Disaster management and insurance
Rural households in the affected region face ongoing economic vulnerability from potential future disasters, reduced agricultural capacity, livestock losses, and psychological trauma affecting labor productivity and investment in the region.
Cameroon may need to strengthen disaster early warning systems, invest in geological monitoring infrastructure, implement insurance mechanisms for natural disasters, and consider population relocation policies or economic diversification programs for vulnerable regions near volcanic lakes.
