| Research Abstract |
Nutrient balances may have changed drastically through urbanization in Nhue-Day river basin in Vietnam. To know the balances and their transition, this study estimated material flows of nitrogen and phosphorus in the basin with focus on waste-oriented regional resources such as human and livestock excreta. As results, agriculture has played a crucial role for nutrient recycling in this area. It was indicated that nutrients input to agriculture and output to the environment have increased recently ; the contribution of livestock excreta to the increase have risen due to a recentincrease of the livestock number through urbanization in the basin.
