ANNEX 1.1 - DESCRIPTION OF 09 SUB-PROJECTS
Three (03) Sub-Projects are implemented in the first year (SP6, SP9 and SP4).
-
SP4- Improve and upgrad small scale irrigation schemes in Luong Son, Lac Son, Tan Lac, Cao Phong and Mai Chau districts, to irrigate 1,048ha of rice and vegetables. The main objective of the SP4 is upgrading and improving of 10 weirs, 09 turbine pump stations and 01 electric pump stations which damaged by many years of operation, to supply water and electricity combined rice milling . The number of people beneficiaries after SP4 completion is 21,448 people, in which 9,281 ethnic minority people (43%).
-
SP6- Improve and upgrade the South Ma irrigation scheme: There are 11,154ha cultivated area and 450ha of aquaculture are irrigated by Nam Song Ma irrigation system, supplied from Ma river through by Nam Song Ma pumping station. Currently the system ensures only 6836ha irrigated area (reaching 61% of demand), the left area pumped from about 39% of river Chu, Ma, Cau Chay or pump up drainage canals. However, due to the impact of climate change in recent years, so the water level in dry season of the river is lower than the annual average of (0.3÷0.9) m, the pumps couldnot operate according to the designed capacity and leading to droughts occur frequently, saltwater intrusion into the interior, and water shortages affect crop yields. The sub-project area is in Yen Dinh and Thieu Hoa district. Total population is 871,401people beong to 215,605 households. Over 80% households has income from agricultural production. 100% of households is Vietnamese, no minority in the subproject area. Poverty rate is 16.4%. The main objective of the sub-project is repairing and upgrading the canal system to get water from Cua Dat reservoir to irrigate 11.154ha and then close totally Nam Ma River pumping station12. The number of beneficiaries after SP6 completion is 195,000 people.
-
SP9- Improve Phu Ninh irrigation scheme. The subproject area is located in the Quang Nam Province, where annual prone to natural disasters such as floods, droughts, landslides, salinity at estuarine of Phu Ninh and Khe Tan irrigation area, with command area belong to districts of Nui Thanh, Phu Ninh, Thang Binh, Que Son, Duy Xuyen and Dai Loc. Population is 385.165 people, and 100% is Vietnamese, no minority in the subproject area. It is accounted for 80% farmers in the subproject area. The poverty rate is from 10.1 to 17.3%. Phu Ninh irrigation system is irrigated for 19.427ha and supply for about 200,000 people with discharge is 0.23 m3/s. Khe Tan Irrigation system is responsible for irrigation of 3,500ha, but at present time, it can provide water for 2,100ha (obtain 60% as required); the remain area is bare land because no water for cultivation. The Phu Ninh Irrigation system was repaired, upgrated headworks and some sections of main canals, branches, hydraulic strcutures and installed the SCADA system by VWRAP (WB3). The major objective of SP9 is rehabilitation, upgrading several broken canal sections, and construction of new irrigation canal (namely N30) with 4.5km long, in order to take water from Bac main canal cross to Ba Ren River to irrigate for 1,800ha cultivation, where always surffering with saline problem, and closing 05 irrigation pumping stations used to provide water for this area, because saline water source13. Total beneficiaries after SP9 completion is 406,760 people.
The remaining Sub-Projects will be implemented in the Phase 2:
-
Ha Giang irrigation system (SP1 and SP2). Ha Giang is located in the north far of Vietnam, is complicated terrain 70% hilly, can be divided into three regions: northern rocky mountain region, steep slope, river is divided. High hilly area at western part is upstream of Chay river, steep slopes, high passes, narrow valleys and stream .Lower ares is included valley of Lo River and Ha Giang City.

SP1 will upgrade, improve and repair 09 small earth dams (maximum height is 14m), upgrade, repair the 23spillway, and upgrade, repair and reinforcement of the canal system and water pipe system.
SP2 – improve and upgrade irrigation systems and construct multipurpose village ponds in Dong Van, Quang Ba, Yen Minh, and Meo Vac districts. There are many ethnic groups living together as H'mong, Tay, Han, Chinese, Dao, Nung, Co Lao, San Chay, Bo Y, more than 90%. Main income is from farming cattle, goats, pigs and poultry. 19%/year rice and 79% corn production, there are also other crops such as peanuts, soybeans, vegetables. People have to get water from the stream or the lower regions, with 5-7km far. Therefore it is not enough water for drinking and livestock. Crop yields as rice, corn and legumes are uncertain due to lack of irrigation water. When completed SP2, 16,954 beneficiaries, of which 3,687 ethnic minority people (22%) have water for domestic, livestock and irrigation of crops. Building scale is 16 multi-purpose reservoirs, with a capacity of 3,000-5,000m3 of water and 01 water reservoir with a capacity of 56.100m3, and concrete, rectangular cross-section canals.
-
SP3 – Improve Drainage and Irrigation Systems in Tam Nong and Thanh Thuy Districts. Phu Tho is a hilly area track bond with delta, hence hilly is predominated in Phu Tho. The topography of the province is divided by large rivers such as the Thao, Lo, Da and Chay River, mountains, ... 79% moutainous area, 14.35% midlands and plain which account for 6.65% natural provincial land; agricultural land per capita is low and disperse, 526m2/person14. The main objective of SP3 is drainage for 16,765hectares cultivated land of annual flooding, 788ha cultivated land due to water shortages in 14 communes in two districts Tam Nong and Thanh Thuy. Drainage catchment of Dau Duong pumping station has 78.6% agricultural land, one third of agricultural land is forest, whole of planted forest and no primary forest. Drainage catchment of Doan Ha pumping station has 65.7% of agricultural land, and forest accounts for about one fifth of agricultural land. The main income is from agriculture. Average poverty rate in the sub-project is 20%. 100% Vietnamese people is in the subproject, no ethnic minorities. SP3 is included building 02 drainage pump station to release to Da and Hong river, improving and upgrading 05 pumping stations and permanent 3,468km on-farm canal and building 02 bridges. The total beneficiaries will be 76,705 people after SP3 completion.
-
SP5- Improve small scale irrigation system in Hoa Binh province Hoa Binh is a mountainous province, combination between mountains, valleys and plains, therefore irrigation system is often in small scale and dispersed, such as reservoirs, dams, turbine pump, electric pump and small canal system. SP5- upgrading and improving the irrigation system in Hoa Binh province for 14 communes in 6 districts as Lac Thuy, Kim Boi, Luong Son, Lac Son, Tan Lac and Yen Thuy in Hoa Binh province, to supply 3.328ha of rice and vegetables, and 472.2 hectares of aquaculture. A total of 16 groups of hydraulic strutures, including 25 reservoirs and 03 weirs. The total number of beneficiaries of SP5 is 21,340people, of which 5,687 ethnic minority people (26.6%), they are majority Muong people.

SP7 – Improve Ke Go and Rac river Irrigation Systems, . Ke Go and Song Rac irrigation systems is supplied water for 26.838ha of cultivated land, 1.287ha of aquaculture, 253,298 people of 04 districts Ky Anh, Cam Xuyen, Thach Ha, Ha Tinh city (total 21 communes), with a total population of 314,053 people of 84,379 households, accounting for 58% of the total provincial population. Ke Go irrigation system supplies 20.003ha cultivated land, 1087ha aquaculture and 1.65m3/s domestic water. Ke Go irrigation system was upgraded hydraulic head, modernized main canal system, first, second and third level canal and model irrigated area N3,5 and N4,6. It has showed obvious effectively, as irrigation area increase from 12,400ha (2006) to 14,000ha (2011); Water savings for irrigation is about 40 million m3/ year (before, total water consumption of both the spring and the summer-autumn crop was about 260 million m3/year and after upgrading, water consumption is only around 220 million m3/year). However, a portion of cultivated area (7,563ha) is still adequated water cause of the canal system and hydraulic work is damaged. Rac River Irrigation System supplies water for 8.150ha cultivated land, but now only meet 52% (4.200ha) of demand. At the end of the canal, water is irrigated 25 days delay, does not meet the water demand of the crop period, therefore it leads to decrease productivity and sometime entire lost. The main objective of SP7 is improving and upgrading on-canal structure and canal to ssupply enough water for user, and ensure water level and discharge in the canal to support effectively water management.
