Bananas and climate change

April 17, 2025 By EarthWise Leave a Comment

Bananas are one of the most widely produced fruits globally, with more than 100 million tons grown every year. They are a key export crop worth approximately $11 billion annually. Bananas are also a staple food in many tropical countries, playing a vital role in both the economies of these nations and in global food security.

The Cavendish variety of banana dominates commercial exports, accounting for nearly 47% of global production. However, the Cavendish banana is highly susceptible to diseases like Panama disease, prompting ongoing efforts to develop disease-resistant alternatives. The spread of these diseases is exacerbated by climate change, which alters growing conditions and weakens banana plants. Additionally, climate change poses further threats to the banana industry by impacting crop yields and distribution patterns.

In fact, a new study led by researchers from the University of Exeter in the U.K. has found that by 2080, rising temperatures will make growing bananas for export economically unsustainable in many regions of Latin America and the Caribbean. Colombia and Costa Rica will be among the countries most negatively impacted as they are expected to become too hot for optimal banana cultivation.

The study, which was recently published in the journal Nature Food, found that 60% of the regions currently producing bananas around the world will struggle to grow the fruit unless there are urgent interventions to tackle climate change. The researchers propose several adaptation strategies, including expanding irrigation systems, developing heat- and drought-resistant banana varieties, and helping banana producers manage climate-related risks.

Packing With Banana Leaves

July 25, 2019 By EarthWise Leave a Comment

More and more places are instituting bans on single-use plastic bags. Places like California and Hawaii already have bans in place and New Jersey is considering such a ban. New York’s law will go into effect next March. Supermarkets will no longer provide plastic bags at the checkout line. But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging: wrapping produce in banana leaves. The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam. Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon. Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually. The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean. The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.
