Also, since the combination and fusion of the complex technological elements are important, the discussion will be from new viewpoints including the drafting of whole scenarios in R&D, improvement of vulnerability of the system, and the construction of a portfolio and social implementation. Also, the author currently belongs to the environmental science department of a university, and would like to state the basic concept on the role and collaboration of industry, government, and academia in a technological development, mainly from the academic stance.2 Current situation and future of technological developmentIn the development of GERAS, various types of analysis models were created in the past 10 years, and were applied to the actual environmental pollution problems. It is now employed in over 1,500 Japanese companies and organizations, and it has been established as a standard risk management tool. The users suggest various future developments, such as making it usable for economic risk evaluation in addition to environmental risks, or incorporating risk evaluations to social systems for soil environment and possibly to legal systems. As the next step, we are developing the economic model to quantify the cost-effectiveness of the remediation measures. We are also developing a submodel for the impact of soil pollution measures on the living environment and the ecosystem. In the new development, risk based decision-making and investigations of environmental economy are necessary, and the introduction of a methodology to fuse the humanities and 1 IntroductionVarious reactions have been received since the publication of the paper on the Geo-environmental Risk Assessment System (GERAS) published in Synthesiology Volume 1 Number 4 (2008)[1] four years ago. There are direct requests from companies and local governments for the use of GERAS in environmental measures, and the paper has played a major role in its social diffusion. The paper has also been cited in many researches on risk assessment. However, more essentially, there were many comments on the methodology for establishing and diffusing the process and on the synthetic thinking that led to the development of GERAS. In another series of comments, constructive proposals and new viewpoints were provided, such as the optimal scenario as well as ways to fuse the elemental technologies in order to promote such complex technological development.Most of the environmental technologies are clusters of diverse technological elements, and they realize products or social systems through analyses and processing of vast amounts of information. Although there are numerous R&Ds for technological elements, the technique to combine them is lacking. Ultimately it is necessary to integrate them and to fix them into society by maintaining the socioeconomic perspective. After the Great East Japan Earthquake of March 2011, there were high expectations for new developments for helping disaster restoration efforts by diffusing environmental technologies quickly in society.In this paper, I shall discuss the scientific and sociological - Case study of the development of GERAS and its evolution-A portfolio analysis of composing elements using a synthesiological method has been carried out for complex technology development, which involves fusion of various technology systems and elemental technologies. To assess the method’s effectiveness, a case study was conducted on GERAS (Geo-environmental Risk Assessment System), a system for soil contamination diagnosis. The analysis spanned the entire development phase, from the generation of research ideas to the dissemination of results to society. The benefit of using this method was greater ease in system design and social implementation, through the analysis of critical components in the developmental process. I also discuss applying this method to novel areas, such as the development of technology for reconstruction after The Great East Japan Earthquake disaster.Portfolio structuring and social implementation in the development of complex technology Keywords : Environmental risk, risk assessment, soil contamination, synthesiology, portfolio structure[Translation from Synthesiology, Vol.6, No.3, p.180-186 (2013)]Takeshi KomaiGraduate School of Environmental Studies, Tohoku University 6-6-20 Aoba, Aramaki, Aoba-ku, Sendai 980-8579, Japan *E-mail: Original manuscript received May 10, 2013, Revisions received June 18, 2013, Accepted June 19, 2013
