A multifaceted perspective on environmental education as a social education
Get PDFBulletinThis study examines the challenges of implementing environmental education within the context of social education, focusing on its philosophy, objectives, learning content, implementation methods, and evaluation approaches. Social education lacks standardized instructional guidelines, resulting in inconsistencies across programs. Environmental education has evolved from pollution education to Education for Sustainable Development, playing a vital role in achieving the Sustainable Development Goals. The selection of learning content is supported by the Structural Constructivist Environmental Education Model, and progressive programs are needed to deepen learnersʼ understanding. It is also essential to consider the developmental stages of the participants and to foster intuitive understanding through observation and experimentation. Regarding evaluation, careful questionnaire design and application are necessary, along with the development of frameworks to assess changes in environmental awareness. Future directions include refining lake-based environmental education programs to create educational methods that contribute to building a sustainable society.departmental bulletin pape
Impact of paddy field around the Kotan River on the aquatic environment and aquatic organisms in Ishikari, Japan
Get PDFBulletinTo evaluate the impact of rice cultivation on river water quality, both chemical and biological indicators were use. In order to analyze water pollution and its effects on the ecosystem from multiple perspectives, surveys were conducted on the Kotan River in Ishikari City, Hokkaido, during the high season when rice cultivation uses the most water, and during the off-season after cultivation ends. In the midstream area in particular, levels of total phosphorus and total nitrogen were low, and electrical conductivity tended to decrease, which suggests a reduction in ion concentrations in the water. The results of the benthic organism survey showed an increase in species that prefer clean water, and the number of sampled organisms increased more than tenfold. The fish survey revealed an increase in fish size, suggesting a possible deterioration of the habitat. From these results, it can be said that water quality improved between the ear emergence stage and the off-farming season.departmental bulletin pape

The Efficacy of Mulching on Sweet Corn Growth : A Case Study in Ebetsu City, Hokkaido (2023)
Get PDFBulletin2023年5～8月にかけて，健土健民入門実習にてスイートコーンの生育に被覆資材が与える影響を評価した。2023年の気温は，6月中旬以降は収穫期まで平年値を大きく上回った。栄養生長と生殖生長のどちらも透明マルチ区において生育促進の程度がもっとも大きく，次いで黒マルチ区，無マルチ区の順となった。本試験より，マルチ資材によるスイートコーンの生育促進効果が確認され，地温上昇効果がより高いとされる透明マルチ区でその効果の程度は大きかった。一方で，雌穂重は黒マルチ区，無マルチ区，透明マルチ区の順に高くなり，マルチ資材による生育促進効果と雌穂重との関係性については，気象条件との関連性も踏まえて再検証すべきと考えられた。The effect of mulching on sweet corn growth was evaluated from May to August 2023. Temperatures in 2023 were well above normal from mid-June until harvest. The degree of growth promotion was greatest for the transparent mulching treatment in both vegetative and reproductive stages, followed by the black mulching treatment, and then the no mulching treatment. This study confirmed the growth-promoting effect of mulching on sweet corn in Hokkaido, and the effect was greater in the transparent mulching treatment, which is considered to be more effective in increasing soil temperature. On the other hand, ear weight increased in the order of black mulching treatment, no mulching treatment, and transparent mulching treatment, and the relationship between ear weight and the growth promotion effect of mulching should be reexamined based on the relationship with weather conditions.departmental bulletin pape
Development of solar-powered GPS collar for deer
Get PDFBulletinThe tracking period and positioning interval of GPS collars are typically determined by the battery life. If the system could generate its own power from sunlight, it would be able to track for long periods and at short positioning intervals, regardless of the battery life. In this study, we developed a new GPS collar model containing a solar power generation system. We deployed the collars on deer (Cervus nippon yesoensis) to evaluate their power generation and durability. We captured two deer in the Konan area in Akkeshi town on 25 and 26 July 2022 to deploy the GPS collars. Transmission from the GPS collars stopped at 12 days (collar no. 1) and 15 days (collar no. 2) after we began tracking. A total of 128 locations were recorded by collar no. 1, with a positioning success rate of 98.5%. In contrast, 139 locations were recorded by collar no. 2, with a positioning success rate of 80.8%. We found that the low strength of the case was one of the reasons for the damage caused to the GPS logger. Additionally, the amount of power that was generated by sunlight declined under the canopy and in the shade of buildings or terrain features. We conclude that stronger and more rigid materials are needed for the case and that a different type of solar panel that can generate power even under the forest canopy or in the shade is needed for the next model.departmental bulletin pape
