Figure showing the proportions of the global population under water stress per month in 2010
This Article supports SDGs 3 and 6 by assessing global human water stress for low to high environmental flow protection. The findings suggest that ensuring high ecological protection would put nearly half the world's population under water stress for at least 1 month per year, meaning important trade-offs are made when allocating limited water resources between direct human needs and the environment.

In this paper, we address the problem of humanitarian aids distribution across refugee camps in war-ridden areas from a network design perspective. We show that the problem can be modeled as a variant of multi-period hub location problem with a particular demand pattern resulted by the user's behavior. The problem has been motivated by a case study of Lebanese experience in Syrian war refugee accommodation. We elaborate on the complexity and real-life constraints and, propose a compact formulation of a mathematical model of the problem.
