  1. Doing Ecosystem Science at the Right Scale Dave Raffaelli Director of BESS Biodiversity & Ecosystem Service Sustainability

  2. Ecosystem services are generated at landscapes scales Managing landscapes for services means making decisions under uncertainty

  3. Choices mean trade-offs • Decisions have long-term implications. • Avoid closing down future options. • Sufficient evidence base? • No - too much uncertainty. ?

  4. Sources of uncertainty • Uncertainty in processes • what is the relationship between biodiversity and ecosystem services? • Are there critical levels of biodiversity? Uncertainty about futures • how will biodiversity respond to climate change, land-use change? Uncertainty in human behaviour • how will people respond to management?

  5. Sources of uncertainty Are the answers to these questions scale-dependent? • Uncertainty in processes • what is the relationship between biodiversity and ecosystem services? • Are there critical levels of biodiversity? Uncertainty about futures • how will biodiversity respond to climate change, land-use change? Uncertainty in human behaviour • how will people respond to management?

  6. Why scale matters

  7. Biodiversity research

  8. Societal interest Biodiversity research

  9. Research at landscape scales •Experimental and control plots in matched pairs •Challenging to achieve Vyrnwy Project: UKPopNet and RSPB

  10. Can we scale up? Measuring carbon flux at different scales

  11. The BESS Programme 1. Relationship between biodiversity and ecosystem services? Ecosystem services Biodiversity ? stock ? flows

  12. The BESS Programme Food security Climate change Biofuels 2. How will this change? Ecosystem services Biodiversity ? stock ? flows

  13. The BESS Programme Food security Climate change Biofuels 3. Is service delivery sustainable? Ecosystem services Biodiversity ? stock ? flows Novel tools for measuring stocks and flows

  14. How the BESS Programme will work • £13M NERC programme • Feb 2011 - Jan 2017 • AO in Spring, grants awarded later in year, to start early 2012 • £9M in the first tranche • Awards up to £3M • Representation of early career researchers • Focus: • Landscape science (all scales; most of Biodiversity Theme could be accommodated) • Systems under pressure and rapid change • Inter-disciplinary
