Coordinating relief efforts entails minimizing the duplication of humanitarian services, whether by filling gaps or preventing overlap, and ensuring various organizations are synchronized to work together to achieve a common objective, thereby enabling a more coherent, effective, and efficient response. In relation to MHPSS coordination mechanisms, please refer to IASC MHPSS Guidelines action sheet 1.1 (page 33-37), and the IASC MHPSS Reference Group at mhpss.refgroup@gmail.com
