More News Summary The world's water supplies are facing new threats; affordable, advanced technologies could make a difference for millions of people around the world. Today, the availability of water for drinking and other uses is a critical problem in many areas of the world.
How serious is our water challenge?
Lack of clean water is responsible for more deaths in the world than war. About 1 out of every 6 people living today do not have adequate access to water, and more than double that number lack basic sanitation, for which water is needed.
In some countries, half the population does not have access to safe drinking water, and hence is afflicted with poor health.
By some estimates, each day nearly 5, children worldwide die from diarrhea-related diseases, a toll that would drop dramatically if sufficient water for sanitation was available.
Globally, water is available in abundance. It is just not always located where it is needed. For example, Canada has plenty of water, far more than its people need, while the Middle East and northern Africa — to name just two of many — suffer from perpetual shortages. Even within specific countries, such as Brazil, some regions are awash in fresh water while other regions, afflicted by drought, go wanting.
In many instances, political and economic barriers prevent access to water even in areas where it is otherwise available. And in some developing countries, water supplies are contaminated not only by the people discharging toxic contaminants, but also by arsenic and other naturally occurring poisonous pollutants found in groundwater aquifers.
In addition to sanitation, most of the water we use is for agriculture and industry. Of course, water is also needed for ecological processes not directly related to human use. For a healthy, sustainable future for the planet, developing methods of ensuring adequate water supplies pose engineering challenges of the first magnitude.
Water contained in many groundwater aquifers was mostly deposited in earlier, wetter times, and the rate of use from some aquifers today exceeds the rate of their replenishment.
From digging wells to building dams, engineers have historically been prime providers of methods for meeting the water supply and quality needs of society. To meet current needs, which increasingly include environmental and ecosystem preservation and enhancement demands, the methods will have to become more sophisticated.
One large-scale approach used in the U. Such diversion projects provide some short-term relief for cities, but do not appear practical as widespread, long-term, ecologically sound solutions, and this method generally will not be able to meet agricultural needs.
Furthermore, diverting water to some people often means less for others and can become an explosive political issue. Desalination is not a new idea and is already used in many regions, particularly in the Middle East. Saudi Arabia alone accounts for about a tenth of global desalination.The persistence of high levels of non registered workers (informal workers) is a new characteristic of the labour market in Argentina.
In fact, this sector was almost residual until the ’90s, when it started to grow in a .

When Samuel Taylor Coleridge wrote “water, water, everywhere, nor any drop to drink,” he did not have the 21st century’s global water situation in mind. Peter F. Drucker, in his new book, Management Challenges for the 21st Century, provides insightful and timely information for individuals and organizations alike as they work toward common goals in the next one hundred years.
The growth of personal computing technology has revolutionized how people live and work in the 21st century. Keeping computer networks running at optimal levels falls on information technology managers, who must constantly upgrade their skills to keep up with the latest technological changes.
