Challenges: Pests, Climate Change & Nepal’s Orange Future
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
Keyword: citrus pest problems in Nepal
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
Keyword: climate change effect on orange farming
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.
