there is a tendency to waste. And in Bangladesh or in developing country, a huge number of people, they would be not that rich to afford it. So the government would be giving them a massive amount of water in total. And if everybody wastes just a little or the majority of the people waste just a little, that's a huge amount of water being wasted., because it's free and just because it's free people do not evaluate that much. So I was thinking that how do we make a mechanism to stop that? Is there any mechanism at all? So that was my question. Yeah, I think that in terms of IWRM, principle, the mechanism is there. So we need to, yeah, place a price on the water and yeah, on equity basis, the price could be different for different group of people and that that can help efficiency of water use and that that is kind of demand side management of water resources that is needed for yeah increasing water use efficiency. So yeah, the mechanism is there in terms of theoretical aspect, but for implementing in Bangladesh or any specific countries is, yeah, there are problems. So maybe now we can discuss water energy and food nexus. The still any food. So water energy and food nexus. This is another important paradigm of water resources management. Sometimes it's called separate paradigm, but sometimes it's within integrated water resources management, where the integration was vague in the IWRM. And in this case, this sectoral integration is explicitly mentioned, like integration of water energy and food. But it could be also water energy food climate
