but also it can affect eutrophication and salinization and affects water quality. But at the same time, if you see the relation between water and energy, for the energy production, of course, you need water. And energy production also affects water quality and quantity. For example, the hydropower production for energy affects water quality in terms of changing water temperature and also so the water temperature can change quickly by storing water in a in a dam and that can also affect changing the water quality parameter. So thus you can see that this linkages are important for trans boundary context. In this study done by the Kaskin and Etel, they try to compare three transboundary areas in the Central Asia, mainly the Aral Sea, South Asia context, Ganges, Brahmaputro, and in the Meekong region, the Meekong River Basin. And they try to qualitatively analyze this interrelation between the water energy and food and the thickness of the line can determine how the relationship established and what are the strength of the relationships are determined by the thickness of the aligned. For example, in the case of Central Asia, the impact of food on water is highly important there, but also impact of energy production on downstream water flow is also important. In the case of South Asia
