8mes et modes de culture", "culture associ\u00e9e", "Triticum turgidum", "630", "spectroscopie infrarouge", "zone m\u00e9diterran\u00e9enne", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_35657", "agroforesterie", "2.

Significant greenhouse gas (GHG) emissions can result from land use change due to the expansion and cultivation of soybean. However, this is complex to assess and the results can vary widely. The main goal of this article is to investigate the life-cycle GHG balance for soybean produced in Latin America, assessing the implications of direct land use change emissions and different cultivation systems. A life-cycle model, including inventories for soybean produced in three different climate regions, was developed, addressing land use change, cultivation and transport to Europe. A comprehensive evaluation of alternative land use change scenarios (conversion of tropical forest, forest plantations, perennial crop plantations, savannah and grasslands), cultivation (tillage, reduced tillage and no-tillage) and soybean transportation systems was undertaken. The main results show the importance of land use change in soybean GHG emissions, but significant differences were observed for the alternative scenarios, namely 0.1\u201317.8\u00a0kg\u00a0CO2eq\u00a0kg\u22121 soybean. The original land choice is a critical issue in ensuring the lowest soybean GHG balance and degraded grassland should preferably be used for soybean cultivation. The highest GHG emissions were calculated for tropical moist regions when rainforest is converted into soybean plantations (tillage system). When land use change is not considered, the GHG intensity varies from 0.3 to 0.6\u00a0kg CO2eq\u00a0kg\u22121 soybean. It was calculated that all tillage systems have higher GHG emissions than the corresponding no-tillage and reduced tillage systems. The results also show that N2O emissions play a major role in the GHG emissions from cultivation, although N2O emission calculations are very sensitive to the parameters and emission factors adopted.", "keywords": ["2.

However, mangroves are disappearing worldwide because of demographic increases. In addition to the loss of CO2 fixation, mangrove clearing can strongly affect soil characteristics and C storage. The objectives of the present study were to quantify the evolution of soil quality, carbon stocks and carbon fluxes after mangrove clearing. Sediment cores to assess physico-chemical properties were collected and in situ CO2 fluxes were measured at the soil-air interface in a mangrove of Northern Vietnam. We compared a Kandelia candel mangrove forest with a nearby zone that had been cleared two years before the study. Significant decrease of clay content and an increase in bulk density for the upper 35cm in the cleared zone were observed. Soil organic carbon (OC) content in the upper 35cm decreased by >65% two years after clearing. The quantity and the quality of the carbon changed, with lower carbon to nitrogen ratios, indicating a more decomposed OM, a higher content of dissolved organic carbon, and a higher content of inorganic carbon (three times higher). This highlights the efficiency of mineralization processes following clearing. Due to the rapid decrease in the soil carbon content, CO2 fluxes at sediment interface were >50% lower in the cleared zone. Taking into account carbonate precipitation after OC mineralization, the mangrove soil lost ~10MgOCha-1yr-1 mostly as CO2 to the atmosphere and possibly as dissolved forms towards adjacent ecosystems. The impacts on the carbon cycle of mangrove clearing as shown by the switch from a C sink to a C source highlight the importance of maintaining these ecosystems, particularly in a context of climate change.", "keywords": ["580", "0106 biological sciences", "2.

In Brazil, significant changes in land use result from the conversion of native vegetation to pasture and agriculture, conversion of pasture to agriculture and, more recently, the conversion of pasture and agriculture to integrated crop-livestock systems (ICL). The ICL system proposes a diversity of activities that include the strategic incorporation of pastures to agriculture so as to benefit both. In agricultural areas, for example, the implementation of ICL requires the production of quality forage for animals between crops as well as the production of straw to facilitate the sustainability of the no-tillage (NT) management system. The objective of this study was to evaluate the modifications in soil C stocks resulting from the main processes involved in the changes of land use in Amazonia and Cerrado biomes. For comparison purposes, areas under native vegetation, pastures, crop succession and ICL under different edapho-climatic conditions in Amazonia and Cerrado biomes were evaluated. This study demonstrated that the conversion of native vegetation to pasture can cause the soil to function either as a source or a sink of atmospheric CO2, depending on the land management applied. Non-degraded pasture under fertile soil showed a mean accumulation rate of 0.46\u00a0g\u00a0ha\u22121\u00a0year\u22121. Carbon losses from pastures implemented in naturally low fertile soil ranged from 0.15 to 1.53\u00a0Mg\u00a0ha\u22121\u00a0year\u22121, respectively, for non-degraded and degraded pasture. The conversion of native vegetation to agriculture in areas under the ICL system, even when cultivated under NT, resulted in C losses of 1.31 in six years and of 0.69\u00a0Mg\u00a0ha\u22121 in 21 years. The conversion of a non-degraded pasture to cropland (soybean/sorghum) released, in average, 1.44 Mg of C ha\u22121year\u22121to the atmosphere.  The ICL system in agricultural areas has shown evidences that it always functions as a sink of C with accumulation rates ranging from 0.82 to 2.58\u00a0Mg\u00a0ha\u22121\u00a0year\u22121. The ICL produces soil C accumulation and, as a consequence, reduces atmospheric CO2 in areas formerly cultivated under crop succession. However, the magnitude of C accumulation in soil depends on factors such as the types of crops, the edapho-climatic conditions and the amount of time the area is under ICL.", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "550", "limiting water range", "01 natural sciences", "630", "atlantic forest", "Amazonia", "Crop-livestock systems", "Land use change", "0105 earth and related environmental sciences", "2.

In a long-term experiment (1992-2008) we examined the effects of various tillage intensities: no-tillage (NT), minimum tillage with chisel plow (MT), and conventional tillage with mouldboard plow (CT), on the topsoil profile distribution (0-30cm) of SOC, on a semi-arid loamy soil from Central Spain. The crop sequence established was cheap pea (Cicer arietinun L.) cv. Inmaculada/barley (Hordeum vulgare L.) cv. Volley. Soil organic carbon in the various tillage treatments was expressed on a content bases and the equivalent soil mass approach. Measurements made at the end of 17 years showed that in the 0-30cm depth, stocks of SOC had increased under NT compared with MT and CT. Most dramatic changes occurred within the 0-5cm layer where plots under NT had 5.8 and 7.6Mgha-1 more SOC than under MT or CT respectively. No-tillage plots, however, exhibited strong vertical gradients of SOC with concentrations decreasing from 0-5 to 20-30cm. Stratification ratios of SOC in 1992 showed no significant differences between tillage systems. On the contrary, from 1993 onwards all stratification ratios were significantly higher in NT than in the other two tillage systems. In addition, since 2003 stratification ratios of SOC obtained under NT were systematically >2 and more than 2-fold those obtained under MT and CT.

However, due to the lack of reported studies in this field and the limited capability of the conventional measurement techniques, it is poorly understood how much VOCs could be emitted from thawing permafrost and the chemical speciation of the released VOCs. Here we apply a Vocus proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF) in laboratory incubations for the first time to examine the release of VOCs from thawing permafrost peatland soils sampled from Finnish Lapland. The warming-induced rapid VOC emissions from the thawing soils were mainly attributed to the direct release of old, trapped gases from the permafrost. The average VOC fluxes from thawing permafrost were four times as high as those from the active layer (the top layer of soil in permafrost terrain). The emissions of less volatile compounds, i.e. sesquiterpenes and diterpenes, increased substantially with rising temperatures.

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.</p>", "keywords": ["[SDV.SA]Life Sciences [q-bio]/Agricultural sciences", "0301 basic medicine", "MISCANTHUS", "330", "550", "AGRICULTURE", "01 natural sciences", "7.

We established 18 10-m radius  plots, each containing a pair of 1-m radius subplots (n =36), evenly  arrayed across three forest stands that contained areas of both high AM  and high EcM tree relative basal area as well as a patchy distribution of  the ErM shrub <em>Kalmia latifolia</em>.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0  \u00a0\u00a0 \u00a0 Within each of the 18  plots, we established paired 1-m radius subplots with and without K.  latifolia in the understory ( \u201c+/- ErM subplot\u201d) within 2 m of the center  of the 10-m radius plot. In each 1-m radius subplot, we measured trees \u22651  cm diameter at breast height (DBH; 1.37 m). We also measured DBH of all  trees \u226520 cm DBH within 10 m and trees \u22655 cm DBH within 5 m of plot  center. We calculated the percentage of EcM tree basal area out of total  basal area, scaled to m2 ha-1. \u00a0  In June 2021, we collected and pooled two soil samples for each  of three depths within the 36 paired subplots (i.e. 18 +ErM and 18 -ErM  subplots). The three depths included: (1) the Oa horizon (depth varied  depending on the thickness of the horizon); (2) the top 10 cm of the A  horizon, beginning at the base of the Oa horizon; and (3) a second,  contiguous A horizon sample that reached a cumulative sampling depth of 30  cm, inclusive of the depth of the Oa horizon. For the organic layer, we  removed the litter layer (i.e. the Oi and Oe horizons) and collected and  pooled two 25 by 25-cm areas of the Oa horizon using a square template.  For the mineral layers, we collected two contiguous depth increments from  the A horizon within the footprint of the 25 by 25-cm areas using a  5.08-cm diameter hammer corer. In each instance, we recorded the exact  sampling depth. Two subplots did not have an Oa horizon, so we collected a  total of 106 samples (3 sites \u00d7 6 plots \u00d7 2 subplots \u00d7 3 depths \u2212 2 Oa  samples). Soils were stored at 4\u00b0C prior to their analysis.  \u00a0 To prepare the soil samples for  analysis, we weighed and homogenized each sample, air dried a  representative subsample of non-sieved soil, and passed the remaining  field-moist sample through a 4-mm sieve. Using the non-sieved subsample,  we estimated the mass and volume of roots and stones and calculated soil  bulk density values. For total soil organic matter (SOM) content, we  heated samples at 550\u00b0C for 12-h in a muffle furnace and calculated loss  on ignition. \u00a0 We used a  modified substrate-induced respiration method as an indicator of active  saprotrophic microbial biomass. Using autolyzed yeast extract solution as  a labile C substrate, we measured rates of CO2 efflux over a 4-h  incubation period with an Infra-Red Gas Analyzer and calculated the rate  of C-CO2 production per unit of equivalent soil dry mass. For  microbially-available C, we estimated potential CO2 production rates over  a 14-d incubation period. We measured CO2 efflux over 24-h periods at days  1, 5, 8, and 14 and integrated the four measurements to calculate  cumulative C-CO2 production. We estimated water holding capacity by  saturating each field-moist sample with water and allowing it to drain  freely for 2 h. To calculate the equivalent dry mass of field-moist  samples, we measured gravimetric water content by oven-drying the samples  to constant mass at 105\u00b0C. \u00a0  We separated the &gt;53 and &lt;53\u2009\u00b5m particle size  fractions to quantify particulate (POM) and mineral-associated soil  organic matter fractions. We passed air-dried samples through a 2-mm sieve  and then dispersed soil aggregates by shaking ~30 g of the sieved,  air-dried sample with 30\u2009mL of sodium hexametaphosphate (NaHMP) solution  for 18 h. We rinsed each sample over a 53-\u00b5m sieve with deionized water  until the water passing through the sieve ran clear. We oven-dried the  &gt;53-\u00b5m fraction retained on the top of the sieve and a  representative subsample of the &lt;53-\u00b5m fraction suspended in  solution at 70\u00b0C. To estimate the mass of the &lt;53-\u00b5m fraction, we  calculated the difference between the initial soil mass (105\u00b0C equivalent)  and the recovered mass of the &gt;53-\u00b5m fraction (105\u00b0C equivalent).  To convert air-dried soil mass to oven-dried mass we dried a subsample of  each air-dried sample at 105\u00b0C. Fractions were ground to a fine powder and  analyzed for total carbon (C) and nitrogen (N) concentrations using a  Costech ESC 4010 Elemental Analyzer. \u00a0  We used an equivalent soil mass approach to calculate soil C,  N, SOM, microbial biomass, and microbially-available C stocks in three  equivalent soil mass layers as well as the sum of the three layers to  estimate cumulative stocks at the subplot level. Following this approach,  we report stocks to a standard soil mass and therefore allow the depth of  the equivalent soil mass layers to vary depending on soil bulk density. To  calculate equivalent soil mass stocks, we added or subtracted elemental  stocks of the deeper soil layer to the upper soil layer in 1-mm increments  until the soil mass from the upper layer is closest to that of the target  soil mass. We chose reference soil masses using the median or target field  sampling depth and the mean bulk density value for each of the three depth  increments to make them roughly equivalent to the sampled depths. Based on  this method, the organic layer had an equivalent mass of ~2.5 kg soil m-2  (median Oa depth = 2.5 cm; mean Oa bulk density = 0.10 g cm-3), the  surface mineral layer had an equivalent mass of ~37 kg soil m-2 (target  sampling depth = 10 cm; mean bulk density = 0.37 g cm-3), and the  subsurface mineral layer had an equivalent mass of ~126 kg soil m-2 (the  target sampling depth was 17.5 cm for a sample with a 2.5 cm Oa depth;  mean bulk density = 0.72 g cm-3). The cumulative equivalent soil mass for  the subplot-level stocks was the sum of the three layers, or ~166 kg soil  m-2.", "keywords": ["equivalent soil mass", "ericoid mycorrhizal fungi", "13.

Our findings derive from a total of 1108 soil cores sampled over 14 permanent plots. The observed pattern in SOC stocks reflects the very different climatic conditions and contrasting soil properties existing along the latitudinal transect. The combined effects of these factors strongly influence vegetation structure. SOC stocks in the first 2\uffc2\uffa0m of soil ranged from 20\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a Sahelian savanna in Mali to over 120\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 for a transitional forest in Ghana. The degree of interdependence between soil bulk density (SBD) and soil properties is highlighted by the strong negative relationships observed between SBD and SOC (r2\uffc2\uffa0&gt;\uffc2\uffa00.84). A simple predictive function capable of encompassing the effect of climate, soil properties and vegetation type on SOC stocks showed that available water and sand content taken together could explain 0.84 and 0.86 of the total variability in SOC stocks observed to 0.3 and 1.0\uffc2\uffa0m depth respectively. Used in combination with a suitable climatic parameter, sand content is a good predictor of SOC stored in highly weathered dry tropical ecosystems with arguably less confounding effects than provided by clay content. There was an increased contribution of resistant SOC to the total SOC pool for lower rainfall soils, this likely being the result of more frequent fire events in the grassier savannas of the more arid regions. This work provides new insights into the mechanisms determining the distribution of carbon storage in tropical soils and should contribute significantly to the development of robust predictive models of biogeochemical cycling and vegetation dynamics in tropical regions.</p>", "keywords": ["550", "Tropical ecosystems", "biotic controls", "West africa", "01 natural sciences", "forest soils", "land-use change", "Precipitation gradient", "Soil bulk density", "senegal", "cycle feedback", "Life Science", "Resistant organic carbon", "organic-matter", "0105 earth and related environmental sciences", "2.

We focused our  search on 10 priority agricultural land covers, selected according to  harvested acreage as reported by the California County Agricultural  Commissioners\u2019 2018 Crop Report [30], and 3 priority natural (i.e., not  for production purposes) land covers based on land area in the Central  Valley [98]. See Appendix II for a detailed overview of the search  strategy employed, the inclusion criteria, and the data collected from  each study in the review. The resulting library of research included  reports from peer-review studies as well as publicly available federal or  state surveys/censuses and expert source surveys. In  total, we reviewed 107 studies that included approximately 10 agricultural  land covers and 3 natural land covers, recording over 77 different metrics  for benefits and tradeoffs provisioned by those land covers.\u00a0From the 107  studies we obtained 512 unique observations across land covers and benefit  metrics.\u00a0 To  complement the metrics reported in the peer-reviewed literature, we  included metrics with quality data available in public repositories such  as federal and state censuses, technical reports, and databases. These  metrics were chosen because they provided information to supplement a  benefit category with few examples in recent published literature or  because they described metrics that are more suitable for survey formats  than for the experimental interventions in the studies reviewed above.  These additional datasets included: Crop  production value ($USD  ha<sup>-1</sup>)<sup>\u00a0</sup>   Pesticide use by land cover type (kg applied  ha<sup>-1</sup>)\u00a0 Consumptive water use  (m<sup>3</sup> ha<sup>-1</sup>)\u00a0  Employment (workers ha<sup>-1</sup>) and average  weekly wages earned ($USD worker<sup>-1</sup>  ha<sup>-1</sup>) in the agricultural sector\u00a0 Avian conservation  score The Avian Conservation Score was  developed through a survey of domain experts. In an iterative process, the  expert sources reached a consensus on scores for each landcover type  according to their relative value for nesting, foraging, or roosting  different avian taxa during the breeding and non-breeding seasons. Avian  taxa considered were those for which the Central Valley Joint Venture has  established conservation objectives, including grassland, oak savannah,  and riparian landbirds, waterfowl, shorebirds, and other waterbirds  (Central Valley Joint Venture 2020). Each land cover type was given a  final score on a 0-1 scale representing its relative total value across  taxa and seasons.\u00a0 Although our search strategy  reflected <i>a priori </i>selection of focal benefit  categories and metrics, benefit categories were subsequently adjusted to  reflect the actual availability of information on each benefit category  and associated metrics. Of the metrics described in the gap analysis  above, we chose a subset of metrics with the best representation across  land cover types and recategorized them into a suite of benefit  categories: 1) Environmental health or quality, which included air  pollution and pesticide use metrics; 2) Economy, which included  agricultural (crop and forage) production value and livelihood value  metrics; 3) Climate, which included greenhouse gas emission and carbon  storage/sequestration metrics; 4) Water, which included water  quality/pollution and water use metrics, and 5) Wildlife, which included  the Avian Conservation Score. These categories were subsequently used to  calculate a Multiple Benefits Index across land covers (within metrics)  and within specific land covers (across metrics). The Multiple Benefits Index was  calculated by normalizing all of the above metrics to a similar scale to  enable comparison of multiple benefits and tradeoffs across land cover  types. To compare benefit metrics within each landcover, reported values  were converted to the same unit of measure and then transformed to a 0-1  scale by setting the highest reported value across all land covers to 1  and then calculating the remaining values according to the following  formula: where MBI represents the Multiple Benefits Index, or normalized value of X, and X<sub>i</sub> represents a single value in the vector of values for X. Metrics were then categorized <i>post hoc </i>as either \u201cbenefits\u201d or \u201ctradeoffs\u201d depending on their perceived value to the above sectors or interests. Benefits were those metrics that related to provisioning of a desirable service such as pollutant removal, while tradeoffs were metrics that related to provisioning of an undesirable service such as greenhouse gas emissions. Metrics considered tradeoffs were assigned a negative value by multiplying the Multiple Benefits Index by -1. The results of within-land cover benefit/tradeoff analyses were presented in the individual land cover profiles in Section III, while the results of cross-land cover benefit/tradeoff analysis are presented below. To compare land covers across all metrics, we calculated the mean Multiple Benefits Index score for all metrics within a land cover type and then ranked landcovers from highest to lowest mean score. See Appendix III for the rationale behind the selected metrics, along with unit conversions and assumptions made for each metric included in the benefit-tradeoff analysis. Finally, the benefit/tradeoff analysis was placed into the context of a changing environment through the development of a Climate Change Vulnerability Index, similarly to the climate change vulnerability index developed for birds in the Central Valley.\u00a0As with the avian conservation score, we developed a survey for a panel of expert sources. The expert panel scored landcovers according to their estimated vulnerability to climate change based on a combination of sensitivity (intrinsic, physiological factors that contribute to climate change vulnerability) and exposure (extrinsic, environmental factors that contribute to climate change vulnerability) factors. Sensitivity scores and exposure scores were summed separately within each land cover and then multiplied together to derive the overall vulnerability index (sum of sensitivity*sum of exposure).\u00a0 Because it does not represent a specific benefit or tradeoff, but rather a property of individual land covers, the CCVI was not included in the benefit/tradeoff analysis. Instead, it was used as a standalone metric to contextualize benefits and tradeoffs expected from land covers under climate change and the resulting uncertainty surrounding management scenarios. Methods for spatial hotspot/coldspot analysis of ecosystem benefits/tradeoffs <b>Ecosystem Service Metrics and Source Data</b> Land cover data were obtained from the USDA NASS Cropscape Data Layer (CDL2019), and recategorized according to the specifications of this project (Table 1). Riparian zones were determined as a 25 meter buffer around National Hydrological Dataset (NHD) flowlines for natural rivers and bodies of water, limited to non-developed and non-agricultural land cover categories. Air and Water Quality metric obtained from the California Healthy Places Index (HPI) geospatial dataset, Pollution and H<sub>2</sub>O Contamination indices respectively. Habitat quality metric obtained from Department of Fish and Wildlife (CDFW) Areas of Conservation Emphasis (ACE) dataset. Soil organic carbon content and percent clay particles were aggregated from the NRCS SSURGO soil data viewer. Parameter values were aggregated from individual soil horizon by volume up to soil map unit component, and aggregated from map unit component by percent total extent to map units. Theoretical maximum carbon storage was calculated based on percent clay as per Hoyle et al (2011) by the following equation:<br> <b><i>SOC%=0.5482\u00d7 </i></b><b>ln</b><b><i>(clay%)</i></b><b><i>+1.3073</i></b> Soil potential carbon accumulation was calculated by subtracting existing soil carbon stock (SSURGO) from the theoretical maximum calculated as above, and applying a weighting factor based on land cover expected biomass productivity and soil disturbance frequency (Table 1). Rangeland and forest biomass productivity metrics were obtained from SSURGO soil data viewer by map unit component, and aggregated to map unit by percent total extent. Perennial crop biomass productivity data, previously used in orchard life cycle assessment modeling (Marvinney et al 2015, Kendall et al 2015) was obtained from a cooperating agri-services firm operating out of the San Joaquin Valley region, for 14 different tree crops. These data were joined to the CDL2019 perennial crops with average value assigned to any tree crop for which no biomass data was available. Groundwater recharge potential data was obtained from the UC Davis SAGBI dataset. Groundwater depth data was obtained from the Department of Water Resources (DWR) open test well data as the average of measurements from 2015-201 Crop productivity data (5-year mean yield in tons per acre) was obtained from the County Crop Commission (CCC) reports via USDA NASS, and joined to CDL2019 land cover units as well as recategorized land cover units as the mean yield value of any constituent crop types. The CDL 2019 original unit-based productivity analysis is thus the more accurate representation, as less aggregation of yield values was required.<br> \u00a0 <b>Transformation and Aggregation of Ecosystem Service Metrics</b> Linear transformation was used to convert the range of values in each metric dataset to a scale of 0-1, with 0 being \u2018worst\u2019 and 1 \u2018best\u2019 in terms of ecosystem services provided. Combined metrics were generated by averaging the transformed values in the relevant metrics, and applying a linear transformation to re-scale the values to 0-1. Metrics were aggregated to a 5km hex grid covering the Central Valley by area-weighted averaging. Ecosystem service \u2018hot\u2019 and \u2018cold\u2019 spots were generated by extracting hexes with values below 0.2 and above 0.8 for the combination of all examined metrics.<br> <br> \u00a0 Hoyle F.C., Baldock J.A., Murphy D.V.

Soil Improving Cropping Systems (SICS) aim to make land use and food production more sustainable. To evaluate the effect of SICS at EU scale, a modelling approach was taken. This study simulated the effects of SICS on two principal indicators of soil health (Soil Organic Carbon stocks) and land degradation (soil erosion) across Europe using the spatially explicit PESERA model. Four scenarios with varying levels and combinations of cover crops, mulching, soil compaction alleviation and minimum tillage were implemented and simulated until 2050. Results showed that while in the scenario without SICS, erosion slightly increased on average across Europe, it significantly decreased in the scenario with the highest level of SICS applied, especially in the cropping areas in the central European Loess Belt. Regarding SOC stocks, the simulations show a substantial decrease for the scenario without SICS and a slight overall decrease for the medium level scenario and the scenario with a mix of high, medium and no SICS. The scenario with a high level of SICS implementation showed an overall increase in SOC stocks across Europe. Potential future improvements include incorporating dynamic land use, climate change and an optimal spatial allocation of SICS.</p></article>", "keywords": ["2.

Large herbivores can control plant community composition and, under  certain conditions, even induce vegetation shifts to alternative ecosystem  states. As different plant assemblages maintain contrasting carbon (C)  cycling patterns, herbivores have the potential to alter C sequestration  at regional scales. Their influence is of particular interest in the  Arctic tundra, where a large share of the world\u2019s soil C reservoir is  stored. 2. We analysed how grazing mammals influence tundra vegetation and  how grazer-induced vegetation shifts affect tundra C stocks, by resampling  two sites located along pasture rotation fences in northern Norway. These  fences have separated lightly grazed areas from heavily grazed areas (in  close proximity to the fences) and moderately grazed areas (further away  from the fences) for the past 50 years. 14 years earlier, the lightly and  moderately grazed areas were dominated by dwarf shrubs, whereas heavy  grazing had promoted the establishment of graminoid-dominated vegetation.  Since then, both reindeer densities and temperatures have increased, and  more time has passed for transient dynamics to be expressed. We expected  that the vegetation and C stocks would have changed under all grazing  intensities, but not necessarily in the same way. 3. At the site where  relative reindeer numbers and trampling intensity had increased the most,  graminoid-dominated vegetation was now also found in the moderately grazed  area. At the other site, the dominant vegetation types under all grazing  intensities were the same as 14 years earlier. 4. We show that the heavily  grazed, graminoid-dominated, areas stored less C aboveground than the  lightly grazed, shrub-dominated, areas. Yet, the belowground consequences  of grazing-induced grassification varied between the sites: Grazing did  not alter organic soil C stocks at the site where both evergreen and  deciduous shrubs were abundant in the lightly grazed area, whereas heavy  grazing increased organic soil C stocks at the site where the deciduous  shrub Betula nana was dominant. 5. Our results indicate that despite the  negative impacts of grazers on aboveground C storage, their impact on  belowground C may even be positive. We suggest that the site-specific  responses of organic soil C stocks to grazing could be explained by the  differences in vegetation under light grazing. This would imply that the  replacement of deciduous shrubs by graminoids, as a consequence of  grazing, could be beneficial for C sequestration in tundra soils.", "keywords": ["carbon stocks", "Plant functional types", "13.

We predicted that  carbon stored in live aboveground biomass, aboveground necromass, and soil  components of forests on the eastern flank of the Colombian Andes would  change with elevation along this gradient extending from 750 to 2800 m  above sea level. The rationale was that the corresponding change in  temperature (14\u00b0C to 26\u00b0C) would influence tree growth and decomposition  of organic matter. To address this hypothesis, we examined the carbon  stored in these three components using data from 20 0.25-ha plots located  along this elevational gradient.

Our study, conducted in a 10\u202f000\u202fha landscape in  Xishuangbanna, SW China, aimed at assessing the spatial variability in SOC  concentrations and stocks, as well as the relationships of SOC with  land-use types, soil properties, vegetation characteristics and  topographical attributes at three spatial scales: (1) land-use types  within a landscape (10\u202f000\u202fha), (2) sampling plots (1\u202fha) nested within  land-use types (plot distances ranging between 0.5 and 12\u202fkm), and (3)  subplots (10\u202fm radius) nested within sampling plots. We sampled 27  one-hectare plots \u2013 10 plots in mature forests, 11 plots in regenerating  or highly disturbed forests, and 6 plots in open land including tea  plantations and grasslands. We used a sampling design with a hierarchical  structure. The landscape was first classified according to land-use types.  Within each land-use type, sampling plots were randomly selected, and  within each plot we sampled within nine subplots. SOC concentrations and  stocks did not differ significantly across the four land-use types.  However, within the open-land category, SOC concentrations and stocks in  grasslands were higher than in tea plantations (P\u2009&lt;\u20090.01 for  0\u20130.15\u202fm, P\u2009=\u20090.05 for 0.15\u20130.30\u202fm, P\u2009=\u20090.06 for 0\u20130.9\u202fm depth). The SOC  stocks to a depth of 0.9\u202fm were 177.6\u202f\u00b1\u202f19.6 (SE) Mg\u202fC\u202fha\u22121 in tea  plantations, 199.5\u202f\u00b1\u202f14.8\u202fMg\u202fC\u202fha\u22121 in regenerating or highly disturbed  forests, 228.6\u202f\u00b1\u202f19.7\u202fMg\u202fC\u202fha\u22121 in mature forests, and  236.2\u202f\u00b1\u202f13.7\u202fMg\u202fC\u202fha\u22121 in grasslands. In this montane landscape,  variability within plots accounted for more than 50\u202f% of the overall  variance in SOC stocks to a depth of 0.9\u202fm and the topsoil SOC  concentrations. The relationships of SOC concentrations and stocks with  land-use types, soil properties, vegetation characteristics, and  topographical attributes varied across spatial scales. Variability in SOC  within plots was determined by litter layer carbon stocks (P\u2009&lt;\u20090.01  for 0\u20130.15\u202fm and P\u2009=\u20090.03 for 0.15\u20130.30 and 0\u20130.9\u202fm depth) and slope  (P\u2009\u2264\u20090.01 for 0\u20130.15, 0.15\u20130.30, and 0\u20130.9\u202fm depth) in open land, and by  litter layer carbon stocks (P\u2009&lt;\u20090.001 for 0\u20130.15, 0.15\u20130.30 and  0\u20130.9\u202fm depth) and tree basal area (P\u2009&lt;\u20090.001 for 0\u20130.15\u202fm and  P\u2009=\u20090.01 for 0\u20130.9\u202fm depth) in forests. Variability in SOC among plots in  open land was related to the differences in SOC concentrations and stocks  between grasslands and tea plantations. In forests, the variability in SOC  among plots was associated with elevation (P\u2009&lt;\u20090.01 for 0\u20130.15\u202fm  and P\u2009=\u20090.09 for 0\u20130.9\u202fm depth). The scale-dependent relationships between  SOC and its controlling factors demonstrate that studies that aim to  investigate the land-use effects on SOC need an appropriate sampling  design reflecting the controlling factors of SOC so that land-use effects  will not be masked by the variability between and within sampling plots.", "keywords": ["Soil organic carbon stocks", "Land-use type", "Soil characteristics", "15.

Partial cutting, which removes some individual trees from a forest, is one of the major and widespread forest management practices that can significantly alter both forest structure and carbon (C) storage. Using 746 observations from 82 publications, we synthesized the impacts of partial cutting on three variables associated with forest structure (i.e. mean annual growth of diameter at breast height (DBH), basal area (BA), and volume) and four variables related to various C stock components (i.e. aboveground biomass C (AGBC), understory C, forest floor C, and mineral soil C). Results shows that the growth of DBH elevated by 112% after partial cutting, compared to the uncut control, while stand BA and volume reduced immediately by 34% and 29%, respectively. On average, partial cutting reduced AGBC by 43%, increased understory C storage by 392%, but did not show significant effects on C storages on forest floor and in mineral soil. All the effects on DBH growth, stand BA, volume, and AGBC intensified linearly with cutting intensity (CI) and decreased linearly with the number of recovery years (RY). In addition to the strong impacts of CI and RY, other factors such as climate zone and forest type also affected forest responses to partial cutting. The data assembled in this synthesis were not sufficient to determine how long it would take for a complete recovery after cutting because long-term experiments were rare. Future efforts should be tailored to increase the duration of the experiments and balance geographic locations of field studies.                         </p>", "keywords": ["Biomass (ecology)", "0106 biological sciences", "Sustainable forest management", "Volume (thermodynamics)", "Diameter at breast height", "Forest Carbon Sequestration", "Estimation of Forest Biomass and Carbon Stocks", "Quantum mechanics", "01 natural sciences", "Environmental science", "Basal area", "Agricultural and Biological Sciences", "Life", "Forest structure", "QH501-531", "Development and Impacts of Bioenergy Crops", "FOS: Mathematics", "Climate change", "Carbon stock", "Agroforestry", "Biology", "QH540-549.5", "Nature and Landscape Conservation", "QE1-996.5", "Global and Planetary Change", "Understory", "Forest management", "Ecology", "Geography", "Physics", "Confidence interval", "Statistics", "Canopy", "Life Sciences", "Geology", "Forestry", "15.
