Global data on loss and damage used in research, policy and media primarily come from macrostatistics based on disaster inventories. Here, we propose a different approach, based on survey microdata. We harmonize data from 120,000 agricultural fields in six African countries for a period from 2008 to 2019 and quantify crop production losses related to climate shocks. We find substantial damages which affect around 35% of plots and reduce national crop production by 29% on average. The economic impacts are greater than the global disaster data suggest. The economic losses resulting from droughts and flood alone are US$5.1 billion higher than reported in disaster inventories, affecting between 145 and 170 million people. The difference stems mostly from smaller and less severe but frequent adverse events that go under-reported or undetected in disaster inventories and therefore elude macrostatistics and reporting. The findings have implications for measurement and policies related to loss and damage and disaster risk reduction. Estimating losses and damages caused by climate change is central to developing equitable climate policy. Microdata surveys have the potential to expose losses and damages among smallholder farmers that may otherwise be overlooked.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 11","pages":"1525-1534"},"PeriodicalIF":25.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672805","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}

Their urban sustainable development (USD) plans and policies cover a wide range of issues, such as biodiversity protection, transportation or poverty reduction. Yet, such policy-making may lack democratic legitimacy if these policies are out of step with the demands and concerns of residents. Considering this, the present study compares residents’ preferences about USD policy issues with the priorities set out in existing USD policy plans. We scrutinized the preferences of 5,800 residents across eight European cities through the application of survey experiments and simultaneously examined 166 existing USD policy plans from these cities and compared them with the survey results. Our findings indicate an on average high acceptance of USD (72.61%) but with substantial democratic discrepancies: while USD policy plans predominantly prioritize issues, such as biodiversity, education and transportation, residents expressed preferences for issues linked to their essential and everyday needs, such as cost of living, public health and poverty. These democratic discrepancies between residents’ priorities and the content of USD policy plans highlight the necessity of securing basic human needs as integral aspects of USD to foster a more profound and democratically supported urban socio-ecological sustainability transformation. This study finds that residents in European cities prioritize urban sustainable development policies that address basic human needs such as the cost of living and poverty alleviation, while existing policies focus more on issues such as biodiversity and public transport. These discrepancies suggest that sustainability policies may lack democratic legitimacy.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 11","pages":"1409-1418"},"PeriodicalIF":25.7,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01425-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672764","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}

These production disruptions will change with future warming, impacting consumers locally as well as remotely through supply chains. Due to a potentially nonlinear economic response, trade impacts are difficult to quantify; empirical assessments rather focus on the direct inequality impacts of weather extremes. Here, simulating global economic interactions of profit-maximizing firms and utility-optimizing consumers, we assess risks to consumption resulting from weather-induced production disruptions along supply chains. Across countries, risks are highest for middle-income countries due to unfavourable trade dependence and seasonal climate exposure. We also find that risks increase in most countries under future climate change. Global warming increases consumer risks locally and through supply chains. However, high-income consumers face the greatest risk increase. Overall, risks are heterogeneous regarding income within and between countries, such that targeted local and global resilience building may reduce them. It is hard to study weather-induced impacts on consumption as supply-chain effects cause a nonlinear economic response. Here consumption risks due to weather-induced production disruptions along supply chains are assessed considering income inequality within and across countries.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 11","pages":"1419-1428"},"PeriodicalIF":25.7,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41893-024-01430-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672776","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, exposure to pesticides such as neonicotinoids represents a major problem for bee health, necessitating strategies that can improve agricultural sustainability and pollinator health. Here we report a simple and scalable solution, through ingestible hydrogel microparticles (IHMs), which can capture neonicotinoids in vitro and in the bee gastrointestinal tract to mitigate the harmful effects of pesticides. Using the common eastern bumblebee (Bombus impatiens) as a model species and the neonicotinoid imidacloprid, we demonstrated by means of lethal and sublethal assays the substantial benefits of IHM treatments. Under lethal exposure of imidacloprid, bumblebees that received IHM treatment exhibited a 30% increase in survival relative to groups without IHM treatment. After a sublethal exposure of 5 ng, IHM treatment resulted in improved feeding motivation and a 44% increase in the number of bees that engaged in locomotor activity. Wingbeat frequency was significantly lower after a single 5 or 10 ng imidacloprid dose; however, IHM treatment improved wingbeat frequency. Overall, the IHMs improved bumblebee health, and with further optimization have the potential to benefit apiculture and reduce risk during crop pollination by managed bees. Bees are important components of sustainable agriculture through their pollination services, however, they are susceptible to pesticide toxicity. This study presents an ingestible hydrogel microparticle technology that can lessen the detrimental effects of toxicity from the imidacloprid pesticide.","PeriodicalId":19056,"journal":{"name":"Nature Sustainability","volume":"7 11","pages":"1441-1451"},"PeriodicalIF":25.7,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672789","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 showed that these measures generally reduced the bycatch while having no statistically significant effect on the target catch. Sensory-based measures generally outperformed physical-based ones in reducing the bycatch. Mitigation measures that worked well for several fishing gears or taxa, although useful, were very rare. Most of the adoptions by regional fisheries management organizations (59%) were supported by our findings, although many others are yet to be robustly evaluated. Our study encourages the innovation and adoption of technical measures and provides crucial insights for policy-making and further research in sustainable bycatch management.

In Brazil, this system involves maize being planted as a second crop following soybean to generate ethanol, thus allowing for combined food–energy production. However, the impacts of such production systems on several sustainable development goals (SDG) and associated indirect land-use changes have not yet fully been explored. We evaluate the fast-expanding food–energy system of double-cropped maize ethanol in the Central-West region of Brazil with respect to SDG impacts, combining life-cycle environmental and computable general equilibrium socio-economic models. We find that this system provides renewable and affordable energy (5 billion litres of ethanol, 600 GWh of electrical power) and feed (4 million tons of distillers dried grains), reduces greenhouse gas emissions (9.3 million to 13.2 million tCO2e), saves land (160,000 ha), boosts regional income and consumption, improves food security and benefits ecosystems and human health. Underlying drivers associated with this were the integration of feedstock supply into existing practices and the use of eucalyptus chips to provide process energy. The sustainability of this production system is improved further by carbon capture and storage. Combined food–energy production systems can help improve resource-use efficiency, but the extent to which such systems contribute to sustainable development has not yet been fully explored.

Here we apply a green and scalable process transforming cellulose to a robust electrolyte exhibiting lithium (Li) ion conductivity of 1.09 × 10−3 S cm−1 with a transference number of 0.81 and mechanical strength of 12 MPa. Our process takes advantage of the rich hydroxyl groups in the cellulose which are replaced by phthalic anhydride through an esterification reaction to form cellulose phthalate (CP). Combined experimental and theoretical analyses reveal that the introduction of phthalate groups is essential to not only ensure effective multi-oxygen interaction with Li ions to create fast ion transportation channels, but also facilitates the intermolecular hydrogen bond responsible for the impressive mechanical properties. The CP biopolymer film is even compatible with most commercial cathode materials, and our solid-state Li/CP/LiFePO4 cells show better performance and notably good stability over 1,000 cycles than that of a baseline Li-ion cell with a flammable organic liquid electrolyte. Our study unlocks the enormous potential of cellulose utilization in batteries and opens an avenue for the development of abundant and sustainable solid-state electrolytes. Cellulose is the most abundant renewable biopolymer resource in nature.
