Modernizing Buried Jar Irrigation with Advanced Technologies

Irrigation using buried terracotta jars in southern Tunisia delivers water efficiently to crops through slow seepage, reducing evaporation and saving 50–70% compared to surface methods. This traditional, sustainable technique maintains soil moisture, reduces weeding, and supports higher yields in arid conditions. Used by Tunisian olive farmers, it requires careful installation and annual maintenance with rainwater and mild acid solutions to prevent clogging. Enhanced by soil moisture monitoring and modern technologies like IoT or remote sensing, the method shows promise for scaling through public-private partnerships. Research and training are recommended to address material durability and system integration. The approach, supported by INRGREF and co-funded by the EU and Swiss Confederation, offers a viable solution for water-scarce regions.
