Ecological assessments and monitoring programs often rely on indicators to evaluate environmental conditions. Such indicators are frequently developed by scientists, expressed in technical language, and target aspects of the environment that scientists consider useful. Yet setting environmental policy priorities and making environmental decisions requires both effective communication of environmental information to decision makers and consideration of what members of the public value about ecosystems. However, the complexity of ecological issues, and the ways in which they are often communicated, make it difficult for these parties to fully engage such a dialogue. This paper describes our efforts to develop a process for translating the indicators of...

Integrating economic values and catchment modelling
Provedor de dados: 31
Autores: Kragt,   Marit Ellen; Bennett,   Jeffrey W.
Integrated catchment policies are widely used to manage natural resources in Australian catchments. Decision support tools available to aid integrated catchment management are often limited in their integration of environmental processes with socio-economic systems. Fully integrated models are required to support assessments of the environmental and economic trade-offs of catchment management changes. A Bayesian Network (BN) model is demonstrated to provide a suitable approach to integrate environmental modelling with economic valuation. The model incorporates hydrological, ecological and economic models for the George catchment in Tasmania. Information about the non-market costs and benefits of environmental changes is elicited using Choice Experiments,...

Policy responses to invasive native species: issues of social and private benefits and costs
Provedor de dados: 31
Autores: Farquharson,   Robert J.; Kelly,   Jason A.; Welsh,   Pam; Mazur,   Kasia; Bennett,   Jeffrey W.
Farm and catchment managers in Australia face decisions about controlling invasive native species (or scrub) which may infest agricultural land. The treatment of this land to remove the infestation and re-establish native pastures is likely to be expensive for landholders. Yet there are potential social benefits from such remediation and so a policy question arises of what to do to about facilitating such change. New South Wales state government legislation addresses this issue through regulations, and the Catchment Management Authorities are responsible for administering public funds to achieve associated natural resource improvements. However, the extent of the private costs and social benefits associated with such changes are not known, which precludes...

An Integrated Assessment approach to linking biophysical modelling and economic valuation tools
Provedor de dados: 31
Autores: Kragt,   Marit Ellen; Bennett,   Jeffrey W.; Jakeman,   Tony.
Natural resource management (NRM) typically involves complex decisions that affect a variety of stakeholder values. Efficient NRM, which achieves the greatest net environmental, social and financial benefits, needs to integrate the assessment of environmental impacts with the costs and benefits of investment. Integrated assessment (IA) is one approach that incorporates the several dimensions of catchment NRM, by considering multiple issues and knowledge from various disciplines and stakeholders. Despite the need for IA, there are few studies that integrate biophysical modelling tools with economic valuation.  In this paper, we demonstrate how economic non-market valuation tools can be used to support an IA of catchment NRM changes. We develop a Bayesian...

Ambivalent statements in contingent valuation studies: inclusive response formats and giving respondents time to think
Provedor de dados: 31
Autores: Svedsater,   Henrik.
A recent concern in the valuation literature is the uncertainty respondents feel when posed with willingness-to-pay questions for environmental amenities in hypothetical market scenarios. Using a multiple-bounded discrete-choice format, the results indicate that respondents become less ambivalent when allowed considerable time to think about the valuation task before a response is elicited. In particular they tend to reduce the reported willingness to pay associated with low certainty of paying, hence resulting in more conservative welfare estimates. Implications for the application of environmental valuation techniques are discussed.

Using choice experiments to value river and estuary health in Tasmania with individual preference heterogeneity
Provedor de dados: 31
Autores: Kragt,   Marit Ellen; Bennett,   Jeffrey W.
Choice experiments (CE – otherwise known as Choice Modelling) have become a widespread approach to environmental valuation in Australia, with many examples assessing the tradeoffs between river catchment management and socio-economic impacts. There is, however, limited information on the values of Australian estuaries. Furthermore, none of the existing valuation studies address catchment management changes in Tasmania. The CE study reported in this paper aims to elicit community preferences for the protection of the rivers and estuary of the George catchment in north-eastern Tasmania. Results from conditional and mixed logit models show that respondents are, on average, willing to pay between $2.47 and $4.46 for a km increase in native riverside vegetation...

Environmental value and valuation over time
Provedor de dados: 31
Autores: Scheufele,   Gabriela; Bennett,   Jeffrey W.
Time and value are related concepts that influence human behaviour. Although classical topics in human thinking throughout the ages, few environmental economic non-market valuation studies have attempted to link the two concepts. Economists have estimated non-market environmental values in monetary terms for over 30 years. This history of valuation provides an opportunity to compare value estimates and how valuation techniques have changed over time. This research aims to compare value estimates of benefits of a protected natural area. In 1978, Nadgee Nature Reserve on the far south coast of New South Wales was the focus of the first application of the contingent valuation method in Australia. This research aims to replicate that study using both the...
