It is interesting to note that Engineers Australia has declared 2011 as the Year of Humanitarian Engineering:
“a year in which we will recognise the role of engineering in improving quality of life and disaster recovery.
“Our goal is to promote the significance and importance of humanitarian engineering to both the engineering profession and wider community so that humanitarian engineering receives the necessary support in Australia and abroad – and continues to make a difference,” it said.
It seems very relevant to the work of Energy for Opportunity (EFO) – http://www.energyforopportunity.org/
