For nearly fifty years, applications of nuclear technology have been helping the world's farmers, contributing new varieties of crops, controlling pests, diagnosing livestock disease, improving soil and water management and increasing food safety.
The significant role of nuclear technology in supporting agriculture will be the focus of this year's IAEA Scientific Forum in Vienna on 18-19 September. Food for the Future: Meeting the Challenges with Nuclear Applications is the theme of the Forum, which takes place during the annual IAEA General Conference.
"Demand for food is rising significantly as the world's population grows," IAEA Director General Yukiya Amano said.
"Fighting hunger is a key priority. It is essential not only that the world should produce more food. We must also protect crops and livestock and make sure that food is safe to eat. Nuclear applications can make a real difference in all of these areas."
"The goal of the Scientific Forum is to make Member States more aware of the very important work of the IAEA in nuclear applications related to food and to encourage more countries to make use of our services."
Nuclear technology has many possible uses in food and agriculture.
By irradiation, scientists can accelerate natural spontaneous mutation and improve crop varieties to suit particular conditions. Farmers are benefitting from rice that grows in salty conditions, barley that flourishes above 4 000 metres (13 000 feet) and hundreds of other crop varieties.
The use of the sterile insect technique, in which males of a targeted species such as the tsetse fly or the Mediterranean fruit fly are sterilised by radiation and released into the wild, is expanding significantly. This effectively combats insect pests that damage crops and spread disease among humans and livestock, while limiting pesticide use.
The world was last year declared free of the deadly cattle disease rinderpest after a campaign made possible by nuclear techniques.
The use of such techniques to protect plants and animals against disease and pests means many more farmers can produce enough food to feed their own families and to sell on markets. Ultimately, fewer people go hungry.
The IAEA collaborates with the United Nations Food and Agriculture Organization (FAO) in providing support through a joint division in Vienna.
"While our profile is modest, the size of our footprint is significant," said Qu Liang, Director of the Joint FAO/IAEA Division of Nuclear Techniques. "We are putting the benefits of tried and tested nuclear technologies into the hands of farmers, particularly small producers in poorer countries, to improve their food security and livelihood."
"The assistance is driven by advanced technologies," Liang added. "But what we are delivering has to be appropriate to farmers' needs. That means crops that can flourish in changing and often harsher conditions, pest control without a chemical legacy and protection for livestock."
The Scientific Forum will be opened by the IAEA Director General and ministers from Indonesia, Kenya and Vietnam. FAO Director General Graziano da Silva will deliver a video address.
The Forum will address IAEA activities in the fields of food production, food protection and food safety. Each session features a panel of experts who will present and discuss the benefits of nuclear techniques in food and agriculture. A moderator will guide the discussions.
