WORLD WATER DAY
Water is a source of life. For example, water is needed
in all functions that take place in the human body (such as digestion,
circulation, breathing, emptying, reproduction). Therefore, the presence of
liquid water is being investigated in the search for life outside the Earth.
From
space, our planet appears as a blue sphere. That's because about 71% of its
surface is covered with
water. Liquid water is the most important substance
that separates the Earth from other planets in the solar system. Geological
evidence suggests that liquid water has existed on Earth for 3.8 billion years.
Usually
there are large differences between the melting and boiling temperatures of a
substance. However, water can be found in solid, liquid and gaseering at a
relatively narrow temperature range.
And is
the water the source of life as much as we think on our planet?
There's
water on Earth, equal to the volume of a sphere with a diameter of
1,386,000,000 sq km, or approximately 1,385 kilometers. 96.5% of the earth's
water is in the oceans and the rest is in the atmosphere, oceans, lakes, rivers
and glaciers in the form of water vapor. But fresh water is needed for the life
of living things. Fresh water accounts for only 2.5% (10,633,450 sq km) of
water on Earth.
Globally,
water consumption is increasing day by day. In addition, climate change due to global
warming, the frequency of extreme weather events and contamination of clean
water sources are causing the gradual depletion of clean freshwater resources.
A third
of the world's countries do not have access to water or are very limited. 18%
of the world's population does not have access to clean water. The reduction of
water resources leads to negative effects such as migration and epidemics.

World
Water Day
The United Nations and its member
countries have dedicated this day to rewarding concrete work on water resources
in the world and implementing United Nations recommendations. Every year, a
different organization of the United Nations working in the field of water
supports and coordinates the international events to be held on World Water
Day. Since its establishment in 2003, UN-Water has assumed the responsibility
of determining the UN agency that will lead the World Water Day events, the
topic of the event and the messages to be given.
Apart from the member states of the
United Nations, some non-governmental organizations supporting potable water
resources and aquatic life also consider World Water Day as a good opportunity
to draw attention to the priority water problems of our time. For example, the
World Water Council has been reaching thousands of participants for a week with
the World Water Forum, which it has organized every three years since 1997.
Among the issues that the participating organizations and non-governmental
organizations draw attention are issues such as “one billion people who do not
have the chance to reach clean drinking water” and “the place of gender in
accessing water in the family”.

Water Day
World Water Day
22 March “World Water
Day” reminds the importance of good water in human life, and emphasizes that
“GOOD WATER” is decreasing day by day as a result of environmental pollution
and population growth. Declaring 22 March as “World Water Day” was decided at
the United Nations (UN) Conference on Environment and Development in Rio de
Janeiro in 1992. WATER, and especially HEALTHY WATER, is an indispensable
object for human life, and it is even an “indispensable” substance that has no
alternative for human beings. Is it possible to make the world’s waters healthy
and improve “WATER for the Future” by commemorating and thinking about WATER
once a year?
For us, the readers and writers of the Journal of Water and
Environment, who recognize the importance of WATER for people, it is obviously
insufficient to think about and commemorate WATER once a year. However, if we
take advantage of March 22 and spread our WATER information around us, then in
a few years, the purpose of WORLD WATER DAY may reach a conclusion with a
geometric growth rate.
