Water Challenge - a blog by Peter Brabeck-Letmathe

Welcome

I hope this blog will create discussion about the important issue of water use and availability around the world.

Your comments and views are very important and I encourage you to help me build and develop the conversation.

Offshore aquifers: global panacea or optimistic prognostication?

“The ultimate origin of water in the Earth’s hydrosphere is in the deep Earth” . This is the conclusion of an international group of researchers, including two scientists from University of Alberta:

“The earth could be a major repository for water.” It may hold as much water as all the planet's oceans combined”, these researchers believe.

Following up on a comment she posted on my blog, I invited Renee Martin-Nagle, a Visiting Scholar at the privately financed Environmental Law Institute in Washington D.C., to write a short guest post on a fascinating new topic: fossil offshore fresh groundwater reserves as a global phenomenon, based on information in a post she originally published in the International Water Law Project Blog in reaction to an article in Nature by another group of researchers.

Thanks to Renee for her views on a complex issue, and an invitation to the readers of my blog to comment from as many different angles as possible.

Drought and groundwater in the Great Plains of North America

People quickly forget when it comes to ‘extreme weather events’. This was one of the main conclusions of the 2014 Great Plains Symposium in Lincoln, Nebraska last week. Forgetting about much more severe droughts of both the near and more distant past, many politicians were quick to label the 2012-13 drought in the farming belt of US Mid-West as the worst in history and to blame climate change for it.

But as research presented at the symposium showed, drought is a normal part of the climate in the Great Plains. And in the past these droughts were much more severe than the most recent one. It should not be too difficult to find information on an at-least-as severe drought in the region in the 1950, and the even longer dry spell of the 1930s, known as the ‘Dust Bowl’ when more than 5,000 Americans died.

Lester Brown on water for food

With Lester Brown, at the World Economic Forum, Davos, 2006

Today, Lester Brown celebrates his 80th birthday. As the founder of the independent Worldwatch Institute, which he set up in 1974, Lester is one of the pioneers of the environmental movement, but one who never lost sight of human needs.

According to Lester, "the biggest threat to global stability is the potential for food crises in poor countries." This quote is from his article “Could food shortages bring down civilisation?” published in 2009 in the Scientific American.

For years now, Lester has been recognised as one of the most influential thinkers about – and beyond – sustainability; you can find an overview on some of the awards and prizes he has received for his outstanding work in his biography.

World Water Day 2014: : UN-Water Best Practices Award for Public Utilities Board of Singapore (PUB)

Tasting Singapore’s ‘NEWater’

Some of the best news from this year’s World Water Day was the announcement of the UN-Water Best Practices Award for PUB Singapore, the city-state’s national water agency.

What is so special about Singapore’s water supply? Some months ago, after publishing a book on the topic, Cecilia Tortajada, President of the Third World Centre for Water Management in Mexico was kind enough to write a guest post about PUB for my blog.

Below are a few facts to tell you more about this highly successful organisation.

Water and energy: ten telling facts

The theme of this year’s World Water Day, on March 22, is ‘water and energy’, an important subject I feel deserves more attention, and one that readers of this blog will know I often write about.

As I’ve written previously, the complex connections between food, water and energy are unavoidably real and impossible to ignore. Here are ten reasons why:
