Marine resources,biophysical processes,and environmental management of a tropical shelf seaway: Torres Strait,Australia–Introduction to the special issue     

P.T. Harris  A.J. Butler  R.G. Coles 《Continental Shelf Research》2008

This special issue of Continental Shelf Research contains 20 papers giving research results produced as part of Australia's Torres Strait Co-operative Research Centre (CRC) Program, which was funded over a three-year period during 2003–2006. Marine biophysical, fisheries, socioeconomic-cultural and extension research in the Torres Strait region of northeastern Australia was carried out to meet three aims: 1) support the sustainable development of marine resources and minimize impacts of resource use in Torres Strait; 2) enhance the conservation of the marine environment and the social, cultural and economic well being of all stakeholders, particularly the Torres Strait peoples; and 3) contribute to effective policy formulation and management decision making. Subjects covered, including commercial and traditional fisheries management, impacts of anthropogenic sediment inputs on seagrass meadows and communication of science results to local communities, have broad applications to other similar environments.  相似文献   

The emergence of a hybrid mode of knowledge production in the Generation Challenge Programme Rice Research Network (GCP-RRN) in India: Exploring the concept of Commons-Based Peer Production (CBPP)     

《Geoforum》2017

The Generation Challenge Programme (GCP) was an international agrarian knowledge-production programme created in 2003 by the CGIAR. GCP aims at developing drought tolerant varieties by reconciling upstream biotechnology based advanced research with the downstream development at the farmer's field. The objective of this paper is to apply the theory of Commons Based Peer Production (CBPP) to analyse the knowledge production process of GCP, especially the case of drought tolerant rice research network in Indian context (GCP-RRN). CBPP represents the theorisation of a mode of production that can be distinguished from market (private) and state (public) knowledge-production systems that was developed by observing the phenomena of Free and Open Source Software (FOSS). The organisational attributes of the CBPP mode applied in computer software production include the modulation of work, small-size granularity of components, and mechanisms that integrate these modules into an end product. Socio-economically, this form of production is based on cooperation, collaboration and collective action rather than property, contract and managerial hierarchies. This paper argues that GCP-RRN knowledge production is basically a hybridised one in which there are certain inclinations towards CBPP within certain larger context, and there are other attributes too that do not fall within CBPP theorisation. Further, this paper elaborates on the implications of this hybridised model for agrarian knowledge production discourse and institutions.  相似文献

海洋调查船是专门进行海洋调查研究的工具,研究内容囊括了海洋气象、水声、物理、化学、生物、地质和水文等诸多学科,是我国海洋强国战略以及"一带一路"顺利实施的重要保障。海洋调查船按照使用的目的分为综合调查船、渔业调查船和极地调查船等。文章在各类调查船中分别选取了国内外具有代表性的船舶进行对比分析,总结了国内各类型调查船的优势和不足,对我国各类调查船的发展方向具有较好的借鉴意义。同时,文章根据对国内外调查船调查能力的对比,提出了我国调查船发展的建议:(1)完善调查船类型;(2)提高各类型船舶调查能力;(3)增加相应类型船舶数量,达到我国海洋调查需求;(4)推动海洋调查仪器设备的国产化进程;(5)加强国家海洋调查船队运行管理职能。  相似文献   

Is there a need for a new governance model for regionalised Fisheries Management? Implications for science and advice     

《Marine Policy》2017

Over the years, the breadth and depth of EU marine policy has increased with revisions of the Common Fisheries Policy (CFP) and new legislation like the Marine Strategy Framework Directive (MSFD), Integrated Maritime Policy (IMP) and the Framework for Marine Spatial Planning Directive in Europe (FMSP). Not only do these different policies have different remits and hence scope, they also present a multitude of modes of implementation. Although the CFP and MSFD have many common goals when it comes to conservation and sustainable use of living marine resources, they differ substantially in governance set up and implementation modalities, including the underlying scientific advisory processes and structures. Regional cooperation and coordination is foreseen, but there is no governance model in place to coordinate requests for scientific advice, nor institutions coordinating the activities of advice providers, either across policies or across regions. This results in an increase in uncoordinated requests for scientific advice yet the pool of experts fuelling the advisory system is limited. As a result the European marine scientific advisory system is increasingly under pressure. In this paper the consequences of this problem are analysed and a redesign of the institutional governance setting to accommodate these challenges and make the science and advice system ready for the future is explored.  相似文献   

Writing the history of water services     

Tapio S. Katko  Petri S. Juuti 《Physics and Chemistry of the Earth》2009,34(3):156-163

This paper analyses the experiences acquired through several research projects on the history of water and sanitation services by two multidisciplinary teams. Challenges have been faced in identifying feasible objectives, realistic resources, time allocations and unexpected external factors. Water history can preserve cultural heritage, promote reputation management, record vanishing knowledge, and discover new facts.  相似文献
