2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

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 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

The technology is applied in northern rangeland of Isiolo County which is managed under communal management systems. The technology involves soil excavation which are typically subdivided into a number of square chambers measuring 4X2.3X2.2= 20.2M3 (not to scale). Then, excavation and transportation of clay soil from the clay pit and final compaction of clay soil after approximately a week, and lying out of the concrete and refilling of the sand. Finally, a liner is placed. The technology functions as underground water storage infrastructure. 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. 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 technology aim to improve 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. Inputs such as farm tools like jembe, panga, spades and human labour are required to develop SSD. The technology improves water supply/availability, thereby extending the period of livestock grazing in areas where typically water is depleted before the pasture. This effectively gives pastoral groups, an extra grazing time (typically 2 extra months) that is not too long to lead to 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. The extended grazing period is instrumental in building resilience of pastoral communities in the face of climate variability. The technology was instrumental in fostering both balanced utilization of land and strengthening sustainable use of the vast rangeland by moderating the mobility between wet season and dry season 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. 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.

4.2 ການແຕ້ມແຜນວາດອະທິບາຍເຕັກນິກ

The SSD has initial excavation works. The construction of the SSD was constructed by 50 laborers. The design attached represent an Aerial view of the area of excavation that 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 5days, and the excavation of clay soil takes another 5days while concrete placing, compacting of clay as well as putting of liner and refilling of sand takes 10 days.

The technology created opportunity to graze in wet season grazing areas for extra 2 months period after rainy seasons. The technology has provided additional water that extended, albeit slightly, the grazing period of the land-users. 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 traveled 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 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.
