This satellite image of the Jornada Basin in southern New Mexico, near Las Cruces, demonstrates the complexity of arid landscapes. To the lower left, green rectangles represent agricultural lands along the Rio Grande, and the dark area at the bottom left depicts the Doña Ana Mountains, an isolated range with a peak height of 1778 meters at Summerford Mountain (32.514°, -106.821°). Throughout the image, green shapes show areas where plants (grasses and shrubs) have greened up following rains. Brownish-white streaks show lands that have been affected by wind. Finally, on the right-hand side of the photograph, small dark arroyos can be seen that run with water when it rains in the mountains that emanate from just outside of the photograph's frame. In a Special Section in this issue, several articles discuss arid landscapes research, management, and education challenges and opportunities, as well as the drivers of the vast heterogeneity that they encompass. Photograph: Landsat 8 OLI/TIRS Surface Reflectance (18 Sept. 2016) acquired from the US Geological Survey.
