| 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. A second part considers options for modelling agent heterogeneity, especially risk preferences of farmers, and the impacts on decision-making. The final section outlines the MAS that the authors will be constructing over the next few years and the types of... |

| The recent rise of food cost in world markets has accelerated the research examining the underlying factors for this rise. The present research investigated the separate and combined impacts of three factors thought to contribute to the price rise: adverse weather events, strong and sustained growth in high populated countries, and increased biofuels production. The research further analysed the effects of these price rises on consumption expenditures in Brazil, China and India. Analyses were carried out using a partial equilibrium trade model with a focus on the 2004 to 2007 period. The modelling suggests that the most important factor behind the price rise depends on the commodity, with maize/corn, oilseeds, and sugar most affected by biofuels, while... |

| This paper takes the capital based approach to sustainability and applies this to examine the sustainability of different farming methods. The capital based approach argues that for future generations to be as well off as the present than the capital base should at least be maintained. The paper explores some of the issues around this approach such as the definition of capitals, their measurement and weakness in the approach which do not account for the resilience of system and/ or the substitutability of capitals. The paper outlines how this could be applied to agriculture and show sustainability across different farming methods. The data used is from the ARGOS (Agricultural Research Group on Sustainability) project which has collected data on social,... |

| 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. Regrouping of the properties according to farmer typologies does, however, result in the identification of some significant differences in economic outcomes between different “types” of farmers. |

| 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 influence their choices. There are different types of labels with several functions. The aim of this study was to investigate consumers‟, attitudes, knowledge and preferences towards certain sustainability claims on food products across countries; particularly attitudes towards the display of the reduction of carbon emissions were examined in this research. A web-based consumer survey undertaken in the United Kingdom and Japan showed similarities between consumers in... |

| The impact of biotechnology is an important consideration for New Zealand. The country depends significantly on agricultural production and exports (Ministry of Agriculture and Forestry, 2004), and has relied in part on modern biotechnology for productivity increases over the last 20 years (Evenson & Gollin, 2003; Jacobsen & Scobie, 1999; Ovenden, Anderson, Armstrong, & Mitchel, 1985). A recent survey of individuals in agriculture and biotechnology generated a comprehensive list of products and processes that are derived from four specific biotechnologies and are commercially significant in agriculture (Kaye-Blake, Saunders, Emanuelsson, Dalziel, & Wreford, 2005). This innovative research generated primary data on the actual impacts that... |

| In the land-based sectors, agricultural production generally is a source of carbon, while forestry may be thought to act as a sink. This paper focuses on new research examining the interaction of the two. The core of the research is the Lincoln Trade and Environment model (LTEM), a partial equilibrium model which links trade in NZ with the main trading countries overseas, through to production and associated environmental consequences . This paper reports on research expanding the model to include forestry from incorporating the capabilities of the Global Forest Products Model (GFPM) into the LTEM and hence producing an integrated model of agricultural and forestry land-uses for NZ and overseas. The paper extends the environmental modelling capabilities of... |
