The depth distribution of soil organic carbon (SOC) is governed by the interaction many ecosystem features, including differential C inputs in shallow and deep soils redistribution via water flow through profile. In C-rich Mollisols particular, we need to better understand degree which conversion native prairie cultivated lands changing loss retention. We probed multiple mechanisms driving these processes using two approaches: one leverages a regional-scale dataset derived from Natural Resources Conservation Service (USDA-NRCS) National Cooperative Soil Survey (NCSS) Characterization Database; second focusses on local-scale, more detailed representative climatic land-use gradients invoked larger database. first approach focused parameterizing SOC distributions across gradient US Midwest investigate how land use effective precipitation affects vertical SOC. furthered investigation drivers quantifying biological, physical, chemical properties profiles Kansas, US. declined gradually with as availability increased soils, prompting hypothesis that profile carries layers, particularly where high root abundances promote porosity.

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

This study addresses a notable gap in the climate change literature by examining potential of artificial intelligence and machine learning (AI–ML) urban adaptation sustainable development across major global continents. While much attention has been given to mitigation strategies, this uniquely delves into AI–ML’s underexplored role catalyzing contemporary future centers. The research thoroughly explores diverse case studies from Africa, Asia, Australasia, Europe, North America, South utilizing methodological framework involving six-step five-step models for systematic reviews. findings underscore AI–ML achievements, illuminate challenges, emphasize need context-specific collaborative approaches. imply that one-size-fits-all approach is insufficient. Instead, successful strategies must be intricately linked particular characteristics, vulnerabilities, intricacies each region. Furthermore, underscores importance international collaboration, knowledge sharing, technology transfer expedite integration globally. envisions promising trajectory domain, emphasizing necessity ongoing research, innovation, practical applications. As remains defining challenge, predicts an increasingly pivotal constructing climate-resilient centers promoting development. Continuous efforts advance technologies, establish robust policy frameworks, ensure universal access are crucial harnessing transformative capabilities combat consequences.

Cover crops are widely advocated for increasing soil organic carbon (SOC) levels, thereby benefiting health improvement and climate change mitigation. Few regional-scale studies have robustly explored SOC stocks under cover cropping, due to limited long-term experiments. We used the unique experimental data from North American Project Evaluate Soil Health Measurements conducted in 2019 address this issue. This study included 19 agricultural research sites with 36 pairs of cropping established between 1896 2014. Explanatory variables related site-specific environmental conditions management practices were collected identify prioritize contributing factors that affect crops, by coupling Boruta algorithm structural equation modeling. Overall, significantly (P < 0.05) improved several indicators health, including greater (concentration: +8%; stock: +7%), total nitrogen (+8%), water-stable aggregates (+15%), potential mineralization (+34%), on average, compared no crop control. Likewise, sequestered 3.55 Mg C ha-1 (0–15 cm depth), a sequestration rate 0.24 yr-1.
