This is the first presentation of the session organized by UAB and Water Footprint Network on Societal Metabolism and Water.
The session is the first seminar organized to link the topics of Societal Metabolism and Water Flows/Footprinting.

Some author have made any kind of realtion between the fulfilment of the human needs and the creation of conflicts. If we look at the concept of Scarcity it comes because the desires as highre than the resources: Two questions: How is the cycle? Is water becoming scarce?
The Study of the breakage of the cycles should be addressed in a comprehensive way
If we look at the proportion of resources we need to produce 1 ton in systems woth different wsys of production, we see that ehey differ. Water is not an isolated factor:
