      Direct subsidy for crop insurance premiums paid by producers is widely adopted by policy-makers in many countries. It is generally believed to be a good device for income transfer to rural producers. In the recently launched crop insurance program in China, it is also employed as an incentive tool to encourage per-producer output and discourage rural-to-urban migration besides its traditional role. This research develops a dual-economy model to check three essential hypotheses that may support the Chinese government’s decision. The model incorporates subsistence constraint in consuming agricultural products, which essentially changes the yield-revenue relationship of agricultural products. The analytical results from the model do not support these plausible hypotheses. When rural producers insure their crops with partial coverage, output at the individual level drops rather than increases. Meanwhile, the provision of insurance plus premium subsidy crowds the agriculture sector with too many laborers engaged in agricultural production. In this sense, government subsidy for crop insurance premiums induces efficiency loss rather than gain. The authors suggest that a comprehensive cost-benefit analysis should be carried out comparing premium subsidy and other types of risk-reduction and income-transfer programs, for the better use of government budget.

      This paper aims to determine the critical factors associated with life recovery for disaster victims. Huge disasters undoubtedly impact and change lives. Life recovery is a subjective issue that differs from social values, living conditions, loss, etc. Although the importance of life recovery has been previously addressed, international assistance for victims in disaster-affected areas continues to be directed toward conventional needs such as housing reconstruction and livelihood development, often failing to fully consider life recovery. In this paper, we try to explore the critical factors associated with life recovery through a case study of Indonesia, which has recently experienced two massive natural disasters—the Indian Ocean Tsunami on December 26, 2004, and the Central Java Earthquake on May 27, 2006. By conducting field studies, we highlight and examine the critical factors relating to life recovery in Indonesia. Thereafter, we analyze the results according to the societal background of each community, especially as it relates to social capital.

      This study intends to adopt a geographical approach to building a region-type index associated with recovery, which aims to examine the impact of ongoing demographic transition in the context of the expected the Tokai-Tonankai-Nankai Earthquake. A great amount of population census data is applied in building the index that comprises 3 demographic transition patterns that represent the various degrees of regional self-sufficiency in a disaster. Applying the index to the population census data of 2005, with the anticipated seismicity in 4 appointed scenarios via GIS mapping, a place assessment is presented to examine the impact of a possible population demographic transition order issued in pre-disaster recovery planning.

      The Vitae System model is referenced to provide a systematic framework for the adaptive evacuation strategy in a life-critical situation by integrating its three fundamental elements-survivability, vitality and communication. A preliminary model is proposed in the context of evacuation from a water related hazard. A multi-agent based evacuation simulation system is prototyped combining hydraulic model data for the case area of the Oike underground space in Kyoto, Japan. The impact of facility arrangement on evacuation decision-making is demonstrated.

      This paper introduces a challenge of mutual knowledge development in the implementation of the Yonmnekaigi system as a participatory workshop method to improve sand mining management of local communities in Merapi Volcano of Indonesia. It was applied for the formulation of action plans on community-based sand mining management in Pilot Project implemented by Gadjah Mada University in Yogyakarta, Indonesia under Urgent Disaster Reduction Project for Mt. Merapi, Progo River Basin (JICA Loan No.: IP-524) executed by Directorate General of Water Resources, Ministry of Public Works, Indonesia. A participatory workshop method called the Yonmenkaigi system method, originally developed in a local community in Japan, has the following main steps: carrying out SWOT analysis, completing a Yonmenkaigi Chart, debating between groups, and presenting the group action plan. A case study carried out in the Kemiren village, Yogyakarta, Indonesia in August 2009, demonstrates how residents who are interested in disaster mitigation and management in a local community can collaboratively develop an implementable action plan for Sand Mining Management of local community. Based on the above case study, this paper categorically itemizes and formalizes two types of knowledge development needed for introducing the Yonmenkaigi system method to the cases in Indonesia. The first type of knowledge development is that type of knowledge which is generated as an outcome through the process of implementing a whole set of the Yonmenkaigi system. The second type is shown to be modeled as mutual knowledge development between “seed knowledge providers” and “custom knowledge providers”. Illustrations are made from the field work results and the two types of knowledge development have been specifically described and analyzed.
