Ammomum
plantations inside rain forests
Ammomum villosum is a ginger species which is frequently used in Chinese medicine. The species grows best under shade and in the micro climate of a rain forest Xishuangbanna's hill tribes are producing Ammomum sometimes in large scale inside the forests. It is argued that this is a destructive form of agriculture as it does not allow undisturbed re-growth of forest tree seedlings and other species of the under story. However, in our view, it is still much better than the farming systems which require destruction of the forest altogether - and which are practically all others! Consequently, we should thank the Akha, Aini, Hani, and many other ethnic minorities for keeping the ecosystems functions of a rain forest intact by this unique farming system. ![]() Ammomum is the plant on the ground. It grows to about 2 meter. The market products are the fruits or dried seed capsules.

Your
ecologically friendly crop production: Agriculture in Yunnan is largely designed by ethnic minority people from more than 20 distinctly different ethnic communities. Wherever possible, and mainly in the fertile lowlands, rice fields are forming the landscape. In the mountains, shifting cultivation is predominant, although it is now gradually given up and replaced by more permanent forms of agriculture. Of course, also agricultural industry has taken its toll and large mountain areas are under sever environmental stress by destructive ways of growing crops like sugar cane, corn, rubber, pine apple, and even the famous Puer tea. This page depicts some of the unique land-use forms of Yunnan.
