made in one situation to related circumstances. The benefit transfer process is typically reliant on the availability of a number of source studies which have appropriate levels of reliability and relevance to the issue of interest. However, the limited number of non-market valuation studies to draw on for source values currently limits the benefit transfer process. In this paper, an alternative approach to benefit transfer is outlined where a series of valuation studies were specifically performed to build a reference data base of values for benefit transfer purposes. The choice modelling technique was used to estimate community values for protecting soil, water and vegetation stocks in Queensland, Australia, where both state and regional populations were... |

Key policy issues relating to protection of the Great Barrier Reef from pollutants generated by agriculture are to identify when measures to improve water quality generate benefits to society that outweigh the costs of reducing pollutants. The research reported in this paper makes a key contribution in several key ways. First, it uses the improved science understanding about the links between management changes and reef health to bring together the analysis of costs and benefits of marginal changes, helping to demonstrate the appropriate way of addressing policy questions relating to reef protection. Second, it uses the scientific relationships to frame a choice experiment to value the benefits of improved reef health, and links improvements explicitly to... |

The Fitzroy Basin is one of the largest catchment areas in Australia covering 143,000 km² and is the largest catchment for the Great Barrier Reef (GBR) lagoon. Recent research has identified that poor water quality is having negative impacts on the GBR. Grazing beef cattle is the dominant land use in the Fitzroy Basin (90% by area) and has been identified as the major contributor of sediment (~%90) and organic nutrient loads to the GBR lagoon. A bioeconomic model has been developed which determines the cost ($/tonne of sediment) incurred by graziers in implementing strategies that increase ground cover and land condition. The results demonstrate the implications of land type, grazing pressure, tree basal area and enterprise operation on optimal grazing... |

The focus of the research reported in this paper has been to estimate recreation values for beaches over approximately 1400 kilometres of coastline along the Queensland coast. The study is notable at an international level because it assesses recreation values to a general type of recreation asset rather than to a specific site, and because it focuses on the values of the local resident population. Negative binomial models have been used to estimate both the visit rate and recreation values associated with beach visits in different regional areas. The value of a single beach visit was estimated per person at $35.09, which extrapolates to $450 million in beach recreation values per annum. These values are likely to be conservative because opportunity costs... |

The focus of this paper is to compare different evaluation frameworks for selecting landholder proposals to improve water quality. The case study is a water quality tender performed in the Burdekin region in Northern Australia in 2007/2008 where bids could be assessed using an inputs-based best management practice scorecard or an outputs-based auction metric. The scorecard approach and other variants of multi-criteria analysis are commonly applied in grant schemes, where landholder proposals are rated by a range of inputs-based criteria. Output-based approaches are typically applied in water quality and conservation tenders, where an environmental benefits index is constructed to summarise the cost-effectiveness of each proposal. The case study evaluation... |

In this paper, estimates of value for recreational fishing are reported for three major freshwater impoundments in Queensland, Australia, using both travel cost and contingent valuation methods. Policy analysts often require estimates of value when analysing the importance of recreation against other uses of impoundments, or when considering the potential for further investments, such as with fish stocking programs. Different forms of the travel cost method are used to estimate separate consumer surpluses associated with two key subgroups of recreational anglers: frequent and occasional anglers. A contingent valuation study is used to estimate the marginal values associated with a potential improvement in fishing experience. The results of the travel cost... |

Blarney, Common and Quiggin (1995) (BCQ) suggest that responses to contingent valuation (CV) questionnaires may be framed either according to the extent of individual benefits received, or according to wider views about ethical frameworks, impacts on other people, or desired societal levels. They characterise the individual benefit approach as a consumer model, and responses indicating wider concerns as citizen preferences. Citizen value responses are held to invalidate the economic assumptions underlying the use of CV. Hence, they hypothesize that the incorporation of CV results into benefit-cost analysis is problematic. In this comment we suggest that there are several flaws with the citizen value hypothesis. These can be grouped into arguments about... |

This paper presents the results of a choice modeling survey of households in Queensland to assess values for reductions in national greenhouse emissions by 2020. The study is novel in two main ways. First, labeled alternatives were used to assess whether the types of broad management options for reducing net emissions (green power, alternative technologies or carbon capture) are significant in understanding preferences for reducing emissions. Second, the importance of the level and type of uncertainty involved in reductions is tested. They include (1) the uncertainty of achieving emissions reduction and (2) the uncertainty of international participation as the percentage of total global emissions covered by international agreements. The results of this... |

This paper reports research seeking to understand the economic implications for central Queensland graziers of participating in a carbon trading scheme and to measure the likely participation of graziers in an emissions trading scheme under various market design scenarios. An initial desktop study was undertaken to compare an enterprise which produced only cattle to one which produced cattle and sequestered carbon. The findings from this analysis were used to inform the design of an experimental auction to test alternative carbon trading scenarios. An experimental workshop was conducted at seven locations across central Queensland with a range of beef producers, extension officers and consultants. Participants were presented with a scenario in which they... |

The future viability of the sugar industry has been questioned in several major reports. It is generally agreed that the industry will have to undergo some changes. One of the key issues in the most comprehensive of these reports, the Hildebrand report (Hildebrand 2002), is the need to improve economic efficiency in the industry. At the grower level, the report considers many farms to be economically unviable and advocates the need to increase farm size to achieve better economies of scale. Some growers will not be able to expand and a more viable economic option might be to diversify farm enterprise income. Generally, the main advice farmers receive about alternative crops is based on gross margins, but there are other components of crop diversification... |

Metrics for evaluating environmental trade-offs can be developed with varying levels of consistency across case study sites. A key issue is whether standard evaluation experiments can be conducted over multiple sites, or whether experiments have to be tailored to each case study application. To test how useful a consistent approach is, choice modelling (CM) has been used in a number of countries. Choice modelling assess the trade-offs households are prepared to make between water use restrictions, maintaining environmental conditions in waterways, and increased water costs. This research paper reports the results of the Queensland survey. The results show that it is not possible to downplay case study framing issues and that it is not appropriate to... |

The Carbon Farming Initiative (CFI) and other carbon trading programs have been promoted as alternative sources of income for agricultural producers, particularly those on marginal land. This paper presents the results of a bioeconomic model developed to compare the relative returns from a beef enterprise against changing regrowth management practices to sequester additional carbon and sell carbon offsets. The model is constructed based on a 1000 hectare parcel of land in Central Queensland and is calculated for two landtypes; Brigalow and Eucalypt. Assuming zero transaction costs and a 20 year contract period, a carbon-cattle enterprise has higher returns that a cattle-only enterprise at relatively low carbon prices for both land types. However, results... |

The aim of this study was to estimate the values to protect the health of the Great Barrier Reef (GBR) at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from nearly 1,000 km to over 4,000 km from Brisbane. The results suggest that the average WTP across Australian households is $21.68 per household per annum for five years. There was some evidence of distance decay in values. Most decline occurred once outside the home... |

Designing a choice modelling (CM) experiment to place a value on increasing protection of the Great Barrier Reef (GBR) raises complex issues. The size and diversity of the GBR, and the number of different pressures impacting on it, mean protection and improvement scenarios can be drafted in several different ways. This report discusses some of the considerations in selecting, describing and combining choice attributes. It also looks at how to incorporate tests for geographic scale (size) and scope (complexity) differences into the design of the CM survey instrument. The potential to include information about management options designed to achieve increased protection, and the associated risk and uncertainty, is also discussed. |

Australian governments continue to commit significant resources to the protection of the Great Barrier Reef. Funding for the Reef Rescue Programme is focused on reducing the impact of agricultural production on water quality. Information about the costs and benefits of funding proposals is limited. As a result, the key challenge for policy makers is to identify where funding is most efficiently applied. While there is adequate information about the costs of various inputs for reducing water quality, the costs of achieving various outputs is much more limited. Water quality tenders show the opportunity costs of changing agricultural practices. They allow policy makers to better understand the potential costs of misallocating public resources. It also... |

The Queensland Livestock Market Reporting Service (QLMRS) was established in 1980 by the livestock and Meat Authority of Queensland. Weekly reports on the major live cattle auctions in Queensland indicate the prices of different types of cattle, categorised by their age, sex, weight, fat score and type of feed. Previous research has suggested that differences in these characteristics account for only some of the price variation observed at cattle auctions. This paper investigates other characteristics not included in the QLMRS market reports which may be important in determining the price of cattle. Data on the standard QLMRS characteristics and on other potentially important characteristics have been collected by the authors for a large number of lots of... |
