Early evaluation of the verification tools for Taiwan's carbon sink

Absrtact
This project consists of five goals, with the results summarized in the following: 1. In terms of the “the Relevant Regulations and Investigation Status of Carbon Sink and Inventory Check of Domestic Land Use”, the definitions of International Greenhouse Gas Policies and Agreements, IPCC Guidelines for National Greenhouse Gas Inventories, Development of National Greenhouse Gas Emissions Inventories, and the Six Types of Land are firstly discussed in this chapter, followed by the checking of our country’s current strategy of land use, and the development and status quo of domestic land use investigation of the various units. Later in this chapter, the relevant theories and methods of surveying the ground sample and flux tower, as well as the related data of the carbon sink in the six types of lands in our country are listed. 2. In regard to “Analysis of Land Use Change in Taiwan with Satellite Telemetry Data”, the MODIS satellite and the telemetry principle are introduced, and then the results – the telemetric results of the six types of land uses in Taiwan and the human interpreted results of traditional aerospace photographs – are compared to verify the correctness rate of the interpretations. In analyzing the telemetric results of the land use in Taiwan, the area changes and the distribution of the six types of land in Taiwan during Year 2000 – 2013 are obtained and presented in Taiwan’s land use change matrix. 3. In terms of the “Estimation of Carbon Sinks For Taiwan's Forests and Other Land Uses with Dynamic Vegetation Pattern”, the basic principles and the model features of Dynamic Global Vegetation Model (DGVM) are introduced. Three DGCMs are used to stimulate the total amount of carbon sink changes per year during 2000-2012 in Taiwan, to draw the contribution map of carbon flux, and to compare and analyze with the fourth national forest resource survey results. 4. Regarding “Integration of Dynamic Vegetation Patterns and Ground-area Survey and Flux Tower to Establish the Carbon Sink Verification Tool in Taiwan”, the differences of sample area survey, computer model and flux tower in the principle of carbon sink survey are analyzed. Recommendations of Taiwan’s carbon sink verification tool are proposed after discussing and consolidating different approaches for the estimation of carbon sink data and their limitations. 5. In terms of the “Research on Taiwan's Participation in International Carbon Right Trading and the Establishment of Forest Carbon Sequestration Methodology”, the differences and similarities of the AR-CDM system, the verified carbon standard (VCS), and the China Certified Emission Reduction are analyzed in the beginning of this chapter, and followed by summarizing the key factors, proposing viable approaches and procedures for establishing a self-owned forest carbon sequestration methodology in Taiwan. In addition, the analysis of the most appropriate countries with diplomatic relations with us for Taiwan to participate the international REDD+ program has also been completed.
