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
