    Harmful algal blooms: the impacts on cultural ecosystem services and human well-being in a case study setting, Cornwall, UK

    Get PDF
    © 2018 The Authors Whilst harmful algal blooms (HABs) are a natural phenomenon, the impacts of these events can have devastating impacts on human societies. To date, these have largely been studied with reference to economic and health impacts, which can be significant and have impact at both individual and community levels. This paper builds on previous work and addresses recent calls to more fully understand the nuanced human impacts of HABs. Using a framework of cultural ecosystem services, the paper explores how HABs can impact human well-being through disruptions to therapeutic and inspirational opportunities in the natural environment, opportunities for recreation, aesthetic enjoyment, and losses to traditional ways of life, sense of place and collective identity. A snapshot is gleaned into the lived realities of six local residents of St Austell bay, Cornwall, UK, an area frequently affected by HABs via interviews which illustrate how the impacts of HABs can be felt at a much deeper level than are revealed through economic and health analysis. Whilst it is acknowledged the sample size here is limited, the findings nonetheless point to some of the key impacts of HABs in this specific setting and indicate a need for continued research to incorporate local experiences into decisions about how to respond to environmental shocks and what safeguards could help to buffer against the worst of these. It is argued that locally-directed management policies can be developed at scales more appropriate to coastal communities to better respond to their specific needs when considering HAB impacts

    The marine economy of the United Kingdom

    The marine and coastal environment is an important economic asset in the UK, and there is a need for greater information about marine economic activities for the purposes of marine management and policy. However, due to the difficulties of quantifying some marine sectors and separating them from terrestrial activities, the current size and structure of the marine economy is unknown. This paper defines a systematic approach to quantifying the UK marine economy, aiming to capture all activities in the market economy that occur within and depend upon UK marine and coastal environments, and estimates its contribution to the UK economy as a whole. The approach draws on previous research in this area and links sectors used in marine planning with the methodologies used in national accounts. The results suggest that the marine economy contributes double the amount of previous estimates to the UK economy. Changes in the structure of the marine economy, partly due to the expansion of offshore wind energy, may affect its economic contribution. The results also show that marine and coastal leisure and recreation sectors, which were previously thought to have a small economic contribution, are the second largest sector in the UK marine economy and account for the largest number of jobs. By disaggregating the economic sectors, the approach used here can underpin a marine natural capital approach, enabling economic activities to be linked with aspects of marine natural capital

    Future socio-political scenarios for aquatic resources in Europe: An operationalized framework for aquaculture projections

    Climate-driven changes in aquatic environments have already started to affect the European aquaculture sector’s most commercially important finfish and shellfish species. In addition to changes in water quality and temperature that can directly influence fish production by altering health status, growth performance and/or feed conversion, the aquaculture sector also faces an uncertain future in terms of production costs and returns. For example, the availability of key ingredients for fish feeds (proteins, omega-3 fatty acids) will not only depend on future changes in climate, but also on social and political factors, thereby influencing feed costs. The future cost of energy, another main expenditure for fish farms, will also depend on various factors. Finally, marketing options and subsidies will have major impacts on future aquaculture profitability. Based on the framework of four socio-political scenarios developed in the EU H2020 project climate change and European aquatic resources (CERES), we defined how these key factors for the aquaculture sector could change in the future. We then apply these scenarios to make projections of how climate change and societal and economic trends influence the mid-century (2050) profitability of European aquaculture. We used an established benchmarking approach to contrast present-day and future economic performance of “typical farms” in selected European production regions under each of the scenarios termed “World Markets,” “National Enterprise,” “Global Sustainability” and “Local Stewardship.” These scenarios were based partly on the IPCC Special Report on Emissions Scenarios framework and their representative concentration pathways (RCPs) and the widely used shared socio-economic pathways (SSPs). Together, these scenarios contrast local versus international emphasis on decision making, more versus less severe environmental change, and different consequences for producers due to future commodity prices, cash returns, and costs. The mid-century profitability of the typical farms was most sensitive to the future development of feed costs, price trends of returns, and marketing options as opposed to the direct effect of climate-driven changes in the environment. These results can inform adaptation planning by the European aquaculture sector. Moreover, applying consistent scenarios including societal and economic dimensions, facilitates regional to global comparisons of adaptation advice both within and across Blue Growth sectors

    Satellite-assisted monitoring of water quality to support the implementation of the Water Framework Directive

    Get PDF
    The EU Water Framework Directive1 (WFD) is an ambitious legislation framework to achieve good ecological and chemical status for all surface waters and good quantitative and chemical status for groundwater by 2027. A total of 111,062 surface waterbodies are presently reported on under the Directive, 46% of which are actively monitored for ecological status. Of these waterbodies 80% are rivers, 16% are lakes, and 4% are coastal and transitional waters. In the last assessment, 4% (4,442) of waterbodies still had unknown ecological status, while in 23% monitoring did not include in situ water sampling to support ecological status assessment2. For individual (mainly biological) assessment criteria the proportion of waterbodies without observation data is much larger; the full scope of monitoring under the WFD is therefore still far from being realised. At the same time, 60% of surface waters did not achieve ‘good’ status in the second river basin management plan and waterbodies in Europe are considered to be at high risk of having poor water quality based on combined microbial, physical and physicochemical indicators3

    Household consumption, associated fossil fuel demand and carbon dioxide emissions: The case of Greece between 1990 and 2006

    This paper explores how Greece's household consumption has changed between 1990 and 2006 and its environmental implications in terms of fossil fuel demand and carbon dioxide (CO2) emissions. The results show that the 44% increase in Greece's household expenditure between 1990 and 2006 was accompanied by a 67% increase in fossil fuel demand. Of this total, indirect demand accounted for approximately 60% throughout the 16-year period, increasing by 56% overall, whereas direct fossil fuel demand grew by 80%. The results also show that associated CO2 emissions increased by 60%, resulting in a "relative decoupling" from energy demand. This relative decoupling is shown to be due to fossil fuel mix changes from the supply side rather than action from consumers. These insights highlight the opportunities for demand-side policies to further reduce fossil fuel demand and CO2 emissions, allowing Greece to set more proactive and ambitious post-Kyoto targets.Sustainable consumption Demand-side policies Energy demand

    Measuring fossil resource inequality--A case study for the UK between 1968 and 2000

    This paper quantifies fossil resource inequalities amongst income quintiles in the UK between 1968 and 2000. It calculates a resource-based Gini coefficient using an input-output based resource allocation model. The results show that the Gini coefficient for total fossil resource consumption grew by 24% over the time period. By comparison the Gini coefficient for overall household expenditure rose by only 13%. The increase in resource inequality was prompted by the rising demand by high income quintiles for goods and services such as: "fuel and light" (heating and lighting the home), "car use" (private transportation), "recreation", "travel" and "other services". The analysis shows further that the Gini coefficient for "direct" fossil resources ("fuel and light" and "car use") was lower and rose less steeply than the Gini coefficient for fossil resources embodied in other goods and services (indirect fossil resource requirements). Investigation into the drivers behind direct and indirect resource inequalities suggests a number of policy conclusions. Firstly, it is clear that policy initiatives to reduce fossil resource requirements (and the associated climate change impacts) must pay careful attention to distributional differences. Additionally, increased attention needs to be paid to the inequalities associated with indirect fossil resources consumption as well as the more visible direct resource inequalities.Sustainable consumption Fossil resource inequality Income groups Gini coefficient Fossil resource consumption

    Fossil resource trade balances: Emerging trends for the UK

    No full text
    The aim of this paper is to examine the extent to which the UK can be classified as a net importer of fossil resources and a creator of pollution havens abroad between 1968 and 2000. Using input-output techniques and a derived Resource Flow Classification System, both the physical trade balance (PTB) and pollution trade balance (UTB) associated with fossil resource use are computed. The PTB shows that between 1968 and the early 1980's the UK is presented as a net importer of direct fossil resource flows. Between 1984 and 2000, the UK is identified as a net exporter of direct fossil resources. These trends are primarily explained by the UK's discovery and commercial production of North Sea oil and gas fields in the late 1970s. On the other hand, the UTB shows that over the whole period the indirect used flows attributable to the UK's exports are higher than those attributable to its imports. These findings suggest that the UK did not create pollution havens abroad from the use of fossil resources between 1968 and 2000. However, it is noticeable in both cases that from 1995 the UK's position as a net exporter has been decreasing considerably. Maturing North Sea oil and gas fields set against increasing demands for fossil fuels and imported goods is signalling a return to the UK's pre-1984 dependence on direct imported fossil resources and the possible creation of pollution havens abroad. Knowledge of these trends contributes to the evidence base for the UK's changing import and export structure and the potential environmental repercussions at home and abroad.

    Luxury or 'lock-in'? An exploration of unsustainable consumption in the UK: 1968 to 2000

    Sustainable consumption demands the ability to understand the patterns of resource consumption associated with changing lifestyles. This paper explores changes in resource consumption patterns in the UK between 1968 and 2000. Using an environmental input-output model, the paper tracks the fossil resource requirements attributable to 8 high-level functional purposes and finds that overall fossil resource consumption increased 35% over the 32 year period. The four functional purposes most closely related to the provision of basic material needs showed little change over the period. The bulk of the increase in fossil resource requirements was attributable to two specific functional purposes: 1) recreation and entertainment; 2) commuting and business travel. The authors discuss the relevance of these findings for the continuing debate over the question whether rising consumption is being driven by expanding social aspirations (luxury) or whether it is the result of structural lock-in.Sustainable consumption Input-output modelling Human needs Functional purposes Consumer lock-in Social aspirations
