“It must be borne in mind, however, that, despite their destructive potential, floods are a natural part of both the hydrologic and the ecological systems of the West. Floodwaters carry nutrients and organic material that are deposited onto the surrounding floodplains, producing fertile soils. These soils have made California one of the most important agricultural centers in the world, generating $30 billion per year. More than half of the fruits, nuts, and vegetables consumed in the United States are grown on some 87,500 farms in California’s Central Valley. Nevertheless, residents in California and other regions of the American West continue to face risks from catastrophic flooding as they place themselves directly in the path of floodwaters, building their homes on floodplains that will inevitably be washed away in the next extreme wet year. To this day, cities sprawl onto the floodplains, housing developments pop up in the deltas, and homes are built on the edges of cliffs and canyons where landslides occur. Clearly, as Steinbeck indicated, society has collectively “lost its memory” of the earth’s climatic past.”
