摘要

The global energy crisis is profoundly affecting the developing countries, which contain three quarters of the world population. Experiences of Asian countries show that biomass energy plantation projects are not appropriate for achieving the social objective of poverty alleviation. Sri Lanka is gaining popularity in organic tea production as a health beverage. The environmental and economic benefits of using Dendro-thermal energy in organic tea production have not been investigated in Sri Lanka. This study was designed to assess the economic and environmental sustainability of dendro-thermal energy for curing of tea in organic tea production. The data was collected from an organic tea producing factory and 33 randomly selected fuel wood suppliers in the Badulla District in 2008. Extended benefit cost analysis was carried out to evaluate the economic and enyironmental sustainability of dendro-energy use in drying tea Benefit transfer method was employed to value the environmental sustainability such as reforestation, biodiversity, soil erosion and soil fertility.The study revealed that the annual economical gain of using dendro-power for tea dry was Rs. 7,548,000 with other social and environmental benefits. The economic analysis results showed that the dendro-thermal had an overall beriefit. Sensitivity analysis suggests that no uncertainties exist in transferring fossil fuel to dendro-thermal energy use in organic tea curing. Most farmers who supply bio mass had positive perception on continuedsupply. Since land size of each farm is Hmited, organizing contract farming with large groups is important to meet the fuel wood demand. These results also show that there is a good level of increase in soil conservation and soil fertility by conservingbio diversity with the dendro-thermal fuel wood supply, immediate economic benefits and the protection of soil and water can go hand in hand especially when enhanced by collective action.
