Transition matrix for scenario development

[Just]

Greetings.

Please,

I have a question related to the DINAMICA EGO model simulations of changes in land use and land cover. I generated the transition matrix between two maps (2010 and 2022) and obtained the rate of change from Forest to Non-forest in my study area, with the aim of generating deforestation scenarios up to 2040. I then carried out the other stages of the model and reached the final stage (Step 10) to simulate future changes.
In the final step (Step 10 - Lesson 18 - Guide), I inserted manually modified transition matrices to generate alternative scenarios, in addition to the trend scenario. For example, in Scenario 1: project the deforestation trend observed between 2010 and 2022. In Scenario 2: reduce the transition rate from forest to non-forest by 20%. Scenario 3: increase the transition rate from forest to non-forest by 20%. In the end, 3 scenarios will be generated: trend (scenario 1); optimistic (scenario 2 (-20%)) and pessimistic (scenario 3 (+20%)).
I couldn't find any information in the manual about this type of manual modification of the matrices. Is this type of modification possible or is it not recommended? Is this type of modification and scenario plausible in the model?

Best regards,
