2.1 Short description of the Technology

Definition of the Technology:

Plastic tanks of 50 to 100 liters of water with taps are placed on high platforms. Perforated plastic tubes allow water to flow and drip irrigate vegetable patches. Home gardening, once established can be carried out throughout the year.

2.2 Detailed description of the Technology

Description:

Home garden irrigation is a commonly used practice promoted by farmers in Northern Uganda. It allows involving watering of home gardens during periods of unreliable rainfall. To implement this technology, the land user was first trained by the International Institute for Rural Reconstruction ( IIRR ) which provided the initial training to farmers as part of a campaign to promote adaptation to climate change.

50 to 100 liters tanks with taps were placed on a raised platforms. Perforated plastic tubes allow water to flow and drip irrigate vegetable patches.

A water source is needed in order for the irrigation processes to take place. Hence water is pumped by a tredle pump into the plastic tanks. Perforated plastic tubes help to direct water to the gardens grown within the land users plots. In terms of maintenance, the water tank should be cleaned every month so that only uncontaminated water is used for irrigation purposes. Home gardening can be carried out throughout the year if there is enough water available.

With this technology, the most significant costs occur during the establishment phase for the procurement of water tanks. Important to note with this technology as testified by the land user, is that the high cost of water is the most important factor during the hot and dry season while maintenance costs are low once established in the medium and long term thus making the technology good for scaling.
