This week is World Water Week. The big event takes place in Stockholm Sweden where Stockholm International Water Institute SIWI is organizing this yearly event. The World Water Week is an unique forum for the exchange of views and experiences between scientific, business, policy and civic sectors from around the globe.
The last 10 years or so I have been working on various aspects of the environment. Though my main perspective has been scientific, the political framework set the scene and define the premises for even scientific discussions, particularly when it comes to funding.

Plastiki  is made out of – you guessed it – plastic. Plastiki, the plastic bottle version of Thor Heyerdahl's Kon-Tiki  , was carried from San Francisco to Sydney on a conveyor belt....and wind

I remember when water bottles were introduced on the Norwegian market. It was the most stupid idea I had ever heard of and could not imagine how anybody would be willing to loose their money on this bound to fail business project. Obviously I was wrong. Even in a clean country like Norway where fresh water is abundant everywhere there was a market for bottled water. Go figure.
The oil spill in the Gulf of Mexico is nothing but a plain disaster. It was of course a topic at ESA's Living Planet Symposium in Bergen this week, where use of satellites to help mitigate this environmental - and economic - disaster was on the agenda. But this is not about the science nor the politics of the oil spill.


Satellites are being used to look at practically everything you can think of. Well, maybe not. But if you take a single subject like ice, it is amazing how many ways you can look at it with a surprisingly large number of satellites.

A random visit to a session or two here at the ESA Living Planet Symposium in Bergen show a small selection of ways to look at ice from space.
