All over the world a wide variety of clever solutions are implemented to overcome salinity problems. We are happy to share this salty solutions overview with you and invite you to send in your solutions to firstname.lastname@example.org.
What: All irrigation water (except rainwater) contains salt. Therefore, salinization of irrigated land is inevitable, unless it is served by a drainage system that flushes excessive water (and the salt within) away from the field.

|Aquaculture and agriculture in saline areas, Dutch experiences|
What: It is possible to breed varieties of common crops to grow in saline enviroments. Saline aquaculture refers to the cultivation of plants or animals in saline water. In the Netherlands several initiatives are carried out to explore the feasibility of this type of aquaculture which can become valuable as soils are going down (due to drainage) and the sea level is rising (due to climate change).
What: getting fresh water out of saline water using a variety of techniques, e.g. membranes, that remove salts and other minerals.

|The Bhungroo straw|
What: The Bhungroo straw is a simple technique to inject filtered storm water in to the ground. It is currently used in India, but has the potential to be implemented in other parts of the world as well.

|Infiltration ponds as buffer|
What: Infiltration ponds can be constructed into dunes to enhance natural recharge of precipitation to groundwater serving as a barrier to saline groundwater intrusion. The ponds can be excavated or formed through enclosure dikes. These ponds are already used in Atlantis, South Africa.

|Treating Saline Water by magnetic Device|
What: Passing water through a strong magnet reduces the attachment of water to saline particles for 8-10 hours. This works with water with salinity up to 2000 parts per million.

|Purify Water with Nanotechnology|
What: Nanotechnology is the manipulation of materials on a very tiny scale ‒ essentially at the atomic and molecular levels. In this case, it is used to treat brackish groundwater using nanofiltration membranes. These act as a physical barrier and selectively reject substances smaller than their pores, removing harmful pollutants and retaining useful nutrients present in water.

|Leaching of Excess Salt from the Root Zone|
What: There are many benefits to rainfall, but one in particular is the leaching of excess salts from the root zone of plants. In prolonged drought conditions, salts build up in the soil, causing several problems.
Here are a few ways to reduce soil salinity:
