Portugal's Ecofootprint
Portugal's ecological footprint
is well above the world average... If everyone in the world consumed
resources and produced waste at the same level as the Portuguese,
we would need 3 planets to meet these resource demands and absorb
the accompanying pollution. Portugal's footprint is also unusually
high for its wealth level, i.e., most countries with such a large
footprint have a significantly higher per capita GNP. There is evidence
that the problem has been getting worse in recent years, with energy
comprising the main component of the country's footprint.
At the same time, Portugal has
been in the forefront of developing innovative solutions to reverse
this trend by reducing consumption levels and increasing resource
use efficiency and biocapacity. Specifically, the work done in Portugal
as part of the One Planet Living partnership promoted by BioRegional
and WWF is setting a global benchmark on ways society can achieve
both sustainable development and nature conservation.
ECOLOGICAL FOOTPRINTING:
FRAMING THE PROBLEM
- The Ecological Footprint is
a rigorous means of measuring how our lifestyles impact both the
planet and other people. It calculates how much productive land,
freshwater and sea is needed to provide all the food, water, energy
and materials we use in our everyday lives. It also calculates the
emissions generated from the oil, coal and gas we burn, and determines
how much land is required to absorb our wastes. By comparing rates
in different places, it gives a concrete measure of how the lifestyles
of some areas are affecting others, via their resource use and waste
production.
- The global Ecological Footprint
was 13.5 billion hectares in 2001, the most recent year for which
global figures are available, or 2.2 'global hectares' per person.
- This demand on nature can be
compared with the Earth's biocapacity, based on its biologically
productive area. This stands at approximately 11.3 billion global
hectares, or a quarter of the Earth's surface. The productive area
of the biosphere translates into an average of 1.8 global hectares
per person, making this the 'fair share' of the world's resources
available to each person.
- Comparing
these numbers shows that humanity's Ecological Footprint currently
exceeds global biocapacity by 0.4 global hectares per person, or
21 percent.
- This 'overshoot' means we are
consuming resources faster than they are being regenerated, and
are now eating into the earth's 'natural capital'. The end result
is the destruction of assets on which our economy and life itself
depends. Examples include disappearing forests, eroding soils, collapsing
fisheries, and falling water tables. A key manifestation of this
overshoot is climate change, which is causing an increase in the
frequency and intensity of extreme weather events.
- The problem
of overshooting existing resource capacity is particularly associated
with richer, industrialised nations. For example, if everyone in
the world lived as Americans do, we would need five planets to maintain
our lifestyle over time.
- Portugal is an example of a
country whose ecological footprint is greater than might be expected.
The country's per capita footprint is 18th in the global ranking,
above that of Germany or Japan. Moreover, the figures show that
current trends point toward a growing problem, with Portugal's footprint
35th in the global rankings just five years ago.
- The current
Portuguese footprint is equivalent to 5.2 hectares per person per
year, yet available global biocapacity is just 1.8 hectares per
person. In other words, if everyone in the world lived like the
Portuguese, we would need almost three planets (5.2 / 1.8
= 2.89) to meet our demand for natural resources and absorb our
waste and pollution.
- The figure of 5.2 hectares per person per year also represents
an increase in absolute terms, with figures for 3 years previously
standing at 4.5 hectares.
- At the
same time as our ecological footprint is increasing, the "Living
Planet Index" (LPI) is receding. The LPI is an indicator of
the state of the world's biodiversity. It measures trends in populations
of vertebrate species around the world, and currently tracks changes
in abundance of 555 terrestrial species, 323 freshwater species
and 267 marine species. Between 1970 and 2000, the index fell by
about 40 percent.
- While the LPI fell by some 40
percent between 1970 and 2000, the terrestrial index fell by about
30 percent, the freshwater index by about 50 percent, and the marine
index by around 30 percent.
- Over the
same period, the global Ecological Footprint grew by 70 percent
while the world's human population grew by 65 per cent.
RESPONDING TO THE FOOTPRINT
CHALLENGE
- Global ecological debt will
continue to grow as long as the Ecological Footprint exceeds biocapacity.
The resulting risk for humanity, and the Earth's biodiversity, can
only be ended by shrinking and ultimately eliminating the debt -
i.e., by living within the biocapacity of one planet.
- Measures
required to reduce our ecological footprint include:
- Improve the efficiency with which goods and services are produced
- Reduce per capita consumption of goods and services
- Increase biocapacity by conserving and restoring ecosystems, thus
maintaining biological productivity and ecological services.
- While
Portugal may be notable for its ecological footprint, it is also
notable for pioneering the global "One Planet Living"
initiative - a joint initiative of BioRegional and WWF that seeks
to put into practice just such measures via forming partnerships
with leading private companies.
- Groundbreaking work has been
done in Portugal to establish strategies to improve efficiency,
reduce consumption and increase biocapacity, as well as indicators
to verify progress. This includes proposals to increase protected
areas, restore degraded ecosystems, preserve wetlands, and eliminate
the use of toxic chemicals.
- As part
of the wider OPL initiative, the pioneering work of OPL Portugal
is a highly positive contribution not just to solving Portugal's
problems, but also the challenges facing humanity.
ONE PLANET LIVING COMMUNITIES
The challenge facing people everywhere
is to find ways to enjoy a high quality of life that does not exceed
the carrying capacity of our planet. For Portugal and other countries
with high a ecological footprint, this means finding ways to reduce
their footprint, notably by reducing consumption of fossil fuels
and virgin materials. For lower-income communities, it means enabling
growth in a sustainable way.
One Planet Living Communities
is a joint initiative of WWF and BioRegional Development Group that
aims to establish a set of sustainable communities in diverse contexts
around the world. Projects are delivered via partnerships with private
developers or public sector bodies, who must meet strict environmental
and social criteria. Work in Portugal is furthest advanced, but
is also underway in Australia, China, North America, South Africa
and the United Kingdom. The goal is to establish One Planet Living
communities on every continent by 2009.
If One Planet Living is to become
the norm around the world, it must be affordable and attractive
to a diverse range of peoples and cultures. It must therefore address
key human needs, including housing, clothing, food, healthcare,
education, energy, transport and leisure. One Planet Living must
also be easy - few people actually want to live unsustainably. However,
it is often too easy to make decisions that have damaging, unsustainable
consequences, and too difficult to choose more sustainable options.
To live at a one planet level, we need to be able to change the
'defaults' of our daily lifestyle decisions to ones that are sustainable.
To help humanity change course,
governments should act like any responsible business that keeps
track of its income and spending in order to protect its assets.
Specifically, they should keep ecological accounts, then pursue
policies that build on this information as a means to help protect
and restore the planet's natural assets. Via its communities, OPL
provides high-profile examples to government of what is possible
while also providing a basis for ongoing lobbying efforts.
Businesses and industry can play
an important role too. For example, they can switch from fossil
fuels to renewable energies and use efficient technologies, buildings
and transport systems. One Planet Living shows how environmentalists
and the market can work together to deliver innovative solutions
that can reverse our growing impact on the natural world without
compromising our quality of life.
One Planet Living builds on the
experience of the Beddington Zero fossil Energy Development (BedZED).
BedZED is an urban ecovillage in South London that has experimented
with diverse OPL-type solutions to practical challenges. For instance,
its homes are highly energy efficient, while units have private
gardens and conservatories despite their compact design. Residents
find BedZED a desirable place to live, contradicting the common
but erroneous assumption that a smaller Ecological Footprint means
a lower quality of life.
