NFA Calculation Methodology
Land cover data
Hectar to global hectar(gha)
Yn=yield for anation
YF=yeild factor (comprison of yield) (Yn/Yw)
EQF=equivalence factor (comprsion of dif.land types)
The FAO Global Agro-Ecological Zones (GAEZ)
National Footprint Account (NFA)
As our global ecological overshoot gorws, how will countries countinue to meet the needs of their economies? Maintaining natural wealth and reducing ecological demand will help countiries improve economic resilience and human well-being
Our Ten-in-Ten campaign is engaging national governments to establish the Ecological Footprint as a prominent, globally accepted metric as ubiquitous as the GDP
GFN was established
in Oakland, California
The ecological footprint concept and
calculation method was developed by
under William Rees' supervision
at the University of British Columbia
in Vancouver, Canada,
90 partners in 19 countries,
hundreds of individuals,
200 cities, 23 nations,
leading business, scientists, NGO’s, academics
working to achieve large-scale change

How much land area does it take to support your lifestyle? Take this quiz to find out your Ecological Footprint, discover your biggest areas of resource consumption, and learn what you can do to tread more lightly on the earth
EF by household consumption
a resource-constrained world
One planet economy
improve their market foresight,
set strategic direction,
manage performance, and
communicate their strengths
*NFA 2010 and earlier based on distributional assumption
-NFA 2011 likely based on spatial data

We are ecological accountants working across the globe
Global hectare (gha): the area-weighted average productivity of biologically productive land and water in a given year.
A measure of how much biologically productive land and water an individual, population or activity requires to produce all the resources it consumes and to absorb the carbon dioxide emissions it generates using prevailing technology and resource management practices.
The capacity of ecosystems to produce useful biological materials and to absorb carbon dioxide generated by humans, using current management schemes and extraction technologies.
A productivity based scaling factor that converts a specific land type (such as cropland or forest) into a universal unit of biologically productive area, a global hectare.
Equivalence factor (EQF)
