For the coffee growers of Chikmagalur, every harvest season used to bring not just the joy of ripe cherries, but the quiet dread of the unpredictable sky. Today, a gleaming solar tunnel dryer is rewriting that story: One perfectly dried bean at a time.

Picture a coffee farmer in the misty hills of Chikmagalur, Karnataka. For months, she has tended her plants with patience and care. When harvest season arrives, the cherries are plump, the aroma rich. But then the clouds gather. The rain comes early. The carefully laid-out drying beds are drenched overnight, and with them, weeks of work are washed away. This is not a rare occurrence. For smallholder coffee growers across India’s Western Ghats, it is a recurring heartbreak.

But for the more than 50 farmers affiliated with Hirehadlu Farmers Producer Company (a Fairtrade-certified Small Producer Organisation (SPO) in Koppa, Chikmagalur) that story is changing. Thanks to a transformative initiative under Fairtrade NAPP’s Coffee Development Plan (CDP), a state-of-the-art solar tunnel dryer now stands at the heart of their community, ready to protect not just the coffee, but the livelihoods of every family who grows it.

The Old Way: Drying at the Mercy of the Weather

Drying coffee is not simply a mechanical step, it is an art that directly determines the quality, flavour, and market value of the final cup. After harvesting, coffee cherries must have their moisture reduced to around 10–12% for safe storage and optimal taste. Get it wrong, and mould creeps in, mycotoxins develop, and a season’s hard work is lost.

For generations, smallholder farmers in Karnataka have relied on open sun drying, spreading beans on tarpaulin sheets or raised beds, hoping the weather would cooperate. While cost-effective in theory, this method is deeply vulnerable to the one thing farmers cannot control: the climate. Unpredictable rains, rising humidity, and erratic sunshine, all symptoms of a changing climate, make traditional sun drying increasingly unreliable. The result is uneven drying, contamination, and post-harvest losses that chip away at incomes year after year.

A Journey of Discovery: The Exposure Visit That Sparked Change

The seeds of change were sown in 2025, when Fairtrade NAPP organised an exposure visit to various drying facilities across Karnataka led by Dr. Gopinandan, a scientist from the Central Coffee Research Institute (CCRI). Farmers from Hirehadlu and other farmers organisation were invited to see and ask questions about mechanical dryers and solar tunnel dryers, etc that had remained distant concepts until then.

For the members of Hirehadlu Farmers Producer Company, the solar tunnel dryer was a revelation. The science was elegant in its simplicity: a long, enclosed, tent-like structure that traps solar heat, raises the internal temperature by 15–30°C above the ambient level, and uses fan-driven air circulation to dry produce quickly, evenly, and hygienically. No fuel. No heavy electricity bills. Just sunlight, thoughtfully channelled.

The SPO expressed immediate interest. Under the  Fairtrade NAPP’s Coffee Development Plan, which supports certified coffee SPOs through training, technology access, and asset creation, this  was exactly the kind of investment it was designed to enable.

A Shared Investment in a Shared Future

What followed was a demonstration of the Fairtrade model at its best: a match funding partnership between Fairtrade NAPP and Hirehadlu Farmers Producer Company.

The installation was handled a reputable vendor based in Chikmagalur district, with a track record in agricultural solar technology. The unit was set up at Golgar, Kesave Post, Koppa, a location chosen by the SPO for its accessibility to the farming community. By December 2025, the dryer was installed and operational. A few weeks later, on 27th January 2026, the community gathered to inaugurate it. The board of directors, local farmers, and Fairtrade NAPP representatives all present to mark this quiet but significant moment.

The Dryer in Action: What It Means for the Coffee

The solar tunnel dryer at Hirehadlu is built to handle up to 1,000 kilograms of coffee at a time. It is not just its capacity that makes it remarkable, it is the quality of what comes out the other side. The enclosed structure shields the beans from dust, insects, birds, and animals. The consistent heat and airflow prevent microbial spoilage. And because it operates even in rainy or overcast conditions, the drying calendar is no longer held hostage to the weather.

Where traditional open drying could take days or even weeks of anxious watching, the solar dryer dramatically reduces drying time, and does so with a consistency that open sun simply cannot match. The result is better colour, better flavour, and a bean that commands better prices at market. For smallholder farmers who depend on every kilogram, this difference is not small. It is the difference between a good year and a struggling one.

Designed to last 15–20 years with minimal maintenance, this is not a short-term fix. Built with free solar energy, requiring no ongoing fuel costs, and scalable to a wide range of agricultural produce beyond coffee, it is a long-term asset for the community.

More Than a Machine: A Step Towards Climate Resilience

The installation of this solar dryer speaks to something larger than a single piece of equipment. It is part of Fairtrade NAPP’s long-term commitment to supporting smallholder coffee farmers in the face of a changing climate. Under the Coffee Development Plan, NAPP works hand-in-hand with certified SPOs to build the skills, technologies, and systems that make farming ecologically and economically sustainable.

More than 50 farmers in and around Koppa will benefit directly from this dryer. For each of them, it represents something specific: fewer losses, more consistent quality, reduced energy costs, and a little less anxiety when the monsoon arrives. It represents the kind of practical, grounded progress that Fairtrade is built to deliver.

A Moment to Celebrate: Inauguration by the Board

On 27th January 2026, the Hirehadlu Farmers Producer Company together will NAPP officials inaugurated the new solar tunnel dryer. The ceremony was led by Mr. Uday Kumar, a Board of Director of the SPO, who cut the ribbon alongside fellow board members and beneficiary farmers.

The atmosphere was one of quiet pride. Farmers standing beside something they had helped build, something that belonged to them, and something that would serve their community for decades to come.

Looking Ahead: A Model Worth Replicating

The story of the Hirehadlu solar dryer is, at its heart, a story about what happens when communities are trusted and supported to invest in their own futures. Fairtrade NAPP did not simply hand over a machine. It created a space where farmers could learn, decide, co-invest, and take ownership, and that makes all the difference.

As climate pressures continue to intensify across South and Southeast Asia, the need for climate-resilient, farmer-led solutions will only grow. The solar tunnel dryer at Hirehadlu offers a model that is practical, affordable, sustainable, and replicable. It is a small but powerful proof that Fairtrade’s approach to development works not in spite of putting farmers first, but precisely because of it.
