Pressure and Release (PAR) model, part 1

Along with now graduated Dr. Nasif Ahsan, I was invited to give a lecture to our new M.Sc. students as part of the course "Basic Concepts of Integrated Flood Risk management (IFRM)". This part of the course centers around the Pressure and Release (PAR) model, as developed by Ben Wisner, Piers Blaikie, Terry Cannon, and Ian Davis in their publication "At Risk: natural hazards, people’s vulnerability and disasters" (Routledge, London & NY, 2004). 

The concept behind the PAR model is that disasters occurs when societal vulnerability coincides with (natural) hazards.The only way to reduce risk is reduction of vulnerability, rather than the hazard itself. This concept is explained in the images below.

For the lecture we each focused on how the PAR model could be applied to our home countries, Bangladesh and the Netherlands. I added an interactive component in which the students developed their own version of the PAR model for floods in the Netherlands.
