scipsy: On the edge of the Kalahari Desert in Namibia, sand dunes are encroaching onto once-fertile lands in the north. Healthy vegetation appears red in this image; in the center, notice the lone red dot. It is the result of a center-pivot irrigation system, evidence that at least one optimistic farmer continues to work the fields despite the approaching sand.This is a false-color composite image made using near infrared, red, and green wavelengths. The image has also been sharpened using the sensor’s panchromatic band.  (via earthobservatory)
