Not necessarily. Some countries don't rely on rivers and lakes as much because they have other water sources like groundwater. With technology like desalination, countries can get fresh water from the sea, so they don't need rivers and lakes as much. Also, with urbanization, people don't use rivers and lakes directly as much as before. There are also other ways to transport goods, so waterways aren't as important. Plus, environmental concerns can limit how much we use rivers and lakes for economic activities.

Not all countries find rivers and lakes to be of paramount importance. Some nations have shifted their reliance to alternative water sources such as groundwater. With advancements in desalination technology, countries can now efficiently convert seawater into fresh water, reducing dependence on traditional freshwater bodies. Urbanization has also led to a decreased direct use of rivers and lakes. Additionally, modern transportation methods have lessened the reliance on waterways for trade. Environmental concerns further restrict the extent to which rivers and lakes can be utilized for economic purposes, making them less critical in some contexts.
