Some of these molecules affect tropospheric ozone and secondary aerosol formation and impact the atmospheric oxidation capacity on both regional and global scales. Other emissions undergo transport to the stratosphere, where they contribute to the halogen burden and influence ozone. The oceans also comprise a major sink for highly soluble or reactive atmospheric gases. These issues are an active area of research by the SOLAS (Surface Ocean Lower Atmosphere) community. This article provides a status report on progress over the past decade, unresolved issues, and future research directions to understand the influence of ocean biogeochemistry on gas-phase atmospheric chemistry. Common challenges across the subject area involve establishing the role that biology plays in controlling the emissions of gases to the atmosphere and the inclusion of such complex processes, for example involving the sea surface microlayer, in large-scale global models.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135358450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Our previous global ozone estimates for the Global Burden of Disease study corrected for bias uniformly across continents and then corrected near monitoring stations using the Bayesian Maximum Entropy (BME) framework for data fusion. Here, we use the Regionalized Air Quality Model Performance (RAMP) framework to correct model bias over a much larger spatial range than BME can, accounting for the spatial inhomogeneity of bias and nonlinearity as a function of modeled ozone. RAMP bias correction is applied to a composite of 9 global chemistry-climate models, based on the nearest set of monitors. These estimates are then fused with observations using BME, which matches observations at measurement stations, with the influence of observations declining with distance in space and time. We create global ozone maps for each year from 1990 to 2017 at fine spatial resolution. RAMP is shown to create unrealistic discontinuities due to the spatial clustering of ozone monitors, which we overcome by applying a weighting for RAMP based on the number of monitors nearby. Incorporating RAMP before BME has little effect on model performance near stations, but strongly increases R2 by 0.15 at locations farther from stations, shown through a checkerboard cross-validation. Corrections to estimates differ based on location in space and time, confirming heterogeneity. We quantify the likelihood of exceeding selected ozone levels, finding that parts of the Middle East, India, and China are most likely to exceed 55 parts per billion (ppb) in 2017. About 96% of the global population was exposed to ozone levels above the World Health Organization guideline of 60 µg m−3 (30 ppb) in 2017. Our annual fine-resolution ozone estimates may be useful for several applications including epidemiology and assessments of impacts on health, agriculture, and ecosystems.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136303643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Numerous smallholder farming systems remain, but most have shifted to industrial production. There is growing interest in agroecological transitions for smallholder farmers, but more attention needs to be paid to the challenges that may be encountered in the process. We conducted qualitative research in Sanliwan village in Shanxi Province because it represents the general dilemma facing smallholder farmers in China, and we compared our findings to those obtained in Sanggang village in Hebei Province because of its successful bottom-up experience in transitioning to agroecology. We found 4 challenges in the transition to agroecology in Sanliwan village: environmental degradation, the lack of direct markets, the need for more technical extension in agroecology, and farmer atomization. Bottom-up strategies for overcoming these challenges were identified in the case of Sanggang village. Notably, in the agroecological transition, the organization of smallholder farmers was a critical first step. From that point, smallholder farmers integrated internal resources and utilized external resources more efficiently to enhance environmental stewardship, improved technical extension in agroecology, and developed new markets. More research is needed to understand how top-down strategies can respond to such challenges and opportunities identified for bottom-up agroecological transitions.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135214222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

A persuasive body of literature suggests that children and youth can be and ought to be included in citizen science projects and that young people ought to and can have a greater say in their environmental and climate lives and futures. There is acknowledgment that certain populations, including young people, have been excluded from participation in citizen science, and strategies need to be developed to be more inclusive. Moreover, through inclusion of youth, there are opportunities for intergeneration collaboration leading to potential solutions.

Previous scholarship on genome editing in relation to African agriculture has focused on the technical capabilities of genome editing techniques and surveys of current research and development activities in this field. This article contextualizes and reflects critically on expectations that genome editing can or will deliver benefits for African scientists and farmers. The interviews reveal excitement around genome editing and anticipation for what it could achieve, but also a sober realism and frustration regarding the political-economic hurdles that constrain African scientists and research institutions and the generation of public goods for African farmers and societies. These insights, we show, challenge extant narratives related to genome editing and accessibility. As such, we center and interrogate the politics of knowledge surrounding the emergence of genome editing in Africa.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135494777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 argue that such an exploration should start by recognizing their weakness regarding the forces aiming at slowing down the pace of change. Recognizing this weakness should lead scientists to a change of tactics, embracing forms of strategic action used for centuries by groups on the weaker side of power struggles: that is, guerrilla strategies. Avoiding simplistic celebrations of guerrillas—historically a form of warfare that has produced as much pain as gain—an appraisal of some of its strategic tenets could help scientists to sketch alternative forms of engagement with the ecological crisis. Instead of grand gestures and direct confrontations, they could focus on carrying out epistemic strategic actions, or initiatives centered on the strategic usage of environmental knowledge and knowledge infrastructures to reduce, neutralize, and/or redress the impact of the organizations and regulations blocking, diverting, or slowing down decisive action regarding the ecological crisis. These actions could involve producing novel forms of knowledge, exposing facts that are currently hidden, refusing to engage in the production of contentious knowledge or, in extreme cases, disrupting specially damaging knowledge infrastructures.

Ante la gravedad de la crisis ecológica, científicos de distintas áreas se están preguntando qué más podemos hacer -además de aportar evidencia- para motivar procesos sustantivos de transformación socioambiental. En este artículo, sostenemos que la exploración de formas alternativas de acción debería empezar por reconocer la posición de debilidad de los científicos frente a las fuerzas que buscan ralentizar o frenar los procesos de transformación. Reconocer esta debilidad debería llevarnos a un cambio de táctica, adoptando formas de acción estratégica utilizadas durante siglos por grupos en el lado más débil de las luchas de poder: las guerrillas. Evitando una celebración simplista de la guerrilla -históricamente una forma de conflicto armado que ha producido más dolor que logros- analizamos cómo algunos de sus principios estratégicos nos pueden servir para desde las ciencias esbozar formas alternativas de acción en relación con la crisis ecológica. En lugar de declaraciones públicas y enfrentamientos directos, los científicos deberíamos desarrollar novedosas acciones epistémicas estratégicas, es decir, iniciativas centradas en el uso estratégico del conocimiento ambiental y sus infraestructuras para reducir, neutralizar y/o corregir el impacto de organizaciones y normativas que bloquean, desvían o ralentizan las transformaciones urgentes en relación con la crisis ecológica.

However, ships predominantly use fossil fuels for propulsion and electricity generation, which emit greenhouse gases such as carbon dioxide and methane, and air pollutants such as particulate matter, sulfur oxides, nitrogen oxides, and volatile organic compounds. The availability of Automatic Information System (AIS) data has helped to improve the emission inventories of air pollutants from ship stacks. Recent laboratory, shipborne, satellite and modeling studies provided convincing evidence that ship-emitted air pollutants have significant impacts on atmospheric chemistry, clouds, and ocean biogeochemistry. The need to improve air quality to protect human health and to mitigate climate change has driven a series of regulations at international, national, and local levels, leading to rapid energy and technology transitions. This resulted in major changes in air emissions from shipping with implications on their environmental impacts, but observational studies remain limited. Growth in shipping in polar areas is expected to have distinct impacts on these pristine and sensitive environments. The transition to more sustainable shipping is also expected to cause further changes in fuels and technologies, and thus in air emissions. However, major uncertainties remain on how future shipping emissions may affect atmospheric composition, clouds, climate, and ocean biogeochemistry, under the rapidly changing policy (e.g., targeting decarbonization), socioeconomic, and climate contexts.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135058862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Conventional leak detection and repair methods for fugitive methane emissions are labor-intensive and costly because they involve time-consuming close-range, component-level inspections at each site. This has prompted duty holders to examine new methods and strategies that could be more cost-effective. We examined a cooperative model in which multiple duty holders of upstream O&G sites in a region use shared services to inspect on-site equipment using optical gas imaging camera or Method 21. This approach was hypothesized to be more efficient and cost-effective than independent inspection programs by each duty holder in the region. To test this hypothesis, we developed a geospatial simulation model using empirical data from 11 O&G-producing regions in Canada and the United States. We used the model to compare labor cost, transit time, mileage, vehicle emissions, and driving risk between independent and co-op leak inspection programs. The results indicate that co-op leak inspection programs can generate relative savings in labor costs (1.8%–34.2%), transit time (0.6%–38.6%), mileage (0.2%–43.1%), vehicle emissions (0.01–4.0 tCO2), and driving risk (1.9%–31.9%). The largest relative savings and efficiency gains resulting from co-op leak inspection programs were in regions with a high diversity of duty holders, which was confirmed with simulations of fictitious O&G sites and road networks spanning diverse conditions. We also found reducing leak inspection time by 75% with streamlined methods can additionally reduce labor cost by 8.8%–41.1%, transit time by 5.6%–20.2%, and mileage by 2.60%–34.3% in co-op leak inspection programs. Overall, this study demonstrates that co-op leak inspection programs can be more efficient and cost-effective, particularly in regions with a large diversity of O&G duty holders, and that methods to reduce leak inspection time can create additional savings.","PeriodicalId":54279,"journal":{"name":"Elementa-Science of the Anthropocene","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136304609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
