State of the Environment reporting

A report on the Australian environment must be tabled in Parliament every five years

No current regulations regarding scope, content or process All reports so far written by independent committees

Purpose of SoE 2011

Provide relevant and useful information on environmental issues to the public and decision-makers...

… to raise awareness and support more informed environmental management decisions …

… leading to more sustainable use and effective conservation of environmental assets.

State of the Environment 2011 Committee

ChairTom Hatton (Director, CSIRO Water for a Healthy Country)MembersSteven Cork (research ecologist and futurist) Peter Harper (Deputy Australian Statistician) Rob Joy (School of Global Studies, Social Science & Planning, RMIT) Peter Kanowski (Fenner School of Environment & Society, ANU) Richard Mackay (heritage specialist, Godden Mackay Logan) Neil McKenzie (Chief, CSIRO Land and Water) Trevor Ward (marine and fisheries ecologist)Barbara Wienecke – ex officio (Australian Antarctic Division, DSEWPaC)

What’s new in 2011?

Improved relevance to decision makers

More detailed information

Discussion of the major drivers of change

Wide range of credible resources used in the analyses

Report-card style assessments of condition, pressures and management effectiveness

Discussions of current resilience and future risks

Outlooks

Quality and credibility Independence – written by an independent committee with

relevant expertise, tasked with providing ‘accurate, robust and meaningful environmental reporting and identification of policy issues, but not for any particular policy position’

Authors sought best available evidence from credible sources

Extensive consultation

Workshops to determine consensus in expert opinion where evidence low

Transparency about quality of evidence and level of consensus

Peer reviewed (47+ reviewers of chapters and supplementary materials)

conclusions

for each

What is the general state of the environment? Much of Australia is in good condition or improving

Wind erosion has decreased

Some major threats to vegetation cover are lessening

Water consumption has fallen considerably in recent years

Many urban air pollutants are on the decline

Use of public transport is on the rise

Other parts are in poor condition or deteriorating The East Antarctic Ice Sheet is losing billions of tonnes of ice a year

Soil acidification and pests and weeds are affecting large areas of the continent

Our natural and cultural heritage continues to be threatened

Drivers of environmental change

The principal drivers of pressures on Australia’s environment—and its future condition—are climate variability and change, population growth and economic growth

It is likely that we are already seeing the effects of climate change in Australia

The Australian economy is projected to grow by 2.7% per year until 2050

Under the base scenario, Australia’s population of 22.2 million people in 2010 is projected to grow to 35.9 million by 2050

We have opportunities to decouple population and economic growth from pressure on our environment

Persistent pressures on our environment Past decisions and practices have left ongoing impacts on

our environment Introduction of feral animals and weeds Land clearing Pollution Unsustainable water resource management Intense harvest of fish stocks Lack of integrated and supported management

Our changing climate, and growing population and economy, are now confronting us with new challenges

Attributes, values, complexities

Economic importance of the marine environment

Oil and gas – estimated at around $22 billion in 2007-08

Fisheries and aquaculture - $2.2 billion in 2008-09, mainstay of Australia's renewable marine resources

Recreational and subsistencefishing – marine tourism and recreation, including fishing estimated to contribute $18.7 billion in 2007-08 (no data for subsistencefishing)

Key findings The overall condition of the Australian marine environment is

good Areas near the coast are suffering There are significant existing impacts on the oceans caused by

human activities An extended continental shelf has been granted The ocean climate is changing and we need to prepare to adapt Our understanding of major aspects of our unique biodiversity is

limited The lack of a nationally integrated approach inhibits effective

marine management

Effectiveness of marine management - progress

Ecosystem-based fisheries management introduced

A number of marine species listed under EPBC Act

Threat abatement plans developed

New major programs funded

Marine protected areas declared

Marine bioregional plans being developed

Effectiveness of marine management – issues

Poor coordination within and between jurisdictions

Regional objectives for strategic marine planning and

management lacking

Federal leadership limited

Integrated national system lacking

No national system for assessment and

monitoring against national objectives

Effectiveness of marine management Coastal urban development

Understanding: Good understanding of types and sources of pollution – effective, improving

Planning: strong regulatory measures being developed and applied – effective, stable

Inputs: resources for planning and management at all levels of government – effective, stable

Processes: incremental development prevails, national synthesis and integration lacking – partially effective, stable

Outputs: no agreed management system, low impact solutions – partially effective, improving

Outcomes: ongoing development, pollution and impacts on habitats – partially effective, stable

Effectiveness of marine management Port facilities

Understanding: management issues and impacts well known – very effective, improving

Planning: advanced planning and approval systems – effective, improving

Inputs: limited resources to avoid impacts hindered by cost factors and operational requirements – effective, stable

Processes: localised management of issues, little management of cumulative impacts – effective, stable

Outputs: lacking sound integrated management, generic rule-based systems implemented – partially effective, improving

Outcomes: development driven by operational requirements, impacts on species and habitats – partially effective, improving

Effectiveness of marine management Oil and gas exploration and production

Understanding: impacts well understood – effective, improving Planning: regional environmental planning and assessment

framework lacking – ineffective, stable Inputs: substantial resources applied to impact issues – effective,

stable Processes: site approval based on economic requirements, limited

cumulative impact assessment – partially effective, stable Outputs: strong regulatory regime at site level, lacking onsite

compliance systems – effective, improving Outcomes: increasing impact on marine mammals, risk of accidents

and oil spills – partially effective, stable

Resilience and management outcome

Serial depletion Depleted stocks may not be resilient Fishdowns likely to have left Australia’s oceans less resilient

Current and emerging risks

Current and emerging risks – key risks Almost certain to occur + catastrophic consequences

Ocean warming Ocean acidification

Almost certain to occur + major consequences Port development/coastal urban development Fishing Marine debris Sea level rise Extreme or severe events Catchment-sourced pollution Algal blooms Ocean current changes

Climate change impacts on Australia’s oceans

Marine climate change in Australia 2009 report card concluded: Australian ocean temperatures have warmed – SW and SE waters

warming fastest

East Australian Current has strengthened – likely to strengthen by another 20% by 2100

Marine biodiversity in SE changing – response to increasing temperatures & stronger EAC

Growth rates of massive corals on Great Barrier Reef declined by 10% - likely due to ocean acidification & thermal stress

Outlook for the future Uncertain

Most aspects are currently not in decline Assets and values that are in poor condition are not recovering But – our knowledge base is very limited; few long term time series;

limited understanding of the stress-response relationships = limited predictability

No national time series for the condition of the major environmental assets/values

Looming threats Changing global climate Port development/coastal urban development Oil and gas exploration Variable between regions

Intentions and impacts of SoE 2011...

Based on available information and expert opinion drawn from sources that are referenced in the marine chapter

Was designed to raise awareness and assist decision-makers

Highlights current issues that will require management responses to influence projected trends

Provides critical information, but can support change only if decision-makers consider and use it
