Introduction

 
FAQ
Does China's agriculture have a water problem?
Yes - it has at least three types of water problems. First, there is a serious water deficit in northern and north-eastern China. Rainfall is insufficient and rivers are frequently drying out. These water resource deficit is amplified by inefficient irrigation systems. Experts estimate, that poorly maintained and badly managed irrigation systems have water losses of up to 60%.
Second, provinces along the main river systems (Yangtze, Yellow River) have a high flooding risk. Flooding is the major reason for losses in cultivated land.
Water pollution from industries and untreated urban sewage systems is a serious problem in some agricultural areas that depend on irrigation. China has - by far - the highest total emission of organic water pollutants in the world. It is equivalent to the emissions of the USA, Japan, and India combined.
