Climate change killing Bananas

Date: 29 April 2022 Tags: Agriculture

Issue

Research says that rising temperatures across the globe due to climate change can spell doom for banana.

 

Background

Banana is one of the most popular and easily accessible fruit in India as well as the world.

 

Details

  • Till now, global warming has helped increase banana yield in the world since the 1960s. It has seen an average increase of 1.37 tonnes per hectare in 27 countries.

  • But continued increase in temperature could slow down yields and in some cases reduce the yields by the year 2050.

 

Banana farming in India

  • India is the world’s number one producer of bananas with 29 million tonnes produced between 2010 and 2017. More than 29 percent of world’s bananas are sourced from India.

  • Currently, the average yield per hectare in India is 60 tonnes. This could start declining by the year 2050.

  • To prevent this from taking place, investments have to be made to prepare tropical agriculture for future climate change.

 

Cultivation in world

  • Banana is grown in 120 countries across the tropics and subtropics from South America to Africa to Southeast Asia.

  • Even though there are more than 1000 varieties of the crop, highly popular Cavendish cultivar accounts for nearly half of all banana production.

 

Implication of banana yield reduction

  • Banana is a cheap and staple food for 400 million people across the world. Loss of yield will have effects on food security.

  • Many poor countries in Africa, Central America and Caribbean are dependent on banana cultivation. Their revenues and livelihoods will be affected.

 

Prevention of side-effects

The strain on agriculture caused due to climate change has to be negated through technology-driven measures such as irrigation techniques.

 

Other threats for bananas

  • Several strains of a fungus and bacteria are posing grave threats to the world’s banana plants. If left unchecked, it could wipe out the planet’s entire crop within years.

  • Bananas are grown from shoot cutting and hence they are genetical clones. A single disease can destroy the entire species.
