Comparative analysis on economic return including carbon storage value from Rhizophora Apiculata plantations for conservation and commercial purposes in Pattani province
Abstract:
The objective of this research was to carry out the comparative analysis on economic return from Rhizophora apiculata (R.apiculata) plantations for conservation and commercial purposes. The R.apiculata plantation for conservation purposes provided benefits only from carbon storage value but R.apiculata plantation for commercial purposes provided benefit from 3 patterns of wood use: 100% charcoal production, 99% charcoal production plus 1% construction materials, and 100%construction materials, including carbon storage value. The result of this research showed that the R.apiculata plantation for conservation purposes had a net economic return of less than for commercial purposes. The R.apiculata plantation for conservation purposes had the minimum and maximum present value of net economic return in the30th year at 33,030 to 6,905 bath/ha. and -28,917 to 29,581 baht/ha. respectively. The benefit came mainly from the carbon storage value. For commercial purpose, benefit depended on patterns of wood use and carbon storage value. The present value of net economic return in the 30thyearvaried according to the pattern of wood use: 100% charcoal production, between 96,864 and186,256 bath/ha., 99% charcoal production and 1% constructionmaterial, the minimum was135,878 to 262,943 bath/ha. and the maximum was 153,046 to 296,689 baht/ha.; and 100%construction material, the minimum was 900,321 to 1,765,511 bath/ha. and the maximum was1,358,105 to 2,665,357 baht/ha.. The R.apiculata plantation for commercial purposes (100% construction material) had the highest carbon storage at 138.78 tc./ha.. The carbon storage value of R.apiculata plantation for conservation purposes was 104.78 tc./ha., and R.apiculata plantation for commercial purposes (99%charcoal production and 1% construction material) was 1.23 tc./ha.. R.apiculata plantation for commercial purposes (100% charcoal production) had no carbon storage. In conclusion, if Thailand would like to participate in solving the climate change problem by mangrove management, R.apiculata plantation may be considered because it gives a considerable economic return.
