No

2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

The technology promotes the lifting of river water by pump sets and conveys the water through buried pipelines to a canal. The conserved canal water is used for irrigation delivered by low lift pumps (LLP). Because water is held in the canal it revitalises the ecosystem along its length. Furthermore, using river water for irrigation avoids dangers associated with groundwater depletion.

2.2 Detailed description of the Technology

Description:

The project is sited at Sharmongla under Godagari Upazilla of Rajshahi district. The Sharmongla canal is located about 3.5 km away from the Padma river. Its total length is 29.0 km. Under this technology, water is lifted from the Padma river by pumps set on a pontoon. The lifted water is then discharged to a canal through underground pipelines. The water so discharged is lifted to the crop fields (delivery points) for irrigation. The elevation difference between the delivery points and the sourcing river is about 21 m. There are numbers of submerged weirs/dams constructed across the canal at different locations for conserving water: the water then helps regenerate the ecosystem along its banks and enriches the habitat.
Pontoon at a glance:
•Year of construction: 2004
•No. of centrifugal pumps at pontoon: 12
•Pump capacity: 50 m lifting height.
•Power of each pump: 60 HP
•Capacity of each pump: 2.5 cusec
•Total capacity of pump sets: 30 cusec
•Capacity of electric sub-station: 750 KW
•No. of discharge pipelines: 12

Sharmongla canal at a glance:
•Length of the canal: 29 km
•Average width of the canal: 15 m
•Average depth from ground level: 5 m
•No. of submerged weirs and dams within the canal: 14
•No. of LLP (low lift pump): 27 electrified and 6 solar pumps
•Total irrigated area: 1850 ha
•Benefiting farmers: 5330
•Harvest yield of rice per year: 20,500 metric tonnes (approx.)
•Afforestation on the canal bank: 65,500 trees

Purposes/objectives of the technology:
•The main purpose of the said technology is to provide water for irrigation. This prevents abstracting of groundwater, which has adverse effects on the environment: therefore this system is environment friendly.
• Enhancing groundwater recharge thereby supports ecosystem function.
•The storing of river water in irrigation canals supports the enrichment of the habitat.

Approach for implementing the technology:
There was no irrigation facility for crop production in this drought-prone area. Government officials came to the locality, discussed with the local community, elites, as well as the farmers. Finally, the local community was convinced about the technology. Then the irrigation system could be implemented in the area. On seeing the success of the technology, the same has been replicated on approx. 9400 ha. in Barind area, benefitting approx. 32,200 farmers.

Maintenance of the technology:
In case of problems, the respective mechanic of that area informs the Assistant Engineer through the Sub-Assistant Engineer. Thus the problem is solved by their own initiative. It is also monitored by the Executive Engineer of the respective District, and finally by the Executive Director from the headquarters if needed.

Crop cultivation:
Due to the application of the technology, previously fallow land has come under cultivation/irrigation facilities, mono-cropped land has been converted into multi-cropped land. Different crops, like rice, wheat, maize, mustard, pulses, potato, tomato, spices and other vegetables are cultivated.

Farmers’ acceptance:
The technology has been well accepted by the farmers, as uncultivated land has been brought under cultivation and different crops are now being cultivated year-round.

management measures

management measures

  • M2: Change of management/ intensity level

Comments:

There are two stages of harvesting water.
1 - from river water, which is not going directly to the field
2- water reserved in canals and supplied to the field
Para S10 - refers to saving conventional electricity by using solar power for distribution of water to fields

3.7 Main types of land degradation addressed by the Technology

water degradation

water degradation

  • Ha: aridification
  • Hq: decline of groundwater quality
Comments:

Barind was driest part of Bangladesh. It was enhanced when groundwater abstraction increased to support cropping by irrigation. The reduction of the groundwater table enhanced the dry out of dug wells, which supported domestic consumption. Hence, aridification was prominent in the area. It is reported that after the application of this technology, there are indications of recharging of the groundwater. Due to the increase in vegetation, the local temperature tends to be cooler than before.

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:
  • prevent land degradation
  • reduce land degradation
Comments:

This technology helps reducing land degradation through using river water rather than groundwater for irrigation, thereby
preventing land degradation through increasing the vegetation cover on land.

Comments/ specify:

Basically in this area could be grouped in to two. One group has almost no land and previously they have to migrate beyond barind area as labor and they were poor. At present they have job (agri-labor or otherwise) in their area and become more solvent then past 90's. On other hand the second group cultivate the land of their own or leased, which they could not in 90's. They also in handicap because of poor crop and no option to cultivate in two seasons. Hence apparently both groups as of their status are in well shape. The peoples those who have no land for cultivation now can engage them in many other entrepreneurship (e.g. farm product marketing, livestock/poultry raring, carpentering, grocery, etc etc) emerged.

This comment was done comparing between conveying water by open drainage and through pipeline. Definitely there are almost no run-off from pipe line distribution. On the hand land users have to confirm their field bunds to protect run-off. Prepaid metering system also restricted land users not to allow excess water to over flow from their field. In-spite of that there may be small amount run-off, but the detachment of top soils is within tolerable limit and accumulate within field bunds.

6.5 Adoption of the Technology

  • > 50%
If available, quantify (no. of households and/ or area covered):

It could rather to explain as the beneficiaries of the technology. Truly a single land user or a group of land user will not able to install this type of system for multiple reasons. There are two components of this technology, one is the government institution who provided the scope of using surface water for irrigation and the second one are the land user who use the scope or facilities of irrigation system Here about 1800 farmers are involved to use surface water as their irrigation source.

Of all those who have adopted the Technology, how many did so spontaneously, i.e. without receiving any material incentives/ payments?
  • 91-100%
Comments:

Most of the farmers of the area who has land adopted surface water for irrigation instead of ground water abstraction.

6.6 Adaptation

Has the Technology been modified recently to adapt to changing conditions?

Yes

If yes, indicate to which changing conditions it was adapted:
  • labour availability (e.g. due to migration)
Specify adaptation of the Technology (design, material/ species, etc.):

where there are no canal for water storage , local ponds are used to reserve the surface water to irrigate land surrounding the pods and obviously where river water could not be reached.
