Snare removal resulted in significant declines in snare occupancy (36.9, 95% Bayesian credible interval [4.6, 59.0] reduction in percent area occupied), but snaring levels nonetheless remained high (31.4, [23.6, 40.8] percent area occupied), and came with a substantial financial cost. Our results indicate that snare removal remains an important component of efforts to protect tropical protected areas but by itself is likely insufficient to address this threat.

As countries seek to integrate OECMs into conservation planning, it is useful to consider the types of areas that might meet the formal criteria. To support this goal, I analyzed the different types of measures discussed as possible OECMs in the literature, identifying a wide range of measures, far more diverse than those currently recognized as OECMs. There was a strong emphasis on measures with conservation as a secondary management objective, with most studies being supportive of the potential to balance biodiversity conservation and sustainable resource use. However, many studies have highlighted the need to ensure biodiversity outcomes are achieved and sustained, and that appropriate governance and management structures are in place. Concerns were raised about measures associated with resource extraction, such as fisheries and forestry, which were often considered incompatible with conservation. Very few studies offered a nuanced discussion of specific measures or evaluated whether sites offer conservation outcomes, leaving clear knowledge gaps in translating speculation into evidence. Nevertheless, the current literature offers a strong starting point from which to target potential case studies to build the evidence base necessary to advance OECMs.</p>","PeriodicalId":157,"journal":{"name":"Conservation Letters","volume":"17 4","pages":""},"PeriodicalIF":7.7,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/conl.13027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141177600","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}

While transparent biodiversity disclosures could help shift business operations away from activities that harm biodiversity, the weak target wording implies voluntary and unstandardized disclosures, which tend to be low quality and ineffective. Moreover, examination of scientific and practical insights strongly indicates that the evolving strategy of disclosures led by businesses may prioritize short-term business and investment interests while neglecting biodiversity outcomes and the wider systemic risks they pose. We argue that there is a risk of limited if not altogether perverse outcomes from the target, where businesses provide ambiguous disclosures that fail to reduce impacts on biodiversity, yet an increase in volume and frequency of disclosures suggests progress toward the target.

El Bizri,&nbsp;Mahesh Poudyal,&nbsp;Edward Mundy","doi":"10.1111/conl.13023","DOIUrl":"10.1111/conl.13023","url":null,"abstract":"&lt;p&gt;Wildlife use is widespread across the world where animals and their derivates are consumed and/or traded (Ingram et al., &lt;span&gt;2021&lt;/span&gt;). When the use is unsustainable, it is a leading cause of biodiversity loss worldwide, with profound consequences for ecosystem services and functions (IPBES, &lt;span&gt;2022&lt;/span&gt;). In December 2022, Parties to the Convention on Biological Diversity adopted the Kunming–Montreal Global Biodiversity Framework, agreeing to achieve the sustainable use and management of biodiversity as one of four central goals by 2050. Furthermore, the COVID-19 pandemic has focussed global attention on the wildlife trade and potential risk of zoonotic emerging infectious disease spread. From February 2023, the World Health Organization (WHO) has been negotiating drafts of a global Pandemic Agreement, calling for collective action on pandemic prevention, preparedness, and response, including the need to “take measures to reduce risks of zoonotic spill-over” (Article 4; World Health Organisation, &lt;span&gt;2024&lt;/span&gt;). Given how wholly interconnected these issues are, leveraging approaches that tackle integrated issues around the health of people, animals, and ecosystems, such as One Health and Planetary Health approaches (de Castañeda et al., &lt;span&gt;2023&lt;/span&gt;), will be paramount to addressing the global challenges of biodiversity loss and zoonotic disease emergence.&lt;/p&gt;&lt;p&gt;Managing the use of wildlife can be challenging for many reasons, including the number of actors involved along varied supply chains across rural and urban areas, the complexities around the legality of trade in different circumstances, and the capacities of governments to act (Ingram et al., &lt;span&gt;2021&lt;/span&gt;). The COVID-19 pandemic prompted a worldwide initiative to end the wildlife trade (Coalition to End the Trade, &lt;span&gt;2020&lt;/span&gt;), resulting in certain countries banning physical wildlife markets. Yet, it is becoming increasingly evident that digital services platforms, particularly social media platforms, are playing a pivotal role in the legal and illegal trade of wildlife (Morcatty et al., &lt;span&gt;2021&lt;/span&gt;). Yet, little has been done to stem the illegal online trade of wildlife, which undermines efforts to manage the trade effectively, sustainably, and safely (Morcatty et al., &lt;span&gt;2021&lt;/span&gt;). Here, we highlight two major ways in which technology companies running global social media, e-commerce (marketplaces), and content-sharing platforms (hereafter just “tech companies”) can assist in achieving the goals of the Kunming–Montreal Global Biodiversity Framework and the WHO Pandemic Agreement.&lt;/p&gt;&lt;p&gt;For the latter, examples could include public lists of tech companies, which are not part of groups working to reduce online illegal wildlife trade (Sebagh, &lt;span&gt;2021&lt;/span&gt;), and transparent monitoring of such groups to ensure that activities are taking place and reporting tools are effective.

We used <i>The MPA Guide</i> framework to assess the the world's largest 100 MPAs by area, representing nearly 90% of reported global MPA coverage and 7.3% of the global ocean area, and analyzed the distribution of MPA quality across political and ecological regions. A quarter of the assessed MPA coverage is not implemented, and one-third is incompatible with the conservation of nature. Two factors contribute to this outcome: (1) many reported MPAs lack regulations or management, and (2) some MPAs allow high-impact activities. Fully and highly protected MPAs account for one-third of the assessed area but are unevenly distributed across ecoregions in part because some nations have designated large, highly protected MPAs in their overseas or remote territories.

As a result, environmental professionals who experience this risk in the workplace are unlikely to be equipped with the knowledge, skills, or context to support themselves, colleagues, or peers, in experiences of ecological grief. In this paper, we provide information, guidance, and examples of workplace support for ecological grief. Drawing on insights from the field of grief and bereavement, we identify peer support and organizational responses as key supportive factors for those experiencing ecological grief. We also present a new concept, ‘‘ecological grief literacy,’’ to guide effective peer and organizational support.
