Pollution exacerbates China's water scarcity and its regional inequality
Overview
Paper Summary
This study reveals that inadequate water quality significantly exacerbates China's water scarcity, especially in North China, which experiences year-round scarcity. South China, despite sufficient water quantity, faces seasonal scarcity due to poor quality. This highlights the urgent need for integrated water quantity and quality management in China.
