    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 age.

    In this paper we conduct an analysis of the implementation of HACCP/RMP in the NZ Meat Industry based on the data collected from our recent survey. Nonparametric methods are used to measure the association between plant characteristics such as size, age, activities, and food safety management practices and HACCP/RMP adoption motivations, implementation problems, benefits, and costs. Results give insights into the ongoing process of mandatory RMP in New Zealand.

    Multi-Agent Simulation (MAS) models are intended to capture emergent properties of complex systems that are not amenable to equilibrium analysis. They are beginning to see some use for analysing agricultural systems. The paper reports on work in progress to create a MAS for specific sectors in New Zealand agriculture. One part of the paper focuses on options for modelling land and other resources such as water, labour and capital in this model, as well as markets for exchanging resources and commodities.

    With the impending introduction of an Australian Carbon Pollution Reduction Scheme, farmers andlandholders in rural Australia have increased opportunities to participate in the market. This includes theadoption of land-use change to sequester additional carbon in exchange for carbon credits and theproduction of a renewable energy source (biofuels). However, these land-use changes compete withexisting farm enterprises and may contain significant transaction costs.

    Across diverse ecosystems, greater climatic variability tends to increase wildfire size, particularly in Australia, where alternating wet–dry cycles increase vegetation growth, only to leave a dry overgrown landscape highly susceptible to fire spread. Aboriginal Australian hunting fires have been hypothesized to buffer such variability, mitigating mortality on small-mammal populations, which have suffered declines and extinctions in the arid zone coincident with Aboriginal depopulation.

    For 25 years the Australian Landcare program has encouraged rural land managers to work cooperatively to resolve natural resource management issues across the nation. Landcare has spread and the model is used internationally. Despite its successes, Landcare has come under criticism for not sufficiently directing land management practices towards environmental sustainability. This criticism sees it as having maintained the “status quo”.

    Groundwater vulnerability assessment is an important task in water resources and land management. The most sophisticated among the vulnerability assessment techniques is the GIS-based DRASTIC model. However, despite its popularity, it is marred with excessive subjectivity glitches; little research has been conducted to address the shortcomings associated with this method. This study investigates various issues regarding the application of the GIS-based DRASTIC model through a critical review of relevant literatures.

    Eco-efficiency has emerged as a management response to waste issues associated with current production processes. Despite the popularity of the term in both business and government circles, limited attention has been paid to measuring and reporting eco-efficiency to government policy makers. Aggregate measures of eco-efficiency are needed, to complement existing measures and to help highlight important patterns in eco-efficiency data.This paper aims to develop aggregate measures of eco-efficiency for use by policy makers.

    Recent environmental assessments have highlighted the extent of land degradation inAustralia and the significant costs involved in addressing it. With projected investment costsrunning into tens of billions of dollars, it is not surprising that greater attention is now beingfocussed on who should pay. One idea gathering significant momentum has been theimposition of an environmental levy.
