8. Drip Irrigation Systems

Though primitive drip irrigation has been used since ancient times, modern techniques are rooted in Israeli innovation. Germany began developing drip irrigation systems in 1860 by experimenting with subsurface clay pipes. In the 1920s, those pipes became perforated, allowing water to drip out. Distribution of water was later developed in Australia by Hannis Thill.

But it was Israel that solved the problem of tiny drip irrigation holes getting clogged by particles in the water. Israeli Simcha Blass and his son Yeshayahu invented a plastic emitter that releases water through larger passageways by using velocity to slow the flow of water. Blass established the first experimental system of this type in 1959, and then partnered with Kibbutz Hatzerim to create an irrigation company called Netafim, which continues to thrive today.
