식생과 토양의 역할을 고려한 저탄소 토지이용계획 수립방안 II

Abstract

The role of vegetation and soil in absorbing and storing carbon is important in enhancing and conserving carbon reduction capabilities in devising land-use plans. The Korean government has established the "Green Growth" goal to push ahead with the plan for developing environmentally friendly land and urban areas. Moreover, as stipulated in "Framework act on low carbon, green growth," carbon absorption sources such as vegetation and soil need to be increased in volume. Therefore, the primary objective of this study is to suggest strategies of low carbon land-use planning, taking into account the carbon reduction capabilities of vegetation and soil over a two-year span (2009~2010). In the first year, policy directions were established for land use plans that consider the role of vegetation and soil, and proposals for land use plans at the regional and national level were forwarded. This year, detailed political strategies will be devised by analyzing the improvements needed when developing environmental assessment and comprehensive urban plans via case studies. Also formulated will be political strategies by each disparate space unit in the region will be arranged to efficiently establish land use-plans and proper methods for calculating the amount of carbon storage and absorption. In order to examine the changes of carbon storage, absorption, and emission in environmental assessment, four case studies were selected: housing redevelopment project, residential development project, housing construction project, and photovoltaic power plant construction project. The result shows that carbon storage and absorption decreased and carbon emission increased in case of project implementation more so than in case of no implementation, with the exception of the case of the housing redevelopment project. Therefore, the consideration for the effects of the carbon emission sources as well as absorption sources is needed in environmental assessment which takes into account only the amount of carbon emission of greenhouse gases. To achieve this requires that the amount of carbon storage and absorption in no project implementation should be kept to a minimum even after implementation. In addition, to the minimization of the destruction of carbon absorption sources and preservation of the current topography need to be considered and included in the stage of project planning and site designation. Gangneung city was selected for examining the improvement of comprehensive urban plans. The result predicts that the amount of carbon storage and absorption will decrease by the goal year compared to the basic year. Therefore, the amount of carbon storage and absorption by the goal year should be reflected in developing comprehensive urban plans. As shown above, in order to establish efficient land-use plans, a nationwide target value of carbon storage and absorption under the basic principle of maximization of carbon storage and absorption needs to be set, and then the establishment of the detailed land-use plans to achieve an allocated amount of political target value by space units at the municipal and local level. Moreover, carbon credit awarded by additory carbon can be provided as incentives or used as market mechanisms. This study has developed reliable methods for calculating the amount of carbon storage and absorption to efficiently implement such plans, with the consideration for building an organizational system for managing carbon absorption sources.
