“…These residues can result from agricultural practices in the field itself, as well as be derived from plants grown elsewhere. Starting with Jenny (1941), researchers have for decades gathered extensive data on the topic, not only in temperate climates but also in the tropics and arid regions (e.g., Bhattacharyya et al, 2021;Blet-Charaudeau et al, 1990;Gonzalez & Sauerbeck, 1982;Hans & Evans, 1957;Hénin et al, 1959;Hénin & Dupuis, 1945;Jenkinson, 1965Jenkinson, , 1971Jenkinson, , 1977Jenkinson, , 1990Jenkinson & Ayanaba, 1977;Jenkinson & Rayner, 1977;Ladd et al, 1985;Laudelout, 1993;Laudelout et al, 1960;Laudelout & Meyer, 1951;Mann, 1986;Poeplau et al, 2011;Smith et al, 1951;Smith et al, 2020;Soudi et al, 2020;Wiesmeier et al, 2020). The method of choice in much of this research has been to label organic matter isotopically with either 14 C or 13 C, then monitor the progressive decay of a single batch of that material over time after its incorporation into soils.…”

Over the last few years, the question of whether soil carbon sequestration could contribute significantly to climate change mitigation has been the object of numerous debates. All of these debates so far appear to have entirely overlooked a crucial aspect of the question. It concerns the short-term mineralization kinetics of fresh organic matter added to soils, which is occasionally alluded to in the literature, but is almost always subsumed in a broader modelling context. In the present article, we first summarise what is currently known about the kinetics of mineralization of plant residues added to soils, and about its modelling in the long run. We then argue that in the short run, this microbially-mediated process has important practical consequences that cannot be ignored. Specifically, since at least 90% of plant residues added to soils to increase their carbon content over the long term are mineralized relatively rapidly and are released as CO 2 to the atmosphere, farmers would have to apply to their fields 10 times more organic carbon annually than what they would eventually expect to sequester. Over time, because of a well-known sink saturation effect, the multiplier may even rise significantly above 10, up to a point when no net carbon sequestration takes place any longer.

“…Indeed, the soil carbon storage can be a more important determinant of climate impacts than above‐ground biomass (Yang & Tilman, 2020), and it largely depends on agricultural practice. Although mechanisms aiming at increasing short‐term production, such as ploughing, use of mineral fertilizers, or the push to use all available biomass, would seemingly result in increased carbon sequestration, those measures also lead to soil carbon depletion, depending on the procedure and environmental conditions (Bhattacharyya et al, 2021). The effect on soil carbon is often ignored in assessments though, also because a prediction of long‐term effects on soil is very difficult (Dash et al, 2019).…”

Does renewable mean good for climate? Biogenic carbon in climate impact assessments of biomass utilization

Using biomass to substitute fossil resources is seen as one of the sustainable ways to tackle climate change. Yet not all biomass projects can be a priori declared beneficial. A climate impact assessment, such as life cycle assessment or carbon footprint, is crucial for a science‐based policy recommendation. However, those assessments can often be incomplete, especially since many of those adopt an assumption that biogenic CO2 emissions cause no harm to the climate and do not need to be accounted. Such a simplistic “neutrality assumption” can lead to inaccurate results and thus to undesired consequences. This article synthesizes and further develops the diverse argumentation against the “neutrality assumption,” especially regarding the complexity of biomass production, differences in the timing of emission, allocation procedure, and climate change characterization methodology. Thus, the article draws a broader picture of the complex issue of biomass projects and argues for more comprehensive assessments.

“…Current ways of field engineering and management of agri-food systems (AFSs) are increasingly undermining environmental sustainability and human health through two main negative impacts: (a) the soil organic carbon (SOC) depletion-greenhouse gas (GHG) emission process (1) and (b) the poor-quality diet-based global nourishment. Many initiatives with worldwide-as well as regionalreach are addressing these impacts through the point of view of, for example, practices leading to soil carbon (C) enrichment; such is the case for the "Four per Thousand" initiative (2,3).…”

“…Nonetheless, to attribute nutrient dilution in edibles only to genetic improvement means to overlook other problems. On one hand, continuous agriculture has been inducing not only SOC stock depletion through C mineralization and respiration but also soil nutrient depletion, mainly in those areas where SOC stock in the top 100 cm layer concentrates only 50-100 t C ha -1 and agricultural systems have not adopted neither soil conservation practices (1,7) nor soil nutrient replacement through soil fertilization. On the other hand, the atmospheric CO 2 increase may have also contributed to this process (8): in a recent study, Chen et al (9) revealed that atmospheric CO 2 increase induced a mean annual gain in global primary productivity of 44 kg C ha -1 year -1 since the 2000s, contributing to the dilution of nutrients contained in food.…”

This work aims to contextualize and analyze the potential contribution of pecan to SDG2 under the dual perspective of carbon storage and human nutrition. Particularly, the study focuses on the pecan agroecosystems in the Americas, representing the most important pecan-producing countries (the United States, Mexico, Brazil, Argentina, Uruguay, and Peru). We observed that pecan is a reliable sink for storing atmospheric C and also for quality nuts with high nutritional density. The Americas, hold a population of ca. 23 M pecan trees, with the younger tree populations and the highest C-storing potential in South America. This pecan tree population has removed 51.3 Mt CO2eq immobilizing the OC in their aboveground biomass, but if the C sequestration for the whole system is considered, the value reaches nearly 80 Mt CO2eq. From a nutritional perspective, there are different dietary needs to cover according to the country, although the common analysis output is a low proportion of nuts in the diet, which is expected to improve, given the efforts of each country to promote domestic consumption. All the mentioned countries in this study have a low pecan consumption going from 8 to 293 g per capita yr-1, which in the light of the Global Burden of Disease represents 0.08 to 3.2% of the recommended yearly dietary basis for nuts overall. The inclusion of pecan nuts in the daily diet is of utmost importance to offset the food nutrient dilution carbohydrates-based, linked to the excess of atmospheric CO2. Also, pecan orchards function as a platform to integrate sustainable systems. The global benefit of having pecan and alley crops has been proved in regions other than the Americas with interesting economic outputs leading to energizing the life of rural communities. Pecan orchards and pecan agroforestry may lead to sustainable agri-food systems, with global gains in SOC and nutritional richness and diversity. Therefore, more in-depth studies are needed not only to fully understand the functioning of the systems at a productive level but also to design and plan sustainable landscapes in rural land.
