  • Success and cost effectiveness of multi-species projects

    Cullen, R.; Hughey, K. F. D.; Moran, E.

    Conference item
    Lincoln University

    Species loss is widely recognised as one of the most seriousenvironmental problems nations face. Of 142 nations compared against a wide variety of indicatorsNew Zealand is considered to be performing worst in terms ofbiodiversity (World Economic Forum 2002). New Zealand is reported to have 1300 threatened andendangered species of which about 34 species have 'recovery plans', someoperating since at least 1987. Biodiversity strategy projects estimate approx NZ $1 billion in additional expenditure on biodiversity programsover the next 20 years. There are some obvious challenges and a need to develop methodologies to aid investment decision-making and evaluate the programs and projects.

  • Earthquake forum: regaining solid ground - urban design and recovery

    Challenger, N.

    Conference item
    Lincoln University

    The University of Canterbury held its inaugural Earthquake Forum on the 2nd September 2011. It was an opportunity to hear the diversity of earthquake-related research currently being undertaken in Canterbury and a chance for researchers and those working on the recovery to identify further areas where the research can support the recovery effort.The morning consisted of presentations showcasing the breadth of research currently underway and the afternoon will create the opportunity for people to connect in a series of concurrent workshops on the land, buildings and people. Neil Challenger's presentation covers landscape architecture, temporary landscapes, exploration of design ideas and specific student research related to urban design and earthquake recovery.

  • Valuing indigenous biodiversity

    Kerr, G. N.; Sharp, B. M. H.

    Conference item
    Lincoln University

    The primary objective of the project is to create a method that can be applied by Biosecurity New Zealand (BNZ) to rapidly and accurately evaluate and rank projects aimed at protecting indigenous biodiversity from incursions of exotic pests and diseases. This presentation focusses on case study summaries of wilding pines and wasps, investigating better protection of indigenous biodiversity based on decisions supported by economic quantification of costs and benefits.

  • Legumes for hill country

    Moot, D. J.

    Conference item
    Lincoln University

    In drought prone hill country, legumes can be introduced to increase nitrogen transfer to companion grasses which increases both the quality and quantity of feed available for grazing livestock. This powerpoint presentation accompanied an oral presentation by Professor Derrick Moot in Wairoa. Topics covered included species selection, and livestock and grazing management practices to aid establishment and ensure persistence. References are included.

  • Dryand pastures - agronomy and grazing management

    Moot, D. J.

    Conference item
    Lincoln University

    This presentation explains the agronomy, growth and development of a range of pasture species used in dryland pastoral systems in New Zealand. It shows the effects of temperature, water and fertilisers on productivity and persistence. Pasture establishment, seasonal grazing management requirements, animal health and liveweight production are discussed. This powerpoint presentation accompanied an oral presentation by Professor Derrick Moot in October 2011. References are included.

  • Groundwater models

    Bidwell, V. J.

    Conference item
    Lincoln University

    This presentation introduces model concepts and terms, demonstrates some models, develops critical awareness of modelling issues, and enables use of published and accepted groundwater models. The regional scale, steady-flow, groundwater model demonstrates the principal behaviour of nitrate contamination from land use, while the stream function approach to contaminant transport addresses questions about response times of effects of land use change. The use of a steady-flow groundwater model for regional scale reduces computation time, which may be important for real-time stakeholder participation.

  • Ranking NZ river values: application of the River Values Assessment System (RiVAS)

    Baker, M.-A.; Hughey, K. F. D.

    Conference item
    Lincoln University

    Many attempts over several decades have been made to develop priority lists of important rivers for different values (e.g., angling, kayaking, irrigation, native birds) in New Zealand. Apart from one or two of these most have lacked clear methods, have been data poor, have been ad hoc, and perhaps worst of all, have not been standardised to provide a method that could be applied to all values. The River Values Assessment System (RiVAS) is a multi criteria analysis based tool that enables any set of rivers to be prioritised for any specified value.

  • The eigenstructure representation of groundwater dynamics, as a precursor for aquifer management

    Bidwell, V. J.

    Conference item
    Lincoln University

    Increasing abstraction of groundwater for irrigated agriculture on the Central Canterbury Plains of New Zealand has environmental effects on surface waters connected to the aquifers. There is a requirement by the regulatory authorities for design of robust rules, acceptable to the agricultural industry, for management of the groundwater resource. The aquifers constitute a 2300 km2 distributed system of stored water that responds dynamically to climatically-driven recharge and pumped abstraction. This system can be mathematically described by the eigenvalues and eigenfunctions of the groundwater flow equation. The equivalent continuous-time, discrete-space numerical groundwater models can also be represented in modal (eigenstructure) state-space format. This format forms the basis for design of system control. A simplification for practical control design is achieved by application of analytical solutions for the eigenstructure of groundwater dynamics for simple aquifers. These solutions enable spreadsheet-based computation and presentation of control options for public debate.

  • The theoretical relevance of an updated Marxian theory of commodity in economics

    Ahumada, Pablo E.

    Conference item
    Lincoln University

    How does material production become socially recognised in Capitalist production? Capitalism breaks down the immediate unity of the material and social moments of production, characteristic of previous modes, into two interlocked yet autonomous spheres: material production and market exchange. Commodity, its basic unit, renders production global and atomistic for the first time in history, with material production taking place in social isolation; that is, privately and independently.This paper analyses why the above fundamental question is unanswerable in Classical Political Economy and Neo-Classical Economics; the former being unilaterally focussed on material production and the latter on the market. It also assesses Marx’s attempted account of the differentiated unity characterising commodity production. That is, private work becomes objective social labour as the substance of the value of commodities, and social labour finds its necessary expression in the money-form of commodities. The paper concludes by highlighting the gaps in Marx’s economic argument.
