Various concerns relating to international humanitarian law and human rights were risen by natural catastrophes (tsunamis, floods, fires), the Covid-19 pandemic, the epidemic breakouts of Ebola, as well as the significant migrant wave observed in the Mediterranean region. Forensic Medicine has direct interactions with both domestic and international law, and thus is frequently asked to provide solutions for these issues. The term "Humanitarian Forensic Action" (HFA), which refers to the application of forensic science to serve humanitarian endeavors, was created. The management of crises including armed conflicts, natural disasters, and humanitarian crises is therefore related to HFA. HFA is a specialized field of forensic sciences that is used to handle the identification of the deceased and human remains, as well as to contribute to the management of the dead, the management of mass disasters, and the investigation of abuse and torture. The psychosocial effects that these tragic events have on the victims, their loved ones, and society at large represent another HFA-related field. Firstly this systematic review aims to present all available international literature that discusses HFA as a unique forensic discipline. Secondly, through this review, it is hoped that HFA awareness will be risen among forensic practitioners, thus allowing improved adoption in general and future development as a branch of forensic sciences. As far as we are aware, there isn't another systematic study that presents the entirety of HFA's branches at once.
