Using local ecological knowledge to assess the status of the Critically Endangered Chinese giant salamander Andrias davidianus in Guizhou Province, China

The Critically Endangered Chinese giant salamander Andrias davidianus, the world's largest amphibian, is severely threatened by unsustainable exploitation of wild individuals. However, field data with which to assess the salamander's status, population trends, or exploitation across its geographical range are limited, and recent field surveys using standard ecological field techniques have typically failed to detect wild individuals. We conducted community-based fieldwork in three national nature reserves (Fanjingshan, Leigongshan and Mayanghe) in Guizhou Province, China, to assess whether local ecological knowledge constitutes a useful tool for salamander conservation. We collected a sample of dated salamander sighting records and associated data from these reserves for comparative assessment of the relative status of salamander populations across the region. Although Fanjingshan and Leigongshan are still priority sites for salamander conservation, few recent sightings were recorded in either reserve, and respondents considered that salamanders had declined locally at both reserves. The species may already be functionally extinct at Mayanghe. Although respondent data on threats to salamanders in Guizhou are more difficult to interpret, overharvesting was the most commonly suggested explanation for salamander declines, and it is likely that the growing salamander farming industry is the primary driver of salamander extraction from Guizhou's reserves. Questionnaire-based surveys can collect novel quantitative data that provide unique insights into the local status of salamander populations, and we advocate wide-scale incorporation of this research approach into future salamander field programmes

Understanding the role of value in coral reef science

This thesis explores the role of value in coral science from the perspective of philosophy of science in practice. More specifically, it looks at the epistemology of different practices and theories in coral science, particularly how they interact with various forms of value, and how these forms of value can be understood. The arguments are organised into five chapters, which all make use of data collected in interviews with coral scientists, as well as ideas from coral science literature. The first presents an examination of ecological baselines, which I show do not simply ‘shift’ as has been supposed, but vary for a variety of reasons. This raises a question I address in the second chapter: when is this variation considered legitimate? The answer depends on the value of different reef states being considered. After showing how coral scientists navigate this in practice, I move on to the next two chapters where I explore areas of coral science where important forms of valuation take place: first, the value frameworks of intrinsic value and ecosystem services; and second, the use of bioacoustic techniques to assess reef health from non-human perspectives. These offer examples of how different forms of value shape coral science and make it relevant to the lifeforms practising and influenced by it. In the final chapter I present a view of coral science as a form of multispecies niche construction, both in the lab and the field. On this view, coral science is aimed at the flourishing of a range of living systems. This offers a better understanding of science-value interactions in socio-ecological contexts, such as when faced with decisions about baselines and interventions designed around these. Understanding how to navigate such situations is likely to become increasingly important as the challenges of surviving as a species continue to mount.Economic and Social Research Council (ESRC

GHG Accounting for Low-emissions Branded Steel and Aluminum Products

Iron, steel, and aluminum products are major sources of GHG emissions, and these emissions have traditionally been hard to abate. As of 2020, the iron and steel and the aluminum industries accounted for 7% and 3% of global GHG emissions respectively. In recent years, demand has increased substantially for “green” iron, steel, and aluminum products which can allow purchasing companies to reduce their reported upstream scope 3 GHG emissions. In response to increased demand, companies in these industries have made an expanding array of green products available to customers. “GHG Accounting for Low-emissions Branded Steel and Aluminum Products,” draws from an original analysis of over a dozen steel and aluminum low carbon brands and argues that while green-branded products can play a role in incentivizing and supporting the expansion of green procurement, they exist in a market that lacks the transparent, harmonized system for emissions accounting necessary to drive broad-based emissions reductions in the materials sector. This paper provides concrete steps to achieving a transparent and cohesive green market for low-emissions branded steel and aluminum products

AVOIDING COLLAPSE: RESILIENCE AND SUSTAINABLE DEVELOPMENT IN VULNERABLE SMALL ISLANDS

Small islands dependent on reef fisheries, farming and tourism are vulnerable to rising human and natural pressures and may target "sustainable" development. Marine Protected Areas (MPA) have a proven ability to meet ecological goals, such as restoring fisheries and preserving ecosystem function across scales. However, there is a comparative lack of scientific baseline data and social research which may help local MPA to overcome failures in achieving mixed conservation and development goals in populated coastal areas facing intense pressure. This fieldwork-based case study researched in French and Creole languages in the sub-tropical, mid-Oceanic island of Rodrigues (Mauritius, Indian Ocean) addresses two main questions: "Are conservation and development compatible goals for MPA in small islands reliant on fisheries and tourism?", and, "Do social-ecological resilience concepts help clarify related issues of sustainability?". Results from two quantitative surveys with fishers {n=93) and tourists (n=351) on one level support a "win-win" scenario for conservation and development. Local fishers' knowledge suggested marine fish species including large predators of ecological and economic significance had been in decline for decades. Tourists' stated willingness to pay to use Marine and Coastal Protected Areas could help fund consen/ation of biodiversity and fishery enhancement, with fee options ranging from MPA up to island-level. Beyond this, downside risks emerged from qualitative interviews with key informants (n=70) and historical analysis of island-level social-ecological resilience testing the explanatory value of the conceptual Adaptive Cycle model (Holling and Gunderson 2002). A recent crisis catalysed by severe drought (1970s) led to deep social and ecological changes (collapse in farming, migration and external dependence), while subsequent policies failed to address key drivers, instead creating negative feedbacks ensuring degradation extended outward from the coast. Remote and vulnerable small islands with few resources (forests, soil, water, energy) need significant capital inputs from higher scales which are seldom taken into account in determining the balance of winners and losers in conservation and development policy at MPA or island level. A lack of interisland trust (social capital), water scarcity, climate change and migration arise as critical issues for the future. Rodrigues characterises the secondary importance of island regions within larger Island states, and underlines the cross-scale and cross-temporal nature of sustainability in resilience terms. This thesis' main contribution lies in its first demonstration of shifting baselines in an island reef fishery or MPA context. Findings contributed to the establishment of MPA In the fieldwork site of Rodrigues, and are of broad relevance for MPA policy across the tropics and beyond. More studies are needed across other ecosystems and cultures

A Social Scientist's Perspective on the Potential Benefits of the Census of Marine Life

Over 300 natural scientists in 53 nations are taking part in the Census of Marine Life (CoML) to investigate what lived, what lives, and what will live in the oceans. The CoML is a scientific experiment that is exploring the limits of ocean science. The paper discusses the potential applications of CoML research and the mechanisms by which the potential benefits can be measured and preserved. I recommend developing and integrating policy advisory committees with the natural science activities to both maximize the benefits of the research and to avoid unintended consequences.biodiversity; marine policy

Cumulative human impacts on coral reefs: assessing risk and management implications for Brazilian coral reefs

Effective management of coral reefs requires strategies tailored to cope with cumulative disturbances from human activities. In Brazil, where coral reefs are a priority for conservation, intensifying threats from local and global stressors are of paramount concern to management agencies. Using a cumulative impact assessment approach, our goal was to inform management actions for coral reefs in Brazil by assessing their exposure to multiple stressors (fishing, land-based activities, coastal development, mining, aquaculture, shipping, and global warming). We calculated an index of the risk to cumulative impacts: (i) assuming uniform sensitivity of coral reefs to stressors; and (ii) using impact weights to reflect varying tolerance levels of coral reefs to each stressor. We also predicted the index in both the presence and absence of global warming. We found that 16% and 37% of coral reefs had high to very high risk of cumulative impacts, without and with information on sensitivity respectively, and 42% of reefs had low risk to cumulative impacts from both local and global stressors. Our outputs are the first comprehensive spatial dataset of cumulative impact on coral reefs in Brazil, and show that areas requiring attention mostly corresponded to those closer to population centres. We demonstrate how the relationships between risks from local and global stressors can be used to derive strategic management actions

Once and Future Gulf of Mexico Ecosystem: Restoration Recommendations of an Expert Working Group

The Deepwater Horizon (DWH) well blowout released more petroleum hydrocarbons into the marine environment than any previous U.S. oil spill (4.9 million barrels), fouling marine life, damaging deep sea and shoreline habitats and causing closures of economically valuable fisheries in the Gulf of Mexico. A suite of pollutants—liquid and gaseous petroleum compounds plus chemical dispersants—poured into ecosystems that had already been stressed by overfishing, development and global climate change. Beyond the direct effects that were captured in dramatic photographs of oiled birds in the media, it is likely that there are subtle, delayed, indirect and potentially synergistic impacts of these widely dispersed, highly bioavailable and toxic hydrocarbons and chemical dispersants on marine life from pelicans to salt marsh grasses and to deep-sea animals. As tragic as the DWH blowout was, it has stimulated public interest in protecting this economically, socially and environmentally critical region. The 2010 Mabus Report, commissioned by President Barack Obama and written by the secretary of the Navy, provides a blueprint for restoring the Gulf that is bold, visionary and strategic. It is clear that we need not only to repair the damage left behind by the oil but also to go well beyond that to restore the anthropogenically stressed and declining Gulf ecosystems to prosperity-sustaining levels of historic productivity. For this report, we assembled a team of leading scientists with expertise in coastal and marine ecosystems and with experience in their restoration to identify strategies and specific actions that will revitalize and sustain the Gulf coastal economy. Because the DWH spill intervened in ecosystems that are intimately interconnected and already under stress, and will remain stressed from global climate change, we argue that restoration of the Gulf must go beyond the traditional "in-place, in-kind" restoration approach that targets specific damaged habitats or species. A sustainable restoration of the Gulf of Mexico after DWH must: 1. Recognize that ecosystem resilience has been compromised by multiple human interventions predating the DWH spill; 2. Acknowledge that significant future environmental change is inevitable and must be factored into restoration plans and actions for them to be durable; 3. Treat the Gulf as a complex and interconnected network of ecosystems from shoreline to deep sea; and 4. Recognize that human and ecosystem productivity in the Gulf are interdependent, and that human needs from and effects on the Gulf must be integral to restoration planning. With these principles in mind, the authors provide the scientific basis for a sustainable restoration program along three themes: 1. Assess and repair damage from DWH and other stresses on the Gulf; 2. Protect existing habitats and populations; and 3. Integrate sustainable human use with ecological processes in the Gulf of Mexico. Under these themes, 15 historically informed, adaptive, ecosystem-based restoration actions are presented to recover Gulf resources and rebuild the resilience of its ecosystem. The vision that guides our recommendations fundamentally imbeds the restoration actions within the context of the changing environment so as to achieve resilience of resources, human communities and the economy into the indefinite future
