51. The contribution of agroforestry systems to improving soil carbon sequestration

Author

Koutika, Lydie-Stella, Marron, Nicolas, and Cardinael, Rémi

Abstract

Agroforestry is a land-use system where woody perennials are deliberately combined with agricultural crops and/or livestock on the same land-management units in some form of spatial arrangement or temporal sequence. Agroforestry has the potential to respond to multiple challenges related to soil carbon sequestration including soil fertility improvement, land restoration, food security and adaptation and resilience to climate change. In this chapter, we show how agroforestry systems (AFSs) address several of the above-mentioned challenges, and play a key role in boosting soil carbon sequestration (SCS) and improving soil functions. Other co-benefits are also considered, i.e., soil and ecosystem services, and the wellbeing of rural populations (increase in income, access to non-timber products, etc.), mainly in the less developed countries. Attention is also paid to the main barriers, which may lessen or halt SCS in AFSs. We make recommendations for implementing and improving AFSs to foster SCS and to meet the challenges faced by human societies in the 21st century.

Abstract

Food insecurity in sub-Saharan Africa (SSA) is partly due to low staple crop yields, resulting from low soil fertility and low nutrient inputs. Integrated soil fertility management (ISFM), that includes the combined use of mineral and organic fertilizers, can contribute to increasing yields and sustaining soil organic carbon (SOC) in the long term. Soil-crop simulation models help assess the performance of ISFM under current and future climate. Yet, uncertainty in model predictions can be high, resulting from poor model calibration and/or inadequate model structure. Multi-model assessments help understand model uncertainty and reduce it. We compared the performance of 16 soil-crop models using data from four long-term experiments at sites in SSA with contrasting climates and soils. Each experiment had four experimental treatments: i) no exogenous inputs, ii) addition of mineral nitrogen (N), iii) organic amendments, and iv) combined mineral and organic inputs. We assessed model performance after partial and full calibration. Model ensemble accuracy was greater with full calibration than with partial calibration, and improved more for crop yields (rRMSE 53 vs 17%) than for SOC (RMSE 21 vs 12%). Uncertainty of model simulations increased over the course of the long-term experiments. Uncertainty with SOC simulations increased when organic amendments were added to the soil, whilst uncertainty with yield predictions was largest when no inputs were applied. Differences between individual models were linked to uncertainties in simulating roots and soil N dynamics. The discrepancies between models increased when organic amendments were applied. Our study is the first multi-model comparison for long-term simulations of crop yield and SOC and their feedbacks in SSA. The results highlight the need for long-term experiments that monitor roots and N dynamics and provide the corresponding data required for soil-crop model improvements and calibration.

Abstract

This study quantified soil organic carbon (SOC) and soil total nitrogen (STN) changes in three long-term (14 years) experiments comparing conventional tillage (CT) and different no-till (NT) cropping systems using a diachronic approach and an equivalent soil mass approach. The three experiments were established in 2009 in a randomized complete block design with three replicates and comprise maize (MaiEx)-, soybean (SoyEx)-, and cassava (CasEx)-based cropping systems. Soil samples were collected in 2021, 10 years after the first sampling (2011), at 7 depths: 0–5, 5–10, 10–20, 20–40, 40–60, 60–80, and 80–100 cm. At 0–10 cm depth, NTs significantly increased SOC stock at a rate of 0.35, 0.51 and 0.73 Mg C ha-1 y-1 for CasEx, SoyEx and MaiEx, respectively. CT exhibited a positive trend only on CasEx with an accumulation rate of 0.14 Mg C ha-1 y-1 (0-10 cm). A significant SOC accumulation was observed under NT cropping systems for CasEX and MaiEx up to 60-80 and 80-100 cm depth, respectively. By contrast, STN stock significantly increased under NT cropping systems only at 0–5 cm depth with an accumulation rate of 13.9, 22.9 and 34.0 kg N ha-1 y-1 under CasEx, SoyEx and MaiEx, respectively. A depletion of N stocks was observed under CT and NT cropping systems at deeper soil layers. Over 10 years of time, SOC accumulation rate of NT, at 0-100 cm depth, reached 1.08 and 1.73 Mg C ha-1 yr-1 for CasEx and MaiEx, respectively while non-significant change was observed under NT SoyEx and CT of the three experiments. The findings suggest that long-term NT cropping systems with high amount of biomass-C inputs and crop rotation enhance SOC sequestration even at deeper soil layers. However, these results raise questions about the dynamics of N under NT cropping systems.

Abstract

Conservation agriculture (CA), combining reduced or no tillage, permanent soil cover and improved rotations, is often promoted as a climate-smart practice. However, our understanding about the impact of CA and its respective three principles on top and sub-soil organic carbon (SOC) stocks and on soil CO2 efflux in low input cropping systems of sub-Saharan Africa is rather limited. The study was conducted at two long-term experimental sites established in 2013 in Zimbabwe. The soil types were abruptic Lixisols at Domboshava Training Centre (DTC) and xanthic Ferralsol at the University of Zimbabwe farm (UZF). Six treatments, replicated four times were investigated: conventional tillage (CT), conventional tillage with rotation (CTR), NT, no-tillage with mulch (NTM), no-tillage with rotation (NTR), no-tillage with mulch and rotation (NTMR). Maize (Zea mays L.) was the main crop and treatments with rotation included cowpea (Vigna unguiculata L. Walp.). SOC concentration and bulk density were determined for samples taken from the 0–5, 5–10, 10–15, 15–20, 20–30, 30–40, 40–50, 50–75 and 75–100 cm depths. Gas samples were regularly collected using the static chamber method during the 2019/20 and 2020/21 cropping seasons and during the 2020/21 dry season. SOC stocks were significantly (p < 0.05) higher under NTM, NTR and NTMR compared to NT and CT in top 5 and 10 cm layers at UZF, while SOC stocks were only significantly higher under NTM and NTMR compared to NT and CT in top 5 cm at DTC. NT alone had a slightly negative impact on top SOC stock. Cumulative SOC stocks were not significantly different between treatments when considering the whole 100 cm soil profile. Regardless of larger organic carbon inputs in mulch treatments, there were no significant differences in CO2 efflux between treatments, but it was higher in maize rows than in inter-rows as a result of autotrophic respiration from maize roots. Our results show the overarching role of crop residue mulching in CA cropping systems in enhancing SOC storage but that this effect is limited to the topsoil. [ABSTRACT FROM AUTHOR]

Abstract

We have read with interest an opinion paper recently published in the European Journal of Soil Science (Berthelin et al., 2022). This paper presents some interesting considerations, at least one of which is already well known to soil scientists working on soil organic carbon (SOC), that is, a large portion (80%–90%) of fresh carbon inputs to soil is subject to rapid mineralization. The short-term mineralization kinetics of organic inputs is well-known and accounted for in soil organic matter models. Thus, clearly, the long-term predictions based on these models do not overlook short-term mineralization. We point out that many agronomic practices can significantly contribute to SOC sequestration. If conducted responsibly whilst fully recognising the caveats, SOC sequestration can lead to a win-win situation where agriculture can both contribute to the mitigation of climate change and adapt to it, whilst at the same time delivering other co-benefits such as reduced soil erosion and enhanced biodiversity.

Abstract

Major drivers of gains or losses in soil organic carbon (SOC) include land management, land-use change, and climate change. Thousands of original studies have focused on these drivers of SOC change and are now compiled in a growing number of meta-analyses. To critically assess the research efforts in this domain, we retrieved and characterized 192 meta-analyses of SOC stocks or concentrations. These meta-analyses comprise more than 13,200 original studies conducted from 1910 to 2020 in 150 countries. First, we show that, despite a growing number of studies over time, the geographical coverage of studies is limited. For example, the effect of land management, land-use change, and climate change on SOC has been only occasionally studied in North and Central Africa, and in the Middle East and Central Asia. Second, the meta-analyses investigated a limited number of land management practices, mostly mineral fertilization, organic amendments, and tillage. Third, the meta-analyses demonstrated relatively low quality and transparency. Lastly, we discuss the mismatch between the increasing number of studies and the need for more local, reusable, and diversified knowledge on how to preserve high SOC stocks or restore depleted SOC stocks.

70. Agroforestry as a climate solution: Moving from potential to practice

Abstract

Global estimates indicate that agroforestry provides the largest opportunity for agricultural carbon sequestration, while simultaneously delivering diverse benefits to farmers and society, placing it among the most promising natural climate solutions (NCS). Policy and financial actions to support a transition to agroforestry are predicated on the ability to consistently identify agroforestry systems, estimate their carbon benefits, and monitor them over time. However, our review finds critical gaps in each of these areas: climate-positive agroforestry is poorly defined, mitigation estimates are imprecise and use only a fraction of available carbon data, and detection and monitoring are hindered by uncertainty in field and remote-sensing data. To pave the path from theory to practice, we refine standard agroforestry definitions to the subset of agroforestry NCS practices, highlight underappreciated opportunities for agroforestry expansion, and identify avenues to leverage existing data and emerging techniques to predict, map, measure, and track agroforestry's contribution to climate progress.

Abstract

There is growing interest in agroforestry as a climate solution, given its potential to store additional carbon in agricultural landscapes, while also enhancing livelihoods and biodiversity. However, substantial uncertainty remains around how much carbon can be captured, and how that varies by location and by practice. One of the central challenges is the sheer diversity of agroforestry practices employed across the globe. Species identity, planting density, and management practices, as well as many other factors, will influence the overall climate mitigation potential of an individual agroforestry system. Although recent reviews have begun to compile carbon sequestration rates and stocks within agroforestry systems, the current evidence base is not fully comprehensive. Individual reviews have examined only a subset of the existing literature and typically partition agroforestry systems into coarse categories that do not reflect the diversity of actual on-the-ground practices. As individuals, corporations, and governments decide whether and how to deploy agroforestry as a climate solution during this climate critical decade, there is a strong need for a readily available and comprehensive dataset to better predict climate outcomes across diverse agroforestry systems. We have therefore conducted a systematic review of published studies to find empirical estimates of carbon sequestration rates and stocks in agroforestry systems. After reviewing over 18,000 papers, we have identified 800 or more papers that appear to have the necessary information. We are compiling this information into a consistent data structure to create a publicly available dataset that can help to accelerate our scientific understanding of the climate mitigation potential of agroforestry and facilitate the incorporation of agroforestry into climate goals. Although agroforestry offers high potential as a climate solution, delivering on that promise requires a more precise understanding of how much carbon can actually be captured, based on the best available data.

Abstract

Following the Paris agreement (COP21), France set a carbon neutrality objective by 2050. Given its contribution to national GHG emissions (20%), the French agricultural sector is expected to play its part in achieving this ambitious target. It can act on three levers: N2O and CH4 emissions reduction, renewable energy production, and carbon storage in biomass and soil, the latter being less studied. The recent controversy on the 4 per 1000 initiative has also emphasized the need for a quantitative assessment of the potential for and cost of additional C storage in agricultural soils at the national level. Eight carbon storing practices were identified based on a literature review: expansion of cover crops; mobilization of new C inputs (not already spread on agricultural soils under current management practices); expansion of temporary grasslands (instead of silage maize); agroforestry; hedges; moderate intensification of extensive grasslands (+50kgN/ha); animal grazing instead of mowing and grass cover of vineyard. We assessed and mapped their potential for additional carbon storage in soils at a very fine spatial scale (1 km2), using a crop model (STICS) and a grassland model (PASIM). The additional C storage was calculated as the difference between the simulated soil C stock under i) the C storing practices and ii) the current management practices (i.e. the baseline), after a 30 years period. Using public statistics, we then assessed for each C storing practice: its potential applicability, its implementation cost, and its efficiency at the regional level. Using an economic model (BANCO), we finally compute the cost-effective allocation of the additional carbon storage effort, i.e. the uptake level of each storing practice in each region that minimizes the total cost of achieving a given total additional C storage target in mainland France. By varying this national storage target, we are able to depict a marginal carbon storage cost curve. Our results show a potential for additional C storage of about 8.43 Mt C/year for a total cost of 2.3 bn€/yr, which would compensate 6.8% of national GHG emissions and 41% of the agricultural sector emissions. This potential is mainly found in arable soils, where initial soil C stocks are low. Moreover, 96% of this potential can be achieved at a lower cost than 250€/tCO2e (the 2030 target carbon price in France) and for a total cost of 1.6 bn€/yr, which corresponds to only 18% of the current French budget for the Common Agricultural Policy. Reaching high soil C storage targets implies the full implementation of cover crops and agroforestry, together with the expansion of temporary grasslands in crop rotations. The costs and potential for additional C storage vary both between practices and across regions. This is why there is no “one-size-fits- all” solution, rather a combination of good practices at the right place. Our results thus provide useful information for the design of efficient climate change mitigation policies. Besides highlighting the potential for additional C storage in arable soils, where initial stocks are low, our study also underlines the need to maintain soil C stocks where they are high, i.e. in grasslands and forest soils.

Abstract

L'initiative "4 pour mille : les sols pour la sécurité alimentaire et le climat" propose d'augmenter chaque année d'un quatre millième le stock de carbone présent dans tous les sols du monde. À la demande de l'Ademe et du ministère de l'Agriculture et de l'Alimentation, l'Inra (devenu aujourd'hui INRAE) a conduit une étude, centrée sur la France métropolitaine, visant à estimer le potentiel de stockage de carbone des sols agricoles et forestiers et, in fine, à mesurer la contribution potentielle de ce levier à l'objectif de réduction des émissions nettes de gaz à effet de serre. Diverses pratiques candidates (cultures intermédiaires, apport de nouvelles ressources organiques, gestion des prairies, agroforesterie…) ont été évaluées. Les résultats obtenus ont montré une forte variabilité du stockage additionnel de carbone. L'étude a également permis d'estimer le coût supplémentaire, pour les agriculteurs, de mise en oeuvre de ces pratiques de stockage, puis une allocation de l'effort de stockage entre les pratiques et les régions a été effectuée. Ces données permettront aux différents acteurs concernés de faire les meilleurs choix pour stocker davantage de carbone dans les sols. Cet ouvrage s'adresse aux décideurs chargés de l'élaboration des politiques publiques climatiques dans le domaine agricole, aux responsables territoriaux, aux aménageurs, aux ingénieurs et techniciens, aux agriculteurs et à l'ensemble des citoyens intéressés par la problématique de l'agriculture et du changement climatique.

Abstract

International audience; L’initiative « 4 pour 1 000 : les sols pour la sécurité alimentaire et le climat » propose d’augmenter chaque année d’un quatre millième le stock de carbone présent dans tous les sols du monde. À la demande de l’Ademe et du ministère de l’Agriculture et de l’Alimentation, l’Inra (devenu aujourd’hui INRAE) a conduit une étude, centrée sur la France métropolitaine, visant à estimer le potentiel de stockage de carbone des sols agricoles et forestiers et, in fine, à mesurer la contribution potentielle de ce levier à l’objectif de réduction des émissions nettes de gaz à effet de serre. Diverses pratiques candidates (cultures intermédiaires, apport de nouvelles ressources organiques, gestion des prairies, agroforesterie…) ont été évaluées. Les résultats obtenus ont montré une forte variabilité du stockage additionnel de carbone. L’étude a également permis d’estimer le coût supplémentaire, pour les agriculteurs, de mise en œuvre de ces pratiques de stockage, puis une allocation de l’effort de stockage entre les pratiques et les régions a été effectuée. Ces données permettront aux différents acteurs concernés de faire les meilleurs choix pour stocker davantage de carbone dans les sols. Cet ouvrage s’adresse aux décideurs chargés de l’élaboration des politiques publiques climatiques dans le domaine agricole, aux responsables territoriaux, aux aménageurs, aux ingénieurs et techniciens, aux agriculteurs et à l’ensemble des citoyens intéressés par la problématique de l’agriculture et du changement climatique.

Abstract

There is increasing demand for data on soil organic carbon (SOC) stock (SSOC; kgC m−2), but the acquisition of such data, which relies on the determination of volumetric SOC content (SOCv; gC dm−3), is often tedious or complex. Visible and near infrared reflectance spectroscopy (VNIRS) has proven useful for soil characterization, but has rarely been used for direct prediction of SOCv. The objectives of this work were: (i) to compare SOCv predictions using VNIR spectra collected in situ vs. on 2-mm sieved air-dried soil (laboratory conditions), on three sample sets separately (with in situ spectra collected differently for each set); and (ii) to assess SOCv prediction in independent validation using laboratory spectra from all sets. Predictions of SOCv were more accurate using laboratory than in situ spectra for two sets, but not for the third set, where coarse particles content was rather high and variable. Considering the total set of laboratory spectra, predictions in independent validation (leave-one-site-out) yielded accurate SOCv and SSOC predictions (standard errors of prediction were 1.9 gC dm−3 and 0.36 kgC m−2 at 0–30 cm depth, respectively). This result was achieved using local partial least squares regression (PLSR), based on spectral neighbors, which noticeably outperformed global PLSR (which uses all calibration samples equally), as often reported when using large soil spectral libraries for independent validation. Finally, this work demonstrated that SSOC could be quantified accurately using a VNIRS library built on archive soil samples, which offers important perspectives for SSOC accounting.

Abstract

L’initiative « 4 ‰ sur les sols pour la sécurité alimentaire et le climat », lancée par la France à l’occasion de la Conférence de Paris sur le climat (COP-21), propose d’augmenter chaque année d’un quatre millième le stock de carbone présent dans tous les sols du monde afin de compenser les émissions anthropiques de CO2. Cet objectif, très ambitieux, nécessite des évolutions profondes des pratiques agricoles et des modes de gestion sylvicoles, certaines pouvant s’accompagner de modifications de systèmes de production et, éventuellement, des modes d’usage des sols. C'est dans ce contexte que le Ministère de l’Agriculture et de l’Alimentation (MAA) et l’Agence De l'Environnement et de la Maîtrise de l'Energie (ADEME) ont demandé à l'INRA de conduire la présente étude "4 pour mille France". Les objectifs étaient : i) d’identifier des pratiques agricoles et sylvicoles plus "stockantes" que les pratiques actuellement mises en œuvre ; ii) de chiffrer le potentiel de stockage additionnel associé, de le cartographier, de quantifier les autres effets induits liés à l’adoption de ces pratiques stockantes (pertes ou gains de rendement, émissions de N2O, lixiviation de nitrate, utilisation de produits phytosanitaires...) ; iii) de chiffrer leur coût de mise en œuvre et de proposer une stratégie coût-efficace de stockage. Le présent document constitue le rapport scientifique de cette étude.Ce travail a fait l'objet de documents de synthèse et d'un colloque public de restitution, qui s'est tenu à Paris le 13 juin 2019.

Abstract

Identifying the drivers of soil organic carbon (SOC) stock changes is of utmost importance to contribute to global challenges like climate change, land degradation, biodiversity loss or food security. Evaluating the impacts of land-use and management practices in agriculture and forestry on SOC is still challenging. Merging datasets or making databases interoperable is a promising way but still with several semantic challenges. So far, a comprehensive thesaurus and classification of management practices in agriculture and forestry is lacking, especially while focussing on SOC storage. Therefore, the aim of this paper is to present a first comprehensive thesaurus for management practices driving SOC storage (DATA4C+). The DATA4C+ thesaurus contains 226 classified and defined terms related to land management practices in agriculture and forestry. It is organized as a hierarchical tree reflecting the drivers of SOC storage. It is oriented to be used by scientists in agronomy, forestry and soil sciences with the aim of uniformizing the description of practices influencing SOC in their original research. It is accessible in Agroportal (http://agroportal.lirmm.fr/ontologies/DATA4CPLUS) to enhance its findability, accessibility, interoperability and re-use by scientists and others such as laboratories or land managers. Future uses of the DATA4C+ thesaurus will be crucial to improve and enrich it, but also to raise the quality of meta-analyses on SOC, and ultimately help policy-makers to identify efficient agricultural and forest management practices to enhance SOC storage.

Abstract

Agroforestry systems have been much studied for their potential to store soil organic carbon (SOC). However, few data are available on their specific impact on potential SOC mineralization, especially at depth in subsoils. Moreover, many soils of the world, especially in arid and semi‐arid environments, also contain large stocks of soil inorganic carbon (SIC) as carbonates. Consequently, the organic carbon dynamics has been poorly investigated in these soils due to the complexity of measurements and of the processes involved. To assess mineralization rates of SOC with depth, we incubated soil samples coming from an 18‐year‐old agroforestry system (both tree row and alley) and an adjacent agricultural plot established on a calcareous soil in France. Soil samples were taken at four different depths: 0–10, 10–30, 70–100 and 160–180 cm. Total CO2 emissions, the isotopic composition (δ13C, ‰) of the CO2 and microbial biomass were measured. The SIC concentrations ranged from 48 to 63 g C kg−1 soil and the SOC concentrations ranged from 4 to 17 g C kg−1 soil. The contribution of SIC‐derived CO2 represented about 20% in the topsoil and 60% in the subsoil of the total soil CO2 emissions. The microbial biomass and the SOC‐derived CO2 emissions were larger in the topsoil, but the decomposition rates (day−1) remained stable with depth, suggesting that only the size of the labile carbon pool was modified with depth. Subsoil organic carbon seems to be as prone to decomposition as surface organic carbon. No difference in CO2 emissions was found between the agroforestry and the control plot, except in the tree row at 0–10 cm. Our results suggest that the measurement of soil respiration in calcareous soils could be overestimated if the isotopic signature of the CO2 is not taken into account. It also advocates more in‐depth studies on carbonate dissolution‐precipitation processes and their impact on CO2 emissions.

Abstract

Major drivers of gains or losses in soil organic carbon (SOC) include land management, land‐use change, and climate change. Thousands of original studies have focused on these drivers of SOC change and are now compiled in a growing number of meta‐analyses. To critically assess the research efforts in this domain, we retrieved and characterized 192 meta‐analyses of SOC stocks or concentrations. These meta‐analyses comprise more than 13,200 original studies conducted from 1910 to 2020 in 150 countries. First, we show that, despite a growing number of studies over time, the geographical coverage of studies is limited. For example, the effect of land management, land‐use change, and climate change on SOC has been only occasionally studied in North and Central Africa, and in the Middle East and Central Asia. Second, the meta‐analyses investigated a limited number of land management practices, mostly mineral fertilization, organic amendments, and tillage. Third, the meta‐analyses demonstrated relatively low quality and transparency. Lastly, we discuss the mismatch between the increasing number of studies and the need for more local, reusable, and diversified knowledge on how to preserve high SOC stocks or restore depleted SOC stocks.
