“HIGHLIGHTS:
• Defining Essential Variables (EVs) to describe the global socio-ecological system.
• Setting the objectives of a new Group on Earth Observation (GEO) community activity on EVs.
• Defining criteria for selecting EVs.
• Demonstrating a fully functional workflow on land degradation.
• Presenting a new vision for the mainstreaming of EVs in science-policy interfaces..."

People often interpret Ashby’s Law (after W. Ross Ashby) as if the system’s internal states must have the same level of variety as its environment in order to survive, which implies that the system should be able to respond (react) to every little disturbance from the environment.

This is not completely true because, on the lowest, #regulation, level, the system blocks #variety from an (environmental) #disturbance reaching the (internal, system protected) #EssentialVariables in two ways:

1️⃣ #Passive isolation (sheltering) from most environmental disturbances, and

2️⃣ #Active reaction to (parring with) the remaining disturbance that managed to break through this passive protection.
