3. This research aims to make clear the farmland restoration volunteer attribution and consciousness, and the volunteer experiences before-after of this disaster of the Torrential Rainfall in Northern Kyushu in July 2012. The questioner research was carried out to NPO Sansonjyuku’s volunteer, 897 persons by post mail, and three private company by web mail from Nov. 27th 2014 to Jan. 31th 2015. As a result, post mail recovery rate was 30.2%. Most high portion of volunteer occupation etc. were the private company worker, 40’s and Fukuoka city urban peoples. Volunteer recruiting was carried out by people who have experience with NPO Sansonjyuku before disaster. The volunteers worked 2.97day per person during one year and eight months as average, and the repeat rate was 49.0 %. In terms of volunteer experiences of before disaster, 33.7% volunteers had the disaster volunteer experience, and 76.1% volunteer had experience that had been visited to this region. As for NPO Sansonjyuku volunteer seems around ten percent both before and after of disaster. Thus, this research confirmed that the importance of activities in farm village from before the disaster, not only the conservation volunteer but tourism so on..
4. 朝廣 和夫, Support for farmland restoration after flood disaster in hilly and mountainous areas: Cases affected by torrential rainfall in Northern Kyushu, Japan., Developing Sustainable and Resilient Rural Communities in the Midst of Climate Change: A challenge to disaster preparedness and mitigation strategies UP -SURP in cooperation with the DENR and Asia Center Japan Foundation Crowne Plaza Manila Galleria Hote, 2015.12, A considerable amount of farmland was destroyed by a flood disaster that struck in 2012 in Yame and Ukiha, in Fukuoka prefecture in the northern part of the island of Kyushu, Japan. This presentation is a case study of the volunteer farmland restoration activities that were carried out in the hilly and mountainous areas after the flood. The purpose of this study is to outline the activities in three regions and to show the character of the volunteer farmland restoration groups. Interview surveys were conducted with the manager of each volunteer group, and data on the process of forming volunteer groups, the monthly process and distribution of activities, and intermediaries between affected farmers and volunteer activities were collected in field surveys. The results revealed the formation of three types of NGOs after the disaster: “civic groups for conserving lands in and near the village and neighboring mountains”; “cooperative organizations between residents and governments”; and “organizations under administrative instructions.” Residents in each region had experienced conservation activities for terraced paddy fields with residents in urban areas before the disaster, indicating that NGO activities before the disaster are the base of disaster volunteers for farmland restoration.
This study is a result of the “Study on Restoration Support Models for Farming and Forestry after Water Disasters in Hilly and Mountainous Areas“ in the promotion project for strategic creative research in 2012 (social technology research and development) of the Japan Science and Technology Agency. This study was published on Journal of Disaster Research (JDR Vol.10 No.5 Oct. 2015) with others. This special issue was coordinated by Dr. Haruo Hayashi (National Research Institute for Earth Science and Disaster Prevention, President) as title on “Special Issue on Creating Community-Based Robust and Resilient Society”. It is very glad that share these experiences in this conference.

15. Asahiro Kazuo, Ayane Nakagaki, Md. Abiar Rahman, Masakazu Tani, Current conditions of social forests in Teknaf and Shilkhali ranges of Bangladesh, 5th International Conference on Environmental Aspects of Bangladesh (ICEAB), 2014.09, This study discusses the current conditions of social forest (SF) in Teknaf and Shilkhali ranges in 2013, ten years after the first implementation of the SF scheme in Teknaf. Field and interview surveys were carried out from 9 to 17 September 2013 and 4 to 9 March 2014 and normalized difference vegetation index (NDVI) was analysed from the satellite imagery taken in 2010. Correlation matrix was used to describe the relationship between these factors. We found that 70.3% of SFs was with active cutting of the trees until 2013, but in eight Acacia spp. SFs, thinning management was delayed from the predicted SF regulations; in 11 SFs, thinning was done properly, and five broad leaved and seven cleared SFs were confirmed. These results were mapped, to show the differences in SFs current conditions as well as the local measurement requirements. The findings would help to conserve the SF in the study area..

18. This research focused on the hilly and mountainous area of Yame City, Fukuoka Prefecture, which suffered damage due to the heavy rains that occurred in the northern part of Kyushu in July 2012. The objective of this research was to identify the distribution of damage to agricultural land in the Yame City area and the districts in which it was concentrated. In addition to characterizing the damage, the research was aimed at revealing the activities of aid agencies. To conduct this research, the carried out questionnaire survey by Yame City, the disaster report on the agricultural land and facilities was analyzed, and interviews were conducted to an NPO, and the leaders of the local. The results of our research led to the following conclusions: (1) Following a comparison of the reported disaster densities in the managed cultivated areas, it was ascertained that the damage was concentrated in Jouyo Town, Hoshino Village, and Kurogi Town, with totals ranging from 170.5 to 299.7 incidents/km2, and particularly in the Kasahara District of Kurogi Town, with a total of 1503.1 incidents/km2. (2) The damage to roads in the semi-mountainous regions and it was shown that this situation exacerbated the difficulties of the recovery. (3) It was reinforced that the presence of an NPO with a base in the disaster area meant that the initial support for the recovery was highly effective..

29. This research aims to clarify the relationship between image properties of aerial photograph and structural factors of Castanopsis cuspidata coppice woodland and Chamaechiparis obutusa artificial forest, and to develop an algorithm of tree crown analysis using the images. The aerial photographs were taken in May, 1999, the season of flowering Castanopsis cuspidate, and converted to monochrome 45cm ground resolution digital images. Fourteen plots were chosen in the field to measure vegetation and forest structure. Correlations were analyzed between image properties such as SD (standard deviation) and CF (cumulative frequency of tree crown edge) and forest structural factors such as tree crown area, tree density, relative illuminance under tree crown, etc. As a result of only Chamaechiparis obutusa artificial forest, a -0.79 correlation between SD and CF was obtained. Also, a 0.79 correlation between SD and the relative illuminance under tree crowns was found. Furthermore, in terms of CF, a 0.72 (tree crown area) and a –0.82 (tree density) correlation was found. The results suggested that these images contained the information of the tree crown..
