Abstract
The aim of this study is to quantify nitrogen and phosphorus flows in urban areas of Haiphong city by using Material Flow Analysis in order to identify weaknesses related to nutrient management in this region. The system boundary is defined by the five urban districts in Haiphong city, and eight components are included in the system model developed for nutrient flows in the urban area. Each flow in the model is quantified through literature and interview surveys. The visualization of N and P flows showed that, ordinary household activities are the processes that produce the highest amount of N and P loading to the environment. The main potential to mitigate environmental impact by these nutrients is the appropriate management of human excreta and wastewater from households.
