Systems thinking averts apocalypses now and in the future: why we should always look on the bright side of life

ABSTRACT Systems thinking and analysis from the civil and environmental engineering communities have been highly successful in mitigating the effects of natural and man-made hazards. Not surprisingly, the United Nations Human Development Index shows steady improvement for every nation since its implementation in 1990. The world has never been healthier, wealthier, or more educated than at the present. Climate change and sustainability remain as significant challenges to be faced. It will be shown, though, that economic and life-safety losses from climate change are often exaggerated and do not reflect wealth creation, human capital, and new improved technologies. There is an urgent need for systems-led approaches and there is a proud record of accomplishments in the past that should equally as well translate into the future. This paper will discuss these issues, as well as briefly describe the importance of systems engineering in dealing with new and emerging threats, as well as the political imperative. The paper will also highlight that there is much to be optimistic about the future, and in the ability of systems thinking to meet any challenges. And to quote Monty Python we should try to ‘Always Look on the Bright Side of Life’.
