USAID Oceans developed this guide as a capacity building tool for its regional partners, including those from national and local government agencies, and other interested development and non-governmental organizations. The guide documents essential program knowledge and experiences to equip readers with the necessary skills and tools to undertake partnership development. USAID Oceans hopes that this guide will benefit and support regional institutions in their work with their respective member countries, as well as those working in other regions beyond Southeast Asia.
