 I think that a lot of cities are challenged and being challenged about how they are going to solve their current issues and how they prepare for the future. There are a lot of reports stating that by 2050, there's going to be about 70% of the population moving into urban areas. So these cities need to prepare and plan and we from SAP would like to partner with these cities to make it sure that we can create prosperity and livability for the future cities. Do you have three things to do for a better quality of life in cities? Yes, we believe that there are three areas that cities currently should engage and plan to do. One area is we believe that they need to orchestrate a symphonic ecosystem in the city. There are a lot of players in the city. They can only achieve goals, sustainable development for the end users for the citizens. If they bring these players together in this year's seamless ecosystem, we also believe that with intelligent digital solutions, they can achieve prosperity and they can achieve also economic goals. And again, with database, new innovative business models, they can move towards their goals to become a future and smart city. Okay. Mr Akonina, let's talk about waste. It's not as simple as it seems at the first moment, the topic waste. Yes, so waste management is the important topic in a smart city because it's easy to understand. It's from political dimension, very easy to market for the mayor and for the city to show something, the transition to a smart city. Of course, that's only the beginning and it's a transparent beginning. And then you can do with the more experience and you can also do the challenging topics in the city and put some sensors and places that are more invisible in the city. And that's why waste management is typically selected as one of the pilot scenarios in the city and one scenario. The other one is we have now the big, big trend with sustainability and Friday for Future. And therefore people are thinking and connecting this with the private life, with the work in the city and therefore all the sustainability aspects coming into the city. And the other third point is why waste management is a very good example because you cannot incentivize the citizen always with money that doesn't work. You need to put some positive goals to the citizen so that they change, that they are moving, that they are not driving in the city center, that are changing to public transport. It's not always the money, of course, for a lot of people, but not the only part. And therefore, waste management is a big, big part. You need to incentive the people. You need to train the people that are better sorting and therefore this is a starting point. Sustainability is a starting point in general for smart cities and therefore it could be also called sustainable smart city or future city. Can you give us a concrete example for waste management in a city, how does it work in a clever way? Yes, so one example in a smart city or one transition here is, for example, city of Heidelberg, putting sensors in glass containers, that was the starting point, but in Germany a big, big trend or a big, big topic is putting sensors in all types of equipment that includes, for example, used closed containers and that have more not so stable, robust consumption. The other one are the big, big press containers that behind conference centers, behind big offices in industrial parks. So there have already the sensors and you need to use that data and also the trucks in a city in regards of snow removal could be a big, big starting point and that's what the waste management department in a city is doing. And also the experience in the restrooms or the clean city is some part. So waste baskets on the one hand side, but also the smiley buttons, what you know from the airport are a big, big part to sensor as the IoT sensor to sensor what the citizens are thinking and then improve the outcome which is a clean city. Secure safe place based on clean environment. Waste management, a very good and very important example for things to do in the smart city, but there are many, many more topics in the smart city. Can you give us some more examples? Sure. So that was a great example of a strike mentioned how we bring together IoT, sensor technology and new technology, intelligent business models and how we can really create an outcome. We worked also with several other cities, for example, Buenos Aires, we also deployed the same concept about applying IoT sensors to make it sure that when heavy rain comes that they can move citizens out of certain areas of the city. Other example, applying new technologies, for example, blockchain in the interaction with cities. So there was in south there a city said that we have so many siloed information sources and the citizen comes to our offices and they need to take care of some kind of a task or some kind of other issues that the city task, they would need to identify themselves over and over again. Instead of that, they have applied blockchain technology to have one information source from the citizens and they distributed it between all of these entities securely and up to date all the time. Thank you for joining us here. Instead, God and thank you for watching.
