 There is a water crisis today in terms of actual water for drinking for people, for agriculture, for the livestock. And this is going more and more acute as the years pass by. This year was one of the hottest years in the US, in Argentina, in Mali, in India. You know, at one end, climate change, climate is getting hotter. And on the other side, water is becoming scarce. You know, put these things together and then you can understand that we are in a phase today of we need to really rethink, you know, where are we going to get our water? People say population is going to be 7 billion. Again, where are they going to get water for drinking, for agriculture? We have been hearing that the sustainable development goals are 17 and what is at the heart of all of them. But if you don't have water, then how will you really achieve the sustainable development goals that we are talking about? And scarcity does not only mean water scarcity in terms of quantity, but there is also a problem in terms of quality. So you could have a lot of water which is polluted either from the industries, from domestic waste, or polluted from the, you know, the natural sources like arsenic and fluoride, which means there is water, but there is not water to drink or no use for agriculture. So that is also scarcity. So it's both, it's in terms of quantity that it's happening, that is water from the rains, but also on the other side that because of our pollution and all our development pattern that we are following, we are polluting the water and therefore it is not fit for consumption. One of the way forward is how do we manage water better more wisely? How do you involve communities in managing the water? How do you get the different stakeholders, the different sectors together? It's the private sector, the public sector, the people, the research institutions together to work together of solving some of the issues that I mentioned earlier. Second is today people used to say that, you know, desalination is very expensive. But if you look from 1990 to 2017, boom, the price of desalination or the memories and the technology has come down. So you do not have to take water now from 300 kilometers to a city, you know, you can actually also, if it's a city on the, on the coast of a, a city on the coast, you can actually use desalination, which is what you're using technology, which has now become cheap. Second is reuse, you know, why do we need to, you know, get again water from hundreds of kilometers? How do you start doing local, you know, plants which treat the water and we can reuse the water? And the third is, it's also an interesting concept of, it's not only getting water from 300 kilometers. As I said, it's also the energy. So it's a mix. If you can do decentralized planning, decentralized, you know, treatment of water, you're also saving on the energy, which you would have had to get, you know, spend to get water from a long distance. And second is to produce that energy, also you need water. So if you don't have water, how would you have produced that energy? So it makes economic sense. When we talk of, you know, dealing with water scarcity, it's not only about good management practices. It's also about making good economic sense because people will say, where will the water come for these new technologies? But what experience has shown us is that if you do many of these things right, you're making economic sense, you're saving money and you can use it better than to, you know, address other issues of sanitation for all. So it's all linked as I'm trying to show you, you know, it's not only a question of scarcity, but how do we wisely manage these issues both with good policies, with good natural infrastructure being put in place, with good, as I said, technologies. So it's linking up the private public sector together with the communities. If 10 million people in Hong Kong, can you see water to flush that toilet? You can imagine the amount saved. Then why do we need to use clean, you know, drinking water which we use to flush your toilets? When those are the things, I think those are the new lyrics, you know, and to change and move ahead. And therefore, when I said it's not only about water scarcity then, we're talking about good water management. That's the basic, you know. How do you prepare and not repair? I think that's the real point.
