Reducing point source inputs of nutrients to rivers and their impact on ecosystems and society in China

A PhD Research by Chen Xi

Research introduction

• Point sources are major sources of water pollution in China; few studies explicitly consider manure as point source inputs to rivers.
• The linkages between water pollution and water scarcity are not well understood.
• Interpreting model results at biophysical scales at administrative scales is a challenge.

Research challenges

A model will be developed to yield the following expected results:

• An updated database for point sources inputs to waters in China
• An integrated model to assess the impacts on both water quality and water quantity in China
• Indicators for water quality and clean water availability
• Effectiveness of management options for point sources in relation to local characteristics
• Scenario analysis based on latest climate and socio-economic scenarios
