Human Appropriated Net Primary Productivity in U.S. Agriculture

2019 Winter Cyberseminar Series

Chris Lant / Utah State University

Talk Description

As the first in the FEWSION series, this presentation will begin by identifying objectives of food-energy-water systems models guiding by four key findings: (1) they engage ecological, carbon, water and nutrient cycles most powerfully among all human systems, (2) they operate primarily at a meso-scale best captured by counties, districts, and cities, (3) cities are hubs within the FEW system that (4) forms a complex network (see Lant et al 2018. Ambio  The presentation will then provide a description of work in progress on a critical component in FEW systems: Human appropriation of net primary productivity (HANPP).  As a next-generation measure of ecological footprint, HANPP serves an analogous function as carbon and water footprints and, like virtual water, can similarly be linked with trade patterns in the form of embodied HANPP.  An example of an empirical analysis of HANPP will focus on U.S. crop production.

CUAHSI's 2019 Winter Cyberseminar Series: The U.S. Food Energy and Water System at the Mesoscale

Hosted by Benjamin Ruddell, Northern Arizona University

The Food, Energy, and Water (FEW) system in the United States is characterized by connections at all scales, but especially by connections at the mesoscale defined by watersheds, cities, irrigation districts, and counties. At these scales transfers of water, flows of goods and services, and socio-economic gradients form the patterns that capture most of the structure in the complete FEW system. This cyberseminar series presents the current work on the mesoscale FEW system in the U.S., including studies of its network structure, its embedded resources and footprints, its boundaries, its stakeholders, its vulnerability and resilience dynamics, and emerging data products and best practices.
