Risk of water shortage
The drought has been prolonged in recent times and is forecast to continue with complicated and unpredictable developments, making water sources for agricultural production in the summer-autumn crop and aquaculture at risk of shortage. Currently, the water level at the reservoirs is falling and there is a risk of low water level warning, not guaranteeing irrigation water when the drought is severe and prolonged. Hydroelectric reservoirs both produce electricity and regulate water resources downstream for rice production and aquaculture, so there is a risk of shortage at the end of the crop.
These days, the force of engineers, workers at irrigation works, dams to prevent saltwater intrusion Thao Long, Cua Lac ... are assigned to be on duty regularly, maintaining and maintaining items, dredging the flow to ensure operation to cope with drought and salinity for summer-autumn crops and aquaculture. Mr. Van Tri, Head of Cua Lac Salt and Sweetwater Prevention Station, affirmed that the force is following the project regularly, checking and repairing items to ensure good operation according to the functions and tasks set out. against salinity intrusion in rice, vegetable and aquaculture production areas.
Mr. Duong Duc Hoai Khanh, Director of the Provincial Irrigation Works Management and Exploitation One Member Agricultural Company Limited, shared that with the current prolonged and severe drought, irrigation reservoirs are in danger of being exhausted. ensure irrigation service, especially at the end of the crop. The company actively cooperates with localities to prepare plans for drought and saltwater intrusion prevention and control, specifically identifying each area that is likely to lack water to have a plan to combat drought and reasonable water supply measures. . Irrigation stations organize to closely monitor weather changes, water sources, operate irrigation works, prevent salinity, keep fresh water in Thao Long, Cua Lac, and sluices on dykes and rivers to reasonably serve drought prevention. . In particular, note the organization of effective irrigation and water saving right from the beginning of the crop.
Dang Van Hoa, Director of the Provincial Irrigation Sub-Department, informed that, at the request of the Department of Agriculture and Rural Development, departments and owners of irrigation works develop plans to use water sources this summer-autumn crop. compatible with the current state of water resources. The localities and the agricultural sector shall review and assess risks in localities affected by drought, water shortage, and saltwater intrusion to develop detailed response plans for each region and region.
Do not produce at all costs
In the unusually hot and dry weather conditions like this year, the motto of the agricultural industry is not to sow and produce in dry areas at all costs. Accordingly, to arrange the structure of agricultural production, the planting season is suitable with the capacity of water sources, avoid sowing in areas that do not guarantee the initiative in water sources during the whole production season. In particular, focus on arranging crop production areas that are resistant to drought, salinity and demand for water to facilitate water regulation.
Localities mobilize the People, owners of irrigation works, lakes and dams to organize dredging of water intakes, canal systems, embankment of dams to prevent saltwater intrusion, keep fresh water in the canal system, dig ponds to store water, install and operate field pumping stations to make the most of water, reduce water loss and waste. Advanced, water-saving irrigation solutions for rice and upland crops, ensuring to meet the minimum water demand in times of water stress, especially for fruit trees and crops of high economic value … is actively and synchronously deployed.
In order to ensure drought response measures, the agricultural sector, lake and dam owners prioritize investment resources in repairing and restoring irrigation works and concentrated domestic water supply works affected by floods. storms in 2022. At the same time, speed up the construction of irrigation works to improve the capacity of water resource exploitation and the efficiency of irrigation works; develop appropriate construction and diversion plans to ensure that they do not obstruct or obstruct the water supply flow for agricultural production.
Localities make the most of the remaining natural water from ponds, lakes, rivers, streams and canals to supply summer-autumn crop production, combined with strengthening in-field irrigation to restore public operations. affected by the recent flood. Irrigation areas in the downstream areas of rivers with hydroelectric reservoirs need to have a regulation plan to replenish water downstream in dry periods.
For aquaculture, water shortage areas need to increase the use of breeding varieties adapted to drought, water shortage, and saline intrusion. Areas where water sources are not guaranteed, localities actively convert or abandon them, do not organize aquaculture to avoid causing damage to the People. The number of cages and stocking density of fingerlings must be reduced and enhanced with equipment and technical measures on feeding and care for caged fish farming on Bo river, Dai Giang river and O Lau river, combined with harvesting and harvesting. Early planning, harvesting and pruning of commercial aquatic products according to the seasonal schedule.
| In the province, during the beginning of May 5, the weather was complicated and extreme. The phenomenon of intense heat appeared from May 2023-4, 7, especially in the days of May 5-2023, a record heat appeared. In Thua Thien Hue, the highest temperature recorded on May 6 in the delta and Hue city was 7oC, the lowest humidity was 5%. Rainfall in the province in the first 7 months of the year is lower and only reaches 5-40,0% compared to the average of many years. |
