Forum issues addressed by case study
How can I know if land management will be effective?
- What is the effect of different land management interventions on water quality?
- Will what I’m doing provide secondary or wider benefits in the catchment for carbon, biodiversity or other ecosystem functions?
Does it matter what data and models I use in planning /assessing catchment management? Can the answers they provide be transferred to other catchments?
- Is the answer sensitive to the quality and quantity of input data?
- Is the answer sensitive to different models?
How can I look at sensitivity / impacts on different catchment functions / services?
- Is freshwater biology more or less sensitive than chemistry?
What did we find?
This case study examines the sensitivity / uncertainty in outputs of models at various scales resulting from differences or uncertainties in models and input driving data. Three cases will be considered: A) uncertainties arising from the model structure being used; B) uncertainties arising from the data being used; and C) uncertainties arising from drivers used in future scenarios.
