STATE OF THE ENVIRONMENT REPORT 2006 NORTHERN SYDNEY REGIONAL ORGANISATION OF COUNCILS STATE OF THE ENVIRONMENT REPORT 2005 / 2006 Northern Sydney Regional Organisation of Councils Comprising the Councils of Hornsby, Hunters Hill, Ku-ring-gai, Lane Cove, North Sydney, Ryde and Willoughby HORNSBY HUNTERS HILL KU-RING-GAI LANE COVE NORTH SYDNEY RYDE WILLOUGHBY Mayor Berman Mayor Hoopmann Mayor Ebbeck Mayor Longbottom Mayor McCaffery Mayor Petch Mayor Reilly Councillor Delegate Councillor Delegate Councillor Delegate Councillor Delegate Councillor Delegate Councillor Delegate Councillor Delegate Felicity Findlay Ross Sheerin Elaine Malicki Rod Tudge Nick Ritten Edna Wilde Terry Fogarty STATE OF THE ENVIRONMENT REPORT 2006 PRESIDENt’S MESSAGE It has now been twelve months since the seven councils (Hornsby Shire, Hunter’s Hill, Ku-ring-gai, North Sydney, Lane Cove, City of Ryde, and Willoughby City) which comprise NSROC released the first regional State of the Environment (SoE) report for the northern Sydney Region. The first regional SoE was very well received by both the community and environmental professionals and encouraged the NSROC councils to continue with producing a regional report. This year we have provided a great deal of supplementary material in addition to building on the data sets and narrative contained within the first report. The intervening period between the reports has been marked by increasing community concern over water shortages, global warming, population impacts and transport issues. The NSROC councils have been working diligently with their communities and the state government to try and address the challenges these issues present in a cohesive and consultative way. A number of the councils have initiated innovative management strategies and projects, and there is also an ever increasing focus on sustainability. While all the councils continue to run strong bush care and stream remediation programmes, the health of our bushland and waterways remains a strong concern. Our data demonstrates that a number of our creeks are under significant pressure from development and disturbance and will require careful management into the future to ensure they remain viable ecosystems. It was with a great sense of relief that I learnt the state government has shelved its controversial plans to build a large-scale desalination facility in southern Sydney. While the supply of drinking water is a fundamental necessity for Sydney, all spheres of Government must take a leadership role in identifying sustainable and appropriate environmental solutions to the problems we face. The proposed desalination plant sent exactly the wrong message to our communities; instead of advocating re-use, recycling and an overall reduction in potable water use, it instead favoured an incredibly energy intensive process to supply what only amounted to a small portion of Sydney’s total water need. While the drinking water crisis has been temporarily averted due to other measures being implemented, we must all remain vigilant to ensure that short term measures are not employed by governments which do not look at the bigger environmental picture. The federal government has so far refused to sign the Kyoto Protocol which would lock Australia into a commitment to reduce greenhouse gas emissions. The issue of climate change and the impacts that are being experienced right now are compelling individuals and communities around the world to take action. The NSROC councils are doing their bit and all of them are reviewing and reducing their own energy consumption as well as working with, and educating, their communities. Like water, energy is going to be one of the biggest challenges Australia has to face over the coming decades. We must act now to ensure that the beautiful environment of the northern Sydney region is not irretrievably damaged due to a stubborn reluctance by politicians, industry or individuals to recognise the issues and adapt their practices and policies appropriately. In many areas the northern Sydney councils are on the cutting edge of environmental innovation and with our strong environmental heritage and relative prosperity we have the opportunity to show leadership both within the region and beyond. Again I commend this regional SoE report to you as the next step in ensuring that the environment of our region receives the strategic, collusive and sustainable management approach it so richly deserves.
