The CCHN Field Manual (2018) builds on the collective experience and perspectives of numerous humanitarian practitioners working in some of the most challenging conflict environments. It offers a set of concrete tools and methods to plan and prepare negotiation processes for the purpose of assisting and protecting populations affected by armed conflicts and other forms of violence. Through a series of in-depth interviews and informal professional exchanges with humanitarian practitioners from around the world, the CCHN has gathered a unique understanding of humanitarian negotiation practices.
