Programme Information

The students of Akita Prefectiral University (APU) organised "Student Collaboration for Sustainable Development in Nomadic Life" from 16th of August to 30th of August 2008 in Mongolia as one of the 2008 University Students Exchange Programme within the framework of the International Exchange Programme between Japan and Other UNESCO Member States for the Promotion of International Cooperation and Mutual Understanding. The students of APU have been engaged in the `Sustainable Development' work as a part of their `Independent Research' initiatives under the guidance of professors. The `Independent Research' programme of APU has been approved by the Ministry of Education, Culture, Sports, Science and Technology as a "Support Programme for Distinctive University Education". Under the main theme of `sustainable development', the students of APU are exploring the practical application of ecological energy system in the Himalayan region of Nepal, special for the benefit of small and backward communities where there is no existing electricity supply. Actual use of solar energy systems assembled by the students to illuminate primary school building and Buddhist temple are some of the outcomes of this initiative. Last year, the students of APU expanded their activity to a Mongolian Nomadic village. There had been ongoing academic research collaboration between APU and three Mongolian Universities (Ulaanbaatar Erdem Oyu University, Mongolian State University of Agriculture and Mongolian State University of Science and Technology). The academic research collaboration was enhanced under the UNESCO/Japan Funds-in-Trust for the Promotion of International Cooperation and Mutual Understanding.



The main aim of this proposed programme is to conduct collaboration of the field study between Japanese and Mongolian students under the supports of specialists in both countries, which brings both university students to discuss, comprehend and develop insight concerning the challenges of `sustainable development'. APU students agreed with Mongolian students to cooperate in carrying out the following activities; (1) Learning of current issues on the global development through lectures given Japanese and Mongolian specialists. (2) Mutual understanding through the discussion of the experimental activities on the sustainable development. (3) Experience of nomadic life by staying in a traditional Mongolian tent (so called a `Ger' house). (4) Collaboration work together with Mongolian students to assemble a solar power system in a nomadic village. (5) Operation of the solar power system, discussion on the test results and modification of the system to improve the performance. (6) Collaboration work in assembling a light trap system to capture insects. The light trap shall be operated, using electricity produced by solar energy. (7) Study on the effect of the light trap to prevent the grasses and vegetables from insect damages. (8) Soil analysis to check its degradation due to the overgrazing and overcultivation. (9) Visit to Karakorum, old town inscribed to world cultural heritage by UNESCO, to learn the Mongolian history and culture.



Day 1 (16 August 2008, Saturday) Departure from NRT and Arrival at ULN At 13:30 we left Narita Narita Airport on flight OM 502 of Mongolian Airlines( MIAT ) for Ulaanbaatar. At 17:45 we arrived at Ulaanbaatar Airport. Prof. Alimaa and Mr. Katachulun welcomed us there. After short rest at the hotel "Gest House" near the center of Ulaanbaatar, we were invited to dinner by Prof. Dorj, the general director of Erdem Oyu University. Day 2 (17 August 2008, Sunday) Short city tour and visit to Nature History Museum Because it was Sunday, opening ceremony was postponed to next Monday. In the morning we had rest in the hotel, and after lunch, Mr. Katachulun, a teacher of Erdem Oyu University, took us to the short tour in the heat of the city (Fig.1). We visited the Natural History Museum, which consists of 40 halls including geography, flora, fauna and fossils wings. The main attraction was a large collection of dinosauls fossils and skeletons, some of which are famous around the world (see Fig.2).

Day 4 ( 19 August 2008, Tuesday) am Visit to Mongolian State University of Agriculture We met Prof. B.Byambaa, the president of the university, member of Academy of Sciences of Mongolia together with Prof. B.Baasansukh, vice president and other board members. Prof. Byambaa gave us a brief introduction of the university. 8 faculties, 45 departments 7000 undergraduate students, 1400 graduate students, 450 teachers 16 collaboration projects with Japanese universities. He expressed warm hearted welcome to us and expectation of the success in our student collaboration programme. We expressed our appreciation of the great supports including the arrangement of the research site at Bornuur.

Fig.16 Meeting at the State University of Agriculture with Board members. After the tour in "The Mongolian Nomad's Culture and Civilization Museum", we visited to the laboratory of Prof. B.Buuveibaatar where studies on the solar power generation as well as the wind power generation were carried out. Solar heater was also under development. Then we visited the laboratory of Dr. Solongo. Her professional research field was "Soil Science". She explained us on cultivation of vegetables in Bornuur. There, the land has been cultivated for ten years without artificial

fertilizer. She was studying soil recovery.

pm Preparation of tools and materials for field work at Bornuur Half a day was spent to prepare experimental devises for the field work. We intended to buy batteries, electric cables and lumps to build up solar power system. It was difficult to find high quality batteries suitable for solar power system. We had to give up to obtain high quality batteries. Foods and bottles of mineral water were also needed for 5days stay in nomadic land.

Day 5 ( 20 August 2008, Wednesday) Transfer to Bornuur by bus with Mongolian Students State University of Agriculture has the experimental field at Bornuur where is about 150km far from Ulaanbaatar to the north. It was our experimental field. We left Ulaanbaatar to Bornuur to conduct the field work with 6 Mongolian students for 5 days. Fig.19 The site for our experiment

From Day 6 ( 21 August 2008, Thursday ) to Day 9 (24 August 2008, Sunday ) During 4 days from 21 to 24, APU students conducted the following three collaboration works with Mongolian students. (1) Construction on a solar power system and its performance tests. (2) Construction on a light trap and high voltage system to capture insects. (3) Soil investigation There, together with Mongolian students, we experienced the different way of living from modernized one in Japan. The activities and experiences for these 4 days are summarized below. (1) Construction of a Solar Power System and its Performance Test In the morning on 21 August, construction of solar power station was started. The maximum out-put power of the solar cells were 240 W. The frames to support the solar panels were assembled by Japanese and Mongolian students.

Fig.20 Construction of solar power cell system In the afternoon on 21 August, the control system was connected to the solar cells. From 22 to 24 August, by charging and discharging the solar energy to (or from) batteries, the performances of the system were examined.

Fig.21 Assembling the control box to operate the solar power system

(2) Construction of a light trap system with high voltage nets In the afternoon of 21 August, a light trap system was constructed under the cooperative work with Mongolian students. It consisted of 4 fluorecent lumps and metallic nets working at a voltage of 7000V. Insects were attracted to the lumps by the violet light and were killed by the shock, touching the high voltage nets.

Fig.22 Construction of a light trap system After the construction of the system, it was connected to the solar power system. Operation tests were carried out at night. In the morning of 23 and 24 August, the total weight of the insects captured by the trap was measured. Survey of the insects living in the pasture was also conducted.

(3) Investigation of soil In order to understand geographical composition of the research field, mapping of the experimental site was conducted using GPS on 21 August, we selected three spots for the soil survey, each of which was different from others. These three spots were represented respectively by natural pasture land, wheat field and fallow field.

Fig.25 Soil survey

From 22th to 25th of August, soil investigation was conducted. We dug each spot about one cubic meter hold. To clarify the differences among them, we observed the soil profile in each spot and stuck monoliths on the soil profiles. Soil samples were collected from various layers to examine PH, electric conductivity, soluble cations and anions. Chemical analysis will be done in Japan. (4) Experiences of nomadic life and mutual understanding Some of us stayed in a ger which was a traditional house for nomadic people. We cooked every dish by ourselves and were forced to eat mutton every day. Water was not enough for washing hands and dishes. To the old style toilet we had to walk far a way from the house. At night we could see a clear milky way in the sky. We slept in each sleeping bag. The nomadic life was quite different from a modernized one we had in Japan.

Day 11 ( 26 August 2008, Tuesday) Trip to Karakorum Karakorum is an old capital 350km west from Ulaanbaatar. It is in Orkhon Valley, which is inscribed as cultural world heritage site by UNESCO. August 26 was a terrible day for us. More than two hours delayed from the appointed time, a bus came to the hotel at 13:00. To our surprise, the bus was too small for us. The bus had only 17 seats. Including Mongolian students, 24 persons would go to Karakorum. Some of the Mongolian students had to give up to go. One hour after the start, the engine of the bus did not work well. Two hours after, we exchanged the old bus by new one. It was indeed a good car. Taking the time of 10 hours to Karakorum into account, the arriving time would be 1:00 very early in the morning next day. Actually we arrived at a tourist camp at 0:30 mid-night. Day 12 ( 27 August 2008, Wednesday) Visit to Karakorum Karahorum was the capital of the Mongol Empire in the 13th century. In the 16th century the Tibetan Buddhist Erdene Zuu monastery was built near the site. Various construction materials were taken from the ruin. The actual location of Karakorum was long unclear. As the results of excavations, the site was conclusively identified as the former Mongol capital. We visited Erdene Zuu monastery. Mr. Katachulun, a teacher of Erdem Oyu University gave a lecture on the history of the Mongol Empire, during the tour around the monastery.

Day 13 ( 28 August 2008, Thursday) am Visit to Bayan Gobi desert Bayan Gobi is unique area combined with mountainous nature and desert-type landscape. We visited the small desert called as "Sand Island" located few km far from the tourist camp. We saw nothing but sands. There expanded beautiful dunes (sand hills). We could see the boundary between grassland to desert. "Sand Island" was a good example of the desertification.

Fig.35 Bayan Gobi desert

pm Return to Ulaanbaatar We left Bayan Gobi at 11:00 by bus and arrived at the hotel in Ulannbaatar at 18:00.

Day 14 ( 29 August 2008, Friday) am Summary Meeting In order to summarize our collaboration work and to discuss about future plan, the summary meeting was held in Erdem Oyu University. Mr. K.Iguchi served as a chairman. Four students summarized their works. N.Nishio talked about the experimental results on the solar power system. Our expectation was partly met but partly not. He proposed that the measurement should be continued by Mongolian students. Further exchange of technical information would be necessary. M.Mizukoshi talked about the construction of a light trap and the investigation of insects. The light trap system operated successfully. However because of the cold and rainy weather it was not confirmed whether or not the light trap was useful to prevent plants from the insect damages. He expressed his request to continue the work in next summer by Mongolian students. R.Akiho talked about the frame to support the solar panels. He found the necessity of its modification not to fall down against the strong wind. Putting the heavy weights could be effective tentatively to prevent the panels from falling down, he proposed. M.Hatakeyama summarized results of soil analysis. Three different places were selected for the analysis; (1)pasture land, (2)arable land cultivated for wheat and (3) fallow field. After digging the ground more than one meter in depth we observed the soil profiles and stuck monoliths. One of the monoliths would be left in the State University of Agriculture. Chemical analysis would be done in Japan and the results would be informed to Mongolian students.

S.Sato talked about the visit to Karakorum. He expressed his deep impression that Karakorum was the ruined town but still alive as the center of the Mongolian spirit in the heart of Mongolian people. There he found the mixing among Tibetian, Christian and Islam, which meant Karakorum was a great cross road of eastern culture and western one. D.Khishiingdelger, a student of State University of Agriculture, talked about the overall impression of the programme that the collaboration was fruitful. It was his pleasure to get many good experimental results through the collaboration work. He would continue the study of solar power. Prof. B.Buuveibaatar of State University of Agriculture summarized briefly that we made good success in the student collaboration between Japan and Mongolia. He also expressed his expectation that the good relation should be kept in future. Prof. K.Takeda of APU gave the students advice on "how to promote such kind of collaboration work". He emphasized the importance of the planning, keeping in mind about following 4 "W" and 1 "H", namely (1) Who and with whom will do it? (2) What will be done? (3) When will it be done? (4) Why will it be done? and (5) How will it be done? Before starting work, team members should have a consensus on 4 W and 1 H. K.Iguchi ended the meeting by the following summary. He said; "through the collaboration with students and teachers, we had valuable experiences. By the experimental work we obtained new knowledge and new skill. By living with Mongolian students in grassland, we could understand different way of thinking and way of living. We would like to keep our good friendship". Finally he expressed his thanks for warm hearted support done by Mongolian people. Closing Party We were invited to closing party by Prof. T. Dorj, the general director of Erdem Oyu University. It was held in a Chinese restaurant from 15:00 to 17:00.


Closing party

Day 15 ( 30 August 2008 Saturday ) Return to Narita Airport We left the hotel at 4:00 early in the morning by bus to the airport. At 6:30 we left Ulaanbaatar Airport on MIAT Mongolian Airline flight OM 501 for Tokyo. At 13:00 all members arrived safely at Narita Airport.


Outcomes and Future Plans

Our programme consists of several activities as mentioned in I-2. Main outcomes obtained from each activity and proposals are summarized in this section. (1) Lectures and Student presentations After the opening ceremony, four lectures were given. Three of them concerned on the present situations of Mongolia; First one was on the nomadic society, second one was on the energy, and the third one was on the economy. Japanese professor's lecture was on the soil degradation. The lectures were helpful for students to understand the importance of the present collaboration work deeply. Presentations and discussions lead to the mutual understanding among members participating in the programme. The lectures were followed by the student-presentations and discussions. Based on the friendship among members, we would like to found another collaboration work contributing to the sustainable development of the global society. (2) Collaboration work of Solar Power Generation: After the discussion of fundamental aspects of solar power generation, we constructed the small power station in Bornuur. The maximum amperage from the solar cells was measured to be 7.0A, which was 93% of the nominal output current. In Ulaanbaatar, we could not obtain "deep cycle" batteries suitable for solar power system. Charging and discharging tests were conducted by using various types of batteries. Figure.1 illustrates the result of the experiment, where two batteries were connected in series. Both were rechargeable 12V batteries with same nominal capacity of 100AH, but one was new (almost virgin) and the other was old. The measurement was carried out in the condition of almost fine and partly cloudy. At 11:00 am, the voltage of one battery (old battery) increased to 14.8V but the other one kept 13.3V. The charging current decreased with increase in the voltage of the old battery. These results revealed that the capacity of the old battery was smaller than that of new one. Charging current was restricted by the capacity of the old battery.

Fig.1 Result of charging test for the solar power system Discharging tests were also conducted. In our system, discharge process was controlled by a charge controller. To prevent the batteries from the over discharge, the charge controller was adjusted to stop the flow-out energy at a certain critical voltage of the batteries. The voltage of batteries decreased with the increase of the energy consumption. It was confirmed that the critical voltage was 22.8V in our system and at the critical voltage the charge controller shut off the current from the batteries. We could not operate the solar power system connected to proper deep cycle batteries. Performance tests should be carried out after replacing present batteries by new deep cycle batteries. In near future, we would like to discuss on the data of performance tests using modified solar power system. The solar cell panels were supported by the frame which was designed to adjust the panel angle depending on the solar position. We have not yet the effect of the angle change. We would like to ask Mongolian students to measure the variation of efficiency with the angle. (3) Collaboration work on Light Trap System The light trap system with two lumps was modified to that with four lumps. The modification of the light trap was successfully fulfilled, using electricity produced by solar energy. Its stable operation was confirmed. The measurement of the power of the light trap with high voltage metal nets revealed that its power consumption was 194W.

The ability of the light trap to capture insects was examined for one hour at night. The temperature was 10oC. Even though it was too cold for insects to fly in the field, many small insects, few butterflies and mosses were captured and the total weight of the insects was 1.7g. No grass hopper was captured. In day time, we also captured insects by hand, and we are trying to identify them now.

Photo.37 insects captured by the light trap

The light trap should be operated in hot season (from June to early August) when the activity of the insects is high. Hopefully huge amount of insects including grass hoppers would be captured for one night. The killed insects were collected in a plastic box attached under the lumps. As the box was partly transparent, most of the insects were attracted to the box, but not to the light trap. In future experiments, the box should be covered by obscure film. (4) Investigation of soil The soil investigation was made for three different spots (natural pasture, wheat field, and fallow field ). In order to select the spots, we measured the experimental field of the University of Agriculture in Bornuur to make a map using GPS. The map is shown in V-6. The accumulation layers of the carbonate were found in all three spots but the depth of accumulated layer was different each other. In three different places, we made three different monoliths. The monolith of the fallow field was given to the State University of Agriculture. We intended to analyze chemical properties of each soil in Japan, however the soil samples were rejected to export out of Mongolia by a custom officer at Ulaanbaatar airport. Mongolian professor is doing his best to send these samples with the export permission of Mongolian government. Hopefully after the chemical analysis of the soil samples in Japan, we could start scientific discussion with Mongolian members in near future.

(5) Experience of living in Bornuur and visit to Karakorum The experiences of nomadic life in Bornuur for five days were very valuable for Japanese members to understand the way of Mongolian living. It was not comfortable for us to live. We had insufficient water and insufficient electricity. A toilet was far from our house. We did not have any chance to shower. Our power to maintain activity was mainly supplied by mutton every day. However it was a good occasion for young students to recognize that Japanese way of living was sustained by huge consumption of energy, water, and materials. We understood that Japanese should modify our life style friendlier to the environment of the earth. The visit to Karakorum was impressive for us. Actually in Karakorum there was almost nothing which reminded us glory of the old Mongol Empire. On the ruined capital, a new temple was founded in 16th - 18th century. The history tells us that the prosperity does not last forever. We should learn why and how the Mongol Empire disappeared.


Comments and Suggestions

(1) Overall impression of the programme All members expressed their thanks to ACCU giving a great opportunity to collaborate with Mongolian students in the field study. We were satisfied to contribute toward the sustainable development. (2) Benefits we obtained from the programme We obtained many benefits through the various activities of the Programme. - To understand the importance of the sustainable development. We experienced the nomadic life with Mongolian students under the conditions of insufficient water, insufficient electricity and insufficient materials, which were quite different from those in Japan. We deeply understood that our modernized way of living was not friendly to the earth. - To understand the benefit by mixing of different thinking. Through discussion with Mongolian people, we understood that their ways of thinking were different from ours. Mongolian people have their own wisdom different from Japanese one. Mixing of different wisdom often creates new ideas. - To improve our skill for the promotion of a project. For most of the students, it was the first experience to collaborate with other members for one objective. This programme provided us with a good occasion to have skills to promote a project. - To improve our skill for communication with foreign people. We recognized that the communication was the most important to achieve the good results in the collaboration work. We tried to brush up communication ability and we are sure to progress. - To enhance challenging spirit against difficulty. In practical collaboration work, unexpected difficulties came one after another. We had to fight against them with a positive mind. This

programme provided us with many challenges to overcome ourselves.

(3) Suggestions to improve the Programme We were very happy to participate in the Programme. We believe that such programme provides young students with a good opportunity to understand the importance of global collaboration. We hope that ACCU enhances such activities so that more students may improve their mind and skill to collaborate for the development of the world. For mutual understanding, not only one way programme (in-bound or out-bound ) but also two ways programme ( mixing of in-bound and out-bound ) shall be implemented. For students far from an international airport, domestic travel fee shall be included into the budget of the programme.

1. To investigate soil profiles to clarify the difference between pasture land and agricultural farm 2. Further to clarify soil degradation is caused by present land use, i.e. pasture / agricultural pressure

Soil investigation

Soil investigation

Hypothesis 1 In farm Nutrient in soil will be absorbed and gone with agricultural products because fertilizer is not spread well. It will become rich field because crop residue keeps in soil and makes soil fertile. Amount of crop residue (input) and carrying out (output) keep their balance.

Hypothesis 2 In field There is deposition of organic matter in the top layer of desert soil. There is not organic matter and grasses grow on the sandy soil directly. Deposition of organic matter become thin because domestic animals radically eats grasses.

Soil investigation

Method Soil profiles are investigated after digging a hole as below. Decide borders between each soil layer and their characteristics. according to the soil section survey handbook. At last, we make soil monolith with some kit.

Soil investigation Tool Soil section survey handbook, scoops, plastic sheets, plastic bags, some instruments (hardness meter, pH meter, EC meter, Global Positioning System, digital camera, etc.)

identification of insect

Purpose 1. To identify insects which are caught on vegetables and by the light trap system 2. To compare between the two insects from their genus structure and diversity


It is easy to catch the flying insect with a light trap. It cannot catch the insect which is not so. It is caught a harmful insect by a light trap, but catches the insect which does not have influence on a beneficial insect and the crops. the light trap is caught a nocturnal insect. However, it is not caught by the insect active in the daytime.

We express our thanks to Dr.T.Dorj, general director of Erdem Oyu University, for his wonderful arrangement. We also greatly thank Prof. P.Buuveibaater and Prof. B.Baasansukh of State University of Agriculture for offering the experimental place to us. We always remind Mr. Katachulun of his king assistant from early morning to late evening everyday. Without good cooperation with Mongolian teachers and students, the gain from the programme would be small. We appreciate receiving kind support from Kuraray Co., Aiwa-shoji Co., and Soroptimist International of Honjyo.
