Agrobiodiversity in Northeast India: A Review …
133
‘landraces’ or ‘indigenous’ varieties. For the traditional homegardens the threat is
the growing importance given to cash crops such as Areca catechu leading to the
increasing dominance of such plants in the homegardens. In the case of rice farming
systems it is the increasing interest in the HYV due to absence of proper farming
techniques, land fragmentation and failure to successfully transfer the related traditional knowledge to the next generation. In view of the potential agrobiodiversity
in the northeastern region it is essential to properly document them along with the
socio-cultural practices and knowledge associated with them before they are lost to
the conversion to modern agriculture or urbanization.
