HANPP Collection: Human Appropriation of Net Primary Productivity as a Percentage of Net Primary ProductivityEntry ID: CIESIN_SEDAC_HANPP_PERCENT
Abstract: The Human Appropriation of Net Primary Productivity (HANPP) as a Percentage of Net Primary Product (NPP) portion of the HANPP Collection represents a map identifying regions in which human consumption of NPP is greatly in excess of production by local ecosystems. Humans appropriate net primary productivity through the consumption of food, paper, wood and fiber, which alters the composition of the ... atmosphere, levels of biodiversity, energy flows within food webs and the provision of important ecosystem services. Net primary productivity (NPP), the net amount of solar energy converted to plant organic matter through photosynthesis, can be measured in units of elemental carbon and represents the primary food energy source for the world's ecosystems. This dataset is distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).
The data in Arc/Info GRID and GeoTIFF formats and maps in Portable Document Format (PDF) and Portable Network Graphics (PNG) format are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To identify spatial variations in the amount of NPP consumption relative to local production in a way that highlight humanity's growing impact on the biosphere.
