How did Roosevelt counter the effects of the "Dirty Thirties" with proof to back it up?

The Dirty Thirties was a period a series of severe dust storms that damaged over 100 million acres of land in the United States and Canada. This led to a drought that devastated the agriculture industry in the US. When farmers were forced to abandon their land, it led to a serious food shortage. Franklin D. Roosevelt was elected President in 1933 and started many programs to combat the negative consequences of the dust storms.
One way that Roosevelt combated the Dirty Thirties was to alleviate the plight of the migrants and rural poor. He accomplished this through agencies like the Farm Security Administration and Resettlement Administration. These agencies set up public housing for migrant farmers and tried to regulate the market for crops. Roosevelt also combated the Dirty Thirties by focusing on the root causes of the Dust Bowl.
The Dust Bowl was caused by poor land use practices that made the farmland in the American Midwest highly susceptible to erosion. The Roosevelt Administration established several agencies to focus on "soil conservancy." The Prairie States Forestry Project created a "shelter belt" from the Texas Panhandle to the Canadian border. A shelter belt is a line of trees or shrubbery that prevents the erosion of soil by blocking strong winds. In addition, the US Forestry Service and Civilian Conservation Corps (CCC) worked together to plant over 200 million trees around individual farmlands in the Midwest. These are some of the ways that Roosevelt countered the effects of the Dirty Thirties.
