Technical FAQs 4

Can drip irrigation improve crop productivity?

The implementation of smart irrigation systems such as drip irrigation can significantly reduce the total amount of water required to produce field crops. Empirical evidence suggests that automated drip irrigation system can save 26% more water and enhance high crop productivity compared to traditional irrigation methods .

Do farmers adopt smart irrigation in Botswana?

Despite high (66%) awareness of climate-smart irrigation technology, many (52%) farmers did not adopt smart irrigation in Botswana. Age, gender, and access to credit had a statistical and negative influence on adoption. However, level of education and farming experience had a positive influence on adoption.

How does a solar drip irrigation system work?

Solar drip irrigation systems are simple and straight forward. Once introduced and setup properly, they can be extended easily. Water is distributed at low pressure (app. 1 bar/15 psi) through pipes, hoses and tapes to the water outlets, so called emission points, and leaves the conveyer by dripping.

Can a solar irrigation system boost water from a lower reservoir?

Optionally a second pump can be applied for boosting water from a lower reservoir. Any low pressure (drip) irrigation system can be used with PV pumps with proper pump layout and effectuate the most efficient crop production. Solar drip irrigation systems are simple and straight forward.
