In order to observe and examine water
resource management in response to climate change, a Special Symposium entitled
“Climate Change and Water – Towards the 1st Asia-Pacific Water Summit and
Beyond” was held by the Japan Water Forum at the JETRO Headquarters, Ark
Mori Building 5F, Tokyo.
The term “global climate change” for the
future is, in fact, not entirely precise. Change implies a sudden and
measurable shift occurring at a particular time. Climate dynamics, however, do
not occur in such an abrupt manner. Therefore, the more accurate and realistic
term is climate evolution.
Climate evolution and its effects on water
have long been understood by humankind. People have learned how to adapt to
these natural processes. Climate evolution is not the primary cause of water
scarcity. Humanity observes and interacts with nature daily and, therefore,
possesses the capacity to understand and respond to it effectively.
Water scarcity is primarily driven by
demographic growth, natural population increases, and uneven population
distribution across the planet. The addition of more than one billion people
every 10–12 years presents a complex challenge that is not easily resolved and
may delay the achievement of the Millennium Development Goals. Furthermore,
much of this growing population resides in large cities and coastal areas,
creating new regions where access to water resources is increasingly difficult.
In many of these cities, water availability
does not match human demand as climate evolution progresses. Numerous major
cities have experienced or are projected to experience water shortages during
this century due to the absence of clear regulations and rapid response
measures to address urgent situations. At present, a critical strategy is the
mapping of water resources alongside population growth trends.
If human activities fail to safeguard water
quality, serious consequences for human life will follow. Major sectors such as
industry and agriculture are of particular concern, especially when activities
result in water contamination. Pollution threatens the availability of
untreated natural water sources and increases the difficulty of securing
sufficient water supplies.
Water conservation efforts must include
eliminating waste disposal in all forms. All waste should be recycled to
maximize its potential benefits. We must strive to minimize water use wherever
we are and in all activities.
Several collective actions that should be
undertaken by government, the private sector, and the general public include:
a. Preventing chronic damage to water source
areas by controlling water pollution from chemicals and other substances that
degrade river and spring water quality.
b. Preventing and combating pollution caused
by transportation accidents, fires, explosions, pipeline failures, and similar
incidents.
c. Safeguarding and supervising clean water
treatment facilities.
d. Regularly monitoring both the quality and
quantity of water at each water source.
e. Managing water resources by maintaining
public infrastructure and regulating long-term water supply fulfillment.
f. Conserving water by preventing losses in
distribution systems and monitoring municipal water supply (piped water) usage.
