people affected and 1.5 million people severely affected
As a result, a total of 7.7 million people were affected by the disruption to basic services (electricity, communications, transport, water, health, education and civil protection) and food supplies, and 291 lost their lives. Crops, livestock and lifeline infrastructure were severely damaged or completely lost, hampering the delivery of aid relief to the affected communities. Although Viet Nam is a country recognized as being exposed to recurring hazards, the magnitude and consecutive characteristics of the storms worsened the hardships caused by the ongoing pandemic and further plunged the affected people into poverty. Following the nine storms, the Government of Viet Nam introduced a new classification level for heavy rain in their weather warning system. Viet Nam has been listed by the World Bank as one of the five countries that will be worst-affected by climate change. Around 11.8 million people living in the coastal provinces of Viet Nam are exposed to intense flooding.
In some provinces the flood levels broke historic records. Increasing extreme events severity and flooding will challenge many tropical coastal locations globally.
Need to consider and prepare for new, unseen climate extremes. The proportion of Category 4 and 5 tropical cyclones and associated average precipitation rates are projected to increase with a 2°C global temperature rise. Coastal hazards will be exacerbated by an increase in the average intensity and magnitude of storm surges, and precipitation rates of tropical cyclones.
The number of intense storms and cyclones is expected to increase with the changing climate, making these types of scenarios more likely in the future.
