Image segmentation and geographic object-based image analysis (GEOBIA) were proposed around the turn of the century as a means to analyze high-spatial-resolution remote sensing images. Since then, object-based approaches have been used to analyze a wide range of images for numerous applications. In this Editorial, we present some highlights of...

Land use/land cover (LULC) maps are now being used across disciplines for many different types of applications, e.g., to analyze urban heat islands or rainfall-runoff dynamics. Traditional map accuracy metrics are limited in this regard, as they only assess LULC map thematic accuracy. In reality, some types of misclassification lead to larger...
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...

The introduction of renewable energy (RE) is essential for building a sustainable society. However, RE can cause conflicts between energy production and biodiversity conservation. This study conducted a scenario analysis to evaluate potential conflicts in the nexuses between energy and biodiversity for the Bekambeushi River watershed located in...
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...
Briefing Note
ポイント IPBES地球規模評価報告書は、自然は人類の生存やSDGs達成に欠かせない基盤であり、この基盤が急速に失われていると報告した。SDGsの達成や自然との共生に向けて、経済、社会、政治、技術をまたぐ変容(トランスフォーマティブ・チェンジ)が求められる。 生物多様性と気候変動は不可分の課題である。2℃の気温上昇でサンゴ礁が99%減少するといった予測結果が示すように、気候変動が生物多様性を大きく損なう。一方、気候変動緩和目的の大規模なバイオエネルギー生産は生物多様性や食料や水の供給を脅かす。こうした生物多様性と気候変動の相互関係についてIPCCとIPBESの合同技術報告書の作成が予定されている。 新型コロナウイルスの感染拡大から人と自然との関わり方を問い直す必要がある...
