A cascade model and initial exploration of co-production processes underpinning the ecosystem services of geothermal areas

This paper presents the first study in the academic literature to explore the various stages in the formation of geothermal ES and their interactions between the biosphere and anthroposphere. This is achieved through the development of the first ES cascade model in the academic literature specific to geothermal ES, which integrates the four main stages of co-production: value attribution, mobilisation of ES potential, value appropriation, and commercialisation. In so doing, conceptual understanding of human-environment relationships and processes in the context of geothermal ES are deepened. Examples from the academic and grey literature demonstrate that realisation of the full spectrum of benefits from geothermal areas often demands the mobilisation of various forms of physical capital. Reaping the benefits of provisioning ES, such as heat and minerals, or formal recreational experiences, such as geothermal spas, necessitates human interventions. Opportunities of likely value have to be attributed, with resources being mobilised in order to plan and research prospectivity, then benefits appropriated with a view to their commercialisation. Large-scale, industrial projects, especially geothermal power plants in high enthalpy fields, also constitute an overlap between anthropogenic and ecological systems, often leading to ES trade-offs, especially due to visual and noise impacts on the surroundings. Depending on the sociocultural context, multiple and conflicting value domains may be impacted by such ventures, justifying the adoption of a pluralist approach to valuation and use of integrated decision-support platforms to aid decision-makers.

Reflections on the ecosystem services of whales and valuing their contribution to human well-being

Although whale ecosystem services have been scarcely explored in the academic literature, they illustrate many of the threats, trade-offs and decision-making dilemmas common to marine ecosystem services in general – climate change impacts, the ongoing need to provide remote communities with forms of sustenance, and the potential development of new economic sectors which are prosperous but undermine traditional ways of life. In this paper, the first evaluation is carried out of the ecosystem services specific to whales, involving (a) their classification using the established Common International Classification Ecosystem Services (CICES) framework, (b) an assessment of the most suitable methods for their valuation, and (c) implications for decision-making. Our findings are that whale ecosystem services belong to all three categories of the CICES classification and cultural services are the most common type. The most suitable approach for the respective valuation of each service depends on the local socio-cultural context, a fundamental ingredient in value formation, which can formulate on either an individual or collective basis. In the case of individual value formation, this paper recommends the use of economic information derived from non-market valuation techniques; for collective, non-monetary techniques are advised. Given the complexity of human-environment interactions, a pluralist approach to valuation is likely to be required, whereby decision-makers are informed about impacts to whale ecosystem services through a mixture of economic and non-monetary information. A logical consequence of value pluralism is the need for decision-support platforms which can satisfactorily integrate different types of information concerning ecosystem service impacts, evaluating these against multiple marine management objectives. The paper briefly reflects on the potential of Multi-Criteria Decision Analysis to fulfil this ambition, before discussing some of the current challenges and barriers which have limited the uptake of ecosystem services research in marine planning and decision-making.

Whale sanctuaries–An analysis of their contribution to marine ecosystem-based management

Goal 14, ‘Life Below Water’, of the United Nations Sustainable Development Goals sets a target for nations to increase the number of marine protected areas managed using ecosystem-based management, which requires interventions focused on fish stock conservation and enhancement, environmental sustainability and ecosystem services of benefit to human beings. Although not adhering to the International Union for Conservation of Nature’s criteria for marine protected areas, whale sanctuaries are an increasingly common approach to conservation around the world. This paper is the first in the academic literature to use a case study approach to review the extent to which whale sanctuaries contribute to ecosystem-based management. A fifteen-criteria framework for marine ecosystem-based management is applied with reference to six whale sanctuary case studies, including the International Whaling Commission’s two designations in the Indian Ocean and Southern Ocean. The review underscores the generally very limited contribution of whale sanctuaries to ecosystem-based management, unless they are explicit in stating conservation goals and embedding these within iterative management plans. The Hawaiian Islands Humpback Whale National Marine Sanctuary is cited as an example of an approach that comes closest to fulfilling the objectives of ecosystem-based management, albeit its designation lacks consideration of ecosystem dynamics and the interrelationships between multiple economic actors operating within its boundaries. In order to meet the requirements of Goal 14, the case studies in this paper reveal advancements necessary for whale sanctuaries to transition towards ecosystem-based management: establishment of objectives broader than the conservation of whale stocks, assessment of the contribution of the sanctuary to human well-being and trade-offs in ecosystem services, accounting for ecological and socio-economic dynamics, and ensuring broad stakeholder consultation and participatory adaptive management.

“Small Science”: Community Engagement and Local Research in an Era of Big Science Agendas

Community engagement in the research process is more than communication and outreach. It is a process of co-production of knowledge. The co-production of knowledge starts and ends at the “small” local level but is embedded in “big” processes that are nested in academic and research institution priorities. This chapter problematizes the issues of small-to-big science and reflects on limitations related to community engagement in research such as community research fatigue, un-standardized research ethics protocols across research institutions, and limitations in funding bodies’ budget schemes. It considers lessons learned by theorizing a “sliding scale of community engagement” that can be used to conceptualize the definitions of community engagement activities within a large research project. The chapter also places emphasis on discussion of the community-engagement experiences of the Nordforsk-funded Nordic Centre of Excellence project Arctic Climate Predictions: Pathways to Resilient, Sustainable Societies (ARCPATH). This project has facilitated excellent collaboration with our informants in our research communities and hence provides a significant example of the co-production of knowledge that we seek to encourage.

The Essentials of Marine Biotechnology

Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well as tried to support new economic endeavors (ocean energy, desalination for water supply, and seabed mining). Modern societies and lifestyle resulted in an increased demand for dietary diversity, better health and well-being, new biomedicines, natural cosmeceuticals, environmental conservation, and sustainable energy sources. These societal needs stimulated the interest of researchers on the diverse and underexplored marine environments as promising and sustainable sources of biomolecules and biomass, and they are addressed by the emerging field of marine (blue) biotechnology. Blue biotechnology provides opportunities for a wide range of initiatives of commercial interest for the pharmaceutical, biomedical, cosmetic, nutraceutical, food, feed, agricultural, and related industries. This article synthesizes the essence, opportunities, responsibilities, and challenges encountered in marine biotechnology and outlines the attainment and valorization of directly derived or bio-inspired products from marine organisms. First, the concept of bioeconomy is introduced. Then, the diversity of marine bioresources including an overview of the most prominent marine organisms and their potential for biotechnological uses are described. This is followed by introducing methodologies for exploration of these resources and the main use case scenarios in energy, food and feed, agronomy, bioremediation and climate change, cosmeceuticals, bio-inspired materials, healthcare, and well-being sectors. The key aspects in the fields of legislation and funding are provided, with the emphasis on the importance of communication and stakeholder engagement at all levels of biotechnology development. Finally, vital overarching concepts, such as the quadruple helix and Responsible Research and Innovation principle are highlighted as important to follow within the marine biotechnology field. The authors of this review are collaborating under the European Commission-funded Cooperation in Science and Technology (COST) Action Ocean4Biotech – European transdisciplinary networking platform for marine biotechnology and focus the study on the European state of affairs.

Ageing gracefully? Semi-dry storage as a maturation process to develop the sensory characteristics of the edible red seaweed dulse (Palmaria palmata).

The potential of seaweeds as food is gaining increasing interest among Western consumers. This trend is supported by the nutritional benefits of several species such as Palmaria palmata. Product flavor is a major factor governing consumer acceptance. Developing more attractive flavors in edible seaweeds is a key to sustain the current health food movement based on this resource in Europe. Semi-dry (SD) storage of P. palmata was investigated as a mean to increase its sensory quality. SD-samples containing 20% moisture and dried (D) samples (6% moisture) stored up to 126 days were studied. SD-samples stored for a long period (61 and 126 days) developed a distinct sweet, rich, complex flavor and odor as well as a softer texture compared to SD-samples stored for a shorter period (12 days) and D-samples stored for 126 days. Variations in nutritional compounds and physico-chemical properties among samples along with increasing levels and diversity of volatile compounds in SD-samples during storage compared to D-126 suggest that a variety of flavor compounds arise from biochemical reactions involving lipids, proteins and carbohydrates. These reactions are either endogenous or the result of the activity of microorganisms naturally present in the seaweed. They are promoted by a higher moisture content than in dried material (20% vs 6%) and long storage times. These results provide a basis which can be applied to control the storage conditions of seaweeds to produce flavor-rich ingredients attractive to Western consumers.

Data on the sensory characteristics and chemical composition of the edible red seaweed dulse (Palmaria palmata) after dry and semi-dry storage.

The data article refers to the paper “Semi-dry storage as a maturation process for improving the sensory characteristics of the edible red seaweed dulse (Palmaria palmata)”. The data refers to the analysis of samples of the edible seaweed species Palmaria palmata during storage in a dry (D, containing ca. 6 % moisture) and semi-dry state (SD, containing ca. 20 % moisture). The article includes data from the analysis of samples taken at 0, 12, 61 and 126 days of storage to evaluate the effect of moisture content and storage time on the sensory characteristics of the product. The variations in flavor, odor and texture between samples were measured by sensory evaluation. Data from the analysis of flavor-active compounds (free amino acids and volatile compounds), macronutrient content (soluble proteins and carbohydrates, lipid and mineral fractions), physico-chemical properties (water activity, water and oil-binding capacities, swelling capacity), color and microbial load are also reported. The information provided in this article can be used by industrial stakeholders (seaweed producers, food industry) to optimize processing and storage conditions of edible seaweeds and by scientists to build upon further knowledge to improve the quality of seaweeds in food applications.
