How do humans cause salinization?
The most influential human-induced factors are land use, farming systems, land management and land degradation. Inappropriate irrigation practices (such as the use of salt-rich irrigation water) and insufficient drainage both cause salinisation.
How can salinization be prevented?
Solutions include improving the efficiency of irrigation channels, capturing and treating salty drainage water, setting up desalting plants, and increasing the amount of water that gets into aquifers. Mulches to save water can also be applied to crops.
