Soil is the foundation of our food systems, and sustainable farming depends upon healthy soil, which has impacts far beyond the field on air, water and climate. Wind and water, hastened by human activity and climate change, erode the richest soil at the surface.

With that possibility in view, California governor, Edmund G. Brown, Jr. declared a state of emergency on January 17, urging Californians to conserve water.

From brown landscapes to the bare mountains, California is clearly dry in this view from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite, taken on January 18, 2014. The lower image, taken on January 18, 2013, contrasts last year’s drought conditions with the extreme conditions currently in place. Read more
