Lagoons are characterized by an essential quality of uncertainty for use in resource management: these are physically vulnerable to various influences from not only the environment but also the adjacent marine and terrestrial areas. This book presents a variety of lessons learned from case studies from Asian countries (India, Japan and Thailand).

This report seeks to present a review of the current status of coastal governance with regard to its compatibility with Integrated Coastal Management (ICM) in Sri Lanka. The purpose of this review is to support the preparatory programme of work of the Mangroves For the Future (MFF) initiative, and as such represents one of several studies commissioned that are to feed into this planning process for each participating country. To this end, it is envisaged the report will provide a resource for ICM practitioners and policy planners who may be involved with the MFF process both at the national and regional levels.

This publication consist of case studies describing how socio-economic and demographic concerns are addressed in integrated coastal zone and community-based fisheries management in selected Caribbean countries - Belize, Dominica, Jamaica, Saint Lucia, Trinidad and Tobago and the Turks and Caicos Islands. The results of a comparative study in Malaysia and the Philippines are also reported, including the results of a regional workshop organized to review the findings of the case and comparative study.

The paper reviews the existing methods used in India for estimation of flow characteristics at ungauged sites. It focuses on low and high flows, long-term mean flow and flow duration curves. Since it lists the actual formulae, it can be used as a quick reference guide for selecting a suitable technique for various geographical regional and/or river basins in India.

The small-scale fisheries subsector is a crucial provider of livelihoods, nutrition, and food security to millions of people all over the world. However, small-scale fishers, fishworkers and their communities face many challenges, including lack of recognition, limited participation in decision-making, unsustainable use of aquatic resources, climate change impacts and conflicting interests with other sectors. The Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines) are the first international instrument entirely dedicated to small-scale fisheries and provide guidance on how to address existing challenges in the subsector. One of the key areas discussed in the SSF Guidelines is the need for an enabling environment that promotes good governance. This publication, Small-scale fisheries governance – A handbook in support of the implementation of the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication, was based on a number of training courses on governance in small-scale fisheries. It offers an overview of the SSF Guidelines and guidance on their implementation in particular with regard to good governance and the enabling environment needed.

The overarching objective of this report was to determine, from current evidence and experiences from the region, a view of co-management application and performance. Among the findings of the review are: (1) Co-management is associated with positive trends across a range of social, ecological and governance indicators; (2) While overall trends in co-management performance are positive, between years the outcomes experienced by fishers and community members vary substantially between positive experiences and improvements and negative experiences and declines; (3) There is substantial variation in the systems to which co-management is applied and the degrees of inclusion, agency, influence and authority of managing partners; (4) Impacts of co-management on environmental and resource condition, and on the livelihood and economic conditions are determined as much by macro-level drivers of change as by co-management; (5) Initiatives associated with improved or alternative livelihoods were frequent; (6) A history of institutional and policy change created conditions enabling co-management arrangements; (7) Co-management is associated with improvements to representation and inclusion of resource users and beneficiaries; (8) National and international commitments have been made to progress gender equity, women’s empowerment, and socially inclusive processes and outcomes; but substantial challenges remain in meeting them; (9) Co-management is generally associated with higher levels of buy-in and compliance by resource users; (10) Monitoring and evaluation should move towards best practice impact evaluation techniques; (11) Co-management arrangements for fisheries are widespread, diverse, dynamic and supported by a range of institutional structures and organizations.

This technical document has been developed in recognition of the increasingly diverse demands for water from irrigation systems and the need to introduce more holistic land uses into conventional irrigation management. Despite historical precedents and efforts in the twentieth and early twenty-first centuries, the potential for the integration of fish production (capture fisheries and aquaculture) and irrigation systems has yet to be fully realized. Capturing these underutilized opportunities for the integration of fisheries and aquaculture could significantly increase local economies, food security, household incomes and livelihood diversity within irrigated agriculture systems. To re-examine the potential of fisheries in irrigation systems, the concept of the extended command area (ECA) is used, expanding the conventional definition of an agriculture irrigation command area. The reason for this expanded definition is because all elements of an irrigation system, from upstream dam storage to downstream drainage areas, offer opportunities for increasing fish production. Many of these opportunities may be realized at no additional cost to the main irrigated crop. This document provides an introduction to the ways fisheries and aquaculture already co-exist with irrigation and explores the threats and opportunities that arise from this. A key concept for sustaining and enhancing inland capture fisheries is “connectivity”– a fundamental basis for ensuring adequate environmental conditions to allow fish to flourish within an aquatic ecosystem such as a river, lake, or wetland. Improving connectivity within an ECA can restore elements of ecological services that may have been compromised or degraded through irrigation, water management or through other rural infrastructure development such as road construction. Practical application of the integration of fisheries and irrigation systems is explored through the use of the Ecosystem Approach to Fisheries (EAF) in the context of irrigation systems. The proposed process links the development of an EAF management plan for fisheries to irrigation system operation and is given the acronym EAFm-i. A key part of this linkage is an assessment of water resources in the system and the management of water for delivery to fisheries. Additional tools to support the EAFm-i process are also described. Although the experience and approach are drawn largely from irrigation systems and inland capture fisheries in Southeast Asia, the application of the ECA concept and approach will be relevant to any irrigation or water management system where there is potential for the closer integration and harmonization of fisheries and irrigation systems and where water users are interested in realizing this potential. This short paper is intended to encourage fisheries and irrigation specialists to engage in greater dialogue and cooperation over the integration of fisheries into irrigation planning and to support piloting of an EAFm-i process, which can be the basis for further development.

Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.
