Social Science Section


Realizing the importance of islands agriculture to provide better livelihood support with integrated approach for the people of these remote islands, CIARI has been entrusted with the objectives of making these islands self sufficient in food production and providing the decent livelihood to the population in general and youth in particular. With the change in macro-economic conditions and requirements of agricultural commodities, the paradigm of agricultural production has changed. The aspirations of farm youth have also heightened due to enhanced connectivity and more exposure to outer world. Keeping the challenges ahead, the Institute has identified the thrust areas to work upon and Social Science section has been given one of the important themes “Transfer of Technology and Socio-economic impact analysis”.

From the very beginning, the section has been playing important role of bridge between various divisions of CIARI and the farmers of the islands. Before taking up any technological interventions, the study of social profile of clients/ stakeholders is very much essential so as to make the technology economically feasible and socially acceptable. Socio economic variables also play an important role in further adoption of the technology and its expansion. The job is primarily entrusted to the Social Science section. For its further refinement, the feedback from field trials is also collected and synthesised by the section and given to biological scientists. Finally the technology is assessed and necessary inputs for refinement are collected, synthesised and given back to biological scientists. Technology development is not the end of job for the researcher until it spread vertically and horizontally among the stakeholders. Therefore social scientists come in to the picture by carrying out its impact assessment.

Since the establishment of the institute in the year 1978 all the ToT programmes were mandated through only one section i.e., Agriculture Economics, Extension and Sociology (AEES) which, later on was christened finally to Social Science. Over the years, the efforts in the direction of imparting need based trainings and other capacity building programme through the social science section have been extended through collaborative approach. Through its efforts, CIARI have laid landmarks in livelihood improvement of Tsunami affected small and marginal farmers.

For the effective implementation of the ToT programms in the field adopting group approach this section has been instrumental in running full fledged programs viz. Village adoption program, IVLP, TARP in South Andaman District and for the last two years a ToT program dedicated for North and Middle Andaman District is running in the name of Out Reach Centre supported by NABARD. Over here 1200 farmers have been trained in agriculture and allied fields, a total of 173 demonstrations covering 37.36 ha and Seed Village Concept of Rice was introduced in participatory mode. Dhal Mill, Vermicompost unit, Piggery, Goatry, Duckery, Fresh water Fish seed production , Earthworm production are selected interventions for livelihood support of the stakeholders.

For the holistic implementation of the agricultural and rural development programmes, this section has functional links with the State Development Departments like Agriculture, Animal Husbandry and Veterinary Services, Fisheries, Rural Development, Health services, Social Welfare Advisory Board, Nationalized Banks, NABARD, PRIs and the NGO’s

Thrust area

  • Socio economic analysis and policy issues
  • Impact studies on the technologies developed and their adoption.
  • Studies on agricultural marketing and development linkages.
  • Technology assessment, refinement and dissemination.
  • Capacity building of the stakeholders in agriculture and allied fields through customized and vocational trainings
  • Consultancy in agriculture and allied fields
  • Advisory services, ATIC, KCC activities and coordination in Institute programmes.


  • Agricultural Technology Information Centre (ATIC): ATIC has been established at this Institute as a “Single Window” system to deliver the technological inputs, products and services directly to the farmers and other end users to reduce the dissemination loss in “technology transfer” on 11th October 2000.
  • Choupal: On campus training, scientists –farmer’s interactions, farmer’s meet/Gosthi, film shows are conducted regularly to transfer knowledge and skill on the latest technologies in agriculture and allied field to the island farmers and other stakeholders.
  • Art & Photography unit: A separate unit for developing and demonstrating attractive miniature models, posters etc., of technological interventions in agriculture and allied field for the benefit of the farming communities
  • Exhibition Hall/ Museum: Glimpses of Research, development and extension activities undertaken by various divisions of the institute and KVK are depicted in the Dweep Krishi Darpan hall for giving first hand information to the visiting dignitaries of main land and islands.
  • Kisan Call Centre: Toll free number 251444 is provided to facilitate the farmers of these islands to enquire about the various problems faced during the crop period and to know about the technologies in agriculture and allied fields. The query is referred to the concerned scientist and after getting the opinion of the scientist it gets transmitted back for necessary action at their end.
  • Repository of Video Films: Twenty video films on different technologies are being maintained at given point of time and shown to the farmers in regular manner during training and interactions sessions.
  • Out Reach Centre at Diglipur : With training facilities for a batch of 40 participants at a time.

Project-wise Achievements

Natural resources degradation and socio economic impact of leased farming in Andaman:
  • Minimum rate of soil erosion observed in forest sites. Nutrient levels were greatly enhanced under forest canopies. Sediment had also lower organic matter content, nutrient concentration and pH values. More clay was eroded on steeper slopes. Selective clay depletion will have serious implications on soil structure and fertility. A comprehensive research by a multi-disciplinary team is needed for building good data base and identifying the conservation measures for vulnerable lands.
Impact Assessment of Technological Interventions in Andaman :
  • The study revealed that the maximum return per rupees investment was in case of Nicobari Fowl (Rs.7.77), followed by Perking Duck (Rs. 7.33), Induced fish breeding (Rs.6.0), Composite fish culture (Rs.3.67), Yorkshire pigs (Rs.3.25), Broad bed furrow (Rs.2.9) and Earthworm production (Rs.2.46)
  • The major benefits of interventions estimates were enhancement in family income and employment generation. Some important constraints were lack of labour, marketing, storage facilities and non availability of essential input in time.
Demand and Supply Analysis of Livestock Products in Andaman:
  • The study undertaken in South Andaman showed that prices of mutton and chicken rise during dry season where as that of pork falls. The milk consumption was less than the requirement where as meat consumption was higher. The expenditure pattern indicated that out of total monthly budget of Rs 10464/- , 47% expenditure went to livestock and hi-value products.
  • The demand analysis model shows that Milk, mutton and chicken were income elastic. The demand and supply estimation and projections shows that in case of milk, the present demand will increase @ 20% (appx) decadal growth rate where as supply will increase by 15% per decade. Same trend was observed in case of mutton, fish and pork.
  • The demand of chicken would be almost double in 2021 and will four times in 2031. The supply will increase faster and will surpass the demand in 2021.
Determination of carrying capacity of islands and its potential for organic farming:
  • The estimates of production and requirements of various food commodities indicated that these islands are deficient with respect to almost all the major commodities ranging from 23% (milk) to 100% (sugar).
  • Analysis was done to assess the scope of organic farming in the islands. Several available options were explored. And it was found that if BGA/ Azolla is applied in at least 50% of rice fields and composting of all the available residue/execrate is taken up along with that, we would be in a position to meet 51.67% requirements of N, 17.62% of P and 17.98% of K.
Out Reach Centre, Diglipur:
  • In order to popularise the improved technologies and bridge the technical gap in North Andaman, a participatory initiative (Out Reach Centre) has been undertaken which was established with the support of NABARD. Training programmes and technological demonstrations are being carried out regularly by the centre. Seed Village concept was introduced for the first time in the year 2011 and 3 tons of truthfully labelled seeds has been produced in an area of 0.95 ha in participatory mode.
