    The effectiveness of biosecurity measures at national borders is influenced by thebehaviour and levels of involvement of travellers. Involvement is the importance orrelevance of an object or situation to an individual. Involvement helps regulate theway in which people receive and process information and thus influences the extentof information searching for decision making, and information processing andpersuasion. In this study, we drew on the concept of involvement to investigate theresponse of individuals to New Zealand biosecurity requirements.

    New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development.

    The emerging biofuel sector has drawn great interest as an alternative source of fuel for transportation. The expansion of biofuels greatly impacts world agricultural markets, since currently, the primary feedstocks for ethanol and biodiesel production are field crops and their derived products. There is great interest in the potential of countries to expand their biofuel sectors through increased production of feedstocks. The long-term potential for developing first-generation biofuels in many countries depends on a large and constant supply of feedstocks.

    The Agriculture Research Group on Sustainability (ARGOS) monitors a wide ange of environmental, social, economic and management parameters on matched cohorts of organic, conventional and integrated farms in the sheep/beef and kiwifruit sectors. Over six years significant differences have been found in farm costs and revenues between management systems, but few differences have been identified between management systems in “bottom-line” indicators of profitability, and there is greater variability within cohorts than between them.

    Agri-environmental indicators (AEIs) developed by the OECD have been used to assess the environmental performance of the agricultural sector in developed countries. The Agricultural Research Group on Sustainability (ARGOS) in New Zealand has investigated using these AEIs to assess the performance of individual kiwifruit orchards. ARGOS is following panels of orchards to investigate the impacts of organic and conventional management systems on economic, sociological, and environmental dimensions of farming.

    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.

    Based on the results of a probit model estimated from a survey of 1625 farmers from seven major dairying regions in New Zealand, farmers’ attitudes (perception about the overall benefits) appear to be are a major governing factor of waterway fencing in all regions. While fencing in Northland and West Coast regions was lower than elsewhere, owner/operators in those regions tended to fence more than farmers with other types of ownership structures. Environmental issues also appeared to be important; however the level of environmental awareness did not reflect the actual degree of fencing.

    In New Zealand, regional councils have the task of sustainably managing rivers andtheir flows. In trying to achieve this task they face enormous challenges including theneed to allocate flows amongst often highly disparate in- (e.g., angling, kayaking,native fish and birds) and out-of-river (e.g., irrigation and hydro energy) values/needs.To aid in this task these councils need to know which rivers or parts of rivers arerelatively more or less important on national, regional and local bases, for particularvalues.

    The 2007-08 drought affected a large area of New Zealand. This paper describes the analytical framework used to estimate the associated regional and national economic impacts. Results suggest that calculating drought economic impacts by applying standard farming industry multipliers to changes in farm gate output can greatly overstate both regional and national economic impacts. Calculating impacts using differences between forecast and actual farm production and expenditure by farm type is both feasible and produces far more reliable impact estimates.

    Biosecurity incursion response decisions require timely, high quality informationinvolving science and economics. The value of the impact on indigenous biodiversityis a key aspect of the economics typically involving cost-benefit analysis. Thehypothetical incursion of Biosecurity New Zealand’s top priority weed hydrilla(Hydrilla verticillata) in a typical New Zealand lake (Lake Rotoroa otherwise knownas Hamilton Lake) elicits dollar values of impacts on indigenous biodiversity in afreshwater environment.
