It demonstrated the relationship between weathering, erosion, and the biosphere. By removing the native vegetative cover of large areas of the Great Plains and converting it to wheat farming, an unsustainable land use caused the destruction of top soil and the destruction of the farm enterprises that were dependent upon the soil. The result was the concept of soil conservation and changes in agricultural practices.

The other significance of it is that it demonstrates how changes in land use by agriculture can contribute toclimate change. NASA studies have shown that the Dust Bowl climate was related to sea surface temperatures, but also that land use practices of the time created a feedback system in the climate that made the droughts worse than they would have been if natural land cover had been preserved.
