    Diversification for Livelyhood Security:Experiences from Major Coconut Growing Countries
    (2012) Kalavathi, S.; Erlene Manohar; Peyanoot Naka; Vo Van Long; Krishnakumar, V.; Thomas, R.J.; George V. Thomas; Maria Luz George
    This paper presents the success of community based organizations in achieving sustainability in marginal coconut holdings through diversification of crops and enterprises along with conservation of local varieties.The project was implemented in 19 communities of 10 coconut growing countries and findings from four major coconut growing countries, which had significant project outcome- India, Philippines, Thailand and Vietnam -are discussed in the present paper.All the four major coconut growing countries recorded a significant difference in total household income over the project period.Among the four countries,India and Philippines had a significant difference in mean income derived from intercrops,India and Thailand for livestock integration and India and Vietnam for off-farm activities. Herfindahl index for indicating economic diversity of households revealed a significant diversification of income for India as well as the overall data for the four countries. A higher level of education and more available land also positively influenced total income.In general, improvements in income were better with bigger-sized farms and households, with male household heads.The overall data revealed significant improvement in food and nutritional security with clearest impacts in India and Philippines due to project efforts. Participation of women in trainings and interventions was the highest in India, followed by Thailand.

    The nutritive values of tropical fruits like coconut are of interest to consumers and useful for the breeding program.The two experiments were carried out in Completely Randomized Design with 3 replications.The first experiment aimed to determine the essential and non-essential amino acid content of liquid and solid endosperm of potential market varieties of coconut such as young tender nut of Aromatic Green Dwarf(Nam Hom) and mature nut of hybrid Nam Hom xKathi (NHK.Among the 18 kinds of amino acids, the significant differences were found on Aspatic acid, Cystine, Serine, Isoleucine, and Phenylalanine content while highly significant differences were found on Histidine and Methionine content.The second experiment aimed to determine the fatty acid composition of virgin coconut oil of 20 coconut accessions from the coconut field gene bank of Thailand at Chumphon Horticultural Research Centre. The result showed that there were significant differences on the eight fatty acid compositions. Among the eight fatty acids, lauric acid is the most noted one by consumers and it was found that lauric acid content in virgin coconut oil (YCO) was excellent(lauric acid 48.8%) and the mean of lauric aicd content among the eight varieties had no significant difference at 5% level by DMRT. These varieties include including Renell Tall , Chumphon H ybrid No.2, Malayan Yellow Dwarf, Sawi Hybrid No.1 (MAW A), Hybrid Chumphon 60, Thai Red Dwarf, Sri Lanka Tall, and Hybrid Nam Hom x Kathi (NHK) with the lauric acid content at 51.0,50.1,49.3,49.0,49.0,49.0,48.9, and 48.8 %, respectively .These varieties, therefore, were suitable for VCO processing since they have high lauric content.
