A number of decisions need to be made when setting up a nutrient trading system including defining a target, allocating allowances and setting up a monitoring system. To ensure that the nutrient trading system implemented operates in harmony with existing regulation, existing work and...

This paper explores how to enhance the role for academic research (natural sciences, economics and their integration; and stakeholder management) within the development and implementation of water quality policy in New Zealand. Our focus is on the use of market based instruments and particularly...

A nutrient trading system is one mechanism that is currently being considered to control and reduce nutrient loss into Lake Rotorua. However this may not be the best mechanism for controlling nutrient loss from all sources. A more comprehensive system improves efficiency and decreases market...

Declining water quality as a result of increased nutrient leaching is a serious and growing concern, both internationally and in New Zealand. Water pollution issues have traditionally been addressed with command-and-control type regulation, but market-based nutrient trading schemes are becoming...

This paper examines six different approaches to nutrient management, and simulates the economic costs and environmental impacts associated with them using NManager, a partial equilibrium simulation model developed by Motu and NIWA, the National Institute for Water and Atmospheric Research. We...

Risk (and often the certainty) of adverse environmental outcomes motivates environmental regulation; other risks also affect welfare outcomes. Economic instruments are one way to reduce environmental risk while maintaining flexibility that helps manage other risks. However regulation not only...
