Agroforestry (AF) has the potential to restore degraded lands, provide a broader range of ecosystem goods and services such as carbon (C) sequestration and high biodiversity, and increase soil fertility and ecosystem stability through additional C input from trees, erosion prevention, and microclimate improvement. Advantages and processes for global C sequestration in AF are unknown. We used a meta\uffe2\uff80\uff90analysis of 427 soil C stock data pairs grouped into four main AF systems\uffe2\uff80\uff94alley cropping, windbreaks, silvopastures, and homegardens\uffe2\uff80\uff94and evaluated changes in AF and adjacent control cropland or pasture. Mean soil C stocks in AF (1\uffe2\uff80\uff90m depth) were 126\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffb7ha\uffe2\uff88\uff921, which is 19% more than that in cropland or pasture. The highest C stocks in soil were in subtropical homegardens, AF with younger trees, and topsoil (0\uffe2\uff80\uff9320\uffc2\uffa0cm). Increased soil C stocks in AF were lower than aboveground C stocks in most AF systems, except alley cropping. Homegardens stored the highest C in both aboveground and belowground, especially in the subsoil (20\uffe2\uff80\uff93100\uffc2\uffa0cm). Advantages of AF ecosystem services focusing on mechanisms of belowground C sequestration were analyzed. AF could store 5.3\uffc2\uffa0\uffc3\uff97\uffc2\uffa0109\uffc2\uffa0Mg additional C in soil on 944\uffc2\uffa0Mha globally, with most in the tropics and subtropics. AF systems could greatly contribute to global soil C sequestration if used in larger areas. Future investigations of AF should include (a) mechanistic\uffe2\uff80\uff90 and process\uffe2\uff80\uff90based studies (instead of common monitoring and inventories), (b) models linking forest and crop growth with soil water and C and nutrient cycling, and (c) accurate assessments of the AF area worldwide based on the remote sensing approaches.

The Quesungual slash-and-mulch agroforestry system (QSMAS) of western Honduras offers a promising alternative to traditional slash-and-burn (SB) agriculture for the mountainous tropical dry forest zones of Central America, but the overall influence of this system on soils is not fully understood. We examined earthworm populations, soil fertility and soil organic matter (SOM) dynamics under QSMAS and SB agriculture, with secondary forest (SF) as a reference. Both QSMAS and SB consisted of treatments with and without inorganic fertilizer (N\u2013P\u2013K) additions, resulting in five management treatments, each present on three replicate farms. Baseline soil samples (0\u201315\u00a0cm) were collected prior to forest clearing and establishment of QSMAS plots in 2003 and in SB and SF plots in 2005 to determine initial soil concentrations of C and N. Soils were sampled in 2006 and 2007 for bulk soil C and N and P availability, as well as for aggregate fractionation and determination of C and N within the different aggregate size fractions. Earthworm populations were assessed in July 2007. Earthworm numbers and biomass were higher under QSMAS than under SB (13.4 vs. 0.8\u00a0g fresh biomass m \u2212\u00a02 ; respectively). Significant interactions between cropping system and fertilization suggest that QSMAS increased the availability of added inorganic P, 3 times more under QSMAS than for SB. Comparisons with SF, indicated that both cropping systems resulted in a dramatic loss of C (average 5\u00a0g\u00a0C\u00a0kg \u2212\u00a01 soil) since treatment implementation, and that this loss was mainly associated with the disruption of C rich large macroaggregates (>\u00a02000\u00a0\u00b5m). After taking into account baseline soil C differences between plots, no major differences in total SOM losses were found between QSMAS and SB management. However, earlier establishment of QSMAS plots suggests that the overall rate of C loss since treatment establishment was lower for QSMAS than for SB. Results from this study suggest that the Quesungual agroforestry system offers great potential to improve soil fertility and biological health in the region relative to traditional slash-and-burn agriculture.", "keywords": ["2.

To evaluate its potential, we used climatically suitable ranges for parklands for 19 climate scenarios, derived by ecological niche modeling, for estimating potential carbon stocks in parkland and treeless cropland. A biocarbon business model was used to evaluate profitability of hypothetical Terrestrial Carbon Projects (TCPs), across a range of farm sizes, farm numbers, carbon prices and benefit sharing mechanisms. Using climate analogues, we explored potential climate change trajectories for selected locations. If mature parklands covered their maximum range, carbon stocks in Sahelian productive land would be about 1,284\uffc2\uffa0Tg, compared to 725\uffc2\uffa0Tg in a treeless scenario. Due to slow increase rates of total system carbon by 0.4\uffc2\uffa0Mg\uffc2\uffa0C\uffc2\uffa0ha\uffe2\uff88\uff921 a\uffe2\uff88\uff921, most TCPs at carbon prices that seem realistic today were not feasible, or required the participation of large numbers of farmers. For small farms, few TCP scenarios were feasible, and low Net Present Values for farmers made it unlikely that carbon payments would motivate many to participate in TCPs, unless additional benefits were provided. Climate analogue locations indicated an uncertain climate trajectory for the Sahel, but most scenarios projected increasing aridity and reduced suitability for parklands. The potentially severe impacts of climate change on Sahelian ecosystems and the uncertain profitability of TCPs make the Sahel highly risky for carbon investments. Given the likelihood of degrading environmental conditions, the search for appropriate adaptation strategies should take precedence over promoting mitigation activities.

A few studies have shown that Piliostigma reticulatum , a dominant native shrub in parklands from Senegal to Sudan, can positively impact crop yields. However, there are no experiments that measure whether this species can stabilize long-term crop productivity under erratic rainfall. Therefore, an 11-year study of an optimized P. reticulatum intercropping system (1000 shrubs ha \u22121 with annual coppiced residue soil amendments) was initiated in 2004 in Senegal, West Africa to determine its impacts on crop productivity and soil quality. The experiment was a split-plot factorial design with the main plot shrubs (with and without) and the subplot fertilizer rate (0, 0.5, 1, and 1.5 times the recommended N-P-K rate) with an annual groundnut ( Arachis hypogaea ) and pearl millet ( Pennisetum glaucum ) crop rotation. Yield, biomass, soil carbon, and soil and plant nutrient data from 2011 to 2015 were compared with data from 2004 to 2007. The presence of shrubs increased millet and groundnut yield from 2011 to 2015 and rainfall water use efficiency (WUE) between 2004 and 2015. Without fertilizer addition, the shrub plots had approximately 2 times greater millet yield throughout the duration of this experiment. The presence of shrubs also improved soil quality, as evidenced by significantly greater C in the fraction P. reticulatum intercropping promotes C sequestration. In addition, five macronutrients (N, K, Ca, Mg, S) and two micronutrients (Mn and Cu) were significantly greater in the shrub plots. The results provide strong evidence that intercropping with P. reticulatum is an ecological agroforestry system for the Sahel that can remediate soils, increase crop yields, and buffer climate change.", "keywords": ["580", "Pearl millet", "2.

The consequent downward spiral of soil fertility has led to a corresponding decline in crop yields, food insecurity, food aid and environmental degradation. The central issue for improving agricultural productivity in southern Africa is how to build up and maintain soil fertility despite the low incomes of smallholder farmers and the increasing land and labour constraints they face. Under this review five main options namely: inorganic fertilizers, grain legumes, animal manures, integrated nutrient management and agroforestry options appropriate to smallholder farmers are presented. Issues addressed in the use of inorganic fertilizers are reduction in fertilizer costs, timely availability and use efficiency. Legumes can be used to diversify farm system productivity but this requires P and lime application to support better legume growth and biological nitrogen fixation (BNF) as well as development of markets for various legume products. Manure availability and quality are central issues in increasing smallholder farm productivity and increasing its efficiency through proper handling and application methods. Integrated nutrient management of soil fertility by combined application of both inputs will increase use efficiency of inputs and reduce costs and increase profitability; but the challenge is often how to raise adequate amounts of either inorganic or organic inputs. Issues such as quality of inputs, nutrient balancing, labour to collect and transport organic inputs and their management need to be optimized. These are the challenges of adoption as are the scaling up of these options to millions of small-scale farmers.", "keywords": ["0106 biological sciences", "grain legumes", "fertilidad del suelo", "leguminosas de grano", "01 natural sciences", "agroforestry", "12.

Residual P And Leaf Management Effects On Maize Nutrition And Soil Properties", "description": "Agroforestry systems involving leaf removal for animal fodder may result in rapid depletion of soil fertility. The purpose of this research was to determine if the effects of leaf removal on soil fertility parameters and maize yield in a Leucaena leucocephala alley cropping system could be reversed. Three leaf management strategies in a Leucaena alley cropping trial that had been in effect from 1987 to 1991 were investigated: 1) leaves returned, 2) leaves removed, and 3) leaves removed, with 100 kg inorganic N ha\u22121 added. In the 1990/91 season, a 34 confounded factorial design was utilized to investigate the effects of leaf management strategy, N rate (0, 30 and 60 kg N ha\u22121); maize plant population (14,800, 29,600, and 44,400 plants ha\u22121); and P rate (0, 18, and 35 kg P ha\u22121). In the 1991/92 and 1992/93 seasons, leaves were applied equally to all plots, and no P was applied. The N rate and plant population treatments were continued, and the same confounded factorial design was implemented to investigate residual leaf management strategy, residual P rate, n rate, and plant population. The yield gap between the plots where leaves had been returned vs. removed narrowed each season due to uniform leaf application. Application of N improved yields during both seasons. Residual effects of the initial P application decreased to only 10% of the total yield in 1992/93. Plant population affected yields only during the season of very good rainfall. Leaf additions resulted in a relative increase in soil pH, total N,and exchangeable Ca, Mg, and K and a decrease C/N ratio in plots that had not previously received leaves. Leaves supplied more K and Zn to the upper 15 cm of soil than were being extracted by the maize crop, but uniform leaf additions eliminated differences in K and Zn uptake. Plant Zn uptake decreased with increasing P rate and plant population, and increased with increasing N rate and a history of leaf return. The results show that applying leaves equilibrated yields within two seasons, and resulted in a relative improvement of several soil properties. The residual effect from P applications was not adequate to maximize yields.", "keywords": ["alley cropping", "2.

Soil cores were collected and analyses in mid-autumn 2009, in intercropped agroforestry (AF), pure tree (FC) and sole crop control (CC) plots. The SMN was significantly reduced in AF compared to CC (64, 58 and 51 % of reduction at 0.2, 1 and 2 m depth respectively). In the top 1 m of soil, the stock of SMN was 77.7 kg N ha\u22121 in CC versus 32.8 kg N ha\u22121 in AF. Trees in AF developed deeper fine roots than in FC, likely involved in the reduction of SMN when compared to CC. Despite this quantitative reduction, trees also progressively modified the form of mineral N in soil by decreasing the percentage of nitrate (NO3 \u2212) in SMN, particularly in FC compared to CC, while AF was intermediate. The STN was not significantly different between AF and CC; but was higher in FC in the top soil, probably due to weeds and superficial tree root biomasses.

Soil organic carbon (SOC) was analyzed in the whole soil to 1\u00a0m depth and to 0.4\u00a0m in macroaggregates (2000\u2013250\u00a0\u03bcm), microaggregates (250\u201353\u00a0\u03bcm), and silt and clay-sized aggregates (<53\u00a0\u03bcm) to provide information of C dynamics and stabilization in various land uses. Synchrotron-based C K-edge x-ray absorption near-edge structure (XANES) spectroscopy was also used to study the influence of these land use systems on the soil organic matter (SOM) chemistry to understand the mechanisms of soil C changes.

SOC in the woodlots were found to be associated more with the micro and silt-and clay-sized aggregates than with macroaggregates, reflecting higher stability of SOC in the woodlot systems. The continuous addition of litter in the woodlots preserved recalcitrant aromatic C compounds in the silt and clay-sized aggregates as revealed by the XANES C K-edge spectra.

Site preparation for tree establishment is a common practice that can involve a variety of techniques and agricultural implements such as subsoiling. This study aimed to evaluate the long-term effects of subsoiling on soil organic carbon (SOC) concentrations and stocks in a Mediterranean grassland afforested with holm oaks 22\uffc2\uffa0years ago and now converted into a Dehesa agroforestry system. The study was conducted in a dehesa farm in Southwest Spain. Soil samples were taken at six depths under 10 tree canopies within and outside the original subsoiling line. Subsoiling significantly decreased SOC concentration. Mean SOC concentration in the first 20\uffc2\uffa0cm was 30% lower at the subsoiling line. SOC stocks for the first 60\uffc2\uffa0cm were 2660\uffc2\uffa0g\uffc2\uffa0m\uffe2\uff88\uff922 within the subsoiling line and 4320\uffc2\uffa0g\uffc2\uffa0m\uffe2\uff88\uff922 outside the line. There was a clear reduction in SOC concentration and stock with increasing depth. Root abundance and deeper rooting increased with subsoiling but did not translate into sufficient carbon accumulation in the soil, which is moderate even after 22\uffc2\uffa0years. This study reveals that, in the long term, there is a trade-off in CO2 sequestration between tree planting and soil subsoiling, highlighting the need for further research into the potential benefits and detriments of subsoiling.1 300 millions).

Les options de gestion pr\u00e9sentant le plus grand potentiel d'att\u00e9nuation pour le riz ou les syst\u00e8mes de culture \u00e0 base de riz sont le travail de conservation, l'irrigation contr\u00f4l\u00e9e\u00a0; le remplacement de l'ur\u00e9e par du sulfate d'ammonium, l'application d'inhibiteurs d'azote (N), l'application d'engrais \u00e0 teneur r\u00e9duite en azote, la culture int\u00e9gr\u00e9e du riz, du poisson et du canard et l'application de biochar. Une r\u00e9duction de 15\u00a0% de l'application moyenne actuelle d'engrais azot\u00e9s synth\u00e9tiques pour le riz en Chine, soit 231 kg N ha\u22121, entra\u00eenerait une diminution de 12\u00a0% des \u00e9missions directes d'oxyde nitreux (N2O) dans le sol. L'application combin\u00e9e d'engrais chimiques et organiques, le travail de conservation, l'application de biochar et l'application r\u00e9duite d'azote sont des mesures possibles qui peuvent r\u00e9duire les \u00e9missions globales de GES des syst\u00e8mes de culture en montagne. Les apports d'engrais conventionnels pour les l\u00e9gumes de serre repr\u00e9sentent plus de 2 \u00e0 8 fois la demande optimale en nutriments des cultures. Une r\u00e9duction de 20 \u00e0 40\u00a0% de l'application d'engrais azot\u00e9s sur les cultures mara\u00eech\u00e8res peut r\u00e9duire les \u00e9missions de N2O de 32 \u00e0 121\u00a0%, sans avoir d'impact n\u00e9gatif sur le rendement. L'une des mesures d'att\u00e9nuation les plus importantes pour les prairies agricoles pourrait \u00eatre la conversion de terres cultiv\u00e9es \u00e0 faible rendement, en particulier sur les pentes, en terres arbustives ou en prairies, ce qui est \u00e9galement une option prometteuse pour r\u00e9duire l'\u00e9rosion des sols. En outre, l'exclusion du p\u00e2turage et la r\u00e9duction de l'intensit\u00e9 du p\u00e2turage peuvent augmenter la s\u00e9questration du COS et r\u00e9duire les \u00e9missions globales tout en am\u00e9liorant les prairies largement d\u00e9grad\u00e9es.

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.

We found 1) no significant effect of shade trees on coffee production overall; 2) evidence that shade trees do affect flowering and subsequent cherry development, with effects strongly dependent on climate and annual variations in coffee plant physiology; 3) Erythrina shade trees significantly increased soil litter and relative infiltration rate of water in the soil, both linked to soil conservation and decrease in erosion; 4) even in highly fertilized environments, Erythrina trees do fix N which was taken up by adjacent coffee plants. The lack of significant negative effect of shade trees on overall coffee yield and the observation of the provision of other useful services was not unexpected, because of 1) the low density of shade trees in the study site (100\u2013350 trees/ha pruned twice a year on average) and 2) the sensitivity of coffee yields to other interacting effects such as climate, pests and diseases and physiological variations in the plant.

Appropriate species compositions and spacing regimes are critical to achieve ecosystem benefits and improve yields of all the component crops. Cocoa (Theobroma cacao) is an important cash crop globally but it requires shade for survival and growth. However, the effects of shade-tree species composition and spacing regime on nutrient cycling in cocoa plantations are not well understood. This study investigated the effects of shade tree species and spacing regimes on soil and plant nutrient availability at 8 years after plantation establishment in Papua New Guinea. Three cocoa intercropping systems were established in which T. cacao was planted with either a non-legume timber tree, Canarium indicum, or a legume non-timber tree, Gliricidia sepium. The shade-tree spacing regimes included either 8 m \u00d7 16 m or 8 m \u00d7 8 m in the Theobroma + Canarium plantations. There was an ongoing thinning regime in the Theobroma + Gliricidia plantation, with a final shade-tree spacing of 12 m \u00d7 12 m. Soil total carbon (TC) and total nitrogen (TN) were significantly higher in the Theobroma + Gliricidia plantation with 12 m \u00d7 12 m spacing and the Theobroma + Canarium plantation with 8 m \u00d7 16 m spacing than in the Theobroma + Canarium plantation with 8 m \u00d7 8 m spacing. Foliar TN and P were correlated with soil TN and P, respectively, whereas no correlation was detected between soil and leaf K concentrations. Foliar TN, P and K were under ideal concentrations for T. cacao in all of the plantations. The Theobroma + Gliricidia plantation had higher soil water extractable phosphorus (P) than the two Theobroma + Canarium plantations, probably due to frequent pruning of the G. sepium trees. Foliar C isotope composition (\u03b413C) of T. cacao suggested that T. cacao close to G. sepium or close to C. indicum with spacing of 8 m \u00d7 16 m and 8 m \u00d7 8 m had similar light interception. However, increased C. indicum spacing increased the light interception of T. cacao trees that were not planted next to C. indicum. This study indicated that non-legume timber trees with an optimized spacing regime can be used as overstorey shade trees for T. cacao. However, our study indicated all three plantations required fertilisation and better nutrient management.", "keywords": ["571", "stable isotopes", "FoR 16 (Studies in Human Society)", "Canarium indicum", "Soil fertility", "Gliricidia sepium", "333", "630", "Papua New Guinea", "veterinary and food sciences", "Stable isotopes", "2.

Allometric equations were built for upscaling tree biomass at the plot scale. Biomass of understory vegetation and crops were estimated at the plot scale in the three land uses. Tree diameter was 19 % higher in the AF than in TP, likely due to different light microclimate, while tree height did not vary significantly between land uses. Tree biomass allocation to aboveground and belowground compartments (70 % and 30 % of total tree biomass, respectively) did not vary between land uses. Higher efficiency in building tree carbon stock was shown in agroforestry than in tree plantation per area unit. Trees accounted for 39 % and 66 % of total carbon stocks in biomass in AF and TP, respectively. Understory vegetation accounted for 8 % and 34 % of total carbon stocks in biomass in AF and TP, respectively.

To address this issue, we evaluated the influence of common agricultural management practices (cropping and livestock systems) vs. the Quesungual slash-and-mulch agroforestry system (QSMAS) on diverse parameters of soil quality and function. We then used this information to identify soil invertebrate bioindicators that represent key aspects of soil quality (chemical fertility, physical properties, aggregate morphology, and biological functioning). In February of 2011 soil sampling was conducted on six hillside farms near the town of Somotillo in western Nicaragua to assess soil properties and the abundance and diversity of soil macrofauna within four management systems: (1) QSMAS, based on maize production, (2) traditional maize cropping system with few trees (TC), (3) silvopastoral system with low tree density (SP), and (4) secondary forest (SF), used as a reference.

Soil organic matter mineralization and the following microbial parameters: microbial biomass C, mineralization quotient, metabolic quotient and activities of four enzymes: \u03b2-glucosidase, cellobiohydrolase, phosphatase and chitinase were determined. Microbial biomass C content, \u03b2-glucosidase, cellobiohydrolase and chitinase activities were higher in natural systems compared to agricultural soils. High phosphatase activity observed in all land use types reflected strong phosphorus limitation in andic soils of the Mt. Kilimanjaro region. Chitinase activity in montane forest soils was 3 times higher than in Chagga homegardens. Mineralization quotient and cellobiohydrolase activity best exhibited the effect of land-use changes on soil quality in the Mt. Kilimanjaro region. Cellobiohydrolase activity was up to 3 times higher under natural ecosystems compared to agroecosystems. A high percentage of microbial biomass C content in total organic C and low metabolic quotient were observed in Chagga homegarden soils. Soil enzymes (especially cellobiohydrolase) best distinguished between natural and agricultural ecosystems, and are therefore useful for monitoring changes in soil quality. In conclusion, the measured microbial parameters clearly show that the microbial organisms in traditional Chagga homegardens system have high substrate use efficiency.

We worked with a community in Eastern Panama to determine the average above- and below-ground C stocks of three land-use types in their territory: managed forest, agroforests and pasture. We examined evidence for a functional relationship between tree-species diversity and C storage in each land-use type, and also explored how the use of particular tree species by community members could affect C storage. We found that managed forests in this landscape stored an average of 335 Mg C ha \ufffd 1 , traditional agroforests an average of 145 Mg C ha \ufffd 1 , and pastures an average of 46 Mg C ha \ufffd 1 including all vegetation-based C stocks and soil C to 40 cm depth. We did not detect a relationship between diversity and C storage; however, the relative contributions of species to C storage per hectare in forests and agroforests were highly skewed and often were not proportional to species\u2019 relative abundances. We conclude that protecting forests from conversion to pasture would have the greatest positive impact on C stocks, even though the forests are managed by community members for timber and non-timber forest products. However, because several of the tree species that contribute the most to C storage in forests were identified by community members as preferred timber species, we suggest that species-level management will be important to avoiding C-impoverishment through selective logging in these forests. Our data also indicate that expanding agroforests into areas currently under pasture could sequester significant amounts of carbon while providing biodiversity and livelihood benefits that the most common reforestation systems in the region \u2013 monoculture teak plantations \u2013 do not provide. # 2007 Elsevier B.V.

Soil C and N stocks were highest in moist forest (18.3 kg C m\u22122 and 0.66 kg of N m\u22122) and lowest in the miombo (8.5 kg m\u22122 of C and 0.22 kg of N m\u22122). Average soil C among Pinus stands was 11.4 kg of C m\u22122, being highest at 10 years (13.7 of C kg m\u22122) and lowest at 1 year (9.9 kg of C m\u22122). Some inputs of charcoal through bioturbation over the 25 year period contributed to stabilisation of soil organic carbon (SOC) and its depth distribution compared to the one year old stands. Nitrogen was highest at 10 years (0.85 kg of N m\u22122) and least at 30 years (0.22 kg of N m\u22122). Carbon and N in density fractions showed the 20 year old stand having similar proportions of fLF and oLF while the rest had significantly higher fLF than oLF. The contribution of fLF C, oLF C and MaHF C to SOC was 8\u201313%, 1\u20137% and 90\u201391% respectively. Carbon and N in all fractions decreased with depth. The mineral associated C was significantly affected by stand age whilst the fLF and oLF were not. Conversion of depleted miombo woodlands to pine plantations yield better C gains in the short and long run whilst moist forest provide both carbon and biodiversity. Our results highlight the importance of considering forestry age based C pools in estimating C sink potential over a rotation and the possibility of considering conservation of existing natural forests as part of future REDD + projects.", "keywords": ["0106 biological sciences", "Technology", "Economics", "vertical-distribution", "organic-carbon", "Soil Science", "natural resources management", "01 natural sciences", "630", "agroforestry", "forest floor", "storage", "land-use", "climate", "agriculture", "tropical forests", "2.

La legislaci\u00f3n brasile\u00f1a exige que todas las fincas del pa\u00eds mantengan y protejan las \u00e1reas forestales conocidas como Reservas Legales. Dado que las Reservas Legales tienen importantes implicaciones para la protecci\u00f3n de los bosques y la producci\u00f3n agr\u00edcola, es clave que entendamos las percepciones de los propietarios de tierras hacia las Reservas Legales. Aplicamos la metodolog\u00eda Q para identificar diferentes perspectivas de los propietarios medianos y grandes sobre las Reservas Legales y su relaci\u00f3n con la intensificaci\u00f3n agr\u00edcola en el municipio de Paragominas, en la Amazon\u00eda oriental. Realizamos 31 entrevistas en las que los propietarios ordenaron 36 declaraciones en una matriz de distribuci\u00f3n casi normal. Se identificaron tres grupos de propietarios de tierras: 1) los entusiastas de la planificaci\u00f3n del uso de la tierra (n = 16) estaban interesados en iniciativas de zonificaci\u00f3n para explorar dise\u00f1os de paisajes alternativos y legislaci\u00f3n que puedan ofrecer mejores resultados de conservaci\u00f3n y producci\u00f3n; 2) los partidarios de la agricultura basada en agroqu\u00edmicos (n = 7) ten\u00edan los puntos de vista m\u00e1s cr\u00edticos contra las Reservas Legales y percib\u00edan sus costos como m\u00e1s altos que los posibles beneficios ambientales y de calidad de vida; 3) los respondedores del mercado complacientes con las pol\u00edticas (n = 4) no mostraron inter\u00e9s en las reformas de las Reservas Legales y fueron el grupo m\u00e1s impulsado por el mercado. Si bien Paragominas ha logrado \u00e9xitos notables en detener la deforestaci\u00f3n a gran escala a trav\u00e9s de un pacto social de 'Municipio Verde', abordar la persistente degradaci\u00f3n y fragmentaci\u00f3n de los bosques en la regi\u00f3n sigue siendo una prioridad clave. Las iniciativas de gobernanza local que tienen en cuenta las percepciones de m\u00faltiples partes interesadas sobre la protecci\u00f3n de los bosques pueden fomentar el di\u00e1logo y el entendimiento mutuo para conservar y restaurar eficazmente las Reservas Legales. Los conocimientos sobre las percepciones de los grandes terratenientes sobre las Reservas Legales pueden informar dichos procesos de gobernanza para conciliar la protecci\u00f3n forestal y la intensificaci\u00f3n agr\u00edcola sostenible en Paragominas.", "keywords": ["Amazonas (Brasil)", "Economics", "FOS: Political science", "SAO-FELIX", "Social Sciences", "NEEDS", "01 natural sciences", "Agricultural and Biological Sciences", "Reservas Forestales", "Natural resource economics", "conservation des for\u00eats", "FRONTIER", "Stakeholder", "11.

Our objective was to characterise the soil inorganic (Pi) and organic P (Po) pools and to compare the various pools at different depths in agroforestry (shaded) and monocultural (unshaded) coffee cultivation systems. The study was carried out in the Atlantic Coastal Rainforest domain, Brazil, with Oxisols as the dominant soil type. Soils were collected from four farmers' coffee (Coffea arabica L.) fields, two agroforestry and two monocultural systems. Three profiles were sampled per field, at depths of 2\u20133, 10\u201315 and 40\u201360 cm. A simplified sequential P fractionation was carried out, using resin, 0.5 M NaHCO3, 0.1 M NaOH, 1 M HCl and concentrated HCl as extractants. Sum-P (resin, NaHCO3 NaOH, 1 M HCl and concentrated HCl) ranged from 370 to 830 mg kg\u22121. Concentrated HCl extracted the largest portion (74%), followed by NaOH (22.5%). Labile (sum of resin, NaHCO3 and NaOH) P ranged from 13 to 40% of Sum-P. The major part (62%) of the labile fraction was Po. In the agroforestry fields, the amount of Po decreased less with depth and the percentage of Po in labile pools was higher than in monocultural fields.

Land use changes and land use intensification are considered important processes contributing to the increasing concentrations of the greenhouse gases nitrous oxide (N2O) and methane (CH4) and of nitric oxide (NO), a precursor of ozone. Studies on the effects of land use changes and land use intensification on soil trace gas emissions were mostly conducted in Latin America and only very few in Asia. Here we present results from Central Sulawesi where profound changes in land use and cultivation practices take place: traditional agricultural practices like shifting cultivation and slash\uffe2\uff80\uff90and\uffe2\uff80\uff90burn agriculture are replaced by permanent cultivation systems and introduction of income\uffe2\uff80\uff90generating cash crops like cacao. Our results showed that N2O emissions were higher from cacao agroforestry (35 \uffc2\uffb1 10 \uffce\uffbcg N m\uffe2\uff88\uff922 h\uffe2\uff88\uff921) than maize (9 \uffc2\uffb1 2 \uffce\uffbcg N m\uffe2\uff88\uff922 h\uffe2\uff88\uff921), whereas intermediate rates were observed from secondary forests (25 \uffc2\uffb1 11 \uffce\uffbcg N m\uffe2\uff88\uff922 h\uffe2\uff88\uff921). NO emissions did not differ among land use systems, ranging from 12 \uffc2\uffb1 2 \uffce\uffbcg N m\uffe2\uff88\uff922 h\uffe2\uff88\uff921 for cacao agroforestry and secondary forest to 18 \uffc2\uffb1 2 \uffce\uffbcg N m\uffe2\uff88\uff922 h\uffe2\uff88\uff921 for maize.

Combining these data with results from other studies in this area, we present chronosequence effects of land use change on trace gas emissions from natural forest, through maize cultivation, to cacao agroforestry (with or without fertilizer). Compared to the original forests, this typical land use change in the study area clearly led to higher N2O emissions and lower CH4 uptake with age of cacao agroforestry systems. We conclude that this common land use sequence in the area combined with the increasing use of fertilizer will strongly increase soil trace gas emissions. We suggest that the future hot spot regions of high N2O (and to a lesser extend NO) emissions in the tropics are those areas where climatic and edaphic conditions allow for intensive agriculture. This scenario is probably preferable over the alternative of agriculture extensification, which would imply a dramatic increase in deforestation rates with accompanying CO2 emissions.

Restoration of abandoned farmlands could counter this process. However, as aims and modes of restoration differ in their ecological and socio-economic value, the assessment of achievable ecosystem functions and benefits requires holistic investigation. Here we combine the results from multidisciplinary research for a unique assessment based on a normalization of 23 ecological, economic and social indicators for four restoration options in the tropical Andes of Ecuador. A comparison of the outcomes among afforestation with native alder or exotic pine, pasture restoration with either low-input or intense management and the abandoned status quo shows that both variants of afforestation and intense pasture use improve the ecological value, but low-input pasture does not. Economic indicators favour either afforestation or intense pasturing. Both Mestizo and indigenous Saraguro settlers are more inclined to opt for afforestation.

Yet their capacity to support multiple ecosystem services simultaneously (multiservices) compared with nearby natural ecosystems remains virtually unknown. We conducted a global field survey in 56 urban areas to investigate the influence of urban greenspaces on 23 soil and plant attributes and compared them with nearby natural environments. We show that, in general, urban greenspaces and nearby natural areas support similar levels of soil multiservices, with only six of 23 attributes (available phosphorus, water holding capacity, water respiration, plant cover, arbuscular mycorrhizal fungi (AMF), and arachnid richness) significantly greater in greenspaces, and one (available ammonium) greater in natural areas. Further analyses showed that, although natural areas and urban greenspaces delivered a similar number of services at low (>25% threshold) and moderate (>50%) levels of functioning, natural systems supported significantly more functions at high (>75%) levels of functioning. Management practices (mowing) played an important role in explaining urban ecosystem services, but there were no effects of fertilisation or irrigation. Some services declined with increasing site size, for both greenspaces and natural areas. Our work highlights the fact that urban greenspaces are more similar to natural environments than previously reported and underscores the importance of managing urban greenspaces not only for their social and recreational values, but for supporting multiple ecosystem services on which soils and human well-being depends.This study evaluates the dynamics of soil organic carbon (SOC) under perennial crops across the globe. It quantifies the effect of change from annual to perennial crops and the subsequent temporal changes in SOC stocks during the perennial crop cycle. It also presents an empirical model to estimate changes in the SOC content under crops as a function of time, land use, and site characteristics. We used a harmonized global dataset containing paired\uffe2\uff80\uff90comparison empirical values of SOC and different types of perennial crops (perennial grasses, palms, and woody plants) with different end uses: bioenergy, food, other bio\uffe2\uff80\uff90products, and short rotation coppice. Salient outcomes include: a 20\uffe2\uff80\uff90year period encompassing a change from annual to perennial crops led to an average 20% increase in SOC at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (6.0\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.6\uffc2\uffa0Mg/ha gain) and a total 10% increase over the 0\uffe2\uff80\uff93100\uffc2\uffa0cm soil profile (5.7\uffc2\uffa0\uffc2\uffb1\uffc2\uffa010.9\uffc2\uffa0Mg/ha). A change from natural pasture to perennial crop decreased SOC stocks by 1% over 0\uffe2\uff80\uff9330\uffc2\uffa0cm (\uffe2\uff88\uff922.5\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.2\uffc2\uffa0Mg/ha) and 10% over 0\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9213.6\uffc2\uffa0\uffc2\uffb1\uffc2\uffa08.9\uffc2\uffa0Mg/ha). The effect of a land use change from forest to perennial crops did not show significant impacts, probably due to the limited number of plots; but the data indicated that while a 2% increase in SOC was observed at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (16.81\uffc2\uffa0\uffc2\uffb1\uffc2\uffa055.1\uffc2\uffa0Mg/ha), a decrease in 24% was observed at 30\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9240.1\uffc2\uffa0\uffc2\uffb1\uffc2\uffa016.8\uffc2\uffa0Mg/ha). Perennial crops generally accumulate SOC through time, especially woody crops; and temperature was the main driver explaining differences in SOC dynamics, followed by crop age, soil bulk density, clay content, and depth. We present empirical evidence showing that the FAO perennialization strategy is reasonable, underscoring the role of perennial crops as a useful component of climate change mitigation strategies.
