Federal funding does not prevent natural disasters. Being the governor of Louisiana, Jindal knows this.
You are right, Federal funding does not prevent natural disasters. However, proper monitoring of potential dangerous events is extremely important. How many lives has the National Weather Service saved because of improvements in monitoring of developing hurricanes?
I am currently researching a historical novel covering the terrible Mt. Pelee eruption in Martinique in 1902 that killed close to 40,000 people, and the neighboring eruption of La Soufrier in St. Vincent that killed 2,000. In the process I have read a number of recent books on volcanic events. One fact that shows up repeatedly is the lack of monitoring equipment, and training of the people to use them, that would enable better predictions to be made regarding dangerous eruptions. It is important to note that the careful and terrifically courageous monitoring of Pinatubo that was done with the borrowed equipment from the USA kept this monsterous eruption from killing no more than 500 people. Unfortunately, most of the equipment was destroyed in the eruption.
