Important Announcements:


Market and export potential analysis of marine fishery resources in Andaman and Nicobar islands

  • In A & N Islands about 97 number of  fisherman villages and 3274 families driving livelihood from fishing profession with more than 15000 population. These fishermen mostly migrated from nearby states.

  • Total potential of fisheries in A & N Island is about 1.48 lahk tones but due to lack of infrastructure and equipments only less than 20 percent is being harvested.

  • The income structure of fisherman indicated that most of them are low income people.

  • They drive about 70% income from fishery sector and 30 % from labour, carpenter, net knitting and other sources.

  • Consumer fish price indicated that it has been increased about 63 % from 2008 to 2011.

  • Market cost incurred by the different intermediaries mostly on transport, Ice, labour expenses etc.

An economic analysis of floriculture and vegetables potential in andaman and nicobar islands

  • Prices of flowers and vegetable are having very unpredictable behaviour.
  • Islands are producing most of vegetables in sufficient quantity in February to April only rest of the period it is being imported from mainland.
  • Market infrastructure including transportation and cold storage facilities are poorly developed.

  • High price differences in different sites of productions and consumption.

  • Poor database on market information about flowers and vegetables.

  • The total flower sellers in these islands were 32 no. Shops.

  • Total area required to meet the local demand is about 7.0 ha. Under protected cultivation.

  • Huge money can be saved for local flower cultivators by producing flowers locally.

  • The impact of the recommendation of project is that more area has been put up by the agriculture department A & N Administration under protected vegetable and flower cultivations.

Economic valuation of mangroves in andaman and nicobar islands

  • Total economic value of the A & N Mangroves was worked out to be more than 12000 crore/ Annum on current price.

  • Per households harvest more than Rs. 65000/- worth benefits annually from the mangroves. Per ha. Economic value of mangroves was found to be more than 2.0 lakh/ha./ annum.

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 had 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.

Identifying Livelihood Options and Training Needs Compatible to Self Help Groups to Fructify these Options

  • The status of credit linkages of the Self Help Groups  in these islands was studied which reflects that a total of 702 groups have been credit linked of which 481 are in South Andaman comprising of 435 as women, 17 men and 29 mixed groups.  In North & Middle Andaman district out of 213 groups, 175 are women followed by 20 men and 18 mixed groups and in Nicobar district only 8 groups which are women only have been linked.  The overall credit linkage of the Self Help groups accounts for only 31.60%. 

  • The strength of the group was found to be 10.48 with the average corpus money of 1.26 lakhs per group which was found to be optimum to start any agriculture & allied enterprise as livelihood venture. 

  • The findings on the   expenditure pattern on saving together accounted for 71 percent on social capital i.e. health, education and household.

Impact Assessment of Technological Interventions in Andaman

  • Over the period from 2000-2011 the Institute, has been successful in transferring 136 technologies in agriculture and allied fields for the benefit of the stakeholders of the A & N islands.  The contribution towards the technology transfer comprises i.e. 31(23%) by division of Animal Science, 29 (21%) by Horticulture & Forestry, 24 (18%) by Natural Resource Management, 23 (18%) by Field Crop Improvement and Protection, 22 (16%) by Social Science and 7 (5%) by Fisheries Science Division. 

  • Out of 136 technologies   during 2000-2011 transferred by the Institute, following technologies viz   crop Based (BBF, Rice variety and IPM module),      Livestock based (Boer goat, Pig and Quail) & Fisheries based (IMC, Fresh water prawn & Crab fattening were selected. Interview schedule was constructed and data collected among the representative sample.
  • Technology on Composite fish Culture with CRM was also promising both at South & North & Middle Andaman District.  In few cases the farmers have restored the adoption of the technology even after Tsunami 2004 in South Andaman which describes about the potential of the technology at ground level.   An   average harvest return of 2.5 to 3.0 t/ha/year. Was received.Many farmers through the sale of the fish i.e. 1.5 to 2 per year could earn an income of Rs. 1.85 to 2 lakhs.  Fish & poultry has become one of the components in their family consumption. The horizontal spread of the technology was found to be to the tune of 20 ha. The farmers are getting a regular income and assured nutritional supplement the family.

  • BBFs introduced under the FRARP project were found to have been adopted by the farmers in the village clusters of South Andaman. They opined that it was a good technology which assured round   the year return from the field, mitigated the risk factor and also gave an additional income.  There was an additional income of Rs 20 to 25000/ and employment generation of 90 to 120 mandays. The problem was of pest & disease attack as there on the crop grown because the neighbouring farmers have not restored to farming completely was seen. Extension of the area   due to joint mutation of the land was not possible.The upscaling of the technology has been done as the Lead Bank has sanctioned to finance the technology through KCC.The Administration has come forward to popularise the technolog through RKVY Scheme.

  • The detailed study with more samples of the technologies in South, Middle & North Andaman is in progress to give a feedback on Socio economic impact (before & after), technology gap, technology index, technology spread & constraints in adoption.

Database development

  • Developed ANN model for forecasting of rice yield for the island

  • Database on AGRANI have been developed and linked with the website

Project-Potential and prospects of Campbell Bay being production hub to meet requirements of PDS (rice) and perishable foods of Nicobar district

  • The detail of arable land was worked out in Campbell Bay. A total 2448 acres (979.2 ha) land was allotted to 200 settlers from mainland out of this, only 61.5% was now available for cultivation.

  • As per NPR data, population of Nicobar group of islands is 39949 out of which Campbell Bay population is 8679.

  • As per ICMR guidelines, the requirement (t/yr)of various food commodities for Campbell Bay/ Nicobar group has been worked out as given: Cereals-1410/6492, Pulses- 90/413, Vegetables- 513/2362, Fats & oils- 121/555, Meat/ fish- 253/1163, Milk- 593/2730 and Roots & tubers – 432/1990.

  • The family size of respondents was 4.41. In the family, maximum numbers were young (56.24%) followed by old (26.76%). Adolescent population was only 17.23% of family size.

  • The farmers in C/B were earning a monthly income of Rs 16060 per family out of which govt service sector was contributing 39.13% followed by agriculture (29.54%) and private jobs (13.79%.

  • Among field crops, rice, maize and jowar were occupying an average area of 2.73 acres per farm. Plantation crops were being raised in 3.94 acres per farm. The operational expenses were Rs 2520/acres in case of field crops of rice, maize and jawar, Rs 2439 in case of pulses and Rs 8390 in case of vegetabes.
  • Livestock economy of in C/B  was not very strong. On an average, livestock worth Rs 15842 were kept by the farming families. Piggery were not so preferred vocation in C/B. Milk production was found to be economical and feasible.

  • The most effective source of agriculture technology information was found to be radio (freq. = 0.49) followed by TV, NGOs and Govt department.

  • To assess the timely availability and quality of inputs, farmers were asked to give score between 0-10 ranges. Except machinery and manures all other inputs were not available in time. Their score was below 5.0/10. Same was the case with their quality.

  • On an average, the expenditure on food per farm family in a month was Rs 3961. Maximum exp. was on milk and milk products followed by vegetables, non-veg foods, pulses, fruits and rice and wheat.

  • Given the average productivity, the potential harvest would be 1911 tons of rice, 108 tons of pulses and 1072 tons of vegetables per annum from 603 ha land assuming 50:50 ratio in field and plantation crops.

Demand and Supply Analysis of Livestock Products in Andamans

  • During the 1st year of investigation, socio-economic status of the farmers of South Andaman was assessed.

  • Primary data collected from livestock farmers showed that they were earning an income of Rs. 16674/ per month per family out of which max. Contribution was from service sector (52.98% followed by private jbs (30.49%. Agriculture share was only 5.35%.

  • The value of livestock kept by the families was Rs 23073 out of which about 50% was from desi cattle.

  • Price behaviour of livestock products showed that there was no difference between prices in dry season or wet season except chickens and pork. The prices of meat and chicken were rising faster than milk and its products.

  • Production was more in dry season n case of milk and eggs. So was the case for consumption as well.

  • Total consumption expenditure per family was Rs 5001/ out of which nearly 50% goes for high value foods followed by vegetables. Non-food expenditure was s 2890/ per family per month.

Determination of carrying capacity of islands and its potential for organic farming

  • The population of the Andaman and Nicobar islands was projected in different age groups over time for 1931 and based on that, given the ICMR guidelins of daily requirements in various age-groups, the requirements of various food commodities were worked out and projections were made towards 1931. Island population is mostly dependent on mainland to meet out its cereal and other food requirements.

  • Base on the production and requirements, the availability status of different commodities was worked out. As of now the islands are deficit up to 74.94% in total cereal requirements, 69.34% in pulses, 99.48% in oils, 9.62% in milk and 89.62% in meat requirements. Sugar is totally imported from mainland. Island population is dependent on mainland for its requirement of potato and temperate fruits.

  • The deficit will persist towards 1931 in almost all commodities except milk and meat, the availability of these will improve and deficit will subside beyond 1921.

    • The fruits and vegetables are in excess in dry season only but due to non availability of cold storage, their availability is difficult to maintain in rainy season. The situation can improve only at the policy levels.
