    RAFMS (Rapid Appraisal of Fisheries Managment Systems) designed by ICLARM is a semistructural research tool designed to quickly document and evaluate exisiting local-level fisheries management systems in a given coastal community. The results of RAFMS will provide direction for undertaking more formal research or quantitative surveys to describe institutional arrangements and performance. RAFMS is suited to the village level, or to a cluster of villages within a defined marine unit such as a bay. It's emphasis is on the evaluation of the rights and rules system governing the use of the fisheries resources at the local level. The approach is also participatory because it is designed for the joint use of RAFMS practitioners and local researchers in collaboration with local fishing communities. The mode of community participation, however, is consultative. This Version 1 of the guide was published with the anticipation of future feedback. Version 1 had been tested for two years prior to being published in collaboration with ICLARM's research partners at: Ulugan Bay and Binunsalian Bay in Palawan, Asia (Southeastern)-Philippines; and Nolloth Village at Saparua Isalnd in Indonesia

    Strategic Review of Tropical Fisheries Management

    This project addresses the constraints to tropical fisheries development with sustainable exploitation through a strategic assessment of tropical fisheries management with the following purposes: (1) To evaluate relevant research methods for the development of assessment models appropriate to the circumstances of tropical coastal fisheries; and (2) To evaluate the utility of existing strategies for the implementation of management advice. The report consists of three substantive chapters. Chapter 2 contains a detailed socio-economic assessment of various instruments and implementation strategies applicable to tropical capture fisheries. In Chapter 3, a detailed assessment of the fisheries for tropical large marine ecosystems has been conducted using a technique developed by FAO (Granger & Garcia 1996). The data used were the FAO statistics published regularly by FAO. This analysis has been conducted for each of the tropical large marine ecosystems and indicates that there is the potential for increased fishing in a number of these ecosystems. One of the clear requirements identified in Chapter 2 and implicit in Chapter 3, is that there is a significant need for simple and robust fisheries assessment methods which can estimate the potential of a particular resource, its capacity in terms of the level of fishing effort and its current status ie whether it is currently exploited sustainably or not. In Chapter 4, these problems are addressed directly and, using two approaches, significant simplification of fishery methods is developed. In the first approach, simple empirical relationships between the life history parameters of a species are used to develop models of potential yield which can be determined by a simple assessment of fish growth. In the second approach, optimal life history theory is applied to the key demographic parameters of exploited fish populations and using estimates of the Beverton & Holt invariants a significant simplifying of the basic stock assessment equations is developed

    A problem structuring method for ecosystem-based management : the DPSIR modelling process

    Get PDF
    The purpose of this paper is to learn from Complex Adaptive Systems (CAS) theory to inform the development of Problem Structuring Methods (PSMs) both in general and in the specific context of marine management. The focus on marine management is important because it is concerned with a CAS (formed through the interconnection between natural systems, designed systems and social systems) which exemplifies their particularly ‘wicked' nature. Recognition of this compels us to take seriously the need to develop tools for knowledge elicitation and structuring which meet the demands of CAS. In marine management, chief among those tools is the DPSIR (Drivers - Pressures - State Changes - Impacts - Responses) model and, although widely applied, the extent to which it is appropriate for dealing with the demands of a CAS is questionable. Such questioning is particularly pertinent in the context of the marine environment where there is a need to not only recognise a broad range of stakeholders (a question of boundary critique) but also to manage competing knowledge (economic, local and scientific) and value claims. Hence this paper emphasises how a CAS perspective might add impetus to the development of a critical perspective on DPSIR and PSM theory and practice to promote a more systemic view of decision-making and policy development

    New Approaches to Participation in Fisheries Research

    Get PDF
    This study was commissioned by FAO (Food and Agriculture Organisation of the United Nations) and SIFAR (Support Unit for International Fisheries and Aquatic Research) on the recommendation of the Advisory Committee on Fisheries Research (ACFR). It is concerned with research in the context of fisheries development.The ACFR acknowledges that the fisheries sector is faced with serious social and environmental problems and that current approaches to research have their limitations. It is recognised that participatory approaches and methods potentially have a greater role to play in fisheries research. This study aims to explore that potential and to suggest how we might move forward. The main focus of the report is on experiences in developing countries because this is where much of the innovative work in participation in research is being carried out. However, it is acknowledged that there is also much to be learnt from developed world experience

    Global fisheries governance and case study of fisheries governance of Autonomous Region of European Union – Azores

    Get PDF
    This article seeks to identify the key principles that should guide the definition of the Global Fisheries Governance and Management. A particular focus for this work has been the concept of participative governance and the co-management systems in which responsibility for management is shared between the world, regions, states and user groups, usually at the local level. Governance in the context of fisheries is divided in this article to three levels: the first dealing with issues of legal instruments, the second concerned with institutions and the third focusing on the construction of mechanism of management, in terms of economic, social and environmental values and principles to guide fisheries policy making along a consistent path of case study of fisheries governance in Azores.N/

    Comparison of Approaches to Management of Large Marine Areas

    In order to learn more about the different approaches to managing large-scale marine areas, their comparative merits, and the synergies and overlaps between them, Conservation International (CI) commissioned this independent analysis of several widely applied models. Since 2004, CI, together with a multitude of partners, has been developing the Seascapes model to manage large, multiple-use marine areas in which government authorities, private organizations, and other stakeholders cooperate to conserve the diversity and abundance of marine life and to promote human well-being. The definition of the Seascapes approach and the identification of the essential elements of a functioning Seascape were built from the ground up, informed by the extensive field experience of numerous marine management practitioners. Although the report was commissioned by CI, the views expressed in this report are those of the authors; they were charged with providing a critical examination of all the assessed approaches, including the Seascapes approach. This analysis provides a comprehensive understanding of the strengths and weaknesses of each approach. This will help us -- and, we hope, other readers -- to identify ways to work together to achieve even greater results through synergistic efforts
