2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Under groundwater is abstracted by excavating water abstraction points for livestock production.
Waterhole is excavated for abstracting underground water for watering livestock as well as irrigating crops during the dry season.

2.2 Detailed description of the Technology

Description:

Farming in rural Northern Uganda is vulnerable to climate variability and drought in particular since it overwhelmingly depends on rainfall. Thus, innovative small scale farmers there resort to underground water resources to further their agricultural and water resources are sustained naturally through recharge. The mechanism used is in accessing underground water resources is termed underground water obstruction and involves excavation of structures such as open wells, soak pits, and recharge shaft/ trenches of 2-6 m deep hole, which is manually dug from the ground to allow water to come up (see Figure below).
Underground water abstraction is done by excavating a hole in the ground to reach water underground . A 2-6 m deep hole is manually dug in the ground/ soil to allow water to collect and come up. The hole is shaped in such a way that water does not flow out, and the top is covered to keep the water in the hole protected from contamination. The opening is covered with local materials like poles, bamboo stems (Bamboo aridinarifolia), etc. Water flows into the hole through various methods of groundwater recharge such as open wells, soak pits, and recharge shaft/ trench.
The activities involved in establishing such a underground water hole include (1) identifying suitable site for digging the hole, (2) looking for trainer or expert to advise on how to dig and cover the hole, (3) looking for labor, and tools (e.g. hoes, spades, poles, etc.), (4) digging the hole to a depth of about 2-6 m, depending on the level of water table, (5) protect the hole with bamboo or wood to ensure hygiene and from people falling in.
The returns derived from this technology include: an effective alternative water source during the dry season which is used for crop irrigation (e.g. maize – Zea mays; cabbage - Brassica oleracea) and for livestock production/ watering.
This technology is most preferred because it is cheap, affordable and easy to maintain. The only costs are at the establishment phase. Its main challenge is that it can be contaminated when managed poorly. To ensure this, the farmer needs to keep in contact with the land user to ensure maximum proper management of the hole to minimise contamination.
In terms of impacts, the technology provides an effective alternative water source during the dry season, which is used majorly for livestock and irrigating crops.
Because the technology is promoted as a supplementary water source for the dry season, during the wet season grass may grow on top of the protected hole. Before its use in the dry season the land user removes the grass before abstracting the well water for livestock or crop production.
The resources required for establishing and maintaining this technology include knowledge of suitable sites for the technology, expert advice on construction of the structure, labour, and tools (e.g. hoes, spades, poles, etc.).
This technology is liked by farmers because it is fairly inexpensive and easy to maintain. It may be considered costly are at the establishment level but in the long run, the returns are worth the investment. The other concern is that it can be contaminated when managed poorly.

2.3 Photos of the Technology

General remarks regarding photos:

The grass left to grow does not imply poor management but a protection for a longer period leading to dry season when there is shortage of water.
