Disasters take many forms. We may be talking about the impact of floods, storms, fires or other large scale events that can devastate crops and farms. When disasters strike, there is often some form of disaster relief provided by the federal ad State government, as well as no-profits. Some of this relief will be specific to the particular disaster, so you should check this site for updates at those times.

The Vermont Agency of Agriculture lists both Vermont and federal grants that are available to help.
