This policy brief highlights the urgent need for Tanzania to strengthen its domestic resources to finance the health sector, as foreign aid continues to decline rapidly. It explores the importance of raising the bar in mobilizing enough resources from within Tanzania to finance the health sector. Despite a notable contribution from external sources, it has recently been confirmed that foreign aid is declining at a shocking pace. The Policy Brief at hand underscores the urgent need of bolstering internal health financing mechanisms as foreign aid continues to wane. It is therefore produced as an advocacy tool to alert the general public and influence policymakers on the need for deliberate efforts, viable policies, and workable strategies for enhancing DRM to locally finance critical health services. At the end, the policy brief recommends a strategic overhaul of Tanzania’s domestic resource mobilization strategy.
