Vast Sahara aquifers

An international team worked on the verge of the Sahara to gather data on the ground and in the air, to be compared with imagery of the same region acquired by ESA satellites. The results will be used in support of an ambitious project to apply satellite remote sensing to improve monitoring and management of vast water aquifers concealed beneath the desert.

Nature

The Saharan capacity, about 5 million square miles, for storing soil nutrients is foreseeably not limited and restoration of former Savanna by various groups in several Saharan countries, and elsewhere, have thus far made only small gains in what appears for them to be an intractable problem. Spending billions on “nature mimicking” sewage treatment plants while depriving soil and grass land of nutrients is just plain silly.

Sustainability baffle gab

I’ve spent the last few weeks surfing the “sustainability web” and with some uneasiness have discovered the word “sustainability” has not lost it’s meaning, but rather means something different to everyone who uses it. The word is greatly bandied about in design circles of every orbit and it is perhaps naive of me to assume that the world wide conversation on this topic was focused on the sustainability of life here on the only planet known to have any and by every standard of value measure ever devised or conceived of, the most valuable thing in the universe. So, when I discovered the focus of many sustainability conversations was in fact on self sustainability of various non living systems, organizations and professional relationships. I began, with a slightly vague feeling of despair, to look for the missing descriptors in the conversation . <!–more–>
