The document discusses the ecological situations in Asia, highlighting the interactions between organisms and their environment, the health of ecosystems through the Living Planet Index, and the human impact on these environments via ecological footprints. It addresses various environmental problems in the region, including pollution, deforestation, urbanization, and degradation of land quality resulting from human activities. Furthermore, it emphasizes the need for sustainable development to meet the needs of both present and future generations while balancing ecological integrity.

 A system formed by the
interaction of a community of
organisms with their physical
environment
 An area where physical,
chemical, biological traits
and forms of energy like air,
water, soil, and organisms are
interrelating with each other
 Includes the whole complex
of physical factors forming
what we call environment

3. The Living Planet Index (LPI)
 Describes the health condition of the
planet’s ecosystems
 Sums up tracked populations of
vertebrate, terrestrial, marine, and
freshwater species, which include fish,
amphibians, reptiles, birds, and
mammals from all parts of the world

4. LPI Report 1990-2005

5. The Ecological Footprint (EF)
 Shows the extent of human demand on the
ecosystem
 Tracks man’s consumption and waste
generation on the ecosystem in terms of:
 The needed area for production
 Land and water needed to provide
ecological resources, services
 Land on which to build
 Land to absorb carbon dioxide

6. Humanity’s Ecological Footprint
1961-2005

7.  Agreed upon in response to the
United Nations conference on
Environment and Development
(UNCED) on the Earth Summit in
June 1992 at Rio de Janeiro
 Call for development to be
promoted in ways that are
sustainable and environmentally
sound

8. Sustainable Development
 Responsible development of the
environment to meet the needs of
the present generation without
compromising the ability of the
future generations to meet their
own needs

9. Sustainable Development
 Essence is defined by the Philippine
Agenda 21, Section 1.3
In the harmonious integration of a
sound and viable economy,
responsible governance, social
harmony, and ecological integrity
to insure that development is a life-
enhancing process.

10. Factors that Causes
Environmental
Problems in Asia

11.  Increase in human resources
 Increases the need for food,
clothing, and shelter
 Will eventually leave no nation
capable of providing its people
with the resources they need to
thrive

12.  Physical growth of urban areas
from being rural as result of
population immigration
 Effects include change in density
and administration services
 Urban population is fastest in East
Asia, South Asia, and Southeast
Asia.

13.  Urban areas with more than 10
million inhabitants
 Host strong interactions between
social, political, economic, and
ecological progress
 Asia has eleven of the world’s
ten megacities with six in the top
ten.

14. Metropolitan area, which is notably
warmer than its surrounding areas.

15.  The immediate change is seen in
the disposal of volume of waste
 Unfriendly environmental
technologies
 Travel distances
 New pollutants such as pesticides

16. Environmental
Situations in Asia

17. The introduction of harmful
substances into the environment
that causes instability, disorder,
harm, or discomfort to the
ecosystem.

18. Trees, along with the
ecosystem that supports
them and the tourism
they inspire, are now at
risk of serious damages
caused by sulfur acid
produced at factories in
China’s Shanxi province
carried by the wind
across the Sea of Japan.
Ice trees along the slopes of
Mt. Zao in Japan

19. In the same manner,
schools in southern
Japan and South
Korea have had to be
suspended as a result
of toxic chemical
smog from China’s
factories and sand
storms from the Gobi
Desert, caused by
severe deforestation.

20. The release of a liquid
petroleum hydrocarbon into
the environment due to
human activity, and is a form
of pollution.

21. • Collision of Sea Star with another
ship at the Gulf of Oman (1972)
• Blow-out of an oil well in Nowruz
at the Persian Gulf (1979)
• NAPOCOR in Pililia, Rizal (1994)
• The Semirara and Guimaras oil
spills (2006)
• Explosion at a chemical plant in
northeastern China spilled
benzene into the Songhua River
(2005)

22.  Decline in land quality
caused by human
activities
 Caused by soil erosion by
water and wind affecting
142 million hectares or 75
percent of all agricultural
land in the region
 Results to economic losses
due to the decline in
productivity

23.  Affected 1.9 billion
hectares of the world’s
lands
 The most affected area is
in Asia, about 24 percent
of the land in the region
 13 percent of arable land is
seriously degraded, 41
percent moderately
degraded, and 46 percent
seriously degraded

24. Science of soil
management and the
production of field crop

25.  The wearing away of
land by water
 Widespread
throughout the
Himalayas, South Asia,
Southeast Asia, and
large areas of China

26.  The movement of material by
the wind and occurs when the
lifting power of moving air is
able to exceed the force of
gravity and the friction which
holds an object of the surface.
 Far reaching in the dry belt
stretching from central Iran to
the Thar Desert of Pakistan and
India.
 The wind-degraded land in
eight countries of South Asia
alone is about 59 million
hectares.

27.  The process of turning
forestlands into dry lands,
nearing desert stature.
 By this process, the soil is
depleted of its organic
content and nutrients
resulting of to the exposure
of the latter to wind and
water erosion.

28.  Caused by the speed by
which man abuses his
environment through
extensive farming, repeated
burning, and careless cutting
down of the trees
 Results to major droughts
 Suffered the most by China,
Afghanistan, Mongolia,
Pakistan, and India.

29.  In Asia and the Pacific
region cover approximately
655 million hectares.
 Deforestation has become
one of the major problems
in the region.

30.  The countries experiencing
the fastest deforestation
are Bangladesh, Pakistan,
the Philippines, and
Thailand.
 Also caused by rapid
population growth.

31.  Water shortage
 Only a part of the
renewable water resources
can be extracted and used
in the region, owing to the
unpredictability of stream
flow between low water
and flood seasons, and the
inaccessibility of some
watercourses.

32. Process where soluble
salts precipitate from
water and accumulate
in the soil

33.  Poverty and creation
of slums and squatter
settlements
 Lack of basic
infrastructure

34. The variation of life forms
within a given ecosystem,
biome, or for the entire
earth.

35.  Refers to plant and
wildlife, respectively
 Increased agricultural
production has
resulted in the loss of
inherent habitat of the
region’s flora and
fauna.
