Mr Amano stressed the role of the IAEA in responding quickly to emergencies in Member States.
In response to the Zika virus, which has been confirmed in 70 countries, the IAEA has recently trained scientists from Member States in the use of a nuclear technique known as RT-PCR to help in the rapid diagnosis of the disease.
"It remains one of the most effective methods of rapid virus detection," he said. "We provided diagnostic equipment and materials to seven countries in Central America and the Caribbean, as well as to the Marshall Islands."
Mr Amano also highlighted the IAEA's work in responding to Lumpy Skin Disease, which mainly affects cattle. It made the RT-PCR technique available to a number of European countries.
In the area of food security, Mr Amano noted significant success in the development of new food crops which are adaptable to a changing climate. In Asia and the Pacific, 28 new crop varieties have been developed using nuclear techniques and released to farmers.

In his opening statement to a regular meeting of the Board, he highlighted the IAEA's recent activities in various areas, including nuclear applications, nuclear safety and security, safeguards and technical cooperation.
Mr Amano announcedthat the construction of the new Insect Pest Control Laboratory under the 31-million project known as ReNuAL has now begun. The construction of another facility, the Flexible Modular Laboratory, will commence soon.
"A total of 64 Member States made contributions to ReNuAL. I am deeply grateful to all of them," he said.
Mr Amano also emphasized the importance of securing global supplies of essential radiopharmaceuticals used in medical treatment. He noted that Australia's new ANSTO nuclear medicine production facility and France's Jules Horowitz Reactor, both of which he visited recently, will contribute to increased production of radiopharmaceuticals.
Turning to nuclear energy, Mr. Amano said there were 450 nuclear power reactors in operation in 30 countries and 60 reactors under construction.
The latest IAEA projections show nuclear power either maintaining its contribution to the global energy mix at current levels by 2030, or growing significantly.
Many countries see nuclear power as a low-energy source with significant potential to mitigate climate change. "It can assist Member States in meeting their commitments to reduce greenhouse gas emissions under the Paris Climate Change Agreement," the Director General said.
