Below is an announcement recently made by the Global Footprint Network; their latest paper on the methodology for the Ecological Footprint calculation has been accepted into an ecological journal titled Ecological Indicators. A direct link to the full PDF is included.
Much of the report explains algorithm design, but the results section states that “According to the 2011 Edition of the National Footprint Accounts, in 1961 humanity’s Ecological Footprint was approximately half of what the biosphere could supply annually; humanity was living off the planet’s annual ecological interest, not drawing down its principal. Since then, humanity’s overall Footprint has more than doubled, first exceeding the planet’s biocapacity in the early 1970s. This situation, known as overshoot, has continued to increase, reaching 52% in 2008.”
Latest Ecological Footprint methodology paper accepted for publication in Ecological Indicators
Global Footprint Network – 09/18/2012 10:39 PM
Every year, Global Footprint Network continues to improve the methodology for calculating the Ecological Footprint. The most recent Calculation Method paper has been accepted for publication in the journal Ecological Indicators: Integrating Sciences for Monitoring, Assessment and Management.
The paper documents the latest method for estimating the Ecological Footprint and biocapacity of nations, using the National Footprint Accounts (NFA) applied to more than 200 countries and for the world overall. Results are also compared with those obtained from previous editions of the NFA. According to the 2011 Edition of the National Footprint Accounts, humanity demanded the resources and services of 1.5 planets in 2008; this human demand was 0.7 planets in 1961.
Each new edition of the National Footprint Accounts supports the conclusion that we are in global ecological overshoot, where total demand for ecological goods and services exceed the available supply and regenerative capacity, while also causing carbon waste accumulation.
