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 planning on doing be cost-effective?
  • Can I transfer these measures or approaches to other catchments? Will they be less or more effective?

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?
