Tree-Lined Streets Offer Respite as Ho Chi Minh City Swelters

Ho Chi Minh City's tree-lined streets are providing a welcome escape from the searing heat that has gripped the city since late March. With daily temperatures exceeding 35 degrees Celsius, the lush greenery is creating a cooler environment for commuters, making their daily journeys more tolerable during the sweltering conditions.

Why this matters: The impact of urban heat islands on cities worldwide is a pressing concern, as they exacerbate the effects of climate change and negatively affect the health and well-being of urban residents. By incorporating green spaces into urban planning, cities can mitigate these effects and create more sustainable and livable environments.

On a recent morning, a brief rainfall surprised many in Ho Chi Minh City. The five-minute downpour caused temperatures to drop by 3-4 degrees Celsius, offering a fleeting reprieve from the oppressive heat wave. Motorcyclists quickly took shelter under awnings when the unexpected shower passed through.

Le Dinh Quyet, head of the meteorological forecasting department at the Southern Regional Hydrometeorological Station, attributed the short-lived rainfall to atmospheric disturbances. While hot weather is predicted to return by noon, Quyet expects the intensity of the heat to decrease soon, with temperatures no longer reaching the blistering 39-degree Celsius mark. He forecasts that rainfall will arrive from May 4-5 onwards, further helping to lower temperatures.

The ongoing heat wave, which began on March 29, has persisted longer than previous ones, marking a record since 1997. Ho Chi Minh City and the southern region are approaching the end of the dry season, which typically spans from late November to late May. The area has endured severe heat phases this year, exacerbated by the El Nino phenomenon that has led to reduced rainfall across Vietnam, especially in the Central Highlands and southern regions.

In a welcome development, heavy rains have recently brought relief and much-needed water to rice and fruit crops in several Mekong Delta provinces following an extended dry spell. The Central Highlands has also experienced scattered rainfall in recent days. However, the meteorological agency has cautioned people about the high impurity levels in these unseasonable rains.

As Ho Chi Minh City confronts the challenges posed by climate change and rapid urbanization, its tree-lined streets are playing a vital role in combating the urban heat island effect. The high density of vehicles and concrete surfaces in the city exacerbates this phenomenon. The presence of trees and greenery not only provides shade and improves air quality but also contributes to reducing the overall temperature, positively influencing the life expectancy of the city's residents.

Despite occupying a mere 3% of the Earth's surface, cities are responsible for a staggering 70% of energy-related CO2 emissions. To counterbalance this, urban areas can incorporate more trees and greenery into their environments. The Miyawaki method, an innovative approach to forest planting, offers the potential to restore native forests within a matter of decades. These forests play a vital role in absorbing carbon dioxide, making them indispensable in counteracting emissions.

Other cities worldwide, such as Warsaw and Paris, are also implementing urban greening initiatives to reduce CO2 emissions and increase resilience against frequent summer heat waves. These measures include expanding tree-lined streets and cycling infrastructure. By adopting such strategies, Warsaw aims to achieve a remarkable reduction of 1 million tonnes in CO2 emissions.

Ho Chi Minh City's tree-lined streets serve as a demonstration of the importance of integrating nature into the urban fabric. By providing respite from the intense heat and contributing to the well-being of its residents, these green oases offer hope in the face of rising temperatures and environmental concerns. The city's continued efforts to address the complexities of climate change and rapid development will depend on its dedication to preserving and enhancing its urban greenery, a key factor in creating a more sustainable and livable future for all.
