After localities basically finished the winter-spring crop, the provincial agricultural sector has implemented a tight production plan for the 2024 summer-autumn crop, with a planting schedule from now until mid-June. Currently, Binh Thuan is facing a shortage of water resources due to drought, so localities need to grasp the weather and water resources to have a production arrangement plan.
Balancing irrigation water sources
According to the water supply plan for summer-autumn crop production of the Provincial Irrigation Works Exploitation Company, the company prioritizes supplying domestic water until July 30, 2024, irrigating the remaining area of the 2023-2024 winter-spring crop, irrigating dragon fruit and fruit trees until June 30 (except Ham Thuan Nam, which is irrigated until May 30; Ham Tan - La Gi, which is irrigated until May 30), the remaining water is arranged for summer-autumn crop production. After a specific meeting, the agricultural sector arranged summer-autumn crop production to ensure irrigation water for nearly 15,000/30,100 hectares of rice and other crops, reaching 49% of the plan. The remaining planned area will be arranged for production in conditions of earlier rains.
Mr. Nguyen Huu Phuoc - Deputy Director of the Department of Agriculture and Rural Development said that, given the current situation of water resources and forecast of unfavorable hydrometeorological trends due to drought, the provincial agricultural sector has agreed on a plan to supply water from irrigation and hydroelectric sources for the summer-autumn crop in 2024. Specifically, in Bac Binh district, the planting area is over 12,400 hectares, including rice, vegetables, dragon fruit, fruit trees; Ham Thuan Bac nearly 13,700 hectares; Tanh Linh and Duc Linh with a total area of over 11,000 hectares, including rice, vegetables and aquaculture. In Tuy Phong district, water supply is arranged for production corresponding to 80% of the planned area, of which rice is nearly 1,700 hectares, vegetables are 225 hectares... In Ham Thuan Nam, Ham Tan districts, La Gi town and Phan Thiet city, priority is given to water sources for daily life and irrigation of perennial crops with high economic value. In May and early June 2024, if the weather is rainy, we will continue to calculate and balance water resources to arrange production but comply with the general seasonal framework.
Concentrated seeding
The leaders of the Department of Agriculture and Rural Development requested that, in order to limit damage to production and lack of domestic water, the Provincial Irrigation Works Exploitation Company Limited closely coordinates with localities to calculate and balance water. At the same time, optimize operation, effectively exploit irrigation systems, synchronously apply the method of alternating water supply in all irrigation systems to coordinate water resources, best meet the water needs of water users according to the existing water resources, and prevent loss and waste.
In addition, effectively use water resources to run generators and supply water downstream from two hydroelectric plants, Dai Ninh and Ham Thuan, to serve the daily life and production of local people in the downstream areas of hydroelectric reservoirs. At the same time, store water resources in Song Luy and Ca Giay reservoirs, not to prolong the time of water collection, causing loss and waste.
Regarding the planting season, the Department of Agriculture and Rural Development noted that for areas with proactive water supply, concentrated planting should be from April 10 to May 15. For the two districts of Duc Linh and Tanh Linh, some areas arrange early summer-autumn crop production to avoid floods (no seasonal crop production), it is necessary to calculate the balance of water resources, the planting season must be concentrated, avoiding planthoppers. For areas that are not fully proactive in irrigation water sources, depending on the local water source situation and weather developments, localities arrange specific crop schedules for each area suitable to their locality, by June 15, the summer-autumn crop planting season will end. In particular, for rice production and other annual crops, localities should guide farmers to prepare well the conditions of seeds and land to be proactive in summer-autumn crop production. Instruct people to implement water-saving irrigation measures; Coordinate with the irrigation works management unit to strictly manage and protect water resources, avoid loss and waste, and use water resources in a balanced manner for favorable and effective summer-autumn crop production.
As of April 15, 2024, the current useful water volume of reservoirs is 104.00 million m3 / 364 million m3 of designed useful capacity, reaching 28.5%. Ham Thuan Hydropower Reservoir has 274.12 million m3 / 522.5 million m3 , reaching 52.46% of designed useful capacity, Dai Ninh Hydropower Reservoir has 121.41 million m3 / 251.73 million m3 , reaching 48.23% of designed useful capacity.
