摘要

Te objectives of this research were to 1) study changes in land use of Agriculture, Forestry and OtherLand Use (AFOLU) sector using GIS application as a tool for accounting land use type area for eachgiven periods, 2) to estimate the amount of carbon stocks, and carbon dioxide emissions and removalsfrom changes of 6 land use types (mangrove forest, cropland, grassland, wetlands, settlements, andaquaculture land) which were evaluated under the standard method of the 2006 IPCC Guideline forNational Greenhouse Gas Inventories, and 3) to evaluate the economic value of carbon dioxide basedon existing carbon price in California Carbon Market. Te result showed that between 2001 and 2015in Yi San Sub-district, Samut Songkhram Province, di?erent types of land use were changed fromaquaculture to mangrove forest (974.37 ha), followed by mangrove forest to aquaculture (770.75 ha),respectively. Mangrove forests increased in carbon stocks due to biomass growth of 50,730.63 tC andthe large proportions of decrease in carbon stocks in biomass were from aquaculture land as -21,735.14tC. Te estimation of total carbon dioxide emissions was +123,043.83 tCO2 and total carbon dioxideremovals were -190,409.73 tCO2. Te land use with the highest carbon dioxide emission was theaquaculture land (+81,696.64 tCO2), followed by the grassland (+35,058.26 tCO2) and settlements(+5,509.30 tCO2), respectively. Te land use with the highest amount of carbon dioxide removal wasthe mangrove forest (-186,012.28 tCO2), followed by the cropland (-2,257.41 tCO2) and grassland(-2,140.04 tCO2), respectively. Te highest gain of economic value from CO2 removals was the mangroveforest (2,808,785.43 USD) followed by cropland (22,314.48 USD). Te highest economic loss from CO2emissions was the aquaculture land (1,233,619.26 USD) followed by the grassland (497,065.12 USD)and settlements (83,190.43 USD), respectively. As a result, those land use changes can reduce globalwarming potential (GWP) up to -67,365.90 tCO2e and increase the net total carbon economic valueas 1,017,225.09 USD.
