Towards a global-scale soil climate mitigation strategy

Abstract Sustainable soil carbon sequestration practices need to be rapidly scaled up and implemented contribute climate change mitigation. We highlight that the major potential for is in cropland soils, especially those with large yield gaps and/or historic organic losses. The implementation of measures requires a diverse set options, each adapted local conditions management opportunities, accounting site-specific trade-offs. propose establishment information system containing localised on group, degradation status, crop gap, associated carbon-sequestration potentials, as well provision incentives policies translate options into region- soil-specific practices.

How to measure, report and verify soil carbon change to realize the potential of soil carbon sequestration for atmospheric greenhouse gas removal

Global Change Biology, Journal Year: 2019, Volume and Issue: 26(1), P. 219 - 241

Published: Aug. 30, 2019

Abstract There is growing international interest in better managing soils to increase soil organic carbon (SOC) content contribute climate change mitigation, enhance resilience and underpin food security, through initiatives such as ‘4p1000’ initiative the FAO's Global assessment of SOC sequestration potential (GSOCseq) programme. Since cannot be easily measured, a key barrier implementing programmes at large scale, need for credible reliable measurement/monitoring, reporting verification (MRV) platforms, both national emissions trading. Without investments could considered risky. In this paper, we review methods challenges measuring directly soils, before examining some recent novel developments that show promise quantifying SOC. We describe how repeat surveys are used estimate changes over time, long‐term experiments space‐for‐time substitution sites can serve sources knowledge test models, benchmark global frameworks change. briefly consider models simulate project examine MRV platforms already use various countries/regions. final section, bring together components described review, new vision framework change, support seeking effect way manage our soils.

A global meta-analysis of soil organic carbon in the Anthropocene

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: June 22, 2023

Anthropogenic activities profoundly impact soil organic carbon (SOC), affecting its contribution to ecosystem services such as climate regulation. Here, we conducted a thorough review of the impacts land-use change, land management, and change on SOC. Using second-order meta-analysis, synthesized findings from 230 first-order meta-analyses comprising over 25,000 primary studies. We show that (i) conversion for crop production leads high SOC loss, can be partially restored through management practices, particularly by introducing trees incorporating exogenous in form biochar or amendments, (ii) practices are implemented forests generally result depletion SOC, (iii) indirect effects wildfires, have greater than direct (e.g., rising temperatures). The our study provide strong evidence assist decision-makers safeguarding stocks promoting restoration. Furthermore, they serve crucial research roadmap, identifying areas require attention fill knowledge gaps concerning factors driving changes

Regenerative Agriculture—A Literature Review on the Practices and Mechanisms Used to Improve Soil Health

Sustainability, Journal Year: 2023, Volume and Issue: 15(3), P. 2338 - 2338

Published: Jan. 27, 2023

Conventional farming practices can lead to soil degradation and a decline in productivity. Regenerative agriculture (RA) is purported by advocates as solution these issues that focuses on health carbon sequestration. The fundamental principles of RA are keep the covered, minimise disturbance, preserve living roots year round, increase species diversity, integrate livestock, limit or eliminate use synthetic compounds (such herbicides fertilisers). overall objectives rejuvenate land provide environmental, economic, social benefits wider community. Despite RA, vast majority growers reluctant adopt due lack empirical evidence claimed profitability. We examined reported mechanisms associated with against available scientific data. literature suggests agricultural such minimum tillage, residue retention, cover cropping improve carbon, crop yield, certain climatic zones types. Excessive chemicals biodiversity loss ecosystem degradation. Combining livestock agroforestry same landscape several co-benefits. However, vary among different agroecosystems may not necessarily be applicable across multiple agroecological regions.

Climate change and ensuring food security for an exponentially growing global human population are the greatest challenges future agriculture. Improved soil management practices crucial to tackle these problems by enhancing agro-ecosystem productivity, fertility, carbon sequestration. To meet Paris climate treaty pledges, must address validated approaches sequestration stabilization. The present synthesis assesses a range of current potential agricultural (AMP) that have effect on organic (SOC) storage Through two strategies—increasing inputs (e.g., enhanced primary production, fertilizers) reducing SOC losses erosion, managing respiration)—AMP can either sequester, up 714 ± 404 (compost) kg C ha−1 y−1, having no distinct impact (mineral fertilization), or even reduce stocks in topsoil (bare fallow).

Not only do soils provide 98.7% of the calories consumed by humans, they also numerous other functions upon which planetary survivability closely depends. However, our continuously increasing focus on for biomass provision (food, fiber, and energy) through intensive agriculture is rapidly degrading diminishing their capacity to deliver vital functions. These tradeoffs in soil functionality – increased one function at expense critical are this review. We examine how land-use change has decreased ability regulate carbon pool thereby contribute profoundly climate change, cycle nutrients that sustain plant growth ecosystem health, protect biodiversity many depend, Earth's freshwater supplies. decreasing these can be halted reversed.

Soil Organic Carbon Sequestration after Biochar Application: A Global Meta-Analysis

Biochar application to soil has the potential sequester carbon in long term because of its high stability and large-scale production potential. However, biochar technologies are still relatively new, global factors affecting long-term fate environment poorly understood. To fill this important research gap, a meta-analysis was conducted including 64 studies with 736 individual treatments. Field experiments covered experimental durations between 1 10 years amounts 100 Mg ha−1. They showed mean increase organic (SOC) stocks by 13.0 ha−1 on average, corresponding 29%.
