This leads to stunted plants and decreased overall yield.

Furthermore, submerged rice plants are susceptible to diseases and pests, resulting in poor-quality grains with reduced market value.

Typhoon or hurricane influence

The destructive potential of typhoons and hurricanes lies in their strong winds and heavy rainfall.

These weather events can cause severe structural damage to rice fields, uprooting plants and leaving them irreparably damaged.

The physical destruction of crops leads to major yield losses for farmers, impacting their livelihoods.

Moreover, the floodwaters brought by typhoons and hurricanes pose contamination risks.

These waters can carry pollutants, such as industrial waste, pesticides, and sewage, which infiltrate the rice fields.

As a result, the grains become contaminated, jeopardizing their safety and quality.

This contamination not only affects the local rice market but also poses health risks to consumers.

In essence, weather extremes significantly affect rice production, both in terms of yield and grain quality.

Drought, floods, and typhoons/hurricanes all pose unique challenges to rice farmers, leading to decreased yields and compromised market value.

It is crucial for farmers and policymakers to implement strategies and interventions that can mitigate the impact of these weather extremes on rice production, ensuring food security and sustainable agricultural practices.
