As Humanitarian Adviser in a UN agency, my daily job requires increasingly a knowledge of IHL in dealing  – as of today – with the Syrian Crisis, engaging with non-state elements, dealing with armed forces parties to conflicts. Since 24 years, IHL has been at the basis of my profession having been involved in the main humanitarian response in conflict areas and complex situations. The relevance of IHL is expressed in the strategic planning of humanitarian interventions, as well the field operations that I am coordinating. Linkages between IHL and international human rights law (IHRL) are essential in the complex environment I am daily called to deal with.
