Natural Resources, Climate Change, and Policy Workshop

- Tom Robinson, Director of Conservation, Science, and Innovation, Bay Area Open Space Council
- Carrie Schloss, Spatial Data Scientist, The Nature Conservancy

This presentation was given during a workshop at the Bay Area Greenprint Launch Event on June 21, 2017 at the David Brower Center in Berkeley, CA. More info on the Bay Area Open Space Council's blog: http://openspacecouncil.org/the-bay-area-greenprint-has-launched/

Natural Resources, Climate Change, and Policy Workshop

  1. 1. Natural Resources, Climate Change, and Policy Workshop
  2. 2. Water Resources Agriculture Recreation Biodiversity Carbon Stock
  3. 3. Habitat Connectivity
  4. 4. County habitat connectivity ordinance Linkage and connectivity profile Relatively small area yields low contributions Linkage barriers in/near your area Fish passage barriers in/near your area
  5. 5. Water Hazard Risk Reduction
  6. 6. Water Hazard Risk Reduction
  7. 7. Amounts and proportions of flood-absorbing land cover types Estimate of sea level rise inundation at 2050 and 2100 500-year floodplain as a proxy for “extreme weather events” How much coastal and flood-prone “green infrastructure” is there to attenuate flood waters and destructive flood energy?
  8. 8. City setback policy
  9. 9. Food Production
  10. 10. Benefits of Agriculture • Bay Area residents “take pride in their region and its unique quality of life, who are sympathetic with the idea of preserving family farms, and many who have embraced the idea of eating locally.” –2011 American Farmland Trust report • $2.36 Billion gross production in the Bay Area (Ag Commissioners) • 400,000 local jobs (2013 SPUR report) • Ranchers and farmers steward the majority (~2.5M acres) of our privately owned surrounding open spaces • Lost 100 square miles (2 San Franciscos) of agricultural land since 1984 Food Production
  11. 11. Morgan Hill Gilroy
  12. 12. Morgan Hill Gilroy 1984
  13. 13. Morgan Hill Gilroy 1984
  14. 14. Prime Farmland Urban and Built- Up Land Rural Residential 1984 Prime Farmland Urban and Built- Up Land Rural Residential 2014 1984 1984 1984 19842014 Morgan Hill Gilroy
  15. 15. Farmland composition of your area“94% of Prime Farmland in Santa Clara County is in my Area of Interest” Only 9% of Prime Farmland is protected in Santa Clara County Prime Farmland in my Area of Interest constitutes 6% of the Bay Area total Prime Farmland Economic benefit estimate Additional irrigation estimates Estimate of agricultural resilience Policies affecting agricultural land in your Area of Interest Only 5% of Prime Farmland in the Bay Area is permanently protected
  16. 16. Carbon Stock
  17. 17. Carbon is sequestered from the atmosphere and is stored in biomass of trees Carbon is stored in the organic matter of soils Development and tilling can release the carbon stored in soils Land use change can release above ground live carbon
  18. 18. Above-ground live carbon on natural lands Soil carbon
  19. 19. Questions?
  20. 20. Data Used for Agriculture • Ag cover – Farmland Mapping and Monitoring Program http://www.conservation.ca.gov/dlrp/fmmp • Production value – Agricultural Commissioners’ annual reports https://www.cdfa.ca.gov/exec/county/countymap/ • Land protection – Bay Area Protected Areas Database • Irrigation deficit due to climate change – ? • Fallow rates • Agricultural policies
  21. 21. Biodiversity
  22. 22. Biodiversity
  23. 23. Impervious Surface Groundwater Recharge Water Resources
  24. 24. Water Resources
  25. 25. What’s in the Greenprint? Prime Farmland Farmland of Statewide Importance Unique Farmland Farmland of Local Importance Suitable Rangeland “Best” combination of physical and chemical characteristics for the production of crops Meets strict criteria “Good” combination of physical and chemical characteristics for the production of crops Land that is important to the local economy due to its productivity or value Has been used for the production of specific high economic value crops, but does not meet Prime or Statewide criteria Land on which the existing vegetation, whether grown naturally or through management, is suitable for grazing or browsing of livestock Agriculture
  26. 26. Biodiversity What’s in the Greenprint? Conservation Lands Network: Priority Land Conservation Lands Network: Key Riparian Corridor Avian Tidal Habitat Prioritization Habitat Connectivity Hotspots of Species Requiring Compensatory Mitigation Baylands, Wetlands and Vernal Pools 1M acres of land have been protected, the CLN answers “where should the next million be?” An inventory of riparian corridors critical to the survival of anadromous fish and other aquatic life A prioritization of existing tidal habitats for 5 representative species of bird Regionally-scaled large landscape blocks and the habitat linkages to connect them, plus estimates of connectivity (from Omniscape) Areas of overlap where regulated species have their most needed habitat Wet areas are essential to terrestrial and aquatic life
  27. 27. What’s in the Greenprint? Natural Land in the Active River Area Floodplains Hydrogeologically Vulnerable Areas Recharge Runoff Drinking Water Source Watersheds Natural land cover in the active river area filters excess sediment and pollutants thereby maintaining or enhancing water quality Natural lands in flood hazard zones can help reduce flood risk for populations and agriculture downstream Natural land cover provides some protection to aquifer water quality by decreasing contaminant release and increasing groundwater recharge in these areas Recharge rates in mm/year based on a 30-year average Runoff rates in mm/year based on a 30-year average. High runoff means increased delivery of pollutants and sediment Natural lands in water supply sources deliver cleaner water at lower costs by filtering the water Water Resources
