Although environmental sustainability provides a foundation for maintaining economic and social sustainability, it is often neglected in favor of economic sustainability. Ameliorating water impairment is costly, and policymakers do not always prioritize this problem because its economic benefits are often intangible. This study explored the...

Peatlands in Indonesia are subject to subsidence in recent years, resulting in significant soil organic carbon loss. Their degradation is responsible for several environmental issues; however, understanding the causes of peatland subsidence is of prime concern for implementing mitigation measures. Here, we employed time-series Small BAseline Subset...

In this novel and integrated MAR approach, an offsetting scheme under the concept of payment for ecosystem services (PES) is used to enhance groundwater recharge along the Shirakawa River in Kumamoto Prefecture, Japan. The scheme gives a cash incentive to farmers who pond their abandoned rice fields for groundwater recharge. For a specified period...

In the early 2000s, Japan instituted the Great Heisei Consolidation, a national strategy to promote large-scale municipal mergers. This study analyzes the impact that this strategy could have on watershed management. We select the Lake Kasumigaura Basin, the second largest lake in Japan, for the case study and construct a dynamic expanded input...

Today, 54% of the world’s population live in urban areas, a proportion that is expected to increase to 66% by 2050. Major cities and municipalities in the region rely either fully or partially on groundwater. Four highly relevant Asian cities (Bangkok, Bandung, Ho Chi Minh and Lahore) were selected which bear groundwater dependency in the range of...

Modeling insecurity under future climate change and socio-economic development is indispensable for adaptive planning and sustainable management of water resources. This case study strives to assess the water quality and quantity status for both the present and the near future in the Ciliwung River basin inside the Jakarta Province under different...

This study is an effort to trace the implication of tidal fluctuation on coastal groundwater quality for different aquifers in case of Saijo plain, western Japan, through major ion, heavy metal and isotopic chemistry as well as to estimate aquifer parameters by tidal response method. Time series analysis for chemical characteristics depicts that...

With a population of 250 million, Indonesia is the fourth most populous country and second-largest plastic polluter in the world after China. The country produces 3.2 million tonnes of un-managed plastic waste a year, of which about 1.29 million tonnes ends up in the marine environment. In addition, approximately 10 billion plastic carry bags...
