Kenya’s New Potato Frontier: Can High-Altitude Varieties Solve Food Security and Farmer Profitability Woes?

As Kenya’s maize belt continues to struggle with shrinking yields, unpredictable rainfall, and rising production costs, a quiet revolution is brewing in the highland counties—one rooted not in maize or wheat, but in potatoes. Known locally as “waru”, this tuber crop has rapidly emerged as both a staple and a cash crop for thousands of smallholder farmers, especially in cool, high-altitude regions like Nyandarua, Meru, Elgeyo Marakwet, Bomet, and Narok.

With strategic support from government agencies, NGOs, and agri-tech startups, Kenya is now betting on improved potato seed systems and modern farming practices to revive the sector and ease pressure on over-relied cereal crops.

A Crop with National Significance

Though often overlooked in national food narratives, potatoes are Kenya’s second most important food crop after maize. According to the Ministry of Agriculture’s 2024 Crop Production Report, Kenya produced over 1.5 million tonnes of potatoes last year, grown by about 800,000 small-scale farmers on 158,000 hectares of land.
And yet, the sector is underperforming. National yields average just 8–10 tonnes per hectare, far below the potential 25–35 tonnes seen in countries like the Netherlands or Egypt. Why? The main culprit: poor-quality seed.

The Seed Problem

Over 90% of potato farmers in Kenya plant recycled seed—tubers saved from previous harvests or bought informally at local markets. This practice results in seed degeneration, increased disease incidence (especially bacterial wilt and viral infections), and dismal yields.

In 2025, the Kenya Agricultural and Livestock Research Organization (KALRO), in collaboration with CIP (International Potato Center) and the Seed Potato Council of Kenya, is scaling up efforts to address this. Certified seed producers like ADC Molo, Kevian Kenya, and Apical Ltd. have been contracted to produce disease-free seed tubers of high-yielding, locally adaptable varieties.

Some of the most promising potato varieties now promoted include:

• Shangi – Fast maturing, good for chips and boiling.
• Unica – Drought-resistant with good storability.
• Wanjiku – Late blight-tolerant and suitable for baking.
• Taurus – High-yielding with uniform tuber size.

These varieties are developed with high altitude conditions in mind, thriving between 1,800–3,000 meters above sea level.

Government Strategy and Devolution in Action

The Ministry of Agriculture launched the National Potato Strategy 2023–2033, which aims to triple certified seed production, introduce digital traceability, and support mechanization and storage.

At county level, key potato zones like Nyandarua and Nakuru have established potato aggregation centers, cold storage facilities, and value addition hubs, funded in part by the European Union and the World Bank through the National Agricultural Value Chain Development Project (NAVCDP).

“With cold storage, I no longer rush to sell at throwaway prices,” says Peter Kariuki, a farmer in Ol Kalou. “I can now wait until market prices improve.”

Technology and Innovation Driving Change

Agri-tech companies like Digifarm, Twiga Foods, and iShamba are integrating potato farmers into digital ecosystems. Using simple SMS platforms, farmers now access:

• Market prices and buyer contacts
• Weather alerts
• Soil testing services
• Advice on pest and disease management
• Seed ordering platforms

Recently, a new mobile app dubbed “WaruSmart” is being piloted in Nyeri and Kericho to provide geo-specific guidance on potato variety selection, planting dates, and spacing guidelines.

Value Addition: Moving Beyond Fresh Potatoes

Kenya’s potato value chain is largely informal and dominated by brokers. However, the tide is turning with increased investment in processing:

• Frozen chips and crisps factories have sprung up in Naivasha, Thika, and Eldoret.
• Dehydrated potato products for export are now produced by Kevian Foods and Norbrook Africa.
• Local cottage industries are producing potato flour used in baking and porridge for children.

Such diversification is helping to reduce postharvest losses, estimated at 25–40% in traditional supply chains.

Youth and Women Participation

Potato farming is increasingly attracting young agripreneurs. In Narok and Nyandarua, youth groups are using mini-tractors, planters, and harvesters on leased land to grow potatoes commercially. Organizations like SNV Kenya and AGRA are funding youth-led cooperatives to train on modern seed multiplication, greenhouse seed production, and marketing.

Women groups are also embracing value addition, especially in Taita Taveta and Bomet, where they package peeled, precooked potatoes for urban markets.

Environmental Sustainability and Climate Adaptation

Modern potato farming is not without its challenges. Soil degradation, pesticide overuse, and water pollution from synthetic fertilizers remain concerns. As a result, conservation agriculture is being promoted:

• Minimum tillage to protect soil structure
• Use of organic compost and vermiwash instead of synthetic fertilizers
• Rainwater harvesting tanks for irrigation in rain-deficit zones
• Promotion of indigenous biopesticides such as neem and chili-based sprays

KALRO is also working with CGIAR researchers to develop climate-smart potato clones with enhanced drought and heat tolerance, ensuring adaptability even in changing agro-ecological zones.

Market Potential and Export Opportunities

Kenya’s growing urban population, changing dietary habits, and demand for fast food have made potatoes a strategic staple. Consumption of chips alone has risen by 38% between 2019 and 2024, according to a market study by Euromonitor.

In addition, Kenya is eyeing export markets in East Africa, especially Uganda, Rwanda, and South Sudan, where demand for processed potato products is high. However, to scale this, Kenya must address:

• Inconsistent quality standards
• Lack of cold chain logistics for exports
• Limited harmonization of phytosanitary protocols

The future of Kenya’s agriculture lies not just in maize or beans but in diversifying smartly—embracing crops like potatoes that align with market demand, agroecological suitability, and profitability.

As certified seeds spread, aggregation hubs mature, and value chains strengthen, potato farming may very well become Kenya’s next agricultural goldmine. For the farmers nestled in the misty hills of Nyandarua, Meru, or Bomet, the humble potato is no longer a backup crop—it’s the foundation of rural prosperity.
