Jakarta, May 11, 2009 (ANTARA)
- As more than 120 nations gather in Manado, Indonesia for the World
Oceans Conference the issue of climate change should be high on their minds.
The world's oceans and seas are now understood to be the biggest sink of
greenhouse gases from the burning of fossil fuels.
Indeed experts now estimate that up to 40 per cent of the C02 entering the
atmosphere is being cycled through the marine environment playing a crucial
role in moderating climate change.
But experts are warning that the marine realm cannot continue to soak up
man-made pollution forever without consequences.
Many marine living creatures from corals and crabs to plankton at the base of
the food chain need seawater that is alkaki to build their skeletons.
The average pH of water at the ocean's surface has now fallen from 8.16 to 8.05
since the beginning of the Industrial Revolution - small falls, but with
potentially huge impacts if this continues.
Faced with this
rapidly emerging science, the question is then what to do.
Firstly, governments must affirm their determination to 'Seal the Deal' in
Copenhagen at the UN climate convention meeting in order to begin steering the
world onto a low carbon course.
Secondly, we have to improve the health of our oceans.
They have to be as fit and resilient as possible, so that they can cope with
the climate change burden-- so they can continue to provide us with food and
the myriad of other economically-important services.
This means governments have to urgently address the multiple challenges
weakening our seas, from land based pollution and discharges from ships up to
overexploitation of the globe's vital fisheries, fueled in large part by
perverse and wasteful subsidies totaling up to $35 billion a year.
Currently somewhere around 12 per cent of the land is held in protected areas,
but less one per cent of the marine environment enjoys such status so this
needs to change, and to change fast too.
Meanwhile
pollution levels, 80 per cent of which come from factories, cities and farms on
the land, also need to be cut.
More than 60 countries have now developed national action plans under the
voluntary UNEP initiative called the Global Programme of Action (GPA) for the
Protection of the Marine Environment from Land-Based Sources and we have 18
Regional Seas agreements now operating across the globe.
It is a start, but to date the magnitude of the global response still fails to
reflect the challenge as evidenced by the growing number of 'dead zones'
de-oxygenated areas of sea linked with fertilizer and sewage-run alongside
emissions from cars and shipping that now number 200.
Ways of boosting the health of the oceans should be a key issue in Manado in
recognition of the importance of our seas in buying humanity much needed
breathing space with respect to climate change.
Indeed perhaps it should now be pay back time. Firstly, investments in
adaptation should not end at the shoreline--investing in the rehabilitation,
rejuvenation and resilience of coastal ecosystems, from mangroves to coral
reefs and wetlands, can generate significant returns in respect to
climate-proofing economies.
These include protecting vulnerable communities against storms surges and sea
level rise while also helping to soak up greenhouse gas emissions; filter
pollution and improve the health of fisheries.
And perhaps, just
over the horizon, there is an even bigger prize'a way to make the oceans part
of the carbon market options.
Consider the history of forests. The suggestion that developing countries
should be paid for not cutting down trees was dismissed over ten years ago as
flawed.
But in Copenhagen there is a good chance that part of the deal will include
forest payments to tropical nations including Indonesia. Eventually other
land-based ecosystems may also be considered from peat lands to soils.
The oceans play a vast role in countering climate change - they are our 'blue'
forests.
Rewarding countries that sustainably manage them to boost their climate
combating role and productivity would seem well worth exploring--Manado is an
opportunity and the forum to float such ideas.
Time to combat change is bubbling away fast. We need all hands on deck to turn
this climate ship around from investments in energy savings and low, and zero
carbon technologies to markets that promote healthy ecosystems' forests for
sure and perhaps our oceans and our seas too.
