Intended to be used by NGO field staff who work with refugees and displaced persons. It offers both basic legal information about international protection for refugees and practical guidance for including protection measures in all field operations. The Field Guide illustrates how protection concerns can follow refugees through every phase of their lives as refugees. In doing so, the Field Guide alerts NGO field workers to signs of possible protection problems during each phase of a refugee's life and suggests specific actions that could be undertaken to address those problems. Subsequent chapters of the Field Guide focus on Special Protection Issues. While many of the suggestions for action offered in these chapters can apply to all persons of concern, each particular population discussed in these chapters (women, children, older refugees, internally displaced persons and stateless persons) has unique needs and problems that require special consideration.
