Annex C
Progress in Implementation of Construction Activities
A.I. Construction and rehabilitation of the South Karakalpakstan Main Drainage Canal
-
The subcomponent works contract (SKMD/13) started in September 2005 and with an extension of 95 days and delays of a year in the works program was completed in December 20104. Works completed under the contract included the rehabilitation of the Karakalpakstan Main Drain (SKMD), construction of the Akchadarya Main Drain (AMD) and construction of 125 structures associated with the drains including bridges (11), aqueducts (7), conjugation structures (31) and cross regulators (9). Annex E lists a summary of dates, quantities and cost for all works contracts.
-
Subsequent to the completion of the SKMD/1 contract, additional new and remedial works were identified on the AMD to increase capacity in the drain reach upstream of the original works. The contract commenced in January 2011 and is currently on-going with approximately 21% of the earthworks completed as of February 2011.
A.2. Rehabilitation of inter-farm collector drains and irrigation infrastructure.
-
The works contract (MS/1) started in September 2006 and with contract duration of 36 months and later extension of 263 days the scheduled completion date was 12 June 2010. The contractor failed to achieve the scheduled completion date and completion is still pending. The reasons for the delay included shortage of fuel supplies and adverse winter weather conditions5.
-
The works main elements include inter-farm collector drains (250 km), irrigation structures (25 nos.), land leveling (4,250 ha) and deep ripping (1,500 ha). While the works are substantially complete, the remaining works6 include approximately 175,000 m3 in earthworks, 135 m3 in concrete works, and small areas of deep ripping and land leveling7. The outstanding earthworks and concrete works are approximately 7% and 3% of the contract quantities. In addition to outstanding works the contractor is to submit certified as-built drawings and Operation and Maintenance (O&M) manuals for the collector drains and irrigation structures.
-
The Contractor’s revised work program indicated that works and submissions will be completed by the 30th April 2011.Work is currently on-going and it appears that all works and submissions will be completed within the revised program timeframe8.
B.3. Rehabilitation of major structures and canals
-
The subcomponent includes two works contracts (CAR/1 and D1/2) for rehabilitation of irrigation and drainage infrastructure within Turtkul and Beruni districts. The D1/2 contract is additional works, funded from cost savings on earlier contracts.
-
The CAR/1 contract start date was 13 June 2007 and with contract duration of 24 months to which there have been two time extensions of 365 days (Additional Agreement No. 1) and 397 days (Additional Agreement No. 2). The scheduled completion date is 14 July 2011.
-
The works under CAR/1 Additional Agreement No. 1 were completed in December 20109, however there remain several outstanding issues including rectification of non-compliances and under-excavation works on structures and collectors, and correction of as-built drawings.
-
In September 2010 the contractor commenced work on CAR/1 Additional Agreement No. 2. Scheduled works include rehabilitation of 429 km of farm collectors, and construction of drainage (40 new and 51 rehabilitated) and irrigation (5 new and 21 rehabilitated) structures. As of February 2011, completion of physical works was approximately 22% and 8% of farm collectors and structures respectively10. For collectors actual works were slightly lower than planned and for concrete actual works was 50% of planned. To achieve the scheduled completion date the contractor needs to increase resources, equipment and manpower and submit a revised work program.
-
The D1/2 contract start date was 6 January 2011. With a duration of 17 months, the completion date is 6 June 2012. The works include rehabilitation of 540 km on farm collectors, repair and construction of drainage structures (70 pipe culverts, 52 pipes under canals and 51 junction structures), repair and construction of irrigation canal structures (3 cross regulators, 4 box culverts, 24 outlets and 3 pipe culverts) and construction of 279 new observation wells.
-
As of March 2011 works had started on farm collectors with approximately 1% of the earthworks completed and with construction works yet to start on structures and observation wells. The works also included remedial earthworks for the AMD (as discussed in Section A1)11.
Annex D
Sub-component B.2: Irrigation and Drainage Improvement
Demonstration Plots
-
During 2005-2009, a total 15 demonstration plots (DP) were established in Beruni and Turtkul districts. To date a total of 100 farmers have received hands-on training on the DPs, and visits for about 100 farmers to the DPs were organized. The following activities were demonstrated: (i) laser land leveling, (ii) deep ripping to a depth 60 cm, (iii) water measurement, (iv) installation of piezometers for monitoring ground water mineralization and level, (v) application of organic fertilizer, (vi) irrigation application at exact norms on the basis of crop water requirements, and (vii) timely execution of surveys for weeds, pests and control measures by biological methods. As a result of this, wheat, cotton and vegetable yields on DPs increased by 30%, and the plots were thus successful in demonstrating that substantial increases in yields can be obtained in lower potential soil.
Farmers Information Support Desk (FISD)
-
A combination of theoretical (in class) and practical training was provided through Farmers Field Schools (FFS). The training was carried out at least twice a year, once at the beginning of June after the winter wheat harvest and later in autumn after completion of the cotton harvest. FISDs provided advice and assistance to 338 farmers. This activity is ongoing and will continue until project completion. Training modules under this task include study of soil property, agricultural mechanization, crop production, plant protection, water and soil monitoring, operation of on-farm irrigation and drainage infrastructure, and social and legal aspects of farming.
Development of Training Material
-
Training booklets and bulletins were prepared on 39 different subjects. More than 14,000 booklets and 860 bulletins have been distributed through FFS and via local Mayor Offices to farmers of Beruni, Turtkul and Ellikkala districts. More than 100 posters have been distributed for training purposes.
Annex E
Project compliance with safeguards policies
Environmental Assessment (OP4.01)
-
The mission noted that contractors have not been adequately trained in the implementation of the Environmental Management Plan (EMP). For contract D1/2, it was agreed that the PIU will, by June 30, 2011, train the contractor in EMP to ensure compliance. A key target indicator is to minimize complaints from inhabitants in the project area.
Natural Habitats (OP4.04)
-
Regarding livestock, thirteen new livestock routes are constructed to compensate for the routes that were demolished as they interfered with DIWIP layouts. Livestock can be subject to vector-borne diseases due to irrigation expansion and newly inundated wetlands, as well as desertification caused by drying some of the existing wetlands.
-
Regarding Lake Ayazkala, the western lake is fully salted and the eastern lake is partially salted due to reduced drainage flows. The PIU informed the Bank of the government’s intention to close the lake (as required per the EMP/ISDS). It is not economically feasible to flush the salts in the eastern lake as envisaged by the EMP and ISDS. Within the coming 1-2 years, when salt is mixed with the blown sand, soil below the salt layer will lose its moisture, and the top soil will harden; only then should measures for stabilizing the salts start. The aim is to prevent the salt from being blown away by wind to avoid negative impact on human health in adjacent towns.
-
To compensate for the loss of Lake Ayazkala and the other small wetlands that dried up, constructing the SKMD and AMD enabled creating new small adjacent wetlands (Ozarni wetland and two others), and also increased the drainage outflow to Lake Akchakul (used for boat recreation and fisheries). The M&E task will assess the net effect on fisheries, flora and fauna. Water supply to Baday Tugai forest was intended from Budeniey canal (instead of the drainage pumping station that closed due to DIWIP). However, while digging Budeniey canal farmers requested adding irrigation offtakes for their farms; hence water was inadequate for the forest. Thus the project built Kok-Darya canal, with another canal extension and flow regulators, to supplement water supply to the forest. As the Kok-Darya canal is dependent on the flow in the lower Amu Darya (which is often low), it is recommended under SKWRMIP to provide an adequate amount of water to the Bustan-canal for supplying water to the forest, without any competition from irrigators.
Physical Cultural Property (OP4.11)
-
The groundwater table in areas adjacent to SKMD and close to adjacent monuments has improved, but in some irrigated areas, despite introducing the SKMD and AMD, water tables continue to be relatively high because farmers continue to over-irrigate. This issue, under the SKWRMIP, warrants: (i) creating more WUAs and empowering them through training and phase-out technical backstopping by MoAWR staff, (ii) irrigation advisory services, and (iii) remodeling many inter-farm canals.
-
The SKMD bank spoils had negatively blocked the visibility of the Kyzyl-Kala monument, but now these spoils have been removed. In SKWRMIP there needs to be a minimum distance of 150 meters between the introduced I&D works and key monuments.
Dam Safety (OP4.37)
-
For Tuyamuyun reservoir and dam system, the EMP had recommended undertaking: (i) an Emergency Preparedness Plan (EPP); (ii) upgrade of hydro-mechanical equipment and dam-operation instrumentations; (iii) implementation of civil works for safety of Sultansanldjar Dam; and (iv) update of the reservoir-scheme O&M manual. Of these, DIWIP was expected to implement, if needed, only the most priority activities at around US$1m; whereas an estimated $11 million of the other proposed activities would be funded by GOU parallel financing and by the “Water Supply Sanitation and Health Project (Ln 4216-UZ)”. Thus far DIWIP has conducted a flood management study in relation to the EPP. The mission has not been able to ascertain the nature and scope of works that have been undertaken by the Government. The mission would like to receive clarification on follow-up activities that have been taken in response to relevant clauses of the Environmental Assessment (EA) and the Environmental Management Plan (EMP). To that effect, the Bank will send an official request to MoAWR.
-
Implementation of some of these proposed activities has been constrained by the fact that Turkmenistan shares the reservoir/dam with Uzbekistan. During the preparation of SKWRMIP, clear actions that recognize the transboundary nature of the dam will need to be identified to ensure compliance with OP4.37.
