Bucket dredging to mine and extract gold and tin from rivers is a global industry that has had a range of negative effects on physical environments. These include the destruction of riparian soil profiles and structures, artificial channel straightening and loss of in-stream biodiversity. In this paper we evaluate the immediate effects and long-term consequences of bucket dredging on rivers in Victoria and New South Wales during the period 1900–1950. High quality historical sources on dredge mining are integrated with geospatial datasets, aerial imagery and geomorphological data to analyse the scale of the dredging industry, evidence for disturbance to river channels and floodplains and current land use in dredged areas. The study demonstrates that the environmental impact of dredging was altered but not reduced by anti-pollution regulations intended to control dredging. An assessment of river condition 70–100 years after dredge mining ceased indicates that floodplains and river channels continue to show the effects of dredging, including bank erosion, sediment slugs, compromised habitat and reduced agricultural productivity. These findings have significant implications for river and floodplain management.

The concept of environmental auditing of point source pollution has been adapted to nonpoint source pollution in rural lands. Geographic Information Systems (GIS) and other information technologies provide an effective environmental management tool for characterising nonpoint source (NPS) pollution in a regional context and thereby can assist the environmental auditing process. Nonpoint source pollution problems of rural watersheds in Australia, particularly those in the state of New South Wales, and the role of the state's environment protection agency are outlined. A case study that applies an auditing methodology using GIS in a study area within the Lachlan River catchment is presented. The suitability of the approach for land condition evaluation and the review of land use controls for nonpoint source pollution is discussed.

Fifty years have passed since the first commercial inoculants were manufactured in Australia. Before 1953, various Government Agencies supplied mostly agar cultures with New South Wales Department of Agriculture issuing the first peat-based inoculants. There are no data to indicate the quality of these inoculants, but in the early commercial cultures rhizobia were often outnumbered by contaminants and field failures were widespread. A comprehensive system of quality control was developed from discussions between CSIRO and the University of Sydney. Succeeding quality control bodies have continued on the basis of the original scheme. It set inoculant standards, approved and supplied mother cultures to manufacturers annually, tested all batches of peat inoculants before sale and sampled inoculants at the point of sale. In this paper we describe the history of Australian legume inoculants, list the commercial firms and key people involved and the period during which they were active. We tabulate the strains involved, indicate the period of their use and highlight some of the problems encountered with them and with inoculant production. We indicate the personnel who have been particularly active in the quality control of inoculants, the funding bodies who have supported the work and stress the reliance of the control laboratories on the help of many agricultural scientists in Australia. An important part of the control scheme has been the implementing of standards without resort to legislation. This has depended on the cooperation of the manufacturers involved and has allowed flexibility in applying the standards.

Soil is a valuable natural resource. In the state of New South Wales, Australia, the governance of soil has evolved since Federation in 1901. Following rapid agricultural development, and in the face of widespread soil degradation, the establishment of the Soil Conservation Service marked a turning point in the management of soil. Throughout the 20th century, advances in knowledge were translated into evolving governance frameworks that were largely reactionary but saw progressive reforms such as water pollution legislation and case studies of catchment-scale land and vegetation management. In the 21st century, significant reforms have embedded sustainable use of agricultural soils within catchment- and landscape-scale legislative and institutional frameworks. What is clear, however, is that a multitude of governance strategies and models are utilised in NSW. No single governance model is applicable to all situations because it is necessary to combine elements of several different mechanisms or instruments to achieve the most desired outcomes. Where an industry, such as the sugar industry, has taken ownership of an issue such as acid sulfate soil management, self-regulation has proven to be extremely effective. In the case of co-managing agricultural soils with other landuses, such as mining, petroleum exploration and urban development, regulation, compliance and enforcement mechanisms have been preferred. Institutional arrangements in the form of independent commissioners have also played a role. At the landscape or total catchment level, it is clear that a mix of mechanisms is required. Fundamental, however, to the successful evolution of soil governance is strategic investment in soil research and development that informs the ongoing productive use of agricultural landscapes while preventing land degradation or adverse environmental effects.

ABSTRACT In South Australia, the newest Australian liquid hydrocarbon marine export terminal has been completed in record time. The terminal services domestic and export trade in crude oil, condensate and liquified petroleum gases while operating within a gulf which supports a major shellfish and scalefish industry, and a small but growing recreation market. The Terminal Operator has undertaken an integrated, rational, and cost-effective environmental protection strategy based on planning studies designed to ensure government and community approval for the facility. The study subject areas include: oil slick trajectory forecasting, ballast water diffuser outfall performance, prawn taint testing, coastal habitat sensitivity rating and mapping, oil spill response equipment selection and deployment strategies, equipment field trials, and industry-government consultative groups.

Olives (Olea europaea ssp. europaea), dispersed from 19th century orchards in the Adelaide area, have become established in remnant bushland as a major environmental weed. Recent expansion of the Australian olive industry has resulted in the widespread planting of olive orchards in South Australia, Victoria, New South Wales, Western Australia, Queensland and parts of Tasmania. This paper reviews the literature on the activity of vertebrate (principally avian) olive predators and their potential as vectors for spreading this plant into Australian remnant bushland. The effects of feralisation on the olive plant, which enhances its capacity for dispersal as a weed, place wider areas of south-eastern Australia at risk. A number of approaches for the control of olives as woody weeds are addressed. Proponents of new agricultural crops have moral and environmental obligations to assess the weed potential of these crops.

In the 20 years before the Second World War the frontier war dragged to a close in remote parts of north Australia with the 1926 Daly River massacre and the 1928 Coniston massacre. There was a rapid decline in the Aboriginal population, giving rise to the idea of the ‘dying race’ which had found policy expression in the State ‘Protection’ Acts. Aboriginal and Islander labour was exploited under scandalous rates of pay and conditions in the struggling north Australian beef industry and the pearling industry. In south east Australia, Aborigines endured repressive white control on government reserves and mission stations described by some historians as being little better than prison farms. A largely ineffectual Aboriginal political movement with a myriad of organisations, none of which had a pan-Aboriginal identity, struggled to make headway against white prejudice. Finally, in 1939, John McEwen's ‘assimilation policy’ was introduced and, though doomed to failure, it at least recognised that Aborigines had a place in Australia in the long term.

Urban drainage systems historically were developed on principles of hydraulic capacity for the transport of storm water to reduce the risk of flooding. However, with urbanization the percent of impervious surfaces increases dramatically resulting in increased flood volumes, peak discharge rates, velocities and duration, and a significant increase in pollutant loads. Storm water and urban runoff are the leading causes of the impairment of receiving waters and their beneficial uses in Australia and the United States today. Strict environmental and technology controls on wastewater treatment facilities and industry for more than three decades have ensured that these sources are less significant today as the cause of impairment of receiving waters. This paper compares the approach undertaken by the Environmental Protection Authority Victoria for the Melbourne metropolitan area with the approach implemented by the California Environmental Protection Agency for the Los Angeles area to control storm water pollution. Both these communities are largely similar in population size and the extent of urbanization. The authors present an analysis of the different approaches contrasting Australia with the USA, comment on their comparative success, and discuss the relevance of the two experiences for developed and developing nations in the context of environmental policy making to control storm water and urban runoff pollution.

The use of genetic information in conservation biology has become more widespread with genetic information more readily available for non-model organisms. It has also been recognized that genetic information from invasive species can inform their management and control. The red fox poses a significant threat to Australian native fauna and the agricultural industry. Despite this, there are few recently published studies investigating the population genetics of foxes in Australia. This study investigated the population genetics of 94 foxes across the Illawarra and Shoalhaven regions of New South Wales, Australia. Diversity Array sequencing technology was used to genotype a large number of single nucleotide polymorphisms (N = 33,375). Moderate genetic diversity and relatedness were observed across the foxes sampled. Low to moderate levels of inbreeding, high-levels of identity-by-state values, as well as high identity-by-descent values were also found. There was limited evidence for population genetic structure among the foxes across the landscape sampled, supporting the presence of a single population across the study area. This indicates that there may be no barriers hindering fox dispersal across the landscape.

This paper systematically summarizes the hierarchical cross-regional multi-directional linkage in terms of air pollution control models implemented in the Beijing-Tianjin-Hebei urban agglomeration, including the hierarchical linkage structure of national-urban agglomeration-city, the cross-regional linkage governance of multiple provinces and municipalities, the multi-directional linkage mechanism mainly involving industry access, energy structure, green transportation, cross-regional assistance, monitoring and warning, consultation, and accountability. The concentration data of six air pollutants were used to analyze spatiotemporal characteristics. The concentrations of SO2, NO2, PM10, PM2.5, CO decreased, and the concentration of O3 increased from 2014 to 2017; the air pollution control has achieved good effect. The concentration of O3 was the highest in summer and lowest in winter, while those of other pollutants were the highest in winter and lowest in summer. The high pollution ranges of O3 diffused from south to north, and those of other pollutants decreased significantly from north to south. Finally, we suggest strengthening the traceability and process research of heavy pollution, increasing the traceability and process research of O3 pollution, promoting the joint legislation of different regions in urban agglomeration, create innovative pollution discharge supervision mechanisms, in order to provide significant reference for the joint prevention and control of air pollution in urban agglomerations.

Bibliography: pages 134-147.Pollution control regulations directed at the land-based factories of the Southern African fish processing industry do not appear to promote the required level of investment in pollution control systems. Two self-administered mail-questionnaires comprising undisguised fixed-alternative and open-ended questions were constructed to survey the opinions and viewpoints of a census consisting of twenty-seven senior managers responsible for making pollution control investments in the demersal and pelagic sectors of the fish processing industry. The first questionnaire was directed at establishing the relative importance of factors that influence waste and pollution control investment decisions as well as the perceptions and preferences of managers with regard to various pollution control policy options. Descriptive statistics such as the modal class were used to summarize the distribution of opinions and viewpoints within the research population. Rank ordered preference data was analyzed using a multidimensional unfolding computer algorithm. This structural multivariate statistical method is a special case of non-metric multidimensional scaling that generates perceptual maps which can aid in the discovery of the hidden structure underlying multidimensional decisions. Investments in waste and pollution control do not appear to have a high priority when compared to other strategic investments that the fish processing industry managers may make. The relative importance of factors that could influence the managers of the industry to invest in waste control equipment appear to be determined by the perceived financial returns that can be expected from such investments. Findings suggest that pollution control legislation is rendered ineffective due to inadequate enforcement. However, it appears that existing legislation needs to be rationalized in order to facilitate compliance. The most favoured pollution control instruments were those that lowered the cost of legally mandated expenses such as subsidies and income tax allowances. These were followed by permit systems which specified the allowable characteristics of discharges while allowing individual companies freedom of choice as to the method of achieving compliance. The second questionnaire was used to verify the researcher's interpretation of the findings and preliminary conclusions drawn from the replies to the first questionnaire.

M.Sc. (Environmental Management)With the rapid expansion of the industries in South Africa, environmental problems including air pollution have been increasing. Among industries that cause air pollution is the iron and steel industry. Air pollution impacts negatively on the environment and therefore the measures implemented to improve air quality by this industry were investigated. The purpose of this thesis was to critically analyse the air pollution control measures implemented by the iron and steel industry in South Africa and to find out what they are doing to address the problem of air pollution, as well as their processes in involving and encouraging community involvement with regard to environmental issues. The key findings from this study were that the South African iron and steel companies are doing their best in trying to control the problem of air pollution. Some of them do not only rely on the South African legislation, they also do self-regulation by monitoring and controlling the air pollution problems even if not strictly required to by legislation. The iron and steel industry does also involve communities, through participation in public environmental forums. Air pollution has always been an issue in South Africa, but due to a lack of enabling legislation in the country, many people were not aware of their environmental rights. Now that the South African Constitution highlights the rights of people to an environment that is not harmful to their health or wellbeing, people are becoming more aware and have started taking the issue of air pollution in a very serious light. With the new environmental legislation including the National Environmental Management Act 108 of 1009 and the National Environmental Management: Air Quality Bill (Draft 1, April 2003), most of the issues relating to air pollution will be dealt with in a better and more enforceable way.

When mining activities in some parts of the Witwatersrand were discontinued in
2000, the defunct workings started to flood. In September 2002 the mine water
started to decant from the West Rand Mine Basin (WRB) next to the Tweelopie East
Stream. Treated water is currently used in the mine's metallurgical plants and 15Ml
per day of treated water is disposed firstly into the Cooke Attenuation Dam and then
discharged into the Wonderfonteinspruit.
The aim of this study was to find and provide remediation measures as a result of
acid mine drainage and other impacting factors on the water quality and volume in
the Wonderfonteinspruit.
Conductivity and total dissolved solids (TDS) were highest at the point where the
tailings dam leached into the Wonderfonteinspruit. Sulphate was very high as was
expected due to acid mine drainage. The best way to treat the high sulphate levels is
with sulphate-reducing bacteria. To avoid the fatal flaw of many other constructed
wetlands, a continuous carbon source is provided to the bacteria in the form of
activated sewage from the Flip Human sewage treatment plant. Iron and other heavy
metals are being precipitated through oxidation reactions to form oxides and
hydroxides from the aerobic cell in the wetland. The wetlands are also known for
their ability to reduce nitrate and microbial values with great success.
In the remediation, four elements that currently do not comply with the SABS criteria
for class 0 water, were chosen for improvement: conductivity, dissolved solids,
sulphate and iron. Conductivity falls within class 1 and has a maximum of 178 mS/m
@25ºC that should be reduced to under 70 mS/m. Total dissolved solids have a
value of 1585 mg/l, which is much higher than the prescribed 450 ml/l, making it
class 2 water. The last two problematic elements are both considered as class 2
water: sulphate peaks at 592 mg/l where the preferred value is 200 mg/l, and iron
should be 0.01 mg/l, not the staggering 0.3mg/l.
iv
Alternative mitigation methods were identified and analysed for the impacts of the
five major contaminators and ultimately the solution comes down to constructed
wetlands. This is not a straightforward solution, however, and a specific design to
accommodate all the different pollutants and water quality ranges was proposed.
The other mitigation methods include a cut-off trench and pump-back system for the
tailings dam, as well as the implementation of a monitoring programme. The sewage
works should be optimised and better managed. Both the settlement and agricultural
sector need to be educated on their representative impacts on the environment and
government assistance should be available.ENVIRONMENTAL SCIENCES

The purpose of this study was to evaluate the strategic management of the Thohoyandou Block J landfill site. There are limited documented materials on strategic management of landfill sites in South Africa. As a result, this study sought to close this gap and expose new insights that it deemed to be of great importance in the management and operations of landfill sites. The capacity of a TBJ landfill site in terms of its efficiency in disposing waste, adherence to rules and procedures and the overall management of the site are the key areas of this study. The dominant types and sources of solid waste disposed at the TBJ landfill site, efficiency and effectiveness of operation of TBJ landfill site and operational challenges are the main areas covered in this study. The study adopted the mixed methods approach, involving both qualitative and quantitative research methods. Both primary and secondary data were acquired. Primary data were obtained through a questionnaire, an interview and field observation, using an observation checklist. Secondary data were obtained from ArcGIS Desktop Help 9.2 and documented materials from the Thulamela Local Municipality and the TBJ landfill site, the Integrated Waste Management Plan, Integrated Development Plan, TBJ landfill site’s monthly report, audit report and landfill site’s operating plan. Basically, field observation and a questionnaire completed by the waste manager, landfill operator and supervisor, were used to collect data on the operational challenges of TBJ landfill site and to obtain data on the efficiency and effectiveness at which the TBJ landfill site is operating. Waste pickers were interviewed and field observation was undertaken, to identify the dominant types and sources of waste disposed at the TBJ landfill site. A questionnaire completed by TBJ landfill operator, ArcGIS Desktop Help 9.2 for field measurement, reports of the amount of waste recorded and the municipality’s database, were utilized to elicit data regarding the determination of the capacity of TBJ landfill site. The results obtained revealed that the TBJ landfill site’s remaining capacity is 317 085 m3, which will be exhausted in the next 4 years. Plastics were found to be the dominant waste disposed at the TBJ landfill site, at 40%, followed by card-boxes, which constituted 32%. The dominant sources of solid waste generation in the TBJ landfill site were households, at 51%, followed by commercial, at 31% and industrial, at 11%. The absence of a weighbridge, to weigh loads of waste, frequent break down of equipment, lack of equipment required to operate the TBJ landfill site efficiently and the presence of fire hazards, were some of the

Abandoned housing projects is one of the major problems in housing industry in Peninsular Malaysia.The reasons leading to this problem are many.This catastrophe has caused multifarious problems to the stakeholders, particularly the purchasers who become the aggrieved parties.To date, there is no effective and once-and-for-all means to face the problems of abandoned housing projects.One of the factors which causes abandonment of housing projects in Peninsular Malaysia, is the lack of political will on the part of the government to adopt an affirmative better housing delivery system such as the full build then sell system and the introduction of a housing development insurance to face the problems of housing abandonment.This book provides in-depth analysis of the terms and conditions of the statutory standard sale and purchase agreements as enshrined in Schedules G, H, I and J of the Housing Development (Control and Licensing) Regulations 1989.The objective of this book, among others, is to identify the weaknesses of the terms of the agreements, if any, which may have contributed to the problem of abandoned housing projects and their consequential troubles. As comparative analyses, the terms and conditions of the sale and purchase agreements as applicable and enforced in the Republic of Singapore and New South Wales, Australia, are chose.The purpose of these comparative analyses is to find the terms and conditions in these foreign jurisdictions agreements which can be learned and adopted in the statutory standard sale and purchase agreements (Schedules G, H, I and J).It is also for the betterment of the Malaysian housing industry as a whole, and to protect the interests of the stakeholders, in particular the purchasers, as against the problems of housing abandonment and its consequences.

Abstract Uranium mineralization is associated with the gold deposits in South Africa that have been mined for more than a century. Investigations of the radiological impacts on the environment reveal that the various radioactive wastes — mostly of low activity — associated with gold and by-product uranium production do not warrant the application of anything more than basic control measures. Non-radiological pollution of the water environment is a growing problem, however, aggravated by the closure and flooding of mines. Control measures to address this problem should, as a spin-off, limit the release of radionuclides, thus helping to control future radiological pollution.

Abstract Historically in Australia, mixed Construction and Demolition waste, and Commercial and Industrial waste has been traditionally landfilled. As environmental impacts of landfilling is becoming more evident New South Wales policy makers and innovators have begun exploring an incineration strategy to use such waste to generate electricity. The objective of this study is to utilise life cycle assessment to evaluate GHG emissions from this waste treatment strategy and the environmental impact of a case study facility, in Sydney Australia. The system boundary includes the thermal treatment of waste through incineration, the electricity generation from the steam turbine and air pollution control processes involved within. The functional unit is based on 1 tonne of input mixed Construction and Demolition waste and Commercial and Industrial waste. GHG emissions are calculated and the result shows that the facility generates 0.994 MWh/tonne waste and 1.16 tCO2e/MWh electricity. This emission is lower than a brown coal fired powerplant emission factor 1.31 tCO2e/MWh. The results from this study assists understanding and policy making for the future of Energy-from-Waste as part of the generation mix in New South Wales, Australia.

The Environmental Impact Statement (EIS) for the proposed Australian National Repository for low and short-lived intermediate level radioactive waste was submitted to Environment Australia for approval in the summer of 2002 and has subsequently undergone a consultancy phase with comments sought from all relevant stakeholders. The consultancy period is now closed and responses to the comments have been prepared. This paper describes some of the issues relevant to determining the radiological risk associated with the repository to meet the requirements of the EIS. These include a brief description of the three proposed sites, a description of the proposed trench design, an analysis of the radioactive waste inventory, the proposed approach to developing waste acceptance criteria (WAC) and the approach taken to determine radiological risks during the post-institutional control phase. The three potential sites for the repository are located near the Australian Department of Defence site at Woomera, South Australia. One site is inside the Defense site and two are located nearby, but outside of the site perimeter. All have very similar, but not identical, topographical, geological and hydrogeological characteristics. A very simple trench design has been proposed 15 m deep and with 5 m of cover. One possible variant may be the construction of deeper borehole type vaults to dispose of the more active radioactive sources. A breakdown of the current and predicted future inventory will be presented. The current wastes are dominated in terms of volume by some contaminated soils, resulting from experiments to extract U and Th, and by the operational wastes from the HIFAR research reactor at ANSTO. A significant proportion of the radionuclide inventory is associated with small volumes of sources held by industry, medical, research and defence organisations. The proposed WAC will be described. These are based on the current Australian guidelines and best international practice. The preliminary radiological risk assessment considered the post-institutional control phase in detail with some 12 scenarios being assessed. These include the impact of potential climate change in the region. The results from the risk assessment will be presented and discussed. The assessment work is continuing and will support the license application for construction and operation of the site. Please note that this is not the final assessment for the licence application.

In September 2006 an outbreak of 'Bluetongue like' disease struck the cattle herds in Israel. Over 100 dairy and beef cattle herds were affected. Epizootic hemorrhagic disease virus (EHDV) (an Orbivirusclosely related to bluetongue virus (BTV)), was isolated from samples collected from several herds during the outbreaks. Following are the aims of the study and summary of the results: which up until now were published in 6 articles in peer-reviewed journals. Three more articles are still under preparation: 1. To identify the origin of the virus: The virus identified was fully sequenced and compared with the sequences available in the GenBank. It appeared that while gene segment L2 was clustered with EHDV-7 isolated in Australia, most of the other segments were clustered with EHDV-6 isolates from South-Africa and Bahrain. This may suggest that the strain which affected Israel on 2006 may have been related to similar outbreaks which occurred in north-Africa at the same year and could also be a result of reassortment with an Australian strain (Wilson et al. article in preparation). Analysis of the serological results from Israel demonstrated that cows and calves were similarly positive as opposed to BTV for which seropositivity in cows was significantly higher than in calves. This finding also supports the hypothesis that the 2006 EHD outbreak in Israel was an incursive event and the virus was not present in Israel before this outbreak (Kedmi et al. Veterinary Journal, 2011) 2. To identify the vectors of this virus: In the US, Culicoides sonorensis was found as an efficient vector of EHDV as the virus was transmitted by midges fed on infected white tailed deer (WTD; Odocoileusvirginianus) to susceptible WTD (Ruder et al. Parasites and Vectors, 2012). We also examined the effect of temperature on replication of EHDV-7 in C. sonorensis and demonstrated that the time to detection of potentially competent midges decreased with increasing temperature (Ruder et al. in preparation). Although multiple attempts were made, we failed to evaluate wild-caught Culicoidesinsignisas a potential vector for EHDV-7; however, our finding that C. sonorensis is a competent vector is far more significant because this species is widespread in the U.S. As for Israeli Culicoides spp. the main species caught near farms affected during the outbreaks were C. imicolaand C. oxystoma. The vector competence studies performed in Israel were in a smaller scale than in the US due to lack of a laboratory colony of these species and due to lack of facilities to infect animals with vector borne diseases. However, we found both species to be susceptible for infection by EHDV. For C. oxystoma, 1/3 of the Culicoidesinfected were positive 11 days post feeding. 3. To identify the host and environmental factors influencing the level of exposure to EHDV, its spread and its associated morbidity: Analysis of the cattle morbidity in Israel showed that the disease resulted in an average loss of over 200 kg milk per cow in herds affected during September 2006 and 1.42% excess mortality in heavily infected herds (Kedmi et al. Journal of Dairy Science, 2010). Outbreak investigation showed that winds played a significant role in virus spread during the 2006 outbreak (Kedmi et al. Preventive Veterinary Medicine, 2010). Further studies showed that both sheep (Kedmi et al. Veterinary Microbiology, 2011) and wild ruminants did not play a significant role in virus spread in Israel (Kedmi et al. article in preparation). Clinical studies in WTD showed that this species is highly susceptibile to EHDV-7 infection and disease (Ruder et al. Journal of Wildlife Diseases, 2012). Experimental infection of Holstein cattle (cows and calves) yielded subclinical viremia (Ruder et al. in preparation). The findings of this study, which resulted in 6 articles, published in peer reviewed journals and 4 more articles which are in preparation, contributed to the dairy industry in Israel by defining the main factors associated with disease spread and assessment of disease impact. In the US, we demonstrated that sufficient conditions exist for potential virus establishment if EHDV-7 were introduced. The significant knowledge gained through this study will enable better decision making regarding prevention and control measures for EHDV and similar viruses, such as BTV.
