We find widespread ADE across the TIX, well beyond previously studied archaeological sites, occupying at least 3–4% of the land area. We further estimate that the TIX may sequester 9 Mt of carbon within ADE deposits from past human inputs. Our findings show that ancient inhabitants of the TIX substantially modified their environment, highlighting the importance of conserving this natural and cultural resource given threats from climate change and deforestation. Past human land modification in the Amazon has resulted in nutrient- and carbon-rich soil deposits of great cultural and environmental value.

We find that China is making progress towards many of the sustainable development goals, but still insufficiently. The net-zero transition leads to substantial sustainability improvements, particularly in energy and water systems. However, the co-benefits alone cannot ensure a sustainable energy–food–water–air quality system. Moreover, uncoordinated policies may exacerbate threats to energy security and food security as variable renewables and bioenergy expand. We urge the implementation of pragmatic measures to increase incentives for demand management, improve food system efficiency, promote advanced irrigation technology and further strengthen air pollutant control measures. The net-zero transition will bring co-benefits to various sectors but also potential trade-offs that could undermine sustainable development efforts.

However, livestock are also key for food production and for livelihoods in some settings, and they can help preserve biodiversity and certain ecosystems. Previous studies have not yet fully explored sustainability limits to the use of grazing lands for food production in the context of biodiversity. Here we explore ‘biodiversity limits’ to grassland ruminant production by estimating the meat and milk production from domestic ruminants limited to grazing areas and stocking densities where livestock can contribute to the preservation or restoration of biodiversity. With biodiversity-friendly grazing intensities at 0–20% biomass removal depending on aridity, this take on biodiversity limits corresponds to 9–13% and 26–40% of the current grassland-based milk and meat production, respectively. This equals only 2.2 kg of milk and 0.8 kg of meat per capita per year, globally, but altered management and moving from meat-specialized to meat-and-dairy systems could increase the potential production while still remaining within this approach to biodiversity limits. Grazing lands make important contributions to society, including meat and milk, but there are sustainability limits to their use for production. This study explores milk and meat production from grazing ruminants within biodiversity limits.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 9","pages":"1160-1170"},"PeriodicalIF":25.7,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01398-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141802943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the nickel enrichment comes with larger volume change during cycling as well as reduced oxygen stability, which can both incur performance degradation. Here we show an ultrahigh-nickel cathode, LiNi0.94Co0.05Te0.01O2, that addresses all of these critical issues by introducing high valent tellurium cations (Te6+). The as-prepared material exhibits an initial capacity of up to 239 milliampere-hours (mAh) per gram and an impressive capacity retention of 94.5% after 200 cycles. The resulting Ah-level lithium metal battery with silicon-carbon anode achieves an extraordinary monomer energy density of 404 watt-hours (Wh) per kilogram with retention of 91.2% after 300 cycles. Advanced characterizations and theoretical calculations show that the introduction of tellurium serves to engineer the particle morphology for a microstructure to better accommodate the lattice strain and enable an intralayer Te–Ni–Ni–Te ordered superstructure, which effectively tunes the ligand energy-level structure and suppresses lattice oxygen loss. This work not only advances the energy density of nickel-based lithium-ion batteries into the realm of 400 Wh kg−1 but suggests new opportunities in structure design for cathode materials without trade-off between performance and sustainability. Increasing the Ni content to replace Co can increase the capacity and sustainability of cathode for batteries but leads to performance degradation issues. Here the authors address the structural and oxygen instabilities of Ni-rich cathodes by doping with tellurium.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 9","pages":"1204-1214"},"PeriodicalIF":25.7,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01402-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141811346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorporating depolymerizability and recyclability into luminescent polymers is pivotal for promoting their sustainability and minimizing their environmental impacts at the end of the product lifecycle, but existing strategies often compromise the light-emitting efficiencies. Here we develop a strategy that utilizes cleavable moiety to create depolymerizable and recyclable thermally activated delayed fluorescence (TADF) polymers without compromising their high light-emitting efficiencies. The electroluminescent devices based on the TADF polymers achieved a high external quantum efficiency of up to 15.1 %. The TADF polymers can be depolymerized under either mild acidic or heating conditions, with precise control of the kinetics, and the obtained pure monomers can potentially be isolated and repolymerized for subsequent life applications. This work promotes the end-of-life environmental friendliness and circularity of luminescent materials, paving the way to a sustainable photonic industry. Developing depolymerizable and recyclable polymers with high light-emitting efficiencies is of vital importance for sustainable photonic technologies, but remains challenging.

Specifically, with a ZnO catalyst decorated with single Ru atoms, methane first reacts with water to selectively produce methyl hydroperoxide via photocatalysis, followed by a thermodecomposition step yielding formaldehyde. Single Ru atoms, serving as electron acceptors, improve charge separation and promote oxygen reduction in photocatalysis. This reaction route with minimized energy consumption and high efficiency suggests a promising pathway for the sustainable transformation of light alkanes. Sustainable methane oxidation has the potential to green the petrochemical industry.

Most Si anode designs are nanostructured to overcome the large volume variation during cycling, but this comes at the expense of manufacturability, cost advantage and other merits. Here we demonstrate that micro-sized Si (μm-Si) recycled from photovoltaic waste can serve as anode material, exhibiting an average Coulombic efficiency of 99.94% and retaining 83.13% of its initial capacity after 200 cycles through the rational electrolyte design.

Responsible for the impressive electrochemical performance is a unique SEI chemistry where the flexible polymer-dominated outer layer well holds fractured Si particles together and the rigid Li2O/LiF-rich inner layer serves to facilitate ionic conduction and suppress side reactions. Our work not only suggests a more sustainable supply source for Si particles but also addresses the major problems facing μm-Si anode materials.
