Mapping Monthly Water Scarcity in Global Transboundary Basins at Country-Basin Mesh Based Spatial Resolution

Abstract: Currently fresh water scarcity is an issue with huge socio-economic and environmental impacts. Transboundary river and lake basins are among the sources of fresh water facing this challenge. Previous studies measured blue water scarcity at different spatial and temporal resolutions. But there is no global water availability and footprint assessment done at country-basin mesh based spatial and monthly temporal resolutions. In this study we assessed water scarcity at these spatial and temporal resolutions. Our results showed that around 1.6 billion people living within the 328 country-basin units out of the 560 we assessed in this study endures severe water scarcity at least for a month within the year. In addition, 175 country-basin units goes through severe water scarcity for 3-12 months in the year. These sub-basins include nearly a billion people. Generally, the results of this study provide insights regarding the number of people and country-basin units experiencing low, moderate, significant and severe water scarcity at a monthly temporal resolution. These insights might help these basins' sharing countries to design and implement sustainable water management and sharing schemes.

Recent advances in the “on–off” approaches for on-demand liquid-phase hydrogen evolution

Abstract: Hydrogen (H2) has been extensively considered as a clean and renewable energy carrier and the most promising alternative to conventional fossil fuels for future energy supplies due to its ultrahigh energy density and zero pollution. Selective “on–off” switches for on-demand liquid-phase H2 evolution are crucial and challenging for efficient utilization and production of H2. At present, the on-demand liquid-phase H2 evolutions are mainly controlled by five types of switches, namely catalyst-transfer switch, phase-transfer switch, pH-adjusting switch, temperature-adjusting switch, and light-adjusting switch. In this minireview, an overview of these “on–off” approaches with a particular emphasis on the recent advances in mechanism exploration and applications has been presented. Finally, we provide the future research directions and perspectives for overcoming the challenges in the commercialization of a promising approach.
