Ecosystem services issues
Ecosystem Services: Issues decisions

  • Uneven/no consideration in policy, planning, and resource management, including land-use planning

  • Receiving increasing emphasis given concerns over long-term sustainability of human society

  • Appealing in concept but challenging to implement in practice, especially when little or nothing is known about them


Key questions
Key Questions decisions

  • What is the current state of ecosystem services in New Zealand? How have they fared historically?

  • In the future how will changes in land use affect ecosystem services? Conversely how will changes in ecosystem services influence land-use decisions?

  • How can better knowledge about the states and trends of ecosystem services be incorporated into policy, planning and resource management?


Key questions1
Key Questions decisions

  • What is the current state of ecosystem services in New Zealand and how have they fared historically?

  • In the future how will changes in land use affect ecosystem services and, conversely, how will changes in ecosystem services influence land-use decisions?

  • How can better knowledge about the states and trends of ecosystem services be incorporated into policy, planning and resource management?

Important Note

Our values and policies will influence our knowledge of ecosystem services by influencing what information and data we decide to collect or not to collect.

    • Current state and recent trends

    • Future trends

    • Integration into policy, planning, and resource management (covered in Suzie Greenhalgh’s talk)

Characterising state trends
Characterising State & Trends decisions

  • Using the Millennium Ecosystem Assessment framework as astarting point

  • Taking a tiered approach to ES characterisation to reflect the varying levels of knowledge about differentservices

Exploring future states
Exploring Future States decisions

  • Approach

    • Multi-scale spatially-explicit systems modelling

    • National extent within a global context

    • Fine resolution (1 ha or less)

    • 100-year time horizon

  • Future Drivers & Trends

    • Population

    • Climate Change

    • Energy & Natural Resources

    • Economic Development

    • Societal Trends

    • Technology & Innovation


Land systems modelling
Land Systems Modelling decisions

  • Aims to overcome some limitations of typical land-use/land-cover change modelling

    • Confounding of land cover and land use

    • Single cover/use at any one place

    • Simple characterisations (e.g., dairy, urban, conservation)

    • Same model for different processes

  • Help explore

    • Triggers and threshold of change

    • Cumulative effects – positive and negative

    • Shocks from rare but significant events

  • Provide the ability ask more meaningful questions from a policy, planning, and resource management perspective

Land Systems Modelling Appraoch decisions

  • Advantages

    • Scalability

    • Processes operate at their own inherent scales

    • Able to address multiple outcomes, questions, and issues (e.g., multiple land use)

  • Disadvantages

    • Data hungry – how feasible is it really?

    • How much do we know about complexity & dynamics?

    • What is the appropriate level of characterisation?Is complex necessarily better than simple?


Integration into policy planning and resource management
Integration into Policy, Planning, and Resource Management decisions

  • Models and approaches to improve characterisation of ecosystem services

  • Tools to explore the consequences of different land-use planning scenarios on ecosystem services (and vice-versa)
