Research purpose and content
Executive summary
1) Objectives and background |
The objective of this research project is to establish a biomass circulation system between urban and rural areas on the earth by returning organic waste and its nutrients accumulated in urban areas to rural areas and linking them to the restoration of livelihood infrastructure, especially agriculture and pastoralism, and the rehabilitation of degraded land. In ecology, biomass usually refers to the weight of plants and animals. These biomass resources are used for food, clothing, fuel, and building materials, and after resources are discharged in the form of food waste, human waste, sewage sludge, and wood waste.
The global societies are seeking to decarbonize their economies to zero emissions of CO2 and other greenhouse gases and transition to a carbon-neutral society. However, this is not an easy task due to the confused priorities of issues such as food insecurity, poverty alleviation, resource exploitation, and economic growth in different countries and regions. In this research plan, based on the current economic and social systems in Japan, Southeast Asia, and Sub-Saharan Africa, we believe that a transition to a carbon neutral society requires a shift away from combustion, and we will promote a shift from waste incineration to treatment processes that use decomposition, and will promote the use of biomass resources to restore degraded land and livelihood infrastructure for maintaining agricultural productivity. We will contribute to the promotion of biomass resource use for the restoration of the degraded lands and livelihood infrastructure for the maintenance of agricultural productivity.The project aims to create new values for the usefulness of organic waste and create a sustainable society by investigating the economic situation, food production, local perception of organic waste use and its actual use in each region, and by scientifically examining them from the perspectives of environmental and ecological sustainability, economic sustainability, and health and sanitation sustainability, in order to establish a biomass recycling system in urban and rural areas.
2) How does the research contribute to the solution of the global environmental problems? |
The global population is expected to grow to over 10 billion by 2050, and humans will have to survive on limited soil resource. There are fears that food production will not be able to keep up with demand, partly due to overuse of the land by agriculture and pastoralism, and partly due to soil erosion (FAO 2019). The food that humankind consumes needs to be clean, and the organic waste and manure that we throw away is abhorred by its filth. Sadly, the dogma of hygiene that humanity has developed based on science has prevented it from successfully positioning itself within the global system. In order for urban-based civilization to achieve sustainability in the future, it is necessary to accept human nature, which produces filth from cleanliness, to understand the importance of the material cycle and the rebirth of life, which produces cleanliness from filth, and to shift our thinking and values to position our existence in the earth system, which is separate from the earth system. A shift in thinking and values is necessary.
In Japan, Southeast Asia, and Sub-Saharan Africa, we will combine the multi-layered scales of agroecosystems in farming systems in each region, and national, regional, and global material cycles, and work to build a biomass cycle between urban and rural areas through the valorization of organic waste and the transformation of our consciousness. We will contribute to the transformation and sustainability of modern society.
In this research project, Japan, Southeast Asia (Laos and Malaysia), and Sub-Saharan Africa (Niger, Zambia, and Ghana) are the main targets. When considering the current status of material circulation of biomass and the construction of a circulation system, it is necessary to integrate the following levels: (1) households and rural cultivated lands as the unit of production, (2) regions (municipalities) as the unit of cities and watersheds, (3) nations as the unit of import and export, and (4) the global, and to consider regional and period We aim to create a sustainable society by using the concept of rescaling to change the regional scale in conjunction with the political and economic systems of the region and the times. The research topics are: (1) analysis of the current status of material circulation of biomass resources in arable land, farming villages, regions, and the world; (2) clarification of the decomposition mechanism of organic waste and verification of its safety; and (3) creation of new values toward the construction of biomass circulation. Rather than organizing independent research groups for Japan, Southeast Asia, and Sub-Saharan Africa, we will not establish research groups in order to analyze the material circulation linking rural and urban areas in order to verify the material circulation from production, consumption, and disposal in rural and urban areas. The material circulation required in each region differs according to the economic and social conditions of the city, and we will work together to build a material circulation system that will serve as a good practice from both regional and global perspectives.
1] Analysis of Current Status on Material Circulation of Biomass Resources
1-1 Material Circulation in Agroecosystems
This project aims to clarify agricultural patterns, arable ecosystems, and the distribution of agricultural products between urban and rural areas in three regions. The main subjects will be paddy rice cultivation and livestock production in Japan, paddy rice cultivation and forest production/forestry in Southeast Asia, and slash-and-burn and agro-pastoral complex in Africa. The project will also investigate the consumption patterns of farmers, as well as the regional and global distribution systems of agricultural products and the volume of agricultural products in circulation, using statistical data and other methods. We will also focus on fertilizer application techniques in rural areas, analyzing the actual use of materials such as chemical fertilizers, livestock manure, and compost. We will clarify the awareness and values of organic waste, and examine breakthroughs to promote the recycling of biomass resources.
1-2 Urban waste treatment and biomass resource accumulation
Waste emissions, treatment, and hygine will be investigated in cities in three regions. The study will examine the types and weights of household wastes, their collection and treatment methods, and the types and weights of waste materials in households, divided into human waste, sewage, and other waste materials. In Japan, we will focus on disposals and sewage treatment issues in the urban centers of Kyoto, as well as on the treatment of food waste and sewage sludge, and identify treatment processes centered on decomposition and issues for agricultural use. In Southeast Asia and Africa, garbage separation is not practiced to a great extent, and open dumping - landfilling of garbage by piling in the open - is the mainstream. The project will examine issues and measures for the agricultural use of organic wastes such as household and sewage sludge and the restoration of livelihood infrastructure.
1-3 Material Circulation around Import/Export of Agricultural Products (Calculation of Virtual Nutrition)
The Virtual Nutrition Map (VNP) will be created for 196 countries around the world using FAOSTAT (FAO's data on agricultural imports and exports) and other data compiled by the FAO. The VNP will create two types of maps: 1) how much nutrients (nitrogen, phosphate, potassium, etc.) do importing countries collect from all over the world and accumulate in their land, and 2) Two types of maps will be created to show how much nutrients are needed, assuming that importing countries produce agricultural products and timber, and the movement balance of nutrients for 196 countries in the world.
2] Elucidation of Decomposition Mechanisms of Organic Wastes and Verification of Safety
2-1 Analysis of greening and crop productivity by application of organic wastes
Field experiments will be conducted in paddy rice and field crops in Japan, paddy rice and forestry production areas in Southeast Asia, and field crops in Africa to verify the effects of application of organic wastes such as household waste, woody waste, and sewage sludge on soil properties, crop yield, and environmental restoration in degraded land.
2-2 Evaluation of decomposition mechanism of organic wastes
In the field experiment of 2-1, we will examine the input of organic waste to arable soil, its decomposition process, and the mineralization process, which becomes a form that can be absorbed by plants, focusing on the physical, biological, and chemical properties of the soil as well as weather conditions. We will also measure the CO2 flux on the soil surface to determine the CO2 emission/sequestration effects of organic waste input and revegetation, as well as the carbon sequestration in the soil, to elucidate the effects of greenhouse gas control.
2-3 Verification of Safety Regarding Agricultural Use of Organic Wastes
The health risks associated with the agricultural use of organic wastes are being addressed by developing a simple inspection system using EDX (X-ray fluorescence spectrometer), removal and dilution techniques for hazardous substances, and the use of organic wastes in agricultural applications. The project aims to eliminate health risks and improve the acceptability of organic wastes for agricultural use by developing a simple inspection system using EDX (X-ray fluorescence analyzer) and technologies for removal and dilution of hazardous substances.
3] Creation of New Values and Social Development Toward the Construction of a Biomass Recycling System
We will conduct experiments on the restoration of degraded lands and the improvement of agricultural and pastoral livelihoods through the transfer of materials from urban to rural areas and the input of biomass resources, and create manuals on the improvement of agricultural production and the restoration of degraded lands using organic waste in accordance with the actual conditions of each region. Based on the results of our research and the consensus of local residents, we would like to propose the social conditions necessary for the construction of a biomass recycling system based on decomposition, a change in the awareness of local residents, and the creation of social infrastructure in order to change the values of organic waste as "dirty, dangerous, and harmful" and to promote its valorization.
3-1 Development of Waterless Dry Composting Technology
Establish a dry composting technology that can process kitchen garbage and return nutrients to the soil using materials available in the surrounding area and a simple method. Developing technology to promote quick decomposition without producing odors. With the cooperation of the Westin Hotel Kyoto, we are continuing to process organic waste and monitor nutrients and bacteria.
3-2 Product Development of Compost Using Animal Dung Raised at Kyoto City Zoo
This dry composting system can efficiently decompose organic waste by using animal dung, including chicken manure. We have received animal droppings from nine species kept at the Kyoto City Zoo, including Asian elephants, zebras, giraffes, tigers, chimpanzees, gorillas, and mandrills, and are observing how the animal droppings and organic waste are processed. In the future, they aim to develop a compost product using animal manure.
3-3 Providing Integrated Study Classes at Elementary Schools in Kyoto Prefecture and Creating Class Manuals
Based on an agreement between RIHN and the Kyoto Prefectural Board of Education, RIHN provides integrated learning (exploration) classes at elementary schools in Kyoto Prefecture.
4) Expected results |
The expected results of this research project are: (1) to visualize the fact that the existence of huge cities and the import/export of food are a major environmental burden to ecosystems and material cycles in various regions; (2) to show that the utilization of organic waste from urban areas can help to restore tropical forests, green devastated areas as a measure against desertification, and improve local agricultural production. (2) To show that the utilization of urban organic waste can be useful for the restoration of tropical forests, the greening of degraded lands to combat desertification, and the improvement and enhancement of agricultural production in local communities, and to promote the creation of guidelines and manuals and a shift in values; and (3) To review our lifestyle and promote the development of urban infrastructure (garbage collection and treatment, sewage treatment) based on the premise that organic waste can be used for agriculture and green space regeneration.
5) Project organization and membership |
At the time of the transition from FS to PR, there were 15 research participants, but after repeated planning and trial experiments with dry-compost, the number of participants has now increased to 18, with the addition of Miho Saito (Kyoto University), who specializes in giraffe ecology, Hiromi Yamanashi (Kyoto City Zoo), who specializes in improving wellness of animals kept in zoos, and Akiyo Shioya (Kyoto University), an anthropologist who focuses on rural Africa.
Focusing on the material cycle between urban and rural areas is an unprecedented perspective on environmental issues such as desertification, destruction of tropical forests, and the emergence of degraded lands due to agriculture. In order to promote a common understanding among the members, we will not divide them into groups according to their expertise or region, but will try to ensure that the participants in the research have a common understanding of the current status of urban and rural areas in each region.
Challenges and achievements for this year
Project progress during the PR period
As this was the first year of the transition from FS to PR, we have started experiments, field research, and data collection while confirming the direction of research project.
In April 2023, project leader, Oyama was invited to the Westin Miyako Hotel Kyoto in Keage, Higashiyama, Kyoto, to give a lecture at the 1669th regular meeting of the Kyoto Lions Club. In this lecture, I explained the purpose of this research project, which aims to promote greening using organic waste from Niamey, the capital of Niger, and to realize food production and peace in the region. I also talked about research purposes in Kyoto City with the implementation of the practical project in mind, and was able to network with the executive chef of the Westin Hotel in Kyoto, as well as with the landscape gardening industry, traditional Japanese restaurant, vinegar industry, and sake breweries in Kyoto city.
In June 2023, Oyama began composting experiments on the balcony of his apartment in Kyoto City, and unexpectedly discovered that soil and rice bran alone generate heat and decompose organic matter without the use of water. Until now, there was a belief that water was necessary for the decomposition of organic matter by living organisms, but by intentionally causing drought and nitrogen starvation through microbial activity, methane generation and decomposition in an anaerobic environment can be avoided, and it is also clear that adding organic waste can quickly activate microbial activity and lead to rapid organic decomposition. Moreover, the addition of organic waste in the system stimulates microbial activity, resulting in the rapid decomposition of organic matter. Although unpublished, the fact that organic waste decomposition can be accelerated by intentionally creating drought and nitrogen starvation and using these conditions as a countermeasure is one of the directions for future technological development and this project. We are considering naming this method “dry composting”.
On August 31, 2023, with the cooperation of the Westin Miyako Hotel Kyoto, we began dealing organic waste by dry composting method, receiving cooked food waste and unheated scrap food every Tuesday and Thursday. As of January 2024, we continue to process organic waste at the hotel parking site.
Composting is the process of returning organic waste to the soil. In Japan, many people enjoy composting with weeds and kitchen waste. In urban areas, it is necessary to deal organic waste using simple methods that do not require large areas of land, large amounts of soil, or complex materials, and that avoid problems such as dirty water odors, small flies, and maggot infestations. By creating a drought condition of dry composting, these troubles can be avoided.
By establishing this dry-composting method at this research project, we believe that we can create an opportunity for consumers to think about food loss and kitchen waste in our daily lives by processing organic waste with familiar materials and in an easy and enjoyable way. In collaboration with the Kyoto City Zoo, we have received animal waste and are working on making compost using animal waste. In Sub-Saharan African countries such as Zambia and Uganda, they are studying the possibility of social implementation (business) by obtaining animal waste from pig farming and using organic waste from restaurants and supermarkets to produce compost for improving the soil of degraded land.
One of the challenges we are facing is the coup d'état and political instability in Republic of Niger, one of the main research countries. During our trip to Niger in May, the Minister of Environment visited our greening site, and we received praise and words of encouragement from the Minister. We waited for the rainy season and hoped that the greening would progress after June, but a coup d'etat occurred at the end of July, and five members of this project had to cancel our field activities in August. On November 15, JICA (Japan International Cooperation Agency) informed us that the Japanese government's Ministry of Foreign Affairs had decided to continue the ongoing project. Oyama built a greening site and put in urban waste under a JICA grassroots technical cooperation project, and was scheduled to observe the greening process in September. I gave instructions remotely and was able to obtain the necessary data, at a minimum, by our staff. With the withdrawal of the French ambassador and French troops from inside Niger, and the subsequent uncertainty regarding the response of neighboring countries and ECOWAS (Economic Community of West African States), the future of the situation is unclear. Although there are interventions in the West African situation due to the policy of the Japanese Ministry of Foreign Affairs, we would like to consider resuming our research activities in Niger, taking advantage of the change in safety information.
2) Amendments to research objectives, methodology and organization as applicable |
Not particularly. However, with compost works every Tuesday and Thursday at the hotel in Kyoto City and integrated learning classes at two elementary schools in Kyoto Prefecture every Monday, It became extremely difficult for Oyama to work everything on my own under the cross-appointment system. He is barely continuing his research and outreach activities by conducting research in collaboration with Akiyo Shioya, who started works at Kyoto University, but the project needs to develop its research team by hiring a new researcher. Initially, the plan was to employ one researcher and one research associate, but considering that the Kyoto Prefectural Board of Education has requested classes at five elementary schools in Kyoto Prefecture for the next fiscal year (FY2024) and that we need to expand our overseas field research, we plan to employ three researchers along with a research associate, for the FR period starting next fiscal year.
Self-diagnosis of research results in this year
1) Results achieved this year |
Composting is the process of making manure from household garbage, rice bran, chicken manure, etc. This is widely referred to as composting. Microorganisms are involved in the composting process, producing heat to promote fermentation and decompose organic matter. Water is usually added to the composting process, but this creates an anaerobic environment that causes decomposition, releases methane and foul odors, and often results in failure. In this research project, using familiar material, soil, rice bran and chicken manure, we do not add water, but generate filamentous fungi by administering fallen leaves, rice bran, and animal feces, and create nitrogen starvation over a week to induce active fermentation and rapid decomposition of organic waste under drought and nutrient starvation conditions. During operation, the temperature of the materials is monitored to determine the condition of the materials and when to put in the trash.
Many of the currently popular food waste disposers rely on electricity or external energy to force-dry food waste. In this research project, we utilize a natural process to process food scraps by monitoring the temperature of the materials to determine the timing of feeding. This natural process is strongly related to the intestinal bacteria of thermostatic animals, and its basic temperature is between 35 and 37 °C, suggesting a relationship with the basal body temperature of thermostatic animals. Based on this idea, we received nine kinds of animal feces, including chicken and beef feces sold at home centers, and Asian elephants, giraffes, hippos, zebras, tigers, chimpanzees, gorillas, and sloths kept at the Kyoto City Zoo, to examine how hotels dispose of food waste (unheated and cooked food) and how to treat it. The project is trying to establish techniques and recipes to promote the disposal of food waste.
Compost is created through digestion by thermostatic animals and fermentation (respiration) by microorganisms, but the methods and significance of composting vary from region to region. In Japan, emphasis is placed on the effective use of food residues, but in recent years, the fertilizing effect of composting has come to be strongly expected, partly due to the rising cost of chemical fertilizers. In the cities of Zambia and Uganda, instead of returning food waste directly to soil nutrients, pigs are being raised to produce pork, which is in high demand, and the pig manure can be used to improve the soil of the cultivated land. In Niamey, the capital of Niger, almost 80% of the total weight of the waste is sand and organic matter, and it is considered reasonable to put it directly into the degraded land for regreening the land.
The exciting part of this project is to devise a method of waste disposal according to the type of organic waste in each city, and to devise what to produce as a by-product along with compost. We would like to show that good practices from a local context, such as the eradication of hunger, food increase, the conflict prevention and the realization of peaceful societies. This can become good practices that solve global environmental issues.
2) Results can be evaluated as having overfulfilled |
The goal of this research project is to create a society that does not produce food waste by making good use of previously neglected organic waste. What enabled us to exceed our goals in the PR phase was networking among researchers in the project, between researchers and companies, the Kyoto City Zoo, the Kyoto Prefectural Board of Education, elementary schools, and children. I would like to explain three points here.
The first point is the possibility of material cycle and environmental education in cooperation with zoos. Zoo animals feed according to their own dietary behavior. The Kyoto City Zoo has 108 species of animals, and they differ in the food they eat, such as herbivorous, carnivorous, and omnivorous. In response to Kyoto City's financial difficulties, the Kyoto City Zoo has called on citizens and industries to donate vegetables and fruits from Kyoto City and its surrounding areas. The zoo also plans to make effective use of animal feces, most of which is disposed of as industrial waste, as compost, and offer it to visitors as a subject for environmental education. Miho Saito, our collaborative researchers, has already given a lecture at the Kyoto City Zoo, and is planning to give a lecture as part of this project.
The second is to create compost using organic waste from hotels in Kyoto City and animal feces from the Kyoto City Zoo, to clarify the mechanism of composting, and to establish techniques and recipes for temperature control. In addition, we are in the process of verifying the compatibility of animal feces with the garbage to be processed. For example, the feces of herbivorous and fruit-eating animals such as elephants, giraffes, and gorillas are good for processing vegetable waste such as vegetable scraps and fruits, the feces of tigers and leopards are excellent for processing proteins such as meat and fish, and the feces of omnivorous animals like chimpanzees are compatible with all types of waste. The working hypothesis is that there may be different types of litter that are compatible with the gut flora associated with food habits and preferences, such as omnivorous animals like chimpanzees, which are compatible with all types of food waste. This hypothesis is that the process of digestion by intestinal bacteria in the bodies of thermostatic animals may exist in the form of fermentation (decomposition) in the soil outside the bodies of these animals.
We also plan to develop the product as the next step in the clarification of the decomposition (fermentation) process. These include "tomato manure made from hippopotamus dung," "soil conditioner made from elephant dung," "potato soil rehabilitation from giraffe dung," and "sunflower soil made from silver back gorilla dungs," that could be sold at souvenir shops in the Kyoto City Zoo and Botanical Gardens in Kyoto Prefecture.
The third point is to outreach activities based on the research results to society by providing classes at elementary schools in Kyoto Prefecture based on this concept, technology, and recipes of “dry compositing”. For the disposal and effective utilization of food waste, it is necessary to expand the scope of processing operations to small grids, such as households and companies. In November 2023, two elementary schools in Ide Town, southern part of Kyoto Prefecture, we plan to make classes on food waste treatment and compost making in three fifth-grade classes as part of comprehensive learning. In the next academic year 2024, in consultation with the Kyoto Prefectural Board of Education, we plan to increase the number of schools offering the classes to five. The program hopes to foster the discovery of the process and mystery of how soil is created from food waste, the appeal of science, awareness of environmental issues, and a vision for building a future society. It has also been reported that mental illnesses are reduced when children touch and play with soil. We plan to conduct a questionnaire survey of elementary school students to find out what they think of the project, and use the results to develop future classes. The major achievement of this project is currently that the networking and inspiration allowed us to clearly identify the budding and potential of this project.
3) Points to be evaluated that the goals were not reached |
The technology and concept of “dry composting” has not been written up in any research papers at all, and has only been discussed with a small number of collaborative researchers. Many researchers in this project do not have a clear image of how the creation of material cycles between urban and rural areas will lead to the prevention of land degradation, ecological restoration of tropical forests, and restoration of productivity of cultivated land. The material cycle between urban and rural areas is more difficult than it sounds, and I believe that brainstorming sessions are further needed among the collaborative researchers to determine how to specifically link this to solutions to environmental problems.
I would like to further deepen our common understanding by inviting our co-researchers to actively participate in the research review and debriefing sessions and EREC to listen to the presentations and have discussions.
4) Notable achievements and challenges as to contribution to the RIHN programs |
The Matsuda Program, "Towards a Global Environmental Culture by Articulating Science with Indigenous Knowledge," aims to introduce a cultural perspective into research that contributes to solving global environmental problems, and to examine the processes that lead to the transformation of people's behavior and values. In this project, in the research countries of Zambia, Niger, Ghana, Uganda, Malaysia, Laos, and Japan, we will focus on understanding how local people perceive and respond to the decline in agricultural production, the emergence and expansion of degraded land and tropical deforestation. Our major contribution is to specifically address local environmental issues by linking various industries, such as hotels, restaurants, breweries, landscaping, farmers, and pig farmers in the city. The efforts to address local environmental issues in this project can also have meaning from a global perspective, such as the restoration of degraded land and the ecological restoration of tropical forests, and will lead to changes in people's behavior and values in order to establish a material cycle between urban and rural areas. We will strive to make a significant impact not only on the academic world but also on society.
Future tasks
Research plan for next year
The next academic year is the first year of our FR. We plan to focus on understanding the current situation, networking with local research institutions, government, and municipalities, and setting the experimental plots.
The political situation in Republic of Niger has been unstable since the coup d'état took place, and Oyama is collecting security information and gather research data from local staff remotely. If the political situation improves and the Japanese Ministry of Foreign Affairs' safety information improves to Level 2, I plan to travel there for a short period to check the security situation and exchange information with local counterparts.
Harada, Hara, and Oyama are the main survey targets in Zambia. Harada will start a JICA/JST SATREPS project in the next academic year, which will be linked to this project. Harada is conducting research in Lusaka, the capital city, and in Mufumbwe District, North Western Province, and plans to observe experimental plots constructed in AY2023. Our counterparts are the Institute of Economic and Social Research and the Department of Geography and Environmental Sciences at the University of Zambia, which has an interdepartmental and inter-university academic exchange agreement with Kyoto University. Lusaka District commissioner promises to make corporation to our projects.
In Uganda, Seera, Nakazawa, Suzuki, and Oyama are the main research subjects. We plan to construct an experimental site in Mukono District, a suburb of Kampala Metropolitan Area, and Seera is already negotiating with the landowner. According to the landowner, the soil fertility of the crop field is low and the land is not currently suitable for growing crops. In the coming year, Seera plans to investigate the materials available and the local knowledge for soil improvement.
In Ghana, Kirikoshi, Ushiku, and Kunieda continue their research. Kirikoshi has created 5m square experimental plots in the forest and savanna zones, and will observe what kind of plants will grow in the plots by throwing local domestic wastes. Anderson (1952) and Abbo et al. (2005) have proposed the "dump-heap hypothesis" as the origin of agriculture. We intend to determine the changes in plant species that grow as a result of the accumulation of garbage and nutrition from local residents.
In Japan, research activities will be conducted mainly in Kyoto. We continue dry composting at the hotel in Kyoto City using food waste from the restaurant. We aim to establish this method that does not fail due to seasonal and temperature changes in dry composting efficiency, bad odor, maggots, and small flies. We will also increase the number of classes offered at elementary schools in the prefecture to five, and promote the creation of manuals for composting as the integrated learning classes at elementary schools. Field trials are continued for animal dung compost made from animal waste from the Kyoto City Zoo and hotel food waste. We will ask a third-party analysis of the chemical and biological properties, as well as toxic heavy metals, and work with designers and promoters to explore the possibility of commercializing the product. If the project proves to be successful, we hope to promote social implementation (business) and even consider the establishment of a venture company originating from RIHN.
Tasks for the next fiscal year onward
1. The main focus of this project, the idea of agricultural utilization of urban organic waste and ecological restoration, has not been focused on in the academic world, and may be a difficult topic to initiate, especially for researchers in the field sciences. During the FS and PR periods, I have repeatedly held online and face-to-face workshops, but I believe that we need to be creative in how we involve the research collaborators. For this purpose, I myself want to make field research in the fields of Malaysia and Laos.
2. I don't feel that there is anything special about it. However, the project management and paperwork effort due to cross appointments is more than I expected. I wonder if there is any way to manage the procedures for field research, concurrent work, and duplication of e-learning. Although our time and effort are very limited, I would like to explore how we can create a meaningful relationship with other projects and collaborate with them.
In particular, I would like to thank the Research Planning Subsection, the Public Relations Unit, and all the other RIHN staff for their hard work and support. I have been receiving meaningful comments from Program Director Matsuda on a daily basis.
