40 Some good news: Drip Irrigation
30
End of 1950s – low cost plastics makes it possible. In 1965 Netafim Corporation established at Kibbutz Hatzerim. Today over 200 million dollars in annual sales. Used world-wide from marijuana growers in California to vegetables in Afghanistan. Israel’s 50 th anniversary: voted “best invention.”
31
Drip Irrigation: Benefits Evaporation is reduced relative to sprinklers Can irrigate steep landscapes. Eliminates drift during wastewater reuse. Allows for precise chemigation. Delivers to the root zone. Automation = optimization Water use per yield drops!!!
32
Subsurface drip irrigation: The Next Generation Conserves water while: controlling weeds, minimize runoff and evaporation, increase longevity of laterals and emitters, ease use of heavy equipment in the field, and prevent human contact with low-quality water. Labor saving (avoids seasonal installation).
33
Water Harvesting in Israel Floodwater can be used for 2 purposes: 1. To improve quality and quantity of ground water by replenishing aquifers. 2. To impound floodwaters for direct supply to irrigation systems in nearby fields.

"And now it is my turn for a terrible confession. I object to nature preservation. The very ideal of "preservation" is not acceptable in almost any area of life. We have not come into this world to protect or preserve any given thing, mitzvah, nature or cultural heritage..... We have not inherited a museum, to patiently wipe off the dust from its displays or to polish the glass..... Nature also is not a museum. One is allowed to touch, allowed to move, to draw closer, to change and to leave our stamp..... Touch the stone. Touch the animal. Touch your fellow man. On one condition. How to touch?.. To answer on one leg" and in a word I would say: 'with love. ” Amos Oz, 1981
