Disasters take many forms. They may be in the form 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.
Information regarding disaster relief is maintained by our partners at the National Center for Appropriate Technology.
The Vermont Agency of Agriculture lists both Vermont and federal grants that are available to help.
