We integrated a 20-year field experiment and laboratory measurements with three stable-isotope-enabled mechanistic models to examine SOC stocks and decomposition in a conventional corn–soybean system and two more diversified systems including small grains, legumes and manure inputs, in addition to corn and soybean. Contrary to the prevalent hypothesis that diversified systems increase SOC, we found no differences in 0.3 m topsoil or 1 m profile SOC and N stocks. Diversified systems markedly increased N mineralization rates and decomposition of older SOC from previous corn inputs. Models revealed that increased C decomposition with residence times of months to years counteracted higher C inputs but increased N supply. Our findings highlight a critical trade-off between C storage and N supply in these diversified systems, demonstrating that key climate benefits may arise from decreased N fertilizer use, not SOC sequestration. Sustainable and regenerative agriculture often employs diverse systems of crop rotation to reduce environmental impacts and sequester carbon. A long-term field study, however, reveals a trade-off between soil organic carbon storage and nitrogen supply.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 2","pages":"152-161"},"PeriodicalIF":25.7,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies suggest that bio-based products could mitigate the impacts of plastic pollution and that carbon emissions from the plastic sector could be reduced by using biomass as a plastic feedstock. Given the scale of plastic production, the resulting increase in biomass demand could induce detrimental land-use change at the global level. We use a spatially explicit land-system model to evaluate the land-use impact of bio-based plastic replacement up to the year 2040. At the global level, mitigating both plastic pollution and carbon emissions from the plastic sector could lead to a 22% increase in cropland expansion, a 35% increase in the area of cropland undergoing intensification and a 20% increase in deforestation relative to the baseline scenario. The amount and magnitude of land-use change depend on trade, technology and how alternative products are integrated into the plastics system. Decreasing plastic demand and production may prove a less risky strategy to mitigate the impacts of plastics. Bio-based plastics have gained attention as a potentially sustainable way to reduce fossil fuel-based plastic demand and store carbon. However, large-scale adoption of bio-based alternatives could have a substantial impact on land use, including deforestation.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 2","pages":"190-201"},"PeriodicalIF":25.7,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, disaggregating the compound effects of anthropogenic stresses on fluvial sediment transport at the global scale remains a challenge. Here we map the suspended sediment concentrations for global river channels, based on satellite observations, between 1985 and 2020, and estimate long-term changes in land–ocean sediment transfer. We find significant (P < 0.05) changes in suspended sediment concentrations in 67.8% (3.2 × 105 km) of the examined river channel length, with 43.4% (2.05 × 105 km) displaying a significant increasing trend, driven mainly by rising rainfall erosion and climate warming. Consequently, a global net increase (+0.58 Gt year−1) in land–ocean sediment flux has been observed over the past four decades, despite sediment trapping by recently constructed dams, mostly in Asia. Our study provides a new baseline for source-to-sink fluvial transport in the Anthropocene that can inform global water resource management and delta management and protection. Suspended sediments in river networks are a critical pathway for material and nutrient transport from land to the oceans, but global monitoring is challenging. Satellite records for the past three decades document an increase in sediment delivery, driven by climate and land-cover change.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 2","pages":"142-151"},"PeriodicalIF":25.7,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this Perspective, we highlight the potential of properly managed and incentivized perennial woody crops to support holistic sustainable development and urge scientists and policymakers to develop an effective agenda to better harness their benefits. Perennial woody crops are important sources of food that can provide ecosystem benefits through their long-lived nature and structural complexity.

Here we report a one-step dehydration–condensation method for the economical and green preparation of GR2Ms on a gram scale from biomass at room temperature under atmospheric pressure using only concentrated sulfuric acid. This protocol has been applied successfully to various types of biomass and carbohydrates, delivering a 33% mass yield of GR2M product. The properties of the product are consistent with those of classical reduced graphene oxide (RGO), with the twist that it does not need to be produced from graphite minerals. The mild reaction conditions substantially reduce the energy input, while providing a facile platform for monitoring the kinetics of RGO nucleation and growth. Compared with conventional methods, a 98% reduction in energy consumption is achieved. Overall, the results of this research pave a new avenue to scalable and sustainable GR2M production. Reduced graphene oxide materials are of great interest in many fields, but current production methods are neither sustainable nor scalable. Here the authors report a method that enables the facile production of reduced graphene oxide from biomass at ambient temperature.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 12","pages":"1699-1708"},"PeriodicalIF":25.7,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We reframe the responses to mitigating the world’s water crises using a ‘beyond growth’ framing and compare it to mainstream thinking. Beyond growth is systems thinking that prioritizes the most disadvantaged. It seeks to decouple economic growth from environmental degradation by overcoming policy capture and inertia and by fostering place-based and justice-principled institutional changes.

Here, we analyse the effects of deforestation-induced climate change on the soy–maize double cropping of the Cerrado biome. Since the 1980s, there has been an average delay of 36 days in the start of the agricultural rainy season, a 36.7% reduction in total rainfall over the period and a 1.5 °C rise in the temperature in the biome. Of the 8.1 million ha of soy–maize double cropping, 99% experienced delays in the agricultural rainy season and 61% faced reduced rainfall. Those changes have contributed to more frequent and severe soybean and maize crop shortfalls. Delays in the onset of the agricultural rainy season, reductions in rainfall and increases in maximum air temperatures occur more frequently in areas with extensive native vegetation loss. To sustain agricultural productivity in the Cerrado, it is crucial to conserve and restore its native vegetation. Deforestation has the potential to alter regional precipitation cycles. In the Cerrado biome, clearing of native vegetation has led to shortfalls of staple crops due to a delayed agricultural rainy season.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"8 1","pages":"34-43"},"PeriodicalIF":25.7,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
