서울시 개발제한구역의 도시관리실태 평가 및 개선방향: 도시개발 현황 및 문제점

1. Background and Purpose: Since 1999, many areas in the Restricted Development Zone (RDZ) has become selected and planned as public housing areas by national government the names of housing areas are changing from National Public Housing Areas to Bogumjari Housing Areas which will be developed until 2018. The number of the areas is more than 50 at this time. Then, the development plan is made by one-by-one just only for providing housing units without thinking how wide areas can be developed. The purpose is to investigate those public housing areas into development where, when, how, and to identify problems to Seoul, and, settlements which are removed from the Restricted Development Zone are also reviewed to redeveloped properly after removal. 2. Conclusions and Policy Recommendations: Housing and population supply until 2018 will be 293% (446 thousands units) and 42.2% (1 180.9 thousands) respectively in the Restricted Development Zone over the Capital Region from 2005 to 2020. There are five regions in which public housing areas are grouped and those problems are identified: -Mostly are close to administrative boundaries, 201cm away from downtown Seoul, -Just only for housing supply so that there is not self-sufficient and is dependent on Seoul, -There in no cooperative discussion among cities and developing agencies, and each site has a development plan on its own.

Current Seoul metropolitan government`s parks and greens spaces policy is focused on the quantity of spaces; however it is crucial to prepare the plan to improve quality of parks and green spaces to address climate change and to accommodate low carbon society. Purpose of this study is to prepare the plan for ensuring feasible carbon reservoir and maximizing carbon reduction to realize the low carbon green city. 1. Function of parks and green spaces at the era of low carbon green growth Recently, the policy on parks and green spaces has shifted from ensuring quantity to improving quality of green spaces to maximize carbon reduction and reservoir in both direct and indirect ways that include the function of controlling microclimate and reducing heat island effect. The value of trees in parks and green spaces has been reevaluated. In 2009 summer, the results of measuring temperature of sites throughout the Seoul demonstrate that the green spaces and parks score the lowest and followed by the residential and commercial areas. As a result of measuring heat island effect of street trees, the eastern sycamore family (Platanus occidentalis) street at Euljilo was measured 29. 3℃ which was 8.8℃ different from the pine tree street measured 38.1℃. The Seoul Plaza, which has no trees was measured 40.2℃ and reveals heat island effect of the central city. 2, Asset analysis of green spaces The carbon storage capacity of forest is 41.4tC/ha, of urban parks is 17.3tC/ha, and of street trees is 176kgC/tree. The total amount carbon storage capacity of forest in Seoul is 454,783.73tC, of urban parks in Seoul is 80,567.97tC, and of street trees is 10,872,123tC. The total amount of carbon storage in the city limit of Seoul is 568,152.2tC. Kangbuk-gu and Gwanak-gu scored the highest for the total area and amount of carbon storage of forest and Dongjak-gu and Mapo-gu scored the highest for the parks. The total amount of carbon storage of Kangbuk-gu, Nowon-gu, Eunpyeong-gu, Jonglo-gu is larger than other districts. 3. Analysis of relationship between green spaces and heat island areas The distribution of heat index, tropical night, cooling/heating degree-day demonstrates that it has a close relationship with distribution of green spaces and impermeable paving due to land-use. To decrease temperature in the urban areas, it is essential to expend the total area of green spaces and to create green spaces and water ways on the right of way. 4. Guidelines to ensuring carbon reservoir and reducing carbon emissions The method to ensure carbon reservoir by expending parks and green spaces in the urban areas include creating and expending urban forest, ensuring green spaces along the right of way, expending landscaping areas, water spaces, and urban plazas of residential and commercial areas. To create and maintenance parks and green spaces, it requires to consider the adoption of biotope area factor within the total area of parks, planting tree types that has greater carbon storage capacity, production and utilization of energy within parks, management of biomass, allocation of parks and the network of greenways. 5. Policy recommendation The Urban Forest project should increase monitoring on expending carbon reservoir and build governance collaboration. Strategic approach to create urban forest focusing on the area where is needed is crucial. To maintenance street trees and to expend street trees, collaboration with other departments through regular meetings is necessary. Urban agriculture takes a important role as a type of carbon reservoir, but because study on current status of urban agriculture in Seoul is lack, it first need to conduct to collect information on urban agriculture in Seoul.
