Unit 1.4 : Application exercise

An exercise in four steps in order to test the newly acquired knowledge. You can download the model at every step if necessary.

  1. Family farm model : step 1 – Base model (length : 45 minutes)
  2. Family farm model : step 2 – Water management policy (length : 20 minutes)
  3. Family farm model : step 3 – Loosening the water constraint (length : 20 minutes)
  4. Family farm model : step 4 – Adding a cashflow constraint (length : 20 minutes)
