| Abstract | People in DuongLieu community have diversified economic sectors to get better income
sources and hence to improve their living standards.
There are seven major economic sectors, including traditional production. These are rice
cultivation, livestock, trading; starch and starch-based production namely, tapioca and arrow
root starch production, glucose syrup and vermicelli production. The starch and starch-based
production releases a large amount of wastewater characterized by a high BODs and a BODs
to COD ratio always higher than 0.6. This wastewater should be treated by biological
processes, and an anaerobic treatment seems the most economic. However, the wastewater is
now being discharged without any proper treatment, so it is heavily polluting surround
environment.
The Leontief input-output model is introduced to investigate environmental economic effects
of the starch and starch-based production. The community buys tapioca and arrow root from
other communities to produce various products, and they mostly sell this product to outside.
By using analyses of market variables, input-output flows in physical unit and in monetary
value for all economic sectors are built up. The technical coefficient-direct requirement
coefficient is used to arrange the matrix and then the inverse matrix is found.
Basing on the inverse matrix, two scenarios of economic effectiveness development and
environmental protection are analyzed. Under these scenarios, some alternatives with different
final users-final demand are considered. Not only change of starch and starch-based would
effect on pollutant output, but other change also. Trading is most important among seven
economic sectors, it should be encouraged to develop. With given final users-final demand, set
of total output of each economic sector would be determined. Pollutant output and appropriate
wastewater treatment is planed as well.
As a tool for analyzing and planning environmental economic structure, input-output model
should be more utilized and studied. |
