The tubing is usually buried under the soil or mulch to minimize evaporation losses and protect it from damage by animals.

The water is then released slowly through emitters spaced along the tubing, which deliver a precise amount of water directly to the plant roots.

The water drips slowly onto the soil, saturating the root zone of the plant and minimizing water wastage.

Surface drip irrigation is widely used in countries such as Egypt, Sudan, and Ethiopia, where water resources are limited, and arable land is scarce.

Bucket irrigation is efficient in minimizing water wastage, as the water is directed to the root zone of the plant, reducing evaporation and runoff.

#5. Treadle Pump Irrigation

Treadle pump irrigation is a low-cost drip irrigation system commonly used in countries such as Malawi, Zambia, and Zimbabwe.

This system involves the use of foot-operated pumps to extract water from shallow wells or rivers, which is then delivered to plants using drip lines.

Treadle pump irrigation is efficient in water distribution and can significantly increase crop yields, especially in areas where water resources are scarce.

#6. Inline Drip Irrigation

Inline drip irrigation is a type of drip irrigation system where the emitters are located inside the tubing. The tubing is usually buried under the soil, and the emitters release water directly into the soil through small holes in the tubing.

This type of system is less prone to clogging than other types of drip irrigation systems and is useful for areas with poor water quality or high levels of sediment.

Some African countries that have been known to adopt inline drip irrigation systems include Egypt, Ethiopia, Kenya, Morocco, South Africa, Sudan, Tanzania, Tunisia, and Uganda.
