Sustaining natural resource base and augmenting productivity of tropical systems necessitate developing comprehensive understanding on the complex crop species diversity and their potential uses in traditional agroforestry systems. The present study attempts to quantify indigenous and traditional crop species diversity and extent of usage of wild edible plants in a traditional agro forestry (TAF) system using primary data from 90 households of Konyak Naga tribe spread across six villages of a remote district, i.e., Mon, Nagaland, North-East India. Findings reveal that the TAF system is much diversified as compared to the settled cultivation system. Apart from cereals, millets and pulses, the upland tribes grow a variety of horticultural crops on shifting cultivation (SC) land. At the aggregate level, the horticultural crops in the sampled states were observed to be much diversified and the mean diversification index value was found to be 0.79 (SID) on TAF land. The present study documented 30 indigenous and traditional crops species being cultivated and used by the Konyak Naga tribe. Their food system is further complemented with wild edible plants collected from fallow land and secondary forest. The existing diversity managed with traditional wisdom in the TAF system need to be preserved and disseminated in order to ensure the sustainability of the natural resource base.

那加兰邦的传统农林业系统是否丰富了土著和传统作物物种的多样性？

维持自然资源基础和提高热带系统的生产力需要对复杂的作物物种多样性及其在传统农林业系统中的潜在用途进行全面了解。本研究尝试使用分布在偏远地区六个村庄的 Konyak Naga 部落 90 户家庭的原始数据，量化传统农业林业 (TAF) 系统中土著和传统作物物种的多样性和野生食用植物的使用范围，即，孟，那加兰邦，印度东北部。调查结果表明，与定居栽培系统相比，TAF 系统更加多样化。除了谷物、小米和豆类外，高地部落还在轮垦 (SC) 土地上种植各种园艺作物。在综合层面，观察到采样州的园艺作物非常多样化，TAF 土地上的平均多样化指数值为 0.79 (SID)。本研究记录了 Konyak Naga 部落种植和使用的 30 种土著和传统作物物种。从休耕地和次生林收集的野生食用植物进一步补充了他们的食物系统。需要保护和传播 TAF 系统中以传统智慧管理的现有多样性，以确保自然资源基础的可持续性。他们的食物系统进一步补充了从休耕地和次生林收集的野生食用植物。需要保护和传播 TAF 系统中以传统智慧管理的现有多样性，以确保自然资源基础的可持续性。他们的食物系统进一步补充了从休耕地和次生林收集的野生食用植物。需要保护和传播 TAF 系统中以传统智慧管理的现有多样性，以确保自然资源基础的可持续性。
