We
live in a globalized world characterized by constant crises in numerous social
and geographical areas. Political instability, climate change, overpopulation,
uncontrolled migration, poor governance, crime, as well as many other factors
create the circumstances from which crises can develop. Each crisis given its
causes and possible consequences requires different approaches and response
systems. This research focuses on considering modern technological solutions
that have the purpose of alerting and protecting individuals from risks and
threats that can lead to their suffering, caused by natural,
technical-technological and anthropogenic crisis events. It also aims to link
the theory of human security and the big data concept and present their application
through the development of the early warning system for crisis management in
the Republic of Croatia. This research has significant value because it analyses
and describes the establishment of a particular system in the world.
