The most severe droughts  are associated with prolonged shortages of water and result in widespread crop and other vegetation losses. In this map, the region affected the most is shaded in dark depending on the vegetation stress faced. The image shows the number of weeks that areas across the globe have experienced exceptional drought vegetation stress, dating back to 1981 when NOAA’s satellites first began monitoring vegetation patterns. Areas above 60 degrees latitude and desert locations have been omitted from the analysis.
