| الملخص: | This study focuses on the environmental pressure of waste generated from pig farming in
Yen Dung district. Terrain analysis of the digital elevation model (DEM) was used to delineate the
sub-basin map where pollutants accumulated. Then we combined this map with land use map and
statistical data for determining the distribution of pollutant discharged sources. Based on the
pollution load coefficient prescribed by the Vietnam Environment Administration, the loads from
all sources, including pig farming, were estimated for entire sub-basins within the district. The
results show that the pollutant load from pig farming accounts for a large proportion and creates a
major pressure on the local environment. The pollutant from pig farming greatly influences the
spatial distribution of pollutant loads across sub-basins. Therefore, special attention should be paid
to the waste management at pig farms (households and farm) to ensure the effectiveness of the
environmental protection for the communities. |
