The decline of many wild bee species has major consequences for pollination in natural and agro-ecosystems. One hypothesized cause of the declines is pesticide use; neonicotinoids and pyrethroids in particular have been shown to have pernicious effects in laboratory and field experiments, and have been linked to population declines in a few focal species. We used aggregated museum records, ecological surveys and community science data from across the contiguous United States, including 178,589 unique observations from 1,081 bee species (33% of species with records in the United States) across six families, to model species occupancy from 1995 to 2015 with linked land use data. While there are numerous causes of bee declines, we discovered that the negative effects of pesticides are widespread; the increase in neonicotinoid and pyrethroid use is a major driver of changes in occupancy across hundreds of wild bee species. In some groups, high pesticide use contributes to a 43.3% decrease in the probability that a species occurs at a site. These results suggest that mechanisms that reduce pesticide use (such as integrative pest management) can potentially facilitate pollination conservation. Bees provide important pollination ecosystem services in agricultural landscapes, but the extent to which they are affected by pesticide use on a continental scale has yet to be explored. This study evaluates the impact of pesticide use on wild bee populations across the contiguous United States.

For as long as sustainable food systems have been on the global agenda, the meaning of ‘sustainable’ has been hotly debated. Discussing the use and abuse of the term sustainability in the food-system context, we select a specific case to illustrate this discussion, examine various sustainability arguments and propose ways forward for reduced meat aligned with local values and global needs. A contextual, transparent and nuanced debate can avoid policies informed by vested interests and straw-man arguments, which can backfire and hurt many of the very interests that the sector and policies aim to protect. In the midst of debates about climate and environmental impacts of meat, this Perspective uses Norway as a case study to frame a more holistic and nuanced approach to sustainable food production.

Direct recycling is a promising route for the sustainable management of end-of-life spent cathodes. However, its practical implementation is greatly restricted as most existing methods require heating or high-pressure conditions during the lithiation step to overcome the thermodynamic obstacles and realize lithium replenishment. In this study, we explored a strategy to realize spontaneous lithiation via simple solid–liquid mixing at ambient conditions. The thermodynamic barrier of the lithiation reaction was reduced by self-adsorbed amyloxylithium, which can spontaneously adsorb on the surface of degraded cathode particles without an external driving force. This strategy can regenerate both laboratory-dismantled LiNi0.6Co0.2Mn0.2O2 from 10 Ah pouch cells and industrial-dismantled LiNi0.5Co0.2Mn0.3O2 black mass. The capacity retention rate of a 1 Ah pouch cell assembled using regenerated LiNi0.5Co0.2Mn0.3O2 as cathode material was 80.5% after 500 cycles. The proposed strategy has big economic advantages over conventional pyro- and hydrometallurgical methods, as evidenced by the techno-economic analysis, accompanied by obvious environmental benefits, as evidenced by reduced CO2 emissions. This work provides a viable approach for the direct recycling of spent cathode material, improving the circularity of the battery industry. Direct recycling can facilitate the sustainable management of end-of-life spent cathodes, but is hindered by the harsh operation conditions required. An spontaneous lithiation strategy enables direct recycling of spent cathode material at ambient conditions, with clear economic and environmental benefits.

Human migration is both a consequence and a cause of environmental change. Related scientific and policy discourse focuses largely on international and urban migration, while rural migration receives far less attention. This is despite rural mobility being a key adaptive strategy for smallholders globally in the face of climate, environmental and social change. The integration of migration studies and land system science may serve to advance understanding of rural migration processes, and in turn advance the science of the fields themselves. Such efforts are relevant in an increasingly mobile world where new models and theory will be needed to meaningfully understand migration dynamics within sustainable socio-environmental systems. Migration has become a key research topic in recent years, but rural migration is relatively understudied despite the vast number of people and areas affected around the world. This Perspective lays out critical dimensions and dynamics that are worth examining.

Biodiversity protection and climate change mitigation require understanding of the potential trade-offs from possible future cropland expansion. Here we apply an interdisciplinary coupled modelling approach to identify areas under the globally highest expansion pressure of 1% to 30% future cropland expansion by 2030. On the basis of recent projections, we analyse the potential impacts on agricultural markets, biodiversity and CO2 land-use emissions of a 3.6% global cropland expansion scenario by 2030. We assess how global conservation policies could shift expansion pressure and alter the ensuing impacts. Our results confirm that the areas under pressure are located mainly in the tropics. A cropland expansion of 3.6% increases global agricultural production by 2%. The associated land-use change generates 17.1 Gt CO2 emissions and leads to a further decline in biodiversity intactness of 26% in the expanded areas. Conservation policies prohibiting the expansion into forests, wetlands and existing protected areas could substantially reduce emissions from land-use change, maintaining global agricultural productivity, but might have contrary effects on biodiversity. Strategic land-use planning could help reconcile agricultural production with environmental protection. The map of areas under expansion pressure presented here could contribute to improving the spatial planning of conservation measures. Understanding the various and multiple trade-offs of land-use changes and cropland expansion can contribute to more sustainable policies. A study explores future scenarios of cropland expansion along with the trade-offs in agricultural production and markets, biodiversity and CO2 emissions.

Marine bioprospecting, which involves the exploration of genetic and biochemical material from marine organisms, can be used towards addressing a broad range of public and environmental health applications such as disease treatment, diagnostics and bioremediation. Marine genetic resources are important reservoirs for such bioprospecting efforts; however, the extent to which they are used commercially for natural product discovery and the marine sources from which they are derived are not well understood. Here we introduce a comprehensive database of marine genes referenced in patent filings, the Marine Bioprospecting Patent database. It includes 92,550 protein-coding sequences associated with 4,779 patent filings, identified by analysing all relevant records from genetic sequence databases. Three companies alone—BASF, IFF and DuPont—included sequences from 949 species (more than half of referenced species with identified marine origin). Microbial life in the deep sea, a vast and remote biome predominantly beyond national jurisdiction, is already attracting substantial economic interest; the top ten patent holders have all filed marine gene patents referencing sequences from deep-sea life. Our findings provide an updated understanding of the marine bioprospecting landscape, contribute to the sustainable use of marine biodiversity and underscore the need for policymakers to ensure stewardship of deep-sea ecosystems. Marine genetic resources are important reservoirs for biodiscovery compounds that can help address public and environmental health challenges. This study presents a database and analysis on the commercial use of marine genetic resources towards the sustainable use of marine biodiversity.

The influence of international trade on the United Nations Sustainable Development Goals is multi-faceted. International trade can either promote or hinder progress, thus directly impacting people, economies and livelihoods. Here we explore the relevance of consumption-based proxies, which capture global demand for goods and services, to assess progress towards Sustainable Development Goals. We link these proxies to environmental and social issues for understanding trends in international outsourcing of resource and pollution-intensive production. We undertake a temporal assessment from 1990 to 2018 for the Global North and South to highlight polarizing trends that are affecting progress on achieving Sustainable Development Goals. We conclude that global trade can lead to both polarizing and equalizing trends that can influence a country’s ability to meet the 2030 Agenda for Sustainable Development. The role of international trade in achieving the UN Sustainable Development Goals is complex and affects multiple factors differently depending on the development context of each country. This study analyses historic trends and shows how global trade can either promote or hinder progress towards the Sustainable Development Goals.

Using nanoscale zero-valent iron (nFe0) materials for heavy metal removal is a viable approach for in situ groundwater pollution remediation. However, conventional nFe0 materials have indiscriminate reactivity towards various electron acceptors (for example, water) and just accumulate heavy metals onto the surface, which leads to poor selectivity and short longevity. Here we develop a lattice-sulfur-impregnated nFe0 (S-nFe0), achieving intraparticle sequestration of heavy metals enabled by a boosted Kirkendall-like effect. This metal-encapsulation approach outcompetes water for electrons and efficiently uses Fe-released spots, and the reacted S-nFe0 becomes inert to release metals (78–220× less than nFe0) in real groundwater matrices. The treated groundwater is estimated to meet drinking-water standards with a longevity of over 20–100 years. The synthesis of S-nFe0 has negligible environmental impacts according to Biwer–Heinzle environmental evaluation results. S-nFe0 also shows competitive production and operation costs for metal-contaminated groundwater remediation. Overall this work presents a strategy for achieving metal encapsulation in nFe0, which breaks the reactivity–selectivity–stability trade-offs of redox nanomaterials, providing a powerful tool to tackle groundwater pollution. Nanoscale zero-valent iron (nFe0) materials have a long history in groundwater pollution remediation but conventional nFe0 has intrinsic shortcomings. Here the authors develop a lattice-sulfur-impregnated nFe0 that enables efficient and selective heavy metal removal and long-term metal encapsulation.

Here the authors develop a lattice-sulfur-impregnated nFe0 that enables efficient and selective heavy metal removal and long-term metal encapsulation.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 10","pages":"1264-1272"},"PeriodicalIF":25.7,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487193","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}
