Addressing salinity problem of the soil
The intrusion of seawater/brackish water inland is a problem all over the world for various reasons such as sea level raising etc The best way to address the problem is to create a barrier between the land and sea and then leach the soil with fresh water and pump out the leached brackish solution and subject to reverse osmosis and pump back the fresh water and discharge the saline water back into the sea or allow it to evaporate in a separate area.When evaporating the saline water ,make sure the water does not percolate into the soil again by using a polyethene sheet so that saline water will be evaporated leaving salt behind.This process has to be continued for weeks or months till the ground water becomes normal.
