    Fishing is one of the most dangerous professions in the world. India with one million active fishermen population still lacks a reliable boat-to-shore communication network. Fishermen with smaller boat are more vulnerable to the wilder nature of the ocean, due to dynamic sea current, wind speed, direction and wave heights, etc. They form 80% of the entire fishing community. There being no physical boundary, the risk of fishermen accidently getting in other country’s terrestrial water, is very high. Hence, the fishermen and their families are always concerned about the safety of the human lives, boat and gears. Due to deep sea communication network we can continuously get oceanic condition information. Such real-time information about wind speed, direction and wave height can help to estimate the risks and avoid the ocean region which seems dangerous. As part of this initiative, we looked at various available communication technologies like VHF transceivers, satellite communication and cellular mobile communication. Central Marine Fisheries Research Institute, Tata Consultancy Service and Tata Tele Services formed a consortium and piloted a project to extend the mobile signal deep into the sea up to 30 kms. This extended network enabled continuous accessibility of life saving ocean state forecast information provided by INCOIS. Due to this an accessible Early Warning System (EWS) spread over a digital highway of 30 by 120 km, along Raigad coast. This paper captures the experiences and recommendations derived from this pilot

    File System Support for Privacy-Preserving Analysis and Forensics in Low-Bandwidth Edge Environments

    In this paper, we present initial results from our distributed edge systems research in the domain of sustainable harvesting of common good resources in the Arctic Ocean. Specifically, we are developing a digital platform for real-time privacy-preserving sustainability management in the domain of commercial fishery surveillance operations. This is in response to potentially privacy-infringing mandates from some governments to combat overfishing and other sustainability challenges. Our approach is to deploy sensory devices and distributed artificial intelligence algorithms on mobile, offshore fishing vessels and at mainland central control centers. To facilitate this, we need a novel data plane supporting efficient, available, secure, tamper-proof, and compliant data management in this weakly connected offshore environment. We have built our first prototype of Dorvu, a novel distributed file system in this context. Our devised architecture, the design trade-offs among conflicting properties, and our initial experiences are further detailed in this paper

    The Ecosystem Approach to Fisheries: Issues, Terminology, Principles, Institutional Foundations, Implementation and Outlook

    Get PDF
    Ecosystems are complex and dynamic natural units that produce goods and services beyond those of benefit to fisheries. Because fisheries have a direct impact on the ecosystem, which is also impacted by other human activities, they need to be managed in an ecosystem context. The meaning of the terms 'ecosystem management', 'ecosystem based management', 'ecosystem approach to fisheries'(EAF), etc., are still not universally defined and progressively evolving. The justification of EAF is evident in the characteristics of an exploited ecosystem and the impacts resulting from fisheries and other activities. The rich set of international agreements of relevance to EAF contains a large number of principles and conceptual objectives. Both provide a fundamental guidance and a significant challenge for the implementation of EAF. The available international instruments also provide the institutional foundations for EAF. The FAO Code of Conduct for Responsible Fisheries is particularly important in this respect and contains provisions for practically all aspects of the approach. One major difficulty in defining EAF lies precisely in turning the available concepts and principles into operational objectives from which an EAF management plan would more easily be developed. The paper discusses these together with the types of action needed to achieve them. Experience in EAF implementation is still limited but some issues are already apparent, e.g. in added complexity, insufficient capacity, slow implementation, need for a pragmatic approach, etc. It is argued, in conclusion, that the future of EAF and fisheries depends on the way in which the two fundamental concepts of fisheries management and ecosystem management, and their respective stakeholders, will join efforts or collide

    Review of existing and operable observing systems and sensors

    Get PDF
    Deliverable 1.4 is aimed at identification of existing and operable observing systems and sensors which are relevant to COMMON SENSE objectives. Report aggregates information on existing observing initiatives, programmes, systems, platforms and sensors. The Report includes: • inventory of previous and current EU funded projects. Some of the them, even if started before 2007, were aimed at activities which are relevant or in line with those stemming from MSFD in 2008. The ‘granulation’ of the contents and objectives of the projects varies from sensors development through observation methodologies to monitoring strategies, • inventory of research infrastructure in Europe. It starts from an attempt to define of Marine Research Infrastructure, as there is not a single definition of Research Infrastructure (RI) or of Marine Research Infrastructure (MRI), and there are different ways to categorise them. The chapter gives the categorization of the MRI, together with detailed description and examples of MRI – research platforms, marine data systems, research sites and laboratories with respect of four MSFD descriptors relevant to COMMON SENSE project, • two chapters on Research Programs and Infrastructure Networks; the pan-European initiatives aimed at cooperation and efficient use of infrastructural resources for marine observation and monitoring and data exchange are analysed. The detailed description of observing sensors and system are presented as well as frameworks for cooperation, • information on platforms (research vessels) available to the Project for testing developed sensors and systems. Platforms are available and operating in all three regions of interest to the project (Mediterranean, North Sea, Baltic), • annexed detailed description of two world-wide observation networks and systems. These systems are excellent examples of added value offered by integrated systems of ocean observation (from data to knowledge) and how they work in practice. Report concludes that it is seen a shortage of new classes of sensors to fulfil the emerging monitoring needs. Sensors proposed to be developed by COMMON SENSE project shall answer to the needs stemmed from introduction of MSFD and GES descriptors

    The precautionary principle : its implication in capture fisheries management

    Get PDF
    The paper attempts to clarify the research, management and legal implications of a potential application of the Precautionary Principle to capture fisheries, particularly in the international context. In the process, the paper also looks at related issues such as the burden of proof, the use of best available scientific evidence and technology, the reliance on prior scientific consensus, assimilative capacity and acceptable levels of impacts, etc., inthe fishery context. It is argued that, if narrowly interpreted, the Precautionary principle could lead to socio-economic havoc. If reasonably interpred, however, the Principle offers a golden opportunity to progress towards sustainable fisheries development and suggestions are made for the implementation of precautionary approaches in fisheries management.

    Sustainable seabed mining: guidelines and a new concept for Atlantis II Deep

    No full text
    The feasibility of exploiting seabed resources is subject to the engineering solutions, and economic prospects. Due to rising metal prices, predicted mineral scarcities and unequal allocations of resources in the world, vast research programmes on the exploration and exploitation of seabed minerals are presented in 1970s. Very few studies have been published after the 1980s, when predictions were not fulfilled. The attention grew back in the last decade with marine mineral mining being in research and commercial focus again and the first seabed mining license for massive sulphides being granted in Papua New Guinea’s Exclusive Economic Zone.Research on seabed exploitation and seabed mining is a complex transdisciplinary field that demands for further attention and development. Since the field links engineering, economics, environmental, legal and supply chain research, it demands for research from a systems point of view. This implies the application of a holistic sustainability framework of to analyse the feasibility of engineering systems. The research at hand aims to close this gap by developing such a framework and providing a review of seabed resources. Based on this review it identifies a significant potential for massive sulphides in inactive hydrothermal vents and sediments to solve global resource scarcities. The research aims to provide background on seabed exploitation and to apply a holistic systems engineering approach to develop general guidelines for sustainable seabed mining of polymetallic sulphides and a new concept and solutions for the Atlantis II Deep deposit in the Red Sea.The research methodology will start with acquiring a broader academic and industrial view on sustainable seabed mining through an online survey and expert interviews on seabed mining. In addition, the Nautilus Minerals case is reviewed for lessons learned and identification of challenges. Thereafter, a new concept for Atlantis II Deep is developed that based on a site specific assessment.The research undertaken in this study provides a new perspective regarding sustainable seabed mining. The main contributions of this research are the development of extensive guidelines for key issues in sustainable seabed mining as well as a new concept for seabed mining involving engineering systems, environmental risk mitigation, economic feasibility, logistics and legal aspects
