Climate change is an existential threat that disproportionately affects tropical countries, where approximately 80% of the population is vulnerable to its adverse effects.

The warming of our planet and shifting weather patterns are undermining the production, distribution, and accessibility of food, thus posing significant challenges to food security in tropical regions.

Main Body:

Reduced Crop Yields:

  • Rising temperatures and erratic rainfall patterns are leading to reduced crop yields in tropical countries like India.
  • Example: Indian rice and wheat crops, which are staple foods, have faced yield reductions due to changing climate conditions.

Total Crop Failure in Extreme Weather Events:

  • Extreme weather events, such as prolonged droughts and severe floods, can result in complete crop failures.
  • Example: Kerala floods in 2018 caused extensive damage to rice, banana, and spice crops, impacting food availability.

Increased Pest and Disease Pressure:

  • Warmer temperatures create favorable conditions for pests and diseases, causing crop losses and reducing food security.
  • Example: The outbreak of Fall Armyworm in India has damaged maize and other crops, affecting food production.

Water Scarcity:

  • Climate change-induced water scarcity disrupts irrigation systems and reduces water availability for agriculture.
  • Example: Declining water levels in the Ganges-Brahmaputra basin impact rice cultivation in India and Bangladesh.

Disruption of Fishing Communities:

  • The increased frequency and intensity of cyclones disrupt coastal fishing communities’ livelihoods.
  • Example: Cyclone Fani in 2019 severely affected fishing activities along the Indian coastline.

Loss of Biodiversity:

  • Climate change contributes to habitat loss and endangers biodiversity, affecting the availability of diverse food sources.
  • Example: The decline in coral reefs in the Andaman Sea threatens fish species that serve as a crucial food source.

Food Price Volatility:

  • Climate-related crop failures and supply chain disruptions lead to food price volatility, making food less affordable for vulnerable populations.
  • Example: Fluctuations in onion prices in India due to weather-related crop losses impact consumers’ access to this essential vegetable.

Migration and Conflict:

  • Climate-induced food insecurity can drive migration and exacerbate conflicts over resources.
  • Example: Displacement of communities in regions like Jharkhand due to water scarcity leading to resource conflicts.


Urgent action is imperative to mitigate climate change’s adverse impact on food security in tropical countries.

Sustainable agriculture practices, emission reduction efforts, and adaptation strategies are essential to safeguard food supplies and ensure resilience for present and future generations.

It is imperative for governments, international organizations, and communities to collaborate in addressing the multifaceted challenges of climate-induced food insecurity in the tropical regions.
