Irrigating with Saline Water

Water use is a major issue in Israel due to the limited availability of fresh water. With agriculture accounting for over 50% of the country’s water use, it is vital to implement techniques that reduce both the total water usage for agriculture and the quality of water used. One way Israel does this is by irrigating with saline water. Since saline water often has negative effects on plant growth, Israel has created new varieties that can withstand the brackish water (like the Desert Sweet tomato) by grafting the bud of one variety of fruit with a salt-tolerant rootstock. Together with treated wastewater, these marginal water sources accounted for 57% of the water used for agriculture in Israel in 2011.
