The Emergency Management Agency (EMA) exists to implement mitigation, preparedness, response, and recovery programs for Jackson County.

During periods of non-emergency, the EMA works in the area of emergency mitigation and preparedness.

Functions include:
- Identification of hazards and their potential impact on Jackson County, as well as steps taken to lessen the impact, including education and awareness
- Emergency plan development and testing

During a disaster, the EMA will coordinate efforts to respond to, and recover from, the effects of the crisis. Responsibilities include providing the Chairman of the Jackson County Board with current conditions of the incident and to provide data necessary for declaration and termination of a disaster. In addition, the EMA coordinates support from other local jurisdictions, Illinois Emergency Management Agency (IEMA), and the Local Emergency Planning Committee (LEPC).
