World Water Day: Urban Challenges and Opportunities

Half of the world's people now live in cities, according to the United Nations, and within two decades, nearly 60 percent of the population -- 5 billion people -- will be urban dwellers.

Developing countries feel the growth most directly, but even cities like Philadelphia are showing signs of population growth.

While cities are considered by many to be the most environmentally benign habitat for human beings, urban population growth brings challenges. Among those challenges are increasing stresses on water availability, access, and sanitation.

Cities are hard to sustain without reliable access to safe drinking water and adequate sanitation. Yet even in the industrial world, urban water and waste service infrastructure is not up to the challenge.

Scarcity of usable water around the world is leading to further challenges and economic constraints, according to William Brennan of Summit Global Management, a San Diego-based investment firm that specializes in water.

"The continued industrialization of emerging markets, growing global agricultural demand, and rising energy inputs are unstoppable trends that are all converging at a historic rate, making the water demand curve further accelerate," Brennan wrote to me recently.

Yet, with such challenges also come opportunities, especially where recycling and reuse and treatment of water and wastes are concerned.

In the US, start-up companies like Liberty Hydrologic Systems, BlackGold Biofuels, Cardinal Resources, and ET Water are coming up with innovative solutions to deal with treatment, filtration, and waste; while large utilities such as AquaAmerica and American Water tackle the infrastructure for drinking water and wastewater services.

Internationally, organizations such as charity:water and the Global Water Challenge are addressing clean, safe drinking water, and sanitation issues in developing nations. (Here is a comprehensive list of water related organizations: H20.)

"Good urban water management is complex and requires not only water and wastewater infrastructure, but also pollution control and flood prevention," as the organizers of World Water Day point out. "It requires coordination across many sectors and between different local authorities and changes in governance that lead to more sustainable and equitable use of the urban water resources."

It also requires innovative solutions and new ways of thinking about how we use, reuse, conserve, and treat our water.

One day each year hardly seems adequate to raising the awareness of water issues around the world, but it's a start.  As our cities expand and stresses to water supplies increase, it will become clear as...well...water that we need to pay more attention to this most precious resource.


NOTE: Join me and Dr. Paul Bowen of Coca-Cola, Larry Levine of NRDC, and Richard Murphy of Fortune for a webinar today at 1PM ET as we discuss water challenges and opportunities: Cities and the Global Water Crisis.

Clean Tech: Water, Water Everywhere; Time to Wade In?

Smarter minds than mine have been wading into water this week.

It's a part of the clean tech space that I've neglected thus far. Time to get a toe in the water and test it out.

Looking into TTEK, AMN, and CCC, thanks to @jmclarty.

Also taking a look at SWWC, AWK, and WTR.

I'm hoping the water is warm...

Wondering what ever happened to eMembrane, which had an interesting nanotech filtering technology.

And curious what's happening with Water Health International.

For another take on water and sanitation, check out Ashoka's Changemakers and Global Water Challenge competition, which just announced its winners: Tapping Local Innovation, the most innovative approaches to providing access to safe drinking water and sanitation.

(And you must check out India's Oscar-wiining director Shekhar Kapur, ("Elizabeth" and "Elizabeth: The Golden Age," who blogged on "Paani" (Water), his new film about the daily struggle for drinking water in the slums of Mumbai.)

Social Entrepreneurs: Global Water Challenge and Ashoka's Changemakers Announce Worldwide Search for Solutions to Water Issues

Global Water Challenge (GWC) and Ashoka's Changemakers have partnered to launch Tapping Local Innovation: Unclogging the Water and Sanitation Crisis, an online collaborative competition to discover and support entrepreneurs large and small who offer groundbreaking approaches to the most pressing water and sanitation challenges.

The Coca-Cola Company is contributing a lead grant of US$1 million to support the collaborative effort to find and fund truly innovative solutions that address the water crisis. This commitment and partnership were announced at the World Economic Forum at Davos today. The Forum has fostering Collaborative Innovation as one of its stated goals.

Most people do not think about water; they turn on a tap and clean water flows readily. But for more than 1.1 billion people around the world, access to safe water is a constant concern. Suitable sanitation facilities are in even shorter supply. A lack of basic bathroom facilities deprives 2.6 billion people of human privacy and dignity.

"We have both the resources and the will to live in a world in which everyone can drink clean water and use a safe toilet," said Paul Faeth, Executive Director of GWC. "This open source competition is unique in allowing social entrepreneurs working in the farthest corners of the world to connect with a dynamic community of experts and funders that can improve and expand the impact these entrepreneurs can have."

"Global Water Challenge seeks to make existing projects even stronger and connect local innovators with global investors who can bring solutions to scale. By partnering with Ashoka's Changemakers, Global Water Challenge has a platform to challenge the world's entrepreneurs to use their substantial talents to solve the world's water and sanitation crisis," says Charlie Brown, the executive director of Ashoka's Changemakers. Brown notes that the Changemakers Web site encourages collaboration and discussion to draw out and strengthen the most effective ideas.

Innovators can post their applications on the Ashoka's Changemakers Web site at www.changemakers.net now through March 26, 2008. During this time, applications will be available to anyone for review, comment and discussion.

Once the entry period has closed, a panel of judges, including Ian Callaghan, Director of the Microfinance Group at Morgan Stanley, and Dr. Sanjay Gupta, Chief Medical Correspondent on CNN, will select finalists and the global online community will vote for the winners. The winners will receive funds in recognition of their work.
