    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.

    This study examines the economic potential of producing a wheat (Triticum aesitivum) and grain sorghum (Sorghum bicolor (L.) Moench) rotation with three different tillage strategies compared to the Conservation Reserve Program (CRP) in a semi-arid region. This research uses stochastic efficiency with respect to a function (SERF) to determine the preferred management strategies under various risk preferences and utility-weighted certainty equivalent risk premiums.

    Since early 1990’s Tanzania has implemented far reaching macroeconomic and structural reforms which has led to substantial socio-economic development.  GDP growth per annum has almost doubled over the last decade from 4.1% in 1998 to 7.4% in 2008, with an average growth of 7% per annum. This is historically high for Tanzania and comparable to the performance of fastest growing economies in sub-Saharan Africa.  GDP growth peaked in 2004 at 7.8%, but severe and prolonged drought during 2005/06 negatively affected the economy, and the GDP has been gradually recovering to reach 7.4% in 2008.

    This paper analyses costs and benefits of planting trees on marginal lands across forestry zones in Ukraine with the purpose of using them for timber production, erosion prevention and climate change mitigation. The research reveals that establishment of new forests to increase timber production and alleviate soil erosion is economically and environmentally justified in some regions. Incorporating the effects of afforestation through on climate change mitigation increases social benefits.

    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.

    This study develops and uses a programming model for farm-level resource use and output supply response to estimate the effects of agricultural land tax in South Africa: A case study of Free State, a region of extremely large commercial farms that gainedtheir size and economic heft during the apartheid years of aggressive subsidies, favorable tax treatment, lucrative state grants and gifts, and all manner of financial assistance. The resultsindicate that changes in land use and output supply are marginal. The highest effects areobserved on irrigated farming.

    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.

    By means correlation and simple and multiple regression analysis, in this experiment were studied the correlation coefficients among the objective and subjective variables of the carcass and the relations between the weight of the main carcass cuts and the carcass weight. The carcass weight accounted for 55-93% of the variation of weight de the different carcass cuts.
