I've wondered about these salt evaporation ponds a lot. It's the traditional way sea salt has been harvested in Japan from the sea and also in the mountains of the Andes from mountain deposits of salt water. And it is still harvested industrially like that on some islands.

The thing I'm really curious about is this is happening on a large enough scale does it begin to affect the amount of precipitation that can occur? I'm wondering if it can be utilized to increase rainfall during times of drought

Maybe even long canals to transport the ocean water far inland in very shallow streams that are meant to be evaporated by the sun over time. This uses almost no energy on our part, produces salt, and might possibly help increase rainfall?
