The major civilian United States Government (USG), intergovernmental organizations (IGOs), and nongovernmental organizations (NGOs) that play key roles as donors and implementing partners are discussed in the handbook. Understanding the complexity of the “state reconstruction” environment will assist planners in achieving a more unified effort with major stakeholders. This handbook also includes assessment and evaluation tools, lists of crucial planning considerations, military tasks matrices, and principles of practice. Vignettes and case studies, informed from on-the-ground experiences, illustrate key concepts and best practices. A special topics section discusses the strategic relationships between governance operations and counterinsurgency, political reconciliation, SFA, SSR, and ungoverned areas.
