Can preserving humble seagrass help protect us from the extremes of human-induced climate change?
The oceans have long been recognised by science as vital for capturing carbon and renewing the atmospheric balance that preserves life on earth. While vast amounts carbon are captured by phytoplankton, less well known has been the role played by seagrasses in storing carbon, cleansing the air and providing essential habitat for marine life.
Based on latest UTS marine research, this public lecture reveals the essential place of seagrasses in global ecology, the growing threats to its continued viability and the work that is being done to rehabilitate the areas of seagrass habitat already lost.
Professor Bill Gladstone
Marine biologist Bill Gladstone applies scientific understanding to solve problems in marine conservation and environmental management. His interests lie in assessing conservation values in marine ecosystems, the selection and management of marine parks, and community participation in marine conservation. He has worked throughout NSW, the Great Barrier Reef, Torres Strait, the Coral Triangle, and the Middle East.
Dr Peter Macreadie
Marine ecologist Peter Macreadie is a UTS Chancellor’s Postdoctoral Research Fellow. His research cover a wide range of systems; from deep-sea reefs to intertidal oyster reefs. Peter’s current research focuses on seagrasses to better understand how their resilience to climate change can be improved, and how can we capitalise on their ability to capture and store atmospheric carbon.
Professor Peter Ralph
Peter Ralph has been working with seagrasses since the early 90’s, when he pioneered the use of optical methods of measuring photosynthesis to examine the impact of pollution on seagrass health. More recently, he is developing new tools to assess the ability of an entire seagrass meadow to fix carbon. This work is now part of an international research agenda lead by the International Union for Conservation of Nature (IUCN) to demonstrate the importance of seagrasses in the global carbon cycle.

C5.07: Blue Carbon: Current status of Australian estimates and future model p...Blue Planet Symposium
Blue carbon is becoming widely recognised as a critical component of all national carbon accounting schemes. Australia has invested heavily in collating existing estimates of blue carbon stocks and is currently targeting important yet poorly represented habitats around its extensive coastline. Much of this effort is linked with the CSIRO-funded Coastal Carbon Cluster. This 3-year program has developed and validated many approaches to blue carbon estimation and is now able to showcase best-practice methods. The activities of the Cluster have been used as a model for international efforts to develop global estimates, as well as national blue carbon inventories via the International Blue Carbon Scientific Working Group. Finally, static estimates of carbon can only describe the current carbon stock at a specific location; models can extrapolate these relationships into unsampled regions, as well as estimate carbon stock into the future given changes to climate as well as alterations to the geochemistry/hydrodynamics of a specific habitat.
In this presentation by Nyoman N. Suryadiputra from the Wetlands International Indonesia Programme given during the Forests Asia summmit in the discussion forum "Managing mangrove forests for climate change mitigation and adaptation benefits" the following questions will be answered:
What is silvo-fishery ?
Can silvo-fishery practices gain carbon?
How is the results ? Any lessons can be learned ?
How Aquaculture Certification related to mangroves?
Phil Colarusso, Boston Office of the EPA
Wetlands and coastal waters are exceptionally effective at storing carbon as well as performing many other ecosystem functions. Phil Colarusso tells us how cities and the global climate benefit from offshore seagrass beds, one of the richest of ecological resources and carbon sinks and part of the Boston area's native habitat. Eelgrass survival is entirely dependent on effective management of water resources for human use, especially intact healthy wetlands and efficient sewage disposal.

C5.01: Ocean acidification and seawater carbon chemistry of the Great Barrier...Blue Planet Symposium
Ocean acidification is considered a major threat to the health and sustainability of tropical reef ecosystems. Observations of carbonate chemistry have been made over a range of scales from reefs to ocean hydrographic sections in the Southwest Pacific and Great Barrier Reef (GBR) in order to establish baseline conditions for tracking ocean acidification change. A major component of the research has been monthly sampling of shelf waters along the entire length of the GBR using a ship of opportunity, RTM Wakmatha. The observations provide measures of the vital signs of the reef health and growing conditions. The results show that seawater carbonate chemistry is strongly influenced by the flow of Coral Sea waters onto the GBR shelf, with localised modification of the water chemistry by calcification/dissolution and production/respiration in the many reefs and coastal regions of the GBR. The shelf-offshore changes are similar in size to ocean acidification changes predicted over the next few decades due to ocean CO2 uptake. The changes in carbonate chemistry indicate that many reefs of the GBR may already be exposed to marginal growing conditions with respect to seawater carbonate chemistry. However, the results are also consistent with a net calcification signal for the GBR, with no evidence of large-scale net dissolution that may occur under ocean acidification. The research is a basis for developing an integrated modelling and sustained observational approach for 1) determining how the GBR is responding to ocean acidification and other stresses (e.g. tipping from conditions of net growth to net loss of reef), 2) diagnosing the complex feedback mechanisms on the GBR that alter water chemistry and influence the resilience of reefs to ocean acidification, and 3) delivering tools and evidence for informed decision making on responses to ocean acidification.

UTSpeaks: A medicated nation
Has Australia lost its way in a pharmaceutical love affair?
Professor Charlie Benrimoj and Associate Professor Mary Bebawy from the University of Technology, Sydney present at this public lecture on prescription medication held on 13 September, 2011.
How many pills will you take today? Do you really need them? What good (and bad) will they do you?
For many of us prescription medications mean the difference between good and ill-health. There’s no denying their important place in fostering well-being for many. But is it time to reflect on the complex forces at work when managing disease and medications and how this impacts you the consumer?
Featuring leading UTS researchers in pharmacy and using example case studies, this public lecture takes a critical look at how medications are prescribed and consumed in Australia. It considers whether we are getting value for money, the ideal health outcomes we hope for and whether new approaches to the responsible use and explanation of medications could be adopted.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

21. Climate Change: How are we doing?
US Dept of Energy report (Nov 2011):
● “Biggest jump ever in global warming gases”
● CO2 output in 2010 was 6% higher (512
million tonnes) than in 2009
● Greenhouse gas emissions were higher
than the worst-case scenario outlined by
climate experts (the IPCC)
22. Fighting climate change using nature
● Reducing greenhouse gas emissions is necessary, but
how do we get rid of all the emissions already floating
around the atmosphere?
● Biosequestration: nature‟s
way of capturing and storing
carbon in sediments
● It‟s the same process that
created fossil fuels in the first istockphoto
place!
23. Carbon Farming
1. Reducing greenhouse gas
emissions
1. Capturing and storing carbon in
vegetation and soils (creating
„carbon sinks‟) RDAMR
Terrestrial only. Not aquatic.

27. Seagrasses are long-term sinks
● Terrestrial forests typically store carbon for
decades, whereas seagrasses store
carbon for millennia!
● Carbon rich deposits can be >10-m thick
● Unlike terrestrial soils, the sediment in
seagrass meadows do not become
saturated with carbon
● Why? Because the sediments accrete
vertically in response to rising sea levels.
28. Carbon farming: too good to be true?
‘Leakage’ is a big concern
● Increasing forest productivity
can trigger CO2 release from
soils
● Increasing CO2 levels in
terrestrial soils can stimulate
production of other
greenhouse gases

29. Do seagrass meadows leak carbon?
Could 1000s of years of
ancient carbon leak out
into the atmosphere if
seagrass meadows are
disturbed?
Likely mechanism: loss
of seagrass meadows
(i.e. the „top layer‟)
exposes buried carbon
to the forces of nature

34. What impact have humans had on coastal carbon sinks?
Industrial developments:
• Tanneries
• Sewerage farms
• Breweries
• Quarries Algernon Talmadge
R.A.
• Oil refineries
• Sand mining
• Port construction
Consequences:
• Loss of seagrass, mangroves,
and saltmarsh
• Increases in algae

37. Take home messages so far
● Highly efficient carbon biosequestration
● Large carbon storage in seagrass sediment
● Carbon stays in the sediment for a long time
● Degradation results in substantial carbon emissions and
loss of biosequestration
38. How to protect seagrass carbon?
● What is Blue Carbon?
● What don't we know?
– Can a degraded meadow release it stored carbon?
● How do currently protect plant-based carbon?
– How can we protect seagrass carbon?
● What is happening internationally?
● What can you do locally?
39. Is there carbon leakage ????
Assume it “comes out quicker than it goes in”
Assume the loss of seagrass leads to substantial
CO2 emissions and loss of highly efficient
biosequestration
40. Drained marshes emit CO2
● Sacramento Delta
– 1,800 km2 of wetlands (not seagrass)
wikipedia
● has released 1 GtCO2 (1,000,000,000 tons of CO2)
• 50% of tree biomass in Californian forests
• 1.5% of California total GHG emissions
● C sequestered over 5,000 years, released in 100 years
41. Do degraded seagrasses emit CO2?
● Yes
● Does it contribute to the atmospheric CO2?
– we don‟t know,
– If they do, then seagrasses matter, because their
loss will further enhance climate change.
42. How to protect seagrass carbon?
● create incentives for coastal conservation and restoration
activities
● create disincentives to damage coastal ecosystems
43. Better to conserve than restore
● Conserve = Dual benefit
● More efficient to sustainably manage than to allow loss and
then attempt to re-colonise
● Restoration may be necessary
wikipedia wikipedia
44. Past methods of protecting carbon
● Kyoto Protocol (1997)
– Countries agreed to limit GHG emissions
• “flexible mechanisms” to meet these limits
• Annual inventory
• Doesn‟t include coastal wetlands
● Copenhagen Accord (2009)
– Ratify REDD
● Cancun Agreement (2010)
– Ratify REDD+ which includes mangroves (not seagrass)
– Blue Carbon recognised
45. International carbon credits
● finance to encourage sustainable management
– Norway-Indonesia
● Australia-Indonesia Carbon Partnership
● Australia could buy Indonesian “ecosystem restoration concessions”
– Australian Clean Energy Scheme
wikipedia
● How can seagrass be included in a carbon accounting scheme?
46. Seagrass carbon accounting
● Does seagrass loss actually leads to increased atmospheric CO2?
● IPCC needs to recognise sediment-based C storage
– above-ground biomass is easy to count and satellites can monitor
● Develop a seagrass carbon budget protocol:
– quantification
– verification of stock over time
– how long does the carbon remain within the financial unit
– estimate of risk of loosing stock (insurance)
● Engage with a carbon trading market
– voluntary market already operational for mangrove (Blue Carbon)
47. How is IUCN helping this happen?
● creating political awareness
● helping NGO generate public awareness
● drafting policy for IPCC, such as REDD+
● establishing a international research and policy agenda
48.
49. What can you do?
● Ask questions about removal of local seagrasses
● Ask questions if you see seagrass dying
● Engage with community monitoring of seagrasses
● Support seagrass restoration programs
● Increase public/political awareness of Blue Carbon

Seagrasses are marine flowering plants that occur along all coastlines of the world ex Antarctica, which gives them a wider distribution than mangroves or coral reefs.As shown by this photo seagrasses consist of the above ground leaves and stems, and below ground there is an extensive system of roots and rhizomes that play an important part in shaping the overall biodiversity and ecological functions of seagrass.Australia has the greatest number of seagrass species, and the greatest area, making it a global hotspot for seagrass biodiversity, and vital for the long term conservation of these organisms.Estimates of the global area of seagrass vary widely from almost 200,000 to 600,000 sq km.
Accurate estimates of seagrass area are critical for documenting the changes that are occurring in response to human activities and natural dynamics, and this is calculated by a variety of techniques.Where this technology is available, detailed understanding of seagrasses is possible, such as the example here of the changes in the extent of a seagrass meadow in Rose Bay.Uncertainties in the total area of seagrass arise from various constraints, and these are particularly relevant in developing countries where some of the stressors are greatest.It becomes a further issue when considering the potential importance of seagrass in carbon biosequestration, and my colleagues will discuss this further.
Seagrass meadows have a greater number of species and more individuals than unvegetated areas in the same ecosystem.The value of seagrass for biodiversity arises from the diversity of ecological niches available in the leaves, the roots, rhizome, the sediment and the water overlaying the seagrassThe value of seagrasses for biodiversity is highlighted by their importance for the more charismatic species, and less well documented is their importance for threatened and endangered species, with approx 60 species dependent on seagrass
Seagrasses are important for commercial, recreational and artisanal fisheries. This value arises from the use of seagrass meadows by the juvenile stages of many species, who use seagrass meadows as nurseries because of the shelter they provide from predators and the food available. Less well quantified is the value of seagrass-based artisanal fisheries, where the links between seagrass health and socio-economics are likely to be strong.

Article 3 states that the Parties will include the "net changes in greenhouse gas emissions from sources and removals by sinks resulting from direct human-induced land use change and forestry activities, limited to afforestation, reforestation, and deforestation since 1990, measured as verifiable changes in stocks in each commitment period" (Kyoto Protocol, 1997). These sinks will be added to or subtracted from Parties' gross emissions when assessing changes over 2008-2012. This Article has given rise to the popular, informal term the "Kyoto Forest."The Protocol does not include sequestration in agricultural soils or wetlands. However, article 3.4 specifies that subsequent meetings would determine rules and guidelines for including additional human-induced activities in the "agricultural soil" and land-use change and forestry categories (Kyoto Protocol 1997). Should agricultural soils become recognized under the Protocol, this step could strengthen the case for including wetlands. "The agricultural lands of Canada include localized wetlands. Those wetlands may also be included if agricultural soils sinks are included in the Protocol" (National Sinks Table, 1998).
