And it can immediately create institutional mismatch. And that can be managed through water diplomacy approach. So that's how I can see a relation with IWRM. So I can see auto diplomacy can be useful for the difficulties that have IWRM implementation can be somehow implemented through incorporating water diplomacy, of course. That's how I feel the relation of IWRM and order diplomacy. Do you want to go to your next slide and look at the principles of IWRM explicitly in light of the general discussion we've had. Yeah, yeah. Yeah, so these are just a historical perspective of IWRM. So according to, so it just started from the UN conference on Water in Marth del Plata in 1977, then in 1992 Dublin conference. This is the main building block for developing the IWRM principles. And in this conference, these four principles has been considered. So the principle number one is the fresh order is finite and vulnerable resources, essential to sustain life
