because in Spain, it considers not the gravity irrigation, but energy driven drip irrigation systems. So if we convert the irrigation system in Egypt, then the water is saved, but at the same time, the energy and carbon dioxide production rate has increased significantly. So this kind of trade-up can be considered by considering this nexus apples. And also, I think, Jim Aver was mentioning about the biofuel. And here is the example of biofuel, how the increased consumption of biofuel is promoted as an alternative of oil and gas. But at the same time, it can create a huge amount of water scarcity and food sustainability in the United States, but also in the other countries. So the unexpected consequences can be taken into account by considering this nexus approach. So also in terms of integrated planning and decision making and governance, this order energy food nexus is very important. Let's consider the trans boundaryary aspect. So here in terms of water energy and food nexus in the trans boundary context, if you see the relation between water and food and for the food production, you must need water. And in the upstream, water uses for the agriculture can affect also in the downstream. And this can, so the water and food are highly relevant in the trans boundary context, but also food affect water resources. For example, it can through intensifying agricultural practices and land use changes by agricultural expansion, this can affect water quantity by changing the runoff
