Once upon a time there were urban planners. They gave us Crawley New Town. Today, there are rural planners. They don’t call themselves that, though. Their current buzzphrase is ‘green infrastructure’. Much of their activity revolves around GIS (geographical information systems). GIS software produces attractive coloured maps that can be used for giving presentations to other rural planners. Correlations are magically transmuted into causal hypotheses. Those who live far from ‘accessible natural greenspace’ have poor health. Eureka! The SDNPA is, unsurprisingly, heavily invested in this stuff. They held a ‘Green Infrastructure Workshop’ a couple of days ago and you can find the overheads here [scroll down]. If you want to.
