With the mounting pressure of urbanization, how innovative blue-green infrastructure (BGI) can restore the ecosystem services of urban rivers is a timely issue for any densely populated city seeking to improve its resilience and sustainability through ecosystem-based solutions. Yet, the implementation of BGI is not hazard-free. Its success usually...

Tonle Sap Lake (TSL), the largest lake in South East Asia, is under increasing pressure from pollution, land-use change, climate change, and development activities in the lake, its basin and the Mekong Basin. Recent changes in the lake hydrological system and its floodplains are becoming a great concern for hundreds of communities relying on the...

インドを事例に、水不足が懸念される国における水とエネルギーの相互関係の重要性を長期的な視点から考察しています。そして、それらの国において持続可能な開発を実現する上で、水とエネルギーの問題を統合的にとらえた対策が不可欠である点を指摘しています。

水ストレスは世界的な問題であり、特に安全な水を利用できない人が多く暮らすアジアの途上国において重大な問題である。人口の増加等、長年の社会経済的要因に加え、気候変動が水ストレスに対する懸念の高まる一因となっている。本章では持続可能な水利用の推進に関し、特に政策ツールとして経済的手法の利用について以下に掲げる点について議論している。 ―水ストレスの増大に対処するには、新たな水源を開発するよりも、水利用のあらゆる局面で持続可能な水消費を推進すべきである。 • アジア各国で経済的手法（EI）を適用した事例から、EIだけでは持続可能な消費を推進できないことがわかる。 • EIの導入が貧困層の安全な水へのアクセスを必ずしも妨げるわけではないが、水道への接続費用の助成等、適切な資金援助が必要である。 •...

Water stress is a critical issue globally, in particular in developing Asia, where many people live without access to safe water. In addition to long-standing socio-economic factors such as population growth, climate change has intensified concerns over water stress.

Many Asian cities have greatly relied on groundwater in the course of their development. Large populations and concentrations of industrial activity in urban areas intensified the stress on groundwater. Such stress has resulted in environmental problems, such as the drawdown of water tables, land subsidence and saltwater intrusion, which interfered...
