The 2020 Beirut explosion caused massive destruction to the city’s infrastructure, causing 204deaths as well as roughly 15 billion US Dollars in property damage. Lebanon has a lack of astandardized disaster response framework, leaving the Lebanese Army as the only mechanismfor disaster response in the country. This might work in smaller events and crises, but in adisaster, a large international mobilization is required, with clear and well-defined roles forevery contributor in the response. With the lack of a real disaster response framework in thecountry, a highly active civil society has evolved in the country. This is mostly due to thecitizen’s lack of faith in the government – a factor that led to a high number of volunteers andlocal NGOs participating in the response after the explosion. The purpose of this thesis was toexplore how the response after the Beirut explosion was organized. To do this I alsoformulated three research questions, dividing the response into three categories – government,international organizations, and local communities.With this thesis being constructed during the Covid-19 pandemic, fieldwork became virtuallyimpossible, meaning that all of the data collected and used in this thesis was gatheredthrough document studies and interviews.The theoretical framework of this thesis was focused on crisis management and otherstrategies for risk mitigation. With the response after the explosion being categorized on alarge number of volunteers and local NGOs, a fair amount of the theoretical framework wasalso dedicated to community based capacities. This was included to explore and analyze howthe local communities organized their response.The response after the 2020 Beirut explosion was mostly organized through an informaldecentralization due to the lack of a standardized disaster preparedness framework in thecountry. This meant that the international organizations had their own framework fororganizing their response, leading to a multi-sectoral response involving severalorganizations. The two largest contributors here were the UN and the Red Cross. The samewas the case regarding the local communities, who had to create their own crisis managementstructures to organize their response. With Lebanon already having a large number of NGOs,there were already several established organizational structures available with a basis forvolunteer mobilization, leading to a more effective response. Furthermore, many ad-hocstructures and initiatives were formed to coordinate the large number of volunteers.
