Outline Activities
Research Theme:Nature Conservation and Biological Habitat Restoration in Suburban and Rural Areas.

“It is not half so important to know as to feel.”

These are the much-quoted words of Rachel Carson, from her essay “The Sense of Wonder.” The concept of “conservation” in “conservation of green spaces” is sometimes explained in the United Kingdom as being “like raising children.” “Taking care” of “nature” (or children)—that is, not standing back and simply letting things happen—means to take a hands-on, eyes-on approach to nurturing, or maintaining relationships. Such attitudes and behaviors are necessary for families, for communities, to share healthy lifestyles, to share time and space, with nature in a sustainable manner.

This laboratory targets green space environments in suburban areas and rural communities, which are nurtured within such relationships between people and nature. Through human conservation management, the biodiversity, amenities, aesthetics, production of agricultural and forestry products, disaster prevention, and other public-interest functions of green space environments are maintained. The laboratory’s research aims are to provide society with conservation designs (plans/designs) that contribute to the relationship between people and nature by carrying out research and education, making recommendations, and implementing projects in cooperation with local residents, government agencies, and specialists, committing to social issues in order to promote sustainable community living environments as well as conservation/regeneration of the natural environment, analyzing historical and natural contexts, and clarifying conservation mechanisms. Our ultimate goal is foster human resources capable of sensing and conveying the beauty of the environment.

Our main research themes are conservation of secondary nature and forests, ecological research of secondary woodlands, research related to rehabilitation of agricultural land through mutual assistance in disasters, research related to volunteer tourism, and research related to green space conservation in Bangladesh. With the flow of these research themes, going forward we seek to develop various activities that can better address issues facing the real world:

What form should secondary nature/forest conservation models take in the future in order to be successful as small-scale businesses?
How should agricultural villages in hilly and mountainous areas develop amidst the depopulation of local society?
How should value be added to traditional crop plants and landscapes, and how should these be conserved through industrial development?
How can communities capable of coordinating mutual assistance and cooperation be created?
Can secondary nature/forest conservation topics be developed through art?

Current and Past Project
  • The research to explore the relationship between forest devastation and poverty in the Bangladesh Teknaf peninsula have been carried out in these eight years, launched from around 2009, by Professor Masakazu Tani as a project leader. From the standpoint of conservation of green spaces, I have conducted surveys on the situation of the homestead garden, forest vegetation and social forest, and reported on it. From 2015, Prof. Tani starts "Research on the Relationship between Forest Disappearance and Poverty in the Regional Ecosystem Framework" as "Fundamental Research (A) Overseas Academic Survey". I’m researching in particular, the potential productivity of forest resource, which mean, biomass productivity in the forest in a year. The purpose of the research is to calculate the people consumption and balance of biomass productivities. The village survey is carrying out by Prof. Tani laboratory and try to clarify whether people's consumption is large or the forest production is high. The design of people's way of living and the design of forests will differ depending on their quantity.
  • Development of Support Model for Agriculture and Forestry Land Conservation and Resilience after Flooding Disaster in Hilly and Mountainous Areas
  • The objective of this research is to devise a model for the conservation of biodiversity without sacrificing residents’ livelihood in the Teknaf ECA designated by the government of Bangladesh.

Papers
1. 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..

3. Many farmlands were destroyed by big flood disaster in 2012 that was occurred in Yame and Ukiha city, Fukuoka prefecture at northern Kyushu, Japan. In this paper, I described the case study that has been deployed the volunteer activities for farmland restoration after the flood disaster in the hilly and mountainous areas. The purpose of this study is to clarify the outline of the activities in three regions and to show the types of the volunteer groups of farmland restoration. Interview survey was conducted with each volunteer group’s manager and collecting that materials. Field survey was also carried out along with the manager through June to September 2014. It was found that the volunteer group’s activity types were characterized into three types. First, “Satochi-Satoyama conservation volunteer group type” that has been works from before and just after the disaster; second, “Residents-administration group type” and third, “Administration group type” who started their works few months after the disaster. Lastly, the distribution of activity areas, the first group was unevenly distributed due to their activity experiences on disasters in former years, the other groups were widely covered the area because of the needs by the local demand..
4. 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..

6. This is a report of the “Student Workshop for Recon-struction Assistance to the Tohoku-Pacific Ocean Earthquake.” The disaster occurred on March 11, 2011, and the reconstruction support activities were con-ducted by the executive committee of the Japanese Institute of Landscape Architecture in Minamisanriku-cho, Miyagi prefecture, from September 4, 2011 to May 2, 2012. The activities consisted of three phases—phase 1: on-site workshop, phase 2: polishing of the student’s proposal and presentation of a report at the academic conference, and phase 3: reporting of activities to the local residents. The following four results were drawn from these educational activities: (1) perspective of landscape design, (2) activities were carried out six months time after the earthquake occurred, (3) education as an opportunity for college students, (4) collaboration with local stakeholders, universities, and companies. On the other hand, several issues were noted for future activities of educational institution in disaster affected local areas: (1) safety measures to reduce disaster risk at the site, (2) making a sincere relationship with the local people, (3) fund-raising. In conclusion, work in disaster areas is crucial and further contribution from our design education should be enhanced..

11. 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..
