II. Utilization of results of the completed and Ongoing Research Projects in the Department of Basic and Social Sciences
- M.Sc thesis research on impact assessment – Ongoing
- Research project on Prediction and validation of growth and development of Melia dubia using nonlinear multilevel mixed effects model is in progress. Under which the yield is being predicted under different soil types and climate conditions. Based on the yield prediction, the Yield Gap I (Difference between the research station yield and the progressive famer’s yield – the Maximum) and Yield Gap II (Difference between the progressive farmer’s yield and average farmers’ yield) will be estimated to understand the technological, endowment and management gaps in order to suggest to the FC&RI for technology precision and conduct of outreach for management efficiency among the farmers for higher productivity.
- Research project on Construction of Growth and Yield Prediction Models for Neolamarckia cadamba in Western Zone of Tamil Nadu is in progress. The study brought out the spread of this species including the yield obtained by both the farmers and with precision silviculture. With adoption of precision silviculture, yield prediction was found superior over the farmers. Duration of economic felling is lesser with precision silviculture as compared to famers’ practices. Based on these results factors such as technological, endowment and management influencing Yield Gap I (Difference between the research station yield and the progressive famer’s yield – the Maximum) and Yield Gap II (Difference between the progressive farmer’s yield and average farmers’ yield) will be determined to assess the impact of precision silviculture.
- Research project on An Economic Analysis of Melia dubia across multiple use benefits in Western Tamil Nadu is in progress. Under this project the opportunity cost of cultivating Melia dubia and technologies adopted by the famers are being gathered. Based on the outcome of the project, number of industries having contractual arrangements with farmers will be contacted to assess the costs and benefits of both industries and farmers. Further, the technological adoption gaps with regard to precision silviculture will also be assessed to understand the technological rate of adoption and impact.
- Research projects on Identification and conservation of forest genetic resources used by the tribal community are under progress. As one of the mandates of FC&RI is to identify the genetic resources with special features, the outcome of the project will helpful to identify the forest genetic resources which are likely to be extinct and have special features.
- Financial Requirement:
- The financial cost for undertaking the impact assessment will be submitted to meet the expenses of the project.
