本分析では、北海道地域の275kVの基幹送電線を対象に、実潮流に基づく送電線運用のもとで、系統運用シミュレーションを行った。シナリオの前提条件としては、合理的と想定される既存の導入ポテンシャル推計結果に基づいて、系統に接続される風力発電の設備容量を1,950MW(2018年度450MWの4.3倍、発電電力量ベースでは7.8倍)、太陽光発電の設備容量を1,855MW(2018年度1,605MWの1.16倍、発電電力量ベースでは1.2倍)と想定した。それ以外の発電・送電設備は2018年度と同様とした。電力需要量や電力需要の時間及び地理的分布も2018年度時点のものとした。また、石炭火力・水力・原子力発電について、発電種別の調整力や稼働の有無といった電源運用の観点から3つのシナリオを設定し...

Debris cover on glacier surfaces hampers the accurate detection of debris-covered ice using traditional techniques based on image band ratios. Therefore, this study tests a new automatic classification scheme for hierarchical mapping of glacier surfaces based on machine learning classifiers including k-nearest neighbors (KNN), support vector...

Tonle Sap Lake is the largest flood-pulsed freshwater lake in Southeast Asia, supporting the livelihoods of millions of people living on and around the lake. However, recent changes in the lake water environment due to deterioration of water quality and decline in biological resources have caused various problems to local people living in floating...
Working Paper
Enhanced collaboration with countries with advanced technologies is essential to closing greenhouse gas (GHG) mitigation gaps in developing countries’ energy consuming and producing sectors. However, traditional models of technology transfer tend to focus on the sale of expensive technologies to developing countries, often subsidised through aid or...
Working Paper
中国にとっての2019年と2020年の前半は、世界経済の鈍化、米中貿易摩擦の長期化、コロナ問題の勃発など、山積の課題に対処しなければならない時期であった。米中貿易摩擦の影響もあり、中国の2019年のGDPは前年比6.1%の成長に止まった。 2020年1月-3月におけるGDP成長率は、昨年同時期に比べ6.8%下落するなかで開催した中国第十三期全国人民代表大会第3次会議では、内需拡大、雇用安定にフォーカスした政策パッケージを成立させた。  コロナ対策に関連する予算措置規模は、9.2兆元(約147.2兆円)と推計され、「新エネ自動車の普及とEV充電スタンドの拡充」や次世代通信設備や5G技術などへの重点的な投資方針も決まった。  2020年以降における中国経済のGDP成長率が不透明であるため...

A few studies have evaluated the impact of land use land cover (LULC) change on surface water quality in the Vietnamese Mekong Delta (VMD), one of the most productive agricultural deltas in the world. This study aims to evaluate water quality parameters inside full- and semi-dike systems and outside of the dike system during the wet and dry season...
Working Paper
While the initial pieces of evidence indicate that COVID-19 induced economic slowdown and lockdown present short-term benefits to air quality and the environment, these also pose a double-edged challenge in the long-term. On one side, the slowing down of the economy can have an adverse impact on countries’ ongoing efforts towards climate mitigation...

A few decades ago, the surface waterbodies in Hanoi, Vietnam, were an important source of water for various usages. However, because of the rapid global changes, the current status of most of the river system is very critical from the environmental, aesthetic and commercial usage points of view. Henceforth, this research work focused on assessing...
