Lebanon’s 2024 4Ws Mapping Report shows that mental health needs remain extremely high, driven by years of overlapping crises, economic hardship, displacement, and the escalation of hostilities in 2024. While 54 organizations reported MHPSS activities through the 4Ws Platform, the findings suggest that service provision remains uneven, with stronger activity in Beirut, Mount Lebanon, North, and South, and much lower reported coverage in Keserwan-Jbeil. The response shows important strengths, including a diversity of providers, decentralized services, gender-balanced care, and support across different age groups and nationalities. However, gaps persist in equitable access, especially for older adults, substance use services, community-based emergency interventions, and governorates with fewer reported activities. The emergency response demonstrated the value of preparedness, coordination, frontline training, and continuity of essential services such as the National Lifeline, Step-by-Step, and access to psychotropic medication. At the same time, the report highlights challenges in data reporting, emergency service tracking, workforce shortages, and the need for stronger referral systems. Overall, the main takeaway is that Lebanon has an active and adaptive MHPSS response system, but it needs more sustainable funding, stronger community-based services, better emergency-ready data systems, and wider integration of mental health into primary care and national information platforms.
