EASTSIDE RADIO (89.7 fm) - www.eastsidefm.org
GREEN CITY (Tuesday, 5.30 – 6 pm – hosted by Joanne Bacic)

Week 1 Tuesday, 22 June, 2004: Strategic Planning Overview

The introduction to the series on Botany Bay was an interview by Joanne Bacic with Susan Taljaard, Environmental Scientist, CSIR, Stellenbosch, who gave a seminar on 18 June, "Research and Management of Estuaries in South Africa" at UNSW Water Research Laboratory (www.wrl.unsw.edu.au). The key message was involving stakeholders in the sustainable management of resources.

The significance of Botany Bay and the complex and conflicting values associated with the bay were outlined by John Black, Director of the UNSW Botany Bay Studies Unit.

The future of Botany Bay is linked to two strategic planning documents that the community is encouraged to read and to comment on the New South Wales Department of Infrastructure Planning and Natural Resources (www.dipnr.nsw.gov.au).

The “Metropolitan Strategy” is being advanced during 2004. The Minister’s Direction Paper is available at www.metrostrategy.nsw.gov.au and the website provides an opportunity for people to register interest in obtaining regular updates. John Black attended the Sydney Futures Forum on May 18 and 19 noting the importance of “place management” and inputs from the grass roots level in informing the development of strategies.

The community would be especially interested in the release by the Minister on 1 June, 2004, of the Discussion Paper on the Botany Bay Draft Strategy inviting public comment over a three-month period. A Sydney Metropolitan Catchment Management Authority is proposed. A range of stakeholders were represented on the Botany Bay Strategy Advisory Committee, including UNSW (Professor John Benzie, former Director Botany Bay Studies Unit) and the University of Sydney (Professor Tony Underwood). The advisory committee endorsed the importance of independent scientific research into Botany Bay that would inform decision makers, and the importance of communicating information and research findings to the wider community.

The Botany Bay Studies Unit has been involved in research scoping exercises, and on 28 February 2004 convened a workshop at UNSW to identify research topics and research priorities. About 120 representatives from government, NGOs, industry, the community and research institutions were involved. The program may be found at www.bbsu.unsw.edu.au.

Research recommendations are presented in the Botany Bay Moving Forward report also available on the same website.

The topics include the hydrodynamics of the bay, storm water and waste water, ground water and pollutants, ecology and habitats, foreshores, airport, port and transport and environmental history and industrial legacy. These topics will form the basis of later programs.

One research area identified in the workshop, and mentioned on the program, was to be informed of overseas and Australian models of governance and management of urbanised bays and estuaries. The Botany Bay Studies Unit is advancing this recommendation with a public lecture from an expert panel on Tuesday evening, 19 July, 2005 (next year) in the Scientia Building, UNSW. The organising panel includes Jim Colman (SSROC), Nancy Hillier (Botany Historical Society) and Paul Beavis (doctoral candidate, UNSW). Information will be posted on this website next year.

Week 2 covers transport – the value of research, sustainable transport, port traffic, and aircraft noise and community health and well-being. Listeners are invited to contact Joanne Bacic with other topics they may wish to hear about.

Week 2 Tuesday, 29 June, 2004: Transport

The purpose of these notes is to encourage community discussion and debate on the NSW Department of Infrastructure, Planning and Natural Resources Discussion Paper Towards a Strategy for Botany Bay (www.dipnr.nsw.gov.au/botanybay). In the radio program, transport issues covered were passenger transport and sustainability, Port Botany and freight transport, and aircraft noise and community impacts.

A major thrust of the Discussion Paper Towards a Strategy for Botany Bay is improving management, establishing management goals, and initiatives to improve the management process. For this reason, there is limited specific mention of transport plans other than the important consideration of reducing and managing impacts of transport – the demand for transport, the port and freight traffic and the relationship to metropolitan planning (see broadcast notes, Week 1).

Policies to make transport more sustainable are justified at a number of levels. In Australia, the transport sector contributes about 14 per cent of net greenhouse gas emissions – making Australia the 3rd highest per capita producer of greenhouse gases. Motor vehicles contribute about 70 per cent of the total, and the number of motor vehicles in Australia is likely to grow substantially over the next 10 years. In metropolitan Sydney, air quality has been recognised as a major issue for 10 years and the NSW Government has set strategic targets to reduce the vehicle-kilometres of travel (VKT) by motor vehicles in the future. Progress towards a more “sustainable” urban transport sector can be informed by research into suitable performance indicators.

Readers interested in pursuing this topic further are encouraged to search appropriate websites, of which the following may prove a useful start.

In outline, a more sustainable future city will reduce the problems of low-density sprawling suburbs that are car-dependant and will provide a fair access to land-use activities, provide better public transport with higher usage of “green transport” modes such as walking, cycling and public transport. Policies of urban consolidation have implications for residents around Botany Bay with future growth of 77 000 new residents expected by 2026 and that additional pressure on transport infrastructure and services.

Metropolitan growth also entails an expansion of the freight task. The numbers of container movements into and out of Sydney are expected to triple over the next 20 years, and if plans for an expansion of Port Botany go ahead there will be issues of land-side transport access both road and rail to resolve. Research can inform the decision making process, as recognised in the recommendations of the Botany Bay Moving Forward Workshop, by examining a range of options to accommodate maritime transport in terms of economic, social and environmental impacts, and by obtaining a better understanding of the urban collection and distribution of the freight packed in containers. The Botany Bay Studies Unit has been commissioned to undertake a detailed research scoping study of urban freight and Port Botany. In addition, Paul Beavis has been awarded a CSIRO Endowment Fund to organise and conduct a workshop of stakeholders including community representatives on freight futures, planned for later in 2005. (BBSU RESEARCH PROJECTS)

Also associated with a larger metropolitan region and tourist promotion is a demand to accommodate passengers and freight at Sydney Airport. More planes mean an increase in aircraft noise in suburbs surrounding the airport. Research conducted at UNSW has developed a new noise metric to assess the impact of aircraft noise on the community that takes into account the background environmental noise (BBSU RESEARCH REPORT 1)

Research in progress is investigating if there are relationships between the measured noise and resident’s reported assessment of their health and well being. The community can assist greatly in research by responding to requests by researchers to participate in social surveys. In this study (jointly conducted by the School of Public Health and Community Medicine, Faculty of Medicine, and the School of Civil Engineering, Faculty of Engineering), we thank those residents of noise affected and control areas for return our questionnaire (based on a validated instrument to assess health status developed at Harvard University).

The Botany Bay Studies Unit has been approached by a group from Kurnell to respond to ideas for a novel scheme for noise mitigation in localities outside of the approved Federal Government scheme for the noise reduction in residential dwellings. The proposal is awaiting a response for funding.

Week 3 Tuesday, 5 July, 2004: Contaminants in Botany Bay

The opening segment to the program was a recorded interview with a representative of a community group highlighted issues on Botany Bay, including port proposals. Transport was the topic of week 2, including discussions on sustainability. Sydney University are hosting a one-day, free symposium on “Sustainable Transport in Sustainable Cities” at the Everest Theatre, Seymore Centre on Thursday, 22 July 2004.

The problem is that “cocktail” of pollutants enter Botany Bay from various sources such as run-off into rivers and creeks, storm water, groundwater and leaks of sewage. There are multiple sources of contaminants that become diluted in the bay and dispersed making monitoring of the whole bay a complex scientific matter to resolve. It is therefore difficult to establish environmental stress and we lack a base level reference against which progress towards sustainability (or otherwise) may be assessed.

Fortunately, Alberto Albani has established a scientific method to study the permanent record of water quality that is found on the sea bed. The distribution of organisms and sedimentary geology reflect quality of water masses. Foraminifera - a marine protozoa that secrets a shell (0.1 to 2mm in size) - are ideal organisms for measuring long-term changes. They are in high abundance, making detection possible, and they are sensitive to salinity, temperature, water depth and food sources. Sampling from the bay and laboratory analysis provides valuable information. For further details go to BBSU RESEARCH REPORT 2

The Botany Bay Studies Unit is proposing research to establish the base line for monitoring by identifying the assemblages of Foraminifera in the Bay, and investigating the relationship between these populations and environmental parameters.

Previous research has established that the high contaminant loads such as heavy metals are at the mouth of rivers (see, for example, the research published by Gavin Birch at Sydney University, “The Dominance of Point-source in Heavy Metal Distribution in Sediments of a Major Sydney Estuary”’ in Journal of Environmental Geology, Volume 28, Number 1).

Field research at UNSW by Dr Emma Johnston at Caltex Pier studies the concentrations of heavy metals that are at background levels because this area is flushed by oceanic water. Her research area is how pollution may facilitate the invasion of marine communities where the Caltex Pier as a non-polluted site at which to run experiments. Earlier research has established the effects of a single pulse copper pollution event on established marine assemblages in Port Philip Bay (“Direct and Indirect Effects of Repeated Pollution Events on Marine Hard-Substrate Assemblages” in Ecological Applications, Volume 12, Number 4).

One of the agreed values for Botany Bay (discussed in Week 1) is the recreational importance of the bay, including recreational fishing. Therefore an important question for the community is whether toxic heavy metals get into fish. (It is an important personal question as John Black had promised to eat edible fish caught in Botany Bay by his Tutor at UNSW, Toshihito Kato - to whom he gave as a present a fish lure in thanks for excellent teaching in Japanese Communication 2A. Iain Suthers at UNSW is a scientist with extensive research into fish that informs the following observations. There is no scientific evidence that the toxic levels in fish in Botany Bay pose any problems to human health if eaten. There is tidal flushing of the bay. Fish migrate in and out of the bay. Some elements absorbed by fish occur naturally whereas others are from contaminants. Elements tend to be stored in parts of the fish that we do not eat.

None of the above suggests we should be complacent about the issue of contaminants in Botany Bay. We all should take responsibility to prevent the generation of contaminants and making sure nothing harmful enters the bay. The Orica site is a major concern and so next week’s program will focus more on where the contaminants have come from. It will discuss ground water and remediation technologies available and how research and development might inform decision-making processes.
