In June, I will be presenting work based on my dissertation research at two conferences.  The first is the International Society for Industrial Ecology conference “Science, Systems, and Sustainability” at UC Berkeley for the second week of June.  The second is the 19th International Input-Output Association conference in Alexandria, Virginia for the third week of June.  In Berkeley I will be discussing the treatment of water as a component of global geophysical and economic models.  In Virginia I will be discussing the challenges of maintaining a consistent input output database when adapting it for scenario analysis using economic and physical data from multiple sources.
