Challenges: Pests, Climate Change & Nepal’s Orange Future

Nepali oranges—locally known as Suntala—are not just seasonal fruits. They represent the livelihood of thousands of farmers across the hilly regions of Nepal. But despite their growing popularity in domestic and international markets, Nepal’s orange farming faces serious challenges.

From rising pest attacks to unpredictable weather patterns, the future of Nepali orange production is at risk. In this blog, we’ll explore the main challenges Nepali orange farmers face and what steps can be taken to protect this vibrant citrus industry.

🌾 A Quick Look at Orange Farming in Nepal

Nepali oranges are mainly grown in mid-hill districts like:

  • Dhading

  • Ramechhap

  • Sindhuli

  • Lamjung

  • Gulmi

  • Salyan

  • Syangja

These regions have traditionally offered the ideal altitude, temperature, and soil for Mandarin oranges. However, in recent years, many farmers have reported declining yields and increasing threats.

🐛 1. Rising Pest Attacks

One of the biggest threats to orange farming is the rise in insect pests and citrus diseases, especially:

  • Citrus fruit fly

  • Citrus greening (Huanglongbing/HLB)

  • Stem borer

  • Leaf miner

These pests can:

  • Cause early fruit drop

  • Damage the tree’s immune system

  • Lower fruit quality and market value

Many small farmers lack the resources for proper pest control, organic sprays, or training in modern farming techniques.

🔥 2. Impact of Climate Change

Nepal’s changing climate is making orange farming increasingly difficult. The key problems include:

  • Irregular rainfall: Disrupts flowering and fruit setting

  • Longer droughts: Stress trees and reduce fruit size

  • Unseasonal hailstorms or frost: Damage flowers and ripening oranges

  • Warming winters: Affect the flavor and sugar balance in oranges

These environmental shifts are forcing farmers to adjust planting times, shift to higher altitudes, or give up orange farming altogether.

👨‍🌾 3. Aging Trees and Lack of Orchard Management

Many orange trees in Nepal are over 20–30 years old, making them less productive. Without:

  • Proper pruning

  • Soil replenishment

  • Pest/disease management

  • Training in modern horticulture

…yields drop drastically, and the quality of fruits decreases.

💰 4. Poor Market Access & Price Fluctuation

Even when the harvest is good, farmers often struggle to:

  • Get fair prices from middlemen

  • Transport oranges to cities due to poor road access

  • Store unsold fruit due to lack of cold storage facilities

This leads to post-harvest loss, discouraging orange cultivation.

🌿 5. Lack of Government Support & Research

While there are agricultural programs, limited on-ground implementation, lack of research on climate-resilient orange varieties, and insufficient support for organic certification and export marketing slow down progress.

🔮 What’s the Future of Nepali Oranges?

Despite the challenges, the future isn’t all bleak. With the right strategies, Nepal can protect and grow its orange industry:

✅ What Needs to Happen:

  • Integrated pest management (IPM)

  • Climate-smart farming techniques

  • Training on pruning, grafting, and organic practices

  • Building cold chains and rural collection centers

  • Promoting orange-based processing (juice, jam, dried peels)

  • Investment in research and resilient citrus varieties

🧡 Why It Matters

Nepali oranges are not just fruits—they represent:

  • Rural income

  • Local biodiversity

  • Organic, chemical-free produce

  • Export potential in South Asia and the Middle East

Preserving orange farming means preserving a way of life for thousands of Nepali households.
