2.1 Технологийн товч тодорхойлолт

Технологийн тодорхойлолт:

These are constructions stretching across the sand filled dry riverbed, down towards the impermeable floor of the riverbed. They are totally submerged into the ground. For example by fully covering after construction by sand. This are done along dry rivers with huge sand deposits, which has high yield potential and where water can be easily extracted. The aim is to raise groundwater tables and increase the storage capacity for water withdrawals.

2.2 Технологийн дэлгэрэнгүй тодорхойлолт

Тодорхойлолт:

The technology is applied in northern rangeland of Isiolo County which is managed under communal management systems. The aim of technology to reduce pasture and water availability imbalances. The dimensions of sub-surface dam include: a length of water spread (103m),width of the dam (15m), width of water spread (18m), effective dam height (2m), volume of retained sand (103 x 0.5(15 +18) x0.5 x2.0 = 5098.50m3) and the volume of water that can be abstracted from the sand bed (25/100x 5098.50m3 = 1274.6.36m3).
The technology functions as underground water storage infrastructure and the typical activities include, excavation of top porous soil, excavation of sample pits within the excavated area, checking filtration rates of soil, compaction of soil on which dam liners are laid, smoothing the sharp liners along which the dam liners are laid, making grooves to anchor the dam liner, laying the dam liner, anchoring the dam liner with a mixture of cement, water proof and sand with water (motor) and finally drying of the motor and filling back of sand.
The development of Sub-Surface Dams (SSDs) was done through Cash for Work program where local labours comprising of 40-50 persons are engaged in excavation, compactions and developing the liners. Farm tools like jembe, panga, spades and human labour are required to develop the SSD. The technology improves water supply/availability, thereby extending the period of livestock grazing in areas where typically water is depleted before the pasture hence improves water access for livestock in ways that support wider management and utilization of the rangeland and as such strength the resilience of pastoralists to droughts. This effectively gives pastoral groups, an extra grazing time (typically 2 extra months), a period usually not too long to encourage land degradation through over-grazing but long enough to enable pastoralist utilize the remaining pasture in wet season grazing areas. In so doing, the technology enable balanced use of vast communal lands without livestock retreating to dry season grazing areas.
In the process of the landscape level participatory planning with the communities: i) they identified different challenges, including need for decommissioning certain water points that they consider are contributing to over grazing and also attracting other communities, hence drive frequent conflicts, secondly, ii) they mapped areas in the rangeland where there is mismatch between water and pasture availability, most of these areas are in wet season grazing areas. So the next discussion was on what strategic water infrastructures that will enable herders to graze for 2 -3 extra months to enable them utilize the grass before they migrate to the traditional dry season grazing areas. So by design, the technology should only yield water that can allow settling for those extra months, not longer to the detriment of the rangeland
The technology was instrumental in fostering both balanced utilization of land and strengthening sustainable use of the vast rangeland by ensuring that herders utilize available pastures in the wet seasons grazing areas before moving to dry seasons grazing areas. The water stored through the technology stays longer, in this case study, the water lasted for 5 months after the end of the rainy season .
The area receives bimodal rainfall, long rain in March-May and short rain in November-December. With changing seasons/climate, the dry seasons can last up to 1 year in case of rainfall failure. Typically, dry seasons are 6-7 months (May- November).
Normally, the water is depleted within 2 months after the rainy period. The technology is also cheap and easy to understand and construct (especially in areas with clay as the underlying impermeable material) with a possibility of the communities to be taught how to identify suitable site and the entire process of construction. However, in areas without clay soil, the excavation of clay and transportation can be labour intensive and expensive.

4.1 Технологийн техник зураг

4.2 Техникийн үзүүлэлт/ техникийн зургийн тайлбар

The SSD has initial excavation works. The construction of the SSD was constructed by 50 laborers. The area of excavation is subdivided into 45 square chambers of 4X2.3X2.2= 20.2M3 (not to scale). Each of the chambers were excavated by 5 laborers. The estimated time for excavation as per the plan was estimated to be five days. Excavation and transportation of the clay from the clay pit was estimated to take an approximate of five days while the compacting of the clay will follow one week later, and laying out of the concrete and refilling of the sand for another week. The liner will then be finally placed. In summary, the excavation of sand takes 5 days, and the excavation of clay soil takes another 5 days while concrete placing, compacting of clay as well as putting of liner and refilling of sand takes 10 days.

6.7 Технологийн давуу тал/боломжууд

Газар ашиглагчдын тодорхойлсон давуу тал/боломжууд
The technology created opportunity to graze in wet season grazing areas for an averge extra 2 months period after rainy seasons. The technology has provided additional water that gave herders extra days to graze in wet season areas and utilize the pasture that would have been unutilized due to water constrains. In so doing, the land users utilized the pasture without retreating to traditional dry season grazing areas.
The extra grazing months has reduced overall livestock mortality during droughts and also improved resilience of pastoral community.
The distance travelled and effort required to access water was reduced. Community members reported reduced distances covered and time spent in search of water for livestock. In some instances the distance reduced from 12-15 Km to 3 Km. Community members also mentioned reduction in conflict incidences over water resources in some areas due to adequate supply of water as a result of construction of water infrastructure.
The balanced utilization of the grazing area through SSD water provision, enables herd to graze in wet season grazing for slightly longer period and utilize pasture optimally, this however, does not mean that during that garzing period, there will be overgrazing. The volume of water available restricts the number of animals sustained by the grazing area.

Эмхэтгэгч, бусад мэдээлэл өгсөн хүмүүсийн өнцгөөс тодорхойлсон давуу тал/боломжууд
The technology has created an opportunity to optimally use the grazing area and overall reduced land degradation. The technology Improves access to water for livestock in ways which promote more sustainable management of rangeland resources and as such strengthening the resilience of local communities.
The validation process prior to construction of the SSD is draws critical lessons of identifying and agreeing on where to construct the SSD in a way that fit within broader sustainable rangeland management in a manner that ensured sustainable and efficient utilization of pasture and browse resources in targeted areas. The increase in water supply allowed livestock to graze additional 2-3 months in target areas before shifting to dry grazing areas where previously they migrated before exhausting the pasture and browse resources due to water scarcity. The dry season grazing area is towards Merti, in Kom and Sabarwawa where there are deep boreholes, under, lock and key and only opened during dry seasons. In typical year, the dry season period is about 7 months. But when one rain season fail it goes to about 11 months.

When the construction season for SSD is not well planned, there is likelihood/risks of the dams being washed away by flash floods.	Better planning and timing of the development of SDD, just slightly before the onset of rainfall.
