Khettaras
Traditional groundwater collection and conveyance systems used in the arid and semi-arid regions of Morocco, particularly in the Atlas oases. They consist of underground galleries and vertical shafts that transport water from aquifers or recharge areas to agricultural lands by gravity. They provide irrigation, water supply, and oasis conservation, representing an ancestral technology for the sustainable management of water resources in desert environments.

Sector:
They provide significant environmental benefits by enabling the sustainable use of groundwater through a gravity-fed conveyance system that reduces energy consumption and evaporation losses. They help conserve aquifers by regulating water extraction, support the preservation of oases and their associated biodiversity, and contribute to preventing soil degradation and desertification. They also strengthen community resilience to water scarcity and climate change by promoting efficient and sustainable water resource management in arid and semi-arid regions.
