The intensity of agricultural production affects both nutrient and greenhouse gas emissions. Environmental policy designed to reduce one type of pollution may have complementary effects on the other type. This paper explores this issue in the Lake Rotorua catchment in New Zealand using an...

Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions. This document estimates functions and creates projections for...

Emissions trading and nutrient trading interact in critical ways. The agricultural sector is a major emitter of both nutrients and greenhouse gases in New Zealand. Thus the simultaneous implementation of such systems will have a large impact on the farmers in affected catchments. Many of the...

The greatest friction in trade and fishery between Japan and New Zealand was the Total Economic Relationship, which was insisted by the PM of NZ. NZ wanted to export dairy foods in exchange for admitting fishing. Both governments experienced a long and tough negotiation. Recently frictions have...

Lakes Taupo and Rotorua are important to New Zealand, but declining lake water quality is increasingly becoming a problem. Primary producers are said to be impacting heavily on the lakes' water quality through discharges that reach them through streams and ground water. The paper discusses the...

This study examined the economic impact of a wintering barn facility on a dairy farm in the Tararua District, relative to its ability to reduce nitrogen leaching, as a means of achieving Horizon’s proposed nitrogen discharge limit. The analysis showed that the provision of a wintering facility...

This paper describes further progress in a new approach to stakeholder consultation for policies about agricultural land uses and water quality in rural waterways; a process that was begun early in 2012. The initial consultation events provided the basis for a future draft of Greater Wellington...

This paper reviews the progress to date of the Canterbury Water Management Strategy and identifies key developments and emerging issues. The paper examines the provision of storage, water use efficiency, environmental flow adjustments, nutrients from land use intensification, biodiversity...
