Water Security is the new buzzword in the water sector… but what does it mean, really?
And how is it applied to real life?
In a world of rapid changes, unequal water resources, polluted water bodies, growing demands, and increasing climate variability and climate change, our relationship with water is quickly shifting. 
For countries and governments, the term national water security means having adequate water, both in quantity and quality, to meet all demands of the population, the productive sectors and the environment, but also dealing well with extremes, and overall managing the resource adequately and efficiently.
transformations: building human capacities (health, education, new job skills); decarbonising energy; promoting sustainable agriculture and biodiversity; building smarter cities; implementing the circular economy; and harnessing the digital revolution. As such, sustainable development and the 17 Sustainable Development Goals (SDGs) in particular pose a financing challenge.

lately. Policymakers are concerned that America’s leading firms such as the FAANG stocks — Facebook, Apple, Amazon, Netflix and Google — are having adverse results on the rest of us and making economic policy less predictable. Why is this? Many of the companies have improved the lives of people across the world with highly desirable and useful products. These superstar firms have also done very well for many of their stakeholders and investors. The numbers are staggering. These five tech companies together account for roughly half of the gains achieved by the Standard & Poor’s 500 stock index in 2018. And in recent weeks, Apple became the world’s first trillion-dollar corporation, with Amazon not far behind. While the superstar firms have made life easier for many consumers, it’s hard for economists not to wonder whether the effects of their stratospheric success are entirely benign.
