In the fragile island environment in which the agricultural development has to take place, it is particularly important that it addresses the environmental concern and inculcate stability to the tribal system. It should also take into account the tribal customs and availability of resources. In the last few years increased interaction with the local people, capacity building, characterization of the resources of these islands at larger scale and research efforts to understand and enhance the farm production in the tropical island of Nicobar have helped to generate lot of information pertaining to the tribal farming. We have also engaged in implementation of several programmes aimed at diversification of tribal farming system. This experience is translated into information and documented. These are very vital information required by several stakeholders for successful implementation of any developmental plan.
