World Water Day This day, declared by the General Assembly of the United Nations, has been celebrated since 1993. The purpose of the World Water Day is to promote a global comprehension of the necessity of a more responsible use of this resource. On the occasion of the proclamation of this day, the different States are invited, within national context, to celebrate it and are proposed different activities, such as lectures, round-table conference, seminars or talks destined to make the people aware of the importance of conservation and development of water resources. Fresh water is essential to life. Humane sanity and social development depend on the availability of these resources, in quantity as much as in quality. Since 1.2 millions of people in the world do not have access to drinking water and since contaminated water and its shortage provoke 10 percents of illnesses in the developing countries, it is obvious that a lot remains to be done.

World Meteorological Day On this day, there is a celebration to commemorate the 1950 signing of the agreement for the creation of the World Meteorology Organization (WMO), as body of the United Nations to ensure the international cooperation in matter of meteorology. According to the WMO, statistics prove that there are more and more people affected by disasters related to meteorological and climatic phenomena. “This tendency is alarming since it prevents populations of the world from having a sustainable way of life”, pointed out the WMO secretary, Godwin Obasi, on the 23rd of Marsh of 2002.
