Introduction property value
Introduction- Property Value

  • How are other researchers evaluating stacked ecosystem services?

    • Payments for Ecosystem Services


Introduction property value1
Introduction- Property Value

  • How are we evaluating stacked ecosystem services?

    • Property Value vs. Stacked Ecosystem Service Value

      • Stack One: Nutrient Retention, Carbon Sequestration, Pollination

      • Stack Two: Carbon Storage, Water Runoff

    • In an area with rapid development and increasingly high land values, will the value of stacked services be able to compete?

    • Is there potential for creating markets for carbon storage and water runoff?


Study site
Study Site

  • Upper Neuse River Basin, Central North Carolina

    • Current Population = 190,000

    • Projected Population in 2025 = 280,000

Property value methods
Property Value Methods

  • Property Value

    • Taken from Triangle Land Conservancy

    • Convert Property Value to $/900 sq-m (30 meter resolution)

    • 20 year values


Property value methods1
Property Value Methods

  • Division of Quantiles

    • Property value ($) divided by stacked ecosystem service value ($)

    • Order of Magnitude

    • No Data

      • Ecosystem Service Value is 0

      • No data on property value: Govt. Owned Sites


Nutrient retention methods
Nutrient Retention Methods

  • Nitrogen Loading Caps

    • NCAC 15A Rule .0234 and .0279.Rule .0234 (6) (A)

  • Cost

    • NC DENR/DWQ WARMF Report

    • Estimates nitrogen offset rate of $44/lb of nitrogen

      • Translates to $97/kg for a 20 year period at 1% discount rate*


Water runoff methods
Water Runoff Methods

  • InVEST Water Yield Model

    • Convert all agricultural and forest land cover/land use data to urban

    • Assume change in water yield is the run-off expected

  • Costs of storm-water BMP’s for Upper Neuse River Basin

    • Substituted values for study performed in Mecklenburg County, NC (American Forests, 2010)

    • Unit cost of $2-6/cubic ft to mitigate additional storm-water runoff


Carbon methods
Carbon Methods

  • Carbon Storage

    • Output from InVEST model

    • Social Cost: $154/tCO2 (Frankhauser and Tol 1996)

    • Current European Market Cost: $74/tCO2

  • Carbon Sequestration

    • Annual NPP for each land cover in watershed at both social and middle cost

    • 20 year period with 1% discount rate


Pollination methods
Pollination Methods

  • InVEST Model Output

    • Normalize relative scale

    • Reclassify to percentiles

  • Managed Pollinator Estimate

  • Best Pollination Service Dollar Value:

    • $50 for 1 pallets, 1 acre, 1 season

    • INPUT VALUE = $300 for 2 pallets, 1 acre, year = 3 seasons

    • Convert $/acre to $/pixel at 30 meter resolution

    • 20 year value with a 1% discount rate*


Stacked es values methods
Stacked ES Values Methods

Overlay all value maps:

Areas of high dollar value for ES are lighter.


Stacked es values methods1
Stacked ES Values Methods

  • One-time ES costs

    • Carbon Storage

    • Water Runoff

  • 20-Year Value

    • Carbon Sequestration

    • Nutrient Retention

    • Pollination
