Challenges of information sharing betweenaffected and supporting community
Multitude of data sources
Coupling of traditional with social media data
Aggregation and validation of data
Information not well adapted to local context
(illiteracy, language, documented expertise vs storytelling)
Technology gap
Using too advanced technology which does not ‘reach’ communities
Often one-way communication, with a very limited feedback loop
Collaboration gaps
Reluctance between actors to share information
Professionals versus volunteer communities
