Potato as a food security crop 馬鈴薯為糧食保障農作物
This map shows the global distribution of potato production (in tonnes). The biggest potato producer in the world during 2007 is China, followed by Russia and India.
Potato has a long history in human society and it grows almost anywhere. It has probably originated in the Andes in South America. Most of the wild and cultivated species are from Peru.
The major species grown worldwide is Solanum tuberosum. Potato is rich in starch and is one of the most important food crops. It also contains multiple minerals and vitamins.
Potato can also grow in relatively harsh condition compared to other major crops. It is therefore ideal for developing countries, where land and resources are limited. It is recommended as food security crop that can help low-income farmers and consumers.
