Water Quality Management in Lake Rotorua: A comparison of Regulatory Approaches using the NManager Model AgEcon
Anastasiadis, Simon; Nauleau, Marie-Laure; Kerr, Suzi; Cox, Tim; Rutherford, Kit.
The life satisfaction approach has recently emerged as a new technique in the suite of options available to non-market valuation practitioners. This paper examines the influence of ecosystem diversity on the life satisfaction of residents of South East Queensland, Australia. It is found that, on average, a respondent is willing-to-pay approximately AUD$20,000 in household income per annum to obtain a one-unit improvement in ecosystem diversity. This result indicates that the life satisfaction effects of improvements in ecosystem diversity are substantial, and greater than the welfare effects implied by studies using more conventional non-market valuation techniques.

Assessing design options for a Nutrient Trading System using an integrated model AgEcon
Lock, Kelly; Kerr, Suzi; Cox, Tim; Rutherford, Kit.
Water quality in many New Zealand waterways is currently declining leading to lakes and rivers being closed for contact recreation such as swimming and potentially threatening our clean, green image. Much of this decline is associated with an increase in the nutrient loss from agriculture in the surrounding catchment. Nutrient trading systems are being considered in a number of catchments across the county to restrict the nutrient loss entering the waterways and thus improve the water quality. Such a system is currently being implemented in Lake Taupo and Environment Bay of Plenty is exploring actively the use of such a system to manage nutrient loss in the Lake Rotorua catchment. Yet the design of such systems is challenging. In a collaborative effort...
