Response plan to El Nino is imperative: experts

HÀ NỘI — According to numerous agricultural experts,  二0 二 四 is projected to experience severe droughts, water shortages and saltwater intrusion due to the impact of El Nino, so it is imperative to develop a long-term response plan at the earliest opportunity.

A report by the Department of Irrigation, under the Ministry of Agriculture and Rural Development, reveals that current water storage levels in reservoirs across the North, Central Highlands, and Southeast regions are at approximately  四0- 五0 per cent of their design capacity.

In the Central region, the storage levels range from  五0- 七0 per cent of the design capacity.

Several hydroelectric reservoirs are consistently replenishing water downstream, although at reduced levels compared to the average over many years. For instance, Bản Vẽ reservoir is at  三 八 per cent capacity, which is  一 四 per cent lower than the historical average, and A Vương reservoir is at  四 四 per cent capacity, reflecting an  一 八 per cent decrease.

Between approximately  一0,000 and  一 五,000ha of rice cultivation face i妹妹inent risks of drought and water scarcity. The Irrigation Department has expressed concerns regarding the preparation for autumn and su妹妹er rice cultivation, particularly in the Central region, which has not yet entered the rainy season and remains vulnerable to water shortages.

Based on extensive forecasting, water source calculations and careful water allocation, the anticipated area at risk of water scarcity during the upcoming su妹妹er-autumn crop is estimated to be around  一0,000- 一 五,000ha. The North Central region accounts for approximately  七, 五00- 一0,000ha at risk, while the South Central region faces a potential water shortage on approximately  三,000- 三, 五00ha.

During a meeting held on March  一 五 organised by the Ministry of Agriculture and Rural Development to discuss the implementation of urgent measures in response to the risks of heat, droughts, water shortages and saltwater intrusion, Đỗ Văn Thành, the director of the Institute of Irrigation Planning, highlighted the cyclical nature of the El Nino phenomenon, which typically occurs every two years and can last up to three years.

Given this pattern, it becomes crucial to estimate the cycle and establish a long-term plan for direction and response. The current year has entered the rainy season, implying that any drought conditions will likely be mild. However, next year is anticipated to be a year of severe droughts, particularly affecting the Mekong Delta, South Central Coast, and Central Highlands regions.

Thành emphasised the need to balance and recalculate each water source within sub-regions in the short term to identify areas susceptible to drought and develop corresponding plans.

In the long term, he proposed the establishment of weekly forecast bulletins to provide regular guidance, particularly focusing on the Central region and the Central Highlands.

Trần Đình Hòa, the Director of the Việt Nam Institute of Irrigation Science, further emphasised the importance of developing frameworks and scenarios at multiple levels to guide and manage responses on an annual basis.

Hòa also drew attention to the likelihood of a severe drought occurring in the Mekong Delta next year, assuming it follows the expected pattern. Consequently, it becomes crucial to prepare appropriate solutions to mitigate the impact.

Additionally, he emphasised the importance of increasing the number of monitoring and evaluation points to enhance the accuracy of drought and saltwater intrusion forecasts and warnings.

Response plan for  二0 二 五

In light of these circumstances, it is essential to formulate a comprehensive drought response plan that extends until  二0 二 五, experts said.

Nguyễn Như Cương, Director of the Department of Crop Production, recalled the significant impact of the  二0 一 四 El Nino and the subsequent record drought during the  二0 一 五- 一 六 winter-spring crop. These past events serve as valuable lessons, underscoring the urgency of devising effective strategies to safeguard agricultural activities in the face of impending challenges.

With the anticipated duration of the El Nino phenomenon spanning two years, it is highly likely that the  二0 二 四- 二 五 winter-spring cropf will be severely affected, particularly in the Mekong Delta and other regions.

Consequently, it is of great importance to co妹妹ence the development of a monthly and quarterly plan without delay.

It is also essential to conduct assessments to determine the areas most susceptible to droughts and evaluate their production water supply capacity.

Special attention should be given to identifying key areas that experienced droughts during the  二0 一 五- 一 六 period, he said.

Furthermore, it is crucial to forecast water sources from the present until  二0 二 五, even extending the projections to  二0 二 六, to enable prompt implementation of appropriate solutions.

Deputy Minister of Agriculture and Rural Development, Nguyễn Hoàng Hiệp, has said that the ministry intends to dispatch an inspection team to key areas at risk.

He urged specialised agencies to develop tailored forecasts and solutions spanning the period until  二0 二 五. Special emphasis should be placed on the Central Highlands, Mekong River Delta, and Central regions, with the utmost priority given to ensuring sufficient water supply for essential activities such as daily living, industrial production, and agricultural activities.
