Modelling future nitrogen pollution from agriculture in the Yangtze River, China

A PhD research by Xuanjing Chen

Research introduction

• The effect of seasonality on nitrogen export by the Yangtze River is still not well understood;
• The contribution of different crop systems to water pollution is not well studied for the Yangtze River basin;
• Maintaining food security with low environmental impacts on water quality in the Yangtze River basin is challenging in the coming years.

Research challenges

This PhD research is aimed to yield the following results:

• Newly version of MARINA accounted for seasonal Wu river export for N export will be developed;
• Newly integrated modelling system of MARINA-WOFOST-SWAP will be developed;
• The management options in agriculture to reduce nitrogen export by Yangtze will be explored.
