The treeflap macro

I occasionally get an email seeking an old excel macro that I wrote (back when I knew a lot less about such things, and frankly, I still don’t know very much) called treeflap.xls. It is referenced in this paper: Rees, G. N., Baldwin, D. S., Watson, G. O., Perryman, S.,…

The economics of water supply in Melbourne

This article by Kenneth Davidson cites some disturbing numbers on the extent to which Melbourne Water’s budget has become dominated by paying off of the desalination plant sitting idle 100 km south-east of Melbourne.  The arguments that Davidson makes concerning Melbourne’s plentiful supply of water running off the metropolitan area are…

Environmental Benefit Calculator resurrected

I posted a new beta version of the Environmental Benefit Calculator on urbanstreams.net today.  The R package ‘Shiny’ has made the rewrite remarkably easy (and yet it has taken me forever).  I still need to ‘prettify’ the page, but it seems to be mostly functional – doing all of the…

One small step for urbanstreams.net for Christmas 2013

Finally, urbanstreams.net is on-line full-time after a long frustrating search for the cause of the server’s random rebooting problem.  The multitude of websites out there that advise on random rebooting problems suggest numerous possibilities, but I didn’t find a pointer to what turned out to be my problem: a faulty…
