Description

1.From the Wikipedia:

"Backcasting starts with defining a desirable future and then works backwards to identify policies and programs that will connect the future to the present. The fundamental question of backcasting asks: "if we want to attain a certain goal, what actions must be taken to get there?"[2][3]Forecasting is the process of predicting the future based on current trend analysis. Backcasting approaches the challenge of discussing the future from the opposite direction." (http://en.wikipedia.org/wiki/Backcasting)

"Backcasting is a straightforward idea, one which follows on naturally from the process of visioning. I’m sure it has been around for a while, but the first time I heard of it was in an excellent book “Natural Step for Communities: How Cities and Towns Can Change to Sustainable Practices” by Sarah James and Torbjorn Lahti (2004). They argue for a process which starts with visioning a desirable future and then working backwards. It is based on the question “if we want to get somewhere, what actions do we need to take in order to get there?” (http://transitionnetwork.org/patterns/getting-started/backcasting)
