This resource was developed to guide aging and disability networks in increasing their ability to plan for and respond to public health emergencies and disasters. This toolkit helps programs that serve people with access and functional needs, including older adults and people with disabilities, through the emergency planning process of preparedness, response, recovery, and mitigation activities. The Capacity-Building Toolkit can help organizations of all types conduct more inclusive emergency planning by facilitating personal preparedness among aging adults and people with disabilities and expanding organizational knowledge of the unique challenges facing these populations during emergencies. The Toolkit can also help emergency managers and public health officials to understand the capabilities and expertise of community-based organizations within the aging and disability network.
