St Hugh’s College, University of Oxford
April 16-18, 2012

The University of Oxford announces the agenda-setting conference:
Water Security, Risk and Society.

The link for more information and to submit your abstract is available here:

Places are limited and the closing date for abstract submission is 18
November 2011.

This symposium will convene leading scientists and members of industry and
government to advance the water security agenda and build partnerships
across theory, policy and practice.

Keynote speakers will include: Dr Don Blackmore (Member of the Order of
Australia, Former CEO of the Murray Darling Basin Commission), Professor
David Grey (University of Oxford), Professor Jerson Kelman (CEO, Light S.A.
Brazil), Professor Mike Muller (Commissioner, National Planning Commission
of South Africa; University of Witwatersrand), Dr Letitia Obeng (Chair,
Global Water Partnership), Professor Charles Vörösmarty (University of New

A series of panel sessions and presentations, including the open call for
papers, will examine the following themes.

Theme 1: Defining and measuring water security

• Sources of water security;
• Metrics of water security;
• Development impacts of water security;
• Current state of water security around the world.

Theme 2: Pathways to water security

• Managing risk and variability;
• Policy and institutional responses;
• Infrastructure, incentives and financial instruments;
• Information and technology;
• An agenda and timelines for action

Please see our website for further information on the conference.

Recipes from the Low Water Kitchen | Hydrophilia

Recipes from the Low Water Kitchen | Hydrophilia.

I just discovered Hydrophilia recently, and have been enjoying the writing and ideas of author “Water Deva” Wendy J. Pabich. This post is an interesting take on water conservation.  Discussion of water footprints is gaining ground, but still an unknown idea to most people.  This is a very practical application of the concept that makes it very personal and meaningful (at least it does to me).

In the coming years and decades, water conservation will become more critical than ever, and I believe we will need to take more extreme action to deal with it, what I like to call “radical water efficiency”.  Although eating foods with smaller water footprints does conserve water, it isn’t always water that will be available in the immediate area–with our current food supply system, it’s more likely to be halfway around the world somewhere.  Where  food is grown and processed may be just as important as what food is eaten, or how it is grown.

Bon appetit!

Grey Water Reclamation Uncovers Green Plant Opportunities – Industrial WaterWorld

Grey Water Reclamation Uncovers Green Plant Opportunities – Industrial WaterWorld.

When people hear “grey water”, they usually think in terms of capturing the water from showers and sinks, or possibly the clothes washer, to reuse in the garden.  But grey water (or graywater) may be available in large amounts in industrial settings as well.  In this case it may be rinse water from a process, such as CIP (Clean In Place), in addition to the more traditional sanitary sources.

Careful analysis is required for grey water reuse in the industrial facility, matching the level of contamination of the water, and the difficulty and expense of the treatment needed, to the potential end-use.  Check the linked article from Industrial WaterWorld for a more detailed discussion.

The Pyramid of New Water Sources

Here’s an interesting new tool to use when it comes to thinking about or teaching about water supply and conservation.  It’s called The Pyramid of New Water Sources and comes from  Jerry Yudelson , a noted green building authority and author.  I just found this in a blog post from World Water Day at Jetson Green.

A tool for prioritizing water supply sources by cost & complexity.

The Pyramid of New Water Sources

The Pyramid shows a progression of “new water” sources, ranging from the simple and free/cheap alternatives at the bottom to more complex and expensive at the top (with desalination and new water sources at the top).  Everything below the top level is about efficiency and reuse.  It’s a great reminder that when it comes to finding new supplies of water, using what we’ve already got more efficiently is almost always the most practical and cost-effective approach.
