Erosions in Vietnam vary from
regions to regions due to different weather and soil conditions. We also
knew from our observations of the characters and changes in the geological
symptoms that a significant percentage is caused by man-made developments
and the lacking of planning in urbanization. Erosions are further complicated
by the lacking of infrastructure work and the continuous buildings
without much corresponding infrastructure plans and in-depth assessment of support
structures for the soil. Erosion control can be studied with advanced GIS
mapping, satellite imaging combined with other sensor and monitoring
systems. However. erosion control must start WHERE THE CAUSES BEGAN and
not where these cause ended. These cause are mostly excessive developments
by practically everybody from government servants, real estate speculators
from Taiwan, Korea, Japan, China... If richer people don't feel a sense of
urgency or responsibility, we cannot expect poorer
people to care because they
have neither the urgency nor the responsibility to live for in their
poverty-ridden life. |

It is not just naturally
caused higher sea
level, it is also man-made LAND SINKING in Vietnam. Land
sinking has been known for many years in river basins
around the World from Bangladesh, Thailand, Shanghai, Italy, Africa to
the Mississippi. However, none has the same compounding problems as in
Vietnam. Scientists agree that in certain low river basins such as HCM
city, Vung Tau, and the Delta, the land is sinking at
densely populated area as a result of sediment compaction, empty
ground waters (used up by people), soil degradation underground, sediments
and river flow problems, flood water with no ways to flow due to bad infrastructure,
escape routes plugged up by houses, plugged sewage (due to
heavy housing development and no planning) etc. This
sinking may be even faster and more damaging than rising sea level.
Both Dong Nai and Mekong River basins
are vulnerable to flooding
at populated areas. We recently have observed the conditions of the
areas of Q7, Thanh Da, Binh Quoi of tp HCM etc., houses are now BELOW
normal river level and flooding is daily just by raining alone. Soil
conditions are also weak due to no conservation efforts and continuous
heavy pollutions by people, businesses and industries wherever they
want and whenever they want. Further, the way houses are built in VN
cities, it is very treacherous to lift... If this situation continues,
the remedies are uncertain as options are limited.

>http://www.presscenter.org.vn/en/content/view/3422/89/<Professor
Le Van Trung, director of the Geomatics Center, University of Ho Chi
Minh City, told a seminar that the pace of land sinking has recently
accelerated due to rapid urbanization and unchecked exploitation of
underground water areas vulnerable to land-surface subsidence include
Thu Duc and Binh Chanh districts, districts 6, 7, and 8 with an
average sinking rate of over 10 millimeters a year. Trung spent 18
months to conduct a VND10-billion project using Dynamic
Interferometric Synthetic Aperture Radar, or Insar technology, to
detect and measure the ground surface deformation around the city.
Some streets such as Kha Van Can, in Thu Duc District, Vinh Loc, Binh
Chanh , Ton That Thuyet and Ly Chieu Hoang in District 6 and other
areas south of the city have subsided by 0.3 meter since 2000,” he
said.> |

Shoreline protection and
planning have not been seriously considered as damages are not often
seen except the developments and money being made. For the past 10
years, taking full advantage of development policy of local
governments, foreign businesses have pushed developments that never
include any stabilization and protection of shorelines by continued to
create activities close to water lines for more revenues. We now have
to pay for the rebuilding process. However, if we make an effort and
know how to engineer, fabricate products using locally available
materials, we can slowly rebuild inexpensively using our available
labor. VINAREX will participate in the design and fabrication of
erosion and beautification projects with local governments so the
people can enjoy what is left of our beaches. |

When overseas importers
and businesses learned of the deep forests in Vietnam, the first thing
they did was to bribe Vietnamese to clear, burn, chop, steal and
smuggle to them for money. Many persons did just that to get rich.
Forestry should be viewed as an important function of the entire life
cycle for other plants, animals and people. By better planning, better
education and by wisely prepare our land resources, we can rebuild
more than enough valuable wood to sell yet must also protect the
important ecological needs of nature, wildlife and society. VINAREX
will advocate intelligent planning and reforestation. Knowing what and
where to plant, we can make much better use of our forestry resources
and provide great alternatives for those who want to make an honest
living. |

PROMOTING
SAFE, NATURAL , RESPECTABLE AND SCIENTIFIC AQUACULTURE METHODS IN VIETNAM |
This subject matter is
complex and cannot be discussed within this site. We will devote
another website in the near future solely for the subject of
aquaculture in Vietnam. Within the limited space of this chapter, we
will summarize only the key issues or problem areas in aquaculture for
discussion. Our point is: We can meet the same profit ends without
using any Chinese made bio agents and hormone stimulants and at the
same time, we must respect nature and process the tons of wastes
instead of dumping them all into the rivers and ocean. Aquaculture
wastes in our current practices, contains harmful toxins and pathogens
that are dangerous for other species and for the health of both the
rivers and the people . |

aquaculture wastes |
Aquaculture
can be engineered with science and technology that do not abuse
nature. Bio-chemicals, hormone stimulants, growth stimulants,
heavy antibiotics, etc must be re-examined and changed. Aquaculture can be done
responsibly, safely, naturally and scientifically and still profitable |
In-land designs must be
least impact on the environment |
Feed must use less of
natural fish and come from known sources |
Fish wastes are filled
with toxins, gas, hyper-salinity, acids and must be treated as
industrial garbage |
Rivers, Ocean use must be
carefully studied and self-contained as much as possible |
Feed must be free of
pathogens, diseases, stimulants and other unknown animal sources |
As any industrial wastes,
they must be self-contained, discarded and processed as much as
possible |
We must also develop
in-land self-sustained and self-contained systems whenever possible |
Only known biological
drugs; no bio-chemicals, no stimulants, no genetically engineered drugs |
No wastes should be
released in to rivers and ocean to respect nature and our natural
resources |
On-site systems for
emergency use, for processing of wastes and other diseased fish |
Fish and water must be
frequently tested; diseased fish must be properly disposed |
As other food
manufacturing sites, hygiene conditions should be preserved and
practiced |
