 This is the moment for water professionals to really take care of sustainability and resilience. Sustainability is very important in the water. You build for years and years so you need to have a vision on long term but you have also to keep the past of your knowledge. Resilience is also very important because we know with climate change that it will be more difficult than before to be able to still give a good service and for the people who don't have, we need to give and for them it will be more difficult. So I think sustainability, resilience are key words for water professionals. Of course COP23 is very important, it's the second time after Paris and for the first time last year in Morocco people spoke about water in the SDGs, they said well be careful because of climate change the water will be more difficult to deliver and I think that was very important and we still have to remember to all the people who take care of the climate change that whatever they do there will be a big impact on water. So that is the first message. We need to work on it, we need to reduce our energy but more than that we need to organize resilience in order to deliver service whatever happens. The second part is very important too is SDGs, it's different from climate change. SDGs is more we need to give people the right way of living and for that the development is key but also sustainability of our water and in economy and water has a specific goal which is I think very important because it remembers the importance of water but more than that water is everywhere in the SDGs so I think the politics and the United Nations have decided to focus and we as professionals now we have a time and we need to show that we are able to cope with that and to do it because we have solutions.
