Presentation Transcript

  1. An Adaptive ManagementModel for the Red River Basin of the North

  2. Adaptive Management

  3. Elements of Adaptive Management

  4. Workshop Sequence

  5. Bounding the Problem • Actions Human activities and inputs we are interested in manipulating – the “levers” • Indicators Critical system outputs that we will use to assess the effects of actions • Driving Variables Factors external to system such as weather, commodity prices • Space Extent and resolution • Time Extent and resolution

  6. Adaptive Management Models • Dynamic simulation models (not optimizations) • Intended to understand system dynamics not generate detailed predictions. • Interdisciplinary – look at interactions between hydrology, agriculture, crop diseases etc. • Policy relevant • “Aids to thinking” - Explore alternative hypotheses and scenarios • What if …Climate change, policy change, etc.

  7. The Red River Basin of the North

  8. Study area (Ecoregions)

  9. Red River Basin (~125,000 km2)

  10. THEN NOW

  11. Digital Elevation Model data

  12. Population estimates for the Red River Basin on a 1 km2 grid

  13. 1997 Red River Flooding

  14. 1997 Flooding at Grand Forks

  15. Flood and Fire Damage at Grand Forks

  16. St Vincent in 1997 Flood

  17. Commodity Price Trends

  18. North Dakota Census Data

  19. Red River Basin Model

  20. Broad Project Objectives • To distill from the multiplicity of causal factors a simple systems model that can be used to explore the natural, economic and social dynamics observed in the Red River Basin. • To use the model to explore alternative policies with stakeholders and decision makers

  21. Issues to explore with model • Land use interactions with hydrology. • Impacts of policies, incentive programs etc. • Crop diseases in response to cropping patterns. • Feasibility of alternate crops and crop rotations. • Water quality issues. • Impacts of climate change. • Land use interactions with wildlife.

  22. Detailed Objectives of first Phase • Explore initial sub models for: • Farm economics • Crop diseases • Crop production • Driving weather/climate variables • Hydrology routine to generate inputs to other models • Etc … • Framework for linking sub-models at the basin level. • Initial compilation of datasets at the basin level. • Plan for continued of model development and analysis.

  23. Conceptual Model

  25. Styles of Modelling

  26. Current Model Status

  27. Hydrologic Units

  28. STATSGO and CANSIS Soils data

  31. Ecoregions relevant to the Red River Basin

  32. Locations of centers of VEMAP weather cells

  33. Spatial Representation

  34. Nested Time Steps

  35. Implementation Model developed for Windows PC Visual Basic Microsoft Access Uses ArcView 3.2 at present for mapping Uses Excel for chart and tabular output

  36. Running the Model Various run time options Weather data options Can vary scope of model Critical to manage indicators …

  37. Viewing outputs Multiple saved scenarios Indicators at various time steps and spatial resolutions View maps at a time View charts/tables for one or more spatial units or indicators

  38. Hydrology Sub-model • Initial model implemented • Penman Monteith Equation • Some model analysis completed • Model has not yet been refined based on observations
