For even more details go to Incident and Emergency Management Market.
With all that great news (?) on the industry and need for products and services, why can't you find a job? Several factors will dominate. One is that currently the coronavirus is putting a damper on things. I saw a report that all governments have seen a reduction of 500,000 jobs since the virus hit. Some of those will be in emergency management. The other thing to watch for is that as positions become vacant, they will remain vacant as governments capture the salary savings.
Last, you have to go where the jobs are. If it is an industry where things are booming, get the education and experience to be successful there versus in government.
Disease and climate change may be two primary drivers for growth in the future. How can you "take advantage" of that possibility?
