Résumé :

One of the most important ways to reduce atmospheric carbon is the carbon sequestration by trees. Chestnut-leaved oak (Quercus castaneifolia C. A. Mey) is one of the most important native oaks of Iran distributed in the Hyrcanian Forests. The pure and mixed stands of it cover about 6.5% of these forests. In this study, carbon sequestration of chestnut-leaved oak seedlings was evaluated by using some morphological characteristics of the root and shoot. For this purpose, one hundred seedlings were sampled by method of Systematic-Random from the sowing bed on March 2022 in the Pylambra nursery at

Résumé :

Forage crops are widely grown in the mixed cropping system of southwestern Uruguay. There is renewed interest in the use of forages for soil improvement and carbon sequestration, but the root growth of forages has received little study. Field observations were made of the root systems of tall fescue (Festuca arundinacea Schreb.), alfalfa (Medicago sativa L.) and chicory (Cichorium intybus L.). Soil core samples were used to measure root count and biomass distributions to a depth of 1 m. Roots were detected to a depth of 1 m for all species, although half of the root biomass for each species wa

Résumé :

Soil is the largest carbon pool in terrestrial ecosystems, and it is particularly important to study soil carbon pools. In this study, we investigated the effects of intensive agriculture, plant inputs and organic matter inputs on the soil organic carbon pool, and the results showed that intensive agriculture increased the soil carbon pool and soil organic matter content to a certain extent, and increased the rate of carbon sequestration in the soil, but intensive agriculture made the soil more prone to erosion, resulting in the loss of soil nutrients; the plant inputs were mainly in the form

Résumé :

Abstract To achieve the challenges raised in Agenda 2063 and the Malabo Declaration, new agricultural techniques need to be promoted. Practical approaches to implement climate smart agriculture and sustainable agriculture, able to deliver at field level, are required. These include sustainable soil and land management that allows different user groups to manage their resources, including water, crops, livestock and associated biodiversity, in ways that are best suited to the prevailing biophysical, socio-economic and climatic conditions. The adoption of locally adapted sustainable soil management practices is needed to support climate change mitigation and adaptation from the agricultural perspective. In this sense, Conservation Agriculture (CA) can be adapted to local conditions, and help achieve the key objectives. The application of CA principles brings multiple benefits, especially in terms of soil conservation, but also for mitigating climate change. In fact, CA has the ability to transform agricultural soils from being carbon emitters into carbon sinks, because of no-tillage (NT) techniques and the return to the soil of diverse crop biomass from above-ground parts of plants and from diverse roots systems and root exudates. Similarly, fossil energy use decreases due to the reduction in agricultural operations, and so less CO<sub>2</sub> is emitted to the atmosphere. Lower greenhouse gas (GHG) emissions in CA also result, because of reduced and more efficient use of inputs. Scientific studies confirm the sequestration potential of increased soil organic carbon (SOC) stocks on croplands in Africa on each of the continent's major bioclimatic areas. Coefficients of SOC sequestration for Africa are presented in this chapter.

Résumé :

Abstract Boreal forests sequester and store large amounts of carbon both above and below ground. Forest management could influence carbon storage. Differences between upland soils and peatlands are important. In peatlands, large amounts of carbon are stored in the peat, making them more susceptible to differences in forest management. On peatlands, carbon balance is mostly determined by groundwater levels. Carbon storage on both upland and peat soils depends on harvest intensity since most carbon losses, apart from harvested forest products, come from decomposition of roots and logging residues. Scales in both space and time are both important considerations when estimating the effect on carbon balances.

Texte intégral

Résumé :

AbstractThe fungi in Glomeromycota are mutualistic symbionts of plant roots and produce a special glycoprotein called “glomalin” on their spores and mycelium cell wall. The glomalin enters adjacent soil after cell wall death and decomposition. It contains 3–5% nitrogen and 36–59% carbon with considerable amounts of iron (0.8–8%). Glomalin is considered a recalcitrant source of carbon. The half-life of glycoprotein is approximately 50 years, so it has a relatively long persistence in soil. Therefore, it could contribute to the sequestration of carbon in land-based ecosystems. The rate of carbon flow from the plant to the underground parts and then to the fungal symbionts affects the amount of glomalin synthesis by the fungi. The impact of different environmental factors such as nutrient availability, tillage, atmospheric CO2 level, drought, salinity, and heavy metal toxicity stresses on carbon allocation to the fungi and its consequence on the amount of glomalin production are addressed here. Also, the contribution of glomalin in carbon sequestration in soils is discussed.

Résumé :

AbstractHigh temperature stress is a primary constraint to maximal yield in wheat, as in nearly all cultivated crops. High temperature stress occurs in varied ecoregions where wheat is cultivated, as either a daily chronic metabolic stress or as an acute episodic high heat shock during critical periods of reproductive development. This chapter focuses on defining the key biochemical processes regulating a plant’s response to heat stress while highlighting and defining strategies to mitigate stress and stabilize maximal yield during high temperature conditions. It will weigh the advantages and disadvantages of heat stress adaptive trait breeding strategies versus simpler integrated phenotypic selection strategies. Novel remote sensing and marker-assisted selection strategies that can be employed to combine multiple heat stress tolerant adaptive traits will be discussed in terms of their efficacy. In addition, this chapter will explore how wheat can be re-envisioned, not only as a staple food, but also as a critical opportunity to reverse climate change through unique subsurface roots and rhizomes that greatly increase wheat’s carbon sequestration.

This chapter examines the potential impacts of climate change on the Acadian forest. Bill McKibben’s book End of Nature warned of the possibility of losing northern New England’s spruce-fir forests unless strong measures to reduce carbon emissions were swiftly taken. The Northern Forest Lands Study noted that forests can play an important role in sequestering and storing carbon. Forest researchers advise that older, unmanaged forests store the most carbon, while intensive management (clear-cuts and whole-tree harvests) release carbon. Conservation science and climate science agree on the need for large, unmanaged forest reserves to preserve habitat and to optimize carbon sequestration for long-term carbon storage in live trees and forest soils.

Résumé :

Carbonate-containing minerals comprise an additional form of soil carbon known as soil inorganic carbon (SIC). Though SIC stocks are large, they been disregarded in most studies to carbon sequestration. After reviewing the main forms of SIC (geogenic, biogenic and pedogenic carbonates) and the chemical processes leading to formation of pedogenic carbonates, we review the importance of SIC in the global C cycle and ecosystem functions. Besides pH regulation, SIC and dissolved Ca2+ from carbonates dissolution: i) increase plant growth due to better root growth, nutrient availability and acquisition, as well as provide protection against pathogens; ii) increase activities of soil microorganisms mineralizing nutrients; and iii) bind organic compounds which, consequently, stabilize organic matter, produce larger and stable aggregates, and control water permeability and balance. Consequently, the SIC is crucial not only for pH regulation, but also strongly contributes to many other soil functions and health. Finally, we assess future SIC losses under anticipated global change processes such as increased N deposition and fertilization, elevated CO2, invasive plant distribution and climate change. These SIC losses damage soil functionality and make it more vulnerable to a broad range of degradation factors, including erosion, topsoil and subsoil compaction, acidification and nutrient depletion. Crucial is that in contrast to organic carbon, the SIC losses are irrecoverable. We conclude that SIC is an important soil constituent responsible for a broad range of physical, chemical and biological soil properties and processes as well as ecosystem services such as cycles of C, N and other elements.

Texte intégral

Résumé :

Environmental degradation and climate change are key current threats to world agriculture and food security and human–induced changes have been significant driving forces of this global environmental change. An important component is land degradation which results in a diminished soil organic carbon (SOC) stock with concomitant loss of soil condition and function. Land management to improve soil organic matter content, condition and productivity is therefore a key strategy to safeguard agricultural production, food supply and environmental quality. Soil organic carbon sequestration through the use of plant species with high photosynthetic efficiency, deep roots and high biomass production is one important strategy to achieve this. Tropical pastures, which are adapted to a wide range of environmental conditions have particular potential in this regard and have been used extensively for land rehabilitation. Tropical pastures also have advantages over trees for biomass and carbon accumulation due to their rapid establishment, suitability for annual harvest, continual and rapid growth rates. In addition, tropical pastures have the potential for SOC storage in subsoil horizons due to their deep root systems and can be used as biomass energy crops, which could further promote their use as a climate change mitigation option. Here we aimed to review current knowledge regarding the SOC storage potential of tropical grasses worldwide and identified knowledge gaps and current research needs for the use of tropical grasses in agricultural production system.

Texte intégral

Résumé :

Organic fertilizers can serve as an element of transitions to sustainable low-input agriculture in semi-arid regions of the MENA region. They play a key role in supporting soil biota and soil fertility. Yield improvements, availability and relatively low costs make organic fertilizers an attractive alternative for farmers. In semi-arid regions, important considerations are improved soil quality, which in turn affects soil water retention, while better root development helps crops resist heat and water stress. Organic fertilizers thus support climate adaptation and regional food security. Soil quality is crucial for carbon sequestration, at the same time that increased nutrient retention reduces impacts of agricultural runoff on groundwater and water bodies. Factors that impede the generalised use of organic fertilizers include lack of expertise, subsidy structures, constraints of the wider food and agricultural systems, and difficulties in transitioning from conventional agriculture. Such obstacles are aggravated in countries affected by security issues, financial volatility or restrictions in access to market. Against the background of both general and local constraints, the chapter examines possible pathways to benefit from organic fertilizers, in particular synergies with other sustainable agricultural practices, as well as improved access to expertise.

Abstract In the face of escalating global climate challenges, Carbon Capture, Utilization, and Storage (CCUS) emerges as a pivotal technology in the quest to mitigate atmospheric CO2 emissions. Among the various geological formations suitable for CO2 sequestration, coal seams represent a unique and promising option, especially those that are unmineable due to depth, thickness, or other economic constraints. The success of this formation is closely tied to the intricate interactions among CO2, coal, and in-situ fluids, with wettability playing a crucial role. A deep understanding of wettability

Résumé :

Abstract In Geological Carbon Sequestration (GCS), mineralization is a secure carbon dioxide (CO2) trapping mechanism to prevent possible leakage at later stage of the GCS project. Modeling of the mineralization during GCS relies on numerical reservoir simulation, but the computational cost is prohibitively high due to the complex physical processes. Therefore, deep learning (DL) models can be used as a computationally cheaper and at the same time, reliable alternative to the conventional numerical simulators. In this work, we have developed a DL approach to effectively predict the dissolution

Résumé :

AbstractIron sulfide scale is found almost ubiquitously in maturing oilfield produced water handling and injection systems. Keeping injection systems clean of sulfide scale is becoming more of a shared challenge, but there are few examples where true root cause analysis has led to specific laboratory testing and development of bespoke removal and prevention methods. This paper aims to link these aspects by sharing the best practices from around the world with cutting edge techniques and chemistries used to maintain flow assurance and injectivity in produced water handling systems affected by i

Résumé :

Abstract Naturally fractured reservoirs (NFRs), such as fractured carbonate reservoirs, are commonly located worldwide and have the potential to be good sources of long-term storage of carbon dioxide (CO2). The numerical reservoir simulation models are an excellent source for evaluating the likelihood and comprehending the physics underlying behind the interaction of CO2 and brine in subsurface formations. For various reasons, including the rock's highly fractured and heterogeneous nature, the rapid spread of the CO2 plume in the fractured network, and the high capillary contrast between matri

Résumé :

Abstract Southeast Asia is increasingly gaining attention as a promising geological site for permanent CO2 sequestration in deep saline aquifers. During CO2 injection into saline reservoirs, the reaction between injected CO2, the resident formation brine, and the reservoir rock could cause injectivity change due to salt precipitation, mineral dissolution, and fine particles migration. The underlying mechanisms have been extensively studied, both experimentally and numerically and the governing parameters have been identified and studied. However, the current models that have been widely adopte

Résumé :

Abstract CO2 Interfacial Tension (IFT) and the reservoir rock-fluid interfacial interactions are critical parameters for successful CO2 geological sequestration, where the success relies significantly on the rock-CO2-brine interactions. IFT behaviors during storage dictate the CO2/brine distribution at pore scale and the residual/structural trapping potentials of storage/caprocks. Experimental assessment of CO2-Brine IFT as a function of pressure, temperature, and readily available organic contaminations on rock surfaces is arduous because of high CO2 reactivity and embrittlement damages.
