As groundwater found in aquifers is the main reservoir of freshwater for human activity, knowledge future response to climate change key improving water management adaptation plans. We analyze climate-driven evolution levels unconfined 218 world's major basins global simulations following latest Intergovernmental Panel on Climate Change scenarios, run with models able capture feedbacks among cl...

Public agencies have discretion on the time domain, and politicians deploy numerous policy instruments to constrain it. Yet little is known about how administrative procedures that affect timing also affect the quality of agency decisions. We examine whether administrative deadlines shape decision timing and the observed quality of decisions. Using a unique and rich dataset of FDA drug approval...

O ver the course of the recent financial crisis, several large financial institutions experienced sudden, massive withdrawals of their usual funding sources. In the U.K., for example, depositors lost confidence in the bank Northern Rock and started a run of withdrawals that ended with the bank being taken into state ownership. In the United States, the investment bank Bear Stearns and the comme...

Qatar’s water resource has been largely overexploited, leading to the severe depletion of its aquifers and degradation quality due saline intrusions. Qatar envisions employing regional store via forced injection desalinated thus increase available from a few days two months. A strategy for implementation injections is proposed based on spatially distributed model groundwater flow at scale whole...

The southern Ogallala Aquifer continues to deplete due decades of irrigation with minimal recharge. Recently enacted regulations limiting groundwater withdrawals and the potential for farm profitability cotton production systems indicate driving forces increased acreage in Northern High Plains Texas (NHPT). This study focused on evaluating land-use change from corn or winter wheat under dryland...

Rivers are essential to aquatic ecosystem and societal sustainability, but are increasingly impacted by water withdrawals, land-use change, and climate change. The relative and cumulative effects of these stressors on continental river flows are relatively unknown. In this study, we used an integrated water balance and flow routing model to evaluate the impacts of impervious cover and water wit...

Groundwater represents a vital source of freshwater to meet distributed, rapidly rising demands for safe drinking water, irrigation and industry in low-income countries across the tropics. The hydrochemistry groundwater within deeply weathered crystalline rock aquifer systems that predominate at low latitudes, is determined primarily by long-term biogeochemical weathering parent bedrock. Here, ...
