2013 has been declared by Unesco as Internal Year of Water Cooperation.
As an expert in water supply companies and PPP in developing countries, I want to point out this event.
It is also the occasion to announce another event, in the same field : a photography award on the subject :
Water in all its states.
Organized by International Mathematical Games Committee
(CIJM – Comité International des Jeux mathématiques).
Everybody can participate
