 The whole topic particularly in Japan also in Asia generally is the development of cities and how cities interact with water systems and whether they are the piped water systems but also the natural water systems, how do we use sponge cities for example, so how do we use natural systems to actually help provide services both for the humans but also for the environment and that's going to be a key area that we're definitely going to have some workshops and even we're talking about a whole stream for a whole day that is actually going to focus on how do we optimally connect the water systems within the city to actually enable the livability, the resilience and ultimately the productivity of the cities in the future. One of the avenues that we've been exploring is what's the best integration and it's not whether or not you have centralized or decentralized system but what's the best integration of centralized and decentralized solutions in a city space for example because some elements you can do better in a central way, some elements will be better off doing in a decentralized way. One of the key areas of this congress is going to be the digital economy or internet of things and what we're looking for there is particularly how and where do we take advantage of those developments and how can we influence them in a positive way so they're actually providing some really good support and new opportunities and new solutions for the water industry in particular in conjunction with everyone else. I believe and I've seen it from my own experience we cannot get the best solution for any one problem if every one of the professional groups or disciplines works in isolation and works out to the best possible knowledge the best solution for their area. In disaster management whether that's earthquakes whether it's tsunamis whether it's even volcanic activities so there is a real expertise here that is actually very valuable for others to know about and share so we definitely have a strong focus in this space. IWA is a great platform a great network of a whole lot of professions in a whole lot of discipline areas and a whole lot of different backgrounds experiences and obviously geographic distribution as well.
