Thailand Voluntary Emission Reduction Program (T-Ver): A Case Study of Estimation Carbon Stock Using NDVI in Dry Dipterocarp Forest in University of Phayao
Abstract:
Currently, global climate change and temperature are intensified. These are partly due to deforestation, and forest degradation was causing carbon dioxide emissions into the atmosphere. Therefore, forest conservation and reforestation will be an alternative way to reduce greenhouse gas emissions to absorb and store carbon stock in the earth's ecosystem. Forest ecosystems play an important role in reducing atmospheric carbon dioxide through photosynthesis and stored in tree biomass. The objective of this study was to estimate aboveground and belowground carbon stock in Dry dipterocarp forest, University of Phayao, and to prepare carbon credit for the voluntary greenhouse gas reduction emission mechanism according to Thai standards. The results show that total carbon stock was 11.97 tC/rai (43.90 tCO2eq) and divided into aboveground and belowground (roots) carbon sequestration were 9.43 (34.56 tCO2eq) and 2.55 tC/rai (9.33 tCO2eq), respectively (Data from May 2018 to June 2019). In addition, the expected amount of greenhouse gas reduction is 723 tCO2eq/year, and equivalent to carbon credit markets in the Verified carbon standard (VCS), European Union emissions trading system (EU ETS) and Thailand voluntary reduction emission (T-VER) program was approximately 95,110.54, 401,120.13 and 24,842.94 THB/year respectively. In Thailand, carbon trading depends on negotiation prices under Thailand's voluntary carbon market agreements. However, this study has not assessed carbon sequestration in sapling and soil organic carbon. Therefore, data collection methods should be optimized and studied in the long term to understand the mechanisms of carbon sequestration in forest systems. As well as creating positive incentives to conserve forest resources. Increase revenue from natural carbon sequestration and provide an alternative to building a grassroots economy for further sustainability.
