摘要

Agro-biodiversity, or agricultural biodiversity, includes all the components of biological diversity of relevance to food and agriculture, as well as the components of biological diversity that constitute the agro-ecosystem: the variety and variability of animals, plants and micro organisms, at the genetic, species and ecosystem levels, which sustain the functions, structure and processes of the agro-ecosystem. Indigenous and traditional agricultural communities throughout the world depend on, and are custodians of, agro-biodiversity maintained within agricultural landscapes through various forms of traditional resource management.Homegarden-a component of agro-biodiversity is an important source of food security and livelihoods as it supplies diversified vegetables and fruits rich in micronutrients, provides spices and herbs to meet culinary and cultural requirements, provides medicines for relief, ecosystem services and income. Despites its small area, a homegarden is a biodiversity rich production system and should be considered as a viable unit of on farm biodiversity conservation. Moreover, it is an important contribution tosustainable agricultural production, because of their potential to meet several economic, social, ecological and institutional conditions for sustainability. The aim of the present study is to document the cultivated plant species in the homestead and also investigate the plant diversity according to different ethnic community.
