Cocoa based agroforestry systems are credited for stocking significant amounts of carbon and hence have the potential to mitigate climate change. Since cocoa yields decrease non-linearly with increasing shade, a need is to design optimal cocoa agroforestry systems with high yields and high carbon stocks. We estimated the carbon stocked in a network of 229 permanent sample plots in cacao-based agroforestry systems and natural forests in five Central American countries. Carbon stocks were fractioned by both system compartments (aboveground, roots, soil, litter, dead wood \u2013 fine and coarse, and total) and tree use/form (cocoa, timber, fruit, bananas, shade and ornamentals, and palms). Cocoa plantations were assigned to a five-class typology and tested for independence with growing region using contingency analysis. Most Central American cocoa plantations had mixed or productive shade canopies. Only 4% of cocoa plantations were full sun or rustic (cocoa under thinned natural forest). Cocoa tree density was low (548\u00a0\u00b1\u00a0192\u00a0trees\u00a0ha\u22121). Total carbon (soil\u00a0+\u00a0biomass\u00a0+\u00a0dead biomass) was 117\u00a0\u00b1\u00a047\u00a0Mg\u00a0ha\u22121, with 51\u00a0Mg\u00a0ha\u22121 in the soil and 49\u00a0Mg\u00a0ha\u22121 (42% of total carbon) in aboveground biomass (cocoa and canopy trees). Cocoa trees accumulated 9\u00a0Mg\u00a0C\u00a0ha\u22121 (18% of carbon in aboveground biomass). Timber and fruit trees stored 65% of aboveground carbon. The annual rate of accumulation of carbon in aboveground biomass ranged between 1.3 and 2.6\u00a0Mg\u00a0C\u00a0ha\u22121\u00a0y\u22121. Trade-offs between carbon levels and yields were explored qualitatively using functional relationships documented in the scientific and technical literature, and expert knowledge. We argue that it is possible to design cocoa-based AFS with good yields (cocoa and shade canopy) and high carbon stock levels. The botanical composition of the shade canopy provides a large set of morphological and functional traits that can be used to optimize shade canopy design. Our results offer Central American cocoa producers a rigorous estimate of carbon stocks in their cocoa plantations. This knowledge may help them to certify and sell their cocoa, timber, fruits and other goods to niche markets with good prices. Our results will also assist governments and the private sector in (i) designing better legal, institutional and policy frameworks, local and national, promoting an agriculture with trees and (ii) contributing to the development of the national monitoring, reporting and verification systems required by the international community to access funding and payment for ecosystem services.", "keywords": ["0106 biological sciences", "certification", "F08 - Syst\u00e8mes et modes de culture", "rendement des cultures", "http://aims.fao.org/aos/agrovoc/c_1920", "stockage", "01 natural sciences", "http://aims.fao.org/aos/agrovoc/c_10176", "http://aims.fao.org/aos/agrovoc/c_5524", "http://aims.fao.org/aos/agrovoc/c_7427", "K01 - Foresterie - Consid\u00e9rations g\u00e9n\u00e9rales", "biomasse", "Theobroma cacao", "service", "http://aims.fao.org/aos/agrovoc/c_1666", "http://aims.fao.org/aos/agrovoc/c_1301", "plante d'ombrage", "agroforesterie", "2.

In the Itasy region, AFS were introduced to improve farmers' livelihoods by diversifying income sources and to address problems related to soil degradation. Previous studies in the region have shown the potential of AFS to store organic carbon in the soil. In the present work, we carried out further studies to assess the main factors affecting SOC stocks in AFS. In 2014, we performed a soil sampling on 137 AFS farmers'plots to assess SOC stocks in different AFS. In 2018, a second sampling was carried out to calculate SOC storage rates using the diachronic approach on 30 most representative AFS. The results revealed that the factors 'age of the system' and 'type of organic inputs' significantly affected SOC stocks in AFS. SOC stocks increased significantly over time in AFS plots, benefiting from regular organic inputs such as manure and/or compost. In contrast, SOC stocks remained unchanged over time in AFS plots where no organic fertilization was used. Our study showed a substantial SOC storage up to 47 parts per thousand year(-1), mainly explained by regular additions of organic inputs to maintain soil fertility and crop production. However, to fully understand the process of SOC storage in this context, further works, such as the analysis of the link between organic matter quality and the SOC storage process, and the quantification of the share of soil carbon inputs derived from tree biomass should be undertaken.", "keywords": ["[SDV.SA.SF]Life Sciences [q-bio]/Agricultural sciences/Silviculture", "agro\u00e9cologie", "stockage", "petite exploitation agricole", "http://aims.fao.org/aos/agrovoc/c_330982", "[SDV.SA.SDS]Life Sciences [q-bio]/Agricultural sciences/Soil study", "910", "630", "Tropical", "syst\u00e8mes agroforestiers", "http://aims.fao.org/aos/agrovoc/c_7427", "C sequestration", "TreeTropical", "http://aims.fao.org/aos/agrovoc/c_1721", "http://aims.fao.org/aos/agrovoc/c_1301", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_4510", "http://aims.fao.org/aos/agrovoc/c_35657", "agroforesterie", "2.

Agroforestry practices may also promote mineral N fertilization and the use of N2-fixing legumes that favor the emission of non-CO2 greenhouse gases (GHG) (N2O and CH4). The present study evaluates the net GHG balance in two adjacent coffee plantations, both highly fertilized (250 kg N ha-1 year-1): a monoculture (CM) and a culture shaded by the N2-fixing legume tree species Inga densiflora (CIn). C stocks, soil N2O emissions and CH4 uptakes were measured during the first cycle of both plantations. During a 3-year period (6-9 years after the establishment of the systems), soil C in the upper 10 cm remained constant in the CIn plantation (+0.09 \u00b1 0.58 Mg C ha-1 year-1) and decreased slightly but not significantly in the CM plantation (-0.43 \u00b1 0.53 Mg C ha-1 year-1). Aboveground carbon stocks in the coffee monoculture and the agroforestry system amounted to 9.8 \u00b1 0.4 and 25.2 \u00b1 0.6 Mg C ha-1, respectively, at 7 years after establishment. C storage rate in the phytomass was more than twice as large in the CIn compared to the CM system (4.6 \u00b1 0.1 and 2.0 \u00b1 0.1 Mg C ha-1 year-1, respectively). Annual soil N2O emissions were 1.3 times larger in the CIn than in the CM plantation (5.8 \u00b1 0.5 and 4.3 \u00b1 0.3 kg N-N2O ha-1 year-1, respectively). The net GHG balance at the soil scale calculated from the changes in soil C stocks and N2O emissions, expressed in CO2 equivalent, was negative in both coffee plantations indicating that the soil was a net source of GHG. Nevertheless this balance was in favor of the agroforestry system. The net GHG balance at the plantation scale, which includes additionally C storage in the phytomass, was positive and about 4 times larger in the CIn (14.59 \u00b1 2.20 Mg CO2 eq ha-1 year-1) than in the CM plantation (3.83 \u00b1 1.98 Mg CO2 eq ha-1 year-1). Thus converting the coffee monoculture to the coffee agroforestry plantation shaded by the N2-fixing tree species I. densiflora would increase net atmospheric GHG removals by 10.76 \u00b1 2.96 Mg CO2 eq ha-1 year-1 during the first cycle of 8-9 years.", "keywords": ["P33 - Chimie et physique du sol", "570", "571", "[SDV]Life Sciences [q-bio]", "F08 - Syst\u00e8mes et modes de culture", "http://aims.fao.org/aos/agrovoc/c_1920", "stockage", "Funders: EU CASCA project", "http://aims.fao.org/aos/agrovoc/c_24345", "01 natural sciences", "630", "agroforestry", "leguminous tree", "soil organic matter", "http://aims.fao.org/aos/agrovoc/c_7427", "andosol", "gaz \u00e0 effet de serre", "http://aims.fao.org/aos/agrovoc/c_1721", "http://aims.fao.org/aos/agrovoc/c_34841", "http://aims.fao.org/aos/agrovoc/c_1666", "http://aims.fao.org/aos/agrovoc/c_1301", "Inga", "syst\u00e8me de culture", "http://aims.fao.org/aos/agrovoc/c_35657", "0105 earth and related environmental sciences", "agroforesterie", "2.

Our objectives were to quantify the changes in aggregate size distribution, aggregate-C concentrations and stocks upon conversion of native vegetation (NV) to conventional plow-based tillage (CT), and to assess the rate of aggregation and SOC recovery with no-till (NT) under diverse biomass-C inputs. The study was conducted at both sub-tropical (Ponta Grossa \u2013 PG, State of Parana) and tropical (Lucas do Rio Verde \u2013 LRV, State of Mato Grosso) sites in Brazil. The SOC content under NV was used as a baseline to evaluate the depletion rate under CT and the restoration rate under NT. A specific emphasis was given to the largest macroaggregate size class (8\u201319\u00a0mm) because of its importance to protecting the recently deposited labile SOC. A discriminant analysis of principal components (DAPC) indicated that NV soil is modified by conversion to an arable land use and that, mechanical tillage, biomass input, and their interactions drastically influence the distribution of aggregate-size classes, aggregation indices, and SOC distribution within aggregates. At both sites, soil aggregation indices were positively impacted by NT and associated with SOC concentration in the labile fractions (e.g., total polysaccharides (TPS), hot water extractable organic C (HWEOC), particulate organic C (POC)). At the PG site, the 8\u201319\u00a0mm aggregate size fraction was significantly affected by land use and tillage treatments and represented 54%, 43%, and 72%, under NV, CT, and NT in 0\u201320\u00a0cm depth, respectively. Furthermore, the 8\u201319\u00a0mm size fraction stored 55%, 45%, and 71% of the total SOC stock under NV (53.8\u00a0Mg\u00a0C\u00a0ha \u22121 ), CT (28.5\u00a0Mg\u00a0C\u00a0ha \u22121 ) and NT (51.2\u00a0Mg\u00a0C\u00a0ha \u22121 ), respectively. At the LRV site, the 8\u201319\u00a0mm aggregate size fraction decreased from 50% under Cerrado NV to 35% under CT, and ranged from 33% to 51% under diverse biomass-C input under NT in 0\u201320\u00a0cm depth. The 8\u201319\u00a0mm size fraction stored 52%, 37%, and 41% of the total SOC stock across all aggregate sizes under NV (25.4\u00a0Mg\u00a0C\u00a0ha \u22121 ), CT (11.7\u00a0Mg\u00a0C\u00a0ha \u22121 ), and NT (9.9\u201318.1\u00a0Mg\u00a0C\u00a0ha \u22121 ), respectively.

Case studies are needed to assess the effect of such land use changes on soil fertility and C sequestration. In this study, the influence of Cerrado land development (pasture andEucalyptusplantations) on soil organic carbon (SOC) and nitrogen (SON) stocks were quantified in southern Brazil. Two contrasted silvicultural practices were also compared: 60\uffe2\uff80\uff83years of short\uffe2\uff80\uff90rotation silviculture (EUCSR) versus 60\uffe2\uff80\uff83years of continuous growth (EUCHF). C and N soil concentrations and bulk densities were measured and modelled for each vegetation type, and SOC and SON stocks were calculated down to a depth of 1\uffe2\uff80\uff83m by a continuous function.</p><p>Changes in SOC and SON stocks mainly occurred in the forest floor (no litter in pasture and up to 0.87\uffe2\uff80\uff83kg C\uffe2\uff80\uff83m\uffe2\uff88\uff922and 0.01\uffe2\uff80\uff83kg N\uffe2\uff80\uff83m\uffe2\uff88\uff922in EUCSR) and upper soil horizons. C and N stocks and their confidence intervals were greatly influenced by the methodology used to compute these layers. C/N ratio and13C analysis showed that down to a depth of 30\uffe2\uff80\uff83cm, the Cerrado organic matter was replaced by organic matter from newly introduced vegetation by as much as 75\uffe2\uff80\uff93100% for pasture and about 50% for EUCHF, poorer in N forEucalyptusstands (C/N larger than 18 forEucalyptusstands). Under pasture, 0\uffe2\uff80\uff9330\uffe2\uff80\uff83cm SON stocks (0.25\uffe2\uff80\uff83kg N\uffe2\uff80\uff83m\uffe2\uff88\uff922) were between 10 and 20% greater than those of the Cerrado (0.21\uffe2\uff80\uff83kg N\uffe2\uff80\uff83m\uffe2\uff88\uff922), partly due to soil compaction (limit bulk density at soil surface from 1.23 for the Cerrado to 1.34 for pasture). Land development on the Cerrado increased SOC stocks in the 0\uffe2\uff80\uff9330\uffe2\uff80\uff83cm layer by between 15 and 25% (from 2.99 (Cerrado) to 3.86 (EUCSR)\uffe2\uff80\uff83kg C\uffe2\uff80\uff83m\uffe2\uff88\uff922). When including litter layers, total 0\uffe2\uff80\uff9330\uffe2\uff80\uff83cm carbon stocks increased by 35% for EUCHF(4.50\uffe2\uff80\uff83kg C\uffe2\uff80\uff83m\uffe2\uff88\uff922) and 53% for EUCSR(5.08\uffe2\uff80\uff83kg C\uffe2\uff80\uff83m\uffe2\uff88\uff922), compared with the Cerrado (3.28\uffe2\uff80\uff83kg C\uffe2\uff80\uff83m\uffe2\uff88\uff922), independently of soil compaction.</p>", "keywords": ["P33 - Chimie et physique du sol", "sol", "http://aims.fao.org/aos/agrovoc/c_24420", "http://aims.fao.org/aos/agrovoc/c_7071", "http://aims.fao.org/aos/agrovoc/c_5192", "STOCKS ET FLUX", "stockage", "[SDV.SA.SDS]Life Sciences [q-bio]/Agricultural sciences/Soil study", "910", "ORGANIC-MATTER DYNAMICS", "utilisation des terres", "p\u00e2turages", "http://aims.fao.org/aos/agrovoc/c_7427", "MANAGEMENT", "http://aims.fao.org/aos/agrovoc/c_5626", "savane", "http://aims.fao.org/aos/agrovoc/c_1301", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_35657", "azote", "2.
