Human Appropriation of Net Primary Production
This figure appears in the Our Changing Planet: The U.S. Climate Change Science Program for Fiscal Year 2006 report.
Average annual terrestrial NPP (i.e., ‘supply’) based on 17 years of AVHRR satellite data (top); global distribution of human-appropriated NPP (HANPP, i.e., ‘demand’) for all food and fiber products (middle); and NPP-carbon balance (HANPP as a percent of NPP, calculated for each grid cell) (bottom). Highly populated areas (yellow and red) consume up to 300 times their local production. Credit: M. Imhoff, NASA/ Goddard Space Flight Center.
