As global environmental changes continue to accelerate, research and practice in the field of conservation biology may be essential to help forestall precipitous declines in the earth’s ability to sustain a diversity of life. However, many conservation programs have faced scrutiny for the social injustices they create, especially within the paradigm of demarcating protected lands. Currently, a new conservation paradigm emphasizing landscapes shared by people and wildlife is emerging, and with it, an opportunity to ensure that justice for both human and beyond-human groups is given consideration. Here, we examine a practice emblematic of this new conservation paradigm, the reintroduction and recovery of large carnivore species, and draw from theories in environmental justice to detail the many forms of justice at stake in these efforts. Our analysis shows that a pluralistic application of justice is required to ensure that new conservation practices do not produce and reproduce injustices for people. In addition, we show that the success of these emerging programs in meeting their conservation goals in fact depends on meaningfully addressing a range of justice concerns. By developing this framework, we also identify domains in which environmental justice scholarship can expand its scope. To this end, we introduce the novel concept of affective environmental justice, which describes the complex role of emotions as environmental harms, as disruptors of understanding other forms of justice, and as links between logics of oppression. Our framework offers a comprehensive resource to work through in planning and implementing large carnivore reintroduction and recovery programs, and we conclude by describing the challenges and opportunities for further aligning conservation and environmental justice in research and practice.

Transparent exopolymer particles (TEP) and Coomassie stainable particles (CSP) are gel-like particles, ubiquitous in the ocean, that affect important biogeochemical processes including organic carbon cycling by planktonic food webs. Despite much research on both groups of particles (especially TEP) over many years, whether they exist as distinctly stainable fractions of the same particles or as independent particles, each with different driving factors, remains unclear. To address this question, we examined the temporal dynamics of TEP and CSP over 2 complete seasonal cycles at 2 coastal sites in the Northwestern Mediterranean Sea, the Blanes Bay Microbial Observatory (BBMO) and the L’Estartit Oceanographic Station (EOS), as well as their spatial distribution along a coast-to-offshore transect. Biological, chemical, and physical variables were measured in parallel. Surface concentrations (mean ± standard deviation [ SD ]) of TEP were 36.7 ± 21.5 µg Xanthan Gum (XG) eq L –1 at BBMO and 36.6 ± 28.3 µg XG eq L –1 at EOS; for CSP, they were 11.9 ± 6.1 µg BSA eq L –1 at BBMO and 13.0 ± 5.9 µg BSA eq L –1 at EOS. Seasonal variability was more evident at EOS, where surface TEP and CSP concentrations peaked in summer and spring, respectively, and less predictable at the shore-most station, BBMO. Vertical distributions between surface and 80 m, monitored at EOS, showed highest TEP concentrations within the surface mixed layer during the stratification period, whereas CSP concentrations were highest before the onset of summer stratification. Phytoplankton were the main drivers of TEP and CSP distributions, although nutrient limitation and saturating irradiance also appeared to play important roles. The dynamics and distribution of TEP and CSP were uncoupled both in the coastal sites and along the transect, suggesting that they are different types of particles produced and consumed differently in response to environmental variability.

As an emerging contaminant, rare earth elements (REEs) are becoming an environmental concern, especially in Chinese cities. This study investigated the distribution of REEs in river water and tap water samples in Guiyang, Southwest China. In all water samples, the concentrations of total dissolved REE (∑REE) ranged from 15.1 to 53.3 ng·L –1 , with the heavy rare earth elements enriched than the light rare earth elements. Most of the water samples showed significant positive Gd anomalies, with the highest abnormal value calculated to be 29.23. The main reason for the positive Gd anomalies was found to be the release of medical wastewaters containing Gadopentetic acids (Gd-DTPA). Overall, anthropogenic Gd could contributed >60% of total Gd in river waters and tap waters. Because Gd-DTPA is commonly used in large Chinese hospitals, the results of this study implied that anthropogenic Gd release could be common in Chinese cities.

Due to the rapid urbanization process, the consumption of trace and rare earth elements has dramatically increased. Although some elements have been extensively studied due to their high biological toxicity, most elements are ignored and taken seriously in recent years. Here, we investigated the urban geochemistry, source, and anthropogenic responding factor for 15 trace elements (Cd, Pb, Co, Sn, Cu, Ni, V, As, Mo, Sb, Al, Li, Fe, Zn, and Sr) and rare earth elements in surface water of the Suzhou city. The percentage of anthropogenic gadolinium vary from 46.9% (YCH-2) to 92.8% (WS-2), while the analysis of variance shows that human activities may affect the distribution of Cd, Co, Sn, Ni, As, Li, Fe, and Sr. Three clusters are obtained from the correlation and cluster analysis. The Cluster 1 with a significant positive correlation of Pb, Cd, Gd, Li, Sr, Co, Fe, Ni, and Sn reflecting these elements are dominantly influenced by urban sewage and industrial activities. The Cluster 2 (Zn, Cu, and Al) can be attributed to geologic sources, while the Cluster 3 (V, Mo, As, and Sb) indicate the combined action of agricultural and urban activities. The Gd versus Li plot showed a significant positive correlation, which can be used as a new indicator to trace the anthropogenic impact on urban waters. Overall, this study provides clear evidence that the content and distribution of Gd and Li are deeply affected by human activities in a high-tech industrial city (Suzhou), which can be regarded as emerging elements contaminations.

Global bottom-up and top-down estimates of natural, geologic methane (CH 4 ) emissions (average approximately 45 Tg yr –1 ) have recently been questioned by near-zero (approximately 1.6 Tg yr –1 ) estimates based on measurements of 14 CH 4 trapped in ice cores, which imply that current fossil fuel industries’ CH 4 emissions are underestimated by 25%–40%. As we show here, such a global near-zero geologic CH 4 emission estimate is incompatible with multiple independent, bottom-up emission estimates from individual natural geologic seepage areas, each of which is of the order of 0.1–3 Tg yr –1 . Further research is urgently needed to resolve the conundrum before rejecting either method or associated emission estimates in global CH 4 accounting.

Although studies of biogeochemical processes in polar sea ice have been increasing, similar research on relatively warm low-salinity sea ice remains sparse. In this study, we investigated biogeochemical properties of the landfast sea ice cover in the brackish Bothnian Bay (Northern Baltic Sea) and the possible role of this sea ice in mediating the exchange of greenhouse gases, including carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous oxide (N 2 O) across the water column–sea ice–atmosphere interface. Observations of total alkalinity and dissolved inorganic carbon in both landfast sea ice and the water column suggest that the carbonate system is mainly driven by salinity. While high CH 4 and N 2 O concentrations were observed in both the water column (up to 14.3 and 17.5 nmol L –1 , respectively) and the sea ice (up to 143.6 and 22.4 nmol L –1 , respectively), these gases appear to be enriched in sea ice compared to the water column. This enrichment may be attributable to the sea ice formation process, which concentrates impurities within brine. As sea ice temperature and brine volume decrease, gas solubility decreases as well, promoting the formation of bubbles. Gas bubbles originating from underlying sediments may also be incorporated within the ice cover and contribute to the enrichment in sea ice. The fate of these greenhouse gases within the ice merits further research, as storage in this low-salinity seasonal sea ice is temporary.

Iron (Fe) has been shown to limit growth of marine phytoplankton in the Southern Ocean, regulating phytoplankton productivity and species composition, yet does not seem to limit primary productivity in Antarctic sea ice. Little is known, however, about the potential impact of other metals in controlling sea-ice algae growth. Here, we report on the distribution of dissolved and particulate cadmium (Cd), cobalt (Co), copper (Cu), manganese (Mn), nickel (Ni), and zinc (Zn) concentrations in sea-ice cores collected during 3 Antarctic expeditions off East Antarctica spanning the winter, spring, and summer seasons. Bulk sea ice was generally enriched in particulate metals but dissolved concentrations were similar to the underlying seawater. These results point toward an environment controlled by a subtle balance between thermodynamic and biological processes, where metal availability does not appear to limit sea-ice algal growth. Yet the high concentrations of dissolved Cu and Zn found in our sea-ice samples raise concern about their potential toxicity if unchelated by organic ligands. Finally, the particulate metal-to-phosphorus (P) ratios of Cu, Mn, Ni, and Zn calculated from our pack ice samples are higher than values previously reported for pelagic marine particles. However, these values were all consistently lower than the sea-ice Fe:P ratios calculated from the available literature, indicating a large accumulation of Fe relative to other metals in sea ice. We report for the first time a P-normalized sea-ice particulate metal abundance ranking of Fe >> Zn ≈ Ni ≈ Cu ≈ Mn > Co ≈ Cd. We encourage future sea-ice work to assess cellular metal quotas through existing and new approaches. Such work, together with a better understanding of the nature of ligand complexation to different metals in the sea-ice environment, would improve the evaluation of metal bioavailability, limitation, and potential toxicity to sea-ice algae.

The current IPCC landfill methane (CH 4 ) methodology excludes critical process drivers now known to control emissions. These include site-specific (1) operational factors (i.e., thickness and composition of various cover soils; physical extent of engineered biogas recovery) and (2) temporal climate effects on soil moisture/temperature profiles in each cover which, in turn, drive gaseous transport, microbial methanotrophic oxidation, and temporally variable “net” CH 4 emissions over an annual cycle. Herein, we address the international field validation and application of a process-based model CA lifornia L andfill M ethane I nventory M odel (CALMIM) which encompasses site-specific climate, cover soils, engineered biogas recovery, and other site-specific strategies. Using embedded soil microclimate models with (a) default 30-year climate data, (b) site-specific annual weather data, or (c) future climate predictions (i.e., CMIP5), the transient soil moisture and temperature effects on bidirectional diffusive CH 4 /oxygen transport and microbial oxidation can be estimated for any cover soil at any global location. We focus on site-specific field data comparisons to CALMIM-predicted annual and monthly CH 4 emissions both without and without methanotrophic oxidation. Overall, 74% of 168 individual surface CH 4 emission measurements across 34 international sites were consistent with CALMIM-modeled annual predictions with oxidation (+ or – SD ). Notably, the model overpredicted 30 comparisons and underpredicted 13 comparisons. In addition to improving site-specific landfill CH 4 inventories, we address how this freely available tool can be used to (a) recommend site-specific cover soil modifications to minimize emissions; (b) systematically compare the spatial and temporal variability of emissions for diverse global locations, latitudinal gradients, extreme climates, and future climate scenarios; (c) assist scheduling of field campaigns to capture seasonal variability; and (d) provide a 12-month annual framework with average monthly CH 4 emission statistics for comparison to periodic temporal results from diverse bottom-up and top-down field techniques with variable uncertainties. Importantly, CALMIM does not require intensive site-specific model calibrations.

The co-creation of knowledge is gaining recognition and use within the science, practice, and movement of agroecology. Knowledge co-creation fosters participatory learning and development, which differs from passive knowledge sharing. This approach can bridge the real and perceived gaps across diverse forms of knowledge, including what is often distinguished as farmers’ traditional, Indigenous, tacit, or local knowledge and experts’ scientific, western, or generalizable knowledge. Formal academic documentation of processes and outcomes related to knowledge co-creation is limited; therefore, we bring in examples of published research, drawing from fields of agroecology, participatory action research, and science and technology studies, along with a firsthand farmer perspective on co-creation. Combined, these frameworks offer insight into the potential benefits of knowledge co-creation in agroecology. Many of these challenges, such as navigating power dynamics, may be addressed through mindful research and community practices, including strong communication and transparent expectations and goals. Co-creation processes have traditionally and continually taken place between farmers and throughout communities without academic acknowledgment and/or interpretation of such. We reinstate the invaluable role of farmer-centered inquiry, understanding, and application, which offer benefits to individual farmers and their extended communities of practice and research, in addition to holding spiritual and cultural significance. The co-creation of knowledge in agroecology presents a compelling, adaptive approach and outcome for the increasingly complex challenges facing farmers and the agrifood system.

This article offers a framework for evaluating agroecological principles, practices, and claims. Advocates of agroecology offer principles for sustainable, productive, and efficient agricultural systems. The evaluation question that immediately and inevitably arises in the face of such claims is: Does agroecology work? Thus do 2 fields of inquiry intersect: evaluation and agroecology. But there are many approaches to and models of evaluation. The challenge is to match the evaluation framework to the nature of agroecology. Because agroecology is based on principles, the appropriate evaluation approach is principles-focused evaluation. This article (1) elucidates principles-focused evaluation and demonstrates its relevance to evaluating agroecological practices and claims, (2) offers a principles-focused evaluation framework for monitoring agroecological transition and intensification within a particular context, and (3) concludes with lessons about principles-focused evaluation from agroecology.

Asia has been experiencing rapid industrialization, urbanization, and economic growth in recent decades. Taiwan was one of the 4 Asian dragons, regions that experienced rapid industrialization and exceptionally high growth rates between the early 1960s and 1990s, but at a high cost to the environment, and thus, it was heavily polluted. Estuaries are highly dynamic and diverse ecosystems that provide multiple ecosystem services that maintain marine ecosystem health and benefit humankind. However, estuaries and the ecosystem services they provide are rapidly degrading due to increasing pressures and changes, especially those in populous, urban areas. Social–environmental analysis integrates scientific information and social activities and thereby provides a comprehensive understanding for the multiparty, joint decision-making processes necessary for successful, sustainable management. In this study, 60 years of economic data and 26 years of water quality data are examined using social–environmental frameworks, the driver-pressure-state-impact-response framework, and the systems approach framework to analyze the management of water quality for an estuary in a populous urban area, the Tamsui River estuary, in Taiwan. Potential societal responses and management measures are identified that can be implemented to reduce human activities, diminish pressure, ameliorate water quality, and enhance the state of the estuarine systems in the Tamsui River and its estuary. The recommended societal responses are increased education, the establishment of community-based river rangers, wetland and mangrove conservation, the development of a circular economy, the implementation of governance measures, and improvements in monitoring and assessments. Improvement of the water quality in the Tamsui River estuary increases the hedonic value of property for people who live near the riverside. Currently, the number of tourists and tourism-based businesses have increased. Nevertheless, improvements in water quality in the Tamsui River estuary bring well-being and benefits that could be further enhanced to increase the cost/benefit relation of the management measures.

The agricultural sector in Syria was heavily affected by the civil war that started in 2011. We investigate the war’s impact on the country’s atmospheric ammonia (NH 3 ) from 2008 to 2019, using measurements from the infrared atmospheric sounding interferometer instrument on board the Metop satellites. We examine the changes in NH 3 close to a fertilizer industry, whose activities were suspended due to conflict-related events. We also explore the effect of war-induced land use/land cover changes on agriculture-emitted ammonia in north-east Syria that has witnessed battles between different groups. The interpretation of the changes in NH 3 is supported by different datasets: visible satellite imagery to assess the effect on industrial activity, reanalysis data from the European center for medium-range weather forecasts to look at the effect of meteorology (temperature, wind speed, and precipitation), and land cover and burned area products from the moderate resolution imaging spectroradiometer (MODIS) to examine land use/land cover changes and fire events during the study period. We show that the NH 3 columns are directly affected by the war. Periods of intense conflict are reflected in lower values over the industry reaching –17%, –47%, and –32% in 2013, 2014, and 2016, respectively, compared to the [2008–2012] average, and a decrease reaching –14% and –15% in the croplands’ area in northeast Syria during 2017 and 2018 (compared to 2011), respectively. Toward the end of the control of Islamic State in Iraq and Syria, an increase in atmospheric NH 3 was accompanied by an increase in croplands’ area that reached up to +35% in 2019 as compared to prewar (2011). This study shows the relevance of remote-sensing data of atmospheric composition in studying societal changes at a local and regional scale.

We report on methane (CH 4 ) stable isotope (δ 13 C and δ 2 H) measurements from landfast sea ice collected near Barrow (Utqiagvik, Alaska) and Cape Evans (Antarctica) over the winter-to-spring transition. These measurements provide novel insights into pathways of CH 4 production and consumption in sea ice. We found substantial differences between the two sites. Sea ice overlying the shallow shelf of Barrow was supersaturated in CH 4 with a clear microbial origin, most likely from methanogenesis in the sediments. We estimated that in situ CH 4 oxidation consumed a substantial fraction of the CH 4 being supplied to the sea ice, partly explaining the large range of isotopic values observed (δ 13 C between –68.5 and –48.5 ‰ and δ 2 H between –246 and –104 ‰). Sea ice at Cape Evans was also supersaturated in CH 4 but with surprisingly high δ 13 C values (between –46.9 and –13.0 ‰), whereas δ 2 H values (between –313 and –113 ‰) were in the range of those observed at Barrow. These are the first measurements of CH 4 isotopic composition in Antarctic sea ice. Our data set suggests a potential combination of a hydrothermal source, in the vicinity of the Mount Erebus, with aerobic CH 4 formation in sea ice, although the metabolic pathway for the latter still needs to be elucidated. Our observations show that sea ice needs to be considered as an active biogeochemical interface, contributing to CH 4 production and consumption, which disputes the standing paradigm that sea ice is an inert barrier passively accumulating CH 4 at the ocean-atmosphere boundary.

Microbial processes, including extracellular enzyme (exoenzyme) production, are a major driver of decomposition and a current topic of interest in Arctic soils due to the effects of climate warming. While enzyme activity levels are often assessed, we lack information on the specific location of these exoenzymes within the soil matrix. Identifying the locations of different soil enzymes is needed to improve our understanding of microbial and overall ecosystem function. Using soil obtained from Utqiaġvik, Alaska, our objectives in the study are (1) to measure the activity of enzymes in soil pore water, (2) to examine the distribution of activity among soil particle size fractions using filtration, and (3) to cross these particle size fraction analyses with disruption techniques (blending to shred and sonication to further separate clumped/aggregated soil materials) to assess how tightly bound the enzymes are to the particles. The results of the soil pore water assays showed little to no enzyme activity (<0.05 nmol g soil –1 h –1 ), suggesting that enzymes are not abundant in soil pore water. In the soil cores, we detected activity for most of the hydrolytic enzymes, and there were clear differences among the particle size and disruption treatments. Higher activities in unfiltered and 50-µm filters relative to much finer 2-µm filters suggested that the enzymes were preferentially associated with larger particles in the soil, likely the organic material that makes up the bulk of these Arctic soils. Furthermore, in the sonication + blending treatment with no filter, 5 of 6 hydrolytic enzymes showed higher activity compared to blending only (and much higher than sonication only), further indicating that enzyme–substrate complexes throughout the organic matter component of the soil matrix are the sites of hydrolytic enzyme activity. These results suggest that the enzymes are likely bound to either the producing microbes, which are bound to the substrates, or directly to the larger organic substrates they are decomposing. This close-proximity binding may potentially minimize the transport of decomposition products away from the microbes that produce them.

Digitization in agriculture is gaining momentum in developing countries. Digital technology aims to improve linkages along the agriculture value chain, thereby enabling farming communities and systems to recover from stresses and to absorb shocks to which farmers are exposed. However, there is the concern that digital technologies have not benefited the agricultural sector in a sustainable way. Stakeholders along the agriculture value chain need significant amounts of information to which they do not have access. In Mali, smartphones and earth observation data are used to support the development of land tenure information services and to improve agriculture statistics. To multiply business opportunities, the scope of the use of these technologies is being expanded to include agronomic advisory next-gen, franchised farm extension services. This article aims to evaluate these initiatives to further understand the way digitization could contribute to sustainable agricultural development and food security. In addition, it aims to determine how effective these technologies are under different conditions and how they can contribute to better sustainable development outcomes. Most evaluation studies of agriculture technology place emphasis on the economic aspects of productivity, profitability, and technical efficiency of the technology and the implications for users’ livelihoods. This study considers technology as a socio-technical phenomenon to understand the underlying processes that may enable or constrain the takeoff and the sustainability of technology. Furthermore, understanding these processes provides valuable theoretical and methodological insights to stakeholders for necessary adjustments of technology to given biophysical, socioeconomic, cultural, and cognitive conditions.

The rapid development of CRISPR-based gene editing has been accompanied by a polarized governance debate about the status of CRISPR-edited crops as genetically modified organisms. This article argues that the polarization around the governance of gene editing partly reflects a failure of public engagement with the current state of research in genomics and postgenomics. CRISPR-based gene-editing technology has become embedded in a narrow narrative about the ease and precision of the technique that presents the gene as a stable object under technological control. By tracing the considerably destabilized scientific understanding of the gene in genomics and postgenomics, this article highlights that this publicly mediated ontology strategically avoids positioning the “ease of CRISPR-based editing” in the wider context of the “complexity of the gene.” While this strategic narrowness of CRISPR narratives aims to create public support for gene-editing technologies, we argue that it stands in the way of socially desirable anticipatory governance and open public dialogue about societal promises and the unintended consequences of gene editing. In addressing the polarization surrounding CRISPR-based editing technology, the article emphasizes the need for engagement with the complex state of postgenomic science that avoids strategic simplifications of the scientific literature in promoting or opposing the commercial use of the gene-editing technology.

A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems meet the criteria for ecologically or biologically significant marine areas, that global emissions driving climate change are directly linked to the demise of sea-ice ecosystems and its ecosystem services, and that the sea-ice ecosystem deserves specific attention in the evaluation of marine protected area planning. The synthesis outlines (1) supporting services, provided in form of habitat, including feeding grounds and nurseries for microbes, meiofauna, fish, birds and mammals (particularly the key species Arctic cod, Boreogadus saida, and Antarctic krill, Euphausia superba, which are tightly linked to the sea-ice ecosystem and transfer carbon from sea-ice primary producers to higher trophic level fish, mammal species and humans); (2) provisioning services through harvesting and medicinal and genetic resources; (3) cultural services through Indigenous and local knowledge systems, cultural identity and spirituality, and via cultural activities, tourism and research; (4) (climate) regulating services through light regulation, the production of biogenic aerosols, halogen oxidation and the release or uptake of greenhouse gases, for example, carbon dioxide. The ongoing changes in the polar regions have strong impacts on sea-ice ecosystems and associated ecosystem services. While the response of sea-ice–associated primary production to environmental change is regionally variable, the effect on ice-associated mammals and birds is predominantly negative, subsequently impacting human harvesting and cultural services in both polar regions. Conservation can help protect some species and functions. However, the key mitigation measure that can slow the transition to a strictly seasonal ice cover in the Arctic Ocean, reduce the overall loss of sea-ice habitats from the ocean, and thus preserve the unique ecosystem services provided by sea ice and their contributions to human well-being is a reduction in carbon emissions.

The Svalbard region faces drastic environmental changes, including sea-ice loss and “Atlantification” of Arctic waters, caused primarily by climate warming. These changes result in shifts in the sea-ice-associated (sympagic) community structure, with consequences for the sympagic food web and carbon cycling. To evaluate the role of sympagic biota as a source, sink, and transmitter of carbon, we sampled pack ice and under-ice water (0–2 m) north of Svalbard in spring 2015 by sea-ice coring and under-ice trawling. We estimated biomass and primary production of ice algae and under-ice phytoplankton as well as biomass, carbon demand, and secondary production of sea-ice meiofauna (>10 µm) and under-ice fauna (>300 µm). Sea-ice meiofauna biomass (0.1–2.8 mg C m –2 ) was dominated by harpacticoid copepods (92%), nauplii (4%), and Ciliophora (3%). Under-ice fauna biomass (3.2–62.7 mg C m –2 ) was dominated by Calanus copepods (54%). Appendicularia contributed 23% through their high abundance at one station. Herbivorous sympagic fauna dominated the carbon demand across the study area, estimated at 2 mg C m –2 day –1 for ice algae and 4 mg C m –2 day –1 for phytoplankton. This demand was covered by the mean primary production of ice algae (11 mg C m –2 day –1 ) and phytoplankton (30 mg C m –2 day –1 ). Hence, potentially 35 mg C m –2 day –1 of algal material could sink from the sympagic realm to deeper layers. The demand of carnivorous under-ice fauna (0.3 mg C m –2 day –1 ) was barely covered by sympagic secondary production (0.3 mg C m –2 day –1 ). Our study emphasizes the importance of under-ice fauna for the carbon flux from sea ice to pelagic and benthic habitats and provides a baseline for future comparisons in the context of climate change.

Biotechnologies in agriculture and food are increasingly governed by both state and nonstate actors. In this article, we explore emerging tensions and contestations in the United States over how gene-editing technologies in agriculture and food should be governed and by whom. This article is framed theoretically by the literatures examining the politics of state and nonstate governance of the agrifood and biotechnology sectors. We draw on semistructured interviews with 45 key actors in the United States, including representatives of regulatory agencies, commodity groups, consumer and environmental nongovernmental organizations (NGOs), biotechnology and food industry, and scientists. In contrast to assumptions that commodity group and industry actors would share a preference for limited or self-regulation, we find growing contestations, with some calling for novel forms of regulatory oversight. Our findings reveal new tensions, fractures, and realignments between and among government, industry, and NGOs actors over gene-editing governance. These tensions and realignments reflect and respond to demands for broader engagement of publics and greater transparency in the governance of biotechnologies in agriculture and food. We argue that these emerging tensions and realignments between and among state and nonstate actors reflect efforts by these actors to incorporate lessons from the genetically modified organism labeling fight as they seek to (re)shape the governance of gene editing in a manner that reflects their interests.
