Israel is a small country, and much of it is desert. For many years, water was one of its biggest problems. So how did Israel become a world leader in growing food with very little water?
Part of the answer started with a tree. In the 1930s, an engineer named Simcha Blass noticed that one tree near a leaking pipe was much bigger than the trees around it. The pipe dripped water slowly and directly onto its roots.
Years later, Blass developed drip irrigation: thin pipes with tiny holes that give each plant exactly the water it needs, drop by drop. In 1965, he and a kibbutz in the Negev started a company to produce it.
Drip irrigation can save up to half of the water that farmers use, and it helps crops grow better. Today, farmers in more than 100 countries use it. Together with desalination — turning sea water into drinking water — it has helped Israel turn a dry land into a green one.

Drip irrigation gives each plant exactly the water it needs. השקיה בטפטוף נותנת לכל צמח בדיוק את המים שהוא צריך.
נכון או לא נכון
Only farmers in Israel use drip irrigation. רק חקלאים בישראל משתמשים בהשקיה בטפטוף.
