Abstract: The Lisus, also known as Yobin are the dominant tribe in the South eastern periphery of Namdapha national park in Changlang district of Arunachal Pradesh. They spend most of their time in the forests where they practice jhum cultivation and hunt wild animals. The hilly terrain and inaccessibility have forced them to innovate things to save time and energy. Through time, the Lisu people have earned good knowledge of agricultural as well horticultural crop production. They also know the technique of grafting horticultural plants. Using this knowledge they get fruits they wish to grow in a short duration of time, eg.Diospyros kaki (Thaj), a fruit tree commonly grown by the Lisus. Fruiting is made only when it is grafted with a specific wild plant (Slani in Lisu), which is abundant in the jhum fallows. Different horticultural fruits like Diospyros kaki Linn. f. (Thaj), Citrus reticulata Blanco, (orange), Ananas comosus (L.) Merr., (pineapple), Psidium guajava Linn. (Guava) etc. are also cultivated permanently in the abandoned jhum lands for rehabilitation of fallow agricultural lands, which is generally not observed among other tribes of Arunachal Pradesh. The Lisu tribe has rich traditional as well as technical knowledge due to the numerous hardships they face, which have compelled them to innovate things and make new gadgets. Most of the households at Vijaynagar and Gandhigram have the flowing-water operated gadget used for milling rice without applying manpower. Due to difficult terrains, consisting of mountains and rivers they have built hanging bridges completely made of wood, bamboos and canes to connect village to village and to the agricultural fields. Thus, the indigenous knowledge systems and traditional technologies help in natural resource utilization among the indigenous (Lisu) tribe. However, such eco-friendly technologies that are energy efficient should be promoted for conservation and further replications elsewhere.
