We develop a catchment scale modeling framework to identify cost-effective strategies for joint onsite abatement and offsite mitigation of land-based pollution from agricultural activities that pose a risk to water quality in the Great Barrier Reef (GBR). An illustrative example of the Barron catchment in north Queensland is used to demonstrate an approach to specify social planner's problem for non-point source pollution management as a cost minimisation model to meet a specified reduction in land-based pollution emissions at the receiving waters of GBR. We focus on the tradeoffs between onsite pollution control and offsite pollution mitigation under a collective contract for nutrient reduction at a sub-catchment level and discuss implementation options.

Using focus groups to design a choice modelling questionnaire for estimating natural resource management benefits in NSW

The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean) using choice modelling (CM). The survey aimed to find out respondents’ attitudes about, and preferences for, potential natural resource management (NRM) improvements. In total, 3,997 responses were collected from seven different locations in NSW. Fourteen split samples were established to allow for testing of incentive compatibility in CM, the impact of respondent location on values held, and scale effects. This research report describes the development...

Choice modelling in the development of natural resource management strategies in NSW

In this study, focus group discussions were used to design a choice modelling (CM) questionnaire to estimate community wide values for the environmental and social benefits provided by natural resource management changes in the Namoi, Lachlan and Hawkesbury-Nepean catchments. This report describes the logistics of the focus groups and outlines the main conclusions drawn from the discussions. The research team conducted eight focus groups in the main urban areas of the regions where the CM survey will be conducted (Tamworth, Cowra, Goulburn and Sydney). How the CM questionnaire was developed with focus group participant input is also discussed in the report. The focus group meetings resulted in a draft questionnaire to be refined in consultation with...

Location differences in communities’ preferences for environmental improvements in selected NSW catchments: A Choice Modelling approach

Protecting environmental services generates social benefits. At the same time, private landholders supplying these benefits may face some costs. To provide these services efficiently, policy makers need information about community values for the environment as well as landholders’ costs. This study explores how choice modelling (a non-market valuation technique) is used to estimate comment values. These include use and non-use values for increasing environmental quality in NSW catchments. Non-market valuation techniques for estimating environmental values are reviewed. This is followed by a discussion of methodological aspects of the choice modelling technique and its potential as a regional planning tool for Catchment Management Authorities (CMA’s)

A choice modelling (CM) study was conducted to elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean). This paper presents results of research designed to investigate variations in WTP across different communities including local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effect’. The analysis involved both conditional logit and random parameters logit models.

Framing for incentive compatibility in choice modelling

To elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean), a choice modelling (CM) study was conducted. This report presents results of research designed to investigate variations in WTP across different communities. The communities included local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effects’. The analysis involved both conditional logit and random-parameters logit models. Natural resource management (NRM), including Catchment Management Authorities (CMAs), can use the non-market values obtained from this study to guide their investment decisions.

The incentives that motivate respondents to reveal their preferences truthfully have been a long-standing area of research in the non-market valuation literature. A number of studies have been undertaken to investigate incentive compatibility in nonmarket valuation. Most of these used laboratory environments rather than field surveys (e.g. Carson and Burton, 2008, Harrison, 2007, Lusk and Schroeder, 2004, Racevskis and Lupi, 2008). Only a few studies investigating incentive compatibility have considered multi-attribute public goods with an explicit provision rule in a choice experiment (Carson and Groves, 2007, Collins and Vossler, 2009, Carson and Burton, 2008). The design of a choice modelling study that avoids strategic behaviour has proven particularly...

Policy responses to invasive native species: issues of social and private benefits and costs

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...

The Effects of a Provision Rule in Choice Modelling

This report presents results of research designed to investigate variations in willingness to pay (WTP) estimates across different scales and scopes of environmental investments. The goal is to help catchment management authorities better prioritise their natural resource management actions at both catchment and farm levels. Five split samples were used to test for scale and scope effects. A choice-modelling (CM) analysis was used to elicit household WTP for improvements in environmental quality attributes in the Namoi catchment. The approach was developed so that value estimates could be more accurately transferred between different action scopes.
