Seasonal variations in abundance of Oithonidae copepods were investigated from zooplankton samples collected weekly to biweekly at the two different stations in the Kagoshima Bay, southern Japan. Oithonidae copepods showed the similar pattern between the two stations, which they occurred abundantly from April to September and decreased below 10 inds./m3 during October to January. Abundance of each developmental stage was simultaneously fluctuated, indicating that it was a short development time. Nauplii, young copepodites and adult females were found over the study period, whereas adult males disappeared in some sampling periods between October and March. During this season, adult females and nauplii were at predominant stages. Females comprised more than 70% of adults, showing a longer life span than males. These results suggest that the decline of their abundance is caused by low rates of egg production, copepodite recruitment from nauplii and/or survival of young copepodites during the cold season although they reproduce throughout the year.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2012In Indonesia, in 2000 around 67% of domestic GHG emissions derives from Agriculture, Forestry and Other Land Use (AFOLU). It is important to evaluate quantitatively mitigation potentials and to specify countermeasures with large mitigation potentials. Using the AFOLU Bottom-up Model, we estimated GHG emissions and mitigation in AFOLU sectors based on a future scenario, harvested area of crops, number of livestock and land use change. Based on the analysis, in 2030 we found that GHG emissions in AFOLU sectors are expected to increase by 2.5 times at the 2000 level in the BaU case. 75% of emission in 2030 derives from peat land drainage. Under 10USD/tCO2eq of allowable abatement costs, 33MtCO2eq/year of GHG emissions can be reduced in agriculture, which corresponds approximately to 46% of agricultural emissions in 2000. Midseason drainage in rice paddies, fall incorporation of rice straw and high efficiency fertilizer application are expected to reduce around 11MtCO2eq/year. For the Land Use, Land-Use Change and Forestry sectors, enhanced natural regeneration, reforestation and avoid deforestation will be the most cost-effective countermeasures considering cumulative mitigation potentials up to 2050. インドネシアでは, 国内温室効果ガス(GHG)排出量の約67%が農業・森林・土地利用変化(AFOLU)に由来している. 排出削減効果の定量的な評価および高い削減効果をもつ対策の特定は重要である. 我々は, AFOLU排出削減評価モデル(AFOLUB)を開発したが, これを用いAFOLU部門におけるGHG排出緩和のための具体策を提示した. GHG排出量を推計した結果, 2030年において対策を実施しない場合AFOLU部門に由来する排出量は2000年比2.5倍の1.7GtCO2eqになることが示された. その75%は泥炭地の排水・酸化による. また, 2030年, GHG排出削減のための追加的許容費用10USD/tCO2eq下において農畜産業部門では2000年排出量比45%に相当する33MtCO2eq/年の削減が見込まれ, うち11MtCO2eq/年は水田での水管理および農閑期の稲わらのすき込みによる効果であった. 一方, 森林・土地利用変化部門については10億USD(2005~2050年)の資金制約下において, 長期的な視点での対策策定を行えば, 自然回復の強化, 再植林, 森林伐採の減少により, 2050年まで平均して約829MtCO2eq/年の削減効果が示された. これは2000年時点のLULUCF部門の排出量の1.2倍, エネルギー部門の排出量の約2.6倍に相当する. 地球環境研究論文集 第20巻

In this research, the situation and problems about the introduction of the biogas generating system using animal waste in Xinjiang Uygur Autonomous Region are clarified. It also comes up with some policy proposals for the development of the biogas generating system in rural China. 近年、世界的にバイオマス(生物資源)の利活用が注目されている。その背景には地球規模の環境・資源・エネルギー問題があり、各国において持続可能な経済発展への転換が求められている。中国では、三農問題解決の一つの手段として再生可能エネルギー法や農村地域の再生可能エネルギー発展計画を制定し、辺境地域の再生可能エネルギー開発を進められている。本研究では、バイオマスのエネルギー転換を進めている中国・新疆ウイグル自治区を対象として、家畜糞尿利用バイオガスシステムの導入の現状を把握し、その展開方向や問題点を明らかにする。

Recycling class here is a social studies class of elementary school fourth graders in which the significance of recycling-oriented society, waste sorting, Oki town's recycling activities, etc., are taught. The recycling class was undertaken as one of continual environmental education through searching for a method of collaboration between the town' Environmental Department and the board of education. Furthermore, from the perspective of service learing, the educational significance of recycling class was also studied.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2012In Indonesia, in 2000 around 67% of domestic GHG emissions derives from Agriculture, Forestry and Other Land Use (AFOLU). It is important to evaluate quantitatively mitigation potentials and to specify countermeasures with large mitigation potentials. Using the AFOLU Bottom-up Model, we estimated GHG emissions and mitigation in AFOLU sectors based on a future scenario, harvested area of crops, number of livestock and land use change. Based on the analysis, in 2030 we found that GHG emissions in AFOLU sectors are expected to increase by 2.5 times at the 2000 level in the BaU case. 75% of emission in 2030 derives from peat land drainage. Under 10USD/tCO2eq of allowable abatement costs, 33MtCO2eq/year of GHG emissions can be reduced in agriculture, which corresponds approximately to 46% of agricultural emissions in 2000. Midseason drainage in rice paddies, fall incorporation of rice straw and high efficiency fertilizer application are expected to reduce around 11MtCO2eq/year. For the Land Use, Land-Use Change and Forestry sectors, enhanced natural regeneration, reforestation and avoid deforestation will be the most cost-effective countermeasures considering cumulative mitigation potentials up to 2050. インドネシアでは, 国内温室効果ガス(GHG)排出量の約67%が農業・森林・土地利用変化(AFOLU)に由来している. 排出削減効果の定量的な評価および高い削減効果をもつ対策の特定は重要である. 我々は, AFOLU排出削減評価モデル(AFOLUB)を開発したが, これを用いAFOLU部門におけるGHG排出緩和のための具体策を提示した. GHG排出量を推計した結果, 2030年において対策を実施しない場合AFOLU部門に由来する排出量は2000年比2.5倍の1.7GtCO2eqになることが示された. その75%は泥炭地の排水・酸化による. また, 2030年, GHG排出削減のための追加的許容費用10USD/tCO2eq下において農畜産業部門では2000年排出量比45%に相当する33MtCO2eq/年の削減が見込まれ, うち11MtCO2eq/年は水田での水管理および農閑期の稲わらのすき込みによる効果であった. 一方, 森林・土地利用変化部門については10億USD(2005~2050年)の資金制約下において, 長期的な視点での対策策定を行えば, 自然回復の強化, 再植林, 森林伐採の減少により, 2050年まで平均して約829MtCO2eq/年の削減効果が示された. これは2000年時点のLULUCF部門の排出量の1.2倍, エネルギー部門の排出量の約2.6倍に相当する. 地球環境研究論文集 第20巻
