The development of agricultural productivity and the management of water along sustainable ecological, economic and social trajectories require an integrated approach. Integrated water management is knowledge intensive across multiple scales. As New Zealand moves to set limits on water quantity...

This paper provides a concise introduction to and evaluation of the Lake Taupo nitrogen cap and trade program established as part of Waikato Regional Council's recent Regional Plan Variation Five. The policy establishes a catchment-wide cap on nitrogen losses by allocating farmers individual...

The River Values Assessment System (RiVAS) uses a combination of expert panels and multi criteria analysis to identify primary attributes (or main features) of river values (e.g., whitewater kayaking, native birds) and their key indicators. The resulting data set is used to rank rivers for their...

Adequately representing dynamic characteristics of land use change and forestry in computable general equilibrium models is challenging but essential if modellers are to provide credible assessments of policies that directly or indirectly influence these phenomena. In this paper, we show how a...

New Zealand houses are cold, damp, and poorly insulated by international standards. Our substandard housing stock has negative effects on health, quality of life, productivity, winter air quality, energy use and transmission. Investment in home energy efficiency is below the socially optimal...

NPV and LEV are established and common approaches to valuing single rotation and infinite rotation forests respectively, when the rotation age is fixed in advanced. More recently, Real Options approaches have been employed to value single and infinite rotation forests with a flexible harvest...

Australia has long been a major exporter of the products of broadacre agriculture, a production system well suited to the economic and climatic conditions of the country. According to the conventional wisdom, Australia holds a comparative advantage in these products, among which wheat and...

This paper explains a short term forecasting approach that uses whole milk powder prices from Fonterra’s globalDairyTrade. The latter provides forward contract prices eight months out from each event. The cumulative impact of up to seven successive events provides reasonable expectations...

As part of international climate change policy, voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines, adverse selection will reduce efficiency since participants will...

With current concerns about climate change and the general status of the environment, there is an increasing expectation that products have sustainability credentials, and that these can be verified. Labelling is a common method of communicating certain product attributes to consumers that may...
