Water is one of the most precious—and often unappreciated—substances on Earth. It is not only needed for agriculture, industry, and energy production, but is also essential for the survival of most plant and animal life. Where it is plentiful, it is frequently taken for granted. Where it is scarce, it is a valued commodity and always front of mind. Given the challenges of living in a water-insecure environment, what can we do to alleviate the uncertainty of water availability? What technologies can be brought to bear that may improve water security? Qatar, a desert nation with decades of experience managing water insecurity, provides a perfect paradigm through which to discuss the hopes and challenges of a water-secure future. This panel discussion, recorded in Doha and part of the Qatar Foundation’s “Catalyzing the Future” series, focuses on how innovation can help address water security. Preeminent experts will share their views and expertise on this important topic in front of a live audience, covering topics such as the causes of water insecurity, what technologies are available to generate clean drinking water (including the pros and cons of different desalination methods), and the challenges presented by geography and local conditions in applying those technologies in different parts of the world.
