Which of these international days is observed on the 16th of October?

World Food Day is annually held on October 16 to commemorate the founding of the United Nations’ Food and Agriculture Organisation (FAO) in 1945.

Since 1981, World Food Day has adopted a different theme each year in order to highlight areas needed for action and provide a common focus.

Most of the themes revolve around agriculture because only investment in agriculture – together with support for education and health – will turn this situation around. The bulk of that investment will have to come from the private sector, with public investment playing a crucial role, especially in view of its facilitating and stimulating effect on private investment.

This year, the theme is "The future of migration". The event will focus on investment in food security and rural development. In 2016, it was "Climate is Changing" and focused on climate actions for a sustainable future.
