Transcript

  • 1. Zhenghong Tang, Ph.DUniversity of Nebraska-LincolnNorth Central Climate Science CenterFort Collins, Colorado04-05-2013Planning for Climate Change:A Planner’s Perspective
  • 2. Outlines• Research Questions• Geographic Scope• Methods• Policy Implications
  • 3. Research Questions1. Climate Impacts for Playa Wetlands: How to prioritize playawetland conversation programs under climate change scenarios?2. Planning for Uncertainty: How well did U.S. state and local plansprepare for climate change and extreme events (drought)?3. Citizen Science: How to promote citizen engagement for climatechange through Volunteered Geographic Information (VGI)?
  • 4. Research Question 1Climate Impacts for Playa Wetlands: How to prioritize playawetland conversation programs under climate change scenarios?(Where is a good place to install the pumping stations for wetlands?)• Geographic Scope: Nebraska 21 Counties (Rainwater Basin Area)• Methods: LiDAR technology & Geospatial simulation modelTang, Z., X. Li, Zhao, N., Li, R., Harvey, F.E., 2012, Developing A RestorableWetland Index for the Rainwater Basin Wetlands in South-Central Nebraska: AMulti-Criteria Spatial Analysis, Wetlands, 32:975–984.
  • 5. Rainwater Basin WetlandsPlaya wetlands in the Rainwater Basin provide criticalhabitats for 12 million migratory waterfowls to rest and feed.
  • 6. Playas are very vulnerable to climate change.
  • 7. How to prioritize conservation programsunder climate change?
  • 8. LiDAR TechnologyLightDetectionAndRangingVertical Accuracy- LiDAR : 15 cm- USGS 10*10m NED : 1-3 mHorizontal Accuracy- LiDAR : 1 m- USGS 10*10m NED : 7-15 m
  • 9. Footprint No: 10015 in Butler CountyFunctional…. but changing….
  • 10. Multi-criteria Restorable Wetland IndexVegetation TypesSoil TypesPotential water releasingDepression StatusHabitat ConditionData Source: RWB vegetation layer; Score Scale: 0.5-1.0;Measurement: Hydric vegetation in each footprint;Justification: Restoration priorities should be given to the footprint withhigher percentages of hydro vegetation.Data Source: SSURGO soil data layer; Score Scale: 0.5-1.0;Measurement: Hydro soil types in each footprint;Justification: Restoration priorities should be given to the footprint withrelatively wetter soil types.Data Source: Pits volume final 2010; Score Scale: 0.5-1.0;Measurement: Pit’s water volume in each footprint;Justification: Restoration priorities should be given to the footprint withlarger water volumes from modified pits.Data Source: Depression layer; Score Scale: 0.5-1.0;Measurement: Depressional land in each footprintJustification: Restoration priorities should be given to the footprint withlower topographical depression land areas.Data Source: AHS data layer; Score Scale: 0.5-1.0;Measurement: by frequency, percentage of functional area in afootprint, and absolute areas, by HAS in any year of 2004-2009 period;Justification: Restoration priorities should be given to the footprint withrelatively functioning habitat conditions in terms of the frequency,areas, and percentages.
  • 11. 8,875(75.5%)1,792(15.2%)901(7.7%)192(1.6%)Restorable Wetland Index (RWI)By number of footprints (and percentage)RWI: 2.5-3.0 (Lowrestoration potential)RWI: 3.1-3.5(Medium-lowrestoration potential)RWI: 3.6-4.0(Medium-highrestoration potential)RWI: 4.1-5.0 (Highrestoration potential)
  • 12. 8,208(69.8%)2,891(24.6%)322(2.7%)339(2.9%)Rainwater Basin Wetland Function Conditions in theAnnual Habitat SurveyNon-functional acres(0% )Medium-lowfunctional acres (0-50% )Medium-highfunctional acres (51-75% )High functional acres(>75%)
  • 13.  It provides a scientific ranking system forfederal/state/local wetland managers (USFWS, USDA-NRCS, USGS, NGPC, NDEQ) to implement the futurewetland conservation programs. It provides measurable evidence for Nebraska’s WetlandProgram Plan in implementing full hydrologicrestorations for wetlands.Policy Implications
  • 14. Research Question 2:1. Planning for Uncertainty: How well did U.S. state and localplans prepare for climate change and extreme events (drought)?Tang, Z., Brody, S.D., Quinn, C., Chang, L., Wei, T., 2010, Moving from Agendato Action: Evaluating Local Climate Change Action Plans, Journal ofEnvironmental Planning and Management 53(1): 43-62.Fu, X, Tang, Z., 2013, Planning for Drought-Resilient Communities: AnEvaluation of Local Comprehensive Plans in the Fastest Growing Counties in theU.S., Cities (10.1016/j.cities.2013.03.001)• Geographic Scope: National Study (including the north central region)• Methods: Content Analysis & Plan Evaluation Protocol
  • 15. Policy Implications:Local climate change action plans:High level of “awareness”,Moderate “analysis capabilities”Relatively limited “action approaches”Focus predominantly on the built environment(e.g. energy, transportation, wastes, and buildings)Pay little attention to the natural environment(e.g. ecosystem, agriculture, rural lands)
  • 16. Land Use Planning for Extreme Event (Drought)
  • 17. Land Use Planning for Extreme Event (Drought)
  • 18. State Planning for Extreme Event (Drought)
  • 19. Components aNumber ofindicators Minimum Maximum Mean Std. Dev.1. Hazard Analysis 6 0.0 10.0 4.8 2.481. Vulnerability Analysis 8 0.0 10.0 5.4 2.181.

  • 20. Policy Implications:Local/State Drought Planning:Limited awareness and preparedness for water shortages and droughtFail to integrate drought mitigation/adaptation strategies into theirlong-term development plansTypically address emergency responses wellGenerally weak in adaptation, involvement, implementation
  • 21. Research Question 3:Citizen Science: How to promote citizen engagement for climatechange through Volunteered Geographic Information (VGI)?• Geographic Scope: Nebraska & National• Methods: VGI (Similar idea like “COCORAHS”, but in mobile platform)
  • 22. Green Infrastructure My Rain Barrels My Rain GardensPlanning in a Geospatially Mobile-Enabled Society
  • 23. Low Impact Development Atlas (Web-Mapping)http://web.uri.edu/riss/lid/lid-map/
  • 24.  VGI empowered by GPS-enabled electronic mobiledevices and location-aware social media/networks is animportant approach to monitor/report climatevulnerability and adaptation practices. It is still a challenge to link the technologies and citizeninterests.Policy Implications
  • 25. (1) A Baseline-Tracking-Evaluation Database:Evaluate existing governmental plans/documentsin this region to build a baseline database totrack/compare future efforts in climate change(2) A Crowdsourcing Climate Adaptation AtlasUse mobile-based VGI platform to build an atlas forcitizens/stakeholders in climate change vulnerabilityassessment and adaptation implementationPotential Collaborations
