First of all, collaborative approaches are based on relationships. Thus, they are reinforcing populations resilience. They are also based on local initiatives to fulfill unmatched need and enable disruptive answers. Furthermore, they do not necessarily need huge financing, since they are based on recycling of funds (inside communities), in opposition with traditional assistance approaches. They even allow revenue generation, although they do not guarantee fair share of revenues. Thus, collaborative approaches are sustainable, opened toward change of practices, in a very different way of emergency responses. Finally, they do not stigmatise affected populations, since they are directly part of the process, as contributor (see for example http://singa.fr).
