For my sustainable systems class, we had to find a solution to a problem. Our market was the farmers in California. Problem to solve was that they don’t get enough water for their land due to the drought.

California is one of only five agricultural regions in the world that has a Mediterranean growing climate, producing over 400 commodities, more than any other state in the nation. California agricultural production was valued at $46.7 billion in 2016 , accounting for 17.3% of total U.S. agricultural output.

The agriculture value chain accounts for nearly 3 million jobs in California.

California’s drought is expected to result in a 6.6 million acre-foot reduction in surface water.

List of crops grown in Central Valley:

1. Almonds               2. Apples

3. Artichokes            4. Avocados

5. Grapes                  6. Garlic

Solution :

Plants absorb ¼ of the total water used for irrigation. Left over water is absorbed by the soil.

Roots of plants for example, almond, garlic, corn etc. is on an average one to two feet long.

To dig and plant a Reinforced Polyethylene Liner, three-feet below the crop on a slope.

Reinforced Polyethylene Liners are :

1. Easy to Use                           2. Plant safe

3. Tear and puncture resistant   4. UV stabilised for long life

5. Inherent hydrocarbon and chemical resistance

6. Flexible and waterproof

The extra water during irrigation will be absorbed by the soil reaching down to the Reinforced Polyethylene layer.

Due to the sloped surface, the water will flow down to the end of the ground where it will be collected in  a water tank.

This water can then we reused for irrigation purposes.
