This manual was prepared the FAO Regional Fisheries Livelihoods Programme for South and Southeast Asia (RFLP) funded by Spain to facilitate gender analysis and project planning in fisheries development projects and to help practitioners incorporate a gender perspective into all phases of small-scale fisheries development projects. It provides a toolkit to help project managers and implementing counterparts (such as extensionists, government and non-government field workers, and private- and public-sector development consultants, community organizers and leaders of local groups), to facilitate the integration of gender issues into the project cycle.   The handbook provides i) the rationale, concepts and approaches relative to mainstreaming gender equality into development cooperation; ii) an overview of the role of women in the fisheries sector in Southeast Asia, the problems they face and possible empowerment opportunities; tools for gender analysis in fisheries development projects and guidance on gender sensitive indicators and iv) mainstreaming gender at various stages of the project cycle. This manual has been published in English, Thai and Vietnamese languages. This manual is the Vietnamese language version.
