Agricultural Green Development pathways for food and water in China

PhD research by Qi Zhang

Research challenges

Agriculture often discharges pollutants such as antibiotics into surface and ground water. This causes negative effects on nature and society.

The main research objective is to explore future Agricultural Green Development pathways for clean water in the North China Plain and China in the 21st century.

For this, a multi-pollutant model will be developed to quantify inputs of pollutants to surface and ground water today and in the future. Agricultural Green Development pathways will be developed and integrate optimistic solutions to increase the availability of clean water under sustainable agriculture in the North China Plain and China.

Methods

Fig. 1: The research framework including four research questions (RQs). MARINA-Global is the Model to Assess River Inputs of pollutaNts to seAs by source from sub-basin in 2010. N is Nitrogen; P is Phosphorus; and AGD is Agricultural Green Development.

Expected results

First step: Model development for multiple pollutants from food production to surface and ground water in the North China Plain. The main focus is on antibiotics;

Second step: Develop Agricultural Green Development pathways for food production and water requirements in the North China Plain;

Third step: Assess the clean water availability under global change in the North China Plain;

Fourth step: Explore optimistic options under Agricultural Green Development for clean water availability in China.
