The Division on Earth and Life Studies (DELS) is one of six subject area divisions of the National Academy of Sciences, Engineering, and Medicine that enlist the nation's top experts to respond to requests for advice from the Federal Government, states, and some foundations.

The division has 11 program units (boards) that undertake a wide-range of activities, including convening experts to share their individual views in meetings and workshops. However, it is the Academy’s reports that represent the most authoritative source of scientific and technical information for the nation. The division produces about 30-40 of these reports each year.
