Importance of stopping groundwater irrigation for balancing agriculture and wetland ecosystem

The surge in agricultural water consumption to ensure food security in China has severely hampered the survival of wetland ecosystems. People ignore the importance of “lungs” in the process of meeting the needs for “stomach”. In this study, we quantified the direct and indirect impacts of agricultur...
