The Future of the Oceans Past: Towards a Global Marine Historical Research Initiative
Historical research is playing an increasingly important role in marine sciences. Historical data are also used in policy making and marine resource management, and have helped to address the issue of shifting baselines for numerous species and ecosystems. Although many important research questions still remain unanswered, tremendous developments in conceptual and methodological approaches are expected to contribute to a comprehensive understanding of the global history of human interactions with life in the seas. Based on our experiences and knowledge from the \"History of Marine Animal Populations\" project, this paper identifies the emerging research topics for future historical marine research. It elaborates on concepts and tools which are expected to play a major role in answering these questions, and identifies geographical regions which deserve future attention from marine environmental historians and historical ecologists.
Humanities for the Environment 2018 Report—Ways to Here, Ways Forward
We introduce the Humanities for the Environment (HfE) 2018 Report. The HfE 2018 Report consists of two publications; of which this Special Issue is one. The other is a special section of the journal Global and Planetary Change 156 (2017); 112–175. While the Humanities special issue may primarily reach our colleagues in the humanities disciplines; the Global and Planetary Change section reaches out to that journal’s primary readership of earth scientists. The HfE 2018 Report provides examples of how humanities research reveals and influences human capacity to perceive and cope with environmental change. We hope that the HFE 2018 Report will help change perceptions of what it is we do as humanities scholars.
Historical marine footprint for Atlantic Europe, 1500–2019
Over the last 500 years, Europe (excluding Russia) consumed over 2500 million tonnes of ocean biomass. This is based on detailed historical data that we provide for human consumption per capita which was stable from 1500 to 1899 and tripled in the twentieth century. In the last 300 years, cod and herring dominated human seafood consumption. Whaling for non-food uses peaked in the 1830s and declined as cetaceans became scarce. Seafood consumption increased rapidly after 1900, and by the late 1930s, annual marine consumption in Atlantic Europe reached 7 million tonnes of biomass, facilitated by the globalisation of whaling. Atlantic European consumption, including fishmeal for animal feed, peaked at more than 12 million tonnes annually in the 1970s, but declined thereafter. The marine footprint of Atlantic Europe was significant well before modern fisheries statistics commenced. Our findings can inform future assessments of ocean health and marine life’s importance for human society.
Intake of Dairy Products in Relation to Periodontitis in Older Danish Adults
This cross-sectional study investigates whether calcium intakes from dairy and non-dairy sources, and absolute intakes of various dairy products, are associated with periodontitis. The calcium intake (mg/day) of 135 older Danish adults was estimated by a diet history interview and divided into dairy and non-dairy calcium. Dairy food intake (g/day) was classified into four groups: milk, cheese, fermented foods and other foods. Periodontitis was defined as the number of teeth with attachment loss ≥3 mm. Intakes of total dairy calcium (Incidence-rate ratio (IRR) = 0.97; p = 0.021), calcium from milk (IRR = 0.97; p = 0.025) and fermented foods (IRR = 0.96; p = 0.03) were inversely and significantly associated with periodontitis after adjustment for age, gender, education, sucrose intake, alcohol consumption, smoking, physical activity, vitamin D intake, heart disease, visits to the dentist, use of dental floss and bleeding on probing, but non-dairy calcium, calcium from cheese and other types of dairy food intakes were not. Total dairy foods (IRR = 0.96; p = 0.003), milk (IRR = 0.96; p = 0.028) and fermented foods intakes (IRR = 0.97; p = 0.029) were associated with reduced risk of periodontitis, but cheese and other dairy foods intakes were not. These results suggest that dairy calcium, particularly from milk and fermented products, may protect against periodontitis. Prospective studies are required to confirm these findings.
Inventing the Grand Banks: A deep chart
As a feature of the Fish Revolution (1400–1700), the early modern “invention” of the Grand Banks in literary and cartographical documents facilitated a massive and unprecedented extraction of cod from the waters of the north Atlantic and created the Cod/Sack trade Triangle. This overlapped with the southern Atlantic Slave, Sugar, and Tobacco Triangle to capitalise modern European and North American societies. In 1719, Pierre de Charlevoix claimed that the Grand Banks was “properly a mountain, hid under water,” and noted its cod population “seems to equal that of the grains of sand which cover this bank.” However, two centuries later in 1992, in the face of the collapse of the fishery, and fearing its extinction, a moratorium was placed on five centuries of harvesting Grand Banks cod. The invention and mining of its waters serves as a bellwether for the massive resource extractions of modernity that drive the current leviathan and “wicked problem” of global warming. The digital environmental humanities narrative of this study is parsed together from 83 pieces of Grand Banks charting from 1504 to 1833, which are juxtaposed through Humanities GIS applications with English and French cod‐catch records kept between 1675 and 1831, letters regarding Cabot's 1497 voyage, Shakespeare's The Tempest (1611) and scientific essays by De Brahms (1772) and Franklin (1786). The early modern “invention” of the Grand Banks in literary and cartographical documents contributed to facilitating a massive and unprecedent extraction of cod from the waters of the north Atlantic and created the Cod/Sack trade Triangle. This feature of the Fish Revolution (1400–1700) over lapped with the southern Atlantic Slave, Sugar and Tobacco Triangle in its contribution to the capitalization of modern European and North America societies. In 1719, Pierre de Charlevoix claimed that the Grand Banks was “properly a mountain, hid under water,” and noted its cod population “seems to equal that of the grains of sand which cover this bank.” However, two centuries later in 1992, in the face of the collapse of the fishery, and fearing its extinction, a moratorium was placed on five centuries of harvesting cod from north‐west Atlantic waters. This study examines 83 Grand Banks charts drafted between 1504 to 1833, and digitally contextualizes the morphology of their fishery symbolism over three hundred years with English and French cod‐catch records (1675–1831), epistolary accounts of John Cabot’s accidental discovery of a massive shoal of Gadus morhua (cod) during his 1497 voyage to a “newfoundland”; the influence of the emerging Grand Banks fishery on William Shakespeare’s The Tempest (1611) and scientific essays on the oceanic system of the Gulf Stream by William Gerard De Brahm (1772) and Benjamin Franklin (1786). This study illustrates through methods in digital hermeneutics and humanities GIS how an unprecedent extraction of cod from north‐west Atlantic waters influenced early modern cartographical, literary, and scientific perceptions, discourses and practices, situating the Grand Banks as an invention of the Fish Revolution resulting from the confluence of European and North American maritime culture that shaped the course of modern transatlantic political‐economic development and relations.e00085
Effective strategies that enhance the social impact of social sciences and humanities research
Background We are witnessing increasing demand from governments and society for all sciences to have relevant social impact and to show the returns they provide to society. Aims and objectives This paper reports strategies that promote social impact by Social Sciences and Humanities (SSH) research projects. Methods An in-depth analysis of six Social Sciences and Humanities research projects that achieved social impact was carried out to identify those strategies. For each case study, project documents were analysed and qualitative fieldwork was conducted with diverse agents, including researchers, stakeholders and end-users, with a communicative orientation. Findings The strategies that were identified as contributing to achieving social impact include a clear focus of the project on social impact and the definition of an active strategy for achieving it; a meaningful involvement of stakeholders and end-users throughout the project lifespan, including local organisations, underprivileged end-users, and policy makers who not only are recipients of knowledge generated by the research projects but participate in the co-creation of knowledge; coordination between projects’ and stakeholders’ activities; and dissemination activities that show useful evidence and are oriented toward creating space for public deliberation with a diverse public. Discussion and conclusions The strategies identified can enhance the social impact of Social Sciences and Humanities research. Furthermore, gathering related data, such as collaboration with stakeholders, use of projects’ findings and the effects of their implementation, could allow researchers to track the social impact of the projects and enhance the evaluation of research impact.
World War II and the \Great Acceleration\ of North Atlantic Fisheries
World War II impacted both the marine and the terrestrial environment of the North Atlantic, triggered major political and economic decisions with profound cultural implications, and eventually induced a change in ocean management. The War helped develop technologies and state responses to immediate post-war market problems and impacted the Great Acceleration of fisheries between 1945 and 1975. During the war, fisheries were closed completely only in certain parts of the most fished waters, such as the central North Sea and the English Channel. Even in the most affected Northern European waters some fishing continued throughout the war. Fishing was carried on in the waters off Iceland and the Arctic, but extractions were much reduced. Previously unfished stocks in the Baltic were targeted for the first time ever. The effect of the closure of certain fisheries was an overall increase of survival rates of marine animals. Technological advances made during the War increased the fishing efficiency of vessels when the technology was put to commercial use soon after the War. The immediate benefit of better catch-per-unit effort after the War was concealed by the slump in the international fish market. The wartime 'dividend' of marine resources was largely spent by the mid-1950s in the North Sea and by 1960 in the wider North Atlantic. The war disrupted market allegiances, effectively ended old fishing patterns and introduced a forced modernisation in the High North. Among North Sea countries, Denmark in particular responded to the disruption of the market for fresh fish by introducing reduction fishery, which led to severe environmental stress and eventually a collapse of the North Sea herring stock. Before WWII, the oceans had largely been regulated according to the international law of open access to all ocean resources. North Sea countries resumed negotiations over fishing rights after 1945, expecting to revert to old principles. However, U.S. President Harry Truman's declaration against Japan came to impact fishing negotiations in the North Atlantic and changed post-war fishing management forever.
The North Atlantic Fish Revolution (ca. AD 1500)
We propose the concept of the “Fish Revolution” to demarcate the dramatic increase in North Atlantic fisheries after AD 1500, which led to a 15-fold increase of cod (Gadus morhua) catch volumes and likely a tripling of fish protein to the European market. We consider three key questions: (1) What were the environmental parameters of the Fish Revolution? (2) What were the globalising effects of the Fish Revolution? (3) What were the consequences of the Fish Revolution for fishing communities? While these questions would have been considered unknowable a decade or two ago, methodological developments in marine environmental history and historical ecology have moved information about both supply and demand into the realm of the discernible. Although much research remains to be done, we conclude that this was a major event in the history of resource extraction from the sea, mediated by forces of climate change and globalisation, and is likely to provide a fruitful agenda for future multidisciplinary research.
Humanities for the Environment—A Manifesto for Research and Action
Human preferences, practices and actions are the main drivers of global environmental change in the 21st century. It is crucial, therefore, to promote pro-environmental behavior. In order to accomplish this, we need to move beyond rational choice and behavioral decision theories, which do not capture the full range of commitments, assumptions, imaginaries, and belief systems that drive those preferences and actions. Humanities disciplines, such as philosophy, history, religious studies, gender studies, language and literary studies, psychology, and pedagogics do offer deep insights into human motivations, values, and choices. We believe that the expertise of such fields for transforming human preferences, practices and actions is ignored at society’s peril. We propose an agenda that focuses global humanities research on stepping up to the challenges of planetary environmental change. We have established Environmental Humanities Observatories through which to observe, explore and enact the crucial ways humanistic disciplines may help us understand and engage with global ecological problems by providing insight into human action, perceptions, and motivation. We present this Manifesto as an invitation for others to join the “Humanities for the Environment” open global consortium of humanities observatories as we continue to develop a shared research agenda.
