Vietnam is enduring a prolonged heatwave, affecting the lives of its citizens and causing widespread drought.

In recent years, climate change has emerged as one of the greatest challenges facing humanity. Within Southeast Asia, Vietnam is among the nations most severely affected by extreme weather phenomena. Currently, Vietnam is experiencing a prolonged heatwave characterized by continuously rising temperatures across numerous localities, resulting in a host of adverse impacts on people’s livelihoods, agricultural production, water resources, and the ecological environment. Widespread drought conditions not only diminish the quality of life but also pose significant risks to the country’s economy and food security.

Since the beginning of summer, many provinces and cities across Vietnam have recorded temperatures exceeding 40 degrees Celsius. The Central and Northern regions have borne the brunt of this extreme heatwave. High temperatures combined with low humidity have made the weather sweltering and stifling, particularly in densely populated urban centers such as Hanoi, Da Nang, and Ho Chi Minh City.

Meteorological experts attribute these increasingly prolonged and severe heatwaves primarily to the El Niño phenomenon, compounded by the impacts of global climate change. Average temperatures in many regions have risen significantly above historical multi-year averages. The duration of these heatwaves has also lengthened, directly impacting the health and daily lives of millions of citizens.

Amidst these extreme weather conditions, the demand for electricity for cooling purposes has surged. This places immense pressure on the national power grid, raising the risk of localized power shortages in certain areas. Many households are compelled to run fans and air conditioners continuously to cope with the scorching heat, resulting in a sharp increase in living expenses.

The prolonged heatwave has significantly altered the daily lives of residents. In major cities, many people are limiting their outdoor activities during the midday hours to avoid the risks of heat shock and sunstroke. Outdoor workers—such as construction laborers, delivery drivers, street vendors, and farmers—are the group most severely affected.

Sustained high temperatures have led to an increase in hospital admissions for weather-related illnesses. Common conditions include dehydration, heat exhaustion, heatstroke, and respiratory issues. The elderly and young children are the most vulnerable groups during these extreme weather conditions.

Beyond impacting health, the heatwave has also reduced labor productivity. Many construction sites have had to adjust their working hours to avoid the hottest parts of the day. Some schools in regions experiencing excessively high temperatures have had to modify their class schedules or implement enhanced heat-mitigation measures for students.

In rural areas, residents are grappling with a shortage of water for daily use. Many wells have run dry due to the prolonged drought, forcing residents to travel long distances to fetch water or purchase it at high costs. This situation is particularly difficult for impoverished households and those living in remote regions.

Agriculture is one of the sectors suffering the heaviest losses due to the prolonged heatwave and drought. Vietnam is a nation whose economy relies heavily on agricultural production, particularly rice and industrial crops. However, extreme weather conditions have rendered vast areas of arable land arid and resulted in severe shortages of irrigation water.

In the Mekong Delta region, the twin issues of saltwater intrusion and drought are becoming increasingly severe. The depletion of freshwater sources has led to crop failures across numerous rice fields. Fruit crops—such as durian, mango, and citrus—have also been severely impacted by prolonged water scarcity.

Many farmers report that they have been forced to reduce their cultivation areas or switch to drought-resistant crops in order to adapt to the new climatic conditions. However, such crop diversification is not always an easy undertaking, as it requires both capital investment and appropriate technical expertise.

The livestock sector is also facing significant challenges, as excessively high temperatures make cattle and poultry more susceptible to disease and lead to reduced productivity. Shortages of feed and drinking water have driven up production costs, while farmers’ profit margins continue to dwindle.

One of the most severe consequences of the prolonged heatwave is the depletion of water resources. Many irrigation and hydroelectric reservoirs across Vietnam are currently at record-low water levels. This not only impacts the supply of water for domestic use and agricultural production but also affects the power generation capacity of hydroelectric plants.

In many localities across the Central region, rivers, ponds, and lakes have dried up, making it difficult for residents to access clean water. Some areas have been forced to implement water rationing or scheduled water distribution to ensure a sufficient supply for the entire population.

The water shortage also heightens the risk of forest fires during the dry season. Many forests in the Central and Central Highlands regions are currently under a “red alert” due to the excessively hot and arid weather conditions. Authorities have had to intensify patrols and deploy various forest fire prevention measures to mitigate potential damage.

Extreme heat and drought not only impact the daily lives of citizens but also exert negative effects on the national economy. Losses in agricultural production deplete food supplies and hinder Vietnam’s agricultural exports.

Furthermore, electricity shortages—driven by surging demand—can disrupt the production operations of businesses. Many industries that rely on a stable power supply now face the risk of diminished productivity or increased operating costs.

The natural environment also suffers severe consequences. Rising temperatures degrade biodiversity and disrupt ecological equilibrium. Many plant and animal species struggle to adapt to these harsh climatic conditions, leading to a heightened risk of population decline or extinction.

Additionally, air quality in major urban centers has deteriorated due to the urban heat island effect and vehicular emissions. This directly impacts public health and contributes to a rise in respiratory-related illnesses.

In light of increasingly severe extreme weather conditions, the Vietnamese government and local authorities have implemented various measures to mitigate the impacts of heatwaves and droughts.

One key solution involves strengthening the management and efficient utilization of water resources. Many localities have constructed water storage facilities, upgraded irrigation systems, and encouraged residents to conserve water in both their daily lives and production activities.

In the agricultural sector, the adoption of water-saving irrigation technologies and the transition to drought-resistant crop varieties are being vigorously promoted. Experts also advise farmers to adjust their seasonal planting schedules to adapt to the new climatic conditions.

Furthermore, the planting of trees and the development of urban green spaces are regarded as effective solutions for lowering ambient temperatures and improving air quality. Public awareness campaigns regarding climate change also play a crucial role in encouraging the community to join hands in protecting the environment.

In the long term, Vietnam needs to accelerate the development of renewable energy sources—such as solar and wind power—to reduce its reliance on hydropower and fossil fuels. Concurrently, international cooperation in the field of climate change response is essential for sharing experiences and resources.

A prolonged heatwave and widespread drought are presenting Vietnam with significant economic, social, and environmental challenges. The severe impacts on people’s livelihoods, agricultural production, and water resources demonstrate that climate change is no longer a distant future concern, but has become a tangible reality in our lives today.

To mitigate damage and adapt to increasingly harsh climatic conditions, close coordination among the government, businesses, and the public is essential. Fostering environmental awareness, promoting sustainable resource use, and investing in adaptive solutions will be key to helping Vietnam overcome the challenges posed by climate change in the future.
