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?

  • How different are the answers from different models?

 Where is the pollution coming from? And how do pollutants act together?

  • Are there different sources of the same pollutants?
  • Would I make a different decision if I looked at one or several pollutants?
