Abstract
The basic component of any country’s knowledge system is its Indigenous Technical Knowledge (ITK). It is a cumulative body of knowledge and techniques handed down through generations by cultural transmission of the relationship of living beings including humans with one another and their environment. ITK practices in agriculture are farmer-friendly, socially-accepted, economically-feasible and environmentally-sound and suited to the specific bio-physical and socio-economic conditions. This knowledge has tremendous potential to address the current concerns of conventional agriculture like depletion and degradation of the natural resource base, poor productivity and pest and disease problems. Assessment of ITKs for their scientific rationality could be a step towards their integration in the formal research system for knowledge management for sustainable agricultural development. Keeping this in view a study entitled, "Scientisation of Indigenous Technical Knowledge of Tribal Farmers in Ranchi district of Jharkhand" was undertaken with the objectives: i. To identify the process of systematic documentation and scientisation of Indigenous Technical Knowledge, ii. To study the process of scientisation of Indigenous Technical Knowledge about pest and disease management among tribal farmers, iii. To delineate the constraints encountered in utilisation of Indigenous Technical Knowledge by tribal farmers and 4. To develop a framework for systematic documentation and scientisation of Indigenous Technical Knowledge. Ranchi district of Jharkhand was selected purposively keeping in view substantial tribal population in the district. Two blocks namely, Angara and Tamar were selected purposively, being the tribal dominated blocks in the district. From each selected block two villages namely, Dhurleta and Jaspur from Angara and Amhesa and Uludih from Tamar were selected randomly from among the tribal dominated villages. Selection of tribal farmers was done through snowball sampling. Descriptive research design was used for this study. Three categories of respondents i.e. 55 ITK experts spread across the country, 30 plant protection scientists belonging to State Agricultural University and ICAR system located at Ranchi and 45 tribal farmers who acted as key informants from selected villages constituted the sample for the study. ITK experts and plant protection scientists were randomly selected from the list and multistage sampling procedure was followed for selection of tribal farmers. Delphi technique was employed to identify ideal steps in the processes of systematic documentation and scientisation of ITKs by the experts. Scientisation process was conceptualised in three sequential steps of particularisation, validation and generalisation. For particularisation, rationality analysis of selected ITKs was done by the plant protection scientists. For this, three types of rating scales were used. Validation was done through Quantification of Indigenous Knowledge (QuIK) method by the tribal key informants and Mean Perceived Effectiveness Methodology (MPEM) by the scientists. For generalisation, scientists were asked to indicate whether ITKs can be disseminated directly or require certain modifications/ blending with corresponding scientific technologies (CSTs). For better utilisation of selected ITKs the tribal farmers were asked to indicate their preferences of mode of dissemination. For the constraints encountered in utilisation of ITKs, tribal farmers were asked to indicate degree of importance of constraints on a 3-point continuum. Based on the findings of the referred aspects, a process framework was developed for systematic documentation and scientisation of ITKs. The findings led to conclude that majority of the tribal farmers were females of old age belonging to Oraon communityhaving education up to middle school level and marginal size of holdings with long farming experience, lower level of risk orientation, social participation and innovativeness and majority of the ITK experts were males of age group of 51-65 years, holding senior positions in SAUs and ICAR institutes with experience between 10-15 years involved in extension and ITKrelated work to a greater extent. The ITK experts suggested that a combination of suitable methods should be used for documentation of ITKs. The most preferred scale to assess the scientific rationality of ITKs was reported to be 3-point scale of Dhaliwal and Singh (2010) followed by 5- point scale of Hiranand (1979). QuIK was found to be more preferred method for validation followed by MPEM. For generalisation of ITKs, a consensus emerged that if ITKs are at par with their CSTs in efficacy and effectiveness may be disseminated directly to the farmers as well as through their Ready to Use (RTU) products. Otherwise, further experimentation should be done by blending of both the knowledge systems. ITKs which were considered for QuIK analysis i.e. control of Rice hispa (Parsu leaves or Mahua leaves are applied), Rice caseworm (Solution of tender bamboo shoot extract with water or Parsu leaves). Bihar hairy caterpillar (Mixture of Ash and Kerosene oil or Sinduwar leaves + Sand + Kerosene oil), Rice gall fly (Parsu leaves or Sinduwar leaves) and Banki disease (Bamboo rhizome pieces mixed with water or leaves of Neem) were found to be superior to their CSTs in terms of cost-effectiveness, environment-friendliness and farming system compatibility whereas CSTs were preferred more in terms of effectiveness in controlling pests/diseases, quickness in problem solving and ease in preparation. Farmer to farmer extension was suggested by the tribal farmers for generalisation of ITKs followed by maintenance of ITK register and creating awareness through different extension methods including publication of extension literature and use of information communication technology. In order to increase the accessibility of ITKs, a process framework has been developed with the main partners of research, extension and user systems to facilitate sustainable agricultural development.
