2. SLM技术的说明
2.1 技术简介
技术定义:
Water from the Hunza river was lifted through solar powered pump, stored above ground plastic tanks and applied to newly planted apple orchards through efficient drip irrigation. Mulch was applied to the plants to conserve soil moisture.
2.2 技术的详细说明
说明:
The fragile rouged mountains prone to the effect of climate change makes the mountain com-munities in Gilgit-Baltistan of Pakistan more vulnerable. Agriculture is the major source of their livelihoods and it purely dependents on glacier meltwater which makes the community more susceptible due to the unstable behaviour of the glaciers. Irrigation is practised with traditional irrigation canals, intake of which is located at glacier terminus. On one hand lowering of glacier surface disconnects many irrigation canals. Uncertain glacier behaviour has resulted in the decline of water availability and even forced some communities to abandon their agricultural land. On the other hand, only 2% of land in Gilgit-Baltistan is used for agriculture purposes whereas a huge chunk of barren land lays above the Hunza River, which cannot be cultivated through the traditional irrigation system hence it remains unutilized.
To address both issues, ICIMOD together with a local level partner’s consortia piloted solar water lifting to irrigate barren land for establishing apple orchards along Hunza River at Passu and Morkhun Villages. These two villages are located far from each other. In each village, orchards of 2.5 hectare area were established and the drip irrigation system installed was efficiently used to irrigate apple plants. Similar technological packages (solar pump, drip irrigation and mulch) were applied in both the villages.
The pumping system comprises a submersible pump (Lorentz, Germany 1 HP) powered by 500 watts solar panels to carry the water to storage tanks (500 litres) made up of plastic that has been placed upslope at 100 feet vertical height from the river. The water from the storage tanks was routed/led to the apple saplings through the surface and pressure compensating drip irrigation system. The pumping capacity of the pump is 7.5 litres/minute, which is irrigating around 3300 apple plants at Passu and Morkhun. The storage tank was kept 60 feet vertical height from the orchard field to be irrigated. Tree to tree distance and row to row distance of apple was maintained at 15 feet in Passu and 10 feet in Morkhun. Drip irrigation (surface and pressure compensating) system was established to irrigate each apple plant, the emitter of the drip system was adjusted according to the plant to plant distance of apple seedlings to be irrigated. Pits were constructed for planting apples and later they also served as water harvesting pits /check basins. Plastic mulch was applied to each apple plants covering a radius around the trunk to minimize soil moisture losses, reduce weed and reduce soil erosion by water and wind.
The cost of an integrated package including solar pumps with accessories, storage tanks, intake and distribution systems (i.e. from river to tank and tank to trees), drip irrigation, apple plants and operational expenses (manpower) for both the sites was US$ 42000 for 5 ha of land. Village Development Organizations (VDO) of both villages take care of maintenance of technological package through a maintenance fund, which is being raised by participating households (HHs). Benefit sharing mechanism has been agreed among the participating HHs. The total income would be divided equally among participating 72 HHs in Morkhun and 135 HHs in Passu.
The technological package was applied in arid climate at an elevation ranging from 2340m to 4877 m above sea level. Passu is located at 36.49o latitude and 74.90o longitude and Morkhun is located at 36.6o N latitudes and 74.86o E longitudes. The area receives 150-200 mm annual rain-fall. The temperature ranges from 11 degree Celsius to 29 degree Celsius. The population of Passu and Morkhun is 1168 and 653 persons respectively. Both villages are semi nomadic and depend mainly on livestock rearing.

最近是否对该技术进行了修改以适应不断变化的条件?:
是
若是,说明它适应了哪些变化的条件:
- 气候变化/极端气候
具体说明技术的适应性(设计、材料/品种等):
Due to heavy load of suspended sediment flowing in the Hunza River, impellers of the solar pump couldn’t function properly. Site-specific customiza-tion of the pump was carried out to make the system functional and to sustain it in the long run.
For that, an outer filter was developed for the pump to avoid sediment entry into the pump. The outer filter is UPVC pipe (of 10-inch diameter and 13 ft long) wrapped with a finely-meshed green net. The out filter was tightly bound together with the pump. The filter with the pump was placed in the river, transverse to the direction of flow. The farmers are also trained to open the clogged drip to release the sediments from time to time.
Damaged solar panel sometimes was replaced. A portion of mulch was buried under the soil. Apple plants were tied together with support stakes. Application of mulch helped to protect apple plants from low winter temperature.
6.7 该技术的优点/长处/机会
土地使用者眼中的长处/优势/机会 |
---|
The solar powered water lifting and drip irrigation is the first of its kind in the upper Indus basin. The system is simple and anyone once trained can operate it. It will contribute to nearly 50% of the additional income of the Passu community. |
The technological package is environmentally friendly and are effective adaptation measures in the context of climate change. |
Women are often most involved in agricultural activities and this intervention has provided them relief by making it possible for them to work nearer to their valley. More over, once the trees bear fruit, women will be able to sell them to generate income. |
编制者或其他关键资源人员认为的长处/优势/机会 |
---|
The first innovative technological package in GB that is climate-resilient as compare to meltwater-dependent flood irrigation is operated by renewable solar energy. |
Water application through drip irrigation is very efficient as compared to flood irrigation, per plant water applied trough drip is 2 litres/day as compared to 30 litres/day through flood irrigation. Integration of mulch enhances soil moisture. |
The technological package can last more than 20 years. Maintenance cost is nominal, it is US$ 100 at the initial stage and later stage it is US$ 300. |
As women are predominantly responsible for farming activities, im-proved water access and application through drip reduces their work-load and frees up time for other activities |
6.8 技术的弱点/缺点/风险及其克服方法
土地使用者认为的弱点/缺点/风险 | 如何克服它们? |
---|---|
Frequent maintenance operation and maintenance of the solar pump due to high sediment concentration of the river from where water is pumped. | Include capacity building activities as an integral part of the technology implementation process. |
Drip irrigation and parts of solar panel may not available locally | A spare parts should be made available locally for immediate replacement as and when required. |
编制者或其他关键资源人员认为的弱点/缺点/风险 | 如何克服它们? |
---|---|
The investment cost is high . | Explain cost-benefit analysis to aware farmers that the benefit is high in the long run. |
Techniques of multiple cropping were not practised to get short term benefits from the orchard field. | Engage the agricultural department to demonstrate and train farmers on multiple cropping in the dry land. |
