Challenges in the Provision of Access to Clean Water

Background

A United Nations report on Human Development over a decade ago has already identified that “…overcoming the crisis in water and sanitation is one of the greatest human development challenges of the early 21st century”.

Today, 1 out of every 6 people in the world do not have adequate access to clean water. This has created tremendous public health problems and caused more deaths in the world than war. Every day nearly 5,000 children worldwide die from diarrhea-related diseases. Yet, water for drinking and personal use is only a small part of our total water needs. In addition to sanitation, most of the water we use today is for agriculture and industry. Of course, water is also needed for ecological processes not directly related to human use.

Thus, developing methods of ensuring adequate supply of clean water pose a great challenge to a healthy and sustainable future for our planet.
Objective(s) The talk aims to introduce the science and technology behind current and emerging approaches for clean water supplies.
