Economy of PNG

A driver is a natural or human-­‐induced factor that directly or indirectly causes a change in the system of interest (Millennium Ecosystem Assessment 2005). Understanding drivers of change helps us to 1) identify causes and mechanisms of change in variables of interest (Biggs et al. 2011, Fereira et al. 2011), 2) be able to anticipate and sometimes even predict future outcomes, and 3) be able to understand the context or ‘backdrop’ of past change.
