Guatemala

Guatemala has a well-established potato industry centred mainly in the country’s cool, high-altitude regions. Potato production is particularly important in the western highlands, including the departments of Quetzaltenango, San Marcos and Huehuetenango, with additional production in Chimaltenango, Sololá, Quiché, Jalapa and other highland areas. The crop performs well at elevations generally ranging from about 1,500 to 3,600 metres above sea level, where cooler temperatures favour tuber development. These conditions allow potatoes to be grown across different production seasons, depending on altitude, rainfall and irrigation.

Potato farming is closely linked to Guatemala’s smallholder agricultural economy. The crop is grown both for household consumption and as an important cash crop, particularly in the Western Highlands. Quetzaltenango, San Marcos and Huehuetenango account for a large share of national production, while potato cultivation provides income and employment for thousands of rural families, many of them Indigenous farming households. Potatoes are sold through local and regional markets and also contribute to Guatemala’s agricultural trade with neighbouring Central American countries.

Guatemala also has a diverse potato production base supported by local research and seed development programmes. The Instituto de Ciencia y Tecnología Agrícolas (ICTA) has developed and documented improved varieties and technologies for potato production, including work on certified seed and agronomic management. Traditional and improved production systems coexist, while farmers continue to face challenges such as limited access to quality seed, fragmented supply chains, pests and diseases and variable productivity. Despite these constraints, the highlands remain highly suitable for potato cultivation and the crop continues to be an important component of Guatemala’s food and agricultural economy.

The history of the potato in Guatemala is connected to the wider history of potato cultivation in the Americas. The cultivated potato originated in the Andes of South America, but Guatemala is described in agricultural literature as a secondary centre of origin and diversity. Spanish expansion helped introduce and spread potato cultivation beyond the Americas, while the crop subsequently became established in Guatemala’s highland farming systems. Historical records cited by Guatemala’s agricultural research institute indicate potato cultivation in areas of present-day Quetzaltenango as early as the 18^th century, including references to Santa Catalina Sixa and Santa María Uslatam around 1771.

Over time, potatoes became an important food and commercial crop in Guatemala’s highlands. Their suitability to cool mountainous environments allowed production to expand among smallholder communities, particularly in the western part of the country. By the modern period, potato production had developed into an important source of income as well as a staple food, with improved varieties, certified seed programmes and agronomic research supporting commercial production. Today, Guatemala remains one of Central America’s important potato-producing countries, with production concentrated in the highlands where altitude and climate provide favourable growing conditions.
