Impact of Rainy Season on Human Lives and Environment

The rainy season often brings happiness to people living in two-season countries. This season creates a nice change after months of dry and hot weather. However, rain can cause people to experience some challenges. Moreover, the negative impact of rainy season also affects the environment.

Therefore, they must be prepared for the rainy season. In addition, governments in those countries must improve their disaster mitigation plan annually. This is because climate change is getting worse each year. Consequently, it can intensify the negative impact of the rainy season.

Positive Effects of Rainy Season

During the rainy season, rain falls almost every day at different intensities. Some days, it falls in low intensity for less than an hour. Other days it may rain heavily for hours. Despite the different precipitation levels, this season offers many advantages.

1. Water Resources

Rain is crucial in refilling water resources. During the dry season, aquifers, lakes, and rivers run out of water because of the low rainfall. However, the rainy season brings lots of rainfall. Therefore, these water resources are full of water again. Consequently, they can provide water for irrigation, drinking, etc.

Moreover, rain helps the earth in storing water in the form of groundwater, glaciers, and snow. Rain also plays an essential role in regulating the water cycle, which is crucial to all living creatures.

2. Improve Air Quality

The second positive impact of rainy season is improved air quality. Rains wash away sediments and pollutants from the environment. Therefore, the air is cleaner and fresher in this season. 

3. Ecosystem Support

The rainy season is one of the best ecosystem supports. Rainwater helps plants and animals maintain their health and diversity. Moreover, rain reduces the effects of the heat on plants, animals, and humans. Rain also maintains life balance in rainforests, wetlands, and forests.

The Negative Impact of Rainy Season

However, the rainy season can be harmful to humans and the environment. These effects especially arise when heavy rain falls for hours. In addition, the impact of this season is more severe in urban areas and densely populated regions. 

Below are the effects of the rainy season.

1. Floods

Torrential rains can result in floods. In densely populated areas, excessive water from heavy rains cannot flow smoothly. Therefore, floods will develop in those places.

Sometimes, rivers, dams, and other flood management systems cannot contain the rainwater. Consequently, rainwater overflows areas near those systems.

Floods can cause various problems. They damage infrastructures, kill or displace people, contaminate drinking water, and cause financial loss. Moreover, floods affect transportation and businesses.

2. Landslides

Another common impact of rainy season is an increased risk of landslides. Hills and sloping areas are in danger of landslips during torrential rains because rains saturate the ground. The water absorbed by the soil then increases in pressure and disrupts the stability of the ground.

As a result, the sloping ground slides down. This catastrophe typically results in loss of lives, damaged buildings, power outages, and disrupted communication and transportation. Moreover, landslides will cause animals to lose their habitats and ecosystems.

3. Crop Damage

Excessive rain during the rainy season can cause soil erosion. Consequently, crops cannot get enough nutrients from the soil. Torrential rains may also affect pollination and fertilization of crop flowers.

These factors may lead to reduced yields. Consequently, farmers will experience a financial loss. On the other hand, societies may have difficulties in purchasing groceries due to increased prices and low supplies.

4. Diseases

Most people have a higher risk of suffering from various health issues during the rainy season. Puddles or inundated areas are excellent breeding grounds for dengue, malaria, chikungunya, and other vector-borne diseases.

In addition, torrential rains increase the risk of water contamination in waterways.  Contaminated water supplies can cause people to suffer from diarrhea, cholera, hepatitis A, and other waterborne diseases.

Moreover, mold typically grows in flooded or wet houses during the rainy season. Mold exposure can cause respiratory problems.

Preventing the Negative Impact of the Rainy Season

Rains are good for humans and the environment if they are in moderate intensity. However, climate change has altered the rain pattern and caused more disasters during the rainy season. Therefore, governments must develop disaster mitigation plans to prevent the effects of the rainy season.

These plans must include a cell broadcast alert system. This alert system is excellent at disseminating disaster early warnings. Therefore, people in the affected areas can save themselves and their belongings before the disaster strikes.

Moreover, governments must take measures to improve their flood management and drainage systems. They must also promote sustainable farming practices and prevent deforestation.

The impact of rainy season can be potent. It affects the economy and may kill people. Therefore, governments must broadcast early warning messages when this impact is about to happen. They can use Hitech Terminal to disseminate these alerts. This tool is effective and resilient in sending warnings.
