Climate Change Is Threatening India's Exotic Fruits Like Kiwi, Avocado and Dragon Fruit

India's appetite for exotic fruits such as kiwi, avocado, dragon fruit and passion fruit has grown rapidly over the past decade. Once considered luxury imports, these fruits have become staples in health-conscious diets while offering farmers better returns than many conventional crops.

However, scientists warn that climate change is increasingly threatening the future of these high-value crops, with rising temperatures, erratic rainfall and extreme weather affecting their growth, flowering and yields.

Climate change is hitting India's exotic fruit farms

According to horticultural experts, warming temperatures and unpredictable weather patterns are beginning to impact fruit production across India.

While exotic fruits have been promoted as climate-resilient alternatives in some regions, researchers say they are far from immune to global warming.

Increasing heat stress, changing rainfall patterns and prolonged dry spells are reducing productivity and making cultivation more challenging.

Dragon fruit: Heat is becoming a major challenge

Dragon fruit is widely known for its drought tolerance and relatively low water requirement.

However, scientists at the ICAR-Indian Institute of Horticultural Research (IIHR) say prolonged temperatures above 36°C to 40°C can severely damage the crop.

Excessive heat can lead to:

• Sunburn on stems and fruits
• Reduced flowering
• Poor fruit set
• Yield losses of 30% to 60% if unmanaged

Researchers have developed climate adaptation techniques such as:

• Kaolin-based protective sprays
• Artificial shading systems

These methods help lower plant temperatures and minimise sunburn damage.

Kiwi cultivation faces rising temperatures

Unlike dragon fruit, kiwi thrives in cooler climatic conditions.

Researchers say prolonged heatwaves interfere with:

• Photosynthesis
• Fruit development
• Overall yield
• Fruit quality

Scientific studies suggest traditional kiwi-growing regions could become less suitable in the future unless farmers adopt:

• Heat-tolerant varieties
• Climate-smart orchard management
• Improved cultivation practices

Passion fruit and avocado are also under pressure

Passion fruit grows best under stable temperatures and adequate soil moisture.

Experts say rising temperatures and erratic rainfall can:

• Disrupt flowering
• Reduce fruit development
• Lower productivity

This makes efficient irrigation and water management increasingly important.

Avocado cultivation also faces challenges as changing weather conditions affect orchard health and long-term productivity.

Extreme weather is increasing farming risks

Scientists say climate change is not just about rising temperatures.

More frequent extreme weather events are creating additional challenges for fruit growers, including:

• Heatwaves
• Heavy rainfall
• Extended droughts
• Unseasonal rain

These weather extremes can have serious consequences.

During flowering

Unexpected rainfall can reduce pollination and lower fruit production.

During heavy rains

Excess moisture encourages fungal diseases and damages orchards.

During prolonged dry spells

Young plants experience severe water stress, affecting growth and future productivity.

Why fruit orchards are especially vulnerable

Unlike seasonal crops, fruit orchards require years of investment before reaching full production.

A single season of extreme weather can impact:

• Current harvests
• Tree health
• Future yields
• Farmer income

As a result, climate risks for orchard farmers are often long-lasting.

How farmers can adapt

Researchers say the future of India's exotic fruit cultivation will depend on climate adaptation rather than simply introducing new crops.

Key adaptation measures include:

• Developing heat-tolerant fruit varieties
• Installing protective shade structures
• Improving irrigation efficiency
• Better orchard management
• Scientific water conservation practices

These measures can help reduce climate-related losses and improve long-term resilience.

What it means for consumers

For now, supermarket shelves continue to display colourful exotic fruits throughout the year.

However, experts warn that climate change could eventually affect:

• Availability
• Prices
• Quality
• Long-term production

The challenge is no longer just growing exotic fruits but ensuring they remain sustainable in an increasingly warmer climate.

Key Highlights

• Climate change is affecting the cultivation of kiwi, avocado, dragon fruit and passion fruit in India.
• Dragon fruit can suffer 30-60% yield losses during prolonged temperatures above 36°C-40°C.
• Kiwi cultivation is increasingly threatened by rising temperatures and heatwaves.
• Erratic rainfall, droughts and extreme weather are disrupting flowering and fruit production.
• Scientists recommend heat-tolerant varieties, shading, efficient irrigation and climate-smart farming practices.

FAQs

How is climate change affecting exotic fruits in India?

Rising temperatures, erratic rainfall and extreme weather are reducing fruit yields, affecting flowering and increasing crop stress.

Which exotic fruits are most vulnerable?

Kiwi, dragon fruit, avocado and passion fruit are among the crops facing increasing climate-related challenges.

Why is dragon fruit affected despite being drought tolerant?

Although dragon fruit requires less water, prolonged temperatures above 36°C-40°C can cause sunburn, reduce flowering and significantly lower yields.

How can farmers protect exotic fruit crops?

Experts recommend heat-tolerant varieties, protective shading, efficient irrigation, water management and climate-smart orchard practices.

Will climate change affect fruit prices?

If production declines because of extreme weather, consumers could eventually see higher prices and reduced availability of some exotic fruits.
