However, this is a clearly disappointing exploration outcome for this part of the basin.”“Shell will now cease … More Shell abandons Alaska Arctic drilling
Recently Science presented essays invited to debate key issues in freshwater research and management. Here the debate is about “when, and to what extent, should a global viewpoint replace, or work in tandem with, enduring localized perspectives?” Local perspectives on water “A global perspective on water management predominates in high-level policy discussions. This has the … More What scale for water governance?
Contemporary risk trend and future risk-trend growth. (Panel A) High contemporary values of R’ are distributed globally among the highly populated deltas of Southeast Asia and deltas in developing parts of Africa and the Middle East.

Abstract Construction of dams and the resulting water impoundments are one of the most common engineering procedures implemented on river systems globally; yet simulating reservoir operation at the regional and global scales remains a challenge in human–earth system interactions studies. Developing a general reservoir operating scheme suitable for use in large-scale hydrological models can improve … More A neural network based general reservoir operation scheme
