2.1 ຄໍາອະທິບາຍສັ້ນຂອງ ເຕັກໂນໂລຢີ

ການກຳໜົດຄວາມໝາຍ ຂອງເຕັກໂນໂລຢີ:

Excavations in streambeds to provide temporary storage of runoff, increasing water yields from shallow wells for supplementary irrigation.

2.2 ການອະທິບາຍ ລາຍລະອຽດ ຂອງເຕັກໂນໂລຢີ

ການພັນລະນາ:

Dohs are rectangular excavations in seasonal streambeds, which are intended to capture and hold runoff to enhance groundwater recharge, thus increasing water for irrigation from nearby shallow wells. They also collect and impound subsurface flow. Dohs are built in semi-arid areas where rainfall is low and seasonal. The dimension of a typical doh is 1.0-1.5 m deep with variable length (up to 40 m) and width (up to 10 m) depending on streambed section, with an average capacity of 400 m3.

Purpose of the Technology: The excavated material is deposited along the stream banks as a barrier against siltation from surrounding areas. The slopes of the excavation are gentle (an upstream slope of 1:6 or 17% and a downstream slope of 1:8 or 12%) so that water flows into it, and excess water out again, carrying silt rather than depositing it. The sides however are steep, to increase capacity - and would benefit from stone pitching to stabilise them. A silt trap comprising a line of loose boulders is constructed upstream across the streambed. Dohs are generally built in sequence. They may be as close as a few metres apart. Bends in the stream are avoided as these are susceptible to bank erosion.

Establishment / maintenance activities and inputs: The technology is used in conjunction with shallow wells (odees), which enable farmers to harvest the increased groundwater for supplementary irrigation of annual crops- including vegetables such as chilli peppers. Water is pumped out of the wells. In the case study village, Mohanpada, each doh basically supplies an underground source of extra water to one well. Communities together with project staff carry out site selection, and then detailed design/estimates/layout is done with project technical assistance. As a supportive measure the catchment area is treated with gully plugs (small stone checks in gullies). A water harvesting tank (small reservoir or dam) may be excavated above the series of dohs where this is justified by a sufficiently large catchment area/suitable site. The capacity of the tank at Mohanpada is around 600 m3 and thus also has a positive impact on groundwater recharge.

Natural / human environment: Maintenance is agreed through meetings of user groups: manual desilting is planned and repairs of gully plugs also. In summary, dohs are low cost water recharge alternatives for poorer communities, and in this case study, the extra area brought under production has meant that all families that require it, now have access to some water for irrigation.

• ກະສິກໍາແບບປະສົມປະສານ (ລວມທັງ ການລ້ຽງສັດ-ປຸກຝັງ)

ຄວາມຄິດເຫັນ:

Major land use problems (compiler’s opinion): There are regular poor yields of agricultural crops on the degraded, rainfed fields. A further constraint is the limited amount of water in wells, restricting both the extent of irrigation, and the number of people with access to irrigation. There is an underlying problem of poverty, which in turn leads to seasonal out-migration to find work.

Major land use problems (land users’ perception): Agricultural lands: sloping fields, soil loss, poor yields. Common lands:competition from surrounding villages for grazing resulting in low yields. Private pastures (bir): small patches which are not sufficient to meet the fodder needs. Settlement area: 28 huts already erected. Additional space not available.

Other grazingland: extensive grazing: on patches of waste lands within fields

Type of cropping system and major crops comments: During monsoon (kharif) season the main crop is cotton + maize. In addition minor pulses are taken. If water is available for irrigation, this is followed by wheat+gram in winter. Major area is fallow in winter except for the cotton crop which is of longer duration. No cultivation was observed in summer.

ຄວາມຄິດເຫັນ:

The construction of one doh costs between US$ 200-400, depending on the size of the doh (approximately one cubic metre can be excavated per person day at a cost of one US dollar). On a per hectare basis the costs are very variable, since they are related to the extra area brought under irrigation. In this case study there are four dohs within a total village area of 50 ha. Ten of the 50 ha have been brought into irrigated production (extra to the 5 ha already irrigated) due to the four dohs and the ‘tank’ and the costs outlined above are spread over those 10 ha. In this case half of the costs are directly attributable to dohs (average capacity 400 m3 each), and half to catchment treatment where the water-harvesting tank (a reservoir of approximately 600 m3) is the main cost. Where there is underlying rock, mechanical drills and blasting by dynamite may be required, which increases the costs. That was not the case in this village. The cost of deepening/widening the five wells (odees) has not been included here: that is carried out by the villagers themselves. While the project normally pays around 85% of labour costs, here at Mohanpada village the project only needs to pay 75%, due to a high level of commitment by the villagers.

The total of 4 doh structure were constructed along a stream length of 451 m having gradient of 1.2%. Total storage capacity is 1646qm. It is observed that during past year (2002) the structures were completely filled & subsequently emptied (percolated) 5 times.

Dohs are a low cost alternative method of increasing groundwater in a semi-arid area where production of high value legumes depends on irrigation – and dohs represent the best way in this situation of expanding the extent of irrigated land, and bringing irrigation to more families.
Small, multiple recharge points for replenishing groundwater for irrigation from wells How can they be sustained / enhanced? Breaking hard pan in stream bed mechanically by drills or blasting to deepen dohs and thereby make them more effective.
