The Asian Pacific unit footprints in 2008 are presented in the last WWF Living Planet Report. They are closely related to the country achieved development. The absolute footprint levels- after factoring by the population- are necessary to assess the growing unbalance within the Asian Pacific territory.
Asian
Pacific Population distribution
Asia
Pacific area covers three distinctive ecozones: Indomalaya, Australasia and
Oceania with extremely inhomogeneous population distribution (see figure 1):
o
3
hugely populated countries (200- 1400 mil): China, India & Indonesia with
are around 74% of Asian Pacific population;
o
6
big countries (50-190 mil): Pakistan, Bangladesh, Japan, Philippines, Thailand,
Vietnam altogether about 17% ;
o
14
intermediate countries (1-45 mil): all around 9% on which South Korea, Myamar,
Nepal, ,Malaysia - where I live -, Australia,
North Korea, Sri Lanka, Cambodia, Lao, Papua, Singapore, New Zealand, Mongolia,
Timor Leste;
o
Then
we have around 15 very small countries (< 1 mil): mostly tiny islands which
are presented as one group: Brunei, Maldives, Fiji,
Polynesia, New Caledonia, Micronesia, Tonga, Vanuatu etc..
Figure 1 |
The unit
footprints (see Figure 2) are measured in gha per person. They are closely
related to the country achieved development. Australia & Singapore's are
the highest and very similar to US or Canada footprints. Mongolia footprint is
also very high and this maybe is due to the huge amount of coal burning. South
Korea, Japan, New Zealand even Malaysia are intermediary high and similar to EU.
After, there are a group of 3 countries - around 2 gha per person- with
Thailand, China and New Guinea. The remaining 13 countries are in the range of 1 gha per person including Indonesia (1.14), Philippines (0.99), India (0.87)
and Pakistan (0.75).
On the
other hand the highest unit biocapacity are located in Mongolia, Australia, New
Zealand which are huge countries but with small populations that could be
considered as “sources” of biocapacity for the other ones.
Is this
a fair presentation concerning Singapore which is mostly an urban area with a
very limited biocapacity? We know that the City-State has greatly improved its
environment notably limiting car traffic, developing mass transport, building
water protecting and cleaning capacities. A comparison with other city
including Honk Kong or Kuala Lumpur should certainly be more relevant.
Figure 2 |
Absolute footprint and Asian Pacific
biocapacity unbalance in 2008:
The
absolute footprint levels (as opposed to the unit levels) are more pertinent to
assess the unbalance with the various territory biocapacities which are mostly
an attribute of their size and climate conditions.
We can
derive the country absolute footprint by factoring the above unit footprints by
the population (see figure 3). The situation is completely different and mostly
impacted by 7 countries: Chinese, India, Japan, South Korea, Indonesia,
Thailand and Australia which together amount to 5254 mil gha representing more
than 85% of the overall Asian Pacific footprint.
Figure 3 |
It looks
like the Asian Pacific area is the biggest “sink” of biocapacity in the Planet with
an unbalance around 2 883 mil gha which
is more than twice the EU sink value (1 228 mil gha) or 4 times de North
American sink value (730 mil gha).
Furthermore, we
know that the "global" ecological footprint as
proposed by the WWF is not very representative for
Asia-Pacific region which development is based on an
export-oriented model aiming the richest countries. The latest
phase of globalization destroyed many industrial jobs in high-income
countries and the greater part of them were relocated to Asia Pacific.
So the
“real” footprint including biocapacity inputs in all the GDP and not only in
household consumption should worsen the unbalance.
The WWF Living Planet Index in Asian
Pacific
The WWF Living
Planet Index is a composite indicator that measures changes in the size of
wildlife populations to indicate trends in the overall state of global
biodiversity. These measures of biodiversity of each ecosystem echo and clearly
confirm the dramatic reduction in biocapacity in the Asian Pacific Ecozone in
recent years.
Even if
the Indopacific zone is one of the richest for living animals and species, its Living
Planet Index as established by WWF declined by 64% during the last 40 years.
While in the same period the WWF LPI for the overall Planet decreased by only 28%.
Asia Pacific has the biggest reduction for all terrestrial, marine or fresh
water populations or species monitored by WWF.
These
declines reflect large scale forest and other habitat loss across these realms,
driven by logging, growing human populations, and agricultural, industrial and
urban development. Tropical forest cover declined most rapidly in Southeast
Asia between 1990 and 2005, with an estimated 0.6-0.8 per cent loss per year.
Asia Pacific Footprint in 2008 and
Evolution since 2005
What is
2008 Asian Footprint made of?
We see
(Figure 4) that the two biggest components in the Footprint are the CO2 and the
Cropland expressed in hectare of ground land and forest needed for growing crop
or absorbing the released Carbon. The Carbon is also time-wise the more dynamic
component: on the last 10 years there was an absolute two fold increase.
Figure 4 |
The
unbalance with biocapacity is mostly produced by Carbon release. The
CO2 exceeding the natural absorption of forest and water biocapacity is stored
in the atmosphere and leads to a deterioration of climatic
conditions: GHE temperature rise, instability, extreme
events etc..
Footprint
Evolution 2005-2008:
The Asian
Footprint evolution 2005-2008 is recorded by WWF in its two reports: WWF Living
Planet 2010 and WWF LPR 2012.
Asian
Pacific footprint on this 3 years period (Figure 5) increased by 5,7% which is more
than twice the Planet footprint increase during the same period. Asia Pacific
needs more Fishing ground (almost doubling), Forest land produce or service,
Built up land and Carbon regeneration; it needs less Crop land and Grazing land.
The diet modifications resulting from higher income conditions maybe explain this
profile with more fish and less cereal.
Figure 5 |
In the Asian
Pacific zone the biggest increases by countries (Figure 7) are in China,
Indonesia, India, Malaysia, South Korea, Myanmar, Thailand. Japan is the biggest
decrease (-16%) and some developed countries are slightly reducing: North
Korea, Australia, New Zealand.

Conclusion: Asian Pacific ecological
growing unbalance in 2008
When we
factor the unit footprint or biocapacity by the population we have the
footprint and biocapacity for the overall territory. By comparing both values
we derive each country unbalances as a percentage of its biocapacity or as an
absolute value (Figure 7).
Biocapacity
sources are mostly in
Australia, Indonesia, Mongolia, New Zealand, Myanmar, Papua New Guinea and Lao
PDR. Altogether we have only 288 mil gha sourced internally which is less than
10% of its total biocapacity.
Biocapacity
sinks are mostly in
China, India, Japan, South Korea, Thailand, Pakistan, Malaysia, Bangladesh,
Philippines, Singapore, Vietnam, North Korea, Sri Lanka. Altogether we have
3170 mil gha less the 288 mil gha sourced in the same zone which adds up to
2883 mil gha the global unbalance or 90% of biocapacity that needs to be
sourced outside the zone.
This
growing imbalance in the needs of biocapacity will become increasingly a factor
limiting the growth of the Asian Pacific zone and a source of tension within
and outside the area itself.
Moreover we
must remember that the ecological "global" footprint as proposed by WWF
is not very representative for the Asian Pacific zone which development is
based on a model of export to richer countries. Thus, the "real" footprint,
including addition of inputs of biocapacity in all various GDP components- not
only household consumption- are expected to further exacerbate this imbalance.
