(3) Drip Irrigation Phase

Water Conservation Measures

• 1950s – Invented due to low cost plastics

• 1965 Netafim Co. started: Kibbutz Hatzerim.

• Today > 500 million dollars in annual sales.

• Used world-wide from marijuana growers in California to vegetables in Afghanistan.

• Voted Israel’s “best invention.”

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!!!

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).

(4) Water Reservoir Phase

Floodwater can be used for 2 purpose:

1. To improve

quality and quantity

of ground water by

replenishing and aquifers.

2. To impound

floodwaters for

direct supply to irrigation systems

in nearby fields.

Zaragoza, 30 July 2008

CONCLUSIONS

• Israel’s water managers can claim real achievements.

• Environmentally – many mistakes.

• Water subsidies are history. Privatization is the future.

• Command & Control seems to work.

• Pricing mechanisms will affect individual decisions.

• Markets are unlikely as “economic efficiency” has

never been a paramount policy objective.
