    Assessment of the use of space technology in the monitoring of oil spills and ocean pollution: Technical volume. Executive summary

    Get PDF
    The potential of space systems and technology for detecting and monitoring ocean oil spills and waste pollution was assessed as well as the impact of this application on communication and data handling systems. Agencies charged with responsibilities in this area were identified and their measurement requirements were ascertained in order to determine the spatial resolution needed to characterize operational and accidental discharges. Microwave and optical sensors and sensing techniques were evaluated as candidate system elements. Capabilities are described for the following: synthetic aperture radar, microwave scatterometer, passive microwave radiometer, microwave altimeter, electro-optical sensors currently used in airborne detection, existing space-based optical sensors, the thematic mapper, and the pointable optical linear array

    The potential of geographical information system-based modelling for aquaculture development and management in South Western Bangladesh

    This study describes the delineation of appropriate sites for aquaculture using remote sensing, GPS and GIS. A 1996 composite Landsat TM image covering the south-western part of Bangladesh was used to identify water bodies, the extent of brackish water and associated land use features in the image. The Remote Sensing image was complemented by digitised secondary data from a range of sources, including hard copy maps to produce a GIS database which included environmental layers such as water bodies, rivers, soils, land use, temperature, rainfall, salinity and pH. The database also included infrastructural issues, such as roads, railways, processing plants, towns and cities. A series of GIS models were developed in order to identify and prioritise the most suitable areas for freshwater prawn, tilapia and carp and brackish water shrimp and crab farming. A range of scenarios for land allocations were used to develop a series of resource use models linked to likely production outcomes. Global warming and accelerated sea level rise is considered in the study area with different sea level rise scenarios of 50, 100, 150 and 200cm. The consequence of land losses and displacement of the population from the area in different situations is discussed. The economic characteristics of shrimp farming and alternative land uses in the Khulna region were also considered. Five land use options were studied based on economic output and job potential. Among these, brackish water shrimp and crab culture, moderately saline tolerant tilapia and prawn culture, fresh water carp culture and traditional rice production systems, and fresh water prawn culture performed best followed by brackish water shrimp and crab culture. This study showed the extent of potential for aquaculture in the Khulna region and further demonstrates the usefulness of GIS as an aquaculture-planning tool. Model programming was also found to be very useful tool to enabling regenerating of multiple scenarios very quickly. Overall, GIS modelling associated with remote sensing has great potential for informed decision-making in aquatic production systems and optimising management of natural resources in a region where they are already under considerable pressure. The implications for use of these systems in reducing land use conflict and sector planning for the region are discussed

    Proceedings of the 9th International Conference on Monitoring and Management of Visitors in Recreational and Protected Areas (MMV9), Bordeaux, FRA, 29-/08/2018 - 31/08/2018It is our pleasure to welcome you to the 9th international Conference on Monitoring and Management of Visitors in Recreational and Protected Areas (MMV9) with a program including keynote speeches, organized and poster sessions, a half-day field trip, social events and post conference trips. This is the first time that France has hosted an MMV Conference. Our country is ranked as the world's top tourist destination, thanks largely to its culture, art, and gastronomy, as well as popular cities such as Paris and Bordeaux. On the other hand, France's potential as a destination for outdoor recreation and nature-based tourism is not hugely publicized, despite its many unique features in this respect: varied climate and natural assets (shoreline, mountains, lakes, and forests), large expanses of countryside, and a network of protected natural areas, to name but a few. France's protected areas are often free to access for the general public. However, in contrast with other countries, nature conservation in specific areas is much less widespread. Where it does take place, it is often centered on territories that are perceived to be "attractive", and where many conflicting activities are practiced. This may be one of the reasons why contractual tools and regional park systems are quite popular in France. The MMV Conference offers an excellent opportunity to discuss the situation in France in greater depth. The theme proposed for the conference was "recreation, place and local development". This reflects our assumption that recreational areas are not just physical assets designed to receive visitors for the purpose of leisure - which in itself would already be something of great importance - but that they reflect deeper social phenomena, as demonstrated through the range of organized sessions dedicated to discussing questions such as environmental education and economic development, but also emerging themes such as social integration, community resilience, environmental justice, and health. The traditional topics covered by MMV Conference reflect an evolving society: with innovations in monitoring techniques (both on people and nature), focus on new populations (Y generation, ethnic minority) and a larger concern for individual engagement and participative management. The 9th Edition of MMV is co-hosted by Irstea and BSA. This would not have been possible without significant contributions from a large number of additional partners and sponsors as well as our national scientific and organizing committee. We would like to take this opportunity to thank everyone for their help. After two years of planning, we are proud to announce that we have more than 160 presentations from 30 countries, meaning that the conference will host over 200 participants from across the globe. We are honored that the International Steering Committee has given us the opportunity to be part of this great MMV community, which organized its first meeting in 2002. We hope you will enjoy the conference as much as we enjoyed organizing it. If you can't be with us in person, we hope that you will enjoy reading our publications

    Maritime expressions:a corpus based exploration of maritime metaphors

    Get PDF
    This study uses a purpose-built corpus to explore the linguistic legacy of Britain’s maritime history found in the form of hundreds of specialised ‘Maritime Expressions’ (MEs), such as TAKEN ABACK, ANCHOR and ALOOF, that permeate modern English. Selecting just those expressions commencing with ’A’, it analyses 61 MEs in detail and describes the processes by which these technical expressions, from a highly specialised occupational discourse community, have made their way into modern English. The Maritime Text Corpus (MTC) comprises 8.8 million words, encompassing a range of text types and registers, selected to provide a cross-section of ‘maritime’ writing. It is analysed using WordSmith analytical software (Scott, 2010), with the 100 million-word British National Corpus (BNC) as a reference corpus. Using the MTC, a list of keywords of specific salience within the maritime discourse has been compiled and, using frequency data, concordances and collocations, these MEs are described in detail and their use and form in the MTC and the BNC is compared. The study examines the transformation from ME to figurative use in the general discourse, in terms of form and metaphoricity. MEs are classified according to their metaphorical strength and their transference from maritime usage into new registers and domains such as those of business, politics, sports and reportage etc. A revised model of metaphoricity is developed and a new category of figurative expression, the ‘resonator’, is proposed. Additionally, developing the work of Lakov and Johnson, Kovesces and others on Conceptual Metaphor Theory (CMT), a number of Maritime Conceptual Metaphors are identified and their cultural significance is discussed
