    Wheat is the key crop for world food security. It covers the largest area of sowing, and alone supplies almost 20 percent of the calories consumed by the world population. Wheat productivity is crucial to meet the increasing demand for food. Rust diseases are among the main constraints affecting wheat production globally, especially when suitable climatic conditions prevail. Rusts affect almost all wheat producing regions, from the Americas to Australia. Wheat production in East and North Africa, in the Near East and West, and in Central and South Asia – which account for over 37 percent of total global wheat production area – is severely affected by wheat rust epidemics. To provide support, FAO continuously reinforces collaboration with its partners to boost countries’ ability to detect and manage these emerging wheat rust races.

    Wheat is the most widely grown crop globally and a source of food and livelihoods for over 1 billion people in many developing countries. Rust diseases are historically the most damaging diseases of wheat. Their frequency, extent and impact has increased significantly in the last two decades causing global concerns. Their high capacity of developing new races makes most wheat varieties vulnerable to them. FAO is continuously re-enforcing its collaboration with partners to enhance countries’ capa cities in prevention and preparedness to rust diseases.

    Wheat is a source of food and livelihoods for over 1 billion people in developing countries. A major staple food crop in many countries, it is an important source of nutrition, providing on average 40 percent of per capita calorie intake. Drought, floods and diseases severely affect wheat production. Exacerbated by climatic stress, especially in rainfed areas, the impact of wheat diseases is expected to increase. During the past decade a number of virulent strains of wheat rust diseases have eme rged, causing global concerns to wheat production. The wheat stem rust race Ug99 is highly virulent on the majority of world wheat varieties – the risk that it could cause a global epidemic is real. Ug99 is well established in East Africa and Yemen and has spread to the Islamic Republic of Iran. In 2010 and 2013, a new, virulent strain of yellow rust, Yr27, has caused severe outbreaks and losses in many countries in North and East Africa, the Near East and South Asia. Due to ever changing geneti cs of these pathogens they need to be monitored continuously. Wheat production in Northern and Eastern Africa, the Near East and West, Central and South Asia is vulnerable to rust diseases. These regions account for around 37 percent of global wheat production. The cost of a 10 percent loss in areas at risk is estimated to exceed USD 5.8 billion. The impact on food and nutrition security is estimable. To combat wheat rust diseases continuous surveillance as well as a programmatic management appr oach are essential.
