The Algeria Disaster Risk Management Diagnostic was developed as part of World Bank technical assistance to the Algerian government. The diagnostic offers a concise overview of the country's disaster risk profile, delves into the macroeconomic implications of disasters, outlines Algeria's advancements in disaster risk management (DRM), and highlights ongoing challenges within the DRM sector. This report aims to provide a comprehensive analysis of Algeria's DRM sector and identify key priority areas to enhance the country's resilience. This diagnostic was developed through a robust partnership between the World Bank and the National Delegation for Major Risks (DNRM) under the Algerian Ministry of Interior, Local Authorities and Territorial Development (MICLAT) from 2021 to 2023. It represents the culmination of an extensive review of over 500 documents, a comprehensive multi-stakeholder consultation workshop conducted in July 2021, and bilateral interviews held between March and October 2021 with the DNRM and all DRM stakeholders in Algeria. An initial version was completed in November 2021, which was further refined in 2022 and 2023 based on feedback received from Algerian counterparts through additional discussions, email correspondences, and recommendations from World Bank experts.
