Regarding salination: Any irrigation system that applies regular water where the land is not periodically rinsed by flooding will have salination problems due to evaporation. Distilled water contains no salt or minerals, but is expensive to make. Many traditional societies prevent the problem by farming floodplains, which are regularly rinsed by floodwaters but can be easily irrigated by their adjacent waterway during the dry season.
