[HCG22-07] A Preliminary Study on Benefit Evaluation of Disaster Prevention in Urban Open Space in Indonesia
キーワード：都市オープンスペース、防災公園、インドネシア
This paper examines the methodology to consider what kind of disaster prevention functions people want in urban open spaces. Urban open space is an essential element for urban disaster prevention because of the following open spaces characteristics: (1) space that is not covered by structures or buildings, (2) space where natural environmental elements take precedence, (3) space with openness, and (4) space with flexibility and diversity of functions that are not limited.
This paper focuses on Indonesia as a country with many natural disasters. Indonesia has experienced many natural disasters such as earthquakes and tsunamis in different parts of the country, including the Palu earthquake and tsunami (2018), the Padang earthquake (2009), the Yogyakarta earthquake (2006), and the Aceh & Nias tsunami (2004). The role of urban open space in natural disasters has been recognized globally. However, it isn't easy to establish open space in a country like Indonesia, where the population is concentrated in cities, and the population density is overcrowded.
In Indonesia, there are no cases of measuring the disaster prevention functions of urban open spaces. This paper discusses the importance of public interest functions of disaster prevention parks. This paper aims to clarify the problems and issues and the importance of the public utility functions in disaster prevention parks using CVM (Contingent Valuation Method). Using CVM, it is possible to identify the importance of the public utility function of the disaster prevention park based on the preference of the Indonesian people. Furthermore, it also evaluates the value of the urban park in monetary units.
This study chose conjoint analysis among CVM because it can evaluate each function of disaster prevention parks. The indicators of the analysis were developed reflecting the knowledge of urban disaster prevention parks in Japan. The following five attributes were set: (1) trees and other plantings, (2) disaster emergency response facilities, (3) rescue operation facilities, (4) development of recovery and reconstruction centers, and (5) annual taxes per household. This study was conducted to examine the appropriateness of the attributes and the reasonable differences in the amounts. In order to explore the validity of the created index, a questionnaire was distributed to Bogor Agricultural University students for examination. This survey revealed that university students' interest in disaster prevention parks is high. It means positive discussions can be held for their establishment. As a pre-survey, this study allowed us to collect preliminary information for a survey to be conducted on the general population.
