Learn about how the reintroduction of an ancient irrigation technique has proven to be one of the most sustainable and water efficient techniques available to farmers.

Ollas are clay pots used for irrigation. The clay wall is very porous, allowing small amounts of water to slowly pass through tiny holes in the Olla wall. This allows plants to continuously and slowly take in water at an ideal rate for plant growth. Roots from nearby plants are drawn to the water, and fix themselves to the pot.

They first appeared in the world's first agricultural science textbook, which dates over 2,000 years old and originates from China.

As much as innovation is important, we should remember that overlooked traditional knowledge and technologies can be just as powerful. Many argue that this is still the most sustainable and efficient form of irrigation to date.

University researchers in Lausanne, Switzerland have created a sustainable and socially minded business - 'Wepot' - using this ancient technique to reduce water use and improve irrigation efficiency in nearby swiss farms.

They also produce vegetable pot kits, which seek to enable farming and crop growing at the household level. Promoting the notion of growing your own vegetables.
