International Potato Center (CIP)

The International Potato Center (CIP), based in Lima, Peru, conducts research for development on roots and tubers  to make them adaptable to different climates, regions, and users’ needs. We apply research results to projects that focus on increasing food security, improving productivity and incomes, and enhancing sustainable development for small farmers and impoverished populations in Africa, Asia, and Latin America. CIP’s genebank safeguards the genetic biodiversity of over 80% of the world’s native potato and sweetpotato cultivars.

CIP has regional offices and project activities in some 30 locations across Sub-Saharan Africa, Asia, and Latin America. We receive funding from over 55 international donors. Our work is expanding the potential value of these crops for improving nutrition, gender equity, and livelihoods and for narrowing the yield gap. By integrating potatoes and sweetpotatoes into multiple systems—production systems, marketing systems, and value chains within different countries—CIP is helping to secure the untapped potential of these crops to continue to play a pivotal role in food security and poverty alleviation.

Guía para la construcción y el mantenimiento de un túnel de red para proteger la calidad del material de siembra del camote de los virus transportados por insectos

Esta guía presenta los pasos a seguir para la construcción de un práctico túnel cubierto con red para uso agrícola y las instrucciones sobre como manejar los cultivos de camote dentro del túnel para asegurar la provisión de material base de siembra de alta calidad, con baja o nula infección por virus, como multiplicadores de material de siembra para ser renovados continuamente en campos de camotes. Esto permitirá a los agricultores mantener las productividad de la producción de camotes a través de los años. En Kenia, el beneficio neto promedio fue de $720 por túnel en los 3 años.

A guide to construct and maintain net tunnels to protect quality sweetpotato planting material from viruses carried by insects

This guide provides the steps for constructing a practical net covered tunnel at the farm level and instructions on how to manage the material in the tunnel to ensure a supply of high quality foundation planting material, with little or no virus infection, for farmer planting material multipliers to use to continually renew the planting material in their sweetpotato fields. This will enable farmers to maintain their sweetpotato yields over time. In Kenya, the average net benefit was $720 per tunnel over 3 years.
