In China, the difficulty of this challenge is exacerbated by scale. With regulatory authorities spread across various agencies and municipalities, Chinese regulators are hard-pressed to present a unified front in tackling food safety challenges. As a result of these difficulties, food safety incidents are often front page news, shocking the world with stories such as ＂cadmium laced rice＂, ＂melamine tainted milk＂, and ＂re- packaged gutter oil＂.展开更多

Cereal rusts and powdery mildews are very important diseases occurred on the cereal crops, which caused yield losses at 5-10% in general and even more than 30% while severe epidemics occurred. In recent years, with the global climate change, change of cultivation system and evolution of the pathogens, the world is facing great challenges caused by cereal diseases.展开更多

Facing on the increasingly prominent international issues, it is very essential for relevant countries, international organizations and domestic counterparts to enhance systematic and mutual cooperation and exchanges to carry out scientific research and develop protection practice on the Eurasian steppe.展开更多

It is necessary to apply a dynamic and systematic approach to effectively man- age the complex agri-eco production and green processing systems. Indeed, farming systems approach for appropriate technology development and simulation modeling is a result of adopting the system thinking by the agricultural research community （Norman et al. 1995）.展开更多
