| 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 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... |

| 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 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... |

| Growers in the sugarcane industry have been struggling under financial pressure for several years. One option to improve farm viability might be to diversify farm enterprise income. Choice Modelling, an economic valuation technique, was used to explore the trade-offs growers make between different attributes of diversification, and how their choices may be related to certain socio-economic characteristics. Application of the technique involved surveys of cane growers in three regions of Central Queensland. This is a novel approach to assessing grower intentions that has the potential to reveal detailed information about influences on grower choices. |

| Option values may be an important component of non-use values when development options for environmental assets are considered. These are values that the community might hold for maintaining options to make future choices about allocating resources. However, option values are very difficult to define, at both theoretical and practical levels, and there has been a retreat over the past decade to the more inclusive concept of option prices. In the present paper, estimates of option values are reported for retaining unallocated water in reserve rather than using it for current development. The use of option values rather than option prices is justified on the basis that the focus is on nonuse values, and demand and supply uncertainties have been minimised.... |

| Policy makers are often interested in transferring non-market estimates of environmental values from a ‘source’ study to predict economic values at a ‘target’ site. While most applications of the benefit transfer process involve an opportunistic search for suitable source studies, there are some examples available of more systematic approaches to developing a framework of values for benefit transfer processes. A key issue in developing such a framework is to deal with adjustment factors, where value estimates might vary systematically according to the context of the trade-offs. Previous research has identified that large differences in scope, such as between national and regional contexts, do affect values and hence benefit transfer. The research reported... |
