Natural processes and anthropogenic activities are the major factors that can deteriorate groundwater quality. This study provides an insight into groundwater quality and its drinking suitability in part of Rajasthan. The physicochemical analysis of parameters (pH, EC,TDS, Ca2+, Mg2+, Na+, K+, F−, HCO3−, Cl−, NO3−, and SO42−) was conducted in the...

Because of its threat to the quality of freshwater resources and human health, arsenic (As) pollution is important to scientific communities and policymakers around the world. The Mekong Delta, Vietnam, is one hotspot of As pollution. Its risk assessment of different environmental components has been well documented; however, very few studies focus...

IGES Centre Collaborating with UNEP on Environmental Technologies (CCET) has developed version III of the IGES-GHG calculator entitled "Estimation Tool for Greenhouse Gas (GHG) Emissions from Municipal Solid Waste (MSW) Management in a Life Cycle Perspective", a tool that enables to estimate GHG emissions from the waste sector in China in the Life...

Microplastics (MPs) have been identified as an emerging soil pollutant and a global environmental concern. Scientists have recently paid attention to the contamination of soil by MPs as their detrimental impacts on soil systems are largely unknown. MPs are considered to be vectors for other soil contaminants, such as potentially toxic elements...

Considering water as a limiting factor for socio-economic development, especially in arid/semi-arid regions, both scientific communities and policymakers are interested in groundwater recharge-related data. India is fast moving toward a crisis of groundwater due to intense abstraction and contamination. There is a lack of understanding regarding...

ビジョン創発型政策形成は、脱炭素や脱プ ラスチックなどの中長期的な政策目標の実現 へ向けた持続可能な社会のビジョンの共有、政策の完全実施前のビジョンに基づく社会実 験を包含している。そして、関係者間の連携によるビジョンの共創と社会の方向性に関する合 意形成と持続可能性の社会的側面が重視される。これは、SCP3.0 時代における持続可能性の課題は、環境政策分野にとどまるものではなく、広く社会技術システムのデザインに関 わるものであることに由来する。ここで提示した協働デザインによるビジョン創発型政策形成 のフレームワークは、研究者と政策担当者による将来シナリオ分析や社会実験による社会デ ザインへ向けた連携の重要性を明確に示すものである。

本稿では、 Hotta et al. (2021) での議論に基づき、持続可能な消費と生産（ SCP ）の政策概念が、汚染防止とクリーナープロダクション（ SCP 1.0 ）から、製品・物質のライフサイクルアプローチ（ SCP 2.0 ）、さらに消費と生産を駆動する社会技術システムのシステムレベルでの転換アプローチ（ SCP 3.0 ）へと展開してきたことを報告する。その上で、社会技術システムへの転換が SCP 政策の目的となった 2015 年以降、 SCP1.0 と SCP2.0 で有効であった政策アプローチとデザインを意識的に更新する必要があることを論じる。最後に、こうした政策デザインの更新の方向性を Envisioning-based Policy Making...

Yasuhiko Hotta acted as a lectuerer and commentator for JICA training course on "Development of Recycling Policy" organied in January 13, 2022. The course was organized as an on-line training course and participated by the participants from Kosovo, Palestine, Thailand, Samoa, Cuba, Egypt, Georgia, Micronesia, Vanuatu, and Tunisia.

India has an ambitious renewable energy target for the decades ahead. However, the targets are faced with two critical impediments: (1) the lack of an internationally competitive renewable equipment manufacturing industry domestically and (2) the overdependency on external supply sources for equipment and machinery. The chapter finds that, despite...
