Every infrastructure project causes damage – to society, to the environment. We know this. A new road means loss of green space. It disrupts existing commerce and communities. Steel and cement are toxic to the environment. We accept this damage as a necessary cost of achieving a larger community good.
For too long, we have accepted this ‘larger community good’ to be the short term jobs that are created. But as shown in the last two posts, not only is this jobs gain illusory, it causes its own damaging distortions in the economy. Construction workers might gain, but other workers lose.
So if we are to support a new infrastructure project it must be because of the greater, ongoing benefits that the infrastructure will provide – after it has been constructed. For evidence based decision making, this is where we must seek our evidence.
Not only does infrastructure damage the environment, research following the construction of the highlands highway in PNG showed it undermined people’s health.
