FAO celebrates World Food Day each year on October 16 to commemorate the founding of the Organization in 1945.
Events are organized in over 150 countries across the world, making it one of the most celebrated days of the United Nations (UN) calendar.
These events promote worldwide awareness and action for those who suffer from hunger and for the need to ensure food security and nutritious diets for all.
One of the biggest issues related to climate change is food security. The worlds poorest - many of whom are farmers, fishers and pastoralists - are being hit hardest by higher temperatures and an increasing frequency in weather-related disasters.
At the same time, the global population is growing steadily and is expected to reach 9.6 billion by 2050.
To meet such a heavy demand, agriculture and food systems will need to adapt to the adverse effects of climate change and become more resilient, productive and sustainable. This is the only way that we can ensure the wellbeing of ecosystems and rural populations and reduce emissions.
Growing food in a sustainable way means adopting practices that produce more with less in the same area of land and use natural resources wisely. It also means reducing food losses before the final product or retail stage through a number of initiatives including better harvesting, storage, packing, transport, infrastructure, market mechanisms, as well as institutional and legal frameworks.
This is why FAOs global message for World Food Day 2016 is "Climate is changing. Food and agriculture must too."
It resonates with the crucial time in which the day will be observed, just before the next UN Climate Change Conference, COP 22, from November 7 to 18, 2016 in Marrakech, Morocco.
FAO is calling on countries to address food and agriculture in their climate action plans and invest more in rural development.
By strengthening the resilience of smallholder farmers, we can guarantee food security for the planets increasingly hungry global population and also reduce emissions.
