Humanitarian aid is currently experiencing a major economic and organizational crisis. Initially direct aid has been prioritized and standardized with a view to efficiency, making it counter-productive and exposing it to numerous criticisms. This is why we are currently witnessing a refocusing on the ethics of action, one of the most explicit symptoms of which seems to be the increasing attention paid to resilience. It becomes problematic, then, to ask how ethics in humanitarianism contribute to building the resilience of the vulnerable for socially sustainable development. Based on the hypothesis that ethical humanitarianism plays an important role in building the resilience of beneficiaries towards sustainable development, this work attempts to assess the extent to which ethical humanitarianism contributes to the resilience of the vulnerable. This work attempts to assess the impact of ethical humanitarianism on the level of resilience and development of beneficiaries through a sample of 300 beneficiaries.
